Debian 6 offers updated applications, few rough spots, says review

Debian 6 will play well in server deployments that draw on open source components, as well as for desktop Linux users who require configuration flexibility, says this eWEEK review. Welcome additions are said to include Ubuntu's Software Center and a new GNU/kFreeBSD variant that opens up the open source OS to a wider audience.

Version 6 of Debian GNU/Linux, the popular open source project that bills itself as "the universal operating system," hit the Internet on Super Bowl Sunday, packing a trove of updated applications and a pair of new editions to burnish its universal billing.

The distribution, which already stands out for its broad processor architecture support -- spanning 12 architectures -- branches out in version 6 with 32- and 64-bit editions based on the FreeBSD kernel. These new editions, while rough around the edges, open new opportunity for technology-sharing among separate open source operating systems, and indicate that the project that gave birth to Ubuntu Linux continues to drive open source in new directions.


This latest release, which is also known by the Toy Story inspired name "Squeeze," will play well in server deployments that draw on open source components, which the Debian project has a knack for packaging up for easy installation over one of the project's repository mirror sites.


Debian 6.0 can also work well in a desktop role, particularly for users who wish to closely control the versions and configuration of the software on their machines. Debian is known, in its stable branch, for lagging behind the cutting edge in the versions of the software it ships, but once you become familiar with the distribution, it's possible to mix in applications from the project's testing, unstable, and experimental branches to tune one's environment.


GNU/kFreeBSD


The Debian 6 feature that I was most interested in checking out was the operating system's new 32- and 64-bit FreeBSD kernel variants, both of which carry a "technology preview" label.


While most Linux-based operating systems are simply called "Linux," the Linux open source project only produces the kernel of these operating systems -- the code wrapped around the kernel is the product of many different projects, the most central of which is the GNU project. GNU produces the C library and the constellation of applications (known as "userland") that makes Linux into a Unix-style operating system.


GNU/Linux and most Unix-style operating systems, including those distributed under an open source license, tend to be licensed incompatibly with each other, which has kept nifty, open source software advances, such as Sun's DTrace instrumentation framework and ZFS storage system, from making their way into Linux-based operating systems, even as these features have spread into more compatibly licensed Unix variants such as FreeBSD.


Debian's kFreeBSD flavor works around these licensing issues by marrying the GNU C library and userland with the kernel from FreeBSD 8. As a result, this version of Debian inherits the kernel features and hardware support of FreeBSD, while maintaining compatibility with most of the Debian software package catalog.


By sticking to the GNU C library, the kFreeBSB branch avoids many of the issues that troubled an earlier Debian project to port the NetBSD kernel to Debian along with the BSD C library. However, this key library difference carries its own complexity. For instance, DTrace is practically unusable in kFreeBSD -- at least for now -- due to missing userland components. For a Debian-style distribution with better feature compatibility with Solaris (albeit with fewer available packages) check out Nexenta.


When I spun up my first Debian kFreeBSD virtual instance, I noticed that FreeBSD lacks the enhanced "virtio" drivers that boost I/O performance with Linux or Windows operating systems running under KVM -- a difference that was noticeable in the time it took my Linux and FreeBSD-based instances to install.


Given my interest in kFreeBSD's potential for bringing previously inaccessible features into Debian, I was pleased to find ZFS as a partition option in the Debian installer application. However, over the course of several installations, I was unable to create an instance with a working ZFS partition from the installer. It appeared that the system wasn't installing the needed packages to get ZFS working. I was, however, able to create ZFS volumes once I'd finished installing and booting into a standard install with UFS-formatted partitions.


Installation and updates


I tested the amd64 version of Debian GNU/Linux 6.0 on a dual-core Dell notebook with 3GB of RAM, as well as on a handful of VMs (virtual machines) hosted under the KVM hypervisor on that test notebook. I created VMs for the 64- and 32-bit versions of the distribution in both its GNU/Linux and GNU/kFreeBSD configurations.


For most of my installs, I opted for Debian's network-based install media -- relatively small (around 140MB) disc images that reach over the network to Debian mirror servers to fetch the files needed for an installation. One of the benefits of this install route is that the system grabs all the pending updates during the install process, so there aren't dozens of packages to fetch after first boot.


Debian 6 is also available in a LiveCD version, similar to what other Linux distributions offer, which enables users first to try out the operating system before installing it on their hard drives.


Installing non-free firmware on Debian 6


Unlike most other Linux distributions, Debian 6 comes with an additional installation wrinkle. Depending on one's hardware, one must separately install any device firmware that fails to meet Debian's free licensing requirements. With version 6, the Debian project has managed to excise all non-free firmware from its default install sources -- a long-time goal of the project.


My test machine required such a non-free firmware file to drive its Intel 4965AGN wireless network adapter. The Debian installer prompted me to provide the needed file, which I attempted to do using a USB stick, but the installer couldn't detect the the firmware. I tried with FAT and ext3-formatted USB media, but to no avail. I forged ahead with my wired NIC, which did not require additional firmware, and fetched the missing firmware from Debian's optional non-free repository after installation.


Ubuntu's Software Center swims upstream to Debian


Once my system was up and running, I was pleased to note that some of the software management tools I'm accustomed to using in the Debian-derived Ubuntu have made it back upstream. In particular, Ubuntu's App Store-like Software Center, and its easy-to-use Update Manager tools, are available in Debian 6. Both applications put a friendly face on the distribution's massive collection of ready-to-install software packages. '




Embedded Linux file system rev'd for performance

The Reliance Nitro SDK for Linux 2.0 is the latest in a number of Linux-compatible file system products from Datalight, including the Datalight Flash File System announced in early 2008. That product combined the Linux version of the Reliance file system with DataLight's FlashFX Pro flash media manager and block device driver, an earlier version of the FlashFX Tera software mentioned farther below.

The new Reliance Nitro 2.0 SDK offers tools to validate hardware, including DCLTest, DevIOTest, and RelTest, says Datalight. Performance testing tools include FSIOTest and FSStressTest, while other tools help perform standard file system preparation activities such as formatting (relFsVolFormat) and integrity checking (relFsChk), says the company.


Reliance Nitro's platform-independent FSIOTest and FSStressTest performance and reliability testing utilities, meanwhile, are said to be compatible with any file system. Also included is a Reliance Nitro Windows Driver "for seamlessly moving data between a Linux system and a Windows XP, Windows Vista, or Windows 7-based system," says Datalight.


Reliance Nitro's tree-based architecture


Touted for providing faster performance and boot times, Reliance Nitro uses a tree-based metadata and "transactional extent-based" architecture. The architecture integrates a system of configurable transaction settings dubbed "Dynamic Transaction Point," claimed to balance performance with the amount of at-risk user data, says Datalight. It also provides immunity from file corruption, even after unexpected system interruption, claims the company.

The Reliance Nitro architecture is compatible with "virtually any storage medium," and maintains efficiency "whether an OEM is designing with hardware-managed or software-managed storage media," says Datalight.


Reliance Nitro can be used in combination with Datalight's Linux-compatible FlashFX Tera flash media manager for a complete flash memory based file system solution, says the company. FlashFX Tera supports over 300 flash parts, including MLC, and works with virtually any NAND controller, says the company. The software is also said to feature wear leveling, bad block management, and background compaction.


Stated Datalight VP of Engineering Ken Whitaker, "With Reliance Nitro 2.0, OEMs using Linux no longer have to choose between performance, reliability, a full set of tools and professional support."


Availability


The Reliance Nitro SDK for Linux 2.0 is available now at an undisclosed price. More information, including a number of videos, may be found at Datalight's Reliance Nitro page.

Atom E6xx PC is claimed to be world's smallest

Claims for the world's smallest computer and world's smallest SBC pop up every year or two in the embedded Linux world, it seems. The claims are usually true, for awhile, until the next, even smaller device comes along.

But what's amazing about recent entries, including the ARM-based Marvell Plug Computer, is just how powerful they're getting. The Xiilun, for example, crams a lot of horsepower into its 3.50 x 2.36 x 0.63 inches (89 x 60 x 16mm) frame, thanks to the Atom E6xx-based Topaz single board computer (SBC).


Toradex's Xiilun PC

The E6xx, matched here with an Intel EG20T controller and clocked at up to 1.6GHz, is heir to the original, low-power Z5xx line of embedded-oriented Atoms. The processor integrates an Intel GMA600 graphics controller, thereby reducing footprint.

Power consumption for both the Topaz and Xiilun is claimed to be "extremely low," although this wasn't quantified. According to Intel, the TDP of the E6xx processors ranges from 2.7 Watts for the 600MHz versions to 3.9 Watts for the 1.6GHz E680 and E680T.


The E6xx supplies the Topaz and Xiilun with full HD 1920 x 1080 resolution, dual independent display capability, and support for OpenGL ES 2.0, OpenVG, and DirectX 9.0, says Toradex. In addition, the processor's Intel hyper-threading and virtualization technology is supported. Video support for the SBC and PC is said to include MPEG4 and H.264 encoding and decoding, as well as MPEG2, VC1, and WMV9 decoding.


Topaz SBC

The Xiilun and Topaz each ship with 1GB or 2GB of DDR2 RAM. The Xiilun's ports are the same as the real-world interfaces on the Topaz: a bootable, internal microSD slot, a DVI-D port on an HDMI connector, as well as four high-speed USB 2.0 host ports, says the company.

The USB ports can be expanded through third-party USB peripherals for Wi-Fi, Ethernet, cellular, Bluetooth, and audio, says the company. This, of course, could make your world's tiniest computer not quite so tiny anymore, but it does offer some flexibility advantages.


The Xiilun's "robust aluminum die-cast housing" dissipates heat, allowing fanless operation, says Toradex. Operating temperature ranges were not supplied.


The underlying Topaz SBC, which is also available separately from the Xiilun, is not the world's smallest -- it's hard to compete with those tiny ARM9-based SBCs. However, the device appears to be one of the smallest Atom-based SBCs on the market, measuring just 3.3 x 2.16 x 0.5 inches (84 x 55 x 12.7mm).


While the Topaz's real-world ports qualify it as an SBC, not just a COM (computer on module), the device may be used as a module thanks to its two 50-pin expansion connectors. These allow attachment of customized I/O boards, offering features such as SATA storage,  PCIe expansion, or I2C and CAN interfaces, according to Toradex.


The Xiilun and Topaz run on 5VDC power and are available with long-time availability, says Toradex. The Topaz can be powered either over the EIAJ-02 coaxial power connector or over the expansion connector. The Topaz also supports suspend mode and hibernation, and can be configured to boot without power button interaction when a 5V power supply is attached, says the company.


Both products are said to ship with Linux pre-installed.


Features and specifications listed for the Topaz SBC include:

Processor -- Intel Atom E6xx at up to 1.6GHz; Intel IOH EG20T controller Memory -- 1-2GB DDR2 (32-bit) Flash expansion -- internal microSD slot Display -- 1 x DVI-D port on HDMI connector; supports HD (1920 x 1080) resolution, dual display USB -- 4 x USB 2.0 host ports Expansion connector I/O: 1 x LVDS (single channel) 2 x PCIe (PCI Express) 2 x high-speed USB 2.0 2 x SATA 1 x Intel HD audio 1 x SDIO (4bit) 1 x LPC 1 x SMB 1 x I2C 4 x GPIO 2 x UART (RS232) 1 x CANPower -- 5VDC; power management features Dimensions -- 3.3 x 2.16 x 0.5 inches (84 x 55 x 12.7mm) Operating system -- Linux pre-installed

Open source Snowball board taps dual-core Cortex-A9 SoC

As we mentioned briefly in our Feb. 16 coverage of ST-Ericsson's announcements at Mobile World Congress, the Snowball board will run on a Nova A9500, dual-core Cortex-A9 SoC clocked at 1GHz. ST-Ericsson offered scant information on the now sampling 45nm-fabricated SoC except to say it can ramp up to 1.2GHz speeds and includes Mali 400 graphics, full HD camcorder capabilities, and support for cameras up to 20 megapixels.


ST-Ericsson also announced a similar, but 32nm-fabricated, Nova A9540 SoC that will clock at up to 1.8GHz. In addition, it tipped a "Nova A9600" SoC using the upcoming, 28nm ARM Cortex-A15 processor core. The SoC will clock at up to 2.5GHz, and integrate Imagination Technologies' speedy "Rogue" graphics IP. Three Cortex-A9-based "NovaThor" smartphone platforms were also part of the jam-packed announcement.

Calao Systems' Snowball

Calao Systems' Snowball board, also known as the SKY-S9500-ULP, is the second open-platform, community supported development board we know of to incorporate a Cortex-A9 processor, after the October announcement of PandaBoard.org's PandaBoard. (The PandaBoard is distributed by Digi-Key, and is based on the Texas Instruments dual-core, 1GHz OMAP4430 processor.)


Another view of the Snowball
(Click to enlarge)


Both the Snowball and PandaBoard are supported with low-level Linux code supporting Ubuntu, MeeGo, and Android from the ARM-backed, not-for-profit, Linaro development firm. In November, Linaro demonstrated its Linaro 10.11 tools running on a variety of Cortex-A8 platforms such as the BeagleBoard, plus Cortex-A9 systems such as the PandaBoard.

The Snowball board is being supported by a new "Igloo" open source community, backed by ST-Ericsson, and managed by Movial. In collaboration with Calao and Linaro, Movial and Igloo will develop the final Android and MeeGo Snowball Software Development Kit and Snowball Product Development Kit based on the Snowball board and the Linaro codebase. While the Igloo site mentions only Android and MeeGo builds, ST-Ericsson says the board will also support Ubuntu.


The Igloo community offers an Igloocommunity.org web portal, where device developers, manufacturers, and application developers can gather, exchange information and ideas, and solve problems collectively, says ST-Ericsson. The principal targets for the board are said to be smartphones and tablets, but presumably a variety of other devices could also emerge from the Snowball.


Snowball specifics


To build the "production-grade" Snowball board, ST-Ericsson and its partners turned to French embedded firm Calao Systems, which is known for developing tiny, open source developer boards. These include the Linux-ready, 1.6 x 1.4 inch TinyCore single-board computer (SBC) modules based on Atmel's ARM9-based processors.

For the much more powerful Snowball, Calao moved up to a 3.35 x 3.35-inch (85 x 85mm) form factor. The Snowball backs up its dual-core, 1GHz Nova A9500 SoC with 1GB of LP-DDR2 RAM, as well as 4GB or 8GB of e-MMC memory, says Calao. A microSD slot is said to be available for expansion.

The Snowball provides a 10/100 Ethernet port, USB 2.0 on-the-go (OTG) port, and an RS-232 port, says Calao. An HDMI port supporting full HD is available, as is additional audio/video I/O, and debug connections including a JTAG port.

An Azurewave AW-NH580 wireless module supports 802.11b/g/n Wi-Fi, Bluetooth 2.1, and GPS, says the company. In addition, the Snowball is said to feature MEMS devices including a 3D gyroscope, accelerometer, magnetometer, and barometer.

A wide array of additional I/O is supplied via 16-pin, 60-pin, and 120-pin connectors. Together, these provide interfaces including cameras, LCD displays, I2C, SPI, audio, GPIO, and more.

Stated St?phane David, CEO of Calao Systems, "With its dual-core processor, combined with support for 3D graphics, HD video and HDMI output, Snowball is a multimedia powerhouse."


Stated Stephen Doel, COO, Linaro, "Developers will be able to come to the Linaro website and download the latest kernel, board support package and tools and know they are getting a great foundation to base their code or product on. Our evaluation builds and validation test farm will ensure that there is a quick way to utilize our engineering directly with the major software distributions on low cost boards such as the Snowball SDK and PDK."


Stated Tomi Rauste, president of Movial Creative Technologies, "Igloo is the one, unified space where Snowball users can quickly ramp up, get recommendations for hardware interfaces and peripherals, as well as complete software packages that are already aligned with open source requirements and standards."


Availability


Two versions of the Snowball developer board will be sold by Calao Systems starting in the second quarter. The software development version will cost about $200, while the product development version (also usable in end products) will cost about $300.

Wearable, Atom-powered computer ready for rough field duty

Both the Zypad BR2000 and DuraCOR 830 are touted for supporting so-called Size, Weight and Power (SWaP) constrained vehicle and aircraft platforms, as well as Command and Control (C2) applications. Both devices run Linux or Windows Embedded operating systems on different models of the Intel Atom. In addition, the company says it is considering adding Android to the Zypad BR2000.

Zypad BR2000


The Zypad BR2000 follows in the tradition of earlier Parvus field-ready wrist computers, such as the Zypad WR1100, released in 2008. In 2009, Glacier Computing spun off a U.S.-distributed version of the WR1100 called the Ridgeline W200.


Zypad BR2000

(Click to enlarge)

The Zypad BR2000 is described as a "soldier/worker wearable computer" or vehicle-mount subsystem available for a variety of civil and military applications. The BR2000 is designed to be worn on a tactical vest, utility belt, pocket or backpack, and to interface with optional, wrist-worn, vest-mounted, hand-held, or helmet monocle displays.

The computer weighs less than 1.8 pounds (0.8 kg) with its rechargeable, removable battery, or 1.4 pounds (0.6 kg) without, and offers four to six hour of typical battery life, says Parvus. Power consumption is said to run at about 5 Watts.


The 5.45 x 4.20 x 1.40-inch (138 x 107 x 36mm) device is protected by a submersible metal enclosure protected from water and dust, supporting MIL-STD-810G and IP67 standards, and offers a temperature range of -40 to 160 deg. F (-40 to 71 deg. C), says Parvus. Vibration and shock resistance are also said to be available.

Whereas the Zypad WR1100 and Ridgeline W200 run on a Marvell PXA 270 processor, the Zypad BR2000 moves up to last year's Intel Atom E660T ("Tunnel Creek"), clocked at 1.3GHz. This official heir to the original Z5xx line of embedded-oriented Atoms integrates a graphics controller (known as the GMA600) and offers only a relatively simple IOH I/O controller, thereby reducing footprint.

The Zypad BR2000 is equipped with 1GB of RAM, upgradable to 2GB. The computer offers a choice between onboard flash and CompactFlash, selectable in 16GB or 32GB amounts, and in standard or secure erase versions, says Parvus.


The BR2000 offers a VGA port, or optional LVDS port, as well as a composite video out port, says Parvus. The device is further equipped with a gigabit Ethernet port, six USB 2.0 ports, three serial ports, and audio I/O.


Customers can mix and match preferences for wireless options including Wi-Fi, Bluetooth, and 50-channel GPS, and one option provides connectivity to an external cellular modem. Buyers can also opt for battery packs or external DC power for in-vehicle use, says the company.


DuraCOR 830


The DuraCOR 830 is an update to last year's DuraCOR 820A Linux-ready tactical computer, which followed the original, circa-2008 DuraCOR 820. Like the DuraCOR 820A, the 830 uses the original, 1.6GHz Intel Atom Z530 (Parvus also offers a higher-end, Intel Core 2 Duo-based DuraCor 810-Duo).


DuraCOR 830

The DuraCOR 830 offers relatively few enhancements compared to the original, similarly offering 2GB of DDR RAM and nearly identical I/O. The principal addition appears to be a second, optional MIL-STD-1553 avionics port. In addition, flash storage limits have increased -- the computer now offers both an 8GB industrial solid state disk (SSD) preloaded with a Linux or Windows Embedded image, as well as a removable 16GB CompactFlash disk.

As with the previous model, all the I/O is brought out through lightweight, high-density MIL-38999-like connectors, making the product suitable for unmanned and manned command and control (C2) applications. In addition to supporting C2 operations like the Zypad BR2000, the more military-focused DuraCor 830 supports C4ISR (Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance) applications, says Parvus.


The computer offers dual open expansion slots for PC/104, PCI-104, or PC/104-Plus cards, says the company. As with the earlier model, the computer offers a gigabit Ethernet port, three USB 2.0 ports and two RS-232 ports. Other I/O includes PS/2, DIO, VGA, analog video, and audio ports. There are also the aforementioned, optional MIL-STD-1553 ports from Data Device Corp (DDC), which offer military-class databus connectivity.


The DuraCOR 830 supports operating temperatures of -40 to 160 deg. F (-40 to 71 deg. C) and meets MIL-STD-810G environmental specifications for shock, vibration, altitude, humidity, and immersion, says Parvus. Its corrosion-resistant, sealed aluminum chassis protects against water and dust ingress, and offers MIL-STD-461F emissions and susceptibility protection, says the company.


Weighing in at slightly less than four pounds (1.82 kg), the DuraCOR 830 measures 8.71 x 4.60 x 3.88 inches (221.11 x 116.84 x 99.55mm), says Parvus. The 28V power supply is said to be compliant with MIL-STD-1275 and MIL-STD-704 voltages, spikes, and surges.


Availability


Limited quantities of the Zypad BR2000 will become available by early Q2, with general availability by early Q3 2011, says Parvus. More information may be found on its Zypad BR2000 page.


Limited quantities of the DuraCOR 830 will become available by the end of Q2 2011. Parvus is accepting pre-orders now, but does not list a general availability date. More information may be found on Parvus' DuraCOR 830 page.

Google One Pass to challenge Apple subscription service

Announced on Feb. 16, Google One Pass is geared to kneecap Apple's subscription service for the iPad, iPhone and iPod Touch.

Google One Pass allows readers to purchase newspapers and magazines from publishers using a single sign-on with an email account and password. Publishers can offer subscriptions, metered access, and other custom content from their websites or mobile applications, while Google Checkout processes One Pass payments.


One Pass publishers collect 90 percent of sales on every transaction, says Google. The company's 10 percent cut is one-third of the 30 percent transaction fee Apple is charging for its App Store subscription billing service.


In Apple's App Store, publishers must offer users the chance to buy content in the application at the same price the digital content is offered elsewhere online. This move, the latest in a string of stringent Apple content policies, is sparking concerns among content developers.


Google has designed One Pass so that publishers can maintain direct relationships with their customers, which means they command all the data on subscribers who sign up through One Pass. Moreover, publishers authenticate existing subscribers so that readers don't have to re-subscribe to consume their content on, for example, a just-purchased Android tablet computer.


"Our goal is to provide an open and flexible platform that furthers our commitment to support publishers, journalism and access to quality content," claims Lee Shirani, director of business product management for Google Commerce, in a Feb. 16 blog posting on the One Pass.

Advantage Android

This sort of publisher-friendly freedom should ensure that Google will find plenty of traction for One Pass on Android smartphones and tablets at a time when Apple's iPad, iPhone and iPod Touch attract a lot of user eyeballs and time. Pairing publisher content with Android-based devices should in turn ensure that Google continues to serve a lot of ads via mobile search and other web services.


Google counts Media General, NouvelObs, Bonnier?s Popular Science, Prisa and Rust Communications among the first Google One Pass partners, as well as German publishers Axel Springer AG, Focus Online and Stern.de. One Pass is currently available for publishers in the U.S., U.K., Canada, France, Germany, Italy,and Spain, with plans to expand to other countries in the coming months.

Android 3.0 SDK released as Xoom starts countdown

On Feb. 22, Google made its full Android 3.0 software development kit (SDK) available to developers, more than three weeks after shipping a rough preview version to give developers a taste of the tablet-oriented "Honeycomb" build. The APIs are final, which means developers can write apps for the platform and publish them to Google's Android Market store.

Unlike previous iterations of Android developed for smartphones, the Honeycomb build is specifically for helping developers write apps for the larger screen size form factor of tablets.


Android 3.0 main screen from preliminary SDK build
(Click to enlarge)


In the blog announcement, Android SDK Tech Lead Xavier Ducrohet said there have been several improvements to the SDK since its initial run-through. These include UI Builder improvements in the ADT Plugin, and a new app palette with categories and rendering previews. Other touted enhancements include more accurate rendering of layouts, selection-sensitive action bars, and zoom improvements.

Honeycomb (logo shown at right), is arguably the most important Android build since the first version launched on T-Mobile's G1 smartphone in 2008. This is because Google intends the platform, which features a 3D graphics rendering engine and new application tools called fragments, to define the market for Android tablets to come.


Flash Player 10.2 heading for Xoom by late March


With a 10.1-inch screen, Motorola's Xoom will launch Feb. 24 as the first Honeycomb tablet. The tablet will cost $800 unsubsidized for a 3G/Wi-Fi version from Verizon Wireless and Best Buy, or $600 with a two-year contract from Verizon.


On Feb. 21, Adobe confirmed that its tablet-optimized Flash Player 10.2 will be available on the Xoom as an OTA update in late March. The announcement clarified a Verizon Wireless ad posted a few hours before that said that Flash 10.2 wouldn't appear on Android tablets until this spring. (Assuming the OTA update comes on or after March 21, Verizon may have been technically correct after all.)


As Wayne Rash notes in a Feb. 22 eWEEK analysis of the Xoom launch, Verizon Wireless is jumping out ahead in the tablet market by not only offering the Xoom (pictured at left), but also the hot selling Apple iPad and Android 2.2-based Samsung Galaxy Tab.


Other Android 3.0 tablets from Toshiba, LG, Asus, and others will follow in the coming months. In fact, a faster 1.2GHz, 4G version of the Galaxy Tab is heading for Verizon later this year.


Meanwhile, eWEEK's Don Reisinger argues in "Motorola Xoom is the perfect iPad competitor: 10 reasons why" that being the first Honeycomb tablet is only one reason why the Xoom is considered the leading contender against the iPad. Other advantages over the iPad are said to include a faster dual-core processor, dual cameras, and in a few months, 4G support.


Availability


The final Android 3.0 SDK is now available for free download. The announcement, with links to downloads may be found at the Android Developers site.

Voice recognition software

Voice recognition software is an extremely productive tool for people who
produce a lot of text. This software can write as fast as you can speak, and
with a bit of training, the accuracy is generally excellent. If you’re a writer,
for example, and you need to do an article on car insurance which can include
a lot of technical information, drafting time can be a real problem. Voice
recognition software can reduce hours of work to minutes.


Learning to use voice recognition software


This software uses a combination of voice recognition, vocabulary and training
functions to achieve accuracy. Because everybody speaks differently, and most
people unconsciously mispronounce words, there is some learning involved
– For both you and for the software. The learning process is actually pretty
quick, but you do need to be patient, and understand the situation in relation
to what you say and what the software transcribes.


This software effectively transcribes your speech, verbatim. It should be
recognized that part of the learning curve includes learning how to use the
microphone correctly, and practice is required. The voice recognition software
also responds to volume, and if your voice is too loud the likely result is that
you will get a transcription result different to that which you intended.


You will find that as you practice, your fluency and the accuracy of the voice
recognition software transcription will increase. Your speed will also improve,
usually pretty drastically, in the course of a week or so, depending on how
much you practice.


Voice recognition software for professionals


People producing a lot of text in the course of professional business, like
writers, lawyers, consultants and people in advertising and marketing,
can benefit greatly from voice recognition software. There is one caveat –
Accuracy.


It is absolutely essential to conduct a thorough editing of all text after
dictation. Voice recognition software is quite powerful, and surprisingly


sensitive. It is possible that small sounds may be transcribed as text, usually
because the mouth is too close to the microphone. Most voice recognition
software has noise reduction settings which are invaluable for reducing this
effect, but it is also advisable to do a full edit on principle for quality control
purposes, like normal proofreading.


The professional uses of voice recognition software are virtually endless, but
its greatest value is definitely improving the efficiency of drafting processes.
As most professionals know, drafting can be a true ordeal, involving the use
of a lot of time. In the car insurance article example referred to above, voice
recognition software makes it possible to deal with the important technical and
legal aspects of getting a car insurance quote, instead of spending a few hours
back spacing and correcting textual errors.


Voice recognition software used properly can achieve a quite high level of
accuracy and reduce the physical strain of typing. That’s great for the authors,
who can concentrate on the important content issues rather than painstakingly
producing text and cursing their typing speeds.


The good news – Good voice recognition software is comparatively cheap, and
very easy to install. If you’ve got a microphone, check it out.


Ubuntu 10.10 – Is it worth the hype?

UbuntuAs with any Ubuntu release, Ubuntu 10.10 has quite the hype train backing it, and its release. But this time, they backed it up better then most others. With the 10.10 release, they shipped a pretty impressive netbook edition, an updated installer and an opportunity to test it “in the cloud”.


Here are a few articles around the web that talks about some things Ubuntu 10.10:
http://arstechnica.com/open-source/news/2010/10/ubuntu-1010-arrives-with-impressive-new-netbook-environment.ars
http://www.extremetech.com/article2/0,2845,2370515,00.asp
http://www.linuxcritic.com/ubuntu-maverick-meerkat-10-10-review/


Once I have more time, I plan on giving better in depth reviews of the major Linux distributions again. Currently personally I’m running Fedora 13, but will be switching to to openSUSE 11.4 once it’s released.

Virtualbox Walkthrough: Ubuntu 10.04

This walkthrough takes you through creating a virtual machine on Virtualbox and installing Ubuntu 10.04 on it. This is a fairly thorough walkthrough, but by no means complete. When in doubt, consult the manual. It is assumed that you know the details of how to install Virtualbox, and Ubuntu as well. While neither of these are very difficult, both procedures exceed the scope of this text.


The host machine and OS is a Thinkpad T410 and Windows 7 64bit, respectively. The T410 (lovingly dubbed “Athena”) has an Intel Core i5-520M processor running at 2.40Ghz, integrated graphics and 4GB of RAM. However, these instructions should work on any machine capable of running Ubuntu and its host OS simultaneously. The version of Virtualbox used was the latest at the time–3.2.6.


When you open Virtualbox, you should see something like this:



From the default window, press the “New” button and the virtual machine wizard will load. The first window asks you to name your new virtual machine and which OS you will install on it.



N.B. You will see the “64 bit” option in OS type for Ubuntu. Use that ONLY if you are running a 32 bit host and you wish to emulate 64 bit:



If you want to use 64-bit guest support on a 32-bit host operating system, you must also select a 64-bit operating system for the particular VM. Since supporting 64 bits on 32-bit hosts incurs additional overhead, VirtualBox only enables this support upon explicit request.


On 64-bit hosts, 64-bit guest support is always enabled, so you can simply install a 64-bit operating system in the guest. (Source)


Clicking “Next” brings you to a slider that allows you to set how much RAM you wish to allot to your VM–how much RAM the emulated system will see. Don’t go past the green section or you risk freezing your host. I put 1.5GB, as Ubuntu runs fine with that much.



Next is configuring the virtual hard drive.



If you haven’t already created a hard disk, the wizard will walk you through that too. The virtual disk wizard has preset options that work fine. If you’re curious as what the differences between options are and don’t understand the brief description provide in the wizard, go read the manual.



Once you have configured your virtual disk, you should be led to this summary:



After hitting finish, you should see your new VM on the left. Select it and click “Start”.



When a VM in virtual box runs for the first time, the first run wizard pops up and asks you to load installation media. I’ve chosen an ISO image of Ubuntu 10.04 64bit. You can either use an ISO (easily downloadable from the ubuntu homepage), or a physical Ubuntu CD or DVD.



Ubuntu ISO booting:



Note: there are various alerts that will pop up that you should read at least once.


Now that the ISO is finished booting, you will be given the option to either try or install Ubuntu. You should know where to go from here.



Treat the virtual hard drive that Ubuntu detects normally. Partition however you are used to.



Installation takes a while. Go grab food or something.



Once the installation is complete, restart as prompted and you will boot into your new virtual Ubuntu installation!



Notice the low resolution. This is an indicator that Ubuntu doesn’t realize that it’s being run in a virtual environment. In order to fix this, Virtualbox has a patch called Guest Additions. But before that, update the system.



The first update generally takes the longest (unless you have an uber-fast connection). I got through a chapter of Hitchhiker’s Guide to the Galaxy and half a podcast of a college lecture before the system was fully updated. Ubuntu will probably ask for a restart so that it can load the updated kernel. Do so.


Once the desktop comes back up, go to Devices > Install Guest Additions. That will load an ISO into the VM’s CD drive. Ubuntu will detect it automagically and will want to auto-run it. I ignored that and opened a terminal and did the following:



This will install Guest Additions in Ubuntu.



After that’s done, it will ask to restart yet again. After boot you should notice a refreshingly better resolution:



Since it’s a virtual machine, I turned off the screensaver and power options, and enabled auto login.


Lastly, for whatever reason, Virtualbox crashes when desktop effects are enabled. This also occurs when I attempt to shutdown/restart/logout/etc with desktop effects enabled. So beware of that. YMMV. Cheers.


 

Puppet 2.6.2 on SLES SUSE Linux Enterprise

If you’re a puppet user and running SLES and have been looking for the latest version shipped via an RPM, then you’re in luck. I’ve been building packages recently for SLES and openSUSE with the recent releases of Puppet because in my organization I’ve implemented puppet to handle configurations (of sorts) for many of my servers (currently development).


You can get the latest packages using the openSUSE BuildServer in my repository, which can be found:
http://download.opensuse.org/repositories/home:/eclipseagent:/puppet/


Linux Kernel 2.6.30+ RDS Vulnerability

Blue Security LockRecently it was reported by VSR Security that Linux Kernel versions 2.6.30+ are affected by an exploit due to the implementation of RDS (Reliable Datagram Sockets).


Linus Torvalds has committed a patch upstream to close the exploit. VSR Security has released a proof-of-concept exploit, to show the severity of the exploit.


You can compile the exploit using:
gcc linux-rds-exploit.c -o CVE-2010-3904-exploit


Upon running the binary on an affected machine, you’ll get:



[*] Linux kernel >= 2.6.30 RDS socket exploit
[*] by Dan Rosenberg
[*] Resolving kernel addresses…
[+] Resolved rds_proto_ops to 0xf7f577b0
[+] Resolved rds_ioctl to 0xf7f52000
[+] Resolved commit_creds to 0xc04596eb
[+] Resolved prepare_kernel_cred to 0xc04595e9
[*] Overwriting function pointer…
[*] Triggering payload…
[*] Restoring function pointer…
[*] Got root!
sh-4.1#


For your machine to be affected you need to have to be loaded. Which can be checked with:
lsmod | grep rds
Which would return:
sh-4.1# lsmod | grep rds
rds 52948 4


If your machine is not affect the run of the above binary would result in a message like so:



[*] Linux kernel >= 2.6.30 RDS socket exploit
[*] by Dan Rosenberg
[*] Could not open socket.


Fluxbox on openSUSE 11.3

Are you sick of Gnome? KDE? or XFCE? Do you have a very old machine that you want to run Linux on, but the newer Desktop Environments are just too clunky? Well thanks to Linux, you have a choice of which Desktop Environment or Window Manager you want to use.


I personally use Fluxbox as my Window Manager, and have had a great experience with it on Fedora. So, I decided with the recent release of openSUSE 11.3, I’d give it a shot on the new distribution release.


I first started by installing openSUSE 11.3 onto my personal laptop, and opted for the minimal X install so that my machine wouldn’t be cluttered. After the installation I booted into the default Window Manager, TWM.


Next I added the Window Manager repository so that I’d have access to Fluxbox, and also added the X11:Utilities repository so I’d have access to feh, which is a great image viewer, and is also a application that will allow you to set your background while in various Window Managers.


*** Bonus ***
The Display Manager I use is lxdm, previously it was SLIM but SLIM seems to be pretty much abandoned upstream, so I decided to support the LXDE movement.


You can add the said repositories by doing the following:
sudo zypper ar -f http://download.opensuse.org/repositories/X11:/windowmanagers/openSUSE_11.3/ openSUSE\ 11.3\ WindowManagers


sudo zypper ar -f http://download.opensuse.org/repositories/X11:/Utilities/openSUSE_11.3/ openSUSE\ 11.3\ X11\ Utilities


Now, you can install fluxbox, slim and feh using:
sudo zypper in fluxbox feh lxdm


Now you’ll have to configure fluxbox to be your new default Window Manager, and configure LXDM to be your default Display Manager. We can do this using the sysconfig yast2 module, or we can modify the following files in /etc/sysconfig:
windowmanager
displaymanager


You want the following settings in /etc/sysconfig/displaymanager:
DISPLAYMANAGER=”lxdm”


And the following setting in /etc/sysconfig/windowmanager:
DEFAULT_WM=”startfluxbox”


Once you’re done, you can reboot (or just log out) and be greeted to a nice new LXDM installation, and log in to your nice new fluxbox installation.

openSUSE Announces Development Milestone Six of Six

openSUSE project manager Stephan Kulow has announced that openSUSE 11.4 Milestone 6 (M6) is ready for testing.  With M6, the pace of development is starting to slow down as the focus switches towards QA and bug fixing.


The project has been evaluating systemd vs SysV init to manage system and service startup, and has decided to stay with SysV init for 11.4 due to issues in getting the last 10% of the integration perfect.


M6 sees the completed removal of the HAL hardware abstraction layer, to be replaced with the more up-to-date and actively maintained udev, udisks and upower suite.  HAL was already scheduled for removal in 11.3, but it was retained while the last few software packages which depend on it were ported to udev and company.


Branding and artwork has had a lot of attention, with the addition of the final wallpapers, splash screens and branding for 11.4.  The default wallpaper is called Celadon Stripes, taking its inspiration from the color codename for this release.


New software added in Milestone 6 includes the WebYaST stack.  WebYaST is the web-based admin tool developed for SLES, now available for openSUSE. Professional sysadmins and those who just like to comfortably administer their openSUSE servers will appreciate WebYaST.  Also on the server side, the latest versions of the Horde groupware suite are now in openSUSE.


Software updates this milestone include the update of XOrg to 7.6, VirtualBox 4.0.2, GnuCash 2.4, and Scribus 1.3.9.  A lively discussion on the opensuse-factory list about whether to include the stable Firefox 3.6.13 or a Firefox 4 beta centered around the limited availability of popular extensions for version 4 versus the short upstream maintenance period of Firefox 3 releases.  As this article was published, the discussion was leaning towards taking a Firefox 4 beta and online-updating it to the final release when it becomes available.


Updates are flowing thick and fast to the KDE workspace and applications.   KDE 4.6RC2 is on M6, and will be updated to 4.6.0 final for the first Release Candidate.  The accompanying flurry of application releases include Amarok 2.4.0, Digikam 1.8.0, KOffice 2.3.1, k3b 2.0.2, KDevelop 4.2, KMyMoney 4.5, Rekonq 0.6 and BlueDevil 1.0.1.  Fans of the Oxygen style will also see it in GTK applications, thanks to the native port of Oxygen to a GTK style in the form of the oxygen-gtk package .


As the GNOME project prepares for GNOME 3, the focus at openSUSE is on stabilisation and polish to GNOME 2.32.  Bugfixes to PulseAudio, GDM and gnome-main-menu will ensure that 11.4 brings incremental refinement to GNOME users. Clutter 1.5 is included to support the latest available preview of gnome-shell, and the gramps genealogy tool is added in version 3.2.5.  The GNOME team is preparing an 11.4-based Live CD that will include GNOME 3 when it is released in March.


The XFCE desktop is updated thanks to the hard work of the community to version 4.8, bringing with it network transparent file management, a rewritten panel,  menus editable with Alacarte, and improved packaging and installation selections for openSUSE.


A list of most annoying bugs is being compiled; please check it before installing. We look forward to your bug reports and test experiences too. Automated testing and the openSUSE Factory team have been active to ensure that your download of M6 will be at least minimally functional.


Release Candidate 1 is scheduled for February 10 and brings with it a hard freeze.  openSUSE 11.4 is planned to be released in March 2011.

New SSL Certificates

We will be updating our certificates for *.opensuse.org and *.suse.de today, sometime between 19:00 and 22:00 UTC.  We will be upgrading to a 2048 bit certificate, which will provide better security for the site.  We are also switching to a different vendor who can provide us more efficient support.  We plan on chaining the certificate up to the Entrust root CA.

It is possible that a small portion of the community may experience some issues with this switch.  Specifically, any system previous to SUSE 10 may not have the Entrust CA in its system certificate store.  For these systems, utilities such as wget may present an error when trying to pull a resource from opensuse.org over an SSL connection.  The solution is to either run wget with the “–no-check-certificate” option or to add the Entrust root to the system certificate store (found in /etc/ssl/certs).  Browsers and cURL use their own certificate store and should not be affected by this switch, even on older systems.

If anyone discovers an issue after we make the switch, please contact webmaster@opensuse.org.

You can skip to the end and leave a response. Pinging is currently not allowed.

Counter for openSUSE 11.4

Apart from being a tasty Bavarian bread-snack, Bretzn is a code-name for a collection of
technology aimed at solving a problem which has existed in software development for a very
long time: “How do you get your applications to your users?”

Screenshots of the Bretzn plugin interface This is particularly a question for the many
developers of applications that are not part of a project like GNOME or KDE. These developers
must either provide binaries for a range of distributions themselves or hope that distribution
volunteers will do the packaging for them. Don’t they all dream of a better solution?

In the open source community, we already have many individual bits of this dream in place.
We have of course our powerful here
(scroll to the comments) Nokia might be interested in adding support for other
platforms like Windows and Mac OS X too! Moreover, we have the Open Collaboration Services
(OCS) which allows for the easy, socially networked publishing of packages both to and from
central software download sites such as openDesktop.org and KDE-Apps.org as well as
application stores like Meego/Maemo and we have many powerful integrated development
environments such as Qt Creator, KDevelop and Eclipse.

Until now these technologies and tools made up mostly isolated islands and it seemed an
obvious choice to try bridging them. A project aiming to do just this began in August 2010 and
was first publicly announced by Frank Karlitschek at the openSuse Conference in Nuremberg in late
October: Project Bretzn would make it possible, with a few clicks, to publish software
projects directly from the IDE – and it would all happen before the end of the year!

Connecting the Dots

Figure 1. The openSUSE application manager

Project Bretzn, then, is not a single piece of software, but rather an attempt to fill in
the holes which exist in what is already there. As it stands, the project has produced two
core pieces of software:

A thin client in the shape of a Qt Creator plugin, accessed through the Tools menu
in the IDE. The plugin lets you perform all the actions required to get data sent to the
various build services and publishing sites, by contacting the server part, which then
distributes the information to the appropriate places. The implementation of this also
prompted amending the Attica library with new features. As some will already know, Attica Figure 1, “The openSUSE application manager”is a full featured implementation of a OCS client library
built by KDE which is now officially included in the MeeGo platform. The Qt Creator
plugin is developed so that it is based on a thin library to make its functionality
easily portable to other IDE’s like Anjuta or Eclipse – consider this an invite!

A server library, designed to plug into the OCS reference server implementation as
published by the Social Desktop
project. This is the part of the system which draws the lines between the
dots: It contacts any number of build services that you request your software to be
built on and when you request it, it publishes the packages resulting of those build
jobs on the distribution sites and services. The publishing system requires only of the
remote sites that they implement the content module part of OCS, which many places
already do.

Figure 2. Ubuntu Software Centre (from wikipedia)

Moreover, work on a KDE client to download and install applications has started at the
recent openSUSE Bretzn sprint in Nuremberg. The screenshot in this article shows a first
prototype. And at the Cross-distribution meeting on an application installer, just before the Bretzn
sprint was held, it was decided the GNOME desktop will receive a client most likely based on
Ubuntu’s Software center. Figure 1, “The openSUSE application manager”

Most importantly, all this has the distinction of being open: not only is the source code
for the software above freely available as you would expect, but the web API created as the
communications layer between those two components is free and open, and indeed a part of the
Open Collaboration Services specification as of version 1.6.

Publishing Renewed

The best software is that which gets out of your way to let you do your work, and Bretzn
was designed with this in mind. What this means is that when you are ready to publish your
software, you call up the tool and enter the required information only once. If the same
information is required for multiple publishing sites, the plugin will take care of that. The
source archive is created for you when you select which folder contains your source code, and
you only need to select the targets you wish to build for to get binaries for your application
for all the platforms.

Even with the build services, building the binary packages does take a while. So, Bretzn
was designed to not require you to follow this all the time, but rather as a system in which
you create the build jobs, and then simply close the plugin and let the build service do its
magic while you continue working on other things.

When publishing the software, you will normally have to give notice to many people and
organizations if you wish for that knowledge to be spread. Through Bretzn, this information
can be pushed to these people as the publishing happens. Information can be shared through the
social networking features of the Open Collaboration Services on the sites the application is
published to. For example, users may be subscribed to updates about a single application, or
to activities performed by a friend, which are for example the publishing of
applications.

Who build it?

The project is a collaboration between h i v e 01,
Open-SLX and Nokia, and specifically it has been the task of Sebastian Kugler, Dan Leinir
Turthra Jensen and Frank Karlitschek to get the project working. Over the last four months,
they have been working tirelessly to construct the bridges which make up the Bretzn project,
both in software by writing the code, and socially by speaking with a lot of people about the
goals of the project to find out just what is needed, as well as making those whose systems
Bretzn bridges aware of what they have been doing. Part of the latter was being involved with
the Cross-distribution meeting on an application installer.

And, It Is Available Right Now

Though the majority of the code has been developed in the open, the various bits of code
have now been officially released:

The new version of LibAttica required for the tools was released

The Qt Creator plugin has been released

The OCS library extension has been released and is available

We invite you, the developers of the world, to use the results of this project and bring
your software to the world directly from Qt Creator and help us bring this to other IDE’s like
Eclipse but also vim and Emacs. And finally: Since all of this software is released under free
licenses, the team further invites you to join the development of the Bretzn components
themselves – not only in their current incarnations, but also to add functionality like
Facebook, identi.ca, blogger and Twitter plugins to spread the word there.

Work on an Application Installer to access the application has also started in the Bretzn sprint we recently had at the openSUSE offices in Nuremberg.

We will be updating our certificates for *.opensuse.org and *.suse.de today, sometime
between 19:00 and 22:00 UTC. We will be upgrading to a 2048 bit certificate, which will
provide better security for the site. We are also switching to a different vendor who can
provide us more efficient support. We plan on chaining the certificate up to the Entrust root
CA.

It is possible that a small portion of the community may experience some issues with this
switch. Specifically, any system previous to SUSE 10 may not have the Entrust CA in its system
certificate store. For these systems, utilities such as wget may present an error when trying
to pull a resource from opensuse.org over an SSL connection. The solution is to either run
wget with the “–no-check-certificate” option or to add the Entrust root to the system
certificate store (found in /etc/ssl/certs). Browsers and cURL use their own certificate store
and should not be affected by this switch, even on older systems.

If anyone discovers an issue after we make the switch, please contact
.

I have been using KVM a lot,
but never took time to understand how kvm works. I used some time from this hackweek to get
rid of that regret.

Virtual Machine eXtensions instructions allow trap-and-emulate virtualization. And KVM
exposes VMX in a convenient way to userspace in Linux. Virtual Machine Monitors(VMM) like
qemu-kvm use the KVM API exposed by linux to
emulate virtualize software.

x86_64 processors boot in real-mode. In this mode it can
use only 16-bit addresses, ie., upto 1MByte RAM. The execution would begin at physical address
0xFFFFFFF0. Then the software has to switch to protected mode
where protection and paging is possible. Paging is optional, but almost all OSes use demand
paging extensively. Now 4 GBytes of linear address space is used. And then CPU can be switched
to long mode i.e., 64-bit mode. Paging should be disabled in
32-bit mode, before switching to long mode. There are also other modes of operation like
virtual-8086 mode to allow executing legacy real-mode
software from protected mode, SMM for OS transparent
execution of OEM specific code.

I had limited time and very very limited skill at hand. So aiming for the sky was not an
option. Hence wrote a very simple VMM that directly starts
the guest at address 0H, in 32-bit protected mode with paging disabled. And supports only insb
and outsb as the only form of interaction possible for the guest. The guest is a simple
static linked 32-bit program that doesn’t use any library, and linked to start from
0×0. The guest simply reads a byte using insb and sends byte+1 back via outsb. The guest would
halt, when it gets the, “Answer to the Ultimate Question of Life, the Universe, and Everything“. The VMM
reads the byte value to pass to the guest from stdin and prints its response in stdout.

The KVM API is really very easy to understand and use. But some knowledge of the
processor was required to make use of it. Intel manuals helped there. I don’t have good
understanding of things yet, but something is better than nothing.

I was occupied by quite a lot of things in life and work in the recent past. So I wasn’t
really planning to participate and make this a real hackweek.
Also a National holiday for Republic day of India, bang in the middle of the week prevents this hackweek from
being a long hackweek! But seeing videos of my colleagues
from various parts of world having fun, I couldn’t resist and decided to go for the virtual hackweek. I thank my employer for giving me this protected hackweek, and let me learn/do things protected from
everyday work.

Last week we had a Hackweek at Novell. I decided to do something rather unusual for me –
to hack a device. I bought one of these nifty LiveView Figure 3, “LiveView Device” devices made by Sony Ericsson, which are basically an intelligent watch
that can connect to your mobile phone using Bluetooth. Unfortunately, it turned out to be
rather unusable with Android devices (lots of Bluetooth disconnects), but supposedly a
firmware update is on its way. After I saw that, I was somehow disappointed but I thought
there must be a way how to reverse engineer a protocol and try to connect the device to my
computer. I started to look around on the Internet and found a great blog by Andrew de Quincey. What was even more cool was
that Andrew already did most of the job and wrote some code in Python. All I had to do is to
wrap it into classes to make it more general and thus customizable. So what’s next? My dream
is to create a custom open-source firmware and flash the device. I hope I can achieve this
with help of hardware wizards from our Prague
hackerspace. The source code is available from gitorious as usual. Do you think that
Hackweek lasted only until Friday for me? Well, not really, keep reading … :-)

It’s been a long time since I was in touch with Enlightenment, back in the young days I
used it as my first alternative Desktop Environment on Windows, before actually daring to
switch to Linux.

Today I hear that version 1.0.0 of the core libraries have been released. Reason enough
to actually look into this again. So 1 hour, many build failures and successes later, I have
the entire core-stack built in my obs repository home:dimstar:Enlightenment. The window
manager Enlightenment itself is not yet released as full release, but the latest snapshot
can be found in my repo as well.

But that’s it so far: all core libraries are built. Nothing more. I did not even have
time to test them yet.

If you feel adventurous, go, add the repository obs://home:dimstar:Enlightenment to your
system (published for openSUSE 11.3 and Factory) and start playing with all of the things,
starting with the window manager, which should generally pull in the rest. What should be
required (as
root)

zypper ar obs://home:dimstar:Enlightenment Enlightenmentzypper in enlightenment

This will add my home repository to your catalog list and install enlightenment
including dependencies. One logout later, you should see Enlightenment as a new session type
in your *DM.

Have a lot of fun and share your experiences… I will test it after I get some
sleep.

I just pushed a new osc feature to git master which allows you to edit a submit
action. Use case: suppose you review a request (which has at least one submit action) and
you find a small typo (for instance in the spec file) but except the typo everything is
fine. So instead of declining the request you can fix the typo, create a new request
(which contains the fix + the original changes), accept the newly created request and
supersede the original request (that’s basically what osc does behind the scenes).

Example:

# request with id 80 needs a small fix marcus@linux:~> osc rq show 80 –edit Request: #80 submit: home:Admin/foo -> home:foobar/dest delete: home:foobar/xxx Message: deletes package xxx and fixes dest. State: new 2011-01-30T15:04:03 Admin Comment: A /tmp/osc_editsrr2iDcI/test.spec A /tmp/osc_editsrr2iDcI/src.tar.bz2 At revision 1. Checked out package ‘foo.home_Admin’ to /tmp/osc_editsrr2iDcI. \\ Started a new shell (/bin/bash). Please fix the package and close the shell afterwards. marcus@linux:/tmp/osc_editsrr2iDcI> # fix it and commit changes marcus@linux:/tmp/osc_editsrr2iDcI> exit exit Request: #None submit: home:Admin:branches:REQUEST_80/foo.home_Admin(cleanup) -> \\ home:foobar/dest delete: home:foobar/xxx Message: d(i)ff/(a)ccept/(b)uildstatus/(e)dit/(s)kip/(c)ancel > a -m “accepted request and \\ applied small fix” Supersede original request? (y|N) y marcus@linux:~>

By the way you can also do it manually (osc rq clone ; osc co project>; fix package(s) and commit changes; create a new request, accept it and
supersede original request).

Some time ago a openSUSE user mentioned to me if we had synapse available for openSUSE or
what was required to have it around. I took a look into it and asked some advice in
#opensuse-gnome regarding the availability of libzeitgeist which is one of the
requirements to build this piece of software.

Some time ago Federico Quintero has posted a message on
the opensuse-gnome mailing list regarding his work on the Zeitgeist stack. The rest of the
dependencies for this package are provided by my work on the availability of Ubuntu’s
software on openSUSE. From my work I took dee and libappindicator and builded a test package of synapse on home:ketheriel:ayatana. This package is here until I see this dependencies hit
factory on time (libzeitgeist, dee and libappindicator). If anyone wants to test it out,
go ahead.

I’m not sure of the functionality that should be present on this vala application, but
for the time being I’ve disabled the Application Indicator on the build (needs hammering
on the linking). I’ll take a closer look once I have some more free time. So far this
should be working only for openSUSE Factory and openSUSE 11.4 milestones.

Synapse is a semantic file launcher (pretty much the same as hitting ALT+F2 on a GNOME
session) with some crazy looks and a battalion of plugins. Once the dependencies are ok,
I’ll maintain this package and push it to the GNOME:Apps repository.

I have packaged up the latest and greatest release (0.1.1.1) of the-board from Lucas Rocha. If’ you want a bit more background
have a look at my previous post.

I also said that it was for 11.4/Factory only and that 11.3 was a WIP. Well the
progress is complete (with huge help from Frederic
Crozat, and his great GNOME3
repo).

Yes, more people can have some of this cool shiny stuff. There is a but, and this is
from upstream – it is still in development so you may loose a kitten or bunny, maybe even
both ;-) So come and join the fun and try it out, I’ve not generated a single .ymp
file yet so click on your version of Geeko

Off-late we have been working quite aggressively on improving our exchange
connectivity using Exchange Web
Services . Some evolution hackers sat together during GUADEC 2010 and discussed
on the focus areas which our community users as well as corporates would be interested in.
Exchange Web Services was on top of the list and David Woodhouse kick-started the work at
the same time! The development went on in David’s repo – http://git.infradead.org/evolution-ews.git and you can watch out the progress
there..

The festival season has started for evolution exchange and we have evolution showing
the folders, mails and meetings using Exchange Web Services. We currently just have the
read-only support for mailer and calendar at the moment and we are working towards
providing a complete support for calendar, mails and contacts.

Its always very nice to thanks all the contributors. Thanks to David Woodhouse who
kick-started it, Michael meeks he is always there :) , Johnny, Bharath Acharya, Akhil
Laddha, Chen, Fridrich who has been constantly getting it to compile on Windows…

There are more developers getting involved now and thanks to the organizations for
supporting the development!! We are looking forward to deliver the package by the
beginning of May 2011 for all the users.. One would be able to use EWS connector with
Evolution version 2.32 onwards..

I’ve neglected this indicator since the first day because it drove me into package
dependencies that aren’t used in openSUSE (we use YaST and not system-tools-backends and
friends).

The documentation of Unity suggests that if no indicators are present, Unity will use
the notifications from GNOME. This is very interesting, but from the debugging I’ve done
from the Unity Panel, I’ve found it it scans the indicators directory and loads whatever
it finds there. So it will eventually find something. One of the coolest features in Unity
Indicators and the one I’m currently working on, is ‘appmenu-gtk’ which removes the menu
from GTK+ applications and displays it on the unity-panel. This is interesting and the
behavior is actually a bit different from OSX. The window buttons are also placed very
close to this indicator.

If we have such feature enabled, I suppose the panel will always pick up at least one
indicator which might endanger the fallback to GNOME notification area. I’ve tested this
yet (unity isn’t launched properly yet), but if this happens, it will be wise to have the
whole stack of indicators. This explains why I had to build also this clock indicator
despite it’s wicked dependencies (liboost, not used on openSUSE).

This is how it looks and minimal functionality is already enabled, though
configurations aren’t because I haven’t implemented the whole backend, a nd if this
indicators are to reach Factory (which depends mainly on the patching on GTK+ and GDK
Pixbuf), there is the need to pass this packages through SUSE Security Team. If the
indicators are only to live on GNOME:Ayatana, then we skip this process (running this
package dependencies through SUSE Security Team).

Here’s how it looks the current stack of indicators (there’s a couple more packaged,
but I’m not using them at the moment, ex: nm-applet patched, indicator-network and
friends).

Within the next days, I will I will make a 1 click installer and run a BETA phase for
the Indicators/GNOME2.

It’s been a while and there was nothing special to report, KDE SC 4.5 just worked. In
the meantime KDE SC 4.6 was released and openSUSE offers it in KDF as well as KR46 repos. Big
thanks to everybody who is involved in establishing and maintaining those repos – openSUSE
really profits a lot from the (openSUSE-)KDE community that makes it possible to provide
such a nice and updated KDE distro.

Those updating from KDE 4.4 which came with openSUSE 11.3 to 4.6 – please save your
plasma* files from ~/.kde4/share/config in case plasma crashes after the update.
Submitting them to Novell’s bugzilla would be much appreciated in order to get those
crashes fixed for openSUSE 11.4. The same applies to all other issues that come up when
updating KDE 4.4 to 4.6, e.g. kdepim-related.

KDE SC 4.6

KDE 4.6 has some nice fixes, among them bko
bug 163707 which prevented KDE from restoring the resolution set in
systemsettings on login. This is especially important to openSUSE users since sax2 is gone
and display settings moved into the desktop environment. Plasma seems to become more
stable with every release – in fact I did not have any major issues with it since ages and
bug fixing is pretty fast as well. Dolphin does also not suffer from buggy dbus packages
anymore and with the latest strigi packages I do not encounter any crashes on close or
when hovering certain files which did crash dolphin before. Thanks to remur_030 who helped
the strigi people tracking the latter down for .msi files and thereby found and fixed some
general issue in strigi which could cause crashes.

Desktop search

The desktop search does still not justify its name though since basics are still
missing, e.g. context given for search results as all other desktop searches do and kerry
+ beagle already did years ago. The feature was shown some months ago but is not as such available in KDE 4.6 –
thus even in KDE 4.6 all the user gets is a replacement of kfind + tagging which needs a
huge database for that simple task.

On top of that there are still issues with virtuoso-t hogging the CPU,
its database never decreasing in size but only increasing, even if you remove folders from
the “to be indexed”-list and the systray-tool used to suspend the indexing vanished as
well decreasing transparency to the user of an app which potentially keeps your hard disk
and CPU busy.

Yes, I know there is always a shortage of manpower but IMHO if an app fails to provide
the very basic features regarding the functionality its name advertises, it will not gain
any acceptance among users and since every xth user is also a developer it will not
attract developers either. Thus the extent of this manpower shortage is self-imposed in
case of nepomuk aka desktop search.

I think its a bit unfortunate that strigi is always blamed for anything related to the
desktop search in KDE although it is just the tool that is used by nepomuk and its usage
is up to nepomuk and not strigi itself, i.e. when to start hammering the hard disk, how to
handle the results within a database, what results to display when searching, giving the
user control and information regarding its activities etc. From my experience strigi devs
are quite responsive regarding bugs and questions – although their websites are all pretty
much outdated. :)

For openSUSE 11.4 there is still one major mystery bug to solve for openSUSE 32-bit
NVIDIA users which get several
apps crashing since they updated to KDE >= 4.5.

Power-management

Power-management got worse in KDE 4.6, regressions such as not disabling
powermanagement on desktops and thus suspending the display every 10 minutes, the
brigtness slider not representing 100% of the brightness supported by the notebook and it
still messes with the brightness the user has set. All these were reported some weeks ago
already. Let’s hope that KDE SC 4.6.1 fixes those since that seems to be the version that
openSUSE 11.4 will ship.

Further having a presentation-scheme (no suspend, no dimming etc.) is kind of useless
with KDE 4.6 since it will change to the next scheme if the battery hits any limit. Thus
you have to permanently watch the status and switch back to the presentation-scheme to be
save of a suspending notebook while you watch a movie within the presentation or during
some longer discussion which leads to you not moving the mouse for some minutes.

Ignoring the scheme the user manually set does indeed make sense but only for the last
5% of your battery and in order to avoid the notebook just turning off because there was
no power left.

openSUSE 11.4 milestones also features a powermanagement bug that makes your hard disk
suspend every few minutes, confirmed but no fix so far.

Package-management

For openSUSE 11.4 we are currently testing
kpackagekit/apper as a replacement for the unmaintained kupdateapplet.
Kpackagekit works ok but it seems that its zypper backend could need some improvements.
And the next version of kpackagekit which will be called apper features monochrome systray
icons which is fine, but the “security patch available” signal is just a tiny red dot
which is hardly visible, especially if your eye-sight is not the best or you are suffering
red-green colour blindness. So most issues with kpackagekit are not actually kpackagekit’s
fault but either backend-related or touching artists’ taste.

Phonon-backends

Another application to test is the
phonon-backend to be used in openSUSE 11.4 by default. Should we stay with xine
whose backend is apparently unmaintained but has served most users well, switch to the
vlc-backend or maybe use the gstreamer-backend?

Trying to play some file with amarok and the gstreamer-backend brings up some dialogue
(/usr/lib/gst-install-plugins-helper) that asks whether it should search for some package,
I guess codecs. If one clicks on “search” kpackagekit opens up and claims instantly that
“Getting what provides” finished but does not do anything. This is on 11.3 plus KDE 4.6
from KDF, so let’s hope it works better on 11.4.

The vlc-backend consumes the double amount of CPU for playing the same mp3 via amarok.
8% instead of 4% might not be that much in absolute terms but a 100% waste nonetheless and
especially on mobile devices everything that wastes battery should be avoided. Further
there seem to be issues playing video via vlc, some apps like dragonplayer.

KDE-PIM

And finally there is of course the always present issue of KDE-PIM. openSUSE 11.4 will
ship kdepim 4.4.10 which needs testing. There is especially one annoying bug which makes kontact
crash when logging in if the last view before logging out was kmail. So let’s
hope this can be fixed before 11.4 gets released.

I was really looking forward to KDE-PIM 4.6 since IMAP-support seems a lot better with
akonadi, at least for my use-cases which include suspending/resuming. The latter makes
KDE-PIM 4.4's imap slave fail and not recover which works fine with KDE-PIM 4.6. You can
get regularly updated packages for the latter off openSUSE’s UNSTABLE KDE repo.

Help testing

Please help testing KDE SC 4.6 from the openSUSE repos in order to make it shine in
openSUSE 11.4. Feedback can go to the related wiki pages or straight to
opensuse-kde@.

Features with highest vote, but no one has been assigned to yet.

“Network installation could be improved by running package download and package
installation in parallel.”

“I wanted to open a fate feature about this when I first heard of plymouth, but
reading

http://fedoramagazine.wordpress.com/2008/10/21/interview-fedora-10s-better-startup/

really makes me think we should go this way.

Ray’s comment starting with “Every flicker and mode change in the boot
process takes away from the whole experience.” is especially interesting. Is it
okay to track the “don’t show grub by default” here?”

“An easy way to remove Software!

For example: you installed an application with “1-click install” (which
will install all the packages that you need), there should be an easy way (also with 1
click) to remove what you have installed with that 1-click operation… in another
words: an “1-click Uninstall” to remove installed software (dependencies and
packages included).”

“We need a replacement for sax2 in 11.3, as a safety measure for when auto
configuration fails to detect certain monitors/keyboards/mice. (…)”

“We need a feedback about packages that are preferred by users and actively
used. Debian already has a tool named Popularity contest (popcon) (…)”

“Idea from community member Raúl García. Same concept as MSI packages for
Windows but exploiting the One Click Install concept of openSUSE (and therefore
inheriting the simplicity, code and security. (…)”

“The YaST Qt package manager should provide as much information in the
“Installation Summary” view as zypper, esp the overall download size to expect
and how much disk space will be freed/used after performing the operation.”

“The YaST2 sw_single dialog for conflicts, vendor change, architecture change
etc. is very scary for many users.

The dialog asks the user to select one of usually three offered solutions for each
problem without giving much help. This is a cause for many complaints, and contributes
to myths of RPM dependency hell still existing today. (…)”

pypy is (almost) fully compatible to python 2.5 but it can execute your unmodified
Python code 5-15 times faster than the standard cPython.

For benefits see here: http://fedoraproject.org/wiki/Features/PyPyStack

It takes more than 1 hour to build on a fast machine ….so providing a nice rpm
package would make sense

pypy has been around for a very long time but only now it has a 64 bit JIT
compiler

openSuSE distributes the package wodim instead of the package cdrtools. The reason
this happens is a claim of the Debian maintainers that the present license of the
package cdrtools is incompatible with GPL.

However, even if it were the case, it does not make a good reason to exclude
cdrtools from openSuSE.

Broadcom has released opensource drivers for some of new Wireless cards. That
could be nice to get those cards working out of box in opensuse 11.4 for snupported

The Testing Core Team IRC meeting was held Jan. 31, 2011 at 18:00 UTC. The next one
will be on the Monday following the release of 11.4 RC1 at 18:00 UTC.

In our meeting, we discussed our experiences with 11.4 M6 and discussed bugs that we
have encountered. We also discussed how to improve the openQA testing to catch problems
that would interfere with installation; however, this will always be problematic. For
example, the x86_64 DVD from Build 1034 turned out to be too large to burn to a standard
single-layer DVD. At the time of the decision to release that buid as 11.4 M6, the testing
process was working on Build 1033, which did not have this problem.

My personal set of bugs were mostly due yo problems with software other than 11.4 M6.
The NET install CD failed to boot after installation on a VirtualBox VM, but the KDE Live
CD installed OK on that same VM. The problem was with VirtualBox 4.0.0 (4.0.2 works fine).
I also have one system that uses the i915 graphics driver that boots with a garbled
screen, but it works with the “nomodeset” boot option. That is a kernel problem, not with
openSUSE 11.4 and the bug report was placed at http://bugzilla.kernel.org..

It is extremely important to test M6 so that as many bugs as possible are found and
fixed. Remember that your hardware may have problems not seen by other testers. Remember
that it is essential to report the bugs, otherwise thay may not be fixed by the final
release of 11.4.

Annoncing the first virtual launch party

Dear folk, we are organizing a special event for the openSUSE 11.4 launch, and you’re
invited. Virtually all of you can participate, and increase the success of it. And spend a
good time.

Too soon? Not really, we are in the process to organize also pre-release party, certainly
for the RC1 and RC2 launch. So you can practice before the real event. Prepare your
environment, and dress your avatars with decent clothes, and gadgets.

We will do our best to welcome you in english, french & greek.

If you want you can also anwser our short pool we are looking about help.

Where?

On secondlife.com, go to area macedonia. at 183,213,21 coordinates Or fire the search
engine, and look after Geekos group, then join that group

When?

During 3 days March 9 10 & 11 2011 Party start at 16:00 UTC ( 8am SL time)

What?

Join our special place build for that event and let’s get

Dance party

Free drink

Goodies

Wall of pictures

11.4 installations movies

open minded discussions

Experience exchange

Who?

Your guests would be myself (tigerfoot) & Morgane Marquis. A team of excellent dj’s as
Lillith from Australia, Esquievel from USA, Stefanos from France, or our great Greeks
neighbors.

Why?

Hey not so long ago I was kicked by H! Because it’s a place where people have also fun, and we want to talk with them
about the freedom & openSUSE. Did you never attempt to realize something that has not been
made yet? Just to have a lot of fun! The full explanation Here.

How?

To access that 3D virtual world, you need a recent computer 1.5Ghz or +, and good internet
access >3500/300bps, and a 3D enabled graphics cards like radeon HD4xxx or more, Nvidia
Geforce >9600, Intel > i945 & Intel Extreme.

To be continued

In the next weeks, I will publish an more technical article about how to get 3D world
viewer installed on your openSUSE. And we are just finishing the picture gallery about that
project which should be online next week (due to FOSDEM) this week-end.

Stay tuned !

The openSUSE Weekly News are available as livestream or podcast in German. You can hear it
or download it on Radiotux.

Shortly after the OpenStack “bexar”
(spoken “bear”) release was ready, my packages finished building and are available at the
isv:B1-Systems:OpenStack Build Service repo.

Grab them, while they are still hot!

The ride might still be a bit bumpy as the whole OpenStack development is very Ubuntu
centric, and thus some of the dependencies, especially to old versions of python stuff are
tricky to find. However, first results look promising.

I’ll update here soon with some short hints on how to configure and use the whole lot.

Thanks go to my colleagues Christian Berendt and Andre Nähring at B1 Systems GmbH who have
been tireless in testing packages and reporting packaging bugs and other problems. Thanks also
to Gregory Haskins with whom I started the packaging effort early in december.

Future distributions will use a consistent, predictable scheme to
name network interfaces, using names such as “em1? and “pci2#1? instead of “eth0? and “eth1?
to provide more transparency for server administrators. As various new kernels have recently
been introduced, the Kernel Log will provide an overview of the most important Stable and
Longterm kernel series.

For
years, Matt Domsch has advocated solutions which provide reliable and predictable
network port names – in systems with multiple network sockets, the driver loading sequence and
hardware response times influence whether a certain port will be called eth0 or eth1. Now, the
Dell technology strategist and DKMS contributor seems to have taken a big step towards his
goal. On his blog, Domsch, who also
contributes to the Fedora project, explains that Fedora 15 – expected in May – will use a
device naming scheme that he helped develop, in which udev accesses “biosdevname”, a program
mainly developed by Dell employees, to allocate network device names. The developer says that
other distributions are also likely to adopt this solution.

This naming scheme will make udev allocate the device name “em1” to the
motherboard’s first network port, “em” being short for “embedded”;
network cards will be named according to the pattern “pci#
(such as pci2#1), which should always make the ports on a network card accessible under the
same name as long as the card, or a substitute, is inserted in the same slot. The
sub-functions of network cards that can be partitioned (NPAR) and the sub-functions of cards
with SR-IOV virtualisation support are given an added underscore and a number. As before, vlan
functions are separated by a dot, and aliases by a colon.

When allocating names, biosdevname accesses the information available in PCI firmware
specification 3.1; if this information is unavailable, it will try to retrieve values using
smbios. This is designed to match the numbers behind the “em” with those printed
on the housing or board – and considerably help network admins with their cabling, especially
on servers with a large number of network sockets. If biosdevname can’t retrieve any
information this way, the program uses the PCI IRQ routing table and will allocate the numbers
according to the card’s position in the device hierarchy. Biosdevname doesn’t handle USB
network interfaces, which will continue to be given such names as “eth0”.

Recently, I ran into an rp_filter change for all Kernels after 2.6.31. So read along for
an explanation of both the sysctl change and a practical example of rp_filter usage.

Lets say you had the following entry in your
/etc/sysctl.conf

net.ipv4.conf.all.rp_filter = 1

with the intention of turning on reverse path filtering for all interfaces. Well you didn’t get your wish- rp_filter
remained disabled if you are running a Kernel older than 2.6.31.

This could come as a suprise if you upgrade your Kernel and have a system relying on
rp_filter being disabled or enabled (e.g. multicast routing, multi-homed servers). If you have
a single-homed unicast server setups this change will probably go unnoticed however.

The fix was implemented upstream in v2.6.31 and the basic issue was that each individual interface has an rp_filter
setting which defaulted to 0 and the interface setting overrides the “all interface setting”
since they were AND’d together.

Takeaway: Once you begin to know your way around the LibreOffice suite, you can add a
few advanced techniques to your repertoire. Jack Wallen offers five tips to get you started.

In a recent post, I introduced LibreOffice and shared some pointers to help ease the
transition from Microsoft Office to this newly forked piece of software. After you get your
bearings with these tools, you may want to expand your LibreOffice prowess and become a
power user. How do you do that? You learn some advanced techniques. Here are five tricks
that will get you up to power-user speed fairly quickly. (…)

The script command is part of the util-linux-ng package
and so should be available already installed in any distribution, or you should be able to
easily add it.

What’s script ?

From his man page:

“Script makes a typescript of everything printed on your terminal. It is useful for
students who need a hardcopy record of an interactive session as proof of an assignment, as
the type script file can be printed out later with lpr.” (…)

The read command is designed to read and then use in the script input from the user. The
input that is provided by the user is stored as a variable. This is a builtin variable that
will store one line of input from the user in one or more variables. The read command is
valuable as it is a major way to input information into a shell script. Lines are read into
the script with standard input and split via the $IFS variable. This stands for internal
field separator. The first word is assigned the first variable, the second word the second
variable, etc. (…)

video series. In this first episode, Chris L. Bennett demonstrates how to create a
traditional Hello World application. (…)

By a very definition, it seems that working for the Linux desktop is like shooting darts
in the dark. Obviously, one would not be able to see where the dart goes, neither if you are
hitting the target. However you are definitively hitting something, but you do not seem to
know what.

In comparison, the Linux desktop aiming at the end user seems to fall under this category.
The bigger question will always be, who are we trying to satisfy through our Linux product?
Given the vastness of reach that Linux has on thousands of coders, the Linux desktop project
is bound to receive a great array of views, ideas and currents of thought that will lead the
Linux desktop from one place to the other. Believing that coming together in order to work on
a particular project is hard for me. However, projects such as KDE 4 have shown great strength
in coming together and creating something revolutionary and beautiful. Other efforts to make
the Linux desktop a reality have also come together in order to create similar results to what
KDE did. Gnome has followed in the footsteps of KDE and has also gathered its
community-enthusiasts and created the new Gnome 3 iteration.

However, the Linux desktop is still immature–I do not say this with malice–in the sense
that projects that aim towards a goal seem to center their understanding of what the Linux
desktop is in a less opened environment to which they could gather to and understand what it
is that simple, non-tech savy people understand about the way we have made their graphical
environments. I am referring to what the voice of users has to say about the way THEY use
their computers as opposed to what we Linux Desktop thinkers believe is good for them.

For example, if I am not mistaken, KDE 4 was an aim that grew deep in the KDE community
overtime, believing that their product KDE 3 was outdated and needed to be revamped. All over
the internet there were calls for change and some even ventured to creating new ideas about
the way KDE 4 was going to be. I remember seeing new icons at the Oxygen Icons website which
promised to deliver a new way of interaction with the desktop through their plasma desktop. I
was dazzled by the beautiful icons created in order to show the newness of approach that KDE 4
was going to take. It took icons to make people excited over the project. Gnome followed a
similar path. Seeing that KDE 4 has so drastically changed the aspect of its default desktop,
it decided to launch their newest major revision, Gnome 3. Their approach came from
often-unloved Gnome Shell. Brainstormers created a new way to interact with the desktop based
on a combination of very active desktops and windows as well as an ease of access to files and
applications.

While all this speaks to the minds of users that projects such as Gnome and KDE did their
best in adapting to changing times, the old problem also became apparent. The community effort
derived into personal effort, which in turn made it seem as if these projects were put on the
shoulders of the few who could make ideas come true through their code as opposed to asking
the people, like the rest of us, what WE think of their creation. I am a document developer,
and I do not appreciate it when people tell me that my earnest efforts do not fit their life.
I become unhappy and probably bitter since all my work was worth nothing in the eyes of users.
But alas, this is something that happens in man development teams. It is part of the process
to let a rough stone roll down the hill until it becomes smooth. However, efforts coming from
KDE and Gnome, although being amazingly written do not seem to tackle non-tech users as well
as it does for them, why? because the rest of us are unable to code but they are. We do not
have a voice because no one asks us what we think.

Did KDE 4 and Gnome 3 ever conducted surveys to people in order to understand their
interaction with computers? Do these two projects ever reach out to the community (non Linux
users) in order to find out their needs? If they did, it was little. I hereby advocate a
stronger case for the unheard, for the ones who will be placed these great tools in our hands.
To these two amazing projects I say, be great listeners, seek out opportunities to understand
the rest of us. Do not be like the people in this video giving out a Christmas present that
only fits some.

Let’s shoot our darts with the lights on. :D

When I was last time in Germany, Leinir told me about an event called Global Game Jam. I
liked its idea very much – 48-hour game coding marathon. I was amused when a couple of days
later (just one day before the event took place) my friends Split, Lokiman and Frem told me
about the Prague chapter called Game Jam Prague and invited me to join them. We decided to go
there under the name they already used for a couple of their projects – Hyperbolic Magnetism
aka @hypmag.

The event started on Friday evening. When we arrived, the place was already full of other
teams preparing their stuff. This was very different from other (mostly open-source related)
events I attend where I usually know at least a few people. Here, I knew no one except my
team! :-) At around 6pm we were given a topic that should be somehow present in our game –
Extinction. I was very surprised that we were able to brainstorm over 15 ideas in less than
half an hour. Later we discarded most of them (because they were too obvious or too complex)
and we ended up with two.

We agreed that for idea one to be successful we would need to create nice graphics and
because none of us was confident enough, we decided to pick the another one where simple
graphics would suffice. So we started to work on a game with the working title “Nations”. The
idea was really simple: you have a couple of nations, represented by triangles (people) moving
inside the circle (border). Each nation expands in time and when the circles start to overlap,
triangles inside the intersection start to fight together. Moreover, if the nation is big
enough, it starts to produce A-bombs which are then launched at other nations. Your task is to
maintain balance between the nations, so none of them is completely destroyed. This is
achieved by applying positive or negative force on some places of the game area. Positive
force causes affected triangles to reproduce more, negative force causes the affected
triangles to disappear. We implemented basic behaviour of the game mechanics and went to sleep
on Saturday morning.

We met again on Saturday evening and we coded and tweaked and coded and tweaked … It was a
long way, but at some point (I guess it must have been something around Sunday 4AM) we
realised we want to change the whole game logic completely. How about we had only two types of
nations – green controlled by the user and cyan ones by AI? What if player could decide to
split the nation into two halves or join two nations into a bigger one? Bigger nation of
course produces A-bombs faster, but is also easier to target. We replaced most of the code and
I started to work on an AI, which suddenly became necessary. We worked until Sunday noon when
we were finally satisfied with the result. In the meanwhile Split composed a great music track
and we quickly hacked game menu, intro screen and other cosmetic stuff. That’s how it looked
in the end:

I’ll attach the gameplay video to give you even better idea how the game is played:

Youtube

At the end of the event all contestants judged the produced games and the first three
places were announced – check the list for all other games and the result. The first team also
got a very nice pacman-themed cake (which was also very tasty, thanks for sharing!). Although
we didn’t make it into the Top 3, I think it was a great success for us. We tried something
completely new and we also met a lot of interesting people (one of them being Antonin, author
of the legendary TotalFinder). I also hope that we’d be able to finish the game and publish it
into Apple App Store (and probably later into Android Market).

Finally I present you the photo of amazing Hyperbolic Magnetism shortly after we submitted
our game at the end of the 48-hour session. :-)

See you next year!

openSUSE has a release cycle of 8 months, i.e. a new version every eight months, and each version is supported for 24 months. There are numerous reasons to have it this way, but there are equally numerous situations where one would like to have an LTS (Long Term Support) version, like servers. This thread shows the demand is there for at least some of us. It also appears that some efforts to come to an LTS version of openSUSE have already been made.

A returning issue: problems in another OS require the use of install media, which causes loss of the bootloader, that manages booting the installed operating systems, so no openSUSE. This user had a crash in XP, that made him land in a continuous loop, with no OS available at all. This one is not solved yet, but it’s going there…

From the title an insider would expect an openSUSE Factory or openSUSE 11.4 Milestone 5 user, since those have kernel 2.6.37. Neither of those is true, the kernel was installed from a repo, that was added during a one-click procedure from a non-supported repo. Read how this is found out by the thread starter and the other contributors.

This is the place in the forums where people ask for things like hardware advice, open source software equivalents for proprietary ones, community members’ thoughts on their plans, or “will openSUSE run well on my ….”. Sometimes the replies are quite straight forward, other times we see lively discussions.

Several developers approached me and asked for more time to port their applications. So
we extend the deadline of the contest to 31. of march. Everybody has one more month to port
a KDE or Qt application to Symbian or MeeGo. Remember that you can win 10.000,- so please
consider to make your KDE or Qt application ready for mobile.

You find more informatiuon in the original contest announcement: http://blog.karlitschek.de/2010/12/qtest-mobile-app-port-contest-launched.html

Please make sure that you also provide binaries for you applications. This makes is a
lot easier for the jury to test you application. Have fun and good luck.

Yesterday our vigilant operations guys detected a targeted attack against some of our
developer infrastructure. The attack resulted in an exploit of several SourceForge.net
servers, and we have proactively shut down a handful of developer centric services to
safeguard data and protect the majority of our services.

Our immediate priorities are to prevent further exposure and ensure data integrity.
We’ve had all hands on deck working on identifying the exploit vector or vectors,
eliminating them, and are now focusing on verifying data integrity and restoring the
impacted services.

The problem was initially discovered on the servers that host CVS but our analysis
indicates that several other machines were involved, and while we believe we’ve determined
the extent of the attack, we are verifying all of our other services and data.

As a short term response, we’ve taken down the following services to prevent any
possible escalation:

CVS Hosting

ViewVC (web based code browsing)

New Release upload capability

Interactive Shell services

Once the immediate response to this attack is over, we will be providing a much more
detailed account of what’s happened, and what specific actions we are taking to prevent
further exploits.

Despite earlier reports that very few if any new features would likely be seen in The
Document Foundation’s first LibreOffice release, the influx of new developers allowed
much more work to be done. In fact, it was even released ahead of schedule. So, what kind of
new goodies might one find? (…)

Recent meetings held among the RedHat, Fedora, Debian, Ubuntu, OpenSUSE, Mandriva, and
Mageia communities has resulted in an informal agreement on an architecture for a common app
installer API. Yet the dream of a universal GNU/Linux app-store may be much farther off.

Word of the app-installer meetings at OpenSUSE’s Nuremberg, Germany, offices
earlier this month emerged last week in a blog
post by OpenDesktop.org’s Frank Karlitschek on Jan. 24. This was followed by
a more detailed Jan. 26 report on the meetings by Swapnil Bhartiya in Muktware.

On Jan. 31, LinuxInsider’s Katherine Noyes sampled the Linux blogs and forums for feedback, and found general support for a
common app installer, but with plenty of observers predicting doom for the project. The more
distant dream of a common app-store for Linux, which was not formally discussed at the main
Nuremberg meetings, seemed even more far-fetched to many, though many others deem it a
worthy goal.

Having a common installer — and ultimately, a universal app store — should help
attract new users and third-party developers to desktop Linux, goes the general consensus.
It would help to cushion the fragmentation of the desktop Linux market while easing the pain
of dealing with the complexity of most package managers. Yet, many other attempts at unified
standards among Linux communities have ended in failure, note skeptics.

It was quite a day for Sony portable fans. Earlier today (well, technically yesterday)
Engadget posted about some hands-on experience with the Xperia Play, aka the
Playstation Phone. It sure looks real to me. Engadget is being coy about where this unit
came from but post author Richard Lai says he’s been using it as his primary phone for
a few days now, with generally good results.

No ‘official’ games are available for it, but Lai loaded up some emulators and
mapped the hardware buttons to emulator controls and had a go. This isn’t final
hardware but for an early look it seems promising enough. (…)

IPv4 is dead. Long Live IPv6.

Early this morning, the Asia Pacific Network Information Centre (APNIC) announced that
it had been allocated two /8 address blocks from the Internet Assigned Numbers Authority
(IANA ). Those two blocks,
39/8 and 106/8, were the last unallocated blocks in the IANA free pool of IPv4 address
available to Regional Internet Registries (RIR). With the allocation, the final days of IPv4
have moved closer as the number of available addresses that can be allocated will dwindle.

On January 26th of this year, KDE
released version 4.6.0 of its Plasma Workspaces, Applications, and Development
Platform. While many major versions of KDE have focused on features, 4.5 was mostly a
stabilizing release, fixing thousands of bugs. The 4.6 release is all about polish. It is
the icing on the cake for KDE 4, adding speed, visual enhancements, and increased hardware
compatibility.

Faceted Browsing for Dolphin – Pressing Ctrl+F in
Dolphin used to open Kfind, a search interface that used various Linux/Unix search tools
such as “find” and “locate” to get you the files you wanted. In KDE 4.6, you can open the
search interface within Dolphin and find indexed files quickly and easily. The addition of a
filter side bar also allows you to find exactly the types of files you want, giving you
options for file type, creation date, and even rating. (…)

In my previous report about journaling filesystem benchmarking using dbench, I observed
that a properly-tuned system using XFS, with the deadline I/O scheduler, beat both Linux’s
ext3 and IBM’s JFS. A lot has changed in the three years since I posted that report, so it’s
time to do a new round of tests. Many bug fixes, improved kernel lock management, and two
new filesystem (btrfs and ext4) bring some new configurations to test.

Once again, I’ll provide raw numbers, but the emphasis of this report lies in the
relative performance of the filesystems under various loads and configurations. To this end,
I have normalized the charted data, and eliminated the raw numbers on the Y-axes. Those who
wish to run similar tests on their own systems can download a tarball containing the testing
scripts; I’ll provide the link to the tarball at the end of this report. (…)

I’m usually big on milestones — anniversaries, birthdays, holidays, etc. But it wasn’t
until I was going to bed last night that it hit me: It’s been a year since I left Novell and
started working for myself full-time. Here’s how it’s going so far… (read on if you’re
interested, but this is mostly full of personal stuff so feel free to skip down to some of
the more interesting stuff on technology if you like…)

My last day with Novell was January 31st, 2010. Pretty much exactly two years after I
started with the company (February 1st, 2008). I put in notice about two weeks before that,
but had been considering quitting long before. I’m not going to go into a lot of backstory
here, but the long and short of it was that after two years the job was not what I wanted to
be doing. Some jobs you can do whether your heart is in them or not (I worked at a car seat
factory for three and a half years, and I don’t think my heart was ever in that…), but
community management is something that you need to be all-in for. (…)

On September 28, 2010, LibreOffice was announced as a fork of the OpenOffice.org office
suite. In the weeks since then, there have been promises of innovation and change from
LibreOffice, and an attempt at dignified silence from OpenOffice.org.

However, it was only last week that the two rivals released their 3.3 versions, and
users had the chance to see whether the differences in the culture of the projects made any
difference in the code. (…)

It’s been nearly a year since the last major release of Firefox — version 3.6 — and
development of the Firefox 4 seems to have slowed down a bit, with the planned release of
late 2010 getting set back to February 2011.

Much of this development has been wrapped up in adding HTML 5 features to the open
source browser, so the delay, while not greeted with much enthusiasm amongst Firefox users,
hasn’t created a lot of fussing, either.

Nor has it slowed down the development of the vast array of extensions available for
Firefox, as developers find new and creative ways to view and interact with the web every
day. Extensions are one of Firefox’s most powerful feature sets, since their ease-of-use and
extensibility enables users to build exactly the kind of browser they need. With more than
5,000 add-ons available, there’s a lot of customization options to chose from, and some of
them have to be better than others.

So, which ones do you simply need to have? That will be the focus of this series, which
will review the best Firefox extensions in several categories, then round up the most
popular Firefox extensions of all as of the end of 2010. The categories are built around
Mozilla’s own classifications, but grouped together in ways we think makes more sense.
