"The London Stock Exchange has said its new Linux-based system is delivering world record networking speed, with 126 microsecond trading times. The news comes ahead a major Linux-based switchover in twelve days, during which the open source system will replace Microsoft .Net technology on the group’s main stock exchange. The LSE had long been criticised on speed and reliability, grappling with trading speeds of several hundred microseconds. The record breaking times were measured on the LSE’s Turquoise smaller dark pool trading venue, where trades are conducted anonymously. That network switched over to Linux from Cinnober technology two weeks ago. Speed is crucial as more firms trade automatically at lightning speed, using advanced algorithms."

Linux 2.6.34 has been released. This version includes support for the Tilera architecture, a new filesystem notification interface called fanotify, a redesign of workqueues optimized for concurrency, CIFS local caching, support for Intel Intelligent Power Sharing in i3/5 systems, integration of the kernel debugger and KMS, inclusion of the AppArmor security system and several new drivers and small improvements. You can read the full changelog as well.

Well, this is quite interesting. This is one of those items where I have to make sure everybody realises I'm no developer as to not make myself look like an idiot. Having said that - LinSched. It's a user-space program that hosts the Linux kernel scheduler, so you can create and test scheduling policies on arbitrary hardware topologies - without actually having to work with the real hardware.

Ahem. I just had to write that all-caps headline. Broadcom's wireless chips - used by just about everybody in this industry - have been a major pain in the bum for Linux users, because the company did not release open source drivers. Workarounds had to be created, lots of pain was had in the process, but now, Broadcom has finally seen the light: they have open sourced their wireless Linux drivers.

Finally Bricsys has released the official version of Bricscad V10 for Linux. Linux users now have very capable desktop CAD software able to handle the DWG file format. From Bricscad website: "Bricsys is the first to release a .dwg based CAD software for Linux users. Bricsys NV, the developer of Bricscad, announced today that Bricscad V10 for Linux is now available. Bricscad V10 is the first .dwg based CAD platform available for the Linux Operating System. Bricscad V10, the leading alternative CAD platform for the .dwg file format, continues to offer freedom of choice to the CAD and Engineering community."

I came across a news entry at Phoronix about a new init replacement, systemd, and curiously started a read into the surprisingly heavy matter. Systemd is by no means as simple as upstart. It does far more things far more straight and in more detail. The differences are so significant that they enforce quite different configuration strategies. One can argue for both, depending on the goal to reach. However, that's not what I want to write about. After having read what systemd is capable of, and how it does it, I began to put the existence of all system daemons - in their today's forms - in question.

The 2.6.33 Linux kernel has introduced a useful new service called the DRBD - Distributed Replicated Block Device. This service mirrors an entire block device to another networked host during run time, permitting the development of high-availability clusters for block data. Explore the ideas behind the DRBD and its implementation in the Linux kernel.

As we mentioned in a previous article, Red Hat advocate Greg DeKoenigsberg claimed that due to the much larger amount of code it's contributed, Red Hat is a better open source citizen than Canonical, adding, "Canonical is a marketing organization masquerading as an engineering organization." A Computerworld blog retorts that that's no insult; and that marketing Linux could be just as important to the cause as contributing code. Updated

The latest panic in desktop Linux lad was that Dell would no longer be selling Ubuntu pre-installed on laptops and netbooks. Alas, for those who love drama, it wasn't true. In fact, Dell is expanding its Ubuntu desktop Linux offerings.

Some people hate the idea of adding proprietary software to their desktop Linux. For these people, there are Linux distributions such as gNewSense that use only free software. For the rest of us, who use distributions such as Fedora, openSUSE and Ubuntu, there are times we either want to, or feel forced to, add proprietary programs such as Adobe Flash or Skype or the ability to play proprietary audio and video formats such as MP3 or commercial DVDs to your Linux desktop. Here's how to do it.

The Linux Foundation, the nonprofit organization dedicated to accelerating the growth of Linux, announced the GENIVI Alliance (founded by BMW, GM, and others) has chosen MeeGo as the basis of its next reference release for In-Vehicle Infotainment (IVI). Also see this blog post.

Maverick Meerkat, the version of Ubuntu slated to be released later this year, brings with it several features and improvements that the Linux community has been eagerly looking forward to. I've taken a look at the blueprints for this next release, and picked out a few of the major items that Linux end-users will be interested in. Here are 5 things to look forward to in Ubuntu 10.10.

"The Portable Linux Apps project brings the ideal of "1 app, 1 file" to Linux. Applications are able to run on all major distributions irrespective of their packaging systems - everything the application needs to run is packaged up inside of it. There are no folders to extract, dependencies to install or commands to enter: "Just download, make executable, and run!"" A follow-up article describes how it works, and how to transform debian packages into AppImages. The packages don't include libraries, so the system won't need to update the same library in each individual app.

MeeGo is a Linux-based operating system designed by Intel and Nokia for netbooks and smart phones. Installing MeeGo on an Eee PC 1000 netbook is quick slick and easy. I found the user interface to be colourful and stylish with many quirky animations. MeeGo's features are easy to discover and it is fast and responsive.
