Linux kernel 2.6.31 supports USB 3.0

You  might have read my post about USB 3.0 support in Linux. Though USB 3.0 is not yet out, the Linux kernel to be released during Labor day (September 7th) will support USB 3.0, according to The H-online. Changes to USB subsystem includes code to support USB 3.0 controllers with their Extensible Host Controller Interface (xHCI). There is no actual product available with USB 3.0. ASUS announced P6X58 motherboard with USB 3.0 support, but later canceled production due to lack of third party drivers.

The kernel also contains changes to Firewire code. The changes also include support for “IPv4 over IEEE 1394″ (networks via FireWire) in the more recent of the Linux kernel’s two FireWire stacks.

Defence spends $1.7m on ultimate Linux flight simulator

IT News reports that The Australian Defence Force (ADF) has revealed its latest flight simulator runs on Suse Linux-based clusters of Opteron servers and uses an open source graphics platform.

The Defence Science and Technology Organisation’s (DSTO) Air Operations Simulation Centre in Melbourne creates virtual words that allow pilots to experience real-world combat situations without leaving the ground.

According to a Defence spokesman, the simulator boots in about 30 seconds and uses a cluster of 4-core Opteron 2218 servers, with nVidia Quadro FX 5600G graphics cards. The avionics and aerodynamics simulations run on a number of 8-core Opteron systems.

All the nodes run Suse Linux. Unlike traditional Linux clusters, which focus on throughput, these systems are tuned for real-time performance – using features of the kernel such as memory locking, real-time scheduling and low-delay communication.

The visuals software was written in OpenGL using commercial and open-source scene graph engines and making “heavy use of OpenGL Shader Language programs” for creating effects such as clouds, smoke and vegetation.

Firefox crashes in Ubuntu while trying to watch Youtube in fullscreen

Posted 26 Aug 2009 — by Arun
Category Ubuntu

I had this problem only with Nvidia cards. I didn’t have this issue with ATI card in my laptop. Whenever I clicked the fullscreen box in youtube, firefox would crash. After I surfed through Ubuntu forum, I found a solution. This is what I did to fix the issue.

Depending on which version of Firefox you are using, the location of the file might change. If you are using the default Firefox that came with Ubuntu 9.04, the location most probably is /usr/lib/firefox. I have installed Firefox 3.5 and I’m using that, so my Firefox’s location was /usr/lib/firefox-3.5.2. All you have to do is open a terminal (Application -> Accessories -> Terminal) and type

sudo gedit /usr/lib/firefox-3.5.2/firefox.sh

If your Firefox’s location is /usr/lib/firefox, then type

sudo gedit /usr/lib/firefox/firefox.sh

Once the file is opened, add export LD_PRELOAD=/usr/lib/libGL.so.1 in the 2nd line. Leave the first line as it is. Your file should look something like below:

#!/bin/sh
export LD_PRELOAD=/usr/lib/libGL.so.1

# Firefox launcher containing a Profile migration helper for
# temporary profiles used during alpha and beta phases.
………………….

Save the file and exit the text editor. Restart Firefox (if it’s already open) and try it. It should work.

Racist Microsoft?

A photo on Microsoft’s website (Microsoft.com) shows three people (one Asian, one Black and one White) sitting around the conference table, but the company’s Polish website replaced the black guy’s face with that of a white man. The rest of the body was untouched. Microsoft apologized after criticism sparked across the online community. Here is the link to the photos.
