NVIDIA's Optimus multi-GPU technology now works under Linux. Well, at least for some notebooks, it's been hacked together by an open-source developer and in fact is working to use both Intel and NVIDIA graphics processors simultaneously with the respective drivers. This is the best Linux implementation we've seen yet with NVIDIA Corp still not announcing plans to officially support this technology under non-Microsoft operating systems...

Administrate Databases Over the Web With phpMyAdmin

  • PCWorld; By Gabe Gralla, (Posted by bob on Apr 24, 2011 11:13 AM EST)
  • Story Type: Tutorial
PhpMyAdmin is the one of the most popular tools for MySQL database administration. A major reason for this is its portability--phpMyAdmin runs in a Web browser, so you can access it from almost any computer. The program is also robust; phpMyAdmin has enough functionality that you can probably create and run a Web site without knowing any SQL. Being free and open-source never hurt anybody, either.

The Tests Showing Ubuntu 11.04 On A Power Consumption Binge

Ubuntu 11.04 "Natty Narwhal" is set to be released on Thursday and while there are a number of new features to talk about in this latest release, the Phoronix Test Suite software has been busy analyzing the performance of this latest release. There is open-source graphics driver improvements leading to some performance improvements (such as Radeon KMS page-flipping), the famous ~200 line Linux kernel patch to improve responsiveness, and various other enhancements that catch our fancy in Ubuntu 11.04. However, one area where there is a frightening regression in Ubuntu 11.04 is with its power consumption. For mobile devices in many workloads, Ubuntu 11.04 is consuming noticeably more power than in any of the past Ubuntu Linux releases. Sadly, no one seems to have noticed in time since continuous integration testing on Linux seems to happen so haphazardly right now.

Mobile Users Beware: Linux Has Major Power Regression

For those that follow my personal Twitter feed will know that for the past week I've been closely testing Ubuntu 11.04 and all Ubuntu releases going back to Ubuntu 8.04 on many mobile devices in the office. The overall system performance, power consumption, and boot performance have been the principal targets. However, late this week I discovered a glaring regression: Ubuntu 11.04 is viciously going through power. Compared to Ubuntu 10.10, the power consumption on Ubuntu 11.04 for mobile devices is up about 10% on average but under some workloads, I am seeing the power consumption up by nearly 30%. This is happening on many mobile systems spanning multiple generations of Intel CPUs and with Intel / ATI / NVIDIA graphics. This issue has been tracked down to a frightening kernel regression in the mainline tree that is still not addressed.

Linux-based FROG-I robot thinks its a dinosaur

The Chinese Academy of Sciences demonstrated a quadruped robot intended to test gait control and locomotion -- and eventually mimic the movement of a triceratops. The flexibly jointed, 3.1-foot FROG-I robot runs Linux on an Intel Xscale PXA270 processor, communicating via Wi-Fi with a host computer, while lower-level functions are controlled by two Texas Instruments DSPs....
