What is Post-Link Optimization for Linux on POWER? Post-Link Optimization for Linux® on POWER™, also known as FDPR-Pro, is a performance-tuning utility used to improve the execution time and the real memory utilization of user-level application programs, based on their run-time profiles.

Last week we reported that the open-source ATI Linux driver had picked up improved power management in the form of dynamic power management and power management profiles that can be defined by the end-user.

In Q4'07 we had looked at Ubuntu's power consumption with all of their Linux releases going back to Ubuntu 5.04. While Linux has improved in recent years when it comes to power efficiency and optimizations, more processes running on the desktop had canceled out any real power improvements.

For some time I have been using the American Power Conversion (APC) uninterruptible power supply (UPS) daemon Apcupsd to interface my desktop computer with my APC Back-UPS ES 550.

Power management on computers has three parts: selecting devices that are more power-efficient, tuning your systems to run more efficiently, and configuring systems to use less power during periods of inactivity. Servers, desktop machines, and laptops usually need different power management schemes; there isn't a one-size-fits-all.

Nuvation announced a Power-over-Ethernet (PoE) IP camera reference design based on the Texas Instruments (TI) DaVinci-architecture TMS320DM365 system-on-chip (SoC). Nuvation's PoE-WDR DM365 design compresses real-time, full-color 720x480 (D1) video over Ethernet at up to 30fps, and incorporates a real-time Linux implementation, says the company.

What do you want your cell phone to be able to do? Massachusetts Institute of Technology professor Hal Abelson put that question to about 20 computer science students this semester when he gave them one assignment: Design a software program for cell phones that use Google Inc.'s upcoming Android mobile operating system.

PowerTOP is a Linux tool that finds the software component(s) that make your laptop use more power than necessary while it is idle. As of Linux kernel version 2.6.21, the kernel no longer has a fixed 1000Hz timer tick. This will (in theory) give a huge power savings because the CPU stays in low power mode for longer periods of time during system idle.
