Intel is becoming more friendly towards linux (or at least is 
attempting to appear more friendly).  At OSCON, they (and IBM) 
mentioned several things that were of interest to the Linux crowd.

Powertop is a tool to see what's sucking power from your Linux laptop.  
From their promo, with the latest kernels (>2.6.21) and some tuning, 
laptops running Linux (with Intel CPUs of course) have the longest 
run times under battery.

Intel recently released their thread library 'Threading Building 
Blocks' under the GPL - a cross platform threads lib with a 
simultaneously released O'Reilly book on the subject.

IBM showed off the latest incarnation of the Open Source Eclipse 
development platform which now supports multiple languages quite 
deeply (C/C++, Python/Jython, as well as the native Java), with very 
deep views into the code.  They have recently released parallel 
programming plugins (MPI, OpenMP) as well as a module which 
integrates a number of profiling/optimization tools.  I'm just 
starting into it, which is somewhat intimidating due to the vastness 
of the options and the differences between the Eclipse IDE and the 
more standard unix build toolkit.  There were a number of people in 
the audience who had switched from the gnu toolchain to Eclipse and 
who said that once converted it would take wild horses to take them 
back (granted, a self-selected group).
