OpenSolaris Apps of Steel Challenge
Heres an interesting programming challenge for budding hackers (just follow this link) .
OpenSolaris is looking to beef up its packages repository and you can help. Submit the best entry and win a laptop!
Have fun and make a difference in the OpenSolaris community, while you're doing it! Takers, you may want to act fast, the contest lasts until May 8th. And I should add: dont forget to use Sun Studio compilers to get that extra performance boost from all the improvements made for all hardware upto the most recent one.

Dozen new World Records with Sun Studio + OpenSolaris at Nehalem Launch

Sun today launched x64 systems based on Intel Nehalem chip (aka Xeon Processor 5500 series) in grand style! Sun is calling these Open Network Systems to emphasize that its about much than just a chip upgrade alone. In particular, the message is around system design and innovation that encompasses " the convergence of open compute, storage, networking and software to deliver best application performance, simplicity and savings".
Application performance (and benchmarking performance) is best measured by what Sun highlighted today. Closer to (my)home, its a hit out of this park. Consider what the combination of Sun Studio 12 update 1 and OpenSolaris has cooked up:

• Best (World Record) SPECfp_rate2006, SPECfp_rate_base2006, SPECint_rate2006, SPECint_rate_base2006 performance
• Best (World Record) SPECompM2001, SPEcompL2001 x64 performance
• Best (World Record) SPECcpu performance on single-blade, workstation, and rackmount servers

All in all 13 World Records! Clearly what I would call game, set and match (Sorry about mixing up the sporting metaphors between baseball and tennis here).
You can find more performance briefs here. See here for a whitepaper on how Solaris optimizes for Nehalem.
This is a great chip to work on, and the Sun Studio team has done a wonderful job of delivering outstanding performance in utilizing its strengths.
Sun Studio 12 update 1 is currently in early access and you can join up to preview and take advantage of these performance benefits. Or you can get the same via Sun Studio Express 3/09, also currently available for downloads.
