Unsung, Unpaid Coders Behind Federal IT Dashboard 99

theodp writes "The Federal CIO got a standing ovation for the new Federal IT Dashboard. Federal contractors got the cash. But sneak a peek at the 'customcode' directory behind the Dashboard, and you'll see that some individuals also helped bring it to life with their free software. For starters, there's Timothy Groves' Auto Suggest (Creative Commons License), Alf Magne Kalleland's Ajax Tooltip and Dynamic List (GNU Lesser General Public License), and Gregory Wild-Smith's Simple AJAX Code-Kit (SACK) (modified X11 License)."

Jeff Roberson Begins FreeBSD SMPng VFS Integration 54

A FreeBSD User writes "Jeff Roberson has announced that he has has begun integrating the Giant-lock free VFS code into the FreeBSD 6.x development tree. These changes will permit the UFS file system to run on multiple CPUs at a time on SMP systems (hyper-threaded, dual-core, or regular SMP), leading to substantially improved efficiency. It will also permit the VFS code to be fully preemptible on uni-processor systems, improving interrupt handling latency. With this change, almost all of the FreeBSD kernel is able to run fully threaded and in parallel on multiple CPUs with much less contention. He anticipates merging this work as an "opt-in" feature to the FreeBSD 5.x branch in the future. He indicates that the testing will be "opt-in", i.e., this change will not be fully enabled by default for the time being, and that it will take a while (a few hours) to complete the merge, so users of the 6-CURRENT branch may want to hold off updating for a few hours while he finishes the merge. The work was sponsored by Isilon Systems."
