New ‘Topdown’ UVM in NetBSD-Current

Andrew Brown has committed changes to -current implementing a new 'topdown' uvm. With these changes, the areas for heap growth and mmap(2)'ed allocations, which used to be separate, are now one and the same, allowing either one to grow much larger than before.

Review of KStars 0.9 under Mac OS X

They say the best things in life are free, and for UNIX computers, open source software certainly goes a long way towards proving that statement. KStars, a planetarium program written for UNIX machines running the K Desktop Environment, has been ported to OS X via Fink and X11, and offers Mac users a sophisticated but free planetarium program. Neale Monks takes a closer look at KStars and sees how it stacks against the shareware and commercial Mac OS planetarium programs. Not directly an OS news item, but definately of general interest especially for our geek readers. At the end of the article, you will find links to five more reviews of astronomy applications for the Mac.

J2EE vs .NET: Levelling the Playing Field

"It’s one of those rare situations where Microsoft is David, not Goliath; .NET is a displacement ploy targeted squarely against Java and J2EE, which has gained significant momentum amongst customers since its debut.
