Obsolete Microkernel Dooms Mac OS X to Lag Linux in Performance Disagreements exist about whether or not microkernels are good. It's easy to get the impression they're good because they were proposed as a refinement after monolithic kernels. Microkernels are mostly discredited now, however, because they have performance problems, and the benefits originally promised are a fantasy. The microkernel zealot believes that several cooperating system processes should take over the monolithic kernel's traditional jobs. These several system processes are isolated from each other with memory protection, and this is the supposed benefit.

24C3: Inside the Mac OS X Kernel Many buzzwords are associated with Mac OS X: Mach kernel, microkernel, FreeBSD kernel, C++, 64 bit, UNIX... and while all of these apply in some way, "XNU", the Mac OS X kernel is neither Mach, nor FreeBSD-based, it's not a microkernel, it's not written in C++ and it's not 64 bit - but it is UNIX... but just since recently. This talk intends to clear up the confusion by presenting details of the Mac OS X kernel architecture, its components Mach, BSD and I/O-Kit, what's so different and special about this design, and what the special strengths of it are. The talk first illustrates the history behind BSD and Mach, how NEXT combined these technologies in the 1980s, and how Apple extended them in the late 1990 after buying NEXT.

Kindle 3.X updater for Kindle 2 and Kindle DX released After a month and a half of testing thanks to the community of MobileRead, I can finally release the first stable version of the Kindle 3.X software updater (help me come up with a better name, please). If you haven’t read my last few Kindle-related posts (read them if you want more technical details of this script), you should know that this allows you to use all the cool new features of the Kindle 3 on a K2 or DX device. Installation is easy and is only three steps: 1) Use “prepare-kindle” script on old Kindle to back up and flash recovery kernel, 2) Copy generated files to Kindle 3 along with “create-updater” script and run it, 3) Copy generated update package back to old Kindle and restart. If that sounds confusing, don’t worry, the readme contains very detailed directions and even how to recover in case anything goes wrong. Here it is.

Stopping the Gears Last February, we let you know we were shifting our focus from Gears to HTML5. Over the last year or so, we’ve been working closely with other browser vendors and standards bodies to help define and standardize HTML5 features across browsers, and we’ve worked hard to improve these HTML5 capabilities in Chrome: We implemented support for application caches, which are a great replacement for Gears’ offline features. App caches are already being used by web apps like the NYTimes app in the Chrome Web Store.
