Mac OS X: Solaris Inside

WWDC prediction - hey, all the kids are doing it.

Solaris, Open Solaris.

Under Mac OS X. Briefly:

xnu/mach is really slow. Linux blows away OSX when threads are concerned. Solaris doesn’t have this problem
ZFS: Sun already announced that OSX will default to ZFS as its filesystem.
- This is a Solaris technology.
- Tested code is essential.
- Steve Jobs doesn’t let anybody else give away the biggies. Just ZFS is therefore a minor part of the announcement.
DTrace: Looking on the ADC site, there are WWDC sessions on DTrace, another Solaris techonology
Nexenta is Ubuntu on OpenSolaris - proof that you can skin a kernel
OpenSolaris to go GPL3. Jonathan Schwartz has said as much, assuming he likes the final license
Here is a picture from the WWDC lobby. A Sun is behind OSX. Game, set, match.

Hey, you must've seen something I missed on there. I still see DTrace listed here:

Yeah, except Schwartz appears to have pissed someone at Apple off as some of the Sun oriented sessions at WWDC have suddenly been taken off the agenda...
