Hi all,

Won't say much (look at my mailer ;-)
Try to get signal-to-noise back on track after this!

Although Mac OS X is based on the mach microkernel, the BSD kernel layer is
compiled into the same address-space as the microkernel, thus creating a
mixture between a true micro-kernel and a monolithical kernel. At the same
time the messages and ports from mach are still available. Mixing the BSD
kernel layer with the mach layer may not be wise (if you separate them BSD
may crash, without affecting the mach layer, here they can both go down).
But the Mach layer provides very little support for the rest of the system,
most of that is done by the BSD layer, which means to the end-user that
there is no difference between bsd going down and a complete systems
failure. The speed improvements are bigger than the theoretical increase in
I have yet to crash Mac OS X

The development system under OS X is beautiful. Every Linux developer
should take a look at it, since the tools behind them really are the
familiar gcc and gdb (and a few more, make or jam, ...). The interface is
well ddesigned, largely without manual you can write and debug you
command-line tools. The interfacebuilder is great, although a manual would
be nice there (Still learning)

Interfacebuilder is really nice, because it ties in with the rest of the
developement system so well: you draw you interface and the code needed to
support it is there, precompiled in the objects. Adding your own support
logic is easy, interfacebuileder writes the templates you have to fill out.

I have yet to master the 5-minute-wordprocessor-with-spell-checking-demo.

As 'MacWorld' put it: (

You know there's revolution in the air when the following can be typed into
an operating system built in Cupertino and execute flawlessly:

dig @ axfr | grep '^c....*A' | \
sort | cut -b5-36 | perl -e 'while(<>){print pack("H32",$_)}' |
gzip -d

Put that in your GUI and smoke it.

BTW: has anyone an idea what on earth this does?

Don't hold your breath, they actually make money from their hardware.
