12:00 AM - ROFL... linux bug in 2.6.15 and lower

commit 82c3c03a4096badd026c6e337f3c5dde020e9ec6

[PATCH] x86: check for online cpus before bringing them up

Bryce reported a bug wherein offlining CPU0 (on x86 box) and then
subsequently onlining it resulted in a lockup.

On x86, CPU0 is never offlined. The subsequent attempt to online CPU0
doesn't take that into account. It actually tries to bootup the already
booted CPU. Following patch fixes the problem (as acknowledged by Bryce).
Please consider for inclusion in 2.6.16.

Check if cpu is already online.

12:00 AM - back to the future GNU

powerpc: Fix problem with time going backwards

The recent changes to keep gettimeofday in sync with xtime had the side
effect that it was occasionally possible for the time reported by
gettimeofday to go back by a microsecond. There were two reasons:
(1) when we recalculated the offsets used by gettimeofday every 2^31
timebase ticks, we lost an accumulated fractional microsecond, and
(2) because the update is done some time after the notional start of
jiffy, if ntp is slowing the clock, it is possible to see time go backwards
when the timebase factor gets reduced.

This fixes it by (a) slowing the gettimeofday clock by about 1us in
2^31 timebase ticks (a factor of less than 1 in 3.7 million), and (b)
adjusting the timebase offsets in the rare case that the gettimeofday
result could possibly go backwards (i.e. when ntp is slowing the clock
and the timer interrupt is late). In this case the adjustment will
reduce to zero eventually because of (a).

12:00 AM - A comparison of Linux, Mac OS X, and Windows

http://lxer.com/lxer/story/56437/index.html

This article has a somewhat fair comparison, but of course the guy ignores a lot of other unix desktop replacements. Plus, OS X can replace UNIX in many cases since it is UNIX. :)

12:00 AM - Testing new JJ client

I'm working on the new Just Journal windows client. Its been about a month since I released a new version and there are certainly a number of bugs in the last version. Mostly this will be an interface improvement/bugfix release. Lets see what happens.

12:00 AM - bored

I'm quite bored at the moment. I've about had it with coding for today. On to another activity i suppose. On the up side, I may consider this client to be beta quality and release it. It will be considered 1.4. It certainly looks better than the last version.
