delphij's Chaos

I have just tried to umount /usr on my test box in order to get all outstanding writes to be sync’ed to disk (as Kirk McKusick said, the umount system call will do true sync of a file system).

junsu has pointed out that gcc has the ablity to do profile, record the data and optimize the generated code according to the data. The nearest compiler guru I can visit is Prof. Husheng LIAO (sorry, the link here is not available to the Internet at the time writing, but this is hopefully to be changed soon) who recently concentrate his research in optimization for the Java Language Compiling process.

Further information will be available here soon.

With help from clement@, I have finally addressed the problem I am encounting was caused by a mix of libkse(libpthread) and its older version.

das@ [David Schultz] has done some benchmark of the different PID allocators recently being discussed on hackers@, and the result is available here.

As the FreeBSD 5.2.1 approaching its release day, I begun to think about the possiblity of having a personal customized release.

It’s not too hard for me, and also valuable because the FreeBSD Release Engineering Team has restricted the changes in a point release to be mainly “critical bugfixes only”.

Gibe is still the first place, and MyDoom(here, it was called Worm.SCO.A) drastically dropped down.

beastie# bzcat maillog.0.bz2 | grep INFECT | awk ‘{print $8;}’ | sort | uniq -c | sort -rn
181 (Worm.Gibe.F),
86 (Worm.SCO.A),
2 (Worm.Dumaru.Y),
1 (Worm.Sobig.F),

看到Julian Elisher的一段话：

Note: these were very early.. things have changed a lot since then. IGNORE THESE They are for my ammusement only and will misslead you!

然后我明白了：

牛人和普通人的区别就是，当他们说胡话的时候，你根本看不出来他们到底是不是在说胡话。。。

This is useful when you want to connect remote “Local” network through a PPTP vpn. First, install the ports/net/pptpclient, by doing:

cd /usr/ports/net/pptpclient
make all install clean && rehash

Lyric:

love in your eyes
sitting silent by my side
going on holding hand
walking through the nights

The hardware of beastie.frontfree.net (this machine) seemed to be endsuring some problem. Today, I have completed several improvements to mitigate this situation.
