FreeBSD

The current FreeBSD Soft Updates poses to a performance peanlity when there’re plenty of i-nodes and this is very common case in badly-designed systems, however, I think this should be solved.

The migration apparantly gots its result, 30 times of increase here. No old hardware any more!!

I don’t want to do this, but I can not bear beastie.frontfree.net any more. It continously generates troubles for me, and in addition, the configuration is too poor for me, not only compared to the other servers I moderate, but also to the modern computers.

I hate them, really, really hate them, they are abusing the machine and I have to spend much time on dealing with the mess they generated.

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).

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”.

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
