FreeBSD 6.0-RC2

(最后修改: Development

I think we would be going to release 6.0-RC2 soon, to encourage more testing against the recently caught issues that addressed several race conditions, etc.

Signal in init(8)?!

(最后修改: Development

Strange thing happen.

  1. Start your FreeBSD single-user.
  2. Run /etc/netstart so your network is up.
  3. Run /etc/rc.d/sshd start so you have sshd
  4. Use ssh to login localhost, then su(1) to root
  5. Type “init q”

Then init(8) would crash with signal 11. Yes, it was killed. As soon as kernel found this, it would panic with “Going nowhere without my init!”.

Preparing for 6.0-RC1

(最后修改: Development

Well, this Saturday and Sunday is not for rest, because we have a 7-days’ vacation from October 1.

I think FreeBSD 6.0-STABLE (RELENG_6) is in a quite nice shape and it’s a good time to cut 6.0-RC1 (also RELENG_6_0) and be more careful committing code against RELENG_6. However, according to my diff service there are still a lot of unmerged changes.

I have submitted a plenty (about 4 or 5 or even 6 dozens) of MFC requests last week. I wish that the diff reduction part of these changes, in conjunction with important bugfixes, would got approved soon so we will have a healthy RC1 for test.

www.delphij.net 改用 lighttpd

(最后修改: Development

易帜了!易帜了!

经过测试发现,lighttpd的性能要比Apache好。虽然还不是很熟悉,但是这一步迟早要迈出去的。我觉得一个技术人员的生命终结的标志就是开始毫无理由地拒绝尝试新事物。

How to make FreeBSD to permit several programs to play sound simutiously?

(最后修改: Development

You may have noticed that FreeBSD by default does not allow many programs to play sound at same time. For instance, you generally can not hear GAIM sound when you are hearing MP3.

Fortunately, this can be resolved if you have read the documentations. Now I write here so you can also Google it :-)

Add a single line into /etc/sysctl.conf:

hw.snd.pcm0.vchans=16

Then, reboot (or if you are careful enough, shut down all programs that is using sound subsystem, then run /etc/rc.d/sysctl restart)
