FreeBSD

Today the 6-STABLE branch has been named “6.0-BETA5”. A lot of known issues has been addressed and fixed. This beta has disabled the debugging options found in -CURRENT as well.

Recent commits apparantly fixed the livelock issue. This saves my own server (this one) finally. Thanks Suleiman and Alexendar! You heros!!

摘录一些。bsddiy是国内非常著名的BSD Hacker，你可能听说过他的另外一个名字(此处不便透露)。

有很多人问我「BSD是独立的一蹴，我们有自己的圈子，我们不以商业驱动，追求完美是我们的源动力，任何不好的代码都不能在这里存活」这一句的出处——当然是bsddiy老大，他的原话是：

Andre Oppermann (andre@)开始行动了！希望我们在3个月后能够看到焕然一新的FreeBSD TCP/IP实现！

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)

The service there is expected to be down for a while. I think I can get everything back tomorrow.

gjournal is one of the Google Summer of Code projects that is FreeBSD related. It provides data journalling service that will be useful for frequent randomized area writing, just like write clustering.

Today, the first public alpha version has been released.

Please note that this is not intentional to replace SoftUpdates nor a real journalling file system, as the metadata consistency protection is different than just do data writing journalling. However, this indicates a good way of providing better performance for file systems.

After RELENG_6 has forked off, we now have 1MB+ diff’s against HEAD.

Merge some of them?

Colin has finally added portsnap and related stuff (bsdiff, etc) to FreeBSD 7.0-CURRENT. This would not be MFC’ed before 6.0-RELEASE, but still good enough because it will attract more users to use it.

Portsnap is a secure and efficient alternative to the current ports tree update approach. Since it goes through HTTP, it is much easier than other existing methods to use it to obtain ports, especially from some brain-damaged administrated networks.

本周应该差不多了吧，不知道会有多少个RC哦……
