www.delphij.net 改用 lighttpd

2005-08-22 22:10 | 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?

2005-08-16 21:02 | 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)

口水仗又打起来了……

不到4分钟就有人反对我提高某一默认值的提议，不过我还是在游说这样做的好处。

Colin Percival has imported his bsdiff related stuff

This is an important step of getting the tools like freebsd-update and portsnap into base system, which provides good method of updating the base system (through binary updates) and ports tree.

AMD64 string function optimizations

2005-08-03 09:14 | Development

So time comes that we should consider whether some of our string operations is not optimial and needs some operation. NetBSD seems to have done a lot of good work to make their MD layer better, and we should take these improvements if they are proven.

David O’Brien has pointed out that we should be careful on this, however, since some micro optimizations may hinder performance in a large scenario. With this concern in mind, I will redo some more benchmarks and request for -arch@’s idea before considering commiting the patchset. Currently, the NetBSD implementation of swab(2) is proven to be slower than the GCC generated code by about 25%. I will look into the assembly code generated to see whether I can help to solve this.
