Preparing for an interview with David Xu
Today folks at FreeBSDChina suggested me to have an interview with FreeBSD’s David XU (Yifeng XU), who is an active committer, and possibly the only src committer living in the mainland China.

Well, this is fun. There are over 460 files in the 5.x source tree (360 in DFly) that make calls to malloc(… M_NOWAIT), and so far about 80% of the calls that I’ve reviewed generate inappropriate side effects when/if a failure occurs. CAM is the biggest violator… it even has a few panic() conditionals if a malloc(… M_NOWAIT) fails. Not Fun!

Q: Is managed thread just a thin wrapper over Win32(native) thread?

I have announced a suspension and delay of the revision of my x86asm tutorial, as in cvs of the doc/x86asm/index.html, rev 1.2, on December 27, 2003. Today, I have made a back out of that.
Special thanks to: junsu and smalltong02 for helping me on getting out from the influence of the December Incident.

日记节选.
以前听说微软在界面开发上投入了大笔的经费，其中的一些故事(如他们请人去用新的产品，把全过程拍下来，然后一点一点研究)也许有些夸张，但今天算被cygwin的安装程序狠狠地折腾了……

阅读全文…First commit caused by automated checker
Today ru has committed the first patch from the Stanford Metacompilation research group. Kip Macy has pointed the website of them to me.
The submission is awesome that they are mainly leak-related, which is hard to trace and will trigger strange problems where we will spend hours and even days to track down. The original post was submitted to FreeBSD-Hackers maillist here.

junsu has pointed out a problem that when we click on “More…” the link will bring us to a monthly archive and not the blob we want. I have noticed the same thing and did not took my care in the past.
This is apparently a misconfiguration. In weblog configuration (Should have administration privilege to see that), you are allowed to choose “Preferred archive style”, which was mistakenly setted to “Monthly”. By setting it back to “Individual”, the problem goes away.
参与评论alc commit了一个workaround但我还觉得不对头……
sys/vm/uma_int.h, rev 1.23是一个对于junsu几天前发现的问题的workaround。Alan说「Thanks. I’ve committed a change making a slightly larger increase to UMA_BOOT_PAGES.」
