选择chaos这个词是因为~~实在很难找到一个更合适的词来形容这儿了……
昨天哥们打电话说要去学校办成绩单,准备跑路了。

能说得到一起的人又少了一个,想起了大一时候在楼道里,一大票兄弟一起看书,琢磨高数的情景。
Read more...最近 current 邮件列表讨论的很凶的一个问题是,MySQL很不理性地在每一个I/O操作时都调一次time()。这一操作在FreeBSD上面相当的昂贵(为了保证精度),而Linux采取了许多优化(有些是牺牲精度的)措施,因而性能差距越来越大。
于是有一个人在FreeBSD上做了试验,说改一下默认的时钟能够将性能提高6倍……不带这么玩的,ft……
BTW. clive也测了一下,在他机器上结果是:

你注意过你的父母吗?
如果有一天,你发现***厨房不再像以前那么干净
如果有一天,你发现家中的碗筷好像没洗干净
如果有一天,你发现母亲的锅子不再雪亮
如果有一天,你发现父亲的花草树木已渐荒废
如果有一天,你发现家中的地板衣柜经常沾满灰尘
如果有一天,你发现母亲煮的菜太咸太难吃
如果有一天,你发现父母经常忘记关瓦斯
A collegue of mine has reported a FreeBSD “bug” that, when the main thread exits, the whole process is terminated. He complained that pthread_detach() would not cause the thread to run without the main thread, while Linux did.
With some experiments we have figured out that this is actually a Linux bug, which violates POSIX. Interestingly, Solaris has the same behavior that FreeBSD have.
The POSIX pthread_create() said:
_"Note that the thread in which main() was originally invokeddiffers from this. When it returns from main(), the effectshall be as if there was an implicit call to exit() usingthe return value of main() as the exit status."_
And, the exit() said:

Read more...It seems that we still have some race conditions that can lead to strange issues and we may want to discourage this for 6.0-RELEASE.
Alan Cox has committed some fixes for the issue, hope these can be merged back.

从十一开始已经快一个月了……问题仿佛越来越多,不过,我相信我们能战胜问题。
Read more...我不是做销售的,我要做的是告诉人们真相,而不是顾及谁,或者某社区的面子。
有人指责我做这种侵略性的宣传不好,但是我还是要做——难道允许你们整天整天把大便说成是金子,就不允许我告诉人们它真的是大便不成?别忘了,我只是还原事情的本来面目。
至于那些连CS101都没有打通的2B销售人员,那些迷信的狂热分子,我跟你们没有共同语言,如果你们敢于在我的社区放屁,我一定要把你们的无耻谎言批得体无完肤!
