给McKusick老伯发了一个46KB的patch...

主要是空格的问题。我打算接下来的一段时间琢磨琢磨SoftUpdates，如果这个patch能commit的话，delphijfork的diff一下就能减少46K :-)

摘要：
六脉神剑具有广阔的应用前景，本文从激光原理出发，论证了生物激光的可行性及实现的办法，在人类进化事业中，具有十分重大的意义。 背景： 与传统的武功，如降龙十八掌，九阳真经等相比，六脉神剑是一种威力极强的武功，具有 操作简单，响应时间快，杀伤力大（功率密度大），效率高，使用范围远等优点，因此为 广大的武学名家所觊觎，但是由于大理段氏将这门武功列为绝密档案，而且存在修炼困难 等问题，六脉神剑的产生原理，始终是武林中的一个谜，作者从事激光器理论研究多年， 终于凭借两条基本假设，解决了生物激光产生中的若干困难问题。并提出了一种快速修炼六脉神剑的方法，本文的发表，具有划时代的意义。

FreeBSD 5.2-delphij to release third iso

I will release third (more or less unstable) release ISO if nothing will prevent me from doing that :-) The latest delphijfork includes several new features, which is tend to exhibit new technologies and possiblities of FreeBSD:

• An implementation of RFC 3522 ported from DragonFlyBSD
• An implementation of Early Retransmission ported from DragonFlyBSD

Also, FreeBSD-CURRENT has several new features, including:

• In progress import of binutils 2.15
• pf 3.5. Including several new features and works better with spamd.
• better ACPI support

一位台湾校长的讲话

From ChinaUnix.

台湾有这么一所学校，学生年龄在15－18之间，每年三千多学生中，因违反校规校纪被校方开除的二、三百人。学校没有工人，没有保卫，没有大师傅，一切必要工种都由学生自己去做。学校实行学长制，三年级学生带一年级学生。全校集合只需3分钟。学生见到老师七米外要敬礼。学生没有寒署假作业，没有一个考不上大学的。这就是台湾享誉30年以道德教育为本的忠信高级工商学校。在台湾各大报纸招聘广告上，经常出现"只招忠信毕业生」字样。

Shall we patch a (possibly) non-exploitable heap overflow?

While I believe that proactive security practice is necessary for every consumers, the most conversave ones should argue that even a security update will possibly break compablity.

Now I am in trouble. With rsync 2.5.5 installed on a FreeBSD system, we know that it is possible to overflow its heap, however, shall we patch it, or just let it as-is because it is not exploitable on FreeBSD, unlike Linux’s silly brk(9) implementation?

NetBSD have pf(4) in its src repository now!

Finally, yes, itojun has imported pf(4) into NetBSD. Having pf(4) in base indicates that NetBSD’s recognition of pf(4) related work, and as security officer of NetBSD, itojun-san’s import have some special meanings.

beastie.frontfree.net under SYNFLOOD attack!

I have watched spurious SYN messages and apparantly this has affected beastie.frontfree.net’s networking subsystem, namely, its mail system. The attack is from 203.81.27.11.

Whois indicates 203.81.27.11 is:

Command line I am using to analyze script execution time on Apache log

grep cgi-bin scripttime | cut -f6,8 -d’ ’ | sed -E s/\\\?.+//g | grep cgi-bin | sort | uniq -c | sort > statis

Where scripttime is a log with %T (script execution time) log. The above command line will obtain execution time, script name from log, then sort it by the execution time, then have a counted unique.
