近日在报上看到了韩乔生老师的一则早期作品,不知道是否真实,摘录如下

一个骑兵在作战中不幸被俘。

“我们会杀掉所以俘虏,”敌军首领对他说:“不过由于你在作战中表现英勇,令人佩服,我可以三天后再杀,在此之前满足你三个要求。现在,你可以提第一个要求了。”

骑兵想也没想,说:“我想对我的马说句话。”首领答应了,于是骑兵走过去,对他的马耳语了一句。那马听了后,长啸一声,疾驰而去。黄昏时分,马回来了,背上驮着一个漂亮女郎。当天晚上,骑兵便与女郎共度良宵。

JFYI, it was released at the usual location, with BSDTAR installed by default. I tend to remove COMPAT4X and COMPAT3X in the next release.

CFLAGS='-O2 -pipe' WITH_BSDTAR=yes COMPAT4X=yes COMPAT3X=yes BOOTWAIT=0 ENABLE_SUID_K5SU=yes

I haven't received any mail for a long while. What is happening?

DragonFlyBSD 1.0-RC

| No Comments | No TrackBacks

Matt Dillon has released the RC today. You can download the RC here:

http://www.dragonflybsd.org/main/download.cgi
ftp://ftp.dragonflybsd.org/iso-images/dfly-1.0RC1.iso.gz

Matt said that he will also announce this on FreeBSD list.

Apparantly there is some sort of DDoS attack against www.FreeBSDChina.org. What was that? Some internal information told me that it was an intended test against www.freebsdchina.org. We have found some defects in the original website design and that should be corrected soon.

I have plugged a workaround to defeat the DDoS attack, now the load average fall from 70 to 0.65.

I'm now 22 years old. It's Monday, just like 22 years ago when I was born. First of all, I shall thank my mother for giving me life and my parents who grow me up. Thanks to all my friends who gave me pleasure and shared my sorrow. Well, I have to thank those who taught me what real life is, too.

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 :-)

标 题: 大学论文:从激光原理看六脉神剑的产生机制zz

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。

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

| No Comments | No TrackBacks

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。

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?

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.

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:

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.

I have added some SYNFLOOD proof packet filter rules for beastie.frontfree.net. Interestingly, the filter options seems to "forge" beastie.frontfree.net to be an OpenBSD box.

marcel has finally imported gdb into FreeBSD-base. Now we can debug kernels again.

niklas has committed the final SMP branch code, no more SMP branchs, we have SMP in OpenBSD-CURRENT now!!

I have posted it as rev. 1.5 of research.delphij.net/freebsd/rfc3522.diff. Some minor comestic changes has gone into the patchset, as junsu pointed out. I'll remove the unrelated ones soon.

哭笑不得

我就知道这事儿会招来很多无聊的人,电邮,电话,再到MSN——前天转的几篇文章居然能引起这么强烈的反应,而且居然能够被总结成“处女”,“色情”,真让人哭笑不得,让人觉得这儿突然变了CxDN……我觉得这几篇文章都是相当严肃的主题,而且,这几篇文章在讨论什么,通过转这几篇文章想表达什么,我相信清者自清,没必要解释,我也不想去谴责谁,这只是不同的人生理念而已。

我只想说我不后悔当初的选择,虽然我,至少是当时,并不喜欢那个选择的结果,但至少那是作为一个愿意为自己行为负责的人当时唯一的选择。

妹妹的问题如下:(呵呵!好不容易才搜到这个帖子)

我GG要和我做那个,我很犹豫,他说现在做过的太多了。我相信他的话,但作为女生这方面就得想多点,“以后要是他不爱我怎么办?”,“如果再找别的男生,会不会因为这个而有什么想法?”但我很爱他,不想让他失望,我该怎么办呢?

一、你相信谁?
  有一年登山社去登山,其中有一对感情很好的情侣在一起.
  当他们到山下准备攻峰时,天气突然转坏了,但是他们还是要执意的上山去.
  于是就留下那个女的看营地,可过了三天都没有看见他们回来.
  那个女的有点担心了,心想可能是因为天气的原因吧.
  等呀等呀,到了第七天,终于大家回来了,可是唯独她的男友没有回来.
  大家告诉她,在攻峰的第一天,她的男友就不幸死了!
  他们赶在头七回来,心想他可能会回来找她的.
  于是大家围成一个圈,把她放在中间,到了快十二点时,突然她的男友出现了还混身是血的一把抓住她就往外跑.他女朋友吓得哇哇大叫,极力挣扎,这时她男友告诉她....
  在攻峰的第一天就发生了山难!
  全部的人都死了只有他还活着........
  你相信谁?

I have said the statement when I was 14. Yesterday, a friend of mine told that he has quoted it in his dissertation addendum. I am sure that there are a lot of misunderstanding of the above statement.

Top ten established HTTP connection from IP to our box: (IP=127.0.0.1)

Merge FreeBSD-CURRENT changes to delphijfork:
retag `cvs -d /home/fcvs rdiff -rHEAD -rDELPHIJ_FORK_LASTMERGE src | grep Index: | awk '{print $2;}' | grep src`

David O'Brien has just imported binutils 2.15 snapshot into FreeBSD src repository. What's more, he stated that he will do gdb 6.x import soon. This will drastically improve the debug and development environment in FreeBSD.

I have uploaded delphijfork 20040615 snapshot isos, which is based on FreeBSD 5-CURRENT.

MD5 (5.2-delphij-20040615-i386-bootonly.iso) = 98c8429770d70dc5e10760cac6154f54

cvs updated again

I think FreeBSD will soon release a new advisory. Simply put, cvs updated again and is vulnerable to some potential security risks.

蠢事1,2,3

| No Comments | No TrackBacks

当一个月前突然知道自己做了一件那么愚蠢的事的时候,我觉得有点讽刺,我没想过自己竟然在无意中作了那样一件事,真好笑,我一直觉得自己是那种总能够先为别人着想的人。后来这件事我跟身边的几个人聊起过,他们的反应都非常冷漠。

我意识到问题的严重性,其实这就是惩罚,5年……唉,然后觉得张飞的流水帐里面那句话非常的富有哲理:“突然间我明白了两件事情,鸡蛋永远也不知道狗的乐趣;袜子破没破只有自己的脚知道。”

I will be answering questions about my disseration on 16th, June. I will work hard for the answering, including PowerPoint Presentation, the design and implementation internals of the GridDistribute system, etc.

Big news. FreeBSD is calling for more developers to take attention on 5.3-RELEASE development, the 5.3-RELEASE, a.k.a. first 5-STABLE release, will begin its release engineering process in 4-6 weeks.

If you are using FreeBSD and willing to migrate to a 5.x branch release or 5-STABLE, it is highly recommended to use -CURRENT and report any problem you encounter. Also, you can help the development by checking out something on TODO list, or resolve some problem.

走出混沌……

正在寻找一切混沌的出口,不知道能不能找到,不知道找到了,是否只是从一种混沌跃迁到另一种混沌,然而我知道自己必须走出混沌……

昨天忙了整整一天,错过了小学同学的聚会。

最近的事情太多了,多到应付不过来,多到让我觉得overloaded,身心俱疲,论文,工作,学业,国际会议,等等。端木那天转述他的老板的话我觉得很有道理:先去做那些重要的事情,而不是那些紧急的事情——我想起了自己毕业设计里面的调度系统,实现的实际上也就是这样一些简单的规则,节点很多,而调度评估某个任务不重要或重要的指标,就是请求数和确认数的加权和。

I have noticed that today's cvsup brings this to my local repo: src/sys/kern/kern_kse.c. From the version it seems to be from kern_thread.c. Waiting commitmail to explain this.

Apache2 RCng'ified

FreeBSD Apache2 port has been RCng'ifyed since 2.0.49_2. This will unify the behavior of ports more.

From FreeBSDChina's forum:

熬夜伤身,按时作息才能保持身体硬朗,否则,铁打的身体,也受不了日夜劳顿,因此,想要熬夜的您,千万记住:

1:不要吃泡面来填饱肚子,以免火气太大,最好尽量以水果、土司、面包、清粥小菜来充饥。

2:开始熬夜前,来一颗维他命b群营养丸,维他命b能够解除疲劳,增强人体免疫力。

3:提神饮料,最好以绿茶为主,可以提神,又可以消除体内多余的自由基,让您神清气爽;但是肠不好的人,最好改喝枸杞子泡热水的茶,可以解压,还可以明目呢!

4:熬夜前千万记得卸妆,或是先把脸洗干净,以免厚厚的粉层或油渍,在熬夜的煎熬下长满脸痘痘。

5:熬夜之后,第二天中午时千万记得打个小盹。

It appears that NetBSD has finally adopted packet filter, an OpenBSD feature to its base. Compared to FreeBSD's pf port, this will be much easier one because the VM structure is almostly alike.

Let's review what I have did years ago. I say, nothing can claim itself secure! Nothing, nothing, nothing!!

It seems that Bruce A. Mah is willing to take a break...

  此前,我和中国学生的多次交流都是围绕如何达到优秀和卓越,如何成为领导人才而展开的。最近,在新浪网的聊天室和我收到的许多电子邮件中,我发现更多的中国学生需要知道的不是如何从优秀到卓越,而是如何从迷茫到积极、从失败到成功、从自卑到自信、从惆怅到快乐、从恐惧到乐观。

mono FreeBSD port?

I am not sure whether there's someone who wants to pick up mono's FreeBSD port. I personally do not want to do this :-) However it will be interesting if I have enough time to kill. And, of course, it will be good if it is released under a more loose license...

本着“如果没有就写,如果有不合用就改,有合用的能用打死也不写”的精神,终于决定给 www.delphij.net 加个留言板……因为是双语的,而且www.delphij.net是英文,因此这里也写段英文来照顾老外的情绪:

我不知道自己是不是一个坚强的人,因为并不是每件事我都能够坚持不懈地做到底,我也会放弃,我也会做错,我只是在许多时候坚持了自己的信念,我只是在别人放弃的时候能够坚持下去,尽管这么做不一定对。
