Security

感觉现在反垃圾技术发展到了一个坎上，短期内恐怕不会什么大的技术突破。基本的技术就是黑白名单、内容分析、特征分析。垃圾邮件发送的技术最近也没什么大的进展，目前我能够做到的漏判大约是万分之七，误判万分之五左右，前一阵考虑的技术还没有时间去做……

It seems that the official FreeBSD qmail port’s disable-qmail (as well as the Live with Qmail documentation) will need write access to /usr/bin and /usr/libexec, and hence the “fast jail” script I have written has been rendered useless :-(

I will investigate the issue this weekend and hopefully I will be able to work around the issue.

Today liukang has suggested some software that will fight against blog spamming. They are:

http://www.jayallen.org/projects/mt-blacklist/

and

http://www.neuro-tech.net/archives/000315.html

The first is MT plugin and the second is its data automatic updater.

I’ve no time to turn them into ports at this time. Will try them on my box and if I have time I will port them.

It seems that my blog get spammed by various parties. I hereby declare a war against spamming, also for e-mails.

You’re being watched and identified from this point on. Once you spam my blog, I guarantee that your activations are being tracked and analyzed with my knowledge base system and finally I will be able to keep everything from you off my site.

RFC也许有时让人觉得过分冗长，但是如果你没有耐心去完全实现它，它就会在不经意间突然咬你一口。

可怜的端木就被咬了……

今天这家伙发了一封邮件给我。

嗯？3.5分？

Windows XP SP2 is an important update and have introduced many security improvements. However, after installing Windows XP SP2, some graphical identity systems will be rendered to be useless.

The root cause is that these systems makes use of a special MIME type: x-xbitmap, or so called “XBM”.

XBM is originally developed by the X community. Presently it is uncommon on the web. However, banks like China Merchant Bank utilizies this format for authentication.

Finally done my task! So glad to announce this ;-)

It seems that I still need 25 spams before I can get beastie.frontfree.net’s Bayesian system to be functional again. This really took me long time because nowadays PhantasmMail has much better spam dealing policies.

It seems that Microsoft is still testing/finalizing the Windows XP SP2 release. Up to today’s check, it is not released here. Interestingly, a Korean edition (Korean is another asian language, which is usually listed with Chinese) has been released much more earlier, even before Japanese and Chinese (both Simplified Chinese and Traditional Chinese) editions.
