Why I am not fond of DHCP in lab environments
Using DHCP to assign IP addresses is pretty popular in environments withlots of machines. You'd think that student labs, full of generic machines,would thus be a great environment for DHCP, but actually I disagree; Ibelieve that (normal) DHCP is not a great match for a lab environment.
The problem with DHCP is that it ties the IP address to the wrongthing. In a lab environment you don't want a machine's IP addressto be tied to its hardware; you want

嘉賓： 網絡暴民
網絡暴民很斯文，許多話在節目完結之後才說出來，我不停頓足「你剛剛怎麼不說？」做網摘的人當是無底深潭。搞IT的都是斯文人，讀文學的倒冒進急躁動手動腳。沒有在咪裡

遇上志同道合的同事，當然是檢查可有帶合適的衣服，孖公仔clubbing去。

How to have your web spider irritate me intensely (part 2)
In the spirit of previous cleverness ,here's a simple new technique:
Have your web spider make up random Referer headers.
This wasn't Referer spamming, since the websites in the Referer headerswere completely random URLs, apparently drawn from legitimate sitesaround the Internet (often repeated). Nor were the websites ones thatactually linked to us, or had any relationship to the URLs that werebeing crawled.
Even in low volume this is a sure-fire ticket to our kernel level IPfilters, since it
A gotcha with <textarea>
Textareas are one of those treacherous areas of web programming, becauseit is really easy to get them 95% right and then never notice thatyou've fumbled the remaining 5%. The problem area is textareas withinitial content, for example blog comment previews ;what almost completely works is to just put the raw content into thetextarea in your HTML. This approach makes intuitive sense and evenworks fine if you test by throwing markup in, like '

Why DWiki doesn't use fully REST-ful URLs
REST is a style of web application writing where, among other things, youuse simple structured URLs to represent resources instead of heavilyparameterized ones. For example, 'https://example.com/users/cks/' is aRESTful URL but 'https://example.com/users?name=cks' is not.
(RESTful URLs are virtuous for a number of reasons, including being lessalarming to search engines and being simpler, so it's easier for peopleto remember them
