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

Why I think that DNS whitelists are going to fail

There's been a recent fad for DNS whitelists, the rough inverse of DNSblacklists; instead of listing claimed bad sources of email, they listclaimed good sources. I've been thinking about this for a while, and Ibelieve that such DNS whitelists are going to fail.

Why I believe DNS whitelists are doomed can be summed up in a simplequestion: do you whitelist Hotmail or not? If you whitelist Hotmail, youare whitelisting a known source of a not insignificant amount of spam.If you

First impressions of pyOpenSSL

pyOpenSSL is a high-level Pythonwrapper around a subset of the OpenSSL library (to quote it). It waspulled onto my machines recently as part of a Fedora update, and sinceI'm currently interested in OpenSSL-related things I decided to playaround with it to try it out.

After writing some basic stuff, I have to say that I like it. It's notentirely documented (and for some things you really want to read theOpenSSL manpages too), but it works fine
