Gmane – Mail To News And Back Again

Gmane – is an interesting project that provides archiving and comfortable interface to a huge number of mailing lists. What they do is subscribe to a huge number of mailing lists, receive and index messages. They also provide archives over web and NNTP (news). And they even allow to post without subscribing to mailing lists (they do use one-time confirmation though).

Sounds good? Add to that that the service is totally free, and it willsound even better than good.

Building a Vector Space Search Engine in Perl

There is a very interesting article at Perl.com. It is about building a search engine using perl language. The interesting part is that the article is not about the usual reverse index type search engines. It takes a different approach – vector space searching.

Reading the article reminded me of the few things:

  • The subject of searching is interesting to me.
  • Perl is great!
  • Linear algebra is actually useful and I should take it again (and pass it this time).

List of User-Agents

If for some reason you need a list of all sorts of different web user agents (spiders, robots, crawlers, browsers), then you can check the list here. These are separated into three huge pages with descriptions, and links to the vendors’ sites.

This might be useful when writing a robots.txt file or developing a site with different content varied by the web client.

Bash prompts

Maintainer of the Bash Prompt HOWTO, it turns out, also keeps a small website with examlpes of different bash prompts. It provides screenshots together with code for some really wicked prompts. If you are into that kind of things, but all of ideas, than check the site out. Maybe you’ll find something for yourself. :)
