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:
Archive of all Edsger W. Dijkstra works can be found here. For those of you who don’t know who he was, here is a quote from the site:
Edsger Wybe Dijkstra was one of the most influential members of computing science’s founding generation. Among the domains in which his scientific contributions are fundamental are
- algorithm design
- programming languages
- program design
- operating systems
- distributed processing
- formal specification and verification
- design of mathematical arguments
In addition, Dijkstra was intensely interested in teaching, and in the relationships between academic computing science and the software industry.
During his forty-plus years as a computing scientist, which included positions in both academia and industry, Dijkstra’s contributions brought him many prizes and awards, including computing science’s highest honor, the ACM Turing Award.
Most of his papers make for a rather entertaining read. (For example, the thingy about hungry professors and semaphores).
