Two remarkable pieces of writing in the blogosphere today, both ending up in the instant classics section of their respective categories.
The first one is a tutorial style piece exposing the inner life of a search engine. A simple full-text search engine in 200 lines of Ruby. It's concise, it's clear and after reading it anyone can write a simple search engine. If only all things in the world of code were explained that well.
The second one has been linked from all over the place, including some A-listers, so this probably doesn't come as news. But it's so good it deserves all the attention it can get. Socrates takes on WS-Mumbojumbo: The S stands for Simple.
