simon willison on redis

Proving again and old-school c is still fast and relevant, he talks about a "data structure" storage server (that which is not a database, but still a means to store data). Any programmer can see why this would be a valuable hook for the debugging process (think HSQL, MockDB, etc).

The fascinating tidbit at the end of the article is what got me interested however:
hurl.it

"Hurl makes HTTP requests. Enter a URL, set some headers, view the response, then share it with others. Perfect for demoing and debugging APIs. "

Sounds like a great addition to a system test toolkit for anyone who works on web apps.
