gwan web application server
http://gwan.com/
G-WAN runs C, C# or Java with less CPU and less RAM while handling more requests than other servers. Other languages (Go, PHP, Python, Ruby, JS...) benefit from G-WAN's multicore architecture.

Mongoose webserver - single file embedable webserver coded in C
From the website http://code.google.com/p/mongoose/
Mongoose is an easy to use web server. It can be embedded into existing application to provide a web interface to it.
Mongoose web server executable is self-sufficient, it does not depend on anything to start serving requests. If it is copied to any directory and executed, it starts to serve that directory on port 8080 (so to access files, go to http://localhost:8080). If some additional config is required - for example, different listening port or IP-based access control, then a mongoose.conf file with respective options (see example) can be created in the same directory where executable lives. This makes Mongoose perfect for all sorts of demos, quick tests, file sharing, and Web programming.

Or, Let Picard ID Your Music
If you'd prefer a bit more control over your music id'ing than the previously posted ruby script, then Picard should fit the bill. I'm using it in conjunction with the noted script.
http://musicbrainz.org/doc/PicardTagger
From the site:
Picard is the next generation MusicBrainz tagging application. This new tagging concept is album oriented, as opposed to track/file oriented like the ClassicTagger was. Picard is written in Python, which is a cross-platform language, and makes use of cross-platform libraries - this allows the same code to run both on Windows, Linux and Mac OS X.

Let Ruby ID Your Music
Tender Lovemaking » Blog Archive » Identifying unknown music with Ruby
A quick intro noted above from the author of the earworm gem. A really cool piece of work for identifying music files.
Here's how I am using it -- note that I'm also using rbrainz, another really neat piece of code.. This code needs to be a bit neater/more functional, but it was a quick solution to a bunch of mp3's pulled down from spinner.com's and daytrotter.com's mp3 of the day pages.
What it does:
Walks a file hierarchy finding *.mp3/*.MP3 files.
Renames the file based on the id3 tags in the file.
Relocates the file into my Music directory in the proper file hierarchy based on the id3 tags.
If it can't id the file via id3 tags, it tries to id the file via rbrainz, and update the tags
If it can, it relocates the file appropriately
If it can't it dumps the file into Music/undertermined -- I can come back next month and try the id again.

Evolution + clamav + ruby
Quite a while ago I tied Evolution to clamav via ruby as an anti-virus measure ( I don't recall, but I most likely based this off of something similar, but not using ruby, that I found via Google ). I recently passed this setup on via the Evolution mailing list in reference to a posted request for examples. After a bit of back and forth, it appears to be working for the requestor. At his suggestion, I'm posting the configuration here also. The filter configuration is shown in the image, and the actual script is listed after. You'll want to make whatever minor adjustments necessary for it to work in your environment and you'll probably want to comment out the segments associated with creating the logfiles -- they will end up eating a lot of disk space( comment out the lines referencing fp and Time).
Click the image to see it clearly.
The script file -- rubyclamav.rb

Anyone who wishes can read these titles online — no conditions, no strings attached. (Later we may ask for an extremely simple, name & email only, registration. ) Or, if you prefer, you can download the books in one of several formats. Again, with no conditions or strings attached.
