I lost the bookmarks on one of my machines that I use to look for obscure content being hosted over p2p. One of these sites was similar to the internet archive's discmaster, where it kept a frequently updated database of the file metadata of torrents being shared by public trackers and allowed you to search by filename. For example, you could search ".c" and get a list of torrents with source code files. The site also had a feature that would let you browse its most recently collected metadata.

I'm also open to any alternative sites or self hosting an oss solution.
