CryptSharp provides a number of password crypt algorithms: BCrypt, MD5 (and Apache's htpasswd variant), PHPass (WordPress, phpBB, Drupal), SHA256, SHA512, and Traditional and Extended DES. It also includes Blowfish, SCrypt, and PBKDF2 for any HMAC (.NET's built-in PBKDF2 implementation supports only SHA-1). If you are looking to store passwords, odds are CryptSharp will have the algorithm you want.
NetIRC2 is an easy-to-use .NET IRC client library. It supports all major features relevant to making a chat client or bot. It has full support for synchronization contexts. You can use it from a Windows Forms or WPF GUI thread and chat events will be automatically dispatched, allowing you to completely ignore multithreading. It uses byte arrays internally, so mixed encodings can be handled. The IrcClient class can even be used as a component in the Forms Designer. Because it speeds up connect times with some IRC servers, an Ident server is included as well.
SyncServer is a Firefox sync server written in Perl. Mozilla's Firefox sync server, which is written in Python, has many dependencies and is quite tricky to install on enterprise distributions which don't ship with all those requirements. This syncserver implements the syncserver user API and storage API as an fcgi application. It is entirely written in Perl.
phpilelist is a file listing script that you can upload to a directory on your Web server. There's just one file to upload, and the script will list all files with extensions you specify and make them available for download. If you add, remove, or rename files, the listing will automatically update. If the directory contains a file named 'readme.txt', the script will show this file's contents above the download links.
