Enterprise File Exchange (EFX) slots in where email file attachment size limits stop your users from sending files to another person. In the EFX system, the user visits the EFX site, uploads the file, enters the receiver's email address, and lets the system notify the receiver that there's a file waiting for them via a simple email message. The receiver then either simply clicks on the download link provided in the email message or visits the site to download it from there.
deco is a command-line program that, together with the deco-archive package, allows you to extract dozens of popular archive file formats. It has a consistent interface ("deco 1.tar.bz2 2.rar 3.zip 4.flac 5.deb") and consistent behavior (never deleting archives after extraction and extracting relative to the current working directory, just verbosely enough, all unless explicitly requested otherwise). It creates an extraction directory if there is more than one file or directory at the archive top level, and it is able to fix strange permissions.
MySqueaks is a PHP class that allows you to create MySQL statements with the flexibility of OOP and throws in a simple database interface as well. This means that you can create PHP objects to represent your database tables and use the various methods provided to select, update, or delete data. This also means that instead of having to write out a very long SQL query, you can simply convert the representation into a series of "steps", which can be easier to understand and debug.
