BackPlay a program that plays music files from a folder in the background.

It can be paused from an icon in the status area.
backstep.py is a backup program that can be run in a directory. It makes a snapshot backup of the directory in a specified interval. The system backs up every file that has changed or was created in the specified interval. The user can restore a backup by telling the system to restore a backup that is a given amount of time old.
BackupMX consists of two programs, 'Store' and 'Forward'. Store accepts SMTP connections, takes all mail given to it, and stores it in a file. Forward takes that file and forwards it over SMTP to a fixed destination. This is code for integrating into your own projects rather than using as is. It is suitable for creating a disaster-recovery mail handler, but would also make a good basis for a spam filter, a tarpit, a honeypot, or a greylist filter. It is written in simple C, and has no external dependencies such as libsmtp.
Bad Peggy searches for damaged JPEG files and validates and verifies pictures for truncation and other blemishes, which sometimes occur when such files are downloaded or restored from bad backups. It's fast, easy to use, and reliable in the analysis it does. It uses all available CPU cores too.
