webtools.class is a PHP class of useful functions for websites, including connecting to MySQL (with error reporting), IP-to-location information, creating salted MD5 passwords and validating MD5 passwords, shortening URLs with the Bitly API, email validation, and sanitizing user input.
GenScriber is an editor for the transcription of census records, church records, births, marriages, baptisms, burial registers, etc. It is intuitive and easy to use. The interface is comprised of several resizable windows within a single main window. A register image can be viewed in the top window while data is input in the bottom window.
Hados stores files in a cluster of servers. Its goal is to handle high availability by storing copies of the same file on several nodes. It provides RESTFUL APIs to easily store, check, or retrieve files. Using the cluster APIs, you can retrieve files from whichever node hosts them. To avoid any single point of failure, it is possible to apply a request to any node of the cluster; there is no master node.
Bitcoinproof creates a forgery-proof timestamp for your data, secured by the Bitcoin network. It allows you to prove that a certain event happened before a certain point in time. Maybe you want to prove that the damage in your flat already existed when you moved in, or that you were in possession of a great artwork before it was published, proving you are the author.
Shasplit takes a large data block, splits it into smaller parts, and puts those parts into an SHA-based content-addressed store. Reassembling those parts is a trivial "cat" invocation. Repeating parts (e.g., from previous split operations) are stored only once, which allows efficient incremental backups of whole LVM snapshots via Rsync. Shasplit shows its strengths on encrypted block devices, but might be useful for non-encrypted data, too.
LiPPGen, the Literate-Programming-based Presentation Generator, takes a standard Literate Program (with LaTeX as the documentation language) as input and lets the instructor comfortably generate presentation slides for each code chunk. It then assembles the provided slide texts and the code chunks and turns them into a browser-based presentation. The presentations feature scrollable code chunk listings, primitive syntax highlighting, and line breaking within listings. LiPPGen expects the source file to be formatted in noweb's Literate Programming style.
