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.
Mazeman is an original puzzle game, somewhat like "chip's challenge", except that it can generate new randomized puzzles from a carefully-balanced array of elements. The objective is to find the gems amongst the other dynamic maze elements. A very terse and powerful scripting language and an integrated script debugger enable users to generate their own maze designs. Scripts allow new players to acquire skills gently and provide diabolical puzzles for the expert.
LightAdmin speeds application development by bringing a pluggable, fully operational data management backend to JPA-based applications and relieving your codebase for more important things. It allows developers to define a data management backend with POJOs and JPA and customize it using simple Domain-specific language.
ng-jackspa is a set of simple user interface programs that host a LADSPA plugin, providing JACK ports for its audio inputs and outputs, and dynamic setting of its control inputs through the user interface. Additionally, the plugin controls can be exported to or controlled by control voltages on standard JACK audio ports. The following interfaces are available: an ncurses visual (full screen) interface for the terminal; a GTK+ graphical interface; a Qt 4 graphical interface; and a command line interface for the terminal.
ddserver.pl is a simple, small Perl script that acts as a DynDNS-compatible and ZoneEdit-compatible dynamic DNS server. It also provides an HTML Web interface, operating as a CGI script, and has been tested within Apache and lighttpd Web servers. It creates and maintains bind9 named.conf(5) zone files. Simple zone-specific templates and username/password ACLs are supported.
