User manuals. 1.4 million of them and counting. Free for the downloading.
A publisher reprinting rare, forgotten, and unusual texts. Download them as .pdfs or purchase them online. Many categories are represented, from epic sagas to classical fiction, drama to architecture, history to technology.
A free, open source mathematical processing system written in Python.
A basic framework for forcing heap overflow vulnerabilities in the Linux kernel. This is for the purpose of learning to write heap overflow exploits in the Linux kernel as well as for developing the techniques to find and exploit them. It is entirely possible that this library may destabilize the kernel so practice on a virtual machine that you can revert to a known-stable state when you're done.
HybridAuth is a library for web apps which implements social sign-ins (meaning, you authenticate with an existing social network account (like Twitter or Facebook)) rather than applying for an account with an e-mail address. Lets the user import established profiles and contact lists from the socnet account they logged in with. Also has a library of plugins for existing frameworks and applications, from Drupal to Concrete to Wordpress. Written in PHP so that it'll run on just about every webhost out there out of the box.
Zopfli is a new data compression algorithm from researchers at Google which seems to work better than most existing compression algorithms out there. The trade off is that it can take much longer to finish compressing files, but more space and transmission time are saved. It is recommended for compress-once-distribute-many-times use cases.
libSodium is an implementation of DJB's crypto library NaCl which is actually portable - it'll run on many different operating systems (not just a few Unices), it supports parallel processing, and includes all of the conservatively safe crypto primitives that you've come to expect from the original. Optimization and benchmarks are performed at compile time for your platform for maximum portability. Includes bindings for several different languages that NaCl doesn't.
A set of slim Python bindings for the Leap Motion libraries.
A simple to use personal search engine for email. Global search, tag based. Written with the UNIX philosophy in mind - a simple to use tool that can be used to build bigger tools. Has a library interface, too. Indexer, searcher, and interface are three different things. Uses Xapian for the actual indexing.
Headless utility built upon QtWebKit that renders HTML into a PDF or image file. Written in C. Has a library. Build a slightly more complex archive bot for exocortex? Run it on Leandra?
documentation for OSTree, a library and tools for committing, downloading, and stacking downloaded filesystem images in a Git-like fashion. Implements a content addressable datastore. Used for building live distro images, possibly VMs or immutable server images. Atomic upgrades, rollbacks, multiple bootable roots, binary history,
A Linux driver system that allows unprivileged code to implement file systems. Because the file system drivers exist entirely out of kernel space, you can do some pretty crazy things with the file system block layer...
