This project is all about accurately driving brushless motors, for cheap. The aim is to make it possible to use inexpensive brushless motors in high performance robotics projects. You need one or two brushless motors, quadrature incremental encoder(s), and a power resistor.

ODrive - High performance motor control

Curve implements the CurveZMQ elliptic curve security mechanism, for use in ZeroMQ applications. This library is primarily a reference implementation for the CurveZMQ specification but may also be used for end-to-end security. CurveZMQ creates encrypted sessions ("connections") between two peers using short term keys that it securely exchanges using long term keys. When the session is over, both sides discard their short term keys, rendering the encrypted data unreadable, even if the long term keys are captured. It is not designed for long term encryption of data.

gwsocket is a simple, standalone, language-agnostic, RFC6455 compliant WebSocket Server, written in C. It sits between your application and the client's browser, giving fast bidirectional communication between these two with ease and flexibility. Very simple, just redirect the output from your application (stdout) to a file (named pipe) and let gwsocket transfer the data to the browser — That's it.

DBMail is a collection of programs that enables email to be stored in and retrieved from a database. It is scalable. You can run the dbmail programs on different servers talking to the same database(cluster). LDAP integration allows you to integrate with existing authentication backends, such as ActiveDirectory.

YottaDB's diverse feature set as a NoSQL multi-level, key-value data store provides users and businesses with a strong foundation for their critical applications. It operates using a daemon-less engine. Unlike most high-end transactional database engines, YottaDB uses Optimistic Concurrency Control (OCC) to implement ACID transactions. Since transactions do not typically collide, optimistic techniques scale up better than pessimistic techniques such as locking.

YottaDB - Rock solid, Lightning Fast. Secure database

Solanum is an IRCv3 server designed to be highly scalable. It implements IRCv3.1 and some parts of IRCv3.2.

CVS is a version control system, an important component of Source Configuration Management (SCM). Using it, you can record the history of sources files, and documents. CVS is a production quality system in wide use around the world, including many free software projects. 
 <ul><li>It can run scripts which you can supply to log CVS operations or enforce 
 site-specific polices.</li><li> Client/server CVS enables developers scattered by geography or slowmodems to function as a single team. The version history is stored on
a single central server and the client machines have a copy of all the files that the developers are working on. Therefore, the network between the client and the server must be up to perform CVS operations
(such as checkins or updates) but need not be up to edit or manipulate the
current versions of the files. Clients can perform all the same
operations which are available locally.</li><li>In cases where several developers or teams want to each maintain
their own version of the files, because of geography and/or policy,
CVS's vendor branches can import a version from another team
(even if they don't use CVS), and then CVS can merge the changes from
the vendor branch with the latest files if that is what is desired. </li><li>
Unreserved checkouts, allowing more than one developer to work on
the same files at the same time.</li><li>CVS provides a flexible modules database that provides a symbolic mapping of names to components of a larger software distribution. It
applies names to collections of directories and files. A single
command can manipulate the entire collection. </li></ul>

Devil-Linux is a CD-based Linux distribution for firewalls and routers. The goal of Devil-Linux is to have a small, customizable and secure Linux. Its main purpose is to be used as server for many applications. It doesn't have any GUI or XServer related stuff. It is mainly targeted for Sys Admin. 

 It could boot from CDROM or USB flash drive. The configuration could be saved in floppy or USB pen drive as the CDROM is read only. It has IPTables / Netfilter support connection tracking for firewalls. It does have facilty to create customized version of the Linux to suit your needs. User could add packages on their own preference. 

 Most of the code is complied using GCC. Kernel level security like chroot restrictions is provided by GRSecurity. Since graphical support is not available, the system requirement is very less. It could run loads of server related applications. 

 Devil Linux suits for Proxy Server, DNS Server, FTP Server, File Server, DHCP Server, Mail Server, HTTP Server and other server related application. Source code location: <A HREF="http://sourceforge.net/projects/devil-linux/" target="_blank">http://sourceforge.net/projects/devil-linux/</A>

GNU nano is a command-line text-editor, with syntax highlighting for many languages, an experimental undo/redo system, regular expression help support, auto-indent support, and many other otpions. Full customizable by a file conf and bindings. Particularity of keyboard shortcuts for standard actions (save, quit, search/check/replace). GNU nano is designed to be a free replacement for the Pico text editor, part of the Pine email suite.
