usb4java is a Java library for accessing USB devices. It is based on the native libusb 1.0 library and uses Java NIO buffers for data exchange between libusb and Java. It also supports the javax-usb standard (JSR-80) through the usb4java-javax extension. Supported platforms are Linux (x86 32/64-bit, ARM 32-bit), OS X (x86 32/64-bit), and Windows (x86 32/64-bit). Other platforms may work as well (as long as they have at least Java 6 and are supported by libusb) by compiling the JNI library manually.
uvlan is a User-space Virtual Local Area Network. In other words, uvlan peers act as nodes on a network switch. Ethernet traffic is routed between peers intelligently. This allows for multiple networks to share resources and even IP address space. Some may call it a VPN (Virtual Private Network) application, but it's much more powerful: it is peer-to-peer, is much simpler, and operates at layer 2 (ethernet). VPNs generally operate at layer-3 (IP), and layer 2 applications like gaming can't be supported with layer 3 tunneling.
vTemplate is a PHP class that is intended to make splitting PHP from HTML a simple and natural task. It has easily understandable syntax that is much easier to use than other template classes. It compiles a template into native PHP code using one PCRE call, thus the parsing is extremely fast. It also has powerful caching and debugging classes to extend the functionality.
validator.py is a tool for ensuring that data conforms to certain sets of rules, called validations. A validation is essentially a schema for a dictionary, containing a list of rules for each key/value pair in the dictionary you want to validate. This is intended to fill a similar use case to form validations in WTForms or Rails, but for general sources of data, not just Web forms.
