Untarka extracts TAR (Unix Tape ARchive) files without calling any external programs. It supports and autodetects multiple compression methods (.tar, .tar.Z, .tar.gz, .tar.bz2, .Z, .gz, and .bz2). Unix devices, sockets, hard links, symlinks, owners, and permissions are ignored during extraction.

usb4java is a Java library for accessing USB devices. The low-level part is based on the native libusb 0.1 shared library and reflects this API as completely as possible. Java NIO buffers are used for data exchange between libusb and Java. The high-level part implements the javax.usb standard (JSR-80). Supported platforms are Linux (x86 32/64 bit), Mac OS X (x86 32/64 bit, PowerPC 32 bit) and Windows (x86 32/64 bit), but other platforms supported by Java 6 and libusb may work 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.
