uBee512 emulates all of the Microbee Z80 series of microcomputers, including ROM, Floppy and Hard disk-based models. Up to 2MB of extended memory is supported. The optional on board sn76489 sound IC is also emulated. The display may use SDL or OpenGL video rendering. Z80 PIO emulation includes tape, speaker, RTC, serial to PC RS232, and mouse peripherals. Parallel port peripherals include BeeThoven (AY-3-8910), BeeTalker (SP0256-AL2), Compumuse (SN76489), DAC, printer, and joystick. Many disk image types and floppy disks are supported. A joystick may be optionally mapped to keys. A large number of options are available as well as a built in OSD console.
uNabto is a small UDP-based NAT and firewall traversing virtual Web server. It is useful for very small resource limited embedded systems. It works by installing a free Nabto protocol plugin in your browser which, in combination with a "HTML-device driver" definition file, communicates and presents the user with a nice Web based GUI.
uWSGI is a fast, sysadmin-friendly application server container, meant for professional deployment and development of Python, Perl, Ruby and Lua Web applications. It features multiple apps in a single process, advanced logging, sendfile(), memory reports, an integrated profiler, vector based I/O, self-healing, and a lot more.
ucpp is a C preprocessor. It is designed to be quick and light, but still fully compliant to the ISO standard 9899:1999, also known as C99. ucpp can be compiled as a stand-alone program or linked to some other code; in the latter case, ucpp will output tokens, one at a time, on demand, as an integrated lexer. ucpp operates in two modes: in lexer mode, ucpp is linked to some other code and outputs a stream of tokens where each call to the lex() function will yield one token; in non-lexer mode, ucpp preprocesses text and outputs the resulting text to a file descriptor. If linked to some other code, the cpp() function must be called repeatedly, otherwise ucpp is a stand-alone binary.
uhub is a high performance peer-to-peer hub for the ADC network. Its low memory footprint allows it to handle several thousand users on high-end servers, or a small private hub on embedded hardware. It uses the ADC protocol, and is compatible with DC++, jUCy, and other ADC clients.
Uldramar is a fantasy RPG and adventure game. You can cast spells like the mushroom morph spell and pick up objects for later use. The story is about a plane called Uldramar where there is a quest or two waiting for you. The game was influenced by the Ultima series and the Legend of Zelda.
