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.
uBeeDisk is a tool that copies disks and images from one to another. It was developed to archive Microbee disk images from floppy disks and to write them back to floppy, but other disk formats can be added. It is intended mainly for users of computer emulators. As the program makes use of the 'LibDsk' library there are many options for image types. The program provides some data recovery methods along with 'info' files for each disk image file created. An 'info' file contains information about the disk image, a status map of all sectors read from the disk, and an MD5 stamp of the associated disk image.
uCal is a PHP class that can be used to convert dates between the Hijri and Gregorian calendars. It features the ability to convert dates between Hijri and Gregorian calendars and vice-versa. It is fully compatible with Umm Al-Qura. Dates formatted like the PHP date() function can be returned. English/Arabic formatted Hijri and Gregorian dates and times can be output. Versions of the date() and mktime() functions for Hijri are also provided.
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.
uberSVN is an enhanced distribution of Apache Subversion that lets developers choose any combination of software development tools that best fits the business requirements in hand. Toolset choice can be based on price or functionality or the use of open source or closed, proprietary applications. There is no vendor lock-in. The product is available at no cost, but professional support is available for purchase from WANdisco.
udp_copy2 consists of two executables, udp_send2 and udp_recv2, implementing plain text non-interactive data transfer over UDP/IPv4 with a preset transfer rate. On lossy links, it yields better throughput than TCP-based transfers. It may also be used for smooth user space throttling. It dedicates a mode to SNAT/MASQ so the receiver can initiate transfer from behind a firewall. It features a very precise user space packet scheduler. It handles SIGSTOP in a rational way. It only transfers in one direction for one invocation. It needs and uses no synchronous I/O multiplexing. Shell access is required on both ends. The package also contains the auxiliary multi-threaded tool "bigpipe", which can be used to reduce pipeline latency.
