se is a screen-oriented version of the classic UNIX text editor ed. The editor implements many of the commands of ed, but instead of being line-oriented, se is screen-oriented. The command syntax is very familiar to users who already know ed. If you get stuck, there is a built-in help system that describes many of the available commands. Many configurable options can be loaded from a .serc file. se can be run interactively or in a script via the included scriptse utility. The editor is portable across many platforms, supporting major Linux and BSD distributions as well as other systems like GNU, Minix, Haiku, OpenSolaris, and Cygwin.
phalanx computes a digest of many buffers simultaneously, and produces a combined hash of them all. It is an initiative to provide a fast, simple, and portable alternative method to compute a checksum in a parallel fashion. It has options for I/O buffer size, hash width, number of threads, and more. It can be run single-threadedly for performance comparisons. It can check files against previously-saved sums, like "MD5sum" does. It also has a "demo" mode, to ascertain accurate operation. It is intended to be useful on large files and multicore/multiprocessor/multithreaded environments.
RSound is a simplistic and lightweight framework for networked TCP/IP audio. It is designed to be very simple to implement, and to work well with music and video players. A librsound is supplied. It is not designed for low latency audio (games), and lets the sound backend take care of sound mixing. It supports POSIX-compliant systems (including cygwin). It includes audio output support for ALSA, OSS, libao, and PortAudio.
Twibright Registrator removes noise and can quadruple the resolution of a camera in software by matching several pictures together. It can be applied to remove noise, JPEG artifacts, rain, CRT stripes, and passersby. It can enhance night photos and provide the effect of long exposure in daylight. Pictures are matched by removing shift, rotation, zoom, and brightness changes. It features high performance bilinear interpolation, automatic adaptive corrective deconvolution, 32-bit float depth, photometrically linear space, and 16-bit depth PNG output.
TCL2FTP is an extension library for Tcl scripts which allows Tcl programs to perform FTP client and gateway actions. It fully supports the FTP/FXP protocols, is ready for use with SSL/TLS, and is compatible with glFTPd. It can run simple FTP commands, and it supports 25 simultaneous FTP sessions.
ratproxy is a semi-automated, largely passive Web application security audit tool optimized for accurate and sensitive detection, and automatic annotation, of potential problems and security-relevant design patterns based on the observation of existing, user-initiated traffic in complex Web 2.0 environments.
