simpleJ emulates a simplified computer on your PC: a retro-style video game console that lets you understand how a computer works and write your own video game programs. The first microcomputers were quite simple. They had a few kilobytes of memory and couldn't run large programs. Many didn't even have an operating system. Yet they had something valuable: understanding everything about their hardware and software was easy. simpleJ aims to make this possible while running on modern PC hardware.
sipsak is a command line tool for performing various tests on Session Initiation Protocol (SIP) applications and devices. It can make several different tests, send the contents of a file, and interpret and react on the responses. It supports (de-) registration with given contact URIs and digest authentication.
siqqel is a simple and lightweight framework which allows you to execute MySQL queries directly from your browser (by transforming them into JSON calls to a backend script), displaying the results of your queries within the structure of the calling HTML document. To issue a query and have its results displayed in a table of your HTML document, you simply put an SQL statement into the "sql" attribute of a <table> element and it will be executed when you open the HTML document in your browser. Your browser will wrap the SQL statement into a JSON call, and this call will be issued to a backend script on your server, which in turn issues the statement against your database server and returns the result set back to your browser. Your browser will display the result set in the according table. If you hover your mouse over the table, a "reload" icon will be displayed, allowing you to re-issue the SQL statement without the need to reload the whole page.
skiTunes is a fast, extensible alternative to iTunes. It can use Apple Quicktime, VLC, MPlayer, LAME, and cdrecord. It differs from Apple's offering in that it is written in Cocoa and uses native widgets, as well as supporting formats iTunes doesn't, such as OGG and WMA. Using native widgets will allow it to automatically match the rest of the OS when a theme is applied, unlike iTunes, which requires hacking in order to make it match. It will also offer a skinnable "mini- mode".
skill sends signals to processes given any combination of user names, ttys, commands, and pids. snice changes the priority of processes (given the same). They are similar to kill(1) and renice(8), but the commandline is order-independent. There are also verbose, search, and interactive modes of operation.
skipfish is a high-performance, easy, and sophisticated Web application security testing tool. It features a single-threaded multiplexing HTTP stack, heuristic detection of obscure Web frameworks, and advanced, differential security checks capable of detecting blind injection vulnerabilities, stored XSS, and so forth.
skyviewer is an OpenGL-based program to display HEALPix-based skymaps, saved in FITS format files. The loaded skymaps can be viewed either on a 3D sphere or as a Mollweide projection. In either case, realtime panning and zooming are supported, along with rotations for the 3D sphere view, assuming you have a strong enough graphics card.
