cmus is a small, fast, and powerful console music player for Linux and *BSD. It supports almost all common file formats, SHOUTcast/Icecast streaming, and multiple output plugins. cmus features multiple media library views, a playqueue, a directory browser, powerful filters, and vi-style search and keybindings. It also features gapless playback, ReplayGain, Unicode support, and customizable color schemes.
vlock is a program to lock one or more sessions on the Linux console. This is especially useful for Linux machines which have multiple users with access to the console. One user may lock his or her session(s) while still allowing other users to use the system on other virtual consoles. If desired, the entire console may be locked and virtual console switching disabled.
ted (Tiny EDitor) is a lightweight commandline text editor designed for scripting. It's intended to be an easier-to-use alternative to "ed". It is lightweight, scriptable, and easily harnessed by shell scripts, but doesn't suffer from the chronic user-unfriendliness that characterizes ed. It is also slightly more featureful than ed, and includes multiple editing buffers and built-in script handling.
JCGO (pronounced as "j-c-go") translates (converts) programs written in Java into platform-independent C code that can be compiled (by third-party tools) into highly-optimized native code for the target platform. JCGO is a powerful solution that enables your desktop, server-side, embedded, mobile, and wireless Java applications to take full advantage of the underlying hardware. In addition, JCGO makes your programs, when compiled to native code, as hard to reverse engineer as if they were written in C/C++. The JCGO translator uses some optimization algorithms that allow, together with optimizations performed by a C compiler, the resulting executable code to reach better performance compared with the traditional Java implementations (based on the Just-In-Time technology). The produced executable does not contain nor require a Java Virtual Machine to execute, so its resource requirements are smaller than that required by a typical Java VM. This also simplifies the process of deployment and distribution of an application.
Rho is a small, very powerful console-based POSIX text editor and mini-IDE with Bash/Emacs key bindings. A configuration file allows the user to create macros using not only any internal function but anything available to a shell command. Keyboard macros (Ctl-Alt-A through Z) can be sourced into the editor for each kind of task, the next sourcing overwriting the last. Rho also allows an unlimited number of templates (sh, awk, python, etc.) to be injected into executable buffers which trap stdout and stderr.
