FM is a Gtk+ file manager which aims to offer the best possible ratio between features, simplicity, and resource usage. Currently all the efforts have gone to the development of the browser. Much thought has been put into the creation of an efficient and easy-to-use interface. Several existing file managers on a variety of platforms have been used as an inspiration and lots of new and original features have been added. File operations are not yet possible, but will soon be supported through a modular interface that will allow anyone to extend and customize Fm.
Fl_Editor is a word-wrapping text editor widget for the FLTK toolkit. It supports CUA-style editing keys, automatic scrollbar display, load and save to file or buffer, and more. Fl_Editor includes subclasses with status and position display, find and replace, a couple of utility widgets, a status panel and a progress bar that can be used independent of any of the editors.
Flwm is an X window manager designed to be user friendly and use the absolute minimum amount of screen real estate. It has no icons, using a pop-up menu to select hidden or new windows, and sideways titlebars. Flwm is also designed to achieve Gnome, KDE, and Motif compatibility simultaneously and has also been tested with many SGI programs that normally require 4DWM.
Flux consists of utility APIs that apply compression and strong cryptography to I/O channels (file or network), do strong hashing, and exchange C structs in an architecture-independent fashion. It also provides n-ary trees whose contents can be serialized to human-readable files or network streams, along with some related utilities. It is written in C and integrates with the GLib main loop.
Fluid Streaming Server is a program for streaming MP3 audio over the Internet or any other TCP/IP-based network. Some of the features of the server include transmission of an MP3 stream from a predefined playlist (m3u format), relaying a stream from another server creating a network of servers, listening to a port for an incoming stream and broadcasting it, and using telnet to connect to the server and get information about the connected clients and current song playing. Provided is an Applet that will display the name and other information of the song the server is currently broadcasting.
FLTK (pronounced "fulltick") is a cross-platform C++ GUI toolkit for UNIX/Linux (X11), Microsoft Windows, and Mac OS X. It provides modern GUI functionality without the bloat, and supports 3D graphics via OpenGL and its built-in GLUT emulation. FLTK is designed to be small and modular enough to be statically linked, and also works fine as a shared library. It also includes an excellent UI builder called FLUID that can be used to create applications in minutes.
The Free Library System (FLS) is a system for maintaining a database of items and borrowers of a library. The goal is to provide simple yet powerful and flexible ways to search for items, provide circulation functions, and communicate with other libraries running FLS. It is implemented in Java and uses JDBC to access a suitable database.
