Figaro's Password Manager (FPM) is a GNOME application that allows you to securely store your passwords, which are encrypted with the blowfish algorithm. It allows you to copy passwords or usernames to the clipboard or primary selection. If a password is for a Web site, FPM can keep track of the URLs of your login screens and can automatically launch your browser. You can also teach FPM to launch other applications. FPM can sort your passwords into categories. Finally, it has a password generator that can help you choose good passwords.
FIDOGATE is a Fido-Internet gateway and a Fido tosser. The gateway converts between the worlds of Fido NetMail/EchoMail (or FTNs, Fido Technology Networks in general) and the UNIX mail/news system. FIDOGATE will convert Fido mail packets to RFC822/1036-style messages and vice versa.
Ficl (Forth inspired command language) is an ANS Forth interpreter written in C. Unlike traditional Forths, this interpreter is designed to be embedded into other systems as a command/macro/development prototype language. Ficl provides object extensions that can be used to wrap methods and structures of the host system without altering them.
Fiasco is a microkernel with real-time capabilities running on the x86 and ARM platforms. It is compatible with the L4 microkernel, which has set standards in microkernel performance and functionality. Fiasco is a fully-featured and secure L4 implementation with excellent real-time properties. It can run L4Linux, a port of the Linux kernel to the L4 interface which executes completely in user mode. The screenshot shows the DOpE real-time windowing environment running on top of Fiasco, with an instance of L4Linux running in one of the windows.
fhttpd is an FTP/HTTP server with modules support. Modules run as separate "looping" processes locally or remotely, and can be configured to run under separate userids. Locally running modules can be configured to use fd passing of client's connection to avoid overhead in sending the response. ~username URL to directory remapping is supported in HTTP, and can be configured to access files, run scripts and modules under mapped user's userid.
FFTW is a fast C FFT library. It includes complex, real, symmetric, multidimensional, and parallel transforms, and can handle arbitrary array sizes efficiently.It is typically faster than other freely available FFT implementations, and is even competitive with vendor-tuned libraries (benchmarks are available at the homepage). To achieve this performance, it uses novel code generation and runtime self optimization techniques (along with many other tricks).
