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.
GetData is a library that provides an API to interface with dirfile databases. The dirfile database format is designed to provide a fast, scalable format for storing and reading binary, synchronously-sampled, time-ordered data. GetData was originally written for the BOOMERanG and BLAST experiments as a data format suitable for use for both quick-look and data reduction. It is now used by many other cosmological and astrophysical experiments including ACT, Planck, Spider, Keck, as well as other projects.
The parallel project allows for simple parallel and distributed processing from shell scripts. In particular, the programs accept lines of shell code on the standard input and run these lines in parallel. The parallelism can be either on the local machine or on a cluster, if a small amount of time is taken to set up SSH. Additionally, the distributed version includes a degree of fault tolerance.
Evergreen is a cross-platform development environment that tries to be lightweight and language-agnostic yet functional. It started as a project to reimplement Rob Pike's Acme editor for Plan 9 in Java, but has since evolved in directions that help it deal with large codebases and multiple projects/branches at once. Remaining similarities include the tiled windows and the Unix-like reliance on external programs rather than reinventing every wheel. The major philosophical differences include strong support for keyboard-based editing, language-specific functionality, and native platform UI conventions. There are also two new guiding principles: accepting regular expressions and output diffs.
