SpeedyCGI (aka PersistentPerl) is a way to run Perl scripts persistently, which usually makes them run much more quickly. Converting scripts to use SpeedyCGI is in most cases as simple has changing the interpreter line at the top of the script. After the script is initially run, instead of exiting, SpeedyCGI keeps the Perl interpreter running in memory. During subsequent runs, this interpreter is used to handle new requests, instead of starting a new Perl interpreter for each execution.
SteelBlue is an Open Source Web application server similar to Cold Fusion. It extends HTML with tags to execute SQL commands, perform type checking on user input, loop over sections of code, and manipulate data. In addition, it has a Perl-like scripting language that can be embedded directly into the HTML for complex data manipulation. SteelBlue runs as a CGI script on Linux, UNIX variants (via gcc 2.8), and Win32. It includes native support for most popular relational databases and the embedded scripting language is extensible though a C++ API. Included in the distribution are a book about programming SteelBlue, many examples, and a full bulletin board application.
STklos is a free Scheme System conforming to R5RS. The implementation is based on an ad-hoc Virtual Machine. It can also be compiled as a library, so that one can easily embed it in an application. Its features include an efficient and powerful object system based on CLOS, a simple-to-use module system, implementation of the full tower of numbers defined in R5RS, and easy connection to the GTK+ toolkit. STklos is the successor of STk, a Scheme interpreter tightly connected to the Tk toolkit.
Tcl provides a portable scripting environment for Unix, Windows, and Macintosh that supports string processing and pattern matching, native file system access, shell-like control over other programs, TCP/IP networking, timers, and event-driven I/O. Tcl has traditional programming constructs like variables, loops, procedures, namespaces, error handling, script packages, and dynamic loading of DLLs. Tk provides portable GUIs on UNIX, Windows, and Macintosh. A powerful widget set and the concise scripting interface to Tk make it a breeze to develop sophisticated user interfaces.
The Glasgow Haskell Compiler is a robust, fully-featured, optimising compiler for the functional programming language Haskell. GHC compiles Haskell to either native code or C. It implements numerous experimental language extensions to Haskell for example concurrency, a foreign language interface, several type-system extensions, exceptions, and so on. GHC comes with a generational garbage collector, a space and time profiler, and a comprehensive set of libraries.
TinyScheme is a lightweight Scheme interpreter that implements as large a subset of R5RS as possible without getting very large and complicated. It is meant to be used as an embedded scripting interpreter for other programs. As such, it does not offer IDEs or extensive toolkits although it does sport a small top-level loop, included conditionally. A lot of functionality in TinyScheme is included conditionally, and it allows multiple interpreter states to coexist in the same program without any interference between them. Foreign functions in C can also be added and values can be defined in the Scheme environment.
Berkely Logo (ucblogo) is an interpreter for the Logo programming language. Logo is a computer programming language designed for use by learners, including children. This dialect of Logo features random-access arrays, variable number of inputs to user-defined procedures, various error handling improvements, comments and continuation lines, first-class instruction and expression templates, and macros.
