Mercury is a new logic/functional programming language, which combines the clarity and expressiveness of declarative programming with advanced static analysis and error detection features. Its highly optimized execution algorithm delivers efficiency far in excess of existing logic programming systems, and close to conventional programming systems. Mercury addresses the problems of large-scale program development, allowing modularity, separate compilation, and numerous optimization/time trade-offs.
JEL (Java Expressions Library) is a library for evaluating simple single-line expressions in Java. The key feature of JEL is the fact that it is a compiler. The language of JEL expressions resembles the Java Language expressions as close as possible. JEL supports all Java primitive types and classes (even in the form of constants), allows one to call both static and virtual methods of Java classes (with no additinal runtime costs and no wrappers), and performs evaluation of constant subexpressions at a compile time.
GNU Compiler for Java (GCJ) is a portable, optimizing, ahead-of-time compiler for the Java Programming Language. It allows Java source code and byte codes to be compiled to native code. GCJ-compiled applications, when running native, are not subject to many of the performance and memory management challenges that embedded developers face when using the interpreted or just-in-time models.
Pike is an interpreted, object-oriented, dynamic programming language with a syntax similar to C. It includes a powerful modules system that, for instance, has image manipulation, database connectivity and advanced cryptography. It is simple to learn, does not require long compilation passes and has powerful built-in data types allowing simple and fast data manipulation.
PentiumGCC is a branch of GCC (the GNU Compiler Collection, formerly known as gcc/egcs) especially designed to optimize for x86 compatible chips. Speed improvements of 2-30% are possible. MMX support for P-II is being worked on. Since PentiumGCC is distributed as a patch to GCC, you will need to get the source code for the main GCC distribution to compile PentiumGCC.
zJSP is an experimental translator from JavaServer Pages (jsp's) to Java. It is designed to be used in conjunction with Sun's Java Servlet Developers Kit (JSDK), version 2.0. It *should* work with any Java Servlet environment compatible with JSDK servlets. zJSP is implemented as a page compiler, translating JSP pages into Java Servlets, which are then run using a Java Servlet environment.
Sather is an object oriented language designed to be simple, efficient, safe, flexible and non-proprietary. One way of placing it in the "space of languages" is to say that it aims to be as efficient as C, C++, or Fortran, as elegant as and safer than Eiffel, and support higher-order functions and iteration abstraction as well as Common Lisp, CLU or Scheme.
