Free language software for linux

Russian Language Learning is a Java application that helps you to learn Russian using the Leitner system.

Memorizing words and phrases will not only be more efficient, but the system is a joy to use. Each card also has the phrase spoken by a native russian speaker, to help with pronunciation.

The Leitner system is a way of progressively learning words by placing them in stacks. The words you know are placed in stacks seperate from the words that are still troubling you, for more efficient learning.

And there is one other thing about Tanooshka.com language learning. Each set of cards, are the words to a movie, so when youve learned the set of words, you can watch the movie, and understand it! In Russian!

The Assembly Language Debugger is a tool for debugging executable programs at the assembly level. It currently runs only on Intel x86 platforms.
Operating systems supported: Linux, FreeBSD, NetBSD, OpenBSD
Main features:
- Step into / Step over
- Breakpoints
- Powerful ELF format interpreter
- Easy memory manipulation
- Disassembler for intel x86 instructions
- Easy register manipulation
Enhancements:
- added commands: display, ldisplay, undisplay to dump specified memory locations after each single step (thanks to ziberpunk < ziberpunk =at= ziberghetto dhis org > for the suggestion and code)
- all Makefiles are now based on automake in the hopes that this will fix some of the problems integrating ald into the *BSD ports systems
- bug fix where a pointer wasnt set to NULL after clearing program arguments with the "set args" command
- this is related to the previous feature: if the effective address lies inside a symbol/function, the corresponding symbol is now displayed
- for CALL and JMP instructions, exact target/effective addresses are now computed (code for this was contributed by Samuel Falvo II < kc5tja =at= arrl net >)
- upgraded all configure scripts to autoconf v2.59

SML is a "toy" machine language intended to teach basic processor concepts. This website contains an explanation and definition of SML, as well as an interpreter and example SML programs. GPLd source code for the interpreter is available, as well as binaries for Windows and Linux.

A machine language defines a set of instructions that a CPU can execute to perform operations. In other words, a machine language defines what you can do with your computer. Modern processors have very complex instruction sets; however, the simple language described here can give you an understanding of what is happening "under the hood" with your computer.

Machine language is the actual data that is directly run by the processor. Writing a program in machine language can therefore be advantageous if you need to save space or highly optimize your code. However, machine language is also not portable and can be difficult to understand and maintain.

Therefore, almost all code is now written in a higher level language, such as C, C++, Java, or scripting languages such as shell or perl. These languages all have their advantages and disadvantages as well, such as varying levels of portability, maintainability, scalability, and execution speed.

One level higher than machine language is assembly language. Assembly language is basically readable machine language. Instead of writing out the code bit-by-bit, you write out the code as a sequence of human readable instructions, which are then compiled almost directly into machine language.

Assembly language is almost always used instead of machine language when such a direct level of control is needed. For example, some games implement part of their code in assembly in order to maximize execution speed. Assembly can be "inlined" into some higher level languages, like C. This means that the assembly is defined as a callable procedure from within the C code.

jsPro is a set of libraries that extend the core Javascript classes and provide a number of new classes.

The aim is to provide a rich set of object-based functionality to the Javascript language.

sdlBasic is a small and efficient basic interpreter aimed to game creation in the spirit of the old and glorious AMOS.
Enhancements:
- fixed bug with debug inspect variables
- fixed bug of return os :now return linux win32 or osx
- added some part of requested names commands
- added do loop control structures

X Language is a new multi-syntax programming including a portable set of APIs to create console or graphical applications runnable on many platforms (UNIX/X11, Win32, ...). X Language comes with an interpreter, a compiler and a debugger.
X Language is publicly available under the GPL.
Installation
- tar -xzf xlang-0.7.1.tar.gz
- cd xlang-0.7.1
- ./configure
- make
- make install
- ./xlc calc.xc
Enhancements:
- Adding LANG/MATH specifications
- Adding SYS (basic) specifications
- Start implementing the SCR API

A free IDL (Interactive Data Language) compatible incremental compiler (ie. runs IDL programs). IDL is a registered trademark of Research Systems Inc.
Full syntax compatibility with IDL 6.0
ALL IDL language elements are supported, including:
- Objects,
- Pointers,
- Structs,
- Arrays,
- System variables,
- Common blocks,
- Assoc variables,
- All operators,
- All datatypes,
- _EXTRA, _STRICT_EXTRA and _REF_EXTRA keywords...
The file input output system is fully implemented
(Exception: For formatted I/O the C() sub-codes are not supported yet)
netCDF files are fully supported.
HDF files are partially supported.
Basic support for HDF5 files.
Overall more than 240 library routines are implemented. For a sorted list enter HELP,/LIB at the command prompt and look for library routines written in GDL in the src/pro subdirectory.
The WRITEFITS procedure and the READFITS function from the IDL Astronomy Users Library compile and run under GDL.
Graphical output is partially implemented. The PLOT, OPLOT, PLOTS, XYOUTS and TV commands (along with WINDOW, WDELETE, SET_PLOT, WSET, TVLCT) work (important keywords, some !P system variable tags and multi-plots are supported) for X windows and postscript output.
GDL has an interface to python.
No GUI support (widgets) is implemented so far.
GDL is free software licensed under the GPL

Short Markup Language is an alternative XML notation that is a character by character equivalent with XML.
Short Markup Language covers all legal XML constructs, including processing instructions, doctype declarations, internal DTD subsets and namespace declarations.
Currently SML-to-XML and XML-to-SML converters have been implemented. The converters are based on efficient JavaCC parsers, and can be run from the command-line run or an Ant-task.
Short Markup Language is an open-source project, published under the GNU General Public Licence.
Enhancements:
- First release includes SML to XML and XML to SML converters in an easy to use executable jar.
