StelsEngine is a fast in-memory SQL engine (in-memory JDBC) for storing and processing tabular data in Java applications.
Using StelsEngine, you can make processing data in your software considerably easier and quicker. StelsEngine is as easy to use as possible since it implements the JDBC API standard.
In the process of developing software applications, developers often encounter various tasks related to processing tabular data arrays.
For example, such tasks as calculating maximums or sums, using search, applying sorting, etc. StelsEngine is convenient to deal with such tasks by using the classical SQL - language for processing relational data that has been universally used in a lot of popular DBMSs for decades.
But unfortunately, Java Development Kit does not provide software developers with standard classes for processing data with the help of SQL. Here you can find collection classes, such as Hashtable, Vector etc. that are rather difficult to use directly for this type of tasks.
To solve this problem, StelsEngine was developed. It makes it possible to effectively process data with the help of SQL (Click here for the example of the StelsEngine use).
Our products StelsCSV and StelsDBF JDBC drivers are fully based on the StelsEngine technology.
Main features:
- It is JDBC Type 4 driver
- It supports most keywords of ANSI SQL92
- It supports integer, floating point, string and date/time data types
- It supports handling of custom Java objects and classes
- It supports aggregate, converting, string and other SQL functions
- It supports user-defined SQL functions
- It supports data loading from a DBMS
- It is a platform independent
Enhancements:
- This version supports swapping mode for large tables.

Euphoria is simple, flexible, and easy to learn. The project outperforms all popular interpreted languages. Complete Reference Manual included. Lots of free example programs with full source. Makes .EXE files.
Theres also a Euphoria To C Translator that gives really high speed. An easy-to-use database system is also included. The Web site has over 1200 contributed Euphoria programs with source.
Main features:
- Euphoria programs run on Windows, DOS, Linux, and FreeBSD.
- The language is flexible, powerful, and easy to learn.
- There is no waiting for compiles and links - just edit and run.
- You can create and distribute a royalty-free, stand-alone .exe file.
- Dynamic storage allocation is fundamental to Euphoria. Variables grow or shrink in size without the programmer having to worry about allocating and freeing chunks of memory. Elements of an array (Euphoria sequence) can be a dynamic mixture of different types and sizes of data.
- Euphoria provides extensive run-time error checking for: out-of-bounds subscripts, uninitialized variables, bad parameter values for library routines, illegal value assigned to a variable, and many more. If something goes wrong youll get a full error message, with a call traceback and a listing of variable values. With other languages youll typically get protection faults with useless dumps of machine registers and addresses.
- The Euphoria interpreter is more than 30 times faster than either Perl or Python, and its considerably faster than all other interpreted languages, according to the "Great Computer Language Shootout" benchmark (see demobenchbench.doc).
- If that isnt enough, theres a Euphoria To C Translator that can translate any Euphoria program to C, and boost your speed even more. Why waste time debugging hand-coded C/C++? You can easily develop a Euphoria program, and then generate the C code.
- Euphoria programs are not constrained by any 640K memory restrictions for which MS-DOS is infamous. All versions of Euphoria let you use all the memory on your system, and if that isnt enough, a swap file on disk will provide additional virtual memory.
- An integrated, easy-to-use, full-screen source-level debugger/tracer is included.
- Both an execution-count profiler, and a time profiler are available.
- There is a large and rapidly growing collection of excellent 3rd party programs and libraries, most with full source code.
- RDS has developed an extremely flexible database system (EDS) that is portable across all Euphoria platforms.
- The WIN32 implementation of Euphoria can access any WIN32 API routine, as well as C or Euphoria routines in .DLL files. A team of people has developed a Windows GUI library (Win32Lib), complete with a powerful Interactive Development Environment. You can design a user interface graphically, specify the Euphoria statements to be executed when someone clicks, and the IDE will create a complete Euphoria program for you. There are Windows Euphoria libraries for Internet access, 3-D games, and many other application areas.
- The DOS32 implementation of Euphoria on MS-DOS contains a built-in graphics library. If necessary, you can access DOS software interrupts. You can call machine-code routines. You can even set up your own hardware interrupt handlers. Many high-speed action games, complete with Sound Blaster sound effects, have been developed 100% in Euphoria, without the need for any machine code.
- The Linux and FreeBSD implementations of Euphoria let you access C routines and variables in shared libraries, for tasks ranging from graphics, to X windows GUI programming, to Internet CGI programming. The good news is, youll be programming in Euphoria, not C.
- A complete open source (Public Domain) Euphoria interpreter, written in Euphoria, is included in the download package. It can execute any Euphoria program on any platform. An optional high-performance C-coded back-end for this interpreter is available for just $79. See the Source License.

ButterFlight is a new wonderful game for Linux! You play on the glade that is filled with the multicolored butterflies. At every round, you have to collect a certain number of butterflies of a particular color on the glade.

You can flip and rotate the butterflies sitting there - try to bring those of the same color together. They will fly away, freeing the place that will be filled with the new butterflies. There are four different game modes.

Swap butterflies so that you could collect 3 or more butterflies of the same color together. White Butterfly matches the butterfly of any color. To pass to the next level - collect definite butterflies (number and color are denotedin the bottom-left corner).

You are the Lord of the Butterflies. An evil witch has imposed spell on you and you lost your wings. To weave the new wings you have to collect a great number of different butterflies. Your little friends wanted to help you, but to make sure that you are really their lord, the butterflies decided to put you to the test. You should do all your best to win their
confidence. The family of your courtiers, who believe in you, will help you to make up the combination from any type of the butterflies.

You play on the glade that is filled with the multicolored butterflies. At every round, you have to collect a certain number of butterflies of a particular color on the glade. You can flip and rotate the butterflies sitting there - try to bring those of the same color together. They will fly away, freeing the place that will be filled with the new butterflies. The move is only possible if the result of it is the good combination, that is some butterflies will fly away from the field.

The type of the butterflies you have to collect, as well as their number, is indicated in the Left section. You can also see the number of possible moves there. You may use the Auto button to make the computer play the next good move - but youd get no points for it.

There are four different game modes: Pairs, Twins, Quads and Triads.

In Pairs and Twins, you can interchange two neighboring butterflies; you should collect a straight line of three or more similar butterflies, to make them fly.

In Quads and Triads, you can rotate groups of four or three butterflies respectively, either clockwise (with left mouse button) or anti-clockwise (with right mouse button). If you manage to collect four or more butterflies of the same type together (not necessarily in one row) they will fly.

Be the true Lord of the Butterflies! Good luck!
