Free object oriented programming concepts software for linux

The Object Oriented Database Kit is a set of tools to help database applications developers to handle database communication, reporting, and printing. It has a solid, stable, and easy to use API. The project is also GUI toolkit agnostic and portable.

Qu is a powerful full-featured object oriented programming language. It is an Open Source software. The Qu Programming Language is absolutely free (as in free lunch) and distributed under the GNU General Public License (GPL).
Qu is inspired by other languages. Most noticeably Perl, Python, Ruby and C. It mostly resembles Python except that the syntax is more flexible, the internals are simpler, and Qu allows you to use either indentation or non-indentation style.
Qu has a clean syntax designed to promote readability. There is no need for semi-colons and commas to separate items except in rare cases when the end of an expression is not obvious.
Qu is a procedural language. A program consist of statements and expressions evaluated in the order they appear.
Qu is a strong semi-dynamic (optional-static) typing language. Adding a number to a string will throw an exception. A variable can hold anything or you can attach a validator to it. Validators can be as simple as a class, a constant object (Array, Range, Struct, etc.) or even a validator function.
Arrays, dictionaries, and sets can be constrained to hold only a specific "type" of data as well.
Everything in Qu are objects, including numbers, strings, etc. The number 123, for example, is actually an instance of the builtin Int class. Classes are instances of the builtin Class class, etc. But this does not mean that you must write your programs in an object oriented manner. That is entirely up to you.
Documentation can be embedded in the source code. The compiler will skip them. The documentation builder will extract them. The builder is included as part of the standard distribution.
In fact, when you install Qu or Qu modules, the documentations are automatically built for you.
Qu is entirely written in C. Readable documentations are embedded in the C sources directly.
Writing C modules for Qu is as easy as it can get!

Free Pascal (aka FPK Pascal) is a 32 or 64 bit (from 1.9.6) pascal compiler. Free Pascal Compiler is available for different processors Intel x86, Amd64/x86 64 (from 1.9.6), PowerPC (from 1.9.2), Sparc (from 1.9.6) and Motorola 680x0 (1.0.x only).
The following operating systems are supported Linux, FreeBSD, NetBSD, MacOSX/Darwin, MacOS classic, DOS, Win32, OS/2, BeOS, SunOS (Solaris), QNX and Classic Amiga.
Main features:
- Very clean language Pascal is a very nice language, your programs will be more readable and maintainable than for example in C, and lets even forget about C++. And you dont need to give up the power, the Pascal language is as powerful as you want it.
- No Makefiles Unlike most programming languages, Pascal does not need Makefiles. You can save huge amounts of time, the compiler just figures out itself which files need to be recompiled.
- Pascal compilers are Fast with a big F and Free Pascal is no exception. Yes, you no longer need to grow roots while compiling your programs, just hit the compile key and its done, even for large programs.
- Each unit has its own identifiers In Pascal you never need to worry about polluting the namespace, like in C where an identifier needs to be unique accross the entire program. No, in Pascal each unit gets its own namespace and thats very relaxed.
- Integrated development environment Free Pascal comes with an IDE which work on several platforms, in which you can write, compile and debug your programs. You will save huge amounts of time using the IDE, the best programming friend you have.
- Great integration with assembler Do you think pascal is for wimps who need to learn programming? WRONG! Its excellent for high tech programming and for the supreme nerds among you we have the integrated assemblers. You can easily mix assembler code and Pascal code, in the language you wish? Prefer Intel styled assembler? No problem, if its needed Free Pascal will convert it to ATT for you. Do you want to convert your program into a source file for Nasm? No problem, and all ATT assembler in your source files is automatically converted.
- Object oriented programming And if you do the serious programming, you are of course very interested in object oriented programming. Use the Turbo Pascal and Object Pascal ways of OOP according to your taste. The FCL and Free Vision and provide you with the powerful object libraries you need. For your database needs we support PostgreSQL, MySQL, Interbase and ODBC.
- Smartlinking Free Pascals smart linker leaves out any variable or code that you do not use. That makes small programs small with a big S, while they are still statically linked, avoiding DLL hell!
- Distribution independence (Linux) As a result of this, software compiled by the Linux version of Free Pascal runs on any Linux distribution, making it much, much, easier to make your software support multiple Linux distributions.
- Available for a lot of platforms on several architectures Free Pascal is available for more platforms than most other Pascal compilers and allows easy cross-compiling, just change the target in the IDE and compile! And there is work going on for even more platforms and processors.
- Compatible Have existing code? Free Pascal is more compatible with it than any other Pascal compiler. We are almost completely compatible with Turbo Pascal and quite well compatible with Delphi source code. If you have code in another language, like C or assembler, just use favorite compiler for it and call it from Free Pascal.
Version restrictions:
- For the intel 80x86 version at least a 386 processor is required, but a 486 is recommended. For the motorola 680x0 version, a 68020 or later processor is recommended. In all cases, a minimum of 8 Megabytes of RAM is recommended, but the compiler is reported to work with 4 Megabytes of RAM.

Undisposable Clients project provides easy-to-use API kits for using Undisposable.org in various programming languages.
Main features:
- Protects site owners biggest assets; userbase and emails
- Prevents userbase contamination by fake accounts
- As critical as email validity check
- Stops people registering your services with disposable email accounts like jetable.org, pookmail
- Detects public accounts (spread from sites like bugmenot.com) and bans them
- Working principle is similar to spam blacklists like spamhaus.org; power of masses
- Totally free, your donations are welcome
How to use it
Check if there is an API kit for your programming language, if there isnt, connect to our servers manually.
Add a few extra lines to your email validation function which is called from your member registration page. The following is an example in PHP language:
..
function checkEmail($email) {
include_once("undorg/php/rest/undisposable.inc.php"); // include the API kit
if(!undorg_isDisposableEmail($email)) { // check if disposable email
.. // old procedures remain here
} // add this line to close the conditional statement
}
..
?>
Thats all. Very simple...

MassCalculator is a Perl module that implements common mass computations in mass spectrometry.

SYNOPSIS

use InSilicoSpectro::InSilico::MassCalculator;
InSilicoSpectro::InSilico::MassCalculator::init(insilicodef.xml);

MassCalculator Perl library is intended to support common mass spectrometry-related computations that must be routinely performed by bioinformaticians dealing with mass spectrometry data.

To accommodate as many as possible user requirements, we decided to both support a classical procedural programming model and an object oriented model. Per se MassCalculator is not designed as an object oriented code but we provide a series of elementary classes for modeling proteins, peptides, enzymes, etc. which MassCalculator is compatible with. Moreover, the latter classes are rather simple and neutral in their design such that they should fit, after further derivations eventually, a large range of code design.

We decided not to use Perl object oriented programming to stay with relatively naive and simple code and to allow everybody to decide how to include it in its own project. Nonetheless, MassCalculator is able to deal with Perl objects we provide additionally to represent protein sequences, peptides, enzymes, mass lists, and fragmentation spectra, see their respective documentations.
MassCalculator is released under the LGPL license (see source code).

JDOInstruments is an embedded object oriented database programmed in java, it is also an implementation of Suns Java Data Objects (JDO) specification for the transparent persistence of Java objects.
Because of this, it doesnt need a JDBC driver or a relational database. JDOInstruments uses its own object store thus it allows storage and retrieval of persistent data with little work from you.
It is integrated with Netbeans IDE (via Plugin module) allowing developers to build pure object-oriented systems.
It is free and Our license is GNU LGPL providing the code and executables (JARs) free of charge. You are free to use JDOInstruments in your projects.
