Free ultra small powerful gas engines software for linux

Simply Powerful ToolKit in short SPTK is a powerful widget toolkit based on the Fast and Light ToolKit (FLTK).
The goal of this library is to create the easy-to-use, compact and effective library of controls to extend the abilities of FLTK library.
It is geared for business-style application development with database support (ODBC). All the widgets support database connectivity. A special CDialog class makes editing database records very easy. Every widget can be connected to the field, and CDialog can be connected to the database table.
Most of the controls are database-bound. If you place them on the CDialog-derived window they can load and save information from/to database.
This is the first release version of my controls(widgets) library that was designed to work with FLTK. Im using it for about a year in the production project.
Enhancements:
- Fixed a bug in CField::asString() that cause returning an empty string for some non-empty fields.
- Added couple of small fixes for better error hanling in CRegistry.

Imager::Engines is a Perl module for programmable transformation operations.

SYNOPSIS

use Imager;

my %opts;
my @imgs;
my $img;
...

my $newimg = $img->transform(
xexpr=>x,
yexpr=>y+10*sin((x+y)/10))
or die $img->errstr;

my $newimg = Imager::transform2(%opts, @imgs)
or die "transform2 failed: $Imager::ERRSTR";

my $newimg = $img->matrix_transform(
matrix=>[ -1, 0, $img->getwidth-1,
0, 1, 0,
0, 0, 1 ]);

transform

The transform() function can be used to generate spatial warps and rotations and such effects. It only operates on a single image and its only function is to displace pixels.

It can be given the operations in postfix notation or the module Affix::Infix2Postfix can be used to generate postfix code from infix code. Look in the test case t/t55trans.t for an example.
transform() needs expressions (or opcodes) that determine the source pixel for each target pixel. Source expressions are infix expressions using any of the +, -, *, / or ** binary operators, the - unary operator, ( and ) for grouping and the sin() and cos() functions. The target pixel is input as the variables x and y.

You specify the x and y expressions as xexpr and yexpr respectively. You can also specify opcodes directly, but thats magic deep enough that you can look at the source code.

The Irrlicht Engine is an open source high performance realtime 3D engine written and usable in C++ and also available for .NET languages.
Irrlicht Engine is completely cross-platform, using D3D, OpenGL and its own software renderer, and has all of the state-of-the-art features which can be found in commercial 3d engines.
Weve got a huge active community, and there are lots of projects in development that use the engine.
You can find enhancements for Irrlicht all over the web, like alternative terrain renderers, portal renderers, exporters, world layers, tutorials, editors, language bindings for java, perl, ruby, basic, python, lua, and so on. And best of all: Its completely free.
Main features:
- High performance realtime 3D rendering using Direct3D and OpenGL [more]
- Platform independent. Runs on Windows95, 98, NT, 2000, XP and Linux.[more]
- Huge built-in and extensible material library with vertex and pixel shader support [more].
- Seamless indoor and outdoor mixing through highly customizeable scene mangagment. [more]
- Character animation system with skeletal and morph target animation. [more]
- Particle effects, billboards, light maps, environment mapping, stencil buffer shadows, and lots of other special effects. [more]
- .NET language binding which makes the engine available to all .NET languages like C#, VisualBasic, and Delphi.NET.
- Platform and driver independent fast software renderer included. It features z-buffer, gouraud shading, alpha-blending and transparency, fast 2D drawing.
- Powerful, customizeable and easy to use 2D GUI System with Buttons, Lists, Edit boxes, ..
- 2D drawing functions like alpha blending, color key based blitting, font drawing and mixing 3D with 2D graphics.
- Clean, easy to understand and well documentated API with lots of examples and tutorials.
- Written in pure C++ and totally object orientated.
- Direct import of common mesh file formats: Maya (.obj), 3DStudio (.3ds), COLLADA (.dae), DeleD (.dmf), Milkshape (.ms3d), Quake 3 levels (.bsp), Quake2 models (.md2), Microsoft DirectX (.X)... [more]
- Direct import of Textures: Windows Bitmap (.bmp), Portable Network Graphics (.png), Adobe Photoshop (.psd), JPEG File Interchange Format (.jpg), Truevision Targa (.tga), ZSoft Painbrush (.pcx)... [more]
- Fast and easy collision detection and response.
- Optimized fast 3D math and container template libraries.
- Directly reading from (compressed) archives. (.zip)
- Integrated fast XML parser.
- Unicode support for easy localisation.
- Works with Microsofts VisualStudio6.0?, VisualStudio.NET 7.0-8.0?, Metrowerks Codewarrior, and Bloodshed Dev-C++ with g++3.2-4.0.
- The engine is open source and totally free. You can debug it, fix bugs and even change things you do not like. And you do not have to publish your changes: The engine is licensed under the zlib licence, not the GPL or the LGPL.

Small Arms Ballistics is, as the name says, a ballistics calculator for small arms fire. It is a terminal application written using curses.
Small Arms Ballistics is derived from smallball, which was written by Ole-Hj. Kristensen. I have pretty much rewritten the entire program, but smallball got me started. All major
trajectory calculations have been implemented, and a variety of bullet drag models are available.
The program needs a color capable terminal, otherwise it wont run.
Enhancements:
- distribution didnt include saballistics.lsm.in

Damn Small Linux Not is built on Damn Small Linux technology. Damn Small Linux Not is also small, bigger than DSL but smaller than most. Damn Small Linux Not provides a reliable, and compact array of applications based mostly on the GTK2 libraries.
DSL-N is not an evolution of DSL, it is not intended as progress over the philosophy of DSL, but is intended for a different user, or the same user under different circumstances.
Main features:
- it is small
- it has software which is feature full
- it takes advantage of redundant lib dependencies and suits to pack features into a tight distribution
- DSL-N has a modern kernel and does not squeeze out critical modules that would limit compatibility
Like DSL, DSL-n can:
- Boot from from a CD as a live Linux distribution (LiveCD)
- Boot from a USB pen drive
- Boot from within a host operating system (thats right, it can run *inside* Windows)
- Run very nicely from an IDE Compact Flash drive via a method we call "frugal install"
- Transform into a Debian OS with a traditional hard drive install
- Run fully in RAM
- Modularly grow -- DSL-N is highly extendable without the need to customize
- The applications in DSL-N were chosen because they are functional, usable, and relatively compact. Unlike DSL, DSL-N has GTK2 applications, that means DSL-N will need more ram and CPU cycles than DSL. To have a pleasant experience, we recommend at least 64MBs and 300MHz.
DSL-N, unlike DSL, does not have a hard size cap, but it is being developed by the DSL team, and we hate bloat! So, dont expect DSL-N to get too big.
Why are you making this offshoot of DSL when DSL is so successful? Because a 50MB, GTK2 based distribution, with a 2.6.x kernel and excellent hardware detection/support is a contradiction in terms. DSL-N represents our best effort to stay compact while providing for the needs of those who want the Bling Bling such as SATA support, Gnumeric, Abiword, gMplayer.
Enhancements:
- Added "noprompt noeject" to default boot options for frugal installs.
- Fixed madwifi wireless.
- Fixed chpasswd vs passwd. "secure" boot option now works correctly.
- Added gnu-utils into the base iso.
- Fixed USB2 not loading bug
- Improved mydsl=hdxy when specified to not also search this makes it consistent with restore boot option.
- Enhanced exitcheck to prompt warning if no backup device is selected when requested to save special settings.
- Fixed multi user hard drive install bug.
- Added murgaLua Lua/Fltk development toolkit.
