Free charging software for linux

Valgrind is an award-winning suite of tools for debugging and profiling Linux programs. With the tools that come with Valgrind, you can automatically detect many memory management and threading bugs, avoiding hours of frustrating bug-hunting, making your programs more stable. You can also perform detailed profiling, to speed up and reduce memory use of your programs.
Valgrind distribution currently includes three tools: a memory error detectors, a cache (time) profiler and a heap (space) profiler.
Valgrind is Open Source / Free Software, and is freely available under the GNU General Public License.
Main features:
- Valgrind will save you hours of debugging time. With Valgrind tools you can automatically detect many memory management and threading bugs. This gives you confidence that your programs are free of many common bugs, some of which would take hours to find manually, or never be found at all. You can find and eliminate bugs before they become a problem.
- Valgrind can help you speed up your programs. With Valgrind tools you can also perform very detailed profiling to help speed up your programs.
- Valgrind is free. Free-as-in-speech: you can download it, read the source code, make modifications, and pass them on, all within the limits of the GNU GPL. And free-as-in-beer: we arent charging for it.
- Valgrind runs on x86/Linux, AMD64/Linux and PPC32/Linux, several of the most popular platforms in use. Valgrind works with all the major Linux distributions, including Red Hat, SuSE, Debian, Gentoo, Slackware, Mandrake, etc.
- Valgrind is easy to use. Valgrind uses dynamic binary translation, so you dont need to modify, recompile or relink your applications. Just prefix your command line with valgrind and everything works.
- Valgrind is not a toy. Valgrind is first and foremost a debugging and profiling system for large, complex programs. We have had feedback from users working on projects with up to 25 million lines of code. It has been used on projects of all sizes, from single-user personal projects, to projects with hundreds of programmers.
- Valgrind is suitable for any type of software. Valgrind has been used on almost every kind of software imaginable: desktop applications, libraries, databases, games, web browsers, network servers, distributed control systems, virtual reality frameworks, transaction servers, compilers, interpreters, virtual machines, telecom applications, embedded software, medical imaging, scientific programming, signal processing, video/audio programs, NASA Mars lander vision and rover navigation systems, business intelligence software, financial/banking software, operating system daemons, etc, etc. See a list of projects using Valgrind.
- Valgrind is widely used. Valgrind has been used by thousands of programmers across the world. We have received feedback from users in over 25 countries, including: Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Italy, The Netherlands, Norway, Poland, Portugal, Russia, Sweden, Switzerland, UK, Argentina, Brazil, Canada, USA, Australia, India, Japan, New Zealand, Singapore, South Africa and Israel.
- Valgrind works with programs written in any language. Because Valgrind works directly with program binaries, it works with programs written in any programming language, be they compiled, just-in-time compiled, or interpreted. The Valgrind tools are largely aimed at programs written in C and C++, because programs written in these languages tend to have the most bugs! But it can, for example, be used to debug and profile systems written in a mixture of languages. Valgrind has been used on programs written partly or entirely in C, C++, Java, Perl, Python, assembly code, Fortran, Ada, and many others.
- Valgrind debugs and profiles your entire program. Unlike tools that require a recompilation step, Valgrind gives you total debugging and profiling coverage of every instruction executed by your program, even within system libraries. You can even use Valgrind on programs for which you dont have the source code.
- Valgrind can be used with other tools. Valgrind can start GDB and attach it to your program at the point(s) where errors are detected, so that you can poke around and figure out what was going on at the time.
- Valgrind is extensible. Valgrind consists of the Valgrind core, which provides a synthetic software CPU, and Valgrind tools, which plug into the core, and instrument and analyse the running program. Anyone can write powerful new tools that add arbitrary instrumentation to programs. This is much easier than writing such tools from scratch. This makes Valgrind ideal for experimenting with new kinds of debuggers, profilers, and similar tools.
- Valgrind is actively maintained. The Valgrind developers are constantly working to fix bugs, improve Valgrind, and ensure it works as new Linux distributions and libraries come out. There are also mailing lists you can subscribe to, and contact if youre having problems.
- So whats the catch? The main one is that programs run significantly more slowly under Valgrind. Depending on which tool you use, the slowdown factor can range from 5--100. This slowdown is similar to that of similar debugging and profiling tools. But since you dont have to use Valgrind all the time, this usually isnt too much of a problem. The hours youll save debugging will more than make up for it.
Enhancements:
- 3.2.3 is almost identical to 3.2.2, but fixes a regression that unfortunately crept into 3.2.2. The regression causes an assertion failure in Valgrind when running certain obscure SSE code fragments on x86-linux and amd64-linux. Please do not use (or package) 3.2.2; instead use 3.2.3.

After decades of war one company, who had gained powerful supplying both sides with weaponary, steps forwards and crushes both warring factions in one swift movement.
Using far superior weaponary and AI craft, the company was completely unstoppable and now no one can stand in their way.
Thousands began to perish under the iron fist of the company. The people cried out for a saviour, for someone to light this dark hour... and someone did.

molsKetch is a molecular drawing tool.
molsKetch is a program for drawing molecular structures, in the spirit of Chemsketch and xdrawchem, for all platforms supported by Qt 4. As for now it supports drawing a basic carbon skeleton, adding hetero atoms and charge and different types of bonds. The resulting structure can be exported to all formats supported by the OpenBabel library and can also be exported as SVG or bitmap. For a full overview of the features see below.
This application is the result of a project for school (as well as my first Qt application). The goal of the project was to design a proof-of-concept tool for drawing molecular structures quick and easily, without sacrificing the quality of the resulting images. There is still much room for improvement, but it should be quite useful already. So youre free to give it a try.
Main features:
- creating regular and consistent bonds easily with tools as a dynamic grid and magnetic atoms
- open, save and import in all formats supported by the OpenBabel(tm) library
- export to Scalable Vector Graphics (SVG) and a number of common used bitmap formats
- print and export your document to PDF
- realign atoms automatically
- intelligent addition/removal of hydrogen atoms
- real time information about the molecule, like charge and weight
- built-in library for quick access to regularly used molecules and functional groups

KThinkBat is a laptop battery monitor for the KDE-Kicker. KThinkBat is inspired by the "Battery Maximizer" includes with IBM ThinkPads (now Levono).
Yes, I know, there is allready a standard battery monitor KDE-Application, but it is simply too small to realize the real battery charge at first blush.
Installation:
The simplest way to compile this package is:
1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system. If youre using `csh on an old version of System V, you might need to type `sh ./configure instead to prevent `csh from trying to execute `configure itself.
Running `configure takes a while. While running, it prints some messages telling which features it is checking for.
2. Type `make to compile the package.
3. Type `make install to install the programs and any data files and documentation.
4. You can remove the program binaries and object files from the source code directory by typing `make clean.
Enhancements:
- Added Czech translation send by Martin Samek
- Refactored complete internal battery handling
- Introduced new abstract base class for Bat Info
- Added new Bat Info Sum class
- Fixed bug with wrong calculation remaining time when using two batteries
- Translation updates: Bulgarian (by Aleksandar Tsankov), German, Slovak (by Jozef Riha), Spanish (Luis Sobalvarro)
- Show current power consuption as current charge rate if charging
- More intelligent remaining time calculation in battery summary mode (if only one battery present, use the more accurate value from this battery instead of generic recalculation)
- Added COPYING.LIB (LGPL) and COPYING.DOC (GNU FDL) as some files are released under these licenses (thanks to Harald Sitter from Kubuntu team)
