Free aids software for linux

Graidle (Graph aid), is a project that is proposed to create an application web for the realization of graph; it comes divided in four parts:
Graidle Fx proposed like didactic instrument for the visualization of diagrams of function to one variable;
Graidle SQL Friendly assists the creation of a graph starting from one query;
Graidle FrontEnd supplies to the user a graph personalized second every own requirement;
Graidle Class is the class that comes supplied for the development;
The realization of the site is apt to the demonstration of the operation of the same application, that it can be more complete visualizing sources releasable liberations in the appropriate Download section. We will have therefore one dedicated section to every part of the plan: In Function the customer will insert the number of functions to visualize, the interval and the quality of the curve and will come created a diagram to the flight; With the FronEnd they will be able to be inserted until to nine series give to you, choosing of the type, the name, the options like the colors, the title it, maximum and minimal, the lines grid etc... the customer will be able to save the just graphical one and to insert it in situated presentations or web; From SQL is a pure demonstrative and educational section, that it concurs to create given diagram of one query SQL; between the multiple usefullnesses there is that one of being able to visualize in realtime the graph of some give you present in database without or that one of being able to enclose to the tables of resultset a diagram that can clarify the visualization of gives to you; the handbook for who is available also wanted to externally use the class to this situated one;
The Graidle project is realized in PHP with the aid of GD2 library.

PyKanjiCard is a flash card program to aid learning japanese written words, in hiragana, katakana and kanji.
You can select words composed only by characters you already known. PyKanjiCard project is written in Python, using Pygtk.
Enhancements:
- A new restricted mode that loads only entries containing either Hiragana or Katakana and at least one character from known_chars was added.
- It can be accessed using the -r or --restrict optoin.
- A search bar was added.

pyhada ([py]thon [h]ttp [a]utosurfer [d]ock[a]pp), checks selected webpages periodically, for updates, and displays the updates in the dockapp.

What:

Pywmgeneral is a python module that will help you develope WindowMaker dockapps in python. It is mostly a wrapper around the functions from the popular wmgeneral.c, but some new functions are added too.

It also contains the Python written module pywmhelpers.py which contains functions to aid the development of wm dockapps. This module contains python functions that wrap up the functions which the extension module provides.

They ease up argument passing and give nicer return values. Some additional functions, like help for handling a simple configuration file is also available. This module is better documented than the pywmgeneral.

It is adviced to only use pywmhelpers and not touch the pywmgeneral module directly at all. For information about how to use the module, see the documentation in pywmhelpers.py. It is also possible to import it in the interactive interpreter and issue help(pywmhelpers).

QCad is an application for computer aided drafting in two dimensions. With QCad you can create technical drawings such as plans for buildings, interiors or mechanical parts. QCad works under Linux, Unix Systems, Mac OS X and Windows. The source code of QCad is released under the GPL (Open Source).
QCad was designed with modularity, extensibility and portability in mind. But what people notice most often about QCad is its intuitive user interface. QCad is a simple 2D CAD system for everyone. You dont need any CAD experience to get started with QCad immediately.
Main features:
- Various modes for creating lines, arcs, circles, ellipses, parallels, angle bisectors, ...
- DXF Format (DXF 2004, R12)
- Texts in many different CAD fonts
- Dimensioning of distances, angles, diameters, tolerances, ...
- Hatches and solid fills
- Splines
- Full support of Layers and Blocks (Inserts)
- Powerful selection and modification tools (move, rotate, mirror, trim, stretch, ...)
- Snapping to objects (endpoints, centers, intersections, ...)
- Console for co-ordinate positioning and launching commands
- Multiple undo / redo levels
- Support for various units including metric, imperial, degrees, grad, rad, ...
- Import and Export of Bitmaps (JPEG, PNG, ...)
- Creation of PS files which can be easily converted to PDF
- Translations of the user interface: Czech, Danish, Dutch, English, Estonian, French, German, Greek, Hungarian, Italian, Polish, Russian, Slovak, Spanish, Turkish
- Scripting interface
Enhancements:
- This update features improved DXF compatibility, improved support for ellipses, and some fixes for OS X.

GraphViz is a Perl interface to the GraphViz graphing tool.

SYNOPSIS

use GraphViz;

my $g = GraphViz->new();

$g->add_node(London);
$g->add_node(Paris, label => City ofnlurve);
$g->add_node(New York);

$g->add_edge(London => Paris);
$g->add_edge(London => New York, label => Far);
$g->add_edge(Paris => London);

print $g->as_png;

This module provides an interface to layout and image generation of directed and undirected graphs in a variety of formats (PostScript, PNG, etc.) using the "dot", "neato", "twopi", "circo" and "fdp" programs from the GraphViz project (http://www.graphviz.org/ or http://www.research.att.com/sw/tools/graphviz/).

What is a graph?

A (undirected) graph is a collection of nodes linked together with edges.
A directed graph is the same as a graph, but the edges have a direction.

What is GraphViz?

This module is an interface to the GraphViz toolset (http://www.graphviz.org/). The GraphViz tools provide automatic graph layout and drawing. This module simplifies the creation of graphs and hides some of the complexity of the GraphViz module.

Laying out graphs in an aesthetically-pleasing way is a hard problem - there may be multiple ways to lay out the same graph, each with their own quirks. GraphViz luckily takes part of this hard problem and does a pretty good job in a couple of seconds for most graphs.

Why should I use this module?

Observation aids comprehension. That is a fancy way of expressing that popular faux-Chinese proverb: "a picture is worth a thousand words".
Text is not always the best way to represent anything and everything to do with a computer programs. Pictures and images are easier to assimilate than text. The ability to show a particular thing graphically can aid a great deal in comprehending what that thing really represents.

Diagrams are computationally efficient, because information can be indexed by location; they group related information in the same area. They also allow relations to be expressed between elements without labeling the elements.
A friend of mine used this to his advantage when trying to remember important dates in computer history. Instead of sitting down and trying to remember everything, he printed over a hundred posters (each with a date and event) and plastered these throughout his house. His spatial memory is still so good that asked last week (more than a year since the experiment) when Lisp was invented, he replied that it was upstairs, around the corner from the toilet, so must have been around 1958.

Spreadsheets are also a wonderfully simple graphical representation of computational models.

Klaid - K Learning Aid pops up kvtml file items on the desktop. Use KWordQuiz or FlashKard to produce kvtml files and load them into Klaid. It will grab all complete n x m related items (e.g. "Question" and "Answer", or "Word A" and "Word B") and displays them periodically as PopUps on the desktop. It is like someone is sitting behind you making sure you know all the terms for your next exam or test while surfing the web, coding, or whatever.
Intsllation:
Extract the archive, run "make -f Makefile.cvs && ./configure --prefix=PATH" first. Insert your KDE base installation dir for PATH. In Debian sid and Kubuntu that would be "/usr".
Then compile by typing "make". You may then install the program (as root) via checkinstall or "make install".
Enhancements:
- Version 0.7.6 beta
- Added dutch translation (thanks to Pieter Pareit), added slovenian translation (thanks to Jaka Kranjc), small bugfixes, source should now compile smoothly again

HelPass project aids users in creating and memorizing new passwords.

Warning:The install script is in a rough state.
