Free diagram editor software for linux

Ghost Diagrams is a project that takes sets of tiles and tries to find patterns into which they may be formed. The patterns it finds when given randomly chosen tiles are often surprising.

It turns out that tiling patterns are a form of computation of equal power to Turing machines, lambda calculus, and cellular automata. For example, here is a tileset implementing "Rule 110", a cellular automaton known to be capable of universal computation.

Considerations similar to the halting problem and Godels theorem apply. There is no upper limit to their capacity to surprise us. Furthermore, tiles have an intuitive quality that other forms of computation lack. You can see how they fit together.

An organism is more than the sum of its organs. When the organs are fitted together, the organism becomes something more. This surprising something more we call "spirit" or "ghost". Ghost Diagrams finds the ghosts implicit in simple sets of tiles.

Hardware Monitor is a multi-purpose, beautiful system-monitoring applet.
The Hardware Monitor applet is an applet for the GNOME panel which tries to be a beautiful all-around solution to system monitoring. It also strives to be user-friendly and generally nice and sensible, integrating pleasantly with the rest of your GNOME desktop.
Includes different viewers, including a flame effect, allows multiple devices to be monitored in the samme applet, uses smooth updating, polished graphs, clean HIG-compliant interface.
Main features:
- A graphical view where each monitor is represented by a (time, measurement) colored curve
- A bar-plot view with a horizontal bar per monitor
- A column view with a column (time, measurement) diagram for each monitor
- A textual view which simply lists the monitors and the currently measured values
- A flame view which produces spiffy flames, the sizes of which are determined by the values of the monitored device
And the applet supports monitoring the following hardware characteristics:
- CPU usage (all CPUs, or one at the time) - niced background processes such as SETI@home are automatically ignored
- Memory usage - cache and buffers are automatically ignored
- Swap usage
- Load average
- Disk usage (or disk space free)
- Network throughput (Ethernet, wireless, modem, serial link), either incoming or outgoing or both
- Temperatures from internal sensors (e.g. system board and CPU temperatures)
- Fan speeds from internal sensors

SDE for NetBeans is a UML modeling environment tightly integrated with NetBeans.
It lets you draw all types of UML diagrams (use case diagram, class diagram, sequence diagram, activity diagram, etc.) in NetBeans, reverse source code (Java, C++, XML, XML Schema, CORBA IDL, etc.) to UML models, and generate Java source from UML diagrams.
SDE for NetBeans Community Edition features a Rational Rose importer, an XMI importer, HTML/PDF documentation generators, and plug-in and template support.
Enhancements:
- Branch and tag capability was added to the VP Teamwork Server with Subversion and CVS repository integration.
- This allows different modeling projects to be run in parallel while keeping the release quality project stable in the trunk.
- A user interface designer was introduced for creating screen mock-ups in the early stages of a software development project.
- Usability of the sequence diagram was increased.
- There were also a number of enhancements for various other features.

Autodia::Handler::Torque Perl module contains an AutoDia handler for Torque xml database schema.

This provides Autodia with the ability to read Torque Database Schema files, allowing you to convert them via the Diagram Export methods to images (using GraphViz and VCG) or html/xml using custom templates or to Dia.

SYNOPSIS

use Autodia::Handler::Torque;

my $handler = Autodia::Handler::dia->New(%Config);

$handler->Parse(filename); # where filename includes full or relative path.

Description

The Torque handler will parse the xml file using XML::Simple and populating the diagram object with class, superclass, and relationships representing tables and relationships.

The Torque handler is registered in the Autodia.pm module, which contains a hash of language names and the name of their respective language.

An example Torque database schema is shown here - its actually a rather nice format apart from the Java studlyCaps..

DiaDBDesigner is a standalone module for constructing databases with the help of the diagram creation program Dia.

In an easy to use environment, with DiaDBDesigner you can join multiple diagrams together to form one model of interconnected tables.

Medoosa is an application which creates UML class diagrams from C++ sources.

Corrections can be made interactively in a diagram editor (Dia) and are fed back into the source as Javadoc-style comments.

At this time, the layout must still be done by hand. Some code is already present to produce the layout with Graphviz.

Dia is designed to be much like the commercial Windows program Visio. It can be used to draw many different kinds of diagrams.

Dia project currently has special objects to help draw entity relationship diagrams, UML diagrams, network diagrams, flowcharts, and simple circuits. It is also possible to add support for new shapes by writing simple XML files, using a subset of SVG to draw the shape.

It can load and save diagrams to a custom XML format (gzipped by default, to save space), can export diagrams to EPS or SVG formats and can print diagrams (including ones that span multiple pages).

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.
