Graph Visualization Program

Most teachers and students would like to put their understanding or studies in a graphic mode. It seems to be much easier to remember and/or  to study. We are today presenting another free and open source program for graphics - it's called graphviz.

It has important applications in networking, bio-informatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains.

The Graphviz layout programs take descriptions of graphs in a simple text language, and make diagrams in useful formats, such as images and SVG for web pages; PDF or Postscript for inclusion in other documents; or display in an interactive graph browser.

GraphViz lets you use simple text or GXL (a variant of XML) to describe charts, and then it does the drawing work for you. See the Gallery for examples of the types of graphics it can create. Operating Systems: Windows, Linux, OS X.

If you need to download it go here. Documentation is found here. Any discussions are carried out in the forum. The Gallery will show you work which could be done using graphviz.

Double Commander

The saying in English goes…..finding a needle in a haystack. When was the last time that one looked for a file (desperately), and couldn’t find it? By time, one adds so many files that it becomes a nightmare to look for it especially before an important exam or presentation!

Today we’re presenting Double Commander. It is available for Linux, Mac, Windows and FreeBSD. It opens up and shows two panels of one’s hard disk. So one can easily find the missing file or else transfer the file from one part of the hard disk to another (or usb).

Besides this, one can use it to split files, pack files, compare or change attributes or permissions.

Its home page is here. If one wants to download it, then click here. For any problems, questions etc...click on the forum.

The computer reads the text for you!

Some students like multitasking. They would like to study as they do other duties like for example cleaning their room, cooking etc…..Other students have impairments with vision.

What’s the solution? Well a program can transform words into sounds where the computer reads the contents of a page and transforms it into speaking...as if a person is reading the text!! Some students would prefer to study in this manner, because it helps them assimilate better the educational content. It helps them to face the lonely days of studying especially if they are living on their own.

Our solution works in Linux, Windows, Solaris, Android and Mac. It is called espeak. It can be downloaded from here. If one needs documentation, it is here. The forum is quite helpful for newbies.
