Geo-visualisation, the FOSS way

 Posted on September 5, 2008  |  Santhosh Thottingal

My friend Jaisen Nedumpala has been developing a Geo-visualisation system for Cheruvannoor Grama Panchayath(Page in ml_IN) of Kerala. The system, developed using FOSS tools is available here “Development of effective geo-visualisation based decision support system (DSS) involved primarily data compilation from collateral sources, setting up appropriate hardware configuration, design of database and design of a spatial DSS. ” Jaisen used softwares like GRASS, UMN MapServer and ka-Map. He has written a detailed documentation(English) on how he developed this and what are all the tools used. [Read More]

UTF8Decoder

 Posted on September 1, 2008  |  Santhosh Thottingal

zabeehkhan was trying to code a Pashto (ps_AF) module for dhvani. And he told me that “it is not saying anything” :). So I took the code and found the problem. Dhvani has a UTF-8 decoder and UTF-16 converter. It was written by Dr. Ramesh Hariharan and was tested only with the unicode range of the languages in India. It was buggy for most of the other languages and there by the language detection logic and text parsing logic was failing. [Read More]

Dhvani Now Speaks Marathi

 Posted on June 25, 2008  |  Santhosh Thottingal

Thanks to Rahul Bhalerao , he wrote the Marathi module for dhvani– The Indian Language Text to speech System. Dhvani can speak 10 Indian languages now: Bengali, Gujarati, Hindi, Kannada, Malayalam, Marathi, Oriya, Panjabi, Tamil, and Telugu. Rahul also gave some patches for hindi module and for some other bugs. The code is available in CVS. The automatic language detection algorithm will not work for Marathi since it uses the devanagari script and I have assigned the unicode range used for language detection to Hindi. [Read More]

Canonical Equivalence in Unicode: Some notes

 Posted on June 3, 2008  |  Santhosh Thottingal

A process (or function) respects canonical equivalence when canonical-equivalent inputs always produce canonical-equivalent outputs. For a function that transforms one string into another, this may also be called preserving canonical equivalence. There are a number of important aspects to this concept: [Read More]

10 GB /var/log/messages file

 Posted on May 28, 2008  |  Santhosh Thottingal

Again fedora! 🙂 After the installation of linux kernel and linux operating system, I installed some libraries, some small applications that I usually use… I have a partition for Fedora 9 with 14 GB size. After installing all those softwares, when I rebooted the system today, the gdm was not starting. GDM kept on restarting and I could not take a user session by pressing ALT + CTRL + F1. hmm… So added single at the kernel argument in the grub, and got the shell. [Read More]
