As most you have already heard, Sir Arthur C. Clarke , the British/Sri Lankan writer and visionary passed way this morning in Apollo Hospital. Clarke who was a house hold name in Sri Lanka was living in the country from 1956. It is said that the souther sea is what brought Clarke here. It is a know fact that he really liked the places like Unawatuna, Roomassala, etc. Clarke was a worldwide known person for his famous work like the Odyssey series (2001, 2010, 2061, 3001) and Rendezvous with Rama, Fountains of Paradise, The Deep Range, etc. and also for inspirational visionary work. For me, "The Deep Range" is the favourite, not at any rate because of the Sri Lankan connection in the book, but because of the illustration of Ocean and creatures it creates. I'll always keep re-reading it to experience that wonderful feeling of being in the Ocean. This is also the book where Clarke points that we could look into the sea before going to walk among the stars. Sir Clarkes passin...

Summer is going to be upon us very soon and it looks certainly awesome. As usual Google is brightening it up. Google Summer of Code or more lovingly called GSoC or SoC has been announced for the fourth consecutive run! (Meanwhile let's hope lives would be better for the people affected by the forces of nature in past few days.) Google Summer of Code is a student program where university (BSc, MSc, etc.) students can work for an Open Source software project for 3 months under Google sponsorship. I was one of the lucky students last year (but had to resign due to a couple of domestic bereavements). This years program is announced and I hope at least a few excellent coders will be interested in this news. Please convey this news to relevant students, while I check out any interesting project for me. :) And remember last year about a 20 add students were selected from Sri Lanka. So don't think you don't have any chance. You just have to be enthusiastic, skilled (in coding) and...

Again, I'm not switching to Java. :) For clarity, I'm helping one of my online buddies to setup and use Ruby even as I write this. This work was something I had to do for a Rails project which used JSPs and stuff with a MySQL database over JDBC. The application setup was quite interesting calling JSPs to work with a Rails webapp. Actually the following things are found on the Internet. I cannot remember all the sources I looked at, but one was the MySQLs own documentation and Apache Tomcat documentations. So if this works (which in my case did), credit should not be mine. :) Here's the setup. GNU/Linux (in my case CentOS 5, although should work with any Linux distro) Apache Tomcat (5.5.25, should work with Tomcat 5.5 range) Sun JDK (1.6.0_04) MySQL (5.0.22) MySQL Connector/J (5.1) 1. I assume that Java is setup ( See my previous post for more details on setting up Java manually), and your MySQL is running on the same host on port 3306. Please replace your actual settings i...

I'm not switching to Java. :) But this particular thing is something I've answered several times. So instead of repeating it every time, I'll put the details here and point others here. Installing Sun's Java (JDK and JRE) manually, without using something like yum, apr-get, urpm, etc. seems to be something many desktop (or whatever) Linux users want. For example they want to run certain applications like NetBeans, FrostWire, etc. which require a JRE to be available. This tutorial is going to take you through the steps you need to setup a working JRE/JDK on a Linux system. You may as well take this idea and tune it for your non-Linux environments like Solaris, *BSD. Note: This howto assumes you have 'sudo' configured for you. If you don't have 'sudo' configured, you'll have to either use 'su' or login as root to use the commands I have provided with 'sudo' at the beginning. Please replace file names and paths in this howto with you...
