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...

Most people who know me personally know that I'm an Open Source enthusiast. And they probably know that I'm more of a SysAdmin than a developer. Well, thats quite true. Eventhough I enjoyed programming, my main interest was always System (especially Linux) administration. However in the last 6-8 months aor so I've started getting more and more into Open Source development. A major breakthrough for me was getting selected for Google Summer of Code 2007, to participate in Nmap! (Nmap is much like a grail among SysAdmins :) Unfortunately my persoanl circumstances didn't allow me to finish the work with them. Family matters and other things piled up and I have to give up. Nmap people has been very supportive though and the same was true about the Google people. So after some weeks here I was trying to look more into Nmap, Metasploit and other things. Then I realized that I could give sometime to this Ruby thing which I heard was on Rails or something. Here I am now, after a...
