Linux 20-years celebration video in tamil

Hi friends,

At 1991, Linus Torvalds, released his Kernel as open source. After that, the Linux Revolution happened.

To celebrate the 20 years of Linux, The Linux Foundation, is doing various activities.
Explore it here. http://www.linuxfoundation.org/20th
It released an animation video.

My Brother T.Shrinivasan wanted to translate the video in tamil. So he asked his friend to transcribe the audio as English text. He then also asked me to  convert the English text into Tamil text.

Here the original English version video:


Here the tamil version of the above video:

Installing Apache Solr 1.4.1 on ubuntu 10.04

Hi friends,

Let’s see How to install this on ubuntu 10.04

Installing Tomcat 6 in Ubuntu 10.04 and Libmysql-java:

$ sudo apt-get update && apt-get upgrade
$ sudo apt-get install tomcat6 tomcat6-admin tomcat6-common tomcat6-user tomcat6-docs tomcat6-examples

$ sudo apt-get install libmysql-java

Download apache-solr-1.4.1.tgz from http://lucene.apache.org/solr/ and extract it:
$ cd <to path of extracted solr>
$ sudo cp apache-solr-1.4.1/dist/apache-solr-1.4.1.war /usr/share/tomcat6/webapps/solr.war
$ sudo cp -R apache-solr-1.4.1/example/solr/ /usr/share/tomcat6/solr/

note : we copy solr folder into /usr/share/tomcat6 and it will pointed as solr home in next step.

Create new Solr configuration in Tomcat6:

$ sudo vim /etc/tomcat6/Catalina/localhost/solr.xml

Paste this into file :

<Context docBase="/usr/share/tomcat6/webapps/solr.war" debug="0" privileged="true" allowLinking="true" crossContext="true">
<Environment name="solr/home" type="java.lang.String" value="/usr/share/tomcat6/solr" override="true" />
Enable MultipleCore in Solr 1.4.1:

$ sudo cp apache-solr-1.4.1/example/multicore/solr.xml /usr/share/tomcat6/solr/solr.xml
$ sudo cp -R apache-solr-1.4.1/example/multicore/core0 /usr/share/tomcat6/solr/
$ sudo cp -R apache-solr-1.4.1/example/multicore/core1 /usr/share/tomcat6/solr/
$ sudo mkdir /usr/share/tomcat6/solr/core0/data
$ sudo mkdir /usr/share/tomcat6/solr/core1/data
$ sudo chown -R tomcat6:tomcat6 /usr/share/tomcat6/solr/core0/data/
$ sudo chown -R tomcat6:tomcat6 /usr/share/tomcat6/solr/core1/data/
Finally, restart your Tomcat and check it out!

$ sudo service tomcat6 restart

Go to http://localhost:8080/solr/


Now, i got the screen like this,

This slideshow requires JavaScript.

I don’t know how to use this and  how to configure.xml file.  B’coz when i search something, i didn’t get anything, i got some errors ly  😦

Apache solr ==> search platform

Hi friends,

Today my room-mate Mr.Thanigai told about “apche solr” and he told try to install “Apache Solr” on his ubuntu 10.04. Then, i searched abt it in google. Finally i got a small idea abt “solr”.

[From solr main page]

Solr is the popular, blazing fast open source enterprise search platform from the Apache Lucene project. Its major features include powerful full-text search, hit highlighting, faceted search, dynamic clustering, database integration, and rich document (e.g., Word, PDF) handling. Solr is highly scalable, providing distributed search and index replication, and it powers the search and navigation features of many of the world’s largest internet sites.

Solr is written in Java and runs as a standalone full-text search server within a servlet container such as Tomcat. Solr uses the Lucene Java search library at its core for full-text indexing and search, and has REST-like HTTP/XML and JSON APIs that make it easy to use from virtually any programming language. Solr’s powerful external configuration allows it to be tailored to almost any type of application without Java coding, and it has an extensive plugin architecture when more advanced customization is required.


  • Uses the Lucene library for full-text search
  • Faceted navigation
  • Hit highlighting
  • Query language supports structured as well as textual search
  • JSON, XML, PHP, Ruby, Python, XSLT, Velocity and custom Java binary output formats over HTTP
  • HTML administration interface
  • Replication to other Solr servers – enables scaling QPS
  • Distributed Search through Sharding – enables scaling content volume
  • Search results clustering based on Carrot2
  • Extensible through plugins
  • Pluggable relevance – boost through formula
  • Caching
  • Embeddable in a Java Application.
