South Talpatti lost for good

The disputed South Talpatti is no more :-). We could never take possession of it. Thanks to nature for taking caring of it. However, the news is not funny at all. It reminded me of the bleak future of Bangladesh in the face of global warming. It is predicted that 18 percent of our coastal area will be submerged and 20 million people will be displaced. Are our political parties aware of these issues? Or are they still busy figuring out who declared the independence?

RanksTel caught for illegal VoIP

RanksTel is found guilty of doing illegal VoIP business. I thought it was already a profitable organization with its land phone business. What led them to this illegal venture? Is it the greed they could not avoid? It is good to see that BTRC is active again catching the illegal VoIP operations. Big names are also coming up. I thought their activity has ended as soon as the elected government came to power. I am eager to see what proof BNP, the opposition party, provides to support their claim of Mr. Sajib Wazed Joy being involved in this business. It will be interesting to see what government does if BNP can provide some concrete evidences.

Getting openRDF Sesame 2.3.1 installation with Tomcat 6 to work

After deploying the war files: openrdf-sesame.war and openrdf-workbench.war by Tomcat's web-admin interface, I encountered the following problem while trying to access http://localhost:8080/openrdf-sesame/: access denied (java.util.PropertyPermission info.aduna.platform.appdata.basedir read)

I found a discussion about it here. Eventually I solved the problem in the following way:

1. Create and assign the home directory "/home/tomcat6" to tomcat6 user.
2. Create the directory "/home/tomcat6/.aduna".
3. Add the property "-Dinfo.aduna.platform.appdata.basedir=/home/tomcat6/.aduna/" in JAVA_OPTS in the /etc/default/tomcat6 file.
4. Restart Tomcat.

But this did not solve the problem. Then I had to turn off the security entirely which I am sure is not the recommended way. Here is what I did:

1. Set TOMCAT6_SECURITY=no in /etc/default/tomcat6 file.
2. Restart Tomcat.

Problem solved! But in an inelegant way. Does anyone have a better solution?

N.B.: lucene-2.9.2 must be in the classpath in order to get BigOWLIM-3.2.6 working properly.
