Recently, I had to implement a machine learning algorithm called MLRules. I found the code on the author's webpage but there was a big problem. It was in Java using the WEKA environment. I had never worked in the Java before. Above that, I had another alien named 'weka'. Initially everything seemed out of the world. I tried different things, searched on google, read wiki after wiki but there doesn't seem to be a working solution of adding new classifiers in form of .jar files to run in weka. My search on google began with query 'adding jar files to weka'. I searched and searched till the query became 'cannot add jar file to weka'. I was nearly ending an unsuccessful pursuit of the 'WEKA' when one of the results came up from the 'google code' site about adding thier code to weka. The steps were well documented. I tried working it out and ALAS!!! it started working. It took a week's time just to do a simple thing. I ran the code and it ...

I was bugged to install Matlab 32-bit on my system that had a newly installed Ubuntu 64bit Linux. Matlab couldn't find the right JRE for the 64-bit architecture and ran only in command-prompt. After lot of wandering on the net, i found a simple solution the the problem. I had to manually set the JAVA path for matlab. For this i used the command : export MATLAB_JAVA='/usr/lib/jvm/ia32-java-6-sun-1.6.0.06/jre' After this i just ran the command to start matlab : matlab -glnx86 Remmber to put it in .bashrc to get it done every time you start matlab from bash.

Recently, I had lots of problem in joining or merging different pdfs. There are many licensed softwares available. On using them as shareware would work but almost all made the pages of thus generated pdfs really unusable by putting large remarks that you need to register. After lots of roaming around the web and googling, I found a very neat and simple solution to all my problems. This is the PDF Split and Merge or PDF-SAM as it is called. It is a project going on sourceforge.net. That means "ITS COMPLETELY FREE". And above all, we can access even the source code of the project. This doesn't seem that interesting but considering the power of open-source softwares, this may be very helpful. I don't think it needs any more explanation as it is very simple to use, say for merging: 1: Choose the tab "MERGE" 2: Add as many files as you want 3: Set the path. Be little careful here and give the whole path or it throws back an error. Or simply, just press browse an...
