JVM Garbage Collection and Optimizations

Image
Overview When troubleshooting systems for performance-related issues, memory optimizations are a place that needs a deep analysis of what each system stores in the memory, how long those are stored, and access patterns. This post is to keep a note on the background information and valuable points to note in such an effort, specific to Java-based implementations as a deep understanding of the JVM behaviors is very beneficial in the process.

Java language provides much convenience to the developers by taking care of the memory management to a great extent letting the focus be on the rest of the logic. Still having a good understanding of how Java does this underneath, rationalize several best practices we follow in Java implementations and help design the programs better and think seriously on some aspects that can later lead to memory leaks and system stability in the long run. Java Garbage Collector has a big role in this been responsible for freeing up memory by removing memory gar…

WSO2Con - 2011

WSO2Con - 2011, the event of the year!

I found it a great a pleasure to have a chance to attend this event, which is to be a huge event in middle-ware industry with participations from Google, IBM and eBay and a perfect pool for technology lovers. Only few lucky students will get the chance to be there at student rates. But the great news is still you can reserve your place for a very low price regrading the value of this three-day conference with two more days in tutorials. Try and see whether you can catch the early bird rates too.

Check out event agenda and the registration page for more information. Here is what Dr. Sanjiva Weerawarna CEO-WSO2 has to say about the event.






MIT-AITI Experience–Part 3 /Demo Day

Image
It was our dream day, it was the day we waited to show off the results of the intensive hard work we did in just 6 weeks and got the maximum of out of it. I will be sharing that experience with this post.

We have been finished developing our product to the level to do a live demo by that time and unfortunately with the nature of our product ‘ThenaHari’, we were unable to perform it inside a conference hall. Following were the problems we had and the solutions we found with the help of Samidh, Lisa and Micheal. Simulate an outside journey inside a hall – We developed a simulator that mimics the path of a passenger travelling in a bus route. This simulator was mainly developed by Manoj, one of mobiAssist co-founders, with the contribution of others. This also solved the problem of not having a way to access a the LBS(Location Based Service) of service provider to track passenger location which was great. Making the alert via fake call – As we still did not had access to a service provid…

MIT-AITI Experience–Part 2

I am writing after completing the whole course and becoming a director and a co-founder of the company mobiAssist, the creator of ‘ThenaHari’. I would like to begin the story from where I stopped at previous post. After having fun at the end of 2nd week with elevator pitch competition we had a week filled with technical stuff with the help and guidance Micheal. Parallel to that Samidh and Lisa introduced us to the marketing principles, entrepreneurship skills and presenting and lot more. Those rest 4 weeks became so intensive with work and of course lot of fun too. Below I will be describing few important events that took place during those 4 weeks. Our product page product page at MIT site can be found in the given link. A photo coverage total photo coverage on overall program can be found . Hackathon This was a really cool and challenging experience. We were given 24 hours to complete as much as we can in our products and the group which create the most progress was to win. Meanwhile Mic…
