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…

GSoC2012 with Apache Wookie

Today I got the news of the proposal I submitted to GSoC2012, is accepted. I consider it a great achievement and so excited to make the project a success. With the nature of the program it is no wonder anyone get excited about it. Firstly having the chance to work for a recognized company(In my case Apache) and the global reputation a gsocer can have is so motivational. Also getting started to work with a strange team, getting to know them, work remotely, add good experience to life and high professional value as I guess. It's amazing to work with the community. Also it is a great chance to broaden the horizons in technical skills while having guidance from an expert in the area, having hands on it.

Also I'm glad to share about my project, which is to implement 'W3C XML Digital Signatures for Widgets Specification in Apache Wookie. Computer Security has become the favorite field of me followed by Big data after my internship at WSO2 Lanka(pvt) Ltd, with experience I had …
