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…

MIT - AITI experience

How I got the chance to join I got the chance to join the MIT-AITI (which was Massachusetts Institute of Technology, African Internet Technology Initiative and now goes as Asian ) program while I was completing my internship period of 24 weeks. Thank to WSO2, where I was having my internship I could get a release to join the program for 6 weeks and I am writing this just after the 2 week of the AITI program. As I feel that I have used that time effectively, hope to keep a note on what I got. Today was a more challenging and interesting day and it will be worth to have a note on what I have done in the course so far. An overview on the course can be found in the given link.


Very first day At the very first day we were emphasized on the purpose of the course is not just to teach us mobile technologies, but also to make people use them as real applications. In brief we were at the beginning of becoming entrepreneurs initializing a company based on mobile applications. Honestly I felt whethe…
