NPTEL - C course completed successfully

IITs and IISC together have created a wonderful NPTEL program i.e. National Program on Technology Enhanced Learning. There are tons of recorded lectures for almost all the engineering streams. A very good resource for the 4 year engineering and also for many competitive exams like GATE.

Scripture My Hopes by Ibrahim Jaaber

i want to know mecca to medina by foot but i'm too busy with life
i want to know abraham like a father and i'll be the sacrifice
i want to know jerusalem like the true followers of christ

The Weakest of Homes 29:41

(For the programmers) You need to pick your side

Let me state a fact, you spend time a lot of time on the internet reading about debate between design features of various programming languages, there pros and cons, why one language is better or should be preferred over the other. It's just not very relevant. You'll be lost for long and just won't get up and do something if you don't quit the above described behavior.

Java memory analysis using inbuilt tools

jhat(Heap Analysis Tool) is a tool that comes along with the jdk and is present under jdkxxx/bin/ .

There are two way to get the heap dump

1. Give it while starting the java program as
java -Xrunhprof:format=b,file=file.hprof class-name
2. Get the heap dump using jmap as

jmap -dump:file=file-name process_id

Here I am using the first method. The java code ran is the same as described in this post about Thread-Creation-Time.

Java analyzing thread creation time

In Java, the thread creation time increases with the number of thread that are already created, hence it is advisable to keep the thread count minimal and only create a Thread when actually needed.

The below gist is a minimal piece of java code that helps in proving this
