The Art of Java: Tracking excessive garbage collection in Hotspot JVM

http://artiomg.blogspot.com/2012/06/tracking-excessive-garbage-collection.html

The Art of Java. Saturday, June 9, 2012. Tracking excessive garbage collection in Hotspot JVM. Quite frequently due to memory leaks or other memory problems applications freeze leaving only the garbage collector (GC) process running unsuccessfully trying to free some space. This happens until watchdog (or frustrated administrator) restarts the application and the problem is never solved. Using following flags we can direct Hotspot JVM to throw a heap dump when an application becomes GC driven. The policy...

Java is the new C. High performance Java, realtime distributed computing, other stuff. Tuesday, October 28, 2014. The Internet is running in debug mode. With the rise of the Web, textual encodings like xml/JSON have become very popular. Of course textual message encoding has many advantages from a developer's perspective. What most developers are not aware of, is how expensive encoding and decoding of textual messages really is compared to a well defined binary protocol. Of energy (global warming anyone?

http://javadots.blogspot.com/2010/08/repeat-after-me-immutable-objects-will.html

Java: Developing On The Streets. Repeat after me: Immutable objects will not slow you down. As noted by Stephan Schmidt. The advent of functional programming promotes the use of immutable objects even in non-functional languages. Immutable objects have many positive traits: they are safer, they throw less exception, they are not prone to problems of covariance, they prevent races when used in a multi-threaded settings, etc. In certain cases (such as: many object holding references to x) this rerouting ma...
