 The saying “if it doesn’t exist on the Internet, it doesn’t exist”[1] is ringing truer every day. Nowadays, it is hard to imagine most businesses without an e-commerce platform, let alone without a web presence at all.

 Adding more memory to your JVMs (Java Virtual Machines) might be a temporary solution to fixing memory leaks in Java applications, but it for sure won’t fix the root cause of the issue. Instead of crashing once per day it may just crash every other day. “Preventive” restarts are also j...May. 10, 2013 01:45 PM EDT Reads: 1,848 |

 Abstractness is a measure of the rigidity of a software system. Higher the abstraction, lower the rigidity (or greater the flexibility) and vice versa.
