The Linux Programming Interface: A Linux and UNIX System Programming Handbook (Michael Kerrisk) I've found The Linux Programming Interface to be one of the best in-depth books I've ever tried to read on Linux.

9) The Linux Command-Line.
Have a look at The Linux Command-Line. The book focuses on novice users and the extended version is free for download.

Difference between static initializer block vs instance initializers in Java? Example
In Java, you can initialize member variables or fields in the same line you declare, in the constructor, or inside an initializer block. There are two types of initializer blocks in Java, static initializer block to initialize static variables and instance initializer block to initialize non-static fields. As the name suggests, the main difference is their purpose, instance initializer block if for instance variables, and static initializer block is for static variables. Another key difference between them is the time of execution.

I compare Joins in SQL with Recursion in programming in terms of confusion because I have found that these two topics are special in their nature and you can't get it right with casual reading until you understand the concept and its various well. Things get worse when the table locked due to such SQL Join queries which were fired without knowing how much time it would and how big the result set could be.
