Since Java 7 it has been possible to use one or more underscores (_) for separating groups of digits in a primitive number literal to improve their readability. For instance, these two declarations are equivalent: Java SE 7 int i1 = 123456; int i2 = 123_456; System.out.println(i1 == i2); // tru...

To produce nested JSON object, you need to simply add one JSON object to another: JSONObject mainObject = new JSONObject(); // Host object JSONObject requestObject = new JSONObject(); // Included object try { requestObject.put("lastname", lastname); reques...

Bootstrap's grid system has 12 units known as Columns that can be used to layout content horizontally across the viewport. The reason for a 12-unit grid (instead of 10, 16, etc..) is that 12 evenly divides into 6 (halves), 4 (quarters) and 3 (thirds). This makes adapting to a variety of layouts muc...

A common problem when working with Unity is when 2 or more developers are modifying a Unity scene or prefab (*.unity files). Git does not know how to merge them correctly out of the box. Thankfully the Unity team deployed a tool called SmartMerge which makes simple merge automatic. The first thing...

Padding Remember, members of a struct are usually padded to ensure they are aligned on their natural boundary: struct t { int a, b, c, d; // a is at offset 0, b at 4, c at 8, d at 0ch char e; // e is at 10h short f; // f is at 12h (naturally aligned) lo...

In an enum it is possible to define a specific behavior for a particular constant of the enum which overrides the default behavior of the enum, this technique is known as constant specific body. Suppose three piano students - John, Ben and Luke - are defined in an enum named PianoClass, as follows:...

A typeglob *foo holds references to the contents of global variables with that name: $foo, @foo, $foo, &foo, etc. You can access it like an hash and assign to manipulate the symbol tables directly (evil!). use v5.10; # necessary for say our $foo = "foo"; our $bar; say ref *foo{SCAL...

open(my $fh, '<', "/some/path") or die $!; my @ary = <$fh>; When evaluated in list context, the diamond operator returns a list consisting of all the lines in the file (in this case, assigning the result to an array supplies list context). The line terminator is retained, and ...
