Syntax

All target selectors start with @. The following character is the selector type. For example, @p means 'closest player'.

Target selectors may have additional, optional arguments. You can specify these in [ ], using the syntax a=0. For example, @p[a=0,b=5,c=-500].

There is a special short syntax for just specifying x, y, z and r arguments; simply list their values separated by a comma, without x=. For example: @p[100,64,-100,5] for 5 range, x=100, y=64 and z=-100. Each of these are optional and skippable by leaving them empty. For example, to just specify y coordinate: @p[,64].

Global Arguments:

x - X coordinate for search center. Default is senders coordinate, or 0.
y - Y coordinate for search center. Default is senders coordinate, or 0.

OpenSSL Base64 Encoding: Binary Safe and Portable

Herewith is an example of encoding to and from base64 using OpenSSL's C library. Code presented here is both binary safe, and portable (i.e. it should work on any Posix compliant system e.g. FreeBSD and Linux).

Cryptographic Best Practices

Putting cryptographic primitives together is a lot like putting a jigsaw puzzle together, where all the pieces are cut exactly the same way, but there is only one correct solution. Thankfully, there are some projects out there that are working hard to make sure developers are getting it right.

The following advice comes from years of research from leading security researchers, developers, and cryptographers. This Gist was [forked from Thomas Ptacek's Gist][1] to be more readable. Additions have been added from

	In the node.js intro tutorial (http://nodejs.org/), they show a basic tcp

	example at the bottom.
