KeePass v2.x (KDBX v3.x) file format
Convention: Byte array notation as it would appear in a hexeditor.
= Layout=
KDBX files, the keepass database files, are layout as follows:
1) Bytes 0-3: Primary identifier, common across all kdbx versions:
private static $sigByte1=[0x03,0xD9,0xA2,0x9A];
2) Bytes 4-7: Secondary identifier. Byte 4 can be used to identify the file version (0x67 is latest, 0x66 is the KeePass 2 pre-release format and 0x55 is KeePass 1)

nodejs clustering, zero downtime deployment solutions

Clustering: The basics

The trick? pass the file descriptor from a parent process and have the server.listen reuse that descriptor. So multiprocess in their own memory space (but with ENV shared usually)

It does not balance, it leaves it to the kernel.

In the last nodejs > 0.8 there is a cluster module (functional although marked experimental)

Node.js TCP client and server example
/*
In the node.js intro tutorial (http://nodejs.org/), they show a basic tcp
server, but for some reason omit a client connecting to it. I added an
example at the bottom.
Save the following server in example.js:
*/
var net = require('net');
