Usage: asg-connect DESCRIPTION

The asg-connect command will search for Auto-Scale Group instances that match the description. The first instances will be selected and you will be SSH'd into it.

Switch Stream

The switch stream multiplexes an readable stream across a series of writable streams. All streams operate in object mode, meaning read and write events emit whole objects instead of buffers.

Usage

var sw = new Switch();

NodeOS Init

History

Init is the first process launched on boot that is not in kernel space. Init runs as the root user, but it is still a user land process. Init has a process-id, it can be sent signals, and uses standard syscalls to interact with the kernel.

What makes init special is that it is essentially in charge of booting the operating system. During the boot process

	[14:52:47] groundwater: and i'm just playing around with various approaches to find the best fit
	[14:52:59] trevnorris: groundwater: then the actual proper way to do this is create an ObjectTemplate, set the InternalFieldCount = 1
	[14:53:21] trevnorris: then use SetAlignedPointerInInternalfield
	[14:53:43] trevnorris: oy, again. SetAlignedPointerInInternalField (int index, void *value)
