ssd maintance / types of flash memory storage

	#
	# SSD's and flash memory is available in a variety of different flavours.
	# As power drains from souch a system you stand to lose those bits!
	#
	# Firmware plays an important role in all of this.
	#
	# If your SSD is not powered up then the firmware will not be able
	# help you out. Most firmware is propriortary and as such, you can
	# power the drive up for a while (...?...) and hope for the best.

ssh tunnel cheatsheet

	#
	# ssh using the -N falg for establishing a tunnel is great.... but somtimes it is difficult to know if authentication has
	# been successful (especially if you have any kind of extended login delays setup on a remote system) and you are
	# authenticating with a password (did I type that correctly).
	#
	# this approach requires little additional setup and prevents lots of verbosity regarding the login.
	#

	# recive notification that authentication succeeded - bash
	ssh -v <user>@<remote-host> -p <port> -L <localport>:<tunnel-host>:<remoteport> -N 2> >(grep Authenticated >&2)
