exec: "/bin/sh": stat /bin/sh: no such file or directory (or maybe exec: "/bin/bash" ?)

	Are you suffering from this cryptic error?
	Are you somewhat familiar with docker but flailing around lost with what could be causing this issue?

	Are you trying to export an image somewhere on docker, and import on another machine, and it seems straightforward enough?

	Then what you probably did on machine was:
	docker save randomimage > foo.tar

	and then on the other machine
	docker import foo.tar foo

IO::WaitReadbale has not initializer. Makes mocking and stubbing in minitest hard and annoying

	# example to stub out IO::WaitReadable. Spent forever figuring this stupid one out.

	class MyError < StandardError

	# function to test
	def start_ssl_server
	begin
	@server.accept
	rescue IO::WaitReadable
	rs,ws,es = Kernel.select([@server], [@server], [@server],10)

bitcoin addresses for wanacry ransomware

	quick hack to extract bitcoin address (OS X):
	strings -n 34 FILENAME \| grep -E '^.{34}$'
	better hacky shell script:
	strings FILE \| grep -E '^[13][a-km-zA-HJ-NP-Z1-9]{25,34}$'
