Using OTP's observer (appmon replacement) remotely

$ ssh remote-host "epmd -names"
epmd: up and running on port 4369 with data:
name some_node at port 58769

Note the running on port for epmd itself and the port of the node you're interested in debugging. Reconnect to the remote host with these ports forwarded:

$ ssh -L 4369:localhost:4369 -L 58769:localhost:58769 remote-host

This list now exists over at http://juliepagano.com/blog/2013/11/02/101-off-limits/ and will be updated there.

I keep saying that impromptu, unwanted feminism 101 discussions are exhausting and not a good use of my resources. Then people ask what I mean by 101, so I'm starting to make a list. This list will change over time - I recommend checking back.
