There are three easy to make mistakes in go. I present them here in the way they are often found in the wild, not in the way that is easiest to understand.
All three of these mistakes have been made in Kubernetes code, getting past code review at least once each that I know of.
What do these lines do? Make predictions and then scroll down.

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

If you are adventurous, here the process to have Hipchat working in your favourite IRC client:
First, you need to install the IRSSI XMPP plugin. You can find this package in your distribution, but I advice you to use the latest version possible if you don't want this segfault errors everywhere: http://gna.org/bugs/?20487
The first version released after the patch fix is the 0.52-2 that you can download here: https://launchpad.net/ubuntu/+archive/primary/+files/irssi-plugin-xmpp_0.52-2_amd64.deb (No dependencies so it should work in any Debian distributions)
Once it's done. You have to configure IRSSI. Either via command line, either manually in the ~/.irssi/config file. I followed this thread: http://cybione.org/lists/irssi-xmpp-list/msg00339.html and it was pretty successful.
You can find your XMPP access on your HipChat account on this page: https://boxuk.hipchat.com/account/xmpp. Everything has a XMPP account id. Even the Rooms name. So you have to use these instead of the real names for your I
