Great article, lots of tools I didn't know of. Can you provide more info about where I can get that 2g chip outside the states? Sounds very useful to use a service like that.
Also, can you expand a little bit more about the slack integrations? I can't imagine something more than simple notifications for services like github, but you described it as it "changed your life", so I'm assuming you found ways to automate your daily life with integrations.
