OpenSSH for Devs

There have been many surprises as I’ve moved from Sysadmin to Coder. Some of them are a product of switching contexts: what was once “common knowledge” is now “tips & tricks” (and vice versa). One tool that has regularly come up is SSH. It can be painful to watch developers jump through unnecessary hoops (over and over again) in order to access remote hosts.

In that light, presented here is a short series of posts covering useful OpenSSH features for developers. My peers and I use these everyday and it’s made our jobs easier.

Brewer's CAP Theorem

Starting with the punk rock creation story, discusses the fascinating, proven, theorem that you can’t have all three of consistency, availability, and partition-tolerance in a distributed system.

A very interesting follow-up is: A CAP Solution (Proving Brewer Wrong). It approaches the problem by dynamically guaranteeing different CAP properties instead of trying to guarantee them all at once.
