SSH Agent Forwarding

This is part of the mini-series OpenSSH for Devs.

SSH agent forwarding let’s you lock down remote hosts while making them easier to access and use in automated ways. One co-worker succinctly describes agent forwarding as “the shit”.

SSH Config

This is part of the mini-series OpenSSH for Devs.

An SSH config let’s you set options you use often (e.g., the user to login as or the port to connect to) globally or per-host. It can save a lot of typing and helps make SSH Just Work.

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).

Brewer's CAP Theorem

Starting with the punk rock creation story, Brewer’s CAP Theorem 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.

Released Virtualenv Burrito 2
