Using IFTTT to handle future and recurring tasks

Store the tasks in our "GFR Tasks" Google calendar.
- Relatively fine grained control over dates of tasks (e.g. second Wednesday of each month)
IFTTT applet turns these events into cards in Trello
- Our applets
- "If any event starts on GFR Tasks, then create a card in - Go Free Range board"
- Fires 15 minutes before the start date of a task, i.e. 23:45 for all day tasks

Virtualenv's `bin/activate` is Doing It Wrong

I'm a Python programmer and frequently work with the excellent [virtualenv][] tool by Ian Bicking.

Virtualenv is a great tool on the whole but there is one glaring problem: the activate script that virtualenv provides as a convenience to enable its functionality requires you to source it with your shell to invoke it. The activate script sets some environment variables in your current environment and defines for you a deactivate shell function which will (attempt to) help you to undo those changes later.

This pattern is abhorrently wrong and un-unix-y. activate should instead do what ssh-agent does, and launch a sub-shell or sub-command with a modified environment.

How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb
