I hate GMail, but sometimes you gotta. They're notoriously awful at deleting lots of messages at once, as their own search engine will tell you. I had more than 1,000,000 messages I needed to purge and couldn't do it using their own tools. So I wrote my own.

## this is a total hack.  acbuild needs systemd-nspawn.  initially, I tried
## running the go agent in a rkt container, but failed for reasons I forget
## right now (overlayfs problems?).  then I ran into more problems with systemd-
## nspawn on CentOS 7.1, and I forget the origin.  we're getting closer: in
## CentOS 7.2 I'm able to run acbuild as root outside of a container.  but when
## running within the go agent, systemd-nspawn is killed for no discernable
## reason.  so, we're back to faking out acbuild by providing this systemd-
## nspawn-alike.

Description

OpenELEC runs Kodi, an award-winning free and open source (GPL) software media player and entertainment hub for digital media. For more info see http://kodi.tv . The base system has been designed and built from the ground up to be as efficient as possible – consuming only tiny disk and memory footprints and providing cutting edge hardware support to deliver a set-top box experience.

In order to run software above the base OpenELEC distribution with minimal impact to the OpenELEC base, one alternative is to use a container.

I have chosen to use systemd-nspawn instead of chroot. There are really no downsides as long as you can configure the required kernel config options and have a basic working knowledge of systemd.

Transforming Code into Beautiful, Idiomatic Python

Notes from Raymond Hettinger's talk at pycon US 2013 video, slides.

The code examples and direct quotes are all from Raymond's talk. I've reproduced them here for my own edification and the hopes that others will find them as handy as I have!
