Installation

mkdir -p ~/.config && touch ~/.config/ssh-agent.pid
Paste the contents of ssh-agent-manage.sh into your .bashrc or .bash_profile or similar
killall -9 ssh-agent
Start a new terminal session (note: old sessions will not see ssh-agent, only new ones)

Details

This snippet, when included in .bashrc, will ensure that your session has a working ssh-agent with all your ssh keys loaded into it. It does this without creating separate ssh-agent processes by:

Migrate Home Assistant’s sqlite database to MySQL, specifically MariaDB (10)

After having added a decent amount of entities to my Home Assistant setup, the user interface—especially the history tab, but also the history for each entity—became very sluggish. Having to wait for up to 30 seconds to see the history graph for a single entity became the norm with an sqlite file weighing in at 6GB and millions of entries in the “events” and “states” tables.

I wanted to keep my acquired data, so I had to migrate it from the current sqlite file to a MySQL database instead of starting anew. I’ve done this using Home Assistant version 0.81 and MariaDB 10. Some parts might change in the future.

Making a UEFI bootable iPXE USB drive

Build the UEFI executable for iPXE

# First we'll clone iPXE
$ git clone git://git.ipxe.org/ipxe.git
# Go into the src directory of the cloned git repo
$ cd ipxe/src
# Compile the UEFI iPXE executable

This is a little trick I use to spin up the packages instalation on Debian/Ubuntu boxes in Vagrant.

I add a simple function that checks if a directory named something similar to ~/.vagrant.d/cache/apt/opscode-ubuntu-12.04/partial (it may have another path in Windows or MacOS) and create the directory if it doesn't already exist.

def local_cache(box_name)
  cache_dir = File.join(File.expand_path(Vagrant::Environment::DEFAULT_HOME),
                        'cache',
                        'apt',
                        box_name)
