Adding CarPlay to a 2017 Chev SS (US version of the 🇦🇺 VF Holden Commodore SS)
So, I recently treated myself to a 2017 Chevy SS, which is a rebadged VF Holden Commodore SS. For context, the Chevy SS was sold in the United States from 2014–2017 and is mechanically identical to the Australian VF Commodore SS. I owned a 2003 VY SS back in the 2000s, and this was Holden’s […]

If you’ve ever stared at a Linux box hanging at boot for 90 seconds waiting for "network to be configured" and wondered which interface is the holdup, congratulations — you’ve joined the rest of us in systemd-networkd-wait-online purgatory.

Python pip ‘editable’ installing
From time to time I get asked (and I even have to ask a coworker) for the best way to install a Python modules (especially ones with entry points) into a virtualenv and still edit / develop with them. It seems pip install’s ‘-e’ is very unknown. pip install -e /path/you/are/editing Will allow you to develop […]
GitHub + Rebasing from upstream/master to origin/master
