Next question:

Since I try to stay off of Twitter and don't post any more content over there please suggest some accounts I should follow here. My timeline needs some more content :D

I messed up my gotosocial instance here at threatactor.club, it's running on fly.io and a very long migration was interrupted by a health check.

I was fiddling with the sqlite DB for a while and tried to recover that mess... until I noticed that there are automated snapshots of the volume which holds the DB, daily with five days of retention. Huge props to fly.io for saving my virtual ass with this.

I'm open for Ruby on Rails contract work in 2025!

I'm an experienced systems and performance engineer with deep knowledge of Rails and the Ruby VM, and I have code committed and CVEs credited in both projects. I am also highly proficient with web tech, databases, and Linux systems.

I've worked at every layer of the stack from kernel to browser frontend, and I'm comfortable with cracking open the code to answer questions the documentation doesn't.

From 2013 to 2018 I worked on systems and performance at GitHub, where I led efforts to upgrade the main Rails app from Rails 2.3 to 3.2 (old heads know) and from Ruby 1.9 to the 2.x series.

I'm based in Melbourne, Australia and am experienced and comfortable working remotely, however I am also open to hybrid arrangements if you're local.

Available for immediate start on short-to-mid-term contracts. DM here, or reach out via email at hailey@hails.org.

boosts appreciated :)
