Things written in times past
I used to write things for a previous employer's tech blog, but the old URLs may succumb to bitrot. These should work as long as Medium works:
The challenges of running a betting exchange (2016)
Notes on interviewing engineers (2016) -- This one was also picked up by a recruiter's blog.
DevOps is culture, not a title prefix (2017)
Security and Devops - a natural fit (2017)
Wait, what is my fleet doing (2018)
