I gave commit rights to someone I didn't know (2016)
(Spoiler: trusting your contributors works) Some years ago, I polished up and released an abandoned project for storing financial data in Django. It let you declare “Money” fields on your models, dealing with proper storage and currencies for you. My use case for the library, django-money eventually faded, but it…

YouTube Face is clickbait, attaining human form
On YouTube, there’s a long tail of content that pretty much guarantees the inclusion of every potential human interest.

A year of funded FreeBSD development
For several years leading up to this point I had been talking to Amazonians on and off about the possibility of Amazon sponsoring my FreeBSD/EC2 work; rather predictably, most of those conversation ended up with my contacts at Amazon rhyming with "Amazon should definitely sponsor the work you're doing... but I don't…

What Startups Are Really Like
October 2009 (This essay is derived from a talk at the 2009 Startup School.) I wasn't sure what to talk about at Startup School, so I decided to ask the founders of the startups we'd funded.

Is developer compensation becoming bimodal?
Developer compensation has skyrocketed since the demise of the Google et al. wage-suppressing no-hire agreement , to the point where compensation rivals and maybe even exceeds compensation in traditionally remunerative fields like law, consulting, etc. In software, "senior" dev salary at a high-paying tech company is…
