My Python Development Environment, 2020 Edition 1 week, 1 day ago

For years I’ve noodled around with various setups for a Python development environment. A couple of years ago I wrote about a setup I finally liked; this is an update to that post. Bad news: this stuff still isn’t stable, and I’ve had to make some changes. Good news: the …

My questions for prospective employers (Director/VP roles) 7 months ago

Last time I was looking for a job, I wrote up a list of questions I wanted to ask prospective employees. I just ran across the list again, and figured I’d share. I was looking for a senior management role (Director/VP-level) in Engineering or Security, so the questions are sloped …

IQ isn’t enough to get hired 7 months, 3 weeks ago

I’ve interviewed hundreds of people for technical roles, and a pattern has emerged. In general, we reject many more candidates for social skills than for technical competence. In fact, most technical interview funnels are arranged so that technical screens are earlier. This means that if you reach an interview, you’ve …

📌 Kore4 and Python

There’s a bunch of interesting stuff here—async, automatic ssl—but the seccomp stuff is _really_ fascinating. I wonder how hard it’d be to do this with Django? #

📌 Design better data tables - UX Collective

I really like these patterns. I wonder if there’s a good front-end library that makes this stuff easy? I tend to use django-tables2 on the backend, which handles all the sorting/filtering nicely, but the UI leaves something to be desired. #
