Project mention: When deployments are easy, code becomes simpler | news.ycombinator.com | 2023-09-05

I wanted a very simple feature flagging solution, so I wrote my own with Google Sheets as the backend: https://github.com/stillmatic/flagsheet
It's slightly more complex than a code push but still very easy to use.

Project mention: The Case of a Leaky Goroutine | news.ycombinator.com | 2024-03-25

I wish Go recorded the timestamp of goroutine and let you access them.
An app I work on recently had a bug where goroutines would slowly build up over time. Turns out the bug is in the Growthbook SDK [1]. We can monitor the number of goroutines, but having a large number of goroutines waiting in the location that gets stuck is normal — we can only see such a problem over multiple days, in that the minimum value slowly goes up.
If Go could tell you the timestamp of the oldest goroutines as part of the pprof dump, we could have an alert, and it would work for any such leak.
