I have a function that takes a slice, appends a couple of elements and returns the result. The caller keeps its own slice and uses the returned one separately. Sometimes the caller's original slice has changed…
Roughly 600k lines of Go in a single module, one repo, VS Code on a 16GB laptop. Opening the repo root has gopls climbing to several gigabytes within a few minutes and then completions start taking two or three seconds…
Express in front of Postgres, one 2 vCPU box, restarts itself nightly which is the only reason we do not fall over. Resident memory starts around 200MB after a deploy and is comfortably over a gigabyte by the evening,…
Single process, twelve goroutines all incrementing one int64, and a metrics endpoint that reads it once a second. I keep going back and forth between a around the field and a dedicated goroutine owning the value with an…
Three backend developers, all comfortable in Python and nothing else. The service takes roughly 3k JSON messages a second off a broker, validates them and writes batches to Postgres, and it currently needs four boxes to…
My storage package has . The repo layer returns and the handler checks to decide 404 vs 500. It works on the direct path but returns false whenever the call goes through a small retry helper I wrote. Go 1.22, no build…

Eight workers pull jobs off a buffered channel (cap 100) and push results onto an unbuffered results channel. On SIGINT I call then , and roughly one run in three it just sits there forever instead of exiting. Each…
Four endpoints, one Postgres query, no fancy dependencies as far as I know. gives me 14MB, which surprised me because everyone talks about Go producing small self contained binaries. Coming from Python where the file is…
