Genies give you a degraded facsimile of the mediocre code they trained on. Two axes: features (works or it doesn't) and futures (optionality). The genie drifts down-and-to-the-left, plausible "success" on broken code. Awareness is step one: newsletter.kentbeck.com/p/genie-tarpit

I get a chuckle when the App Store warns me about a 2MB download on mobile. You couldn’t even fit a Golang hello world in that.

Does anyone watch for OOMs in their #k8s clusters? I do and am a little surprised how often default OSS project containers OOM. Not sure anyone is setting their Golang memory settings at all.

Seems like a lot of Japan is still on the other site. Thinking maybe I’ll make that Japanese only and this will be English.
