Thinking of becoming one of those eccentric computer hermits who mostly use their own software and libraries, in a Frankensteinian amalgamation of tech no one else understands

HTTP/3 just surprised me - I just did a pretty simplistic test (firing off 50 requests from the frontend vs. batching 50 requests on the backend). I expected to see a much slower response for the non-batched requests

A screenshot showing two buttons, one labelled "multiple" and one labelled "batch". The multiple button has a 1143ms timestamp below it while the batch button has a 1149ms timestamp.

We’ve raised $100M at a $1.5B valuation. We built @render.com to give developers an intuitive path to reliable and scalable cloud infrastructure. Now, we are bringing that same philosophy to long-running, stateful infrastructure for AI apps & agents. 🧵

Parsing JSON in go is such a minefield. Oh you wanted numbers other than float64? Better remember to UseNumber or you might get a runtime error!

This week’s high‑profile outages made headlines, but the 2025 Uptime Institute Outage Analysis shows a different picture: overall data center outage frequency and severity keep declining even as the need for infrastructure explodes.

When a shiny new bit of tech is released I like to find the version that IBM built a decade ago as reference material - what limitations did it have? How did it evolve?
