Day two of vibe programming with Cursor. I don't get the hype. This is...terrible. The model regularly gets lost in my file system, fails to use its own internal API, overwrites existing things like migrations, outputs half completed modules. Is this thing an iPhone 4? Am I just holding it wrong?

TV Labs has been going through a major growth period onboarding multiple customers (some big, some small) in the last 3 months. @honeycomb.io has been an invaluable tool, helping us isolate dozens of issues. Read my post on how to get started if you're not using it 👇 davelucia.com/blog/observi...

I was recently perusing the Phoenix codebase (as one does), and loved how `Phoenix.Logger` handles its own telemetry data to log statements. It's brilliant! It centralizes logging so you don't have duplicative `Logger` and `:telemetry.execute` statements!👇

A recurring piece of advice, that while with hindsight upon thinking about it seems obvious, but that has been very helpful when I bring it up this past couple weeks: "Slow down, and read the output from the program in your terminal" The effectiveness of this advice has been astoundingly high.

Where do you all go for home office design inspiration? Colors, rugs, furniture, art, etc. Not desk stuff. I'm in a mostly empty weird green room and need to fix it. 😅

I actually have a theory that strict SemVer adherence hurts marketing and adoption. The mob loves major version bumps and lack of major version bumps may give a false sense of staleness to a project.

Giving myself a 2025 gift of a calm inbox. Deleted 66k emails and unsubscribed from a hundred different email lists. Some of those lists were probably good, but damn, the signal to noise ratio on email is _so_ bad.

"From upcoming Elixir 1.18 > For example, you can invoke IEx.configure(auto_reload: true) and IEx will automatically reload modules changed elsewhere, either by a separate terminal or your IDE. This is beautiful! 😍 #ElixirLang" @hugobarauna.com
