Sound familiar?
• Faster iteration
• Fewer humans → higher risk of failure
• Limited applicability

Auto belayers (ahem, AI) are great tools — but there are still many reasons to keep humans in the loop. Not taking over everything… yet.

The tradeoffs? Faster iteration, but less safety redundancy and less social interaction. No second human to double-check or brainstorm with. Also: limited environments - indoor gyms, preset routes, not outdoors.

Then came auto belayers: devices attached to the wall or ceiling that manage the rope automatically. You can climb solo and do rapid repetitions without another human in the loop.

Generalizing a bit: in most climbing I’ve done, you climb as a pair: a lead climber and a belayer. The belayer manages the rope, double-checks safety, and offers advice or encouragement from the ground.

Huge kudos to the DistrictCon organizing team for pivoting to host as much of the conference as possible online with the anticipated travel disruptions due to snow. ❄️

If you’ve got any favorite tools or tricks for keeping Rust compile times down, I’d love to hear them!

🎯 Answer: The original Rust compiler from 2010 was written in OCaml! 🐫

OCaml was chosen for its strong type system and pattern matching features. This "bootstrap" compiler was used to create the first self-hosting Rust compiler.

Fair point, but the benefits would include speed and efficiency: faster cold starts, lower memory usage, smaller deployment packages

And it looks like the upcoming 3rd edition is changing the 3rd variable to:

`let disapproodles = "ಠ_ಠ"`
