Do you read directly from the manuscripts, or do you transcribe them into more legible formats for playing? As a violinist I find historical handwritten manuscripts incredibly hard to sightread compared to modern engraving, but I'm cur

In real life this tends to happen in reverse (climbing a mountain rather than descending), since it's generally easier to go up than go down. Reading accident reports, a common theme is people setting on what they think is a class 3 or

Tailscale is amazing. I was able to set up our AWS VPN with it in <30 minutes, and it's just worked ever since. Getting new users set up is similarly seamless. If this means I continue to forget how to run OpenVPN I consider that we

Hey everyone, I'm the co-founder of Arroyo and excited to see this posted on HN! As a bit of background, Arroyo lets you build real-time data pipelines with SQL, providing subsecond results over millions of events/sec. This is the

This sort of works, but is finnicky to set up in each environment and introduces the risk that you forget to update it and your queries are broken.

We originally used SQLx but eventually moved away for a couple of reasons: * The sqlx::query! macro is a neat hack, but the fact that it calls out to a database in a proc macro is pretty insane. It significantly slows down compilation with

The Narrow Bank proposed a structure like this, where they would take deposits from customers and just park them at the fed, passing along the fed rate minus a small cut. This is more or less perfectly safe: the Fed basically defines what a

I don't really agree with that framing. Most of the languages people use to write web apps are safe! The actual tradeoff rust is making is that performance is more important than developer productivity. It's not willing to sacrifi
