Which end? This moves one end to reach frontend code

I like to ask for a code tour using snippets of the most important types and functions. Much better to read through

I think this could have used tigerbeetle instead?

I came here to make a similar comment. It seems like TigerBeetle was built for exactly the type of transactional processing this post is about?

We need Amdahl's law for limbs

Power law:

The number of people decrease as a power of the distance you travel away from popular spots

The NPS has an even more specific version of this: the overwhelming majority of Americans visiting a park will not walk more than 1/4 mile from their vehicle. So everything is designed to reinforce this behavior as much as possible, which (a) means that the majority of people get a richer, more dramatic and/or more informative/eye-opening visit (b) the backcountry is left alone, both for the other animals that live there and for the rare humans who will head out there.

It doesn't help that basically all the hikes in Zion are popular hikes. There was definitely waiting involved in the Angels Landing hike and that was well beyond 1/4 mile from the parking lot up a significant incline before you even reach the chains to begin climbing up. Lots of passing and waiting once you hit the chains. Tons of people. The very top was quite crowded but we went before the permitting system was in place.

Goodhart's law: "When a measure becomes a target, it ceases to be a good measure"

You still lose the benefits of Affine Types in Rust though

It can be type safe and testable with free monads

That's why I love the Readex Pro font. It also has glyphs for Arabic and a lot more languages in the same file, so I can use one font file for everything.

You can also use jbang to run java scripts with dependencies
