If you make a good code and build a bunch of things on top of it, but find out it wasn’t matched to a use case and need to move to a new architecture, that good code is going to be a pain to remove or change. “Good” shouldn’t be conflated w

simdjson can load the json into memory in a queryable form in ~1/3 of a second. So you can save yourself basically 40% of the runtime right there. Computing average should take less than 1/2 a second on modern hardware (assumes &l

Construction time is dominated by staging materials (shipping, delivery, and movement of those materials around on site and into place), and sync points. Houses will sit for weeks waiting on a chain of specialists to get time to finish some

When I look up something twice, having a “go to page” function is sorely lacking in modern apps. I want to flip to page 300, and they never do that anymore.

Fundamentally, copyright is the government promising to beat up anyone that copies a protected work. Now, we don't live in a complete dystopia, so it's not literal beatings. It's legal protection and the beating up is the inf

Yes, it’s possible. Obviously things won’t get back to the VGA levels of size because we have higher resolution everything. But you can get similar results by thinking in terms of a memory budget, CPU budget, etc. and then measuring to make

OP missed a category really. If there are any consistent sync points in the day with the whole team, that creates “core hours” where everyone is expected to be in during those, but otherwise the hours are whenever you want. Maybe call it 3.

I love the “properties” bit. You can get the same functionality by just defaulting the fields on your classes to public. 99% of the time, the getters and setters aren’t doing anything, just proxying the variable.

Let the government compete with private insurers, and that will be a step in the right direction. The further steps that meaningfully reduce per-capita spending... those are all way harder, which is saying something.
