Sudoku*. Suu means numbers in Japanese and Doku means solving here. So literally "number solving".

In 10 years this will be a "that's how I would've done it 10 years ago too...or?? I don't remember"

Defending that particular kind of driver: He might not have known to be the last car. But one thing he knows for sure: a long line of cars in front of him. Speeding up or keeping distance is pointless, so he uses that moment to be friendly instead.

i prefer predictability to friendliness every time

How do you recover democracy when you reunite with a non-democracy?

Chinese folks describe and feel their country as democratic. So it is democratic. Problem solved!

I just read "THE MEMOIRS OF THE CONQUISTADOR BERNAL DIAZ DEL CASTILLO WRITTEN BY HIMSELF"

It's not fiction but it feels like a time warp into a world unimaginable.

Store data persistently so it can be looked up efficiently* sounds like a single problem.

Definitely two.

"Store data persistently" implies "it can be looked up" since if you cannot look it up it is impossible to know if it is stored persistently.

The "efficiently" part can be considered a separate problem though.

Well, if you just want to store data, you can use files. Lookup is a bit tedious and inefficient.

So, if we consider that persistent storage is a solved problem, then we can say that the reason for databases was how to look up data efficiently. In fact, that is why they were invented, even if persistent storage is a prerequisite.

How about "store data in certain way." That sounds more like 1 problem and encompasses an even larger problem space.

It’s not persistent if it can’t be recovered later

Not necessarily, opinions vary.

Having had grandparents live through WWII (or any other war to be fair) also helps instill this attitude. I can barely imagine what kind of famines they had to endure.

What about LLM training? What about training all the discarded or unused LLMs?
