Ancestors

I just completed "Disk Fragmenter" - Day 9 - Advent of Code 2024 #AdventOfCode in #ruby

I abandoned a whole strategy (stuck at off-by-1s) and tried a completely different approach.

Toot

@oinak

A bit lengthy, but written so clearly that I understood what you did, despite not knowing Ruby at all.

I guess, nobody said that about my code I publishes this morning. 😁

Good job!

@mina I had a "clever" version all doing math on indexes/size/values vecause I feared the unfolded-input-size memory impact... but I got stuck on off-by-ones and my brain was oozing out my ears, so I scraped it all and started anew prograing ruby the way I like, very semantic/domain-close, not very perf-oriented.

It took 20s on part 2, so "good enough".

Reading your code I get nostalgic, I learnt Perl long before Ruby (but used it much less) and still see its influence often on ruby's ancestry

@oinak

Although, it's not what I usually do, I totally believe in good semantics.

If I manage to do tomorrow's assignments quickly ("if", because it very well might be a toughy), I shall try to make something readable.

@mina you know Larry Wall is going to put you on the "naughty" list, right? 😈

@oinak

I know that very well.

BTW: I learned Turbo Modula in uni in the late 80s.

@mina I learned TurboPascal! I wonder if there is a rule forcing universities to teach you something called /Turbo.*/ ?

@oinak

It was all the rage of the time.

Remember the "turbo" button on PCs?

@mina yes I am that old, my first "program" (DOS batch) was written on this https://en.wikipedia.org/wiki/PC1512

@oinak

We must be roughly the same age.

My first "real" computer (after the ZX81) was a 286 AT, slightly more powerful than your machine.
