I've completed "Secret Entrance" - Day 1 - Advent of Code 2025 #AdventOfCode
Last year, I tried to go hard on modern C++ and ranges/views.
This year, Rust! This is a learning exercise for me, so I'm guessing my code is far from idiomatic....

After 30+ years of daily driving manual transmission cars, we're now an all-electric family.
End of an era for sure. Bitter sweet....

During #AdventOfCode 2024, I dove deeper into #C++ ranges and views. Here's some of what I learned:

Bubble sort in C++23?!???
I made an "nm_pairs" view during #AdventOfCode, largely as a tool to better understand what it takes to make a custom view in #C++.

Make your #AdventOfCode problem twice as fast with this one weird trick ...
I was absolutely sure the compiler (clang-18) would do this for me, but alas, it didn't.... Went from ~40ms to ~20ms.
Hat tip to @49pctber.bsky.social
I peeked at their code and was like "nah, THAT can't be it..."

Finally figured out how to make my "Utils::views::nm" play nicely with C++23 ranges/views.
This makes the final #AdventOfCode problem super nice in C++!
I need to do a proper write-up on both the AoC problem, as well as the difficulties of making a C++23 custom view....

@daveeddy.com tiny tip of the day based on your (awesome) day 16 video:
wc -l -> Get number of lines in a file (you did that)
wc -L -> Gets longest line in the file ;)
So, grid size for day 16 -> wc -lL

I've completed "Code Chronicle" - Day 25 - Advent of Code 2024 #AdventOfCode
Man, if I could just turn my mn_const_view() into an actual view, this would actually have been a "one liner" in C++ :)
Thank you, AoC team and participants!
Merry x-mas and happy holidays!!!!!!

Day 22 was an absolute breeze and a blast, after 21 was a thorough kick in the pants for me... Both done now and officially caught up!
Always fun to use fold_left() weirdly :)
Hopefully, no more hard ones 'til x-mas :D

After finishing Day 17 four days ago, I went back and actually implemented a JIT compiler that reads the program from file and emits x86_64 assembly :D
Works for the quine, sample and my input and is blazingly fast!
TOTAL overkill but fun learning!!

And a fun little "Quine detector" for part 2.
Great puzzle today! I needed that after 16..

Went back and optimized "Day 7 - Bridge Repair" by writing my own concatenate operator. It's not that I am smarter than std::format, it's just that I have a much smaller problem space :D
All 13 days so far now execute in ~200ms, running sample AND final input calculations.
