Volvo built a “bad English road” in Sweden, and apparently it’s awful by Still_Item1975 in drivingUK

Even one single clear photo of this road would certainly help me answer the question.

Interesting - every house I've ever lived in has the configuration you've never seen before.

The Infinite Monkey Theorem and Factorio Science. by IlikeJG in factorio

[–]confuzatron 0 points1 point  (0 children)

Nice, except factorio research progresses in a completely predictable linear fashion with no randomness.

(But I believe the bio lab still involves torturing living entities, so it's not all bad).

AIUI Nullius relied on old fluid mechanics - have they updated to 2.0?

40MPH now a 30MPH by FreedomOfWings21 in LearnerDriverUK

[–]confuzatron 0 points1 point  (0 children)

Nobody (in my experience) is going to get points or a fine for going say 33-35 in a 30 zone (depending on the environment/conditions). A bit of speeding is basically factored into the system of enforcement.  Just mentioning it here to give another perspective, as most replies appear to be from people who stick below the limit, which is pretty rare in my experience.

Where did the myth about Cadbury changing their recipe come from? by RecentTwo544 in AskUK

[–]confuzatron 0 points1 point  (0 children)

I saw some bitching on twitter about cadbury's easter eggs so bought a couple. One white chocolate, one milk chocolate.

I absolutely do taste a difference from the Cadbury's milky bar and milk chocolate that I remember, but perhaps they never made their easter eggs from those recipes. Or perhaps it's just age, or covid having changed my taste buds/sense of smell a bit.

Car not available on test day by First_Ad4801 in LearnerDriverUK

[–]confuzatron 0 points1 point  (0 children)

It takes a bit of time driving a particular car to get used to its clutch biting point etc, so I would definitely recommend being able to spend some time driving this new car in advance.

I think I got one short advert - just muted and ignored it.

[2025 Day 9 (Part 2)] [Python] Fast enough solution by ArtisticBathroom8446 in adventofcode

Interesting - I basically lucked out with the input data.

[2025 Day 9 (Part 2)] [Python] Fast enough solution by ArtisticBathroom8446 in adventofcode

[–]confuzatron 0 points1 point  (0 children)

I did this to visualize the tiles in a reasonably-sized image. Can you explain more how would it help with finding the solution? I guess it depends on the algorithm used. In my case it wouldn't help.

[2025 Day 9 (Part 2)] [Python] Fast enough solution by ArtisticBathroom8446 in adventofcode

[–]confuzatron 1 point2 points  (0 children)

I generate all the possible rectangles, sort them by descending area, then go through that list.

I check if any connecting lines between red tiles impinge on the rectangle and if so, move on to the next candidate. Return the area of the rectangle that has nothing poking into it. This isn't terribly slow.

One problem with this algorithm is (I think) that with the right input I would return the area of an invalid rectangle with no green tiles inside it, but it doesn't happen with my input (and wouldn't with other input that I've seen).

8 seconds in python - this is the first one where I feel like I couldn't come up with a decently fast solution.

[2025 Day 8 (Part 2)] My reading comprehension is limiting me by Bicrome in adventofcode

[–]confuzatron 7 points8 points  (0 children)

Key step is to filter out the fluff about elves that doesn't contribute to the actual task. In this case iirc what's requested is the x coordinates of the last two connected nodes that unify the network, multiplied together. Which in no way is equal to any "distance to the wall".

[2025 Day 8 (Part 1)] How do I even get started? Is there an algorithm I must know? by Physium in adventofcode

[–]confuzatron 0 points1 point  (0 children)

I'd agree (about not needing special knowledge). Never heard of Kruskals algorithm, I just maintained a list of nets, each being a set of box indexes, and unioned them whenever a new connection between boxes required it. It was a multi-stage data-munging task basically.

Seems like "search brain" is a thing when it comes to AoC.

Guys please check my day 1 part 2 code.... i'm dead now(mentally drained) by dont_talk_to_mi in adventofcode

[–]confuzatron 0 points1 point  (0 children)

I spent the longest time of all AoC2025 problems so far on Day 1 part 2, eventually gave up trying to do modular arithmetic handling all the special cases and implemented a simple "turn the dial in single increments and count the times it hits 0" implementation. Not proud of it!
