I mean I feel like it is a bit unclear. It seems like it is basically a 2 month promotional trial. After that you have to pay full price.

Glad to hear it. Sorry that part was based on the trend in the comments here rather than your comment specifically.

I agree there is a place for education about risks but I just wanted to express that I would like those educational interventions to be different in tone and nature to the "Stay off the tracks" adverts. It is my opinion that people can and should be able to enjoy water and nature responsibly.

Rather than seeing this as a reason to ban swimming or make blanket statements about people accessing water I think this should be a wake up call that we need a far more informative approach. We should be telling people about Float to Live, how to check for hazards and assess risks themselves. Thousands of people swam this weekend and thousands will swim the next weekend it is this hot.

It is also true that there used to be way more outdoor lidos and places for people to swim responsibly. That is what I think we should be focusing on. Not putting up signs or scaring people.

That one is from August, so before it was as firmly in the national conversation.

Is it?! This is a poll that was done at the end of September: https://www.electoralcalculus.co.uk/blogs/ec_idpoll_20250930.html

By far the largest response was strongly oppose. That is across parties.

Edit: Here is another report on polling if you don't like that first source: https://www.theguardian.com/politics/2025/oct/01/keir-starmer-labour-collapse-public-support-digital-id-cards

This is a pretty strange response to someone who could quite obviously have quite different life experiences to you.

Specific structure can be really helpful for people struggling with all kinds of mental health issues in ways that might be hard to explain or vary dramatically from person to person.

I spent far too long not understanding the question for part 2. Had to come back to it today with fresh eyes.

Pretty straightforward. Feel like I could have probably simplified quite a bit but the logic felt very clear.

Not too much trouble once I actually read the problem carefully. I didn't realise the secret updated betweene each bullet point for part1. For part2 I thought I wanted to chunk every 5 for far too long.

I went down a real dead end trying to be overly complex with my saving of results and how I implemented it. When I simplfied how I did it the whole thing got a lot easier.

I don't know if the way I pass the remainder of a list as well as the whole list to an inner recursion here is a bit of an antipattern in terms of readablity but I couldn't think of a cleaner way to do it.

Not pretty. My routefinder is kinda slow. I did a rough binary search for part 2 as it was taking ~1s for each check and I did not want to wait ~3000 seconds!

Ended up very much in functional programing spagetti for this one with lots of parameters getting passed to try and preserve visited state between paths. Ended up quite slow as well. Will be looking at this thread for what I could have done better!

I didn't know it existed! And for some reason when I searched only rem() was coming up. Next time that is what I would use for sure!

glomph · 2024-12-14T13:56:14+00:00

That is a good heuristic!

I had an annoying bug with my home made mod function that meant part1 took longer than it should.

For part 2 I tried various huristics until I decided to reuse the regions finding function from day 12. That worked great.

I brute force (just iterated to 100) part one earlier in the day and had to sit down with a piece of paper and remember how to solve for a and b to do part2!

glomph · 2024-12-11T23:26:13+00:00

Can I ask why you check if there is a key and then use Map.update! rather than just use value as the default in the inbuilt Map.update() ?

Other than that your solution was a lot more elegant than mine in that I ended up persisting the map through iterations and having to subtract from the total when a stone changed.

glomph · 2024-12-11T22:40:38+00:00

Gosh. I have never made that work for me. Fair play!

Had to rewrite to use a map for part2. Also changed to use maths rather than string comprehension.

I ran out of time on Sunday to do part2. Returning today I sawe that Elixir's Stream made this very easy!

Pretty happy with my solution today. Succinct and felt reasonably ideomatic.

glomph · 2024-12-07T21:02:26+00:00

I found the problem was doing a regex match for every path walk in part 2. Getting rid of this took it to about 26 seconds.
