The "etc" is pretty important here. You can log in using Reddit, and you can create a random throwaway Reddit account without filling in any other details (no email address or phone number required).

I believe they no longer allow new accounts without an email address. It used to be that reddit had a user creation screen that looked like you needed to input an email address, but you could actually just click "Next" to skip it. The last time I had cause to make a reddit account, they no longer allowed this.

You can use a garbage email address, you don't have to verify it

Got to agree. I'm even surprised at just how little progress many of my friends and ex-colleagues over the years make given that they hold down reasonable developer jobs.

My experience has been "little progress" is related to the fact that, while AoC is insanely fun, it always occurs during a time of year when I have the least free time. Maybe when I was in college (if AoC had existed back then) I could have kept pace, but if part of your life is also running a household, then between wrapping up projects for work, finalizing various commitments I want wrapped up for the year, getting…

Yep, the years I've made it the furthest have been around the 11-12 day mark. The inevitably life and kids and work get in the way and that's it for another year. Changing to a 12 day format is unlikely to affect me at all :)

Excited to see AOC back and I think it was a solid idea to get rid of the global leaderboard. We (Depot) are sponsoring this year and have a private leaderboard [0]. We’re donating $1k/each for the top five finishers to a charity of their choice. [0] https://depot.dev/events/advent-of-code-2025

i don't think it should be a charity of their choice. i think it should have to be one of the top 5 most reputable charities in the world, like doctors without borders or salvation army.

It was pretty boring trying to place against aggressive AI pipelines like yours throughout the explicit requests not to use them[1]. I’m sorry to hear it became boring for you too. [1] https://web.archive.org/web/20241201070128/https://adventofc...

I mean, everyone else was using them too, how can you not? That was the name of the game if you wanted to be competitive in 2024. Not using them would be like trying to do competitive pro cycling without steroids, basically impossible.

i felt like that 2-3 months ago, at the east new zealand chess games, when i forgot my anal beads.

It's just bluffing, lying. People lie to make others think they're hot shit. It's like the guy in school who gets straight A's and says he never studies. Yeah I'll bet.

They... sort of are though? A year or two ago I just waited until the very last problem, which was min-cut. Anybody with a computer science education who has seen the prompt Proof. before should be able to tackle this one with some effort, guidance, and/or sufficient time. There are algorithms that don't even require all the high-falutin graph theory. I don't mean to say my solution was good, nor was it performant in…

You say in your comment: "Anybody with a computer science education ... should be able to tackle this one" which is directly opposed to what they advertise: "You don't need a computer science background to participate"

I made my own, with a Haskell+Bash flavor and a REPL that reloads with each keystroke: https://www.youtube.com/watch?v=r99-nzGDapg This year I've been working on a bytecode compiler for it, which has been a nice challenge. :) When I want to get on the leaderboard, though, I use Go. I definitely felt a bit handicapped by the extra typing and lack of 'import solution' (compared to Python), but with an ever-growing 'uti…

>I made my own, with a Haskell+Bash flavor and a REPL that reloads with each keystroke That was impressive! Do you have a public repo with your language, anywhere?

yep, https://github.com/lukechampine/slouch. Fair warning, it's some of the messiest code I've ever written (or at least, posted online). Hoping to clean it up a bit once the bytecode stuff is production-ready.

That’s also completely true and something I often say about gaming. You don’t like achievements? Just don’t do them. Your enjoyment shouldn’t be a function of how others interact with the product.

"Just ignore it" doesn't work, psychologically.

I stopped staying up until midnight for the new problem set to be released and instead would do them in the afternoon. Even though I could compare my time to the leaderboard, simply not having the possibility of being on the board removed most of the comparison anxiety.
