 And now, for the grand finale... Day 25! [ goto ]Think you know code? Want internet points on a leaderboard? Check out Advent of Code! quote:Advent of Code is a series of small programming puzzles for a variety of skill levels. They are self-contained and are just as appropriate for an expert who wants to stay sharp as they are for a beginner who is just learning to code. Each puzzle calls upon different skills and has two parts that build on a theme. My buddy who created this crazy thing is equal parts genius and madman, and now he's sharing his insanity with you. Whether you're looking for an excuse to learn a new language or brush up on a rarely-used language (or stick to your tried-and-true), the Advent of Code will give you a run for your money. So, let's get this Advent party started. Every midnight I'll (try to remember to) post the daily challenge summary. It's up to you to make 'em go! --- Day 1: Not Quite Lisp --- quote:Santa was hoping for a white Christmas, but his weather machine's "snow" function is powered by stars, and he's fresh out! To save Christmas, he needs you to collect fifty stars by December 25th. daggerdragon fucked around with this message at 06:03 on Dec 25, 2015 |

--- Day 2: I Was Told There Would Be No Math ---quote:The elves are running low on wrapping paper, and so they need to submit an order for more. They have a list of the dimensions (length l, width w, and height h) of each present, and only want to order exactly as much as they need.

--- Day 3: Perfectly Spherical Houses in a Vacuum ---quote:Santa is delivering presents to an infinite two-dimensional grid of houses. [...] However, the elf back at the north pole has had a little too much eggnog, and so his directions are a little off, and Santa ends up visiting some houses more than once. How many houses receive at least one present?

Ephphatha posted:I didn't feel that dirty doing it that way, my slow rear end perl script took less than a second to do part 1 and about 3 seconds to do part 2. Only crashed my terminal once when I called the script with no input and triggered a warning on every iteration... This string parsing challenge was pretty simple to do with perls regex engine as well. My buddy is not willing to screw with the logins while the Advent is running since we're trying to make sure that the server (and code) stay stable for the entire duration of the Advent. However, you can create another account using your Github profile, re-use your existing code (you did save it, right?) to solve up to today's puzzle, and only use that one to solve future puzzles from now on if you want to try to make it on the leaderboard.

LOOK I AM A TURTLE posted:I found Day 8 to be simpler in comparison. We've noticed that Day 8 was polarizing in that players either immediately understood and knew how to solve it (like you) or had absolutely no clue where to even start. It's fascinating.

Xarn posted:Why is the site down just as I decided to procrastinate and code? Ah, sorry about that, I should have put a notice up this morning when the datacenter lost power >_< We were only out for like, 45 minutes. I'm just glad it happened at 10am and not near midnight :/ "Your server is offline" = worst alarm clock ever.

Volguus posted:What I hope is that in January we would get the really nice and elegant solutions to all these problems which would put my brute-forced crap to shame. There aren't that many clean and elegant solutions, if the solution megathreads in the subreddit are any indication. Most people are just coding as fast and as sloppily as they can in order to hit the leaderboard, and half as many are taking the easy way out with libraries like itertools. Ah well.

Spraynard Kruger posted:Man, it really feels like the difficulty in these has ramped up lately, and yet, the top 100 on the leaderboard seem to always be half hour or less solves. I'm still stuck on finding algorithms for days 19 and 20 that can run in a reasonable amount of time. Oh no, sir. Day 19 took drat near 4 hours just to cap the leaderboard at 100 gold. I had to go to work at 9am. :/ Good luck!
