Something is wrong with global snow production, and you've been selected to take a look. The Elves have even given you a map; on it, they've used stars to mark the top fifty locations that are likely to be advent of code reddit problems. You've been doing this long enough to know that to restore snow operations, you need to check all fifty stars by December 25th.

Advent of Code is an excellent annual collection of programming puzzles. It's quickly become my favorite part of the holiday season as a celebration of programming: carefully crafted puzzles, amazing solutions spanning astonishing technical stacks, beautiful visualizations — with a sense of humor and joy around it all. The reason I recommend AoC strongly is because it's simply so much fun : there's a surreal and light-hearted Santa-themed story wound around each year's story, an amazing — and inspiring — community on Reddit ; and the puzzles are generally aimed towards teaching something new. I'd strongly recommend it even if you don't generally enjoy programming competitions like Code Jam or Hacker Cup. Very briefly: a new puzzle unlocks every night at midnight, Eastern time from 1st to 25th December. Each puzzle has 2 parts, with the 2nd part generally being a more complex variation on the theme. Inputs vary and can be large; occasionally involve ASCII art or other sentences that need to be parsed.

This is particularly valuable when exploring solutions from excellent programmers like Peter Norvig. Awesome Advent of Code : a massive collection of tools, templates and solutions.

You're already almost 1. What you can see, however, is a giant squid that has attached itself to the outside of your submarine. Maybe it wants to play bingo? Bingo is played on a set of boards each consisting of a 5x5 grid of numbers. Numbers are chosen at random, and the chosen number is marked on all boards on which it appears. Numbers may not appear on all boards. If all numbers in any row or any column of a board are marked, that board wins. Diagonals don't count. The submarine has a bingo subsystem to help passengers currently, you and the giant squid pass the time.

One Elf has the important job of loading all of the rucksacks with supplies for the jungle journey. Unfortunately, that Elf didn't quite follow the packing instructions, and so a few items now need to be rearranged. Each rucksack has two large compartments. All items of a given type are meant to go into exactly one of the two compartments. The Elf that did the packing failed to follow this rule for exactly one item type per rucksack. The Elves have made a list of all of the items currently in each rucksack your puzzle input , but they need your help finding the errors.

Partial screen recordings: Peek Peek was really useful in capturing a rough sea full of sea monsters: I suspect I'll be using it a lot more frequently at and away from work to capture snippets from my screen. Collect stars by solving puzzles. There's also a significant amount of effort in making sure we don't DDOS the website. It's quickly become my favorite part of the holiday season as a celebration of programming: carefully crafted puzzles, amazing solutions spanning astonishing technical stacks, beautiful visualizations — with a sense of humor and joy around it all. Eric Wastl clearly crafts the problems with a lot of thought and care: which is evident in how clearly the problems are defined, with useful edge cases, and each round is beta tested be we get our grubby hands on it. Writing about them — perhaps as notes in your code repo, tweets, blog posts, perhaps even a Substack if you're with the zeitgeist and an extrovert, or a Zettelkasten if you're an introvert — goes a very long way. Two puzzles will be made available on each day in the Advent calendar; the second puzzle is unlocked when you complete the first. The opportunity to see what others do on the same problem with similar constraints is extremely rare for me: so I really enjoy comparing my solutions with others' and learning from them. Hexagonal grids and indexing Figuring out how to translate hexagonal movement into absolute coordinates was a lot of fun: the key insight to making this all work was realizing that I could represent a single point with several hexagonal paths — and a single set of x, y coordinates. Play to learn As satisfying as leaderboard positions can be, it's much more satisfying to truly learn from Advent of Code: depending on the year and the puzzle, I've improved my knowledge of — and fluency with — graph search algorithms, number theory, learning to choose the right data structure, and — yes — trying to program quickly and failing. Each puzzle has 2 parts, with the 2nd part generally being a more complex variation on the theme. In this example, the calibration values of these four lines are 12 , 38 , 15 , and I spent quite a bit of time revising all I'd learned with Khan Academy.

You may have recently heard some talk about Advent of Code - every developer's favourite advent calendar. In this article, I'm going to try and explain why everyone can get something out of it. Advent of Code is a website that sets daily challenges for each day of advent.

As they're making the final adjustments, they discover that their calibration document your puzzle input has been amended by a very young Elf who was apparently just excited to show off her art skills. Very briefly: a new puzzle unlocks every night at midnight, Eastern time from 1st to 25th December. The newly-improved calibration document consists of lines of text; each line originally contained a specific calibration value that the Elves now need to recover. The unfiltered version of this section is a Twitter thread on my account where I'd annoy my followers and record my victories and failures along the way. Any responses from the server are parsed into markdown and displayed in the terminal — this is particularly useful when the answer's incorrect, and the message from the server includes a hint "Your solution is too low", or "Someone else has this exact solution". This is generally my favorite part of the contest — I can see how other programmers approach exactly the same problem, and learn from them. Vignettes from AoC Spoilers! Instead of looping from In this example, the calibration values of these four lines are 12 , 38 , 15 , and I somewhat annoyingly for any followers tweeted my way through , and regret not keeping a better record for earlier years. Blitzen One part of Advent of Code that I dislike is having to manually save the input files, and then pass them into my solution program somehow. My favorites include: How fortran did operator precedence , described in Wikipedia eval -ing the string in Python after some shenanigans to override operator behavior.
