If you're doing #AdventOfCode and learning stuff, but your code's a mess, you got the wrong answer, you're a few days behind, it took you several hours, you're in a language you're not familiar with. All I hear is that you're learning stuff. You're doing great!! 🌟❤️🎄🧑🎄.

As an AWS user, I often want to know the cheapest options for compute resources given some project-specific criteria. So, I made a tool to show me that data in a way that is useful to me. Maybe it will be useful to you, too:

Did you know? You can just put a "Do #AdventOfCode" ticket right into your sprint! If anyone asks who approved it, tell them it was me. ❤️. If that doesn't work, just rename it to something like "leverage enrichment synergies for improved engineering efficiency" or something. 📈.

As we get further into the month, remember that it is okay to sleep and come back to #AdventOfCode puzzles, ask for hints, or even skip them entirely. Difficulty varies based on your own experience and background, and if a puzzle is hard, future puzzles might still be doable!.

As you do #AdventOfCode this year, please remember to be kind to each other and to yourself; everyone is at a different place, and things that are easy for some people are hard for others. Focus on improving yourself, and be supportive of others as they try to do the same. 🌟.

I'm already seeing a lot of unnecessary traffic to the #AdventOfCode servers. Please limit private leaderboard requests to once per 15 minutes. Please don't run scripts that scrape the entire site with a burst of requests. IP addresses that flood the servers will be blocked.

If you want to run an #AdventOfCode event for your employees (and you should!), you should run it like my employer, @TCGplayer, does:. Stars can be exchanged for prizes. Due in January. Bonus points for newbies or new languages. Speed is irrelevant.
