I was going to say "Yea, you're right. I problem am too lazy to go check anyway." but then I realized that the gas station I go to has a machine that will scan your barcode and tell you if you won or not.
Print Euler's number on its own graph
code-golf
Print the first n characters of Euler's number (e, 2.718281828459...) on a 'graph' of e^n. For example, input 3 (the x and y-axis scales here are provided for reference, and need not be implemented in your program):

@Calvin'sHobbies The newest comment it's showing me is from 9 minutes ago. I guess I have to wait for YouTube to have a cup of coffee before it can show me the comments.
I'm building a giant lego robot and I need to generate some particular gear ratios using a set of gears. I have lots of gears with the common lego gear sizes: 8, 16, 24, or 40 teeth. Write a program I can use where I input a gearing ratio and the program tells me what combination of gears I sho...

Help! I accidentally dropped my TI-84 calculator out my window (don't ask how) and it broke. I have a math test tomorrow and the only calculator I can find is one with these buttons:
7 8 9 +
4 5 6 -
1 2 3 *
0 = /
My math test is a review test on evaluating expressions. I need a...
@MartinBüttner It's a good place to save drafts of posts until the poster thinks they're ready. Question drafts are not always saved properly and using an external markdown editor is a hassle.
@MartinBüttner I don't have in depth knowledge of CAs but from how universal they can be, I'm guessing that with some work you could convert whatever polyomino changes you settle on using into an equivalent CA. Lack of knowledge prevents me giving even the suggestion of a proof for that though...
You have chosen the categories for PPCG's first ever "Best of". We have decided in chat to stick to the top 7 categories, because using any more will probably divide people's attention too much. We've also decided to separate nominations from actual voting to avoid the FGITW effect.
So here is w...

Haha. Guy1 asks who is printing gibberish to the back printer. Guy2 sends a private response. Guy1 adds everyone back and says "Thanks all, we figured out who was printing."
I'm going to nominate a fortnightly challenge for labor of love. If it was intended to be a one author->one challenge kind of category, then it just won't win that nomination.
It never got as much attention, unfortunately, although I feel like CH put more effort into that one. I'll check the chat logs to confirm when I write the description though
@AlexA. It wasn't as good as a game as RvB. I had envisioned more actual building with the blocks but most submissions just moved blocks around with the bots, making the whole block part kind of unimportant.
@trichoplax Sorry, totally forgot about that message. Well, since some CAs are TC, some form of conversion is bound to be possible, but I'm not sure how much it will actually resemble the structure of the kind of system I'm suggesting. You can't just encode the shapes in states for instance, because the changing states also mean that adjacencies change over time, which isn't possible in classical CAs.
@trichoplax they could change yes, but I was thinking that a conversion would actually encode each of the compound cells in my system as a single cell in a classical CA
Rookie of the Year (challenge)
Best challenge by a user who had not posted a challenge before 2015.

This is one of the coolest chalenges that I've seen on the site. It encouraged users to think o...
@ZachGates one thing you might mention about the versatile integer printer is that the score was ridiculously well-balanced for a combined score. (it was probably more luck than anything else, but it's part of what made the challenge as fun as it was)

One night, I was just contemplating on numbers. I found out about something unique about numbers like 7, 10, 12, 13, and more. They are squares of squares! Meaning, that when squared, are comprised of squares themselves. The OEIS calls them Squares which are a decimal concatenation of tw...

I'm kinda new to this whole "reviewing" thing but I understand the basics of what to do and what not to do, so I clicked "Recommend Deletion."
