Since this is xkcd, can someone check whether this 15 puzzle is solvable? I seem to recall that 1/2 of possible permutations fail. And this is the sort of Easter egg we have come to expect from our lord and master Randall Cyclic3 (talk) 13:51, 15 May 2019 (UTC)
- Unfortunately, it’s unsolvable.
- If the 15-puzzle is laid out like a numpad with 1 in the bottom left and the hole in the top right it is solvable. 126.96.36.199 14:23, 15 May 2019 (UTC)
- Really? I got it on my fifteen puzzle.
- It's also possible to do if you just put the blank in the upper left corner, so _123,4567,etc. Source: I just Googled and downloaded a solver with a very annoying input method (Why can't I just type the numbers?) Trlkly (talk) 21:06, 15 May 2019 (UTC)
"Key travel" is the vertical distance a key moves when you press it. "Unlimited key travel" would make it very hard for it to register that a key has been pressed.188.8.131.52 14:03, 15 May 2019 (UTC)
- Perhaps the XKCD Company has partnered with ExampleName.Website.
- Doesn't "unlimited key travel" mean that the key will fall out from keyboard and get lost? -- Hkmaly (talk) 22:51, 15 May 2019 (UTC)
- You probably have the Substitutions filter on your computer and forgot about it. (I do too, it's great.) It's XKeyboarCD, and the capital letters spell XKCD (for if that wasn't obvious). 184.108.40.206 14:10, 15 May 2019 (UTC)
What are the supposedly 5 most useful emoji? I recognize the laughing/crying one on position two and an Octopus on position three. 220.127.116.11 14:35, 15 May 2019 (UTC)
- I think it's 'racehorse' & 'beer'. nachuo (talk) 14:44, 15 May 2019 (UTC)
- The last one is 'aerial tramway'
A friend of mine loves Rubik's Cubes, so I immediately went looking for a Rubik's Cube shaped keyboard... Instead I found Rubik's Cubes with keys glued to them, but they aren't functional. Anyone know of a cube-shaped keyboard? A 3x3 is enough for letters, numbers, & most common punctuation; a 4x4 could include most important keys found on a regular QWERTY keyboard. Surely this is already a thing? I was ready to say "Shut up and take my money!" ProphetZarquon (talk) 15:20, 15 May 2019 (UTC)
- The closest thing I can find is the Twiddler or the DecaTxt. 18.104.22.168 16:24, 15 May 2019 (UTC)
- Because of all of the moving parts in a functional Rubik's Cube, a working keyboard would have to have several separate wireless components, which might get expensive fast. I agree that it should be possible, but I don't think we should expect to see it in mass-production in the next five years or so. That said, someone might find an ingenious way to combine existing technologies into a similar product. 22.214.171.124 01:25, 16 May 2019 (UTC)
- The directional arrow key would be the existing production Lenovo's red Track Point button.  So this is close to a "real" button.
Confirmed that the numeric pad cannot be put into numerical order without removing keys and placing them in another order. There are 28 keys on the top row which usually is the function key row. Also the Ergonomic keyboard would cause serious physical and mental pain to everyone. Punchcard (talk) 22:32, 15 May 2019 (UTC)
I wonder why the galaxy emoji from https://xkcd.com/2131/ isn't shown as one of the "5 most useful emoji"?
In what dialect of English do the words “bird” and “turn” share a vowel sound? I asked three of my friends to say both words and we all pronounce the vowel sound differently (I mean, “bird” differently from “turn”; we all pronounced the individual word “bird” the same, and “turn” the same). The words “bird” and “tern” on the other hand, do seem to have the same vowel sound.126.96.36.199 03:27, 16 May 2019 (UTC)
