Who flagged Calvin's question as "unclear"?
 
To be honest, it is a bit unclear, though mostly in the sense that it takes a bit of time to figure out exactly what's going on.
@Sp3000: Fixed it.
 
@El'endiaStarman ^_____^
 
Haha, it was amusing to see that in your challenge. :P
 
wow 57 chatters!
@phase How can someone go through you? I think only Flash can do that (or ghosts) and both are likely fictional.
 
Fun fact: N = 31 and digit string 038 is a fixed point.
 
9:09 AM
@El'endiaStarman f=lambda D,N,i=0:D[i:]and str(sum(map(int,(D*N)[(i-N//2)%len(D):][:N]))%10)+f(D,N,i+1) <-- lot shorter in Python 2, but shrugs
 
Figures. :P
Wait, I don't see any Python-2-only bits in there. Lemme try it.
 
That's cos I ported from what I had :P
 
I got this: TypeError: 'int' object is not subscriptable.
Oh, you changed the order of D and N.
Shame on you!
Other than that, works perfectly. :P
 
Er... yeah my test cases were the other way around
 
That was only -6 bytes. :P

@El'endiaStarman There's a difference between "this is unclear" and "I didn't spend the time reading this to understand it"

9:56 AM
@Sp3000 @El'endiaStarman there's a trick I learned from Sp3000 that I think is useful for the automata quetion: sum(map(int,s))%10 can be done as int(s,11)%10, for the same reason that in base 10, the values of a number mod 9 equals the sum of its digits mod 9
 
that's very nice ^
 
Oh that's what it was, I was trying to remember that but forgot how to apply it :P
Yep, 80 for Py 3, 75 for Py 2

i have never done a really long golf, so i'm not sure, but i'm skeptical
i'm getting issues in the Python 2 version of automata with L's
 
Hmm yeah, not sure how long a long golf would need to be for that to help, if at all..
 
i feel like even long golfs rarely use that many different built-ins, so it would be shorter to save them all to vars
 
(Oh... it does give an L, darn)
Yeah that's true as well
79 for Py 2 I guess then? Unless it's fixable somehow

Q: Opening program on commandline in new terminal with new profile

Mathias Jacob SchreinerI'm using OSX Yosemite and the built in Terminal on my mac. I have quite a few terminal windows running most of the time and it's hard to navigate around in all of them as they all look alike. So what I want to do is run my commands as usual, but in a new terminal window with a chosen profile. ...

 
Design question: I have an idea for a live-action KotH. I want to send regular (fast) map/position updates to each player, but give them more than one frame's worth of time to process each (and not require an action/response for each frame). I'm worried about spawning a bajillion threads for this, though, and am looking for some way to do this smoothly. Ideas?

Can you give some more details?
 
Yes, I'm trying not to give away the exact game until it's more complete, but let me think...
I need the controller to asynchronously accept input from the players, while feeding them info the whole time. Basically how an online client/server model might work for a shooter or MMO, but I'm hoping not to have to go that far.
Hmm. Actually, I think I have something figured out. Maybe. Thanks, rubber duck/penguin.

see what you do is you spawn a new process for each client, and have each process spawn a new thread for every input, but make sure not to kill any threads in case you need them later /s

The first season was alright. It felt like another "oh crap we're superheroes now" show. The second season was what would make or break it, and it broke it.

The second season being not as good, that is.
