So thanks to Luna_blade, we know this started recently... anyone else interested.... ? http://adventofcode.com

Spoiler for My answer (in Python code) to the first part of the Day 1 problem (So don't look until you solve. But the main point is to show that it's short.):
myInput = "R4, R3, L3, L2, L1, R1, L1, R2, R3, L5, L5, R4, L4, R2, R4, L3, R3, L3, R3, R4, R2, L1, R2, L3, L2, L1, R3, R5, L1, L4, R2, L4, R3, R1, R2, L5, R2, L189, R5, L5, R52, R3, L1, R4, R5, R1, R4, L1, L3, R2, L2, L3, R4, R3, L2, L5, R4, R5, L2, R2, L1, L3, R3, L4, R4, R5, L1, L1, R3, L5, L2, R76, R2, R2, L1, L3, R189, L3, L4, L1, L3, R5, R4, L1, R1, L1, L1, R2, L4, R2, L5, L5, L5, R2, L4, L5, R4, R4, R5, L5, R3, L1, L3, L1, L1, L3, L4, R5, L3, R5, R3, R3, L5, L5, R3, R4, L3, R3, R1, R3, R2, R2, L1, R1, L3, L3, L3, L1, R2, L1, R4, R4, L1, L1, R3, R3, R4, R1, L5, L2, R2, R3, R2, L3, R4, L5, R1, R4, R5, R4, L4, R1, L3, R1, R3, L2, L3, R1, L2, R3, L3, L1, L3, R4, L4, L5, R3, R5, R4, R1, L2, R3, R5, L5, L4, L1, L1"

c = [ 0,  0,  0,  0]
d = 0 #Direction facing
for b in myInput.split(", "):
    d += {"L": 1, "R": -1}[b[0]]
    c[d&3] += int(b[1:])

print c #c[0], c[1], c[2], c[3]
print c[0] - c[2] + c[1] - c[3] #Remove the sign.

#Extra:
print d #Difference between L and R turns.

Edit: Replaced if block with dictionary check, and swapped regex with the more simplified.

Do you write super short Python, or is it naturely this short?

Um? Both? Well, it depends on the coder... ( For example, someone who divides things up might code like https://github.com/jldork/Advent_04/blob/master/room.py , but that's a spoiler for today's AOC. ... And yeah, I looked on reddit to see what everyone's talking about. :) )

Someone else also tried Day 1, and their code was a bit longer than mine... They had written out if blocks for the caps, where-as I just &3.

My Part 2 for the Day 1 challenge was a bit longer than Part 1 as well... I didn't look into much optimizations.

Spoiler for Hidden:
import re
a = "R4, R3, L3, L2, L1, R1, L1, R2, R3, L5, L5, R4, L4, R2, R4, L3, R3, L3, R3, R4, R2, L1, R2, L3, L2, L1, R3, R5, L1, L4, R2, L4, R3, R1, R2, L5, R2, L189, R5, L5, R52, R3, L1, R4, R5, R1, R4, L1, L3, R2, L2, L3, R4, R3, L2, L5, R4, R5, L2, R2, L1, L3, R3, L4, R4, R5, L1, L1, R3, L5, L2, R76, R2, R2, L1, L3, R189, L3, L4, L1, L3, R5, R4, L1, R1, L1, L1, R2, L4, R2, L5, L5, L5, R2, L4, L5, R4, R4, R5, L5, R3, L1, L3, L1, L1, L3, L4, R5, L3, R5, R3, R3, L5, L5, R3, R4, L3, R3, R1, R3, R2, R2, L1, R1, L3, L3, L3, L1, R2, L1, R4, R4, L1, L1, R3, R3, R4, R1, L5, L2, R2, R3, R2, L3, R4, L5, R1, R4, R5, R4, L4, R1, L3, R1, R3, L2, L3, R1, L2, R3, L3, L1, L3, R4, L4, L5, R3, R5, R4, R1, L2, R3, R5, L5, L4, L1, L1"
wordList = re.sub("[^\w]", " ",  a).split()

#Part 2
d = 0
mxy =
  • * 1000000 #Random-ish number. But array-size.
x = 0
y = 0
for b in wordList:
    if b[0] == 'R':
        d -= 1
    if b[0] == 'L':
        d += 1
    d = d & 3
    i = int(b[1:])
    while i > 0:
        if mxy[y*1000+x] == 1:
            print x, y
            break
        mxy[y*1000+x] = 1
        if d == 0:
            y += 1
        elif d == 1:
            x += 1
        elif d == 2:
            y -= 1
        elif d == 3:
            x -= 1
        i -= 1
I think the forum BBCode stuff is messing up something. :/ Don't mess with my
  • , forum!

I don't know all the Python tricks yet, but it is possible it could be even shorter than that.
Like the L and R checks:
- Not sure if Python has a ? : operator.
- Could probably use a dictionary type.

AZVRE: Im pretty okay, what about you?
Yesterday at 01:17:14 AM
Fox: I think the nine is doing a cirno on me, though... Anyway, how is everyone doing today?
Yesterday at 01:12:20 AM
Fox: onesixtwo*
Yesterday at 01:12:00 AM
Fox: Okay... Meanwhile... ah... 162 being a number that has made itself known to me.... I look at the relationships of the numbers.... 162  1+6+2 = 9 ; onesizetwo = alphabetical order = 9 characters ; Distance apart analysis: os = 4 = 1[6][2] , st = 1 = [1]6[2] , ot = 5 = [1][6]2 ; ost = original sound track?
October 15, 2017, 06:31:17 PM
AZVRE: ah okay :D i thought i caused some trouble
October 14, 2017, 07:49:16 AM
Fox: Oh i know... You were messing with yours, and the description says mine. It's kind of a funny bug. :P
October 13, 2017, 08:18:31 PM
AZVRE: I did not edit your profile tho. Just to erase that confusion ^^"
October 12, 2017, 04:49:56 AM
Fox: e.g. this art = http://forum.goldensunhacking.net/Themes/Jupiter/images/catbg.gif (etc.)
October 12, 2017, 04:48:58 AM
Fox: I have a question: Where did the art for the headers come from? (Like the backgrounds to each of these things... "Affiliates", etc... Asking just incase it inspires me to do something... but if Charon made it, then that's cool too.
October 11, 2017, 04:23:02 AM
FoxWas thinking about having something for the editor anniversary, but I believe I had to change my mind....
October 10, 2017, 12:58:36 PM
Fox: That's alright. ;       @AZVRE's profile: "Current Activity:  Editing the profile of Fox." ...Eh... That looks weird.
October 07, 2017, 11:45:16 PM
Atrius: Sorry about that, the auto bot detection is still working, but it also requires an admin to visit the site regularly.
October 04, 2017, 04:17:40 AM
Fox: Yeah, it does bring a small amount of activity. Not good quality activity, but it's still activity, nonetheless.  Now if we can get them to randomly post pictures and vdeios!
October 04, 2017, 02:10:48 AM
Majora: If nothing else, I like how they're copying the content of real posts at random. Interesting to see how they adapt to seem more authentic
October 03, 2017, 08:29:38 PM
Fox: medico6601 = Most likely another bot. :(
September 26, 2017, 03:32:24 PM
Fox: by ten* Excuse me.
September 26, 2017, 03:32:12 PM
Fox: Oh yes... Also multiply all levels by two. (So actually, an adept will have levels of 54, 3, 2, and 1, rather than 5, 0, 0, 0.... if going by those.)
September 26, 2017, 03:29:07 PM
Fox: ...I mean the theory also saves space on the Status Screen.
September 26, 2017, 03:26:11 PM
Fox: Random/fun concept theory: What if we got rid of ePow/eRest, and just made eLevel do everything. :P (A process of cleaning stuff up... Though, could make things less versatile. - Like, if a Djinni add 1 eLevel = Okay, that's understood... by why specifically +5 on the ePow/eRes (Rhetorical))
September 23, 2017, 04:42:08 AM
Fox: Oh nevermind, it does... but I swear I saw that a minute ago.
