Writing it up now, parameter for rotation distance.
 
can it be negative?
doesn't matter actually...
 
Not unless you really want me to change it :)
Thoughts? :
> The spiral should be taken as a string, with a line delimiter of your choice (including no delimiter). It will always be a square, not including delimiters.
 
well I don't really care... the current solution unrolls the spiral and defers the rotation to CJam's m> or m< depending on which direction corresponds to positive numbers
@Geobits sounds good. my current solution works for arbitrary rectangles though. (not sure if squares would save anything)
if you want to play around with it (or generate test cases): goo.gl/hXbkhx
 
Thanks :)
Typing them into np++ is a pain.
 
the mistake is clearly that you're using np++ ;) (although I'm not sure it would be that much better with sublime...)

Q: Rotating Spirals

GeobitsGiven a square of text representing a spiral of characters, rotate it! The spiral starts at the center and moves counterclockwise to the outer edge 987 216 345 This translates to the string 123456789. Rotation is done to the left, so if you rotate it one position, it will be 234567891. This i...

 
@MartinBüttner I think the only change yours needs to match spec is reversing the direction of rotation. I had to use negative numbers to do the test cases :)
 
3:36 PM
@Geobits cool, change m> to m< ;)
lol, nice subliminal messages
 
:D
 
you should include another test case where some rotation gives an intelligible sentence/phrase when read by lines
 
I was going to, but couldn't decide on what. Then decided I really only needed two.
I like that the first comes out as words by line, though, even if it was an accident.
 
ah yeah, the restriction to square inputs saves at least 5 bytes

Q: Backward search in UTF-8

anatolygUTF-8 is the most popular encoding for Unicode text.

Ouch. So much violence in the workplace nowadays...
 
Isn't modern life wonderful?
 
@Geobits A test case with an even size might be good, since the last row you traverse is not the top
 
The spec calls for odd sizes only. I did it that way to simplify the meaning of "center" mostly.

Never could understand how that labyrinth was supposed to keep the minotaur in. It's not exactly hard to get out of it.
 
it's a pretty amazing challenge though... I don't even know how best to tackle it
 
Thanks=)
 
Leaning in so you have a lower center of gravity usually helps.

6:07 PM
@Geobits There is a good explanation on how that word developed:
In Greek mythology, the Labyrinth (Greek λαβύρινθος labyrinthos) was an elaborate structure designed and built by the legendary artificer Daedalus for King Minos of Crete at Knossos. Its function was to hold the Minotaur eventually killed by the hero Theseus. Daedalus had so cunningly made the Labyrinth that he could barely escape it after he built it. Although early Cretan coins occasionally exhibit branching (multicursal) patterns, the single-path (unicursal) seven-course "Classical" design without branching or dead ends became associated with the Labyrinth on coins as early as 430 BC, and similar...
 
> It is a confusing path, hard to follow without a thread, but, provided the traverser is not devoured at the midpoint, it leads surely, despite twists and turns, back to the beginning.
Fair enough :)
 
There's nothing better than terrifying the people who live in your house with a screen saver that (looks like an error screen and) says "Something went wrong..."
 
Not original, but still a good one: 1) Take screenshot of desktop 2) Change background to screenshot 3) Move shortcuts into another folder so they aren't visible.
 
@Calvin'sHobbies Nearly halved my original solution!

@Geobits Or rather switch some shortcuts while keeping the same icon.=)
 
6:18 PM
That works too :D
 
@Geobits Just hide icons. Right click on desktop -> View -> uncheck "show desktop icons".
 
One of the quickest is to just set the double-click timer to unusably fast.
@El'endiaStarman I always forget that's there...
 
I used it for a stretch of several months last year so my desktop backgrounds weren't cluttered and I could run whatever I needed from Search...

ZgarbIntroduction In this challenge, your task is to decide whether a given sequence of numbers can be separated into two subsequences, one of which is increasing, and the other decreasing. As an example, consider the sequence 8 3 5 5 4 12 3. It can be broken into two subsequences as follows: 3 5 ...

 
@NewMainPosts Another doable one! Though this is probably more tricky...
 
@Zgarb Can [1,2,3,4,5] can be broken into [1,2,3,4,5] [], or does it need a non-empty descent like [1,2,3,4] [5]?
 
@Geobits They can be empty too, I'll add an example.

@aditsu CJam really needs a simpler way of counting the iterations of while loops. e.g. operators that increment and get some sort of counter, or an infix operator which adds the top of the stack to a variable without pushing that variable.

Jenkins?
 
@durron597 I was about to ask: for the avoidance of doubt, does "separated by empty spaces of unknown, positive length" mean that the first filled space must be the first character, and the last filled space must be the last character?
 
@PeterTaylor I think that's clear from the examples, but I added a sentence anyway.
(yes, you may have extra spaces at the beginning and end)
 
Another question I just looked at has examples which are blatantly wrong. It's always dangerous to infer spec from examples.

I've been meaning to ask: What is your avatar?
It looks like a yellow Sonic the Hedgehog in front of something Escher would make in Minecraft atop wallpaper of the big bang.
 
@AlexA. It's El'endia the Hedgehog. A recolor of Sonic the Hedgehog. I made the background in Blender. Actually, one of the first things I made in Blender.
I've had thoughts about making a better avatar, using Lumien the Hedgehog instead (he's not a recolor, and is also the main character of my novel-in-progress).
 
Is El'endia the Hedgehog a thing?
Are you making a Sonic fan novel?

Sorta? It's based in the universe, but it's less a fan-fiction and more of a homage.
 
Ah, okay.
 
@El'endiaStarman 0.1, 4 days ago. 0.7, 13 min ago. That was fast :P

Also if you still have g/p I'm pretty sure you could probably do that to get rid of the Os

@Sp3000 I'd still have to have at least one.

No need to be sorry, just wondering.

@AlexA. I downloaded the software.
 
Nice.
Note that I wrote my submission using Julia 0.4.0 and if you installed Juno, that's packaged with 0.3.10. I haven't tested the code using 0.3.
They changed quite a bit between 0.3 and 0.4 and actually removed some of the nicer golfing features.
 
For example, to convert a string to an integer, you can do int(s) in 0.3 but you have to do parse(Int,s) in 0.4.
They're talking about removing * for string concatenation and ^ for string repetition in 0.5. :(
 
I'm not really the rioting type. It'd be more like .
 
11:16 PM
^^
 
I'd be surprised if Julia ever won a code golf challenge anyway but I don't want it to slip into Java territory.
 
But trust me, bitching about idiotic changes in new compiler iterations doesn't do a thing. I've tried that for years with AutoIt and all I've managed to do is that now none of the devs like me anymore...

@CᴏɴᴏʀO'Bʀɪᴇɴ What OS are you on?
 
@AlexA. Windows 8
 
Boo
 
11:21 PM
The one dev that constantly agreed with my rants stepped down from the team after having ... communication problems with the other devs (but they left all her easter eggs in the compiler \o/) :(
 
What Easter eggs were left in the compiler? I kind of have a feeling that Easter eggs are things you don't want in a compiler.
 
@CᴏɴᴏʀO'Bʀɪᴇɴ I think you meant to say "I bought a PC with Windows 8 preinstalled and I'm currently in the process of switching to linux"
 
@AlexA. Well not so much easter eggs as features that are very useful to a handful of people (like custom Object interfaces to other frameworks [such as .NET])
@CᴏɴᴏʀO'Bʀɪᴇɴ Don't you xkcd me :P
 
11:27 PM
@CᴏɴᴏʀO'Bʀɪᴇɴ I don't do a whole lot through browsers (haven't really embraced "the cloud" yet) so for me there's a huge difference between operating systems.
For example, Windows is completely unusable and OS X is the best.
 
@AlexA. I know, me too :P It was related
And no!
I use windows; I am using windows; ergo, windows is usable.
 
You only think you're using Windows.
 
You're actually struggling through the awfulness that is Windows. One day you will be enlightened and never look back.
 
11:30 PM
Why Firefox and Chrome?
 
I'm using Windows 10 and arch linux about 50% each on my machines. I virtualize OS X on Windows using VMWare which is quite nice.
 
There was a point where my flash wasn't working on Firefox. @AlexA., so I used chrome w/ built-in flash.
 
I think you are confused.
flash is supposed to not work.

If you use anything that uses flash, you are objectively wrong.

True story: For whatever reason, when I was young and naïve and using Windows, my browser was Safari for Windows. One day it stopped letting me scroll up; I could only scroll down. So I switched to Chrome. (Disclaimer: Safari works great on Mac.)
 
@minxomat I have no opinion on Flash but I love that sentence.
 
@minxomat There aren't too many good HTML5 games
 
@CᴏɴᴏʀO'Bʀɪᴇɴ That's what Adobe AIR is for. Keep flash away from your browser.

Sorry for being impatient, I'm just bored and have decided that harassing you into running my code is a decent passtime.

The first time you run using Requests it'll precompile the module which might take a bit and may or may not generate tons of warnings.

The BASIC Stamp is a microcontroller with a small, specialized BASIC interpreter (PBASIC) built into ROM. It is made by Parallax, Inc. and has been popular with electronics hobbyists since the early 1990s because of its low threshold of learning and ease of use due to its simple to understand BASIC language and excellent documentation. == Technical specificationsEdit == Although the BASIC Stamp has the form of a 24 pin DIP chip, it is in fact a small printed circuit board (PCB) that contains the essential elements of a microprocessor system: A Microcontroller containing the CPU, a built in ROM...
