@totallyhuman Please don't post nonsense.

@Riker Trying to understand chatiquette. How was that message allowed?

Fatalize

Sometimes I feel like Riker's main contribution nowadays in chat is posting images found on Reddit

Adám

8:08 PM

@Mego totallyhuman at least posted something related to programming. Possibly frustration with Java, or an exclamation based on how un-golfy Java is. Riker's image has no apparent (to me, at least) context in this chat room, nor any connection to programming contests or code-golf. Maybe on english.SE it would be appropriate because of the peculiarity of English pronunciation of bread vs bred.

Anonymous

@Adám There's a significant difference between posting a funny image to chat and entering, saying one nonsense message, and immediately leaving.

Fatalize

That would be true if Riker didn't post such images at least twice a day, or so it seems

Anonymous

I agree that it's a bit much at times.

@Riker Could you please tone down the frequency of your image posts? It's getting to the point where they're making up a large portion of your chat contributions.

@Riker I would say something like: "May nothing bind us, so nothing will tie us".

I'd like to replace "tie" by something more literary. "Amarrar" sounds somewhat literary

I see now that my translation is not that much different from the one you linked :-)

Zachary T

@Adám, I have to ask, why do you consistently use the ‽ mark in your sentences?

Riker

@LuisMendo ah, okay

Luis Mendo

@Riker From The Princess Bride :-)

Riker

yep

Luis Mendo

I like that quote

And that character for that matter

Adám

8:54 PM

@ZacharyT Why‽ Why not‽ Because it so exactly fits what I'm often trying to express.

Riker

lol

Luis Mendo

Oh, and the music! Mark Knopfler is such a great composer

Adnan

@ComradeSparklePony Yup, Riley is right. And if you also want to automatically sort it, you can also use ê

Zachary T

I understand why your using it. But, I'm wondering as to why you use the unicode ‽ rather than ?! and/or !?. Do you have it on your keyboard or something?

Riker

it's on mine

Adám

8:58 PM

@ZacharyT I think ?! and !? are ugly, and I've made my own keyboard layout that has it.

Zachary T

Oh, that makes sense.

Adám

I've reserved 6 keys as prefix keys, so I've got about a thousand available slots.

Zachary T

Wow.

Christopher

I applied for my first job and didn't get it (ノ°Д°）ノ︵ ┻━┻

I mean, you're the RO, and you do you, but I'm saying, I don't think the trash was entirely necessary. A warning was sufficient, and if it continued, by all means, use the trash

Adám

@ZacharyT All the other characters are valid APL identifiers.

Anonymous

@ConorO'Brien The trash can is for getting rid of messages that don't belong in the room. It's not a disciplinary action. Warning + trash is the ideal solution to a small problem like that one.

Anonymous

If it had continued, then kicks would've been issued.

The irony is 3 messages getting trashed caused 12 messages about it to be posted.

Zachary T

9:10 PM

Woah, thanks didn know they were valid identifier names.

Adám

@Mego Whoa, I didn't mean to spam at all, only to inspire others who might need lots of special chars for golfing langs.

Zachary T

*didn't, was in French keyboard for some reason.

Conor O'Brien

@Mego that's quite arbitrary IMO. what's to stop an RO from trashing a side discussion that "doesn't belong"? nothing much, as it seems

Anonymous

@ConorO'Brien ROs are expected to use their discretion when moderating. A side discussion that was disrupting other discussions (especially PPCG-related discussions) would be moved to its own room, not to the trash. Nonsense gets trashed.

Conor O'Brien

I wouldn't quite call it nonsense--no more nonsense than the average bad pun

I do applaud you for doing your job tho, what you says makes sense.

Adám

@all How do you insert special chars for golfing langs with custom char sets?

It's easy to remember, AWS form a ^, they are ´^`

Anonymous

Also if it's a char whose ordinal I remember, I'll just alt-code it in

Adám

9:16 PM

APL+Shift+T is ⍨ in standard Dyalog mapping, (I use AltGr as APL key), so it is surrounded by its parts: R is ¨ and Y is ~.

Adnan

@Adám alt-gr on windows

for cp1252

Adám

U is _

Anonymous

For example, I know ♂ is ALT-11, but I don't remember ⌠ and ⌡ off the top of my head, so I have to copy those in

Conor O'Brien

@Adám for APL, I do the ` + key thing. for other languages, I google them (since most languages I use tend to be exclusively ascii)

Zachary T

Yeah, same here Conor.

Adám

9:19 PM

@ConorO'Brien ` as shifting or as prefix key?

as a prefix key

Like TryAPL

^

I've got to set up a custom keyboard mapping for IPA and APL (combined) sometime.

Adám

´^`¨~_ are taken with a lot of breadth. E.g. ~1 gives ¹

@ConorO'Brien I could never use a prefix key for APL. I tend to type multiple APL chars at a time, so I hold down my right thumb (or left pinky, CapsLock=AltGr) while I type with my other fingers.

Conor O'Brien

9:22 PM

Adám

CMC for a given n, generate (1...n)/n

Anonymous

@Adám Is that sum(range(1,n+1))/n?

Adám

@Mego no, the result is a list of n items

Anonymous

Oh

Adám

the last item is n

the first is 1/n

Anonymous

Wait so it's not [x/n for x in range(1,n+1)]?

It would still be 4 on US standard layout, but you'd release the shift before the /

Adám

@Mayube No, it is the bottom-rightmost key.

@Adám On US layouts, sure

Spanish layout

Adám

So it may be advantageous to enter all shifted keys, then press left e.g. Ctrl-LeftArrow and then an unshifted key.

Anonymous

9:40 PM

You should make a challenge about this: given a string, output the shortest series of keystrokes needed to type that string

Adám

But this is actually pretty cool. If code golfing is about entering as little as possible, what good is it to have to copy from a map all the time. Keypresses!

@Mego Using which layout?

ACTUALLY, an abomination is if there were a keyboard where everything except a few keys are dead

@ZacharyT keyboard works fine, but the backspace and delete keys are both dead

@Mayube Or a totally normal keyboard, but Enter is dead. Need Ctrl+Alt+Shift+F3,AltGr+Space to do Enter.

@HombaHelka The challenge you responded to is a "code golf" challenge (as are most challenges posted on PPCG), the goal of such challenges is to complete the task in as few bytes of code as possible. 32 bytes means your code takes 32 bytes. In the vast majority of normal languages, 1 byte = 1 character

@ZacharyT And Java's style recommends sameline open braces yet I still newline 'em. Plus the language is supposed to be golfy, doesn't mean I have to golf the interpreter :P
