@Dennis Oh :-) Thanks. I didn't ask you to pull yet just in case I included some more changes (which I haven't). What was the word? Not to pester you unnecessarily

2 days ago, by Downgoat

@Dennis there was a bug in that version of wrapper too >_> can you replace it with this version? (i'll try to integrate wrapper with cheddar npm module ASAP so i dont have to pester you with this >_>)

2 days ago, by Luis Mendo

"pester" Funny how English has a word for everything :-) In Spanish we would have to use an expression, or a verb that has a more general meaning

El'endia Starman

@quartata Holy cow, RIT got a special one!

@El'endiaStarman Yeah, I'm surprised you never saw it :P

El'endia Starman

Well, I graduated in 2015. I wasn't at RIT anymore.

Hahahaha

Comic was April 1 2012

@LuisMendo Well, I was eager to try out the bitwise goodies. :)

@TimmyD What are you saying about dogs?

El'endia Starman

@quartata Oh.....okay. Well, in my defense, that was four years ago? :P

@Dennis :-) I hope I didn't screw it up. I did some tests and it seemed to give the right result (works only in the range -2^52:2^52-1, at least for now)

Yeah, the ones I tested worked as expected.

Good to know, thanks!

10:05 PM

Thanks a lot @quartata, I just read through the entire explain XKCD article when I was hoping to do something productive.

No problem

El'endia Starman

@DJMcMayhem Same for me. :P

It was worth it though :)

@ConorO'Brien Can you again give me the link to your new comic/blog?

@flawr cergos.cfw.me

nothing new besides the one comic

10:11 PM

What! No Jolf?

I penciled up a comic but I'm too lazy to ink it by hand. I was wondering if I could scan it and do edge detection to work with it

That's exactly what I imagine java sounds like.

Verbose and respectful?

El'endia Starman

@ConorO'Brien Me likey. The HTML example kinda bothers me though... ಠ_ಠ

@LuisMendo Well put

10:12 PM

@LuisMendo golfing languages later ;)

@ConorO'Brien Haha ok

V plz?

@El'endiaStarman haha :3

@quartata Link?

@DJMcMayhem will do.

10:12 PM

It's a physical piece of paper

\o/

@LeakyNun '*'#~>:/~i.10, J

@DJMcMayhem thanks :)

El'endia Starman

@El'endiaStarman Actually, it's syntactically valid with regards to the opening and closing tags. I thought it wasn't at first. On the other hand, the bit.ly link doesn't have quotes around it, and the first a tag doesn't have an href.

@quartata Why you could still share a tinyurl.

I don't know how to make a URL to a physical object

do let me know

10:13 PM

Does anyone know what attribute Python's / calls internally?

(Python 3)

__div__ I think

@El'endiaStarman you can go deeper and say that a lot of web dev's learn HTML but not necessarily correctly.

@quartata at least give us the IP

127.0.0.1

feel free to ddos

@quartata No, there is no __div__ attribute in version 3.

10:15 PM

@Dennis Huh. One second

@quartata I need the sha256 hash to make sure it installed correctly

It's truediv

Yeah, __truediv__

Ah, found it. __floordiv__

I just did dir(1)

10:16 PM

Eh, typing fail. I wanted //, not /.

@Dennis That's integer division I assume

Yup.

@Dennis and you keep saying that Jelly is bad with strings?

A: Lemon-Limify a String

Jelly, 32 26 bytes ³L_+«0ị“~ ”«³ḣ JµṖ;Ṛç@þ`j⁷ Try it online! EDIT: Dennis saved 6 bytes. Thanks!

It seems that I am bad with strings. This is the second string challenge where Lynn outgolfed everyone else with Jelly.

Still one of the longest jelly answers I've ever seen. :P

10:19 PM

I find it surprising that the challenge has two CV as unclear. Granted, the spec relies on the examples, but the examples do make everything crystal clear, don't they

^

We have a de facto rule that examples, however clear, don't replace a specification. I agree that it's a bit of overkill here, but both positions are reasonable.

I need two names for clocks.

What sort of clocks?

Doesn't really matter

10:32 PM

Watch, hourglass?

time clocks

What does time specify in time clocks? Are there clocks that don't refer to time?

From MS Word synonyms: time piece, chronometer

Well I was thinking more whether these are physical clocks that are going somewhere, as opposed to, say, a clock circuit

I have an idea for a challenge:

timepiece

10:34 PM

timer

There are two clocks A and B

and I sequentially randomly write down the current time of A or B

A: 10:30, B: 14:12 B: 15:30, A: 11:01, B: 17:30

Now you need to find out by how much they are off

Is there a unique solution to that?

No

So any will do?

Nice

And that is one debatable thing: Will just any do, or should the participats find the minimum or/and maximum? (Under the assumption they have the same speed)

10:37 PM

Let me add another debatable thing: the "HH:MM" input format may be unnecessarily complicating the challenge

Or another idea: Find the minimum/maximum speed difference between the two clocks (assuming both have constant but perhaps distinct speeds)

I guess min and max makes more sense, yes (assuming same rate)

Which one of those do you think are the most interesting cases?

I think min/max with same speed

Are all these times are on the same day?

10:39 PM

That doesn't really matter, i thought of just providing floating point numbers between -infnitiy and infinity

Another idea would be using integers, but that is boring as you can easily bruteforce it

If that's the case, isn't the minimum zero?

No, consider A: 1 B:10, A:5, B:11 here the clocks are at least 5 hours of, but at most 9 hours

I think he means the maximum possible minimum

Or are these times sampled regularly?

No

10:42 PM

A picture would be great to clarify the challenge

A simple one with two time lines and epochs on each

I thought about that, but I have no idea how to effectively visualize it.

Then I don't see why it can't be A:1 Mon, B:10 Tue, A:5 Wed, B:11 Thu

can anyone familiar understand why these two lines in my gitignore are not wokring:

node_modules/*
!node_modules/atob/

@Sp3000 No, I mean you get like an unix timestamp or somethign like that, that is continuous

@El'endiaStarman How do they know who was the guy who shared the link?

10:58 PM

Is there an english expression for when a clock is behind or in advance of the real time?

"off"? said a non-native speaker :-P

@flawr You could say the clock is n minutes fast or slow if it's ahead or behind the actual time respectively

George V. Williams

@flawr, "running fast/slow" or "early/late"

Thanks for your suggestiosn! I wanted to avoid fast and slow, as the clocks should have the exact same speed.=)

off sounds good

11:02 PM

Ah, and I want to indicate in what direction the clock is off.

I think I go with ahead/behind.

^^ Sounds good to me

@Doorknob o_o I just realized your avatar actually is a doorknob. I always thought it was some kind of modern art.

@flawr what else did you think it was ( ͡° ͜ʖ ͡°)

It's different forms of a doorknob. I liked the old one better :-)

@quartata do you know if it's possible wait a certain period of time in source/tf2 scripting?

11:06 PM

@ConorO'Brien There is a command called wait that waits one tick but it is disabled on most servers

Yo, being "doper fast" would be the shiznitz. — FuzzyBoots yesterday

Q: Make a (somewhat) self-referential string

You want to make a string where the (1-indexed) character at index n is n. When n is less than 10, this is easy: "123456789". When n is 12, for example, it becomes impossible, since numbers greater than 9 (in base 10) take up more than one character. We can compromise by dividing the string into ...

@quartata Are you interested in someone inking it for you?

I'd rather try it by hand first

hi I have a question, can my title be unicode characters

What’s the title?

Ⓣⓔⓧⓣ ⓘⓝ Ⓒⓘⓡⓒⓛⓔⓢ

Kinda difficult to read in small fonts

I think that's a bad idea

11:18 PM

ok

@qwr Hm, I'd avoid it. Some people might not be able to see it

it's also a bit hard too read

A: Is Unicode in Hot Network Questions question titles allowed?

It is certainly allowed to use Unicode, when appropriate. We don't discriminate :-) On the other hand your question had a title which, in my opinion, used Unicode as decorations and needed improvement. Do use descriptive titles and avoid flashy decorations. If you want more views for your ques...

I've never used the sandbox maybe I should :/

@flawr is of should read is off

It never hurts. Even when you are more experienced at writing challenges there are things you might overlook

11:22 PM

@qwr That's always a good idea. Every challenge almost always benefits from at least a little time in the sandbox

ok i'll try it out there

Speaking of sandbox, does this look ready to post:

wat? who starred that?

I think my challenge is pretty easy but i'll test it out in the sandbox

@LuisMendo thanks

ok so the challenge will be to turn alphanumeric characters into a unicode equivalent. What do you guys think of a bonus for also outputting a variant

For example turning a into ⓐ and then a bonus for also outputting 🅐

nah scratch the bonus that's kinda weird

because negative variants only exist for capital letters I think

@Doorknob dot-repeat? not much of a vimmer

(You could probably do some magic to auto-detect the amount of indentation, but that's probably more trouble than it's worth)
