"habbits" - are those like hobbits?

Geobits

@KennyLau I'm surprisingly okay with that. I laugh at our questions sometimes too ;)

zyabin101

@aditsu No.

Habit rabbits.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

What to flag for needs serious editing and formatting fixes?

Geobits

Things that need serious editing and formatting fixes.

quartata

The lazy way to do this would just to be use OperServ and issue the svsnick like that

aditsu

17:01

I heard that some people use "urban" as a code word for "black"

Eᴀsᴛᴇʀʟʏ Iʀᴋ

what flag reason though, should I just put that under moderator intervention?

quartata

@EᴀsᴛᴇʀʟʏIʀᴋ Don't flag, edit it

Geobits

Yea, only flag if you don't have the time, inclination, or ability to edit yourself, but it's better to just take care of it if possible.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

okay.

aditsu

@zyabin101 google image search for habit rabbit has some… interesting results :/

zyabin101

17:03

@aditsu Show. Show!

Geobits

Not in here please

quartata

@zyabin101 You do NOT want to see

Adnan

@aditsu ( ͡° ͜ʖ ͡°)

Maltysen

@aditsu oh dear

aditsu

if you do want to see, you know what to do

Geobits

17:03

My initial expectation was matched by google's results.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

rofl

what item?

Geobits

Some sort of rabbit is my guess.

Maltysen

@EᴀsᴛᴇʀʟʏIʀᴋ the habit rabbit...

Eᴀsᴛᴇʀʟʏ Iʀᴋ

oh

I guess they don't want it back. :P

Fatalize

17:06

@aditsu a smaller version of this

aditsu

@Maltysen well, just be gentle and try not to break it :)

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@Fatalize oh, is that what your avatar is from?

@aditsu s/:)/( ͡° ͜ʖ ͡°)/

aditsu

@Fatalize with the Λ super-imposed on the y, I see

Fatalize

y is made to look like a ∨

kinda

or ∨ is made to look like a y

Eᴀsᴛᴇʀʟʏ Iʀᴋ

∨ is logical or.... :P

aditsu

Fatalize

well yeah that's the point :p

Eᴀsᴛᴇʀʟʏ Iʀᴋ

okai

I should really get around to learning prolog.

aditsu

why?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

because it sounds cool

Fatalize

it's generally not a useful language to be an expert at, but it's good to know how it works

aditsu

17:12

@EᴀsᴛᴇʀʟʏIʀᴋ then maybe you should learn cool

Eᴀsᴛᴇʀʟʏ Iʀᴋ

cool

woah

mind reading alert

aditsu

so anyway, these days I've written over 50 classes for data structures and algorithms

mostly graph stuff

Maltysen

code jam is at 6 in the morning for me :/

zyabin101

Somebody said code jam! @_@

aditsu

5 pm here, but 6 am would be ok too ^_^

zyabin101

17:19

I just planned a leaderboard for that time.

aditsu

you can do it later

zyabin101

@aditsu You can't.

It's 2 hours and a half.

aditsu

you can do the leaderboard later :p

Kenny Lau

We haven't had any new challenges for a long time... could anyone here post one?

zyabin101

What if he wakes up at 9 in the morning?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

17:21

@KennyLau ???

we have?

Kenny Lau

@EᴀsᴛᴇʀʟʏIʀᴋ No, we don't.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

you mean chat mini-challenges?

Kenny Lau

well I'm also fine with those

Q: Find a maximal rectangle of 1s

Background I want to buy an plot of land and build my house on it. My house should be rectangular, and as large as possible; however, the available plots have lots of rocky areas that I cannot build on, and I'm having trouble fitting a potential house on the plots.

Code jam starts at midday here.

Let's share where code jam starts where you live.

Kenny Lau

@EᴀsᴛᴇʀʟʏIʀᴋ you can stop posting them. I know they exist. But you see, they are not interesting.

zyabin101

I'll start. 12:00 PM here.

aditsu

there's no such thing as 12 pm

Geobits

17:23

Uh..... yes there is?

zyabin101

12:00 here.

Kenny Lau

you meant 12 am?

zyabin101

12:00 PM here.

aditsu

nope, pm means after 12 noon; 12 is neither after nor before

Maltysen

@aditsu 12 pm is before 1 am, right?

quartata

17:24

That always hurts my head

zyabin101

Noon here.

@_@

trichoplax

Why are we using 12 hour clocks???

2

Kenny Lau

oh, that's 12 pm, I thought midnight

Geobits

No, 12 AM is midnight.

quartata

12 PM is noon 12 AM is midnight

aditsu

17:25

see? that's EXACTLY why there's no such thing as 12 pm (nor 12 am)

zyabin101

@quartata Definitive guide.

Geobits

@trichoplax While I'm usually in agreement with that, It's hard to agree with "it doesn't exist" :P

aditsu

they are devoid of meaning

Kenny Lau

@EᴀsᴛᴇʀʟʏIʀᴋ Do you have mini-challenges?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@KennyLau they are actually kinda cool

quartata

17:25

@KennyLau Chill, we don't need to have a challenge on the site every day :P

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@KennyLau brb finding my folder of them

quartata

They won't take away our graduation or anything

Geobits

Well... they might ;)

At least postpone it until November or so.

trichoplax

@Geobits Oh I agree - it just seems like arguing over middle english spelling or the correct way to load a printing press...

Fatalize

24h clock > 12h clock

Geobits

17:27

@trichoplax Yea, but even with 24 hour clocks, people still argue about 2400 vs 0000 in my experience :/

Eᴀsᴛᴇʀʟʏ Iʀᴋ

^

IMO 0000

Fatalize

no one ever says 24 hour something

VTCAKAVSMoACE

@Fatalize 0000 > 12:00 AM

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@Fatalize 24 hour time.

aditsu

@Geobits those are both unambiguous though

Kenny Lau

17:28

it's definitely 0000

VTCAKAVSMoACE

24-hour time is golfed

Fatalize

I've never heard someone use 24h... instead of 00h...

Geobits

@aditsu So is 12 PM >_>

Eᴀsᴛᴇʀʟʏ Iʀᴋ

aditsu

nope

zyabin101

nope

Geobits

@Fatalize I have. Especially say, on listing business hours. It may say something like 0900-2400.

Kenny Lau

Why don't we just encode the time in 2 characters of base 64...

Eᴀsᴛᴇʀʟʏ Iʀᴋ

When you scroll through the question list and mis-read trits as tits. >_>

zyabin101

Fatalize

17:29

@Geobits Never seen that. Then again in France we close shops at 5pm

Geobits

@Fatalize It was pretty common in Japan at least. Also on military bases. Maybe it isn't so much in Europe in general.

quartata

@zyabin101 You mean Organ Trail, right?

trichoplax

zyabin101

@quartata No, I mean Oregon Trail.

Organ Trail is very spooky.

Geobits

The way it was explained to me was that if they were stressing they were doing something late they'd use 2400. It would depend on the time span, too. You wouldn't really see 2400-0600 for example. I think they just liked to not "wrap" the time if possible.

I've even seen 2600 for 2AM on one occasion. It was weird.

Fatalize

17:32

24 as limit is acceptable I guess

but 24:01 is not

aditsu

Geobits

IMO it is if you're expressing a time frame and don't want to list both dates. It's easier to say "Friday, 2000-2430".

Agawa001

@trichoplax because distinguishing 24 hours a day is harder than when it is divided by 2 for a normal human brain ?

Fatalize

@Agawa001 only because you're used to it, I don't have to think to know what 19:00 is

Agawa001

@trichoplax dont think so, since there is a suffix to define pm or am

Geobits

Half the clocks in my house are on 12, half on 24. Gotta keep the kid on his toes.

Agawa001

17:35

@Fatalize Im not used to it

i must always subtract 12 to know

quartata

I have my alarm clock still set to standard time

Fatalize

well yeah

You

When I look at my clock and see it's 1:00, I think, "Wow, it's quite a bright night!"

Fatalize

cause you're used to the am/pm things

Agawa001

not 12 , but 2 .

Fatalize

17:36

I don't subtract anything when I read 19:00, I know what hour it is

trichoplax

@quartata UTC?

ostensibly it's to be rebellious but really I'm just lazy

Geobits

Lazy rebellion is the best rebellion.

zyabin101

@aditsu See ^^^^

Kenny Lau

17:37

@EᴀsᴛᴇʀʟʏIʀᴋ Have you found it yet?

trichoplax

@quartata I'd be rebellious about it too, if I was less lazy...

zyabin101

Who here wants to play Oregon Trail? :3

trichoplax

It would take me more effort to set my clocks to not automatically update

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@KennyLau no was too busy de-spamming qpixel

Kenny Lau

alright

quartata

17:38

@EᴀsᴛᴇʀʟʏIʀᴋ Did you delete my posts

My rep went down

zyabin101

@EᴀsᴛᴇʀʟʏIʀᴋ How?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

delete button

zyabin101

@EᴀsᴛᴇʀʟʏIʀᴋ How'd you get 1000 rep to do that?

He's a mod, he doesn't need it.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@quartata probably

quartata

17:40

@EᴀsᴛᴇʀʟʏIʀᴋ that really rustles my jimmies

You deleted the one post on the entire site that wasn't spam

Which was the Markdown support feature request

ok

Eᴀsᴛᴇʀʟʏ Iʀᴋ

it was a dupe

Agawa001

@trichoplax thing i m more annoyed to , are these wall clocks not enumerated from 1 to 12

quartata

No, it wasn't.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

yeah

it was

zyabin101

@EᴀsᴛᴇʀʟʏIʀᴋ ಠ_ಠ

You try to clean up QPixel.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

wait where?

quartata

I mean who gives a shit anyways

zyabin101

You do the opposite.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

I didn't delete yours, only adnans.

@quartata iirc yours still exists

quartata

But it was the question...

Adnan was the person who asked the question

zyabin101

You downvoted posts which are not spam.

I lost a lot of rep by that.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

17:44

I actually haven't downvoted anything, except the anti-small caps answer.

Geobits

Oh, I did!

Eᴀsᴛᴇʀʟʏ Iʀᴋ

wizzwizz4

It was probably Downgoat. Because goats press anything that points down.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@quartata @zyabin101 ^^^

@wizzwizz4 TIL

Agawa001

@Geobits you ll share the blame of all dvters until you change this avatar

zyabin101

17:44

By that, and also by the reason that you have gone above and beyond laws of mathematics, I have to become ignorant of you.

Don't ping me again.

Fatalize

I don't understand anything of that conversation

quartata

Nor do I.

Geobits

or ?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

17:45

If the input has a decimal point/is float, output the degrees, minutes, and seconds (rounded to the nearest second).

Geobits

Oh, I thought you just meant pick one or the other :P

wizzwizz4

Ok, I've set up a chat bot. Ping me with /mini1 *input*

Agawa001

@trichoplax i mean who is the genius who can tell the hour few seconds from taking a first glance at this

Eᴀsᴛᴇʀʟʏ Iʀᴋ

If the input is in x°y'z", output degrees to the highest precision your language can handle.

Agawa001

Geobits

17:47

That's a pretty terrible clock.

trichoplax

@wizzwizz4 In here or in the bot testing room?

(hint: shouldn't be in here...)

Agawa001

yes, i used to stand arround 30 seconds next to it to calculate the actual hour.

Geobits

@trichoplax Aww, I had my flags all ready and everything :(

trichoplax

lol

@Geobits don't abandon hope yet - I only hinted...

Geobits

True. I'll keep them on standby for now.

zyabin101

17:49

@wizzwizz4 /ಠ_ಠ

Agawa001

luckily, the linked wall clock isnt divided by 24, luckily

zyabin101

@wizzwizz4 /mini1

Geobits

That's pretty much the one advantage 12 hour clocks have. It's much easier for analog at a glance.

Agawa001

but if it is, children may grow smarter

wizzwizz4

I don't actually know how to use the chat API yet, so I'm copying and pasting stuff into it...

zyabin101

17:50

@wizzwizz4 /mini1 input

trichoplax

If you have a 24 hour analogue clock then you can paint images of the time of day around it...

Geobits

Eeeehhhh... that would be highly season/location dependent I think.

wizzwizz4

@zyabin101 Pending...

Geobits

Is 7 sunrise, or is it 5?

trichoplax

@Geobits I think that's an excellent argument for 4 or 6 or 8 hour analogue clocks

zyabin101

17:52

@wizzwizz4 /stop

ಠ_ಠ

ArtOfCode

...did you lot seriously have an argument about posts and rep on QPixel where they matter even less than they do on SE?

Geobits

@trichoplax Probably, but I think thirty degree segments are a nice compromise.

trichoplax

@Geobits Good point. Maybe a 365*24 hour clock then...

zyabin101

I think chatbots in the Nineteenth Byte aren't welcome here.

wizzwizz4

@zyabin101 No need. It crashed when I put that into it.

@ArtOfCode Exactly - they aren't even real fake internet points!

Does it count as "running a bot" if the only things it can say are being reviewed by a human before posting?

ArtOfCode

gonna go with yes

wizzwizz4

17:54

@trichoplax Gonna go with "no", because the human is responsible for not putting in spam.

Fatalize

So now I see QPixel, but what really is it?

Geobits

I'm not running a Turing test here. If it looks and acts like a bot, it doesn't belong in here.

but it is still a bot... toss-up
