0.828125 + 0.0009765625 = 0.8291015625, so you know the first 2 decimal places are definitely never going to change from 0.82

@DJMcMayhem hopefully that follows from the fact that 0.111... in binary is the same as 1 (adding 1/2 + 1/4 + 1/8 +... never exceeds 1)

DJMcMayhem

@trichoplax Wow, that looks awesome. It's a little more complicated than my challenges tend to be, but it looks pretty cool. Thanks!

trichoplax

I'm not sure how quickly it will lose meaning for a language that doesn't have arbitrary precision, so you might have to word it carefully, but it seems like it could give provable test cases

DJMcMayhem

Oh shoot, I didn't think about that....

Hmm, it seems like you could limit it to (2^32)^-1 or say that languages without arbitrary precision just can't compete

quartata

Does anyone know how to make a route in Google Maps? Like input a list of places and display a tour to all of them

trichoplax

I think you can select "add destination" once you have a route from A to B

May differ between mobile and desktop versions though

Lemme see

DerpfacePython

Heyo guys

H Walters

@DJMcMayhem In honor of your 12K: pasteboard.co/gD2hXI57U.png

quartata

@trichoplax Works, thanks.

Now to do it programatically...

DJMcMayhem

@HWalters Haha, thanks!

trichoplax

@quartata Are you using Google to solve TSP?

quartata

11:18 PM

No

I'm writing something for myself to create a random walk, literally

trichoplax

Just leave home with a coin...

quartata

That would take way too long

besides I'm bad at flipping coins and I thought it would be amusing to make something that was based on a set seed depending on what area you're in

H Walters

And he might get stuck at a three way fork forever

quartata

Oh, that'll happen regardless most likely.

"What's the traveling salesman problem?" "ugh, use google." (later) "holy crap where did you get the $1,000,000?" "Oh, I solved the traveling salesman problem." "How?!??" "You told me to use google, and I did."

quartata

11:21 PM

everyone knows TSP can be solved in O(1) anyways

DerpfacePython

Chuck Norris

Conor O'Brien

I hear you can solve it in O(0.67) if you have amazon prime

quartata

@DerpfacePython No, eBay

DerpfacePython

@ConorO'Brien What about Foresight?

βετѧ Λєҫαγ

@quartata No, Jon Skeet

Conor O'Brien

11:22 PM

what about it?

DerpfacePython

Solves TSP in O(-1000)

Solved before you even start trying to solve it

Conor O'Brien

ah.

Releasing Helium Nuclei

i solved in O(i)

quartata

How do I use HTML5 geolocation?

Conor O'Brien

swiftly

Releasing Helium Nuclei

11:25 PM

@quartata ugh, use google.

quartata

I get that navigator.geolocation.getCurrentPosition is involved somehow

But it appears to take something

Conor O'Brien

@ReleasingHeliumNuclei And everyone knows O(ai + b) = O(O(a) - O(b))

quartata

Oh, it's asynchronous

Conor O'Brien

voici

Releasing Helium Nuclei

@ConorO'Brien so, O(i)=O(1*i+0)=O(O(1)-O(0))

Conor O'Brien

11:26 PM

totally

quartata

How do I truncate a float in JS?

DerpfacePython

Ummm

βετѧ Λєҫαγ

Big O notation makes no sense to me. It's the one thing that I hate about programming

DerpfacePython

parseInt()?

quartata

I would do x | 0 but I get the feeling that I'd get yelled at

DerpfacePython

11:28 PM

That's the REALLY long way to do it

Downgoat

@quartata do that

its fastest way

quartata

@Downgoat All right.

DerpfacePython

How inefficient is parseInt?

quartata

Pretty slow.

At least, relative to a bitwise operator

DerpfacePython

Ah

Downgoat

11:29 PM

@quartata its also good idea to use that when casting from string to integer

the interpreter optimizes |0 very well

wat

quartata

I'd hope it would. It's one instruction.

DerpfacePython

LOL

I'm liking Qwerp-Derp over DerpfacePython

Downgoat

@ReleasingHeliumNuclei such wat

DerpfacePython

But for some reason my name here is still DerpfacePython

Releasing Helium Nuclei

11:30 PM

did it work

na

codegolf.stackexchange.com/users/56721/betseg says betseg, chat says rhn

trichoplax

@DerpfacePython It shows the name from your parent profile, which is still set to SO on your chat profile

DerpfacePython

Yeah

trichoplax

You can change your chat profile to show PPCG as your parent profile, then your name will show up in chat as the PPCG name

βετѧ Λєҫαγ

Okay, I'm back as none special character Beta Decay

Well I will be when my chat profile reloads

Downgoat

@βετѧΛєҫαγ :D :D :D tyvm

Beta Decay

11:32 PM

@Downgoat Haha no problem

I couldn't stand it either

Conor O'Brien

@BetaDecay Welcome back! I haven't seen you in a while.

Downgoat

okay changed my avatar back to normal downgoat

Conor O'Brien

;)

DerpfacePython

OK, should be changed

Releasing Helium Nuclei

@BetaDecay did ur naem changed fater bcoz u haz more repz?

trichoplax

11:33 PM

Beta Decay

@ConorO'Brien I was on holiday

DerpfacePython

Yup

Make like

A demonic chicken or smth

Beta Decay

@ReleasingHeliumNuclei yah

@DJMcMayhem ^ avatar-change-request

trichoplax

@Downgoat I tried refreshing your profile but you still have the dream version on your chat profile

Releasing Helium Nuclei

11:35 PM

did it work

nah

Beta Decay

Now, @ConorO'Brien let's talk about quines ;)

Thanks tricho BTW

Conor O'Brien

@BetaDecay oh yeah I still haven't posted it yet

Downgoat

@trichoplax can you try to refresh it now?

trichoplax

@BetaDecay I didn't need to do anything for yours - it already showed in latin letters :)

Beta Decay

Oh right haha

11:37 PM

The stealthy mod strikes again!

trichoplax

@Downgoat Done :)

Beta Decay

@ConorO'Brien Haha it's fine. I'm just rep whoring because I lost a lot today

Downgoat

@trichoplax :D tyvm!

El'endia Starman

Wait, does that mean I literally ninja'd trichoplax? :P

Conor O'Brien

@BetaDecay oh what happened?

trichoplax

@El'endiaStarman It's not difficult :P

Q: Outputting x to y

Challenge You must choose one number x (y = x + 9) and create ten unique programs which each print out one of the numbers in the range x to y inclusive. However, there are three twists: Each program's score is the difference between length of your program in bytes and n (where n is the number ...

Releasing Helium Nuclei

wow -9

Beta Decay

@El'endiaStarman For one, @trichoplax is a turtle

El'endia Starman

@trichoplax No, I mean, I refreshed Beta Decay's chat profile, but totally stealthily. So I beat you to doing it and I was like a ninja in doing so!

I feel like I have -15 tattooed on my forehead, reading Optimizer's latest edit :D

trichoplax

11:38 PM

@El'endiaStarman Ah I see - ninja in both senses... I just meant that being faster than me isn't a challenge...

Downgoat

@BetaDecay I think a general rule of thumb is: Should I write a trivial challenge and try to make it interesting w/ restricted source? -> No

Beta Decay

Haha yeah I guess so

Mathoverflow's design scars my eyes every time i look at it ;___;

Beta Decay

@Downgoat Mathoverflow just melts my brain

trichoplax

11:42 PM

Did you notice they appear on the HNQ but they don't have the HNQ on their site

Beta Decay

My eyes don't get a chance to be scarred

El'endia Starman

@trichoplax status-by-design

The MathOverflow people didn't want the HNQ sidebar.

trichoplax

I know - it wasn't a complaint :)

Downgoat

they also don't have meta links :/

Beta Decay

Hm, I think I just got a sympathy upvote. If it was any of you, here, please don't use your upvotes like that :)

Q: Let's improve the leaderboard snippet

The leaderboard snippet could use some improvements. Improvements usually fall into three categories: Formatting & CSS - make it look better Functionality - stuff it should do Misc - everything else Please answer with suggestions. I've added a few myself.
