It does use a wrapper, viewable on GitHub, for the site-wide navigation panel, but you can load it without wrapper.

This seems promising. Now the only obstacle left is learning an entire new language with a much large alphabet than I'm used to. This may take some time...

And someone finally tricked me into playing 2048. Back in a few months...

@trichoplax easy. vm2 the JS

Not sure if there's a nice web version of vm2 though, and not sure how much it'll affect performance

Question: is $\forall x \in \mathbb{Z} : \ln(x) \notin \mathbb Q$

Anonymous

@Downgoat No: ln(1) = 0

However, that holds for all x > 1

Downgoat

do you have a link to a proof?

e is not integer though

oh wait i can't read sorry

Basically: if ln(n) = a/b for an integer n > 1, then n**b = e**a, and thus e is a root of x**a - n**b, and therefore an algebraic number. But e is a transcendental number, so contradiction. Therefore ln(n) is irrational for all integers n > 1.

Downgoat

oh ok that makes sense thanks

quartata

@Mego you mean e is transcendental at the end tbere

@quartata Yeah that one. I'm tired :P

Anyone up for a challenge tonight, have a look at this secret santa problem I just posted in math SE: math.stackexchange.com/questions/2896780/…

Is this on-topic?

J. Sallé

@Mr.Xcoder Not the way it's been proposed, I think? If someone rewrites it, I think it could be a decent challenge

Mr. Xcoder

I don't have a strong opinion, so I'll leave it up to others to decide whether it's on-topic or not. Now, I think it is understated and that it is somewhat close to the edge of our scope.

Q: Base64 in image that decodes to the image itself

Can you make an image (any format, any compression level), with readable base64 in it that decodes to the image itself? If yes, provide the image and base64. If no, prove that it cannot be done.

@Mr.Xcoder no objective winning criterion, popularity-contest isn't magic getaway

Mr. Xcoder

I overlooked the pop-con tag, it is close to being off-topic anyway even with another winning criterion

I've VTC'ed as unclear because it is understated anyway.

Any way to classify that as a programming-puzzle?

Erik the Outgolfer

are we given anything?

Neil

13:43

how can it be possible? readable base64 is at least 32 bits per 6 bits of data

Dennis

I doubt it's possible for most definitions of readable.

I just read that Elon Musk's Chicago tunnel plans to use Chicago's dirt as load-bearing walls. Chicago is built on top of a swamp. It's dirt is swamp dirt. He's going to get people killed.

Building a city on top of a swamp also seems like a good way to get people killed. Just saying.

Q: A greeting bot for a colleague from work

I have a colleague at work that works from home every Tuesday and Thursday. At around 8:00 AM he sends us a message with the following text: Hello today I'm working from home In order to relieve him from the burden of doing this every day he stays at home, we would like to automate this tas...

@Mr.Xcoder this feels more 'too broad' than off-topic imo

Mr. Xcoder

@Downgoat If I could, I would have voted for off-topic, too broad and unclear all at once.

Erik the Outgolfer

if you can understand it's off-topic, then it's not unclear enough for you to determine a close reason ;-)

quartata

@Dennis that's fair but it wasn't underground

A good chunk of the Pedway is underground, though.

@Pavel a professor once told me that he'd fail anyone in the class who hadn't had at least one part of the last assignment's code copied from SO or similar sites. Turns out he was just kind of joking
