@AdmBorkBork I'd doubt you could because not all the .NET languages support all the same features.

Is random.Next((x = something) * w, ++x * w) the same as random.Next(x = something * w, x + w)?

HyperNeutrino

@WheatWizard Ah okay. Thanks for your help though. Hopefully this interpretation will give me some hints on how to get this done :)

I'm still rather suspicious because the OEIS goes out of its way to create a very strange definition of the number.

Leaky Nun

@WheatWizard where?

HyperNeutrino

I don't like most OEIS descriptions. They're rather unclear and you can only understand them if you already know what the math means :P

@HyperNeutrino I think this one is very clear.

It's certainly concise.

Step Hen

HyperNeutrino

Very much so. It makes so much sense just from a first glance. :P

ppperry

Er, that isn't an actual sequence.

Step Hen

What exactly does n=1..0 mean?

HyperNeutrino

16:07

[1, 0]

ppperry

Also, what would have happened if somebody had posted a zero bytes answer in that challenge when you had to compute the all-zero sequence

Step Hen

@HyperNeutrino .. in my experience means a sequence

ppperry

(outputting by exit code)

Step Hen

@HyperNeutrino 1..n as in 1,2,3, ... ,n-1,n

HyperNeutrino

hm

Wheat Wizard

16:08

@StepHen It means its empty

Step Hen

@WheatWizard no, I mean what does that mean in mathematical terms

does it even mean anything

@totallyhuman apparent_encoding is what Python thinks the encoding is. encoding is what the response says the encoding is.

totallyhuman

@feersum yes that's why i was wondering what it's supposed to be

feersum

It's supposed to be http.cat.

apparent_encoding uses the chardet library to try to detect the encoding of the response, because sometimes the response lies.

That works because $args is an array and stringifying an array puts spaces between elements, but with only one element you get just that.

@HyperNeutrino I know it's no use now, but you could've removed all of your personal information from it, changed the OpenID registered to your parents', then the OpenID would be the only thing to be nuked.

@StepHen But doesn't the OpenID count as the account, as the thing that stores the personal data?

@HyperNeutrino Did the questions and answers remain?

Step Hen

@ConorO'Brien and I'm triply an idiot, I forgot what I thought of that fixed it

@ConorO'Brien it works

Conor O'Brien

good to know >.>

HyperNeutrino

@wizzwizz4 Yes, but I had to get them reattributed

@wizzwizz4 Actually, the reason they thought I was underaged (even though I was almost 15 at the time) was because I hastily nuked my PII

wizzwizz4

17:44

@HyperNeutrino Oh, good. So they're reattributed and everything's fine now?

I was an SO contributor from a <13 age.

I didn't have an account when I first started doing so, though.

Almost entirely because of the 13 age limit.
