@totallyhuman yes

not quite half but ye

and @flawr I did look at the other links you sent I just havne't had time to respond before now :D

10/10 would recommend again

@Riker don't get old

totallyhuman

@Christopher great advice..?

@totallyhuman From 2 weeks of work I lost about 80 bucks (expenses like gas)

Can someone post this question on puzzle meta for me?

"I tried to post a puzzle and it tells me I can only post every 40 minutes. I have yet to post today or even in the last few months what is happening?"

wtf even

musicman523

what a great challenge

totallyhuman

lol

ok so it turns out that the A<id>/b<id> for oeis doesn't even have a static limit

it keeps changing

musicman523

@totallyhuman I wonder if it's a sequence in the OEIS

totallyhuman

17:55

hehe

great i just hit programmer's block

it's when you don't know what to name a variable

musicman523

name it o

totallyhuman

why?

@Christopher puzzling.meta.stackexchange.com/a/6029/38270

Christopher

@HyperNeutrino That does not seem right. That was on a different SE

HyperNeutrino

but you have under 200 rep

therefore you are limited on any site with under 200 rep

it's to prevent spammers from spamming every site on the network

Christopher

18:06

Ah. Still dumb

HyperNeutrino

it's not a bug

that's a very strange bug

"rate limit on all sites combined with under 200 rep"

hm must be accident

but yeah even mods get this issue

hey what should the name of an exception that indicates that the given number was too high be?

why would you use that as a test lol

also can i see your code

i can show you mine too if it matters xD

you actually use json

Does part of that indicate the Mon? (other than that date being a Monday, obviously)

pretty accurate

that's invalid Jelly
so is it 05AB1E? :o

you know you can type your thoughts in one bigger message instead of 3 words per message :P

Conor O'Brien

I'm pretty sure you only needed 1 or two messages for that >.>

eh

better? :P

i personally

don't mind

Leaky Nun

stop

HyperNeutrino

as long as you're not doing char by char

Downgoat

@Poke do not do this intentionally it's spam

Poke

@Downgoat how is that spam

especially if i was going to newline it in the message anyway

totallyhuman

i'm still having trouble understanding the time stamp

HyperNeutrino

19:06

if I spend about 3 seconds before posting to add my next thing in my train of thought on that might work better. hopefully

Downgoat

@Poke because you're flooding the chatroom with messages that are individually meaningless when you do it intentionally

@totallyhuman which timestamp?

HyperNeutrino

@Downgoat 1994-05-16T03:00:00-04:00

Downgoat

O_o where is this from

totallyhuman

oeis

Poke

how is it any different
than someone who just adds newlines
to their messages

HyperNeutrino

19:08

It's not. It takes more lines and space than it should (sorry btw)

Downgoat

@Poke why do you do this what are you hoping to accomplish besides wasting space. But it's not?

Poke

folks seem to be easily perturbed

totallyhuman

can anybody give me a datetime format string

it ends with & which iirc means it's a literal function?

@undergroundmonorail yeah the ping noise sure is jarring

undergroundmonorail

no like i have mathematica open right now but i don't know how to evaluate the answer

like i don't know what to type in to test it with an argument

HyperNeutrino

5) sign up for ISEF or ARML and get free mathematica :3

speaking of which I should go download mathematica sometime

before the free license runs out :3 :P

Downgoat

@undergroundmonorail functionaName["input"]

undergroundmonorail

you know what? i forgot that we're allowed to not name function literals

so i wasn't assigning it to anything

what's the colon for?

Leaky Nun

@DJMcMayhem switch both sides of equality to safe one byte

@LeakyNun functional bonding, basically same as map (right bond to) (l,i,a)->a.index(l)==a

HyperNeutrino

@LeakyNun why do none of i, i€, iĐ€, i@, i@€, and i@Đ€ work?

to get the index of each element in the list, in the list

DJMcMayhem

@LeakyNun Wrong language for the task, but 30 bytes in V: Try it online!

Leaky Nun

@DJMcMayhem nice

Business Cat

What is the var for? I figured it was a strictly typed language

Phoenix

@BusinessCat It is strictly typed, but because it's immediatly followed = new HashSet<int>(), the compiler can figure out what the type should be.

Business Cat

19:54

Weird

Phoenix

I couldn't later assign s to something that isn't a HashSet<int>

DJMcMayhem

Explanation: Reverse every line. On any line followed by any number of lines, followed by the original line, change the whole line to a 0. Reverse every line. On every line that doesn't contain only a zero, change the whole line to a 1

Phoenix

Although strictly speaking, C# does have a dynamic type that causes the compiler to not check types.

And then you can do dynamic i = 0; Console.Write(i); i = "foo"; Console.Write(i); to get 0foo as the output.

totallyhuman

weiiird

Leaky Nun

@ConorO'Brien 266 bytes

Phoenix

20:01

@totallyhuman Try it online!

Note that var only works in the local scope of a function.

If for any reason you're golfing and need to declare a variable with a long type name in the scope of a class, dynamic is golfier than Dictionary<string,int>. This will likely be useful to no one.

what kinda functions would you expect from it

@totallyhuman If we say the object is named foo, at the very least support for foo[n] and for i in foo

totallyhuman

ok

actually I can add the whole slice notation support

Riker

@Downgoat you used digital ocean for your website, right?

or at least one of them

Downgoat

yes

Riker

21:13

github recommends using an ALIAS or ANAME for hosting a github pages site

but I can't figure out how to do that w/ digital ocean

is it possible?

What's wrong with CNAME?

Downgoat

@Riker use CNAME

Riker

> Unless your DNS provider supports CNAME flattening, don't create a CNAME record for your custom apex domain! Doing so may cause issues with other services, such as email, on that domain.

and I have no clue what a cname is so I was hesistant to use that

@Downgoat is it as simple as making a file called CNAME w/ some text in it?

Downgoat

CNAME = A -> B
ALIAS = A -> B, but (C -> B works)

@Riker On GH repo yea IIRC

Riker

o ok

Downgoat

21:15

AFAIK CNAME won't let you have mysite.com and www.mysite.com though

maybe you could do mysite.com -> www.mysite.com -> othersite.com

idk ¯\_(ツ)_/¯ DNS is weird

@Downgoat huh

mınxomaτ

@Downgoat Sure it does

Downgoat

@mınxomaτ well they can't point to same thing right
