Conor O'Brien

@ASCII-only I was going to ask you to help me debug something but I think I got it

ASCII-only

@ConorO'Brien Why are you using Ruby 0/10

Conor O'Brien

@ASCII-only because JS is masochism when dealing with STDIN

TuxCopter

12:21

@ASCII-only ಠ_ಠ

Conor O'Brien

and ruby is great what are you talking about

TuxCopter

ruby is bset langauge

ASCII-only

@ConorO'Brien No it isn't, that's what npm is for

Conor O'Brien

@LuisMendo Oh, I see. That's cool!

@ASCII-only I use npm. and other than STDIN, ruby's stdlib is much more plentiful, has a nicer syntax concerning ranges and slices, has great idiomatic expressions, among other things. These are perfect for a golfing language implementation

TuxCopter

Yep

ASCII-only

12:24

@ConorO'Brien Oh fair enough

Conor O'Brien

I use ruby pretty much solely for language implementation. JS is great. I'm still waiting for a nice stdlib expansion tho.

ASCII-only

@ConorO'Brien For JS? Not gonna happen IMO

Conor O'Brien

yeah well I can dream

or maybe start cracking on my own lib

ASCII-only

No just petition Ecma :P

@ConorO'Brien I don't imagine that's going to be very fast

TuxCopter

Why?

Conor O'Brien

12:27

because it's written in JS

Most Node's stdlib is wrote in JS

Should only happen if a lot of the upvotes were for the same person

TuxCopter

If it happen without serial upvoting, it's probably a bug

Conor O'Brien

weird. because I just revisited the asterisk grid problem and I had upvoted a few of the answers but not the question itself. ¯\_(ツ)_/¯

trichoplax

12:31

Some people are prolific and answer a large number of challenges in a short space of time, so upvoting their posts naturally might be accidentally detected as serial voting

Conor O'Brien

true

trichoplax

Oh. That's different. Unless that person has posted a lot of challenges in quick succession?

You can see your upvotes on your profile if you want to check

Ubuntu (/ʊˈbuːntʊ/ uu-BOON-tuu; Zulu pronunciation: [ùɓúntʼú]) is a Nguni Bantu term roughly translating to "human kindness".

In Southern Africa, it has come to be used as a term for a kind of humanist philosophy, ethic, or ideology, also known as Ubuntuism or Hunhuism (the latter after the corresponding Shona term) propagated in the...

It'd be slightly better as far as challenge similarity goes, but personally I don't find the extensions particularly interesting. Also, what's buffer for Developerz?

14:08

@Shebang I'm a little confused how "input provided at runtime" works - if I've got an infinite printing loop and I keep feeding it more input as it runs, do the sleep times get longer? Or does input happen at the start and you use that for the execution?

But in any case I don't really see the appeal of the extensions, so I might leave it for others to comment

74 digits seems reasonably high enough that you couldn't bruteforce it in any reasonable time which means you need to have a large amount of knowledge

If you assume the drive lasts for 5 years, that's 56GB of data written per day, every day.

But I don't think I could do less than 750GB, 1TB has been real nice to have

You guys don't write more than 50GB/day? Why even have computers then?

@TimmyD I honestly wonder if that was deliberate or not

Geobits

@Shebang I'd rather pay less for a smaller one, tbh. Bulk media (which is the majority of my space used) can go on any HDD, since read/write speed really isn't an issue at all for that.
