oh

I was thinking of making a new programming language

Gimme ideas...

Destructible Watermelon

I have none ._.

@DestructibleWatermelon, do you want help with language ideas? (if so, then generally speaking what kind of language do you want)

Destructible Watermelon

I was thinking maybe I would make a terse version of woefully, but that seems kinda .~.

@zyabin101 about what?

Destructible Watermelon

@Qwerp-Derp 0/10 atom is the worst

Just cool: github.com/gfredericks/quinedb

@ASCII-only Now say that to 30,697 stargazers on the Atom repo. :P

@ASCII-only Why u do dis

@zyabin101 Make that 30,698.

(I just starred it)

@Qwerp-Derp Atom takes forever to load certain things, plus it's really RAM-intensive

@Qwerp-Derp :D

Oh no

Need to do left recursion removal ;_;

How do conds work right now for multi-digit vars and stuff?

Oh

9:37 AM

@DestructibleWatermelon do you want another idea?

Destructible Watermelon

you can have your idea. I use my own ideas, thanks

@ASCII-only How do conds work for something like this cond 111 ->

Chat macro challenge:
Programming language with these qualities:

two non-intersecting command subsets (A, and B)

A and B are both TC

Any subset of A is not TC, same for B

Any set that contains: All but one of set A or B, one command of the other set, is TC

Hmm... @betseg If you won't spam in my thought room, then you should be fine.

@zyabin101 when did i spam anything

Okay :3

hey there! i've never post any question or answer in codegolf, but i love reading your code. how can you calculate the bytes the piece of code takes?

@lois6b If you use ASCII (basically no weird characters) it's just the length of the code (don't forget about newlines)

Otherwise it depends on the encoding

@flawr The “outgolfing Dennis” meme is honestly one I’d like to see fade away:

Aug 31 at 15:48, by Dennis

@LeakyNun Not my vote, but I have to say, I could do without the little victory dance every time someone outgolfs me and/or Jelly.

But it's impossible to outgolf Dennis...

Also, I can't flag posts that don't advertise a product as spam.

It’s just not very sportsmanlike, and Dennis himself sounds tired of it.

What do you think about the upside-down tent question, is it a dupe?

11:57 AM

@Lynn True. But, in my (and everyone's) defense, it's still a big achievement.

Not always, which is the point

TùxCräftîñg

back

I just wish we could (a) take our own advice of “not comparing across languages”, and (b) appreciate achievements without having to pin one person down as a benchmark ┐(￣ヘ￣)┌

Yup

I guess it's hard to appreciate that excessive praise can become tiresome until you've experienced it, so we should work harder to help people understand that.

Get a turbocharger.

Do you remember when computers had a turbo button?

I do :)

I still don't know what it actually did, but I loved pressing it.

I never knew how long it was safe to hold it down for

Oh, what a ripoff. Don't look it up. Its actual function is terribly disappointing :(

TùxCräftîñg

12:57 PM

haha it slow down the clock

Ikr, what kind of asshole calls a button that slows things down 'turbo'?

TùxCräftîñg

¯\_(ツ)_/¯

I'm sure I remember the turbo button making things run at least twice as fast

The turbo button is probably turned on by default for some. ;)

I have those vague memories too, but it could be that I just remember it backwards, or what I thought was on was actually off.

Can anyone recommend a good streaming service that can be easily programmatically streamed to? The last time I tried to stream to Twitch with ffmpeg it was a real pain

for terminal, for GUI idk

ideally I'd just like to be able to shovel video data (preferably uncompressed or encoded with an easy to use codec) into a socket and forget about it

@mınxomaτ I think I remember you mentioning a new YT stream api

If it's the one on his GH, it's for streaming MP3 audio from YT.

Yes.

Oh.

Can I do that in reverse without losing my sanity

@quartata YT live streams are not that different from Twitch.

CMC: Given a number N, yield the numbers 0 to N - 1 with k spaces in between each, where k is the previous number. E.g., for input 10, yield should be: 01 2 3 4 5 6 7 8 9.

I created a simple function that approximates the denominator of any given decimal number

It comes up with some interesting results for irrational numbers, such as 5419351/1725033 for pi

2:41 PM

Is this using continued fraction convergents?

@Sp3000 No, it's just a horribly inefficient loop: function den (x) { for (var i = 1; Math.min((x * i) % 1, 1 - (x * i) % 1) > 1e-7; i++); return i; }

:( okay :P

I'm sure continued fraction convergents would be more efficient :P

I only asked because I was wondering whether you did it because of the recent continued fractions challenge :P

No, my main goal is to write a function that deciphers whether a sequence of integers is arithmetic, geometric, recursive, etc.
