I'm thinking of making a golf language for array processing

I'll call it F♭, probably

Alex A.

implemented in F#, I presume?

Geobits

B♭ has so much more puntential, though :(

Roujo

@AlexA. Yes

@Geobits That's the second runner up

Since F# + B♭ + C# is a nice chord

Geobits

Cool. I hate to see a good pun wasted.

Roujo

And then I'll be writing B♭ code

Alex A.

11:12 PM

Wait a sec, isn't F♭ just E?

Roujo

Just like the old days

@AlexA. Yes =P

More or less, anyway

Alex A.

ಠ_ಠ

Roujo

I'm pretty sure it'd be something slightly different

Doorknob

I've seen F-flats in things I've played before. They come about for similar reasons that double-sharps and stuff exist.

Geobits

@AlexA. It's written that way in some keys IIRC. It's the same note.

Calvin's Hobbies

11:13 PM

Best name for a new programming language?

Roujo

Just like F# and G♭ are slightly different

Doorknob

@Roujo They're the same note physically, on the piano anyway.

Geobits

For every key you need to have an A-G, that's all. It leads to weird things.

Roujo

By one ninth of a tone

@Doorknob In practice, yeah. In theory, they're slightly off.

El'endia Starman

@Calvin'sHobbies I voted for the Jelly one. It's hilarious. :P

Roujo

11:14 PM

IIRC, tones are separated by 9 intervals

F# is F + 5 intervals

quartata

@Doorknob F-flats and C-flats are very common in key signatures where B or E are flat and you don't want to use a natural (which makes the key natural for the whole measure)

Roujo

G♭ is G minus 5 intervals

Geobits

I've never heard of that kind of interval o_O

Roujo

However, yeah, that never comes up in practice because that'd lead to absurd instruments

Musical temperament

In musical tuning, a temperament is a system of tuning which slightly compromises the pure intervals of just intonation in order to meet other requirements of the system. Most instruments in modern Western music are tuned in the equal temperament system. "Tempering is the process of altering the size of an interval by making it narrower or wider than pure. A temperament is any plan that describes the adjustments to the sizes of some or all of the twelve fifth intervals in the circle of fifths so that they accommodate pure octaves and produce certain sizes of major thirds." Temperament is especially...

Doorknob

@Roujo So, say, F# on most instruments is just F plus 4.5 thingies?

@quartata avodad

Roujo

@Doorknob Yup. Technically off, but it's the best compromise and you won't hear the difference =P

quartata

Musical temperament is actually really interesting

Roujo

I'm just going by memory, mind you - my brother gave me a summary of his music theory courses back when he had them

quartata

11:17 PM

If you ever have access to an actual piano (not a keyboard), try holding down C (without it making noise) and hitting the next G

You'll notice something ;)

Roujo

@quartata Dah, I was in front of one just an hour ago =P

I'll try to remember it ^^

Geobits

I had to get rid of my piano years ago. It was made in 1908 and I couldn't take it with me :(

quartata

You'll hear the C ring

Thomas Kwa

There are lots of different temperaments.

RikerW

Nobody hear actually plays piano but me, huh?

Thomas Kwa

The ninths of a tone thing is just a closer approximation to integer ratios than 12-TET, but it's still an approximation.

ӍѲꝆΛҐӍΛПҒЦꝆ

@RikerW I play piano. And saxophone (alto and soprano).

And I have absolute pitch (no bragging :))

Roujo

@RikerW I play. Plus a bit of guitar, plus the recorder ^^

Thomas Kwa

@ӍѲꝆΛҐӍΛПҒЦꝆ You can't score like that.

Geobits

@RikerW IIRC PhiNotPi does. I know he composes, and I think he plays, too.

Thomas Kwa

11:20 PM

@ӍѲꝆΛҐӍΛПҒЦꝆ What pitch am I thinking of?

quartata

@RikerW I've played it for years

Roujo

@ӍѲꝆΛҐӍΛПҒЦꝆ Wow, that's awesome. I have good pitch memory, but no absolute pitch =)

Geobits

I used to play piano, but would be quite rusty now.

RikerW

@ӍѲꝆΛҐӍΛПҒЦꝆ Good, cause I suck badly.

@Geobits I think he only plays clarinet?

ӍѲꝆΛҐӍΛПҒЦꝆ

@ThomasKwa B sharp :)

Geobits

11:20 PM

I'm better on guitar, and can play tin whistle reasonably well.

RikerW

@ӍѲꝆΛҐӍΛПҒЦꝆ lol

@ThomasKwa Wait why not?

@ӍѲꝆΛҐӍΛПҒЦꝆ because the encoding doesn't exist yet

Roujo

@PhiNotPi Nice. We know! =P

It is okay.

Thomas Kwa

@ӍѲꝆΛҐӍΛПҒЦꝆ Nope, A natural.

whispers I think @ӍѲꝆΛҐӍΛПҒЦꝆ doesn't really have absolute pitch

ӍѲꝆΛҐӍΛПҒЦꝆ

@ThomasKwa Dangit. Just a note and a half off!

Okay I fixed the encoding thingy.

RikerW

Good.

Alex A.

I understand.

quartata

11:28 PM

Hey @ӍѲꝆΛҐӍΛПҒЦꝆ does ESMin have a safe mode?

Alex A.

It only lives dangerously

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@AlexA. get a sane browser.

Doorknob

@ӍѲꝆΛҐӍΛПҒЦꝆ maybe you should make your languages have regular names then :P

ӍѲꝆΛҐӍΛПҒЦꝆ

@quartata pssh who needs that? :)

Anyway, no it doesn't.

RikerW

@CᴏɴᴏʀO'Bʀɪᴇɴ Yeah, like chrome.

But ok

ӍѲꝆΛҐӍΛПҒЦꝆ

11:31 PM

Oic

That would be sorta nice...

quartata

.....if I told you Japt is in Databot would that motivate you to make a safe mode?

You can't let Japt beat you

ӍѲꝆΛҐӍΛПҒЦꝆ

@quartata Lolwow. Of course not!

quartata

Oh.

ӍѲꝆΛҐӍΛПҒЦꝆ

Wait -- why do you even need safe mode?

quartata

Because we don't want people evaluating JS and reading our files

ӍѲꝆΛҐӍΛПҒЦꝆ

11:32 PM

Or perhaps, how do I implement it?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@ӍѲꝆΛҐӍΛПҒЦꝆ That was pretty much my reaction when prompted to make a safe mode for Jolf.

Alex A.

@ӍѲꝆΛҐӍΛПҒЦꝆ To avoid unwanted language pregnancies

ӍѲꝆΛҐӍΛПҒЦꝆ

@AlexA. ESMin is sterile tho

quartata

Disable any form of eval or raw JS support, and any way of accessing the internet

Alex A.

...oh

ӍѲꝆΛҐӍΛПҒЦꝆ

11:32 PM

Clean code amirite

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Downgoat could you add Simplex under CP 1252 encoding?

ӍѲꝆΛҐӍΛПҒЦꝆ

@quartata Oh... That will be superbly difficult.

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ Simplex?

ok

quartata

@ӍѲꝆΛҐӍΛПҒЦꝆ Really?

Oh.

ӍѲꝆΛҐӍΛПҒЦꝆ

Um... you see, ESMin is highly dependent on the internet.

quartata

11:33 PM

Well then don't bother

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Downgoat Thanks!

quartata

@ӍѲꝆΛҐӍΛПҒЦꝆ Wait, why?

ӍѲꝆΛҐӍΛПҒЦꝆ

All the libraries and stuff.

quartata

Oh that's OK. We'll download those and add them in manually

We already pretty much hacked Japt to bits getting shoco working.

ӍѲꝆΛҐӍΛПҒЦꝆ

Oh okay. Also, eval is used in the interpreter itself...

And it's aliased.

Is that just taken out?

quartata

11:35 PM

We just need to make sure that there's no way for malicious code to do a call to eval

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ is it stylized CP-1252 or just CP 1252?

quartata

So no commands that run code and make sure that if you use eval in parsing or whatever there's no potential for a code injection

ӍѲꝆΛҐӍΛПҒЦꝆ

Okay.

I have no idea if that's the case with ESMin.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Downgoat I have no idea.

Cyoce

El'endia Starman

ӍѲꝆΛҐӍΛПҒЦꝆ

Aww yeh

You on the Bowl too?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Cyoce I like read.

quartata

Basically just make sure of the following: there's no way to call eval from within an ESMin program and that any calls your interpreter makes to eval use stringify to escape anything nasty

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@ӍѲꝆΛҐӍΛПҒЦꝆ I only watched the cool introduction thing

quartata

JS has stringify right

Cᴏɴᴏʀ O'Bʀɪᴇɴ

It escapes nasty stuff right?
