Which finger do you type C (in qwerty layout) with?

Potato44

@feersum properly, or personally?

feersum

You as in you

Potato44

left index, usually

sometimes, my left thumb

Nathan Merrill

yeah, left index for me. Never my left thumb

in fact...I don't use my left thumb for anything but hotkeys

feersum

I do the same as you guys.

I looked at a couple of tying websites and they said you should type it with the middle finger.

That seems wrong though.

Leaky Nun

5:40 AM

left index

feersum

Since for the right hand, they all agree, the fingers should move outward

As in towards the nearest edge of the keyboard.

But using middle finger would make it move inwards which seems pretty uncomfortable to me.

Potato44

I find it weird that which fingers I use to type is very dynamic, but when I play rhythm games I would like to play with dynamic finger movement, but can only play with static finger positions.

feersum

Well, do you play rhythm games every day?

Potato44

not recently, but at one point I did.

feersum

Which kind of controllers?

Potato44

5:44 AM

keyboard, specifically a Cooler Master Quick Fire TK

Also, a drawing tablet, I played osu! before my windows install borked itself.

feersum

5 typing websites I checked recommended the middle finger to type C, but 4 real people agree index finger should be used, weird.

Potato44

I never claimed I type properly, actually I know I don't.

feersum

Oh this is a regular computer keyboard

Nathan Merrill

If you are going for high-speed, I agree: you should use the middle finger

feersum

Why can't you assign letters to the notes or whatever?

Nathan Merrill

5:48 AM

the index finger is overloaded with possibilities

ATaco

I have no idea how to use C#'s Delegates, but I think it's exactly what I need right now.

Potato44

@feersum huh, what do you mean? I can do that in the keyboard based rhythm games like LR2 or osu's mania mode. But I find extremely difficult to play with dynamic finger movement, but I want to learn to do high key count modes like 14 key which require dynamic movement.

feersum

I guess it's harder if the stuff you type doesn't spell any familiar words.

Nathan Merrill

@ATaco they are first class functions. What are you stuck on?

ATaco

It's alright, I've wrapped my head around it now.

Wasn't sure how defining delegate classes(?) worked.

@feersum I guess the hard part is actually learning how to translate the onscreen patterns to patterns of movement that are actually possible without getting my fingers tangled.

@Potato44 0/10 no rhythm game should ever need more than 2 fingers

@ASCII-only All rhythm games that I can think of that are playable with 2 fingers are mobile games. or Dance Dance Revolution, which is played with the feet.

ASCII-only

@Potato44 ok. 0 fingers: osu :P

Potato44

@ASCII-only How are you going to play that without fingers. You need at least one to tap, plus however many you need to hold a mouse or tablet pen.

ASCII-only

@Potato44 hmm that's true.

but if you're using a pen then you don't need an extra one to tap

@Potato44 also it's possible with one: a touchscreen laptop

Is it possible to make call functionality for a class, like lua's __call metamethod?

C# is not a scripting language

Boring, but acceptable.

although you can probably make a class inheriting from Action/Func

Anyone have any opinions on which JavaScript based golfing language would work best for a byte-restricted KotH?

I don't know any, but am considering Japt and TeaScript.

Wondering whether to choose one, or possibly accept either.

Anything which can compile to JS is a candidate, but I'm leaning towards keeping it simple, so just one language is my current preference

ASCII-only

@trichoplax Byte-restricted?

@trichoplax Pretty sure Japt is the only one still in development

trichoplax

For example, your entry must be no more than 200 bytes of Japt

Japt was what prompted the idea, but I wanted to get an idea of what other possibilities there were

Although something not being actively developed might be more stable?

@trichoplax I don't think any are being actively developed :P

@trichoplax Through emscripten, most languages compile to JS.

ASCII-only

@wizzwizz4 but it's usually pretty slow

wizzwizz4

@ASCII-only ASM.JS is pretty fast.

trichoplax

I want something reasonably fast, and I want a reasonably small set of languages (or just 1)

I could just post a byte-limited KotH allowing only JS answers, but I like the idea of it being a golfing language

wizzwizz4

10:36 AM

@trichoplax Have some sort of generic bytecode, like JVM or Dis.

ASCII-only

@wizzwizz4 IDK. I thought the overhead of basically emulating an environment would cost quite a bit, but I guess it should be comparable to JS speed

trichoplax

@wizzwizz4 Then allow entries in any language that can output that bytecode?

wizzwizz4

@ASCII-only Emulating an environment would be a performance penalty, but on good implementations (such as Firefox) it's only ~1.5x.

@trichoplax Yes.

trichoplax

Interesting

ASCII-only

@wizzwizz4 oh, that's not bad then

wizzwizz4

10:38 AM

I recommend Dis over JVM because, although JVM is more popular, more things compile to Dis.

Well, more things can be made to compile to Dis.

feersum

Eh, I'm pretty sure wizzwizz is talking out of his you-know-where here.

wizzwizz4

@feersum JVM is stack based but Dis is register based, which means you can make LLVM work with it.

I think.

feersum

Huh? I'm referring to the various performance claims.

wizzwizz4

Never mind; LLVM converts to JVM too. You can choose either.

ASCII-only

Any language that's feasible to run on an actual computer really

ASCII-only

@wizzwizz4 Basically put things onto a stack and call functions on the stack

wizzwizz4

10:47 AM

@ASCII-only Oh. So, like Java and Python then.

Yeah, that's probably what high-level looks like.

ASCII-only

@feersum hmm, that's not exactly high level, but it should still be easy to compile machine code to said theoretical bytecode

feersum

Can you name an example of a not high level language according to your definition?

ngn

@ASCII-only cpu manifacturers these days consider x86 a high level language - they implement it in microcode

trichoplax

@dzaima Maybe I should make it a JS KotH with a byte limit, and then allow optionally using Japt or something too

ngn

@trichoplax why not plain js?

dzaima

10:52 AM

@trichoplax I don't really see the point in involving golflangs anyway - just multiply the bytecount allowed by a bit and limit to JS?

wizzwizz4

If any of you can get this page working, you've got an Internet Explorer-based emulator.

ASCII-only

@feersum I guess I worded it incorrectly :/ It should be easy to compile any language (as long as it's not just theoretical) to the bytecode easily

trichoplax

@ngn That would work - I just liked the idea of using a golfing language since I'm going to restrict the length of the competitor code

ASCII-only

@trichoplax You could just increase the length limit. As an added bonus, you're using JS, meaning no compilation and everything's fast

@dzaima There's a good chance I'll end up doing that. Keeps to my rule of keeping KotHs as simple as possible without losing whatever makes them interesting

Adám

@trichoplax Thanks, on his behalf.

ASCII-only

@feersum Probably not. On a side note, I wonder if the smaller instruction set would reduce instruction lookup times or something like that

trichoplax

@ASCII-only A big problem with Formic Functions is that several of the players create hundreds of workers each, so they get the 15ms limit hundreds of times. The idea I'm working on now has a fixed number of pieces per game so shouldn't suffer from that. I might have to keep the time limit generous to allow for golfing techniques though

@Adám A better idea would be to make refreshes automatic :P

@feersum Also I don't think any amount of reduced instructions (withing reasonable limitations) would bloat binary size by a significant amount

ATaco

Asyncronous Funky is going far too well for it's own good.

@ASCII-only Users may edit their profile many times in a row to see how it looks. No need to refresh (if it is resource intensive) until they are done.

ASCII-only

11:07 AM

@wizzwizz4 It shouldn't be computationally expensive though...

wizzwizz4

If it's updating all of the transcripts, it could be.

feersum

@ASCII-only So you're arguing that a more complex instruction set doesn't actually make the code any shorter?

wizzwizz4

I don't think there's caching there, but there might be.

Adám

If it is just a matter of resetting one's parent user, a user script could do it…

ASCII-only

@feersum It does, but e.g. 2x more instructions wouldn't make the code anywhere near 2x shorter. probably.

feersum

11:09 AM

@wizzwizz4 Do you think there is literally a copy of the profile image stored in the database for every transcript message?

ASCII-only

@Adám I guess, but it shouldn't be that resource intensive. Maybe set a limit of once every e.g. 5 mintues (starting at the first time the user changes avatar)

wizzwizz4

@feersum No, but there's probably a URL.

Come to the sandbox and I'll demo it to you.

feersum

Supposing it is implemented as a URL, one simply changes the image served by said URL.

wizzwizz4

@feersum But it's the URL to the image, I think.

feersum

Right, I'm saying today /foo.png serves a goat, then the user changes profile, and now /foo.png gives you a fish.

ASCII-only

11:11 AM

@wizzwizz4 this has the correct image

wizzwizz4

@feersum You could do it like that, but SE doesn't seem to internally.

feersum

It's much more likely that an ID would be used for the user rather than a URL.

So you don't actually need toh ave a URL that serves different images.

ASCII-only

@wizzwizz4 yeah. what it appears to do instead is something like store the image URL in a DB, then use that every time a page is generated

@NathanMerrill Yes that works for Formic Functions, since the ants have no memory (including no state for a RNG). It's implemented and makes a huge difference, although there are a huge number of possible inputs to memoise

It is just about manageable because they can see only the 3x3 grid around them. For what I'm working on now I want each player to see the whole board, so that won't be an option

@trichoplax Tbh, I think you should use WebAssembly.

hacks.mozilla.org/2017/03/why-webassembly-is-faster-than-asm-js

It's a bit irritating for those of us who still refuse to let Internet Explorer go... *sniff* but it's probably the language that best fits your criteria.

feersum

Is WASM available (as a real implementation, not one that compile to JS) in the consumer versions of major browsers now?

> not one that compile to JS

You are confusing asm.js and WASM

feersum

I am not.

I read of WASM prototypes that compiled to JS.

@wizzwizz4 I'm prepared to accept the sacrifice of irritating those using Internet Explorer if necessary

mınxomaτ

To answer your question: caniuse.com/#feat=wasm

wizzwizz4

@feersum That's for polyfills iirc.

It's ironic that caniuse.com doesn't work in very old browsers.

feersum

Why does Chrome skip from 49 to 63 in this caniuse table?

ASCII-only

@feersum For usage percentage

wizzwizz4

@feersum It's showing the more popular versions.

@feersum It doesn't. Click "show all".

ASCII-only

It's bascilally saying the majority of chrome browsers are 49+ - for the reason they chose 63 (well, probably) see the percentages of 49+ and 63

trichoplax

@wizzwizz4 I like the sound of that for speed, but it would depend on how much participation the contest would lose by using WebAssembly rather than JS

betseg

chrome's current version is 66 but caniuse shows 65 ree

ASCII-only

@trichoplax solution: write the controller in wasm, add a JS interface

wizzwizz4

@trichoplax hacks.mozilla.org/2015/12/…

You don't need to use an assembler.

@betseg well it hasn't been that long

trichoplax

@ASCII-only That sounds like it would still limit me to the speed of heavily golfed JS
