Here's an in-development audio framework which uses JS. I haven't used it, but it looks interesting.

This looks similar to https://www.wickeditor.com/#/ , at least in it's current form.

cmrdsprklpnyon The humble water heater could be the savior of our energy infrastructure woes

There's a local university that uses this method to cool their musical performance space, which causes it to be comfortably cold but without the noise of AC.

JUCE also has this kind of layout.

cmrdsprklpnyon Abolish High School (2015)

I think it depends on the school. I've personally had a very positive high school experience in the U.S.

wickeditor.com is trying to fill this niche, still pretty young but under active development.

cmrdsprklpnyon Merge tag 'arm-Apple-M1-5.13' of Linux

I don't think this works with 2019 or later Intel Macbooks, but as far as I know the most recent relevant information and drivers are here: https://github.com/roadrunner2/macbook12-spi-driver. In my own experience, it's the trackpad, keyboard, and built-in speakers that don't work, but everything else seemed to be fine (2015 macbook).

Edit: this driver got the keyboard and trackpad to work, but the microphone, speakers, and webcam did not work. I also needed to downgrade to an older kernel (4.14) to get storage to work. All external things worked fine even through a hub, and the headphone jack also worked fine.

cmrdsprklpnyon Metakovan, the mystery Beeple art buyer, and his NFT/DeFi scheme

If the artist is themself selling the art as an NFT, I believe so.

cmrdsprklpnyon I want a computer that I own

I’ve had the experience that often weird bugs pop up when signing; often it isn’t that simple unfortunately.

cmrdsprklpnyon Ask HN: Do you create music? let's hear it

I write contemporary classical music, and am applying to some highly-regarded conservatories (I enter college this year). I've made it past the prescreens and done all the interviews, so now it's just a matter of waiting and seeing what happens!

cmrdsprklpnyon Researchers observe stationary Hawking radiation in an analog black hole

I was confused as to how the researchers created a black hole in a lab, which I hadn't heard of being done before. As far as I can tell, an "analog" black hole is different from a normal black hole in that it doesn't use gravity and only works on acoustic waves or electromagnetic waves, depending on the type [1]. That said I don't really get what's going on.

I'd be curious if someone who actually knows what they're talking about could try to clarify how the researchers have a black hole here.

EDIT: There's a link[2] to another article at the bottom that describes how the researchers are simulating a black hole. My bad for not catching this earlier.

cmrdsprklpnyon Octave Compass

This is pretty nice! Something interesting to note is that it seems to use Shepard tones[1] or something similar so that the scale can be played continuously while still staying in range.

cmrdsprklpnyon I Think Beethoven Encoded His Deafness in His Music

https://tobyrush.com/theorypages/pdf/en-us/the-whole-enchila...

This covers most Classical theory in a pretty clear way, it’s cheesy but does a good job. We used this more than the textbook in a music theory class. Jazz and contemporary theory gets a little more fun, but this is a really good place to start.

cmrdsprklpnyon The end arrives as Adobe starts blocking Flash content

Is the projector going to stop working soon too, or is it being treated differently from the browser plugin?

cmrdsprklpnyon Kivy: Cross-Platform Python Framework for UI Development

I have an app, metro.drone [1], on the App and Google Play stores that I created with LÖVE2D. While I haven’t seen many other examples, I’ve seen a lot more cross-platform game engines than UI-explicit engines, many of which have (at least limited) GUI capability. I’m relatively new to programming so part of what attracted me to LÖVE2D instead of something else was the simplicity and modularity; LÖVE2D-compatible packages existed for exactly what I needed with metro.drone. I’ve come to the broad conclusion that it’s more about choosing the right ecosystem for a project than the right ui toolkit; I was originally going to use Elm but it didn’t have a good synth library.

I should again recap that I’m a novice programmer, so this should be considered more a description of my thought process than advice. :)

cmrdsprklpnyon Kivy: Cross-Platform Python Framework for UI Development

I'm a hobbyist and I've been looking into these kinds of projects for a while. From my (limited) experience, the easiest way to go for a lot of cases is just to use a cross-platform game engine's UI capabilities, but there's some other interesting not-well-known stuff like HaxeUI and LambdaNative.

cmrdsprklpnyon Pianists for Alternatively Sized Keyboards

Not exactly the same, but melodicas (and accordions I think) have smaller keyboards than standard pianos... I feel like if smaller keyboards were going to take off for people with small hands, they probably already would have by now(...?)

cmrdsprklpnyon Admitting That Functional Programming Can Be Awkward (2007)

My understanding (which there's a good chance is incorrect) is that all code written in Elm has to be in a functional style because the language strictly enforces it; but this enforcement doesn't exist in Lisp and OCaml, so they can be used to write imperative or object-oriented code, as happened in the cases described.

Lots of audio software has a similar model, Bitwig and Reaper come to mind.

cmrdsprklpnyon Structure and Interpretation of Computer Programs (SICP) Book

How to Design Programs (https://htdp.org/) is fantastic, I believe it's based off SICP but I found it a little more accessible. It leads into recursion pretty well and intuitively, probably the favorite programming book I've read.

cmrdsprklpnyon Structure and Interpretation of Computer Programs (SICP) Book

I've read it; it's a phenomenal book to understand more about how computers work on a hardware and conceptual level, but it doesn't really teach programming. Still strongly recommended.

cmrdsprklpnyon Teaching GPT-3 to Identify Nonsense

How do you get access to GPT-3? Is there a way besides signing up for the openai api?

cmrdsprklpnyon Metro.drone, a music practice app created by a 16-year-old

Hello! I created metro.drone, a music practice app available on the App Store and Google Play Store. Basically, it plays a drone note to a metronome beat, but I recently updated it with some features like chord building. Any and all feedback is greatly appreciated, and if there's any questions, feel free to let me know! Thank you!

cmrdsprklpnyon JazzKeys: Type to improvise Jazz music

This might be intentional on your part, but it seems to mark enharmonic equivalents as incorrect (a 5th from Gb is Db, which is the same as C# but C# is marked as incorrect).
