Of course it is. It's actually a lot easier, as there are no envelopes and just one sample per instrument. Firehawk/TDA wrote this excellent player a while back: http://mod.haxor.fi/Purple_Motion/2nd_pm.s3m

Hmm, I appear to have a sample loading overflow bug somewhere... http://www.a1k0n.net/code/jsxm/#nf-chill.xm Edit: pushed a fix... something is goofy with the sample data in instrument 4.

It got renamed from JavaScriptNode to ScriptProcessor when it switched from webkitAudioContext to AudioContext, and it seems to be the best-supported way to do it. I don't see why not. But of course IE doesn't support it at all an

Funny, I just wrote one of these for the web. I don't oversample at 3.5MHz though. http://www.a1k0n.net/2015/11/09/javascript-ft2-player.html

FWIW, most of this code is actually contained inside for loop expressions, since you can chain them together with commas and get away without using any braces. Once that's done it's hard to even count "lines".

I am a big fan of viznut also, and took the liberty of translating this into Javascript so we can all hear it without trying to find a /dev/dsp analog (I used ./viznut | sox -t raw -e unsigned -b 8 -r 8000 - -d): https:&#x2F

Speaking of crazy ascii company logo animations, I never got a chance to golf these down, but I made some with color and signed distance field ray marching: https://github.com/a1k0n/asciitracing

I transformed the code into something sort of readable, although still somewhat difficult to understand: https://gist.github.com/a1k0n/15f6cc2fc9428d6fd197

I went ahead and changed the title on my site, because I am also sick of that comment.

IIRC, Piper is a reimplementation of the perforce backend, in order to handle the code size and the sheer number of "changelists" submitted per second. Nothing to do with code.google.com.

My theory is that it's also being written to the RPi's serial port console, which runs at 115200 baud by default, so 11520 characters/second or ~7ms to write 80 characters.

He even has a quadrature (as in, sine and cosine) oscillator for any frequency, using only integer adds and multiplies, which would obviate the lookup table used in this post. It's a bit like masswerk's post above, except with a

FWIW, I gave a talk about the Alternating Least Squares algorithm mentioned here (and linked in several comments) and how we implemented it at Spotify: Slides: http://www.a1k0n.net/spotify/ml-madison/ Video (for t

by a1k0n 11y ago
That's not actually true. The matrix they're talking about inverting here is actually just a square matrix of 8x8 or 128x128 (in their graphed example) to solve the alternating least squares problem, in the paper you linked. What

Or, more likely, they just use the mobile app.

And computed gotos, which just jumps to a pointer, which is a gcc extension. That's totally crazy, but sort of awesome.

I'm really confused. It appears to have no HDFS support? So how do you get data in and out of the cluster? I guess the InputFormat just takes care of that magically? Also the code isn't even close to Google style. I guess that&#x2

Take a look at how avrdude works over libusb. That's a pretty good example of bulk-upload and bulk-download and various types of things you're likely to want to do with a microcontroller.
115.
by a1k0n 12y ago
You could always just use libusb to talk to your device (e.g., an AVR w/ V-USB or another microcontroller with actual USB support) from user space, instead of fooling around with fake COM ports.

The current network hash rate is ~240e15 hashes/second (240 million gigahashes/sec). So 54282 hashes/second as a fraction of the current network hash rate is 226e-15, which would yield approximately 5.65e-12 bitcoins every 10

Definitely a plastic rivet. It's too pointy to be a bolt, and you can see the thin 'head' separated from the flange which releases it.

I didn't see this mentioned in those articles, so I figured I'd mention it: If the level has a lot of geometry, you could also make a BSP tree, and then at runtime you'd just have an O(log n) lookup, plus an O(m log m) runnin

Just because it doesn't have the ,1 doesn't mean it's written in BASIC; it could still be written in machine language with a BASIC stub that executes the actual code (which is loaded into the BASIC memory area but isn't
