I think a squat format like 4:5 would be much more practical than 9:16 or whatever most phones are. It's unfortunate that's the format that's come to dominate, especially when you consider the rise of vertical video.

If anyone is curious about applications - these can be used to approximate low-frequency components of a point's surroundings. They were used in Halo 3 to do real-time HDRI lighting and shadowing (see "Lighting and Material of Halo 3" from Siggraph 2008).

After the success of this method, there was a fairly long stretch of researchers looking for a better orthonormal basis (such as 2D Haar wavelents, as spherical harmonics is basically a Fourier Transform on a spherical basis). I think the pinnacle of this direction was Anisotropic Spherical Gaussians from 2013.

These days though, you'd at least use a neural net to learn a basis (or use a neural net to learn something else entirely). And of course, Gaussian Splats are the technique du jour for realtime relighting.

The vector version of these is used in antenna theory to represent and transform the radiation of finite sources, like when measuring antenna patterns.

For people who are more involved in this world than me: What're the chances of actually getting a supported full feature parity version of guile emacs? Like not anytime soon but, say, in the next 10 years.

It's my understanding it would be a significant speed improvement but the amount of work and the - ahem - stallman factor are big roadblocks.

lloda · 9 months ago
The biggest roadblocks are 1) lack of continued effort and 2) reticence on the Emacs side. I'd say 1) is the most important by far.

Learn to write upside down, then turn the paper upside down and write from right to left.

I've seen left handed people tilt the paper 90° and write more or less downwards. Their writing looked fine.

The other day I got a call from my bank, thought it was probably a scam. I hung up and tried calling back but it was a labyrinth of menu options, I gave up. Turned out that the first call was legit and I spent another day playing phone tag to get back to him.

There needs to be a better way to verify.

My bank's app has a built in messaging system, but they seem to hate using it themselves. When they want to contact me they always call, or they send me paper letters. If I contact them through the app, they don't reply there but call me about it. It's bizarre.

The latency is too high for me using the wireless Mac display on Vision Pro. Would be a lot better if we could use that wire...maybe it's possible?
lloda · 2 years ago
Apple sells a wire. It's $300.

New? Isn't this AMD's reference BLAS implementation?
lloda · 2 years ago
BLIS is a different library from BLAS, with a better API. For example when you pass an array, you can pass independent strides for all axes, and you can give independent transpose/conjugate flags. It does have a BLAS compatibility interface.

The interface isn't perfect though. For example they didn't commit to supporting zero strides. That used to work anyway, but it's broken now for some archs.

I don't remember them being that washed out.

Were they really that washed out or is it that whatever emulator they're using isn't doing the CRT colorspace and filtering conversion correctly?

lloda · 2 years ago
if you compare the c64 palette to other ~16 color computers of the era, the c64 has a definite brownish/purplish tint to it, i don't think the video misrepresents it.

>this is actually 4×4 if you're counting pixels needed on the output device instead of rom space needed

What do you mean by this? Each character requires only a 3x3 grid of pixels to draw.

lloda · 2 years ago
in the text modes of old computers, there isn't anything to separate one character from those next to it, so that space has to be in the character itself.
