platonic ideal of supercar imo

What’s your sign?

Idk I melted one of them a few months ago, on an underclocked 160W GPU of all things

My condolences pal, not a good place for the brain to be.

Getting there myself tbh. Too tired. Too much stuff.

Is that the Waverley? Beautiful ship.

Wow

Because there are some cool people here who do cool things. Sometimes I know those people and would see the cool things anyway, but sometimes I need other cool people I know who see the cool things to share them around so I can see them.

And it's cool that they can do that.

Check out this goofy little @nanoraptor.danamania.com-looking thing. Apparently it’s a Japan-only line called the “Let’s Note” which is a name almost wonky enough to suit the machine.

I love it.

One of my fav things here is that (at least on the web app) I don’t get notifications. It obv has a notifications page, but it doesn’t try to alert me or even light the icon up. So I check my notifications on my own terms.

Much nicer than the constant attention-begging in a lot of other sites.

Where do not-normal but also not-industry people get categorised? I think I’m deep in some niche, I just don’t know which!

And they’re good video essays! I think you’re the only channel I try to not miss an upload on, which is probably impressive given I have almost no interest in movies.

This whole thread sounds like really good answers I can give next time someone asks me whether I’m gonna try monetising the next part I try reproducing for my old cars. Because I suck at mechanical design and hardware engineering and production engineering, and if I tried I’d only piss people off!

Food pic to explain where you’re from

This is a comparison people keep making, and I keep loving it

Losing the bits of the frequency spectrum that we literally cannot see isn't what hurts, it's the discarding of data _inside_ the range we can see, discarding that's vital to lossy compression algorithms, that hurts.

See also: RAW photos - they have no IR or UV in them but look great.

Actually I just thought of a useful analogy.

"Chopping off <20Hz and >20kHz shouldn't hurt quality, but does" and then pointing at 128kbps MP3 is the audio equivalent of "Chopping off ultraviolet and infra-red shouldn't hurt a photograph, but does" and pointing at a low-quality JPEG.

(sorry for infodumping, I'm just a huge nerd and stuff like this is - to me - like giving a pig a great big pile of mud to swim in)

And then ofc you can take your compressed (still analogue!) representation of the audio and digitise it (which is still lossless, though working with a crappy, exhausting waveform) and then do the equivalent of jpegging it. Which also sucks.

But that's not digital's fault.

So you can take the higher-frequency tones and crank their amplitude to levels which would cause needles on vinyl to bounce out of the groove or otherwise become unplayable.

This makes music physically tiring to listen to as the sound is always loud, there's no quiet in which the kick can seem loud

Like for a start you get dynamic range compression, which is super common on versions of media that are intended to be stored digitally as you don't have slew rate limitations like those which are imposed by mechanical systems like the needle in a record deck.

I mean if you bring compression into it, everything goes out the window. Lossy compression does degrade audio quality, but the digital sampling process and lossless compressions of that digital representation are both _provably_ perfectly lossless.

Compression is a whole other can of worms.

Yeah I 100% vibe with this way of thinking about it. Cooking is fun, when you have the time and energy and whatnot, and it would be really nice to be freed from HAVING to cook and instead be able to cook whenever I like. Even better if I don’t have to source ingredients!

(There’s an easy but useless answer, which is that the low pass filter is itself an artifact. But since we can only hear up to 20KHz and we tend to filter music for digital sampling at 22-24KHz or more, that’s not an issue even allowing for the roll-off curves common in real filters)

This is completely untrue. Shannon-Nyquist theorem describes the mechanics in detail.

If you low-pass filter the signal and sample at twice or more the frequency of your low pass, you can fully and perfectly reconstruct the original input.

Hello, I’m Cwis :)

You may remember me from such shenanigans as “two guys build a car from scratch in their driveway” and “local programmer forgets he’s not an electronic engineer”

Could be like people who prefer music on vinyl, or CRT screens for retro gaming.

Could just be that “real” food is worse, but in charming ways.
