How huge is the latency? It's using Elk Audio OS, claiming 1ms roundtrip. I doubt this usage gets that low but I wouldn't be surprised if it was doing alright


If you're curious what categories they fit into here's Wikipedia's list https://en.wikipedia.org/wiki/WHO_Model_List_of_Essential_Me...


Xiaomi has hit 480hz touch sampling with the Mi 11. It looks possible in hardware and in software, someone just has to manage to perfect both in the same phone


One nice thing is that in brewing it can be used to generate heat for boiling during brewing rather than converting to electricity first. They mention a furnace but not a generator. 81% of Dutch power is fossil fuel based, if you have an environmental concern about that and it's good press why not.


Another playlist migration service is https://soundiiz.com/

I've been really happy with it. They haven't implemented any restrictions around exporting from Spotify yet. Might be helpful if you'd like to jump ship


I don't see Spotify on that page.


Hm right. I am fairly sure it was on the homepage. It's still inside the app and I managed to do a transfer out no worries. I would guess they are in the process of removing it? https://soundiiz.com/tutorial/spotify-to-apple-music


Maybe I'm missing something but how is the image so clear? CDs don't have a mirror like surface, they reflect light in unusual ways


The rather shallow angle probably helps a lot. On top of that the camera probably has some form of auto white balance which will counteract the tint the CD will give to the image.

Here's a quick proof of concept using a random CD and my phone's camera: https://svkt.org/~simias/up/20200914-000627_psx-cd-reflectio...

Note that the color of the reflection is not much different from a normal picture (visible at the bottom). For added difficulty I used an original PlayStation disc, that's dyed black: https://svkt.org/~simias/up/20200914-000836_psx-cd.jpeg


It's very HN that we've been trolled into debating the irrefutable, widely-known, totally obvious fact that a CD reflects light.


Didn't mean to come across as a troll, this is how I remember CDs, with rainbow diffraction. https://www.google.com/search?tbm=isch&q=cd


I think at such shallow angles it's the plastic surface that becomes reflective, not the metal layer with the pits and grooves. Hence the lack of diffraction (and hence why it works with my black PSX disc).


She's using a CD-RW with blue/purple dye. The reflection is definitely coming off the surface.


Everything reflects light, but not everything reflects it clear enough to read documents through. I haven't held a CD in ages, so it it's possible that folks don't remember exactly how reflective they are. ¯\_(ツ)_/¯


Almost everything reflects light. The discussion is on why it can be used as a mirror.


The quarter helping to hold down the CD may also contribute by blocking overhead inbound interference.


Use a pressed CD (which are good mirrors at this angle), not a blank CD (which are tinted).


I just pointed a CD at my face and it's pretty much a mirror. What unusual reflection did you expect?


Some rainbow diffraction I guess. It has been a long time since I've used a CD https://www.google.com/search?tbm=isch&q=cd


Real CDs don't look like clip art CDs. 90% of the images for "mirror" don't have reflections either.


Well I noticed it's a CD-RW which is a peculiar device, so maybe it doesn't reflect the same as normal CDs.


I think you probably haven't played around with CDs more than just to play them.


I also don't really get it. Looks too clear and sharp for a CD reflection.


Nintendo back in 2001 came out with the e-Reader that would plug into a Gameboy Advance and read cards with data printed on them. You'd have to scan a few "stripes" of data, but it there were several NES games that you could run if you had the right cards. The cards held the data for the games, rather than them being already on the cartridge https://en.wikipedia.org/wiki/Nintendo_e-Reader


I was always gutted that thing never came out in Europe. I had tons of Pokémon cards with the stripes and nothing to use them with.


Reminds me of Chef Watson, the recipes and directions that generated were supposed to be plausible https://www.welcome.ai/tech/food/ibm-chef-watson

It's not really doable from what I've been seeing. The animals grow to big and living conditions worsen


It's a little bit of an ordeal - you have to request a bootloader unlock and then wait two weeks. But doable.
