The funny thing is AI is not really mentioned in the rest of the article. I don’t think any of the new technology being introduced has anything to do with AI.

I guess “AI” is just a synonym for “new stuff” now.

Ears turn out to be a good way to recognize individuals. Ear biometrics is an evolving area.

Right! They used to have a commercial airliner that broke the sound barrier.

I was confused about how the article kept saying “hypersonic” without defining it. Looks like hypersonic means 5x the speed of sound.

This thing is huge, it does 0-60 in under 3 seconds, has sharp angles, and its styling does not seem to target the sensible end of the market… It’s like an industrial strength pedestrian destroyer.

Could all YouTubers everywhere please emulate this guy’s style… no obnoxious edits, no “destroying” someone else’s point of view… he just calmly and methodically explains what he’s done and what the issues are.

I don’t think I followed a specific guide. I’m using the HifiBerry Amp2 amplifier with the Pis. The house I moved into had Bose in-wall speakers in a couple of rooms and I added some in-ceiling speakers and a couple of outdoor speakers. Most of the speaker wires are routed down to the basement, so I can have all the Pis connected right to the switch via Ethernet.

Running speaker cable is by far the hardest thing about this. You could also connect the Pis via Wi-fi; I haven’t tried that but it is supposed to work pretty well.

On the software end, it’s pretty simple. PiCorePlayer is just an image you burn to an SD card and boot up on the Pis. I run LMS in a docker container. As long as the PiCorePlayer instances and LMS are all on the same subnet, they will auto-discover each other. If they’re not, it’s just a matter of configuring the LMS server URL on the PiCorePlayers.

LMS configuration is also pretty simple… you point it at your music folder and it will scan and index your MP3s and other audio files. It has plugins for Spotify, Tidal, Youtube, and some other apps. You can control it via browser, or there are Android and iOS mobile apps.

Once you buy the Pis, amps, power supplies, and cases, you are looking at probably $140 or so per zone… so it’s not entirely cheap, but I think it’s cheaper than Sonos or other pre-built systems. It sounds great and the different Pis sync very well. I don’t hear any sync issues walking from zone to zone.

I have 6 4b’s running PiCorePlayer for home audio. I control them with LMS and can sync them or play different things in different rooms.

I’ve been running Linux on all the machines I own for years, but I still have to run Windows for work. Not everyone can just switch and I doubt there are many reading this who are unaware they could switch to Linux (or Mac, BSD, etc.).

Oh I also have one MacBook running MacOS because Apple decided to only allow iOS development and parental controls, of all things, on Apple devices running Apple software.

Yes MS and Apple suck but it’s not as simple as “just switch.”

You’re right, but you could say the same about the National Park GIS lookup.

There are involved parents who still want to use parental controls. It’s not like everyone who uses the controls is relying solely on them. It’s not an all-or-nothing proposition.

The other frustrating thing about Apple’s parental controls is that you need another Apple device to use them. Good old fashioned brand lock-in. No good reason you couldn’t manage this in a browser.
