Especially since the source sucks, with “gems” like > Every Apple device, including the T2 security chip, has been jailbroken with checkra1n so far. and “jailbreaking makes your device insecure”.

Jailbreaking DOES break the security model though. Its literally performed to "break the jail". It takes a locked down system and removes the locks, resulting in a system that is more open; to yourself and an attacker alike.

The fact that jailbreaks exist show that the security was broken when you got there, kind of like when you pick a house’s lock you’re not “reducing its security” unless you choose to throw away the lock entirely. You could (and many jailbreaks do) add a better lock.

Jailbreaking uses vulnerabilitities, but doesn't (by itself, of course it allows the user to) introduce any. It even allows you to patch the vulnerability behind you before Apple does officially (see JailbreakMe, 3.0 IIRC).

> Jailbreaking uses vulnerabilitities, but doesn't (by itself, of course it allows the user to) introduce any. What? The entire point of jailbreaking is to leverage specific kinds of vulnerabilities, often only exploitable via physical access (a tether and DFU mode is typical), in order to root the system so that afterwards other stuff can be done with it more conveniently. Sometimes this even necessitates further se…

Checkra1n for A11 isn’t really considered to be usable for that reason, so it’s not a very good example.

My understanding, though I'm not sure, is that a "traditional" jailbreak (installing Cydia and such) allows all apps to read/write from the full file system.

Usually, yes, but there is no need to actually do that. I would be surprised if the jailbreak presented here installs Cydia.

Jailbreaking by definition introduces avenues for exploitation against what device security requires. Apple pays millions of dollars for security staff, auditing and security research.

It might actually be billions at this point, since they bake in some features into the silicon itself. That being said, Apple’s device security model is has many places where it is not aligned with what most people want. KTRR is a good example of a mitigation that has no effect in practice for preventing most exploits, and it’s just one of the instances where Apple tries to protect their software over you, the user.

hidden 14-pin connector https://www.macrumors.com/2018/02/12/homepod-teardown-ifixit...

Has anyone removed the rubber foot and if so was it destructive?

I don’t think it is, since the HomePod needs to actually work for that connector to be useful. You may need to stick it back on to “fix” it, though.

They look like the sort of pack-in speakers you got free with a Packard Bell computer in 1993.

Not to dogpile, but do you remember the 90s? In 1993, computer hardware that wasn't SGI wasn't allowed to be any color besides Beige , to the point that in the late 90s having a black PC was a design trend instead of the default.

> computer hardware that wasn't SGI wasn't allowed to be any color besides Beige

Not true. Digital (DEC) PCs were "almost white" (maybe stightly off-white but still approaching a cream, not beige).

Hard to find a picture that shows this without having aged but this does a good job: https://www.computinghistory.org.uk/userdata/images/large/68...

Note the marked difference between the beige floppy drive and the case.

The Sonos Move has "Auto Trueplay", which is the same, and allows Bluetooth playback in a "dumb speaker" mode. Weirdly, not at the same time - Auto Trueplay is only supported in WiFi mode.

Does Sonos still spy on people? ( https://news.ycombinator.com/item?id=24680614 )

Everything is spying on us. Privacy was traded for “free” stuff.

I hope this leads to some way besides Airplay to play arbitrary audio with no delay. If Apple had just included support for Bluetooth audio (or God forbid, an aux jack) I would've bought two full-sized Homepods to use as computer speakers two months ago.

What do you mean by "no delay" ?

If you mean the delay between asking Siri to 'play music' and music to start, that is annoying and should be fixed by Apple engineers at some point. Siri is just way too slow on the Homepod. I typically use my phone and just manage what is playing that way, which is faster and has a better UI anyways.

If you mean playing something with minimal latency between your source and the speaker, that is just not going to happen with any sort of speaker over wireless. Airplay is pretty good in that regard, but you can never beat just plugging in a line out to a full fledged self powered speaker, like the KEF LS50s or LSX.

What's the trouble with buying any of the competition, if you want those features? You can get a Klipsch R51 PM for quite a bit less than the price of two HomePods. Better audio, Bluetooth, aux, optical, USB, even phono pre-amp in case you have a turntable.

I think they're (one of?) the only smart speakers on the market to automatically calibrate themselves to the room. I'm sure it's just some EQ and maybe a bit of phase adjustment, but the speaker doing it automatically for you whenever you reposition it is a nontrivial feature that makes the audio sound noticably better than much of the competition.

If you are technically inclined, this isn't that hard to do. You will need a calibrated mic, but result is you can do Sonos style adjustments to calibrate for a room on any set of speakers:

https://www.hifiberry.com/docs/hifiberryos/hifiberryos-room-...

https://www.hifiberry.com/shop/boards/hifiberry-dac-dsp/

They maintain a list of supported microphones.

You can even bake the configuration into the HifiBerry DSP once done, it doesn't need the Pi attached to apply the room correction. The included HifiBerry OS software has a setup process that makes calibrating the room with mic just as easy as the Sonos system.

I was huge into Sonos ecosystem, but recent actions with how they treated owners of earlier equipment have left me cold on it. This works forever once set, assuming you don't move the speakers. Works with any old speaker/amp combo you can output a phono/optical signal to.

its purely opinion etc, but I am just as happy with results from this system with nice pair of bookshelf speakers as I was a pair of Sonos 1s, and it will work as long as the board lasts.

I am shocked hifiberryOS hasn't found more fans, its really impressive for what it does for little money with a supported DSP. The hardest part of this is cloning an image to an SD card, rest is plug and play. You could eBay the calibration mic once done too. If you intend to move your speakers a lot this is no good of course, but my experience is people often set these things in one place in their home.

How are you using your Raspberry Pi to control your HomePod?

It's a convoluted setup I'm not sure I'd recommend to anyone else! :) Still tinkering on it, but current rig is a Respeaker Core [0] running voice2json [1], which sends MQTT commands to a Mac Mini running mopidy [2], and the audio is routed through Airfoil [3] to multiple AirPlay speakers. (In theory, a Pi could drive all that directly, using shairport [4] rather than Airfoil.) The major shortcoming is that Airfoil d…

That sounds incredible, thanks for posting. Do you not use the sync at all with that kind of lag?
