I'm glad that's still the attitude.

In my first job we had a HeaP flatbed plotters (remember them?). Twice it failed just before an exhibition. Twice HP saved the day by loaning one to us.

Mind you, you could always have 3* the number of Rigols, so that when one breaks, you just slide it into the oubliette.

This isn’t biometric ID as such and it doesn’t leave the device’s HSP.

It’s a secondary authentication check on a hardware keychain. Think TPM or HSP type stuff. You still have to unlock the keychain with the primary auth first which is a password. This is kept open in a session.

An analogy. If you’re sitting at a Unix machine with ssh-agent running, you added your private key to the keychain and entered the password. After that you can ssh to anything with authorized_keys set up properly using PKI. The sensors on the iPhone require secondary auth for some classes of event at which point the HSP talks to the sensors and carries out a quick “is this bd139?” Check. Periodically (configurable) the HSP drops all keys and if like whack the power button 5 times or power cycle it. It’s another layer and that is it.

HSP carries the encryption keys for storage etc as well btw which is on by default.

The biometric data has three operations: write (which requires a validation first), validation, burn everything and that’s it. This is hardware mandated.

When you make a transaction you’re only allowing the transaction to be signed by the HSP’s default private key for Apple Pay which is per card.

Ergo it’s layered security with boundary checks.

Sure it’s not perfect and I openly admit that but it sits there on the fence between security and usability. Usable security has more customers and benefits than other kinds generally.

Mine is set to drop keys every 30 minutes as that stops people getting pissed off when I hit a ticket gate :D

It’s why I bought the Keysight DMM. Risk assessment said I might poke it in the mains and kill myself so I picked a good one. I have a quite strict purchasing criteria for items. Rigol only got the deal here because the failure penalty is low for me versus the ROI.

I do remember HP plotters actually. I had to argue with one and an HP/UX box running ME10 on the first IT job I had. Didn’t take a lot of work. Lovely watching them do their thing.

Not a bad idea with the rigols. My local radio shop have a couple of 300MHz units. Probably same approach. A lot cheaper than a 300MHz Keysight unit.

What Apple is selling is convenience and TIME; time YOU don't spend figuring it out, time you don't spend fixing it if it breaks, time you don't spend arguing with customer support. All you have to do is fit your needs within the confines of their ecology, and give them boatloads of money. In return, they constantly revise their ecology to fit more and more of the people with money, so eventually you will get more and more functionality from them.

Honestly, it's not that bad a deal, unless you are one of those people who just HAS to do it for yourself; then you're well and truly boned.

Time is your most valuable commodity; the one thing you can't make or buy more of. Trading mere money for more time is a deal that's ALWAYS in YOUR favor.

That's the picture that's always painted, but it's overly romantic. Apple stuff works and breaks the same way all the other crap does.

It does break. Everything breaks. What happens when it breaks is the thing. They send me a new one, i provision it and send the old one back. No downtime. If I need one now I just walk into an Apple store and sortedin under an hour.

Motorola: bye bye phone for a month and what comes back? Oh the original phone saying it was water damaged which the repairer did so they didn’t have to foot the bill.

That says that the tips need re-activating, activater will be included, WTF is that all about, security going to far now??

99% positive it's this stuff; the outer shell of the MX tips is iron, just like any other. This stuff will "re-activate" a dog turd so it's nice & shiny silver, if you can get it hot enough.  :-DD

I'm not in the mood for an extended discussion and I know I'm not going to change your mind, but every manufacturer has the same horror stories. There's plenty of horror stories for Apple, just like there are for pretty much any other. Those aren't a few exception either. There's some weird and infuriating shit going on.

Life is mostly weird and infuriating shit going on :)

Talking of which, why the hell is ebay still dead. Is everyone on holiday?
