What's to stop Apple immediately releasing an update which 1. installs new keys, and 2. revokes the keys in possession of the FBI? i.e. before the FBI has enough time to modify and release their own version?
"Install this update NOW before law enforcement gets access to your phone?"
Or am I missing something?
If that's a feasible option, they're probably working on it right now.
The government justifies keeping some information secret - "operational matters", and so on. I entirely agree, in principle - you don't publish details of an impending strike against bad guys (justification of that strike being a separate matter) - but *they* get to decide to keep secrets. "They" being people in government service - someone, or some people, get to decide that their information is too precious/sensitive to reveal, and we the people generally support that course of action, because we have Freedom of Information legislation to keep the exercise of that power in check - in theory, at least.
Fine. In that case, *I* get to decide which of my information is too precious/sensitive to reveal, so suck it up. You want to keep secrets, OK. So do I, and I'm smart enough to NOT keep them on computer storage.
I do like this new model of distributed key-signing.
Indeed. Ever read the fine print on a radiator core replacement warranty? It's usually something about "warranty doesn't apply to electrolytic corrosion in the presence of 50 milliamps or greater".
That's right. Try this test - unscrew the radiator cap, start the car, get out your multimeter, set it to a milliamp range up to 200 mA, put one probe in the coolant, and the other on the engine block. I had a warranty knockback on a replacement core because it developed pinholes within 6 months. I researched it, tested the amount of current, and went back to the installer. He got the deer-in-the-headlights look when I asked him if he had tested the current. It took a bit of arguing, but I got it all sorted.
If by "inertia" you mean "I've invested a lot of time and money on hardware and software that meets my needs, and sure, there are Mac equivalents (but not GNU/Linux), so why would I want to spend more time and money to buy over-priced hardware, an operating system that has its own problems, and application software that I'll have to buy again?"
It's not just learning something else, it's the the cost, and the downtime.
When people ask me whether to buy windows or mac, I ask them what do they want to do, then I give them advice about the pros and cons of each platform - price, features, reliability, etc - and let them make up their own mind.
Someone upthread posted that the hardware ID is actually burned (for want of a better word) into the chip during manufacture, and as the phone and the CPU will have their own serial numbers, then such records would be kept, e.g. Phone serial # abc123 has CPU serial # xzy789, with hardware ID abck4e5ur789. I can't imagine why they *wouldn't* keep such information - you'd need it to verify authenticity, warranty, or ownership for some examples. Someone brings an iphone into an Apple store to repair a cracked screen, do you think they're *not* going to check it against the serial numbers of known stolen phones? Or check that it's not a brumby, i.e. some dodgy repairer has substituted the guts of one phone into the enclosure of another, thus presenting a mismatch of serial numbers?
Tell that to the people trying get out of Sydney during the cafe siege.
Uber's pricing responds to demand - it may be pre-programmed for known peaks, but it's also flexible enough to respond to conditions - although the surge during the Sydney siege was perhaps immoral, it was just the pricing algorithm doing its job, responding to a random increase in demand.
I feel quite sad about IBM. I was a junior admin when we bought a System/36, then the Senior Admin when we upgraded to an AS400.
The gear was expensive, sure, but it was good quality, the sales staff, the CSRs and PSRs knew what they were talking about, they were passionate to find a solution for you, they were friendly and reachable (not arrogant, just *competent* in the best sense of that word), and you generally got a free extended lunch or an invite to the customers' xmas drinks every year. I mean, we even had a tech team once bring an OSCILLOSCOPE to our location to pin down a problem with a machine.
I miss those days. I wonder what's happened to their mid-range teams?
Well, it works faster in a Debian VM under Windows 7, than it does in Windows 7. Mind you, I'm not usually looking for high compression - it's mostly the other way 'round, extracting poorly-encoded, over-compressed MKV files back to usable MP4.
It's comparable with Premiere Pro/Media Encoder when encoding.
This is what I don't understand. Cancer develops, becomes a life-threatening/metastatic tumour because one or more mutated cells have managed to avoid or fool numerous detection and termination processes in a particular individual. I may be more likely to develop a cancer of a particular type because a relative has had it - but that implies a susceptibility because of very similar DNA (for want of a better term - and my GP tells me that the non-hodgkins lymphoma that killed my mother is NOT one of the genetically likely types), or because northern european/irish types have a particular susceptibility to a particular type/s of cancer. I *might* be likely to transmit a mutated cell, leading to a tumour, to a person of similar genotype (for want of a better word) , but as I'm a fair-skinned northern european/irish type, how could my 'fooled' immune system be similar enough to be similar enough to anyone outside my genetic "region"? e.g. asian, african, even southern european.
Don't sweat it. When an AC uses phrases like "how little you understand x", it's kind of self-explanatory. Mom's basement comes to mind. Your theory is cromulent.
Eh? Not sure of the point you're trying to make. Were you attempting to address any of the things I said, or are you upset that some people don't agree with your viewpoint?
It's doable, technologically speaking. The minerals (in my case, lead, but also true for rare earths) are recycleable once they've been mined. Yes, the inital mining and re-processing are a serious impact on the environment, as is the disposal of those parts that can't be re-processed into new batteries, or something else useful.
Wait, sounds a lot like nuclear, doesn't it? I'm not anti-nuke, I accept that its benefits come with drawbacks, too.
Put yourself in the mind of someone in 1966. Imagine the infrastructure, the cost, the ecological impact, the production of chemicals, and the waste of the {xxx} as they need to be replaced every 2 to 5 years.
{xxx} being high-powered computers in the home, smartphones, large-screen TVs, etc.
I've been off-grid with PV and lead-acid batteries for 2 decades now. Yes, the batteries need replacing every 8-10 years, but they're taken away for recycling, so I don't have a problem with that. In the meantime, I have no electricity bills (but a moderate bill for backup generator fuel), negligible downtime (for periodic maintenance and battery replacement), no blackouts during bad weather, etc. It's not suitable for everyone, but the "uneconomic", or "impractical" arguments don't hold up.
I see it this way - do you want centralised power generation, or should we try a distributed model? Either way, it's going to cost $$$. Let's examine the advantages and disadvantages of each, and make decisions based our interests, rather than the interests of those who want to sell something to us.
It's out there, lots of people use it and find it useful, it has its drawbacks, but it's not going away.
And lots of people hate it, detest it, loathe it, and degrade it, without really understanding it. Of course, they're perfectly free to continue loathing it, but they do themselves a disservice by not attempting to understand it better.
I've only ever owned twins with screw-and-locknut, so it's not really an issue for me.
The shim-and-bucket adjustment on a Honda CBX on the other hand, would be a nightmare. 24 valves, no thanks.
On the gripping hand, I was advocating the development of the technology. If the conventional cam/follower/valve stem arrangement can be made to require little or no adjustment, then surely a desmo system could also be developed further to reduce or eliminate adjustment.
Hope this doesn't count as a Godwin, but the germans were using fuel injection in their WWII fighters, and it proved a significant advantage over carburetted allied fighters - the FW-190 could perform a radical nose-dive which would leave a Spitfire fuel-starved.
Fuel injection has been around a LONG time - just like disc brakes - but they both took a long time to make it to mass-production motor cars.
The trailing profile on a cam is there to slow down the valve as it closes, to prevent it slamming too hard on the valve seat - if that wasn't needed then cams could be asymmetrical and look more like a comma than an egg.
There's usually a tiny bit of residual magnetic field there. Anyway, if your main battery is absolutely dead, you can excite an alternator with a lantern battery, then push-start the car.
Most motorcycle engines actually don't need a battery since they use a magneto connected to the crank shaft to fire the plugs.
Not since the early 1970s. Small stationary engines (petrol generators, water pumps, etc) still use this method, but not "most motorcycle engines".
Actually, most roadbikes and larger off-road bikes these days are fuel-injected - they're subject to the same or similar emissions rules as modern cars, and also use ECUs, so "no battery = no go", even though it's feasible to push-start them. Smaller off-road bikes still use carburettors and points+coil ignition.
A valve can only occupy the piston's space when the piston isn't there. i.e. there are physical limits as to how long the valve can be open, and having it open at a shallower depth, even for a longer period, is bad for efficiency. The airflow into the combustion chamber is driven by the lower pressure inside when the piston is on the downstroke, and you want your valve wide open as possible for a very brief window, not partly-open for a longer period. It's no good opening it at all until the exhaust has gone, and you don't want it open even a little bit once compression starts.
That's why multi-valve designs were invented. Two smaller valves providing a larger cross-section for air+fuel to flow work better than a single large one. Yamaha even had a 5-valve design - 3 inlet, 2 exhaust.
Solenoids could provide programmable operation for different requirements - e.g. touring vs. sports mode.

You're funny.
Shouldn't you be paying attention to the buggy-whip production line?

Yep - KB3035583 turned up again last week. It's whack-a-mole - inspect the list of patches, hide it, relax until next month when it turns up again.

This may have been covered already, but won't Apple have a record of the hardware ID, and be compelled by warrant to hand it over?

Uptime and I/O is why you buy IBM. Ask banks and insurance companies.
Also ask my previous employer. We had an AS400 that didn't need service until a disk controller failed when it was about 8 years old.
