What MagSafe on the iPhone 12 is, how it works, and what can it do
randominternetperson said:I'm not a hater by any means, but what happens when you put an iPhone 12 in the same pocket as a hotel keycard? I've had these get messed up from time to time when I wasn't carrying a strong magnet around with me.
Maybe it won't matter since hotels barely exist post-Covid. Or it will force them to support using iPhones to open hotel doors (as a very few hotels do already).
Actually, screw hotel key cards, what about the credit cards in my (mini) wallet? I routinely have credit cards in a leather sleeve in the same pocket as my phone. Will I have to replace that with a shielded sleeve?
Most magswipe cards meant to be used for more than a week (such as most credit cards) use high-coercivity magnetic strips, which are considered permanent magnets. They can still be rewritten, but it takes a much stronger magnetic field. Little short of direct contact with a neodymium magnet should be able to affect them.
The shielding they talk about is just a high-permeability metal (like iron or certain steels) inside the leather. The idea is to give the magnetic field a shorter path between the poles which doesn't go through the card strips. I bet there will be cases which have shielding to protect cards, but which break the ability to use a MagSafe charger. -
Apple launches iPhone 12 Pro line with new design, better cameras, LiDAR
The zooms listed above are slightly wrong. For the Pro, it's 2x in, 2x out with the wide lens as the point of reference. The 4x is the full optical zoom range from widest to narrowest. 10x optical zoom is based on the wide lens as 1x. The Pro Max is 2.5x in, 2x out, 12x digital zoom (I suspect it's actually 12.5x; the digital zoom is 5x the long optical lens).
The full zoom range for the Pro is 4x optical, 20x digital, with the ultrawide lens as the point of reference.
The full zoom range for the Pro Max is 5x optical, 24x (or maybe 25x) digital with the ultrawide lens as the point of reference.
And it looks like only the Pro Max has sensor-shift image stabilization, and only on its wide lens (not ultrawide or long). -
Apple releases iOS 14 and iPadOS 14 updates

What magic let's the update mechanism know or care where in the UK a person is from?
Certain DNS servers have the ability to pick between a bunch of records to hand clients based on things about the client or about the servers. For example, this technique is sometimes used to send clients to less-loaded servers. In this case, it's used with a geolocation guess about the client to send clients to a CDN server which is physically close to the client (really most CDNs care more about BGP hops, but that's like geolocation).
This problem appears when not all of the servers in the CDN have the same files, and the DNS redirection sends some people to one which does, and others to one which doesn't yet.
** Nope didn't work. Oh well, was worth a shot. -

ARM deal nears closure with Nvidia mulling $40B purchase from SoftBank
cloudguy said:tmay said:cloudguy said:tmay said:I don't imagine that Apple has concerns one way or the other. Apple is likely at a point where they have in house capability and have licensed necessary IP to create their own proprietary ISA, while also large enough to create the design and validation tools needed to fab at TMSC, or whomever.
I would prefer that ARM reside in Japan or the UK, and not Taiwan, simply for National Security reasons.
Another thing: basic R&D like this isn't Apple's deal. It is amazing that so many people are convinced that it is. In fact, Apple doesn't do originality. Instead they take existing technology - stuff that has been around for awhile and has been proven - and incorporate them into their existing design language. At most, one could say that they excel at taking parts innovated or improved by others and using them to make new great products. But the truth is that nothing in Apple's present existence or their previous history indicates that they are capable of coming up with a "new" CPU design, or even a major advance on an existing design. Even their own CPUs, in addition to being based on the existing ARM design, were the result of acqui-hiring PA Semiconductor. Even something MUCH SIMPLER such as a fingerprint scanner, they had to buy a company that already had the tech, where Qualcomm and Samsung created their own using their own R&D departments (which is why they were able to make under-the-screen fingerprint scanners so quickly).

Apple has never been challenged in SOC's since.
"Apple doesn't do originality" is a bullshit meme.
1. That is still an iteration of the original ARM Holdings design. It is just a better one than Qualcomm and Samsung's.
2. It is ALSO the result of Apple BUYING the PA Semiconductor company. Not Apple's own unique design. So your rejoinder only confirmed my original comment. I repeat ... there is NOTHING that indicates Apple having the ability to create its own original ARM CPU design, especially a design that maintains the power and performance advantages that the ARM Holdings and PA Semiconductor designs have.
P.A. Semi was founded in 2003 and Apple acquired them in 2008. That processor, the A7, debuted in 2013. They existed for five years separately, then five years within Apple by the time the A7 launched. Furthermore, their work when independent was on a POWER ISA core, not ARM. It's fair to call the A7 an Apple-originated design.
As for Nvidia potentially acquiring ARM Holdings, I suspect their interest is mostly in the high-performance computing world. Right now, Nvidia GPUs are peripherals of Intel or IBM processors. They're the main compute in six of the top ten supercomputers in the world as of June. Nvidia wants an Apple-like degree of control over their own fate (a big reason Apple doesn't use Nvidia cards anymore is Apple doesn't want other companies writing kernel-space code, and Nvidia doesn't want another company writing their low-level drivers). Earlier this year, they purchased Mellanox (which does InfiniBand and other high-performance interconnect chips), then a week later they also purchased Cumulus Networks (which does datacenter interconnect operating systems). Give a GPU a Mellanox transceiver instead of a PCIe transceiver, hook it up to a Mellanox switch managed by an ARM processor running Cumulus software, and Intel and IBM are no longer in the picture.
