Apple settles with student after authorized repair workers leaked her naked pics to her Facebook page


Re: Details

Apple is claiming in court that they shouldn't have to release repair information because consumers going to third parties for repair is a theoretical privacy risk.

This story is about Apple's "in house" (which is really contracted out) repair being a proven privacy failure.

Does that tie it together for you?

FYI: Today's computer chips are so advanced, they are more 'mercurial' than precise – and here's the proof


Re: Error detection

CPU redundancy has been around almost since the beginning of electronic computing, but it largely disappeared in the early 1990s as caching and asynchronous interrupts made cycle-by-cycle comparison infeasible.

My expectation is that this will turn out to be another in a long history of misunderstanding faults. It's seeing a specific design error and mistaking it for a general technology limit.

My first encounter of this was when dynamic RAM was suffering from high fault rates. I read many stories on how the limit of feature size had been reached. The older generation had been reliable, so the speculation was that the new smaller memory capacitors had crossed the threshold where every cosmic ray would flip bits. I completely believed those stories. Then the next round of stories reported that the actual problem was the somewhat radioactive ceramic used for the chip packaging. Using to a different source for ceramic avoided the problem, and it was a motivation to simply change to less expensive plastic packages.

The same thing happened repeatedly over the years in supercomputing/HPC. Researchers thought that they spotted disturbing trends in the largest installed systems. What they found was always a specific solvable problem, not a general reliability limit to scaling.

Supermicro spy chips, the sequel: It really, really happened, and with bad BIOS and more, insists Bloomberg


Re: The impossible bus

It only takes a few pins for a serial flash, and that's the type of flash used on a management processor.

But there is no evidence that the modification ever took place!

I could have come up with a much more credible story than the Bloomberg story e.g. using direct editing of Gerbers to support a COB/DCA modification under an existing component.

But, again, there is no evidence that any modification ever took place!

File format conversion crisis delayed attempt to challenge US presidential election result


Re-read the actual details of the message the Japanese ambassador was to deliver.

It wasn't a declaration of war. It was a passive statement about a unilateral cessation of negotiations. Which, it might be argued, implied that something else might happen ('war is a continuation of negotiations by other means'). But it wasn't an explicit, direct, immediate statement.

This ambiguity was the reason why both the interception and the ambassador's scheduled meeting were not considered top priorities. It was only in retrospect that they were accorded significance.

Watt's next for batteries? It'll be more of the same, not longer life, because physics and chemistry are hard


Re: On the subject of EV recharging

The idea of replaceable battery packs has been floated. Many, many times.

Tesla even had an on-stage demo.

But everyone concludes that the logistics don't work out. Even if you can get everything else right, such as standard form factors to support a variety of vehicle types and how to do automated quick swaps over a range of vehicle types, you still can't create a cost-competitive system.

First, you need to produce and pay for multiples of the most expensive part of an EV. That multiplier isn't going to be close to 1.0. Depending on your assumptions, it might be above 2.0. If your system relies on transportation to a central depot for charging, and buffer stock at heavily used stations, it could be higher. If you need to support a regional crisis, such as hurricane evacuations, it could be significantly higher than 2x.

Next you need to deal with how to pay for pack degradation, including aging, use and physical damage. If you are proposing battery-as-a-service, you are likely proposing a national utility-like monopoly. If you don't want a monopoly, you need to come up with a valuation formula that isn't trivially gamed. And keep changing the rules as new ways to cheat are found. And try to stabilize prices in an economic system where the rules constantly change. The mind reels at how complex the rules would need to be, and how expensive the system would ultimately become.

Atlantic City auctions off chance to hit Big Red Button and make grotesque Trump Plaza casino go boom


Re: "Made a lot of money and got out"

A subset of owners almost certainly did make money overall. And the parties with "losses" likely did pretty well.

If it is your goal, it's easy to make lots of revenue go out the side door, rather than show up as profit. Then the primary corporation folds with a giant paper loss, generating tax benefits for the shareholders and bad loan write-off tax benefits for the lenders.

Trump accumulated tax-credit 'losses' wildly in excess of his investments through the 1980s and 1990s. Those losses were part of his tax avoidance through at least 2014.


Re: And put the button

According the Washington Post story, the limit is no more than 7 days consecutively and no more than 21 days a year. It applies to any guest, not Trump specifically, but Trump's attorney at the planning meeting did specifically agree that Trump would adhere to the restrictions.

Curiously, it throws Trump's Florida mail-in vote into question. He arguably voted illegally, since his proper domicile should be either New York or Washington D.C. For 2017 and 2018 he spent a total of 69 days in Florida, which was not enough to establish new residency when it still had a stronger presence in New York.

Re: Trumpian Moneybags

I haven't seen a suggestion that Trump was invested in HP.

£2.5bn sueball claims Google slurps kids' YouTube browsing habits then sells them on


I'm not sure if I consider this lawsuit reasonable.

But saying that YouTube isn't for kids under 13... that's obviously BS. There is plenty of content targeted to very young kids, and teachers that are requiring kids to watch YT videos for class. (That is a problem at home because we now need to enable YT access during the school day, which leads to a string of distractions.)

Take your pick: 'Hack-proof' blockchain-powered padlock defeated by Bluetooth replay attack or 1kg lump hammer


I'm curious at the characterization of Zamak alloys as "hard wearing".

I think of it as "easily melted". It is able to be cast with fine surface detail and minimal shrinkage, allowing die cast parts to be used without any machining. But beyond that, it doesn't have great properties. It's not strong against impact. It might bend before breaking, but really only enough to make the cracked-off piece difficult to repair. And if it's doesn't break, it's has work hardened so it's going to break when you try to bend it back. It can be plated, but there is a good chance the surface will degrade even with no exposure to moisture or chemicals.


Re: Confessions of a bolt cutter

Lock picking isn't difficult.

But it's less predictable than bolt cutters. Bolt cutters usually work, and work quickly. If the bolt cutters aren't going to work, you'll get that answer in a few seconds.

It's usually worth spending more money defeating bolt cutters than lock picking. Someone with bolt cutters is definitely up to no good and will cost you money. Someone that picks the lock hasn't yet demonstrated that they want to steal or destroy.

Physical locks are less hackable than digital locks, right? Maybe not: Boffins break in with a microphone


Re: WD40?

Know how the lock is lubricated before applying anything.

Automotive locks are typically lubricated with clear waterproof grease. Applying graphite will gum them up horribly. Lock de-icer works great to rinse out dirt and redistribute the grease, although you'll need to re-grease after a handful of uses.

Residential locks are typically brass with hardened pins. They are lubricated with a few percent of lead in the brass, not an external fluid. Graphite powder will help temporarily but lead to long-term clogging.

Back to the article: most locks above entry level have features on the driver and key pins that will defeat this approach. These features are a trivial additional cost.

Re: No file exists...

I was bitten, hard, by a similar file system problem.

The standard Unix file system (BSD FFS, Berkeley Fast File System) put all of its effort into metadata consistency, and none in to file data consistency. When sometimes had the effect of "correcting" corrupted directory entries to point to zeroed blocks if they were invalid. While in some cases it wasn't entirely silent about doing this, it wasn't a fatal file system check error. The messages looked the same as and were buried among the many others in the boot log after an unexpected shutdown.

The result was that the data directory looked entirely correct, with no indication of a problem. File permissions, timestamps and sizes were correct. But some the file contents were zeros. Which were dutifully backed up, overwriting the incremental and then staggered backups. A few weeks later when this was discovered, there was no backup, on-site or off-site, that contained the data.

Ironically, this was in the middle of BSD Unix fans slagging the Linux file system designers on how "unreliable" it was by not implementing continuous metadata consistency. A Linux crash would often result many more metadata inconsistency problems, but almost never file data corruption. And especially not the horrendous silent data corruption when the directory structure appeared consistent (because the file system programmers cared about "their" directory structure and performance benchmarks, but not the user's data).

The point here is that you can have a sophisticated, responsible backup scheme and still lose data. Saying that "the harm wasn't our fault because they should have had backups" misses the point.

What legacy is IBM really shooting for? Cheating its own salespeople out of millions? Here we go again, allegedly


Re: Fuck IBM

That doesn't trump a paper contract. Which they had.

IBM claimed that was only a contract when it came to satisfying employment laws, not when it came to being paid. That they got a lawyer to make that argument, albeit in disconnected cases, shows that IBM cares cares more about per-quarter financials than long term business and reputation.

Splunk sales ace wins sex discrimination case after new boss handed her key accounts to blokes deemed 'flight risks'


> Splunk spokesman Alex Harking claimed in a one-line statement to The Register that the company "does not tolerate discrimination in any form", adding: "We are committed to fostering an inclusive environment."

I'm a fan of Splunk, but the next time you see a statement from them remember that they are empty words.

You can say "we disagree with the tribunal and will be appealing", or "we are disappointed in the ruling" or "we are reviewing the decision to plan a constructive path forward".

Saying 'none of our internal rules or policies were broken' after a ruling that they broke the law suggests that they are fostering an inclusive environment for sociopaths.

IBM quits facial recognition because Black Lives Matter


I don't agree about the U.S. not entering the war, but do agree with your main point: many large U.S. corporations engaged in world trade, and world trade meant selling to Axis countries. Many in the U.S. praised the German economic recovery from afar, with most of those not understanding the "ground truth" of what was happening.

Most here know of the IBM sales that helped Nazi Germany track undesirables, which was largely a commercial rather than ideological relationship. Few talk about Ford's outright praise and admiration for the Nazi leaders. (I realize there is a little bit of "what about.." there. My point isn't that IBM should get a pass, but that they weren't atypical. They were willing suppliers rather than active supporters.)

Re: Never understood this

"Certainly you are in the USA, such a dryer is a kilowatt-devouring monster. And "modern" (i. e. about 20 years old) humidity control versus time control yields superb results in terms of drying speed and nearly-ironed clothes."

I've lived in many places where a gas or electric clothes dryer was the only reasonable option. Your situation does not represent the universal experience.

You are a few decades off for the advent of humidity/dryness sensors. They save power, but not quite as much as most people imagine. The simpler mechanism of increasing the timer speed when the outlet air reaches the target temperature is approximately as effective and less prone to false shut-off.

Re: The rule more than the exception

ICANN finally halts $1.1bn sale of .org registry, says it's 'the right thing to do' after months of controversy


Re: DAMN, we were THAT close!

I agree: if they sue, they open themselves to discovery.

No doubt they are considering it right now, with the board members in their pocket agreeing to a quiet private settlement. But that runs of the risk of a change in board control undoing the plan and discovery happening. Or the CA attorney general coming around for another look.

It's better for them to lay low and try again later. Perhaps fewer people will be watching. Perhaps everyone will have gotten used to the idea.

Keen to go _ExtInt? LLVM Clang compiler adds support for custom width integers


This is quite an old concept.

Almost 30 years ago I worked on a compiler for dbC (https://ieeexplore.ieee.org/document/279474). A key feature of this language variation was arbitrary length variables. The initial motivation was SIMD, then quickly FPGAs.

Since the hardware structure has no inherent word size, a language that allowed exactly the desired precision resulted in code that was smaller and faster. And for a certain class of problem that used modulus, it resulted in significantly clearly code.

The problem was that for all other types of problems, allowing arbitrary precision was a huge distraction. Programmers micro-optimized the range, and then were bitten by bugs or unexpected behavior. A 32 bit variable is a huge waste when you are typically iterating to 100, and still a huge waste when you change that to 500, but you don't have to worry about a u_int8 (or the equivalent of a u_int7) biting you in the ass when the change is made.

- The marketing department couldn't convince someone from the technical side to participate, and didn't have the political pull to force someone to do it. That would be some combination of inept internal marketing, internal power wars, and active indifference by the technical team. Some combinations would leave marketing blameless.

- Some marketing hack wanted "control" of the conversation and didn't trust the technical people to properly lie about plans, schedules, features and bugs.

- Some marketing hack thought that they would actually answer the questions. Which is absurd. Dunning-Kruger absurd.

They aren't going to be asking a question that could be answered by skimming a manual or using the application for a few minutes.

Another part of the problem was spending wildly on making WeWork a lifestyle/workstyle brand, when that wasn't where the market is.

French pensioner ejected from fighter jet after accidentally grabbing bang seat* handle


Re: Double ejection

Thanks for adding the details.

Presumably the straps were tensioned for the ejection, which would change them from tight to extremely tight. And the pilot would have felt the explosion under his seat. Once he figured out that a single ejection happened, he must have realized that he no longer had the option of ejecting himself.

As for blaming the pilot for any part of the badly-done prep, I don't see that. Presumably the pilot was already strapped into place and had no ability to check the passenger. He was relying on the ground crew for that.

Not a Genius move after all: Apple must cough up $$$ in back pay for store staff forced to wait for bag searches


I expect that this ruling will be narrowly applied.

The unique circumstances were that employees were required to wear uniforms at work, and prohibited from wearing them away from work. Thus carrying bags to work was a normal part of the employment.

Few companies will have exactly the same rules. Those that do will change them minimally e.g. specify that employees may change out of their uniforms at home, but must cover them up when not working in the store. (Where do you keep the coat to cover up with? That's not their problem, but the situation is different. Now get back in line and wait to be searched.)

> Actually the ford Mustang shipped to NZ has 2 star crash ratings because the murderous the c*nts at ford decided to save a few bucks (and because such cars can still allowed here after successful lobbying by car importers and shameful back down by the govt).

That didn't sound right, so I looked up the details.

You wrote it as if the "Ford Mustang shipped to NZ" was different from the car sold elsewhere. It isn't. They didn't omit any parts, or cheapen the structure.

The two star rating was in 2017 with a newly established rating system. The same car with a different branding (as a Falcon) got a four star rating when introduced under the 2013 version of the tests. Like almost every recently designed car, it probably would have gotten a 5 star rating with older tests.

The Mustang increased to a 3 star rating in 2018, so saying "has" is somewhere between misleading and wrong.

I'm not defending Ford here. Their older design seems to have not considered the safety of the (token?) rear seat. But your claim is neither correct nor supports your point.

We’ve had enough of your beach-blocking shenanigans, California tells stubborn Sun co-founder: Kiss our lawsuit


The usual comment is that this case is about "private property rights being trampled by the government".

But this is like an easement for sidewalks or power lines that the government enforces. In many places you own the land that the sidewalk is on. You paid for it and it is 'private' property. But you have no right to block it, you must allow the public to pass, and you must pay to repair it as needed. You might even be obligated to expeditiously clear it of snow and ice.

It's all part of the bargain of living in a society that has sidewalks.

Here he bought property that has the sole land access to a public beach, in a state where the public has affirmative access to those beaches. He knew that when he bought it. Yes, his property might be worth not quite as much because of it. But that easement was built into the purchase price, just as the cost and benefits of a sidewalk are part of the value of a regular non-$30M home.

My view is that he has effectively stolen a public beach for a decade. What is the value of that? I think it's pretty high, much higher than the $30M he paid for the property he legitimately bought. I believe that the fines should reflect that.

Re: My goose is cooked

A wall wart type power supply can well over 90% efficient, with a few at 96%. Older ones tend to be in the 70% range with substantial idle power.

On a abstract philosophical level I'm opposed to government intervention in the marketplace beyond basic regulations, but here is where reality runs into dogmatism. A big chunk of credit goes to Energy Star (and the similar requirements from other governments). Those regulations made a huge difference in the world. Few retail customers buy on the basis of power supply efficiency or idle power, or even think about it. But, thanks to those regulations, we are in a virtuous cycle of increasing power density and a need for increasingly efficient power supply designs to support that density.

My favorite easy-to-explain design improvement is that power supplies used to have a discharge resistor to quickly drain the high voltage from internal capacitors when the power was switched off. This resistor constantly wasted power, but only provided the safety benefit for a few seconds each time the device was powered off. Efficiency regulations motivated the development of a chip (really a chip feature) that only discharges the capacitor when the pulses of the AC line are missing for a few seconds. This chip costs much more than the simple resistor, but saves far more than that in electricity over its lifetime.

Bringing it back on topic, we put all of that effort into efficient power supplies but wireless charging is typically only 50-70% efficient. It's going to be overwhelmingly the largest waste of power in running small electronics.
