No they don't. You just think they do. A lot of people do, it's what often leads to botched repairs. There was a good video on youtube showing what happens when an iPhone was assembled with a screw that was 0.1mm out of spec.
I don't think anyone was under the delusion that the metadata from the internet was anything they owned.... Or even cared to own.... Or would even work if they owned it themselves.

Unworkable. Right now you're talking about a completely secondary feature to the primary function of unpopular software which is well outdated and for which a company offered a free update path. Any legislation you pass that offers protection against such an edge case would have dramatic consequences.
You'll also get no support for this, not while Windows 7 happily boots and those files still play.
Seriously, who watches media with Windows Media Player when free players like MPC offer a much superior experience?
You know that the vast majority of computer users couldn't give a crap about the "experience" right? The vast majority will happily use WMP until they find something they can't play. Then they'll use that alternative software until they find something it can't do.
Interesting question. This is Slashdot where you are asking so are you aware of the concept of "observer bias"? The answer you will get here: no one.
The real answer: The 100s of millions of people who just use their computer and don't actually mess with any settings at all. I.e. all those Internet Explorer users from the past.
it seems wrong to regard the dwindling frequenters of/r/googleglass as Glassholes.
Based on what I see here on Slashdot the term Glasshole was used to describe generic use of google glass. A generalised statement along with a counter-intellectual assumption.
I originally thought it was something that Slashholes here came up with but apparently making broad negative generalisations about people is something that is done elsewhere too.
I'm often surprised at how camera shy people are, considering that they are being photographed and under video surveillance nearly constantly when in public.
Intent! People being photographed by a security camera to end up in some generic filing cabinet by some generic government or company unlikely to ever actually review said footage is quite different from a specific person pointing a specific camera into your face.
None of the 100+ registers had anything to do with networking.
The HiSilicon chips being discussed here are full SoCs that interface with the sensor. They among other things have everything to do with the networking.
Please post the link to your completely unprotected feed from your in-house IP camera. If you don't want to then maybe re-assess why this restriction is in place.
You should count the number of chips in a camera. If you get at the number 1 then you'd realise what TFA is actually talking about here and why it's a big deal.
The interface is just not suitable for any kind of attack against the main system
The HiSilicon parts are the complete SoC which handles *EVERYTHING*. It's suitable for every kind of attack you can think on for an IoT device.
Mozilla has a history of innovation. Regularly better than the others.
America has a history of civil wars so clearly they're going to go to war again right? The problem with looking at history is that it ignores changes. I loved the Mozilla of old..... It's gone now. They are working on releasing Clonium v65 shortly though.
And by saying "Missing something" I meant from the argument itself. It's useless arguing advanced chemistry with someone who doesn't even understand that the very base of their argument is wrong.
I didn't mean that you didn't address it, which you did. I wish slashdot had a Preview button:-)
Fortunately, chemistry doesn't work like that or smokers would die of explosions instead of lung cancer.
You're missing something far more fundamental. The MMR vaccine hasn't contained mercury for 2 decades (in any form since as you quipped ethylmercury and elemental mercury are not the same thing).
And yet I know many formerly employed, retired and career changed doctors and nurses who continue to take them every year. Mind you so do I, so does my wife, so does everyone with half a brain and access to a free medical system.
But when they do, they don't tell you so, and instead they continue marketing the vaccine as if it would be useful.
False. Targeting the wrong strain is something that you only find out after the fact. The information is openly published, and people who are extremely late in the season are advised to get the shot anyway simply because it still immunises you against the non-predominant strain of the season.
Don't go looking for conspiracies where there are none.
but it is outright fraud when they sell you vaccinations targeting the wrong strains under the claims that flu vaccinations save lives. Sure they do, but not those ones!
That is a dumb comment. It's like calling fraud the fact that you're dying of lung cancer after getting your HPV vaccine. You have still been vaccinated against a strain of flu, that flu still had the potential to impact you significantly. The fact that you get a different viral infection is a strawman so big it borders on a mental disorder.
But they advertise them exactly the same as the ones that will.
These companies have open positions for prophets who can predict the future. Do you wish to apply for the role?
Freedom of speech does not mean freedom of consequence. If I go on TV and make a comment about a legal proceeding involving my employer I can rightfully expect to be lining up at the unemployment office the very next business day.
The ambassador does not have a PR role and his only comment about this case to anyone outside of the respective governments involved should have been "no comment".
In nuclear's case the problem is that even relatively small scale accidents like Fukushima cause hundreds of billions of dollars of losses.
And yet that predominantly a problem of design not operation. Like seriously who builds a nuclear reactor on a fault line next to a tsunami prone ocean and then puts some 500000 people in houses next to it.
Solution: You build your geothermal plants in these locations
I don't think you really understand just *how* location specific these things are. Also while right about moving coal by train our goal should not be to replace one inefficient stupidity with another.
Now in the case of these chargers, you would also want energy going into the batteries.
Oooooh you're talking about wanting to not make heat and instead put more energy into the cables. Man are you good at this. First you suggest that the simple solution is to do the one thing they couldn't do (bigger cables), then you go and harp on about some completely insignificant inefficiency in a 350kW charging system like it's some kind of problem.
A liquid cooling system would be indicated if you were using cables too small for the purpose.
Nope, A liquid cooling system would indicate that the cables designed for the purpose needed cooling given other engineering restrictions.
Some further research shows https://insideevs.com/vw-elect... [insideevs.com] Yup, those cables are way too small to be passing 350 KW through them.
That isn't research. It's a statement from one manufacturer that their cables have a problem. It is a straw-man and not a good one. What next, Infinity cable recalling it's 2.5mm TPS is indicative that we shouldn't be using 2.5mm copper TPS to wire our houses? Shit man, someone had a problem! Change everything before we all die!
Yup, those cables are way too small to be passing 350 KW through them.
Actually they have been passing 350kW through them just fine.
You run coolant through the cables to cool them and keep them from vaporizing.
No you run coolant through the cables to cool them and keep the insulation from getting soft and degrading.
The coolant makes it possible to use that small of a cable, the cost is a lot of the energy being dissapated as heat.
Nope. The cost is a bit of energy being dissipated as heat.
And if the coolant fails? so will the cable - probably very quickly.
If the coolant fails the system shuts down. What is this amateur hour here on Slashdot? Even the non liquid cooled charging systems have safety systems built into them.
Could be a thousand amperes flowing through those cables.
1000A would be a problem given the cables are rated for 700A and the chargers just a tad north of 500A.
That is a dangerous design. Marketing tried to over-rule physics with the usual results.
It's a perfectly normal design required thanks to those pesky laws of physics.
This isn't rocket Surgery - so what do I not understand?
I don't understand rocket surgery. This however, I'm all over it. You on the other hand seem to have no idea why liquid cooling was chosen in the first place. Maybe go read up on it so we can start talking about this on the same level.
You're a genius. I'm not sure how the army of engineers working on bigger chargers managed to get so far without your help.
And I certainly wouldn't design a charger like that.
Clearly you wouldn't design any charger. I mean if you did you'd probably have read up about it and would know that the limiting factor for >150kW chargers as they stood was cable size and voltage rating for continuous flexible connect / disconnect systems.
But hey I can't help it you're so smart. You should go call up Porsche as soon as possible and tell them that after a year of engineering you had a much "better" idea. I'm sure they'll give you a wheelbarrow full of money./sarcasm
Oh, AC. I love it when people call me out when they are 100 percent wrong.
Hmm. Claiming I'm wrong while not even realising who you're talking to, you're not off to a good start.
There is a reason why we don't use 20 gauge wire in our car's starting circuit. Run a hundred amps through 5 feet of that and you have a fireworks show.
Indeed. Now if you cool that cable to -150C it will work just fine. Unfortunately for your straw-man argument we're not using 20gauge wire here, and it's not practical or cost effective to liquid cool cables in the car which is why they take a simpler engineering solution to this problem: A bigger cable, something which is not practical for 350kW chargers.
Oh lordy - this excess heat - Where is it coming from? The cable. Where is it going? Into the cooling medium. Where do we want it to go? Into the battery.
Yes, Yes, WTF No! Don't be silly. Making a conductor heat to >90C is not some horrible waste on efficiency in a 350kW charging circuit. Your battery won't miss the small amount of energy converted into heat.
And if that cooling system fails, we likely have a bad situation very quickly.
Nope. We're likely to have an ok situation which escalates quite slowly to a bad situation, water has quite a high specific heat and the failure of that cooling system is easy to detect at which point the charging system gracefully shuts down and gives an error.
I'm reading very roughly 1000 amperes, which is nothing to sneeze at. And looking at the cables on that recharge station, I'm guessing less than a second to shut it down.
You're reading wrong and extrapolating incorrectly at many fundamental levels.
1. On top of water having a high specific heat you know what else does? Copper. You're also ignoring the fact that these cables are quite substantial as they are. Not to mention that loss of flow detection can be pretty much instant, though in practice there is usually a 1-2s filtering to prevent spurious dropouts. Even if your assumption was correct it still is an easy engineering problem.
2. 1000A while nothing to sneeze at is also nothing that is magically hard to handle with some high school engineering. A 4/0 gauge cable can handle this current continuously without any extra cooling with standard PVC insulation. Dropping the wire just a few gauges and adding a failing liquid cooling system will result in a graceful but time generous temperature rise.
3. Your guess is off by a factor of 100%. The 350kW chargers transfer no where near 1000A. The cables in question (and more importantly the connectors at the end) are rated to an absolute max of 700A and that includes a 20% safety factor.
This. If the cable is getting hot, the conductor isn't big enough for the current its carrying.
This is a dumb comment. Every cable heats up regardless of size if the current is non zero. Whether that temperature rise is too small to measure or not is irrelevant. Cables can happily run hot enough to be glowing red and still happily pass current, the question is if that cable is safe to handle.
Liquid cooling is just a way of increasing the current carrying capacity which is limited by the temperature rating of the non conductor components in a cable, specifically the insulation.
