Straight from the website: "When the device is charged, -200VDC is discharged over the data lines of the host device. This charge/discharge cycle is repeated many times per second, until the USB Killer is removed." So not thousands. And it does have A LOT of amperage behind it. That's why it works. It can surge a large amount of amperage for a very brief time, which can cook any hotspot in a silicon device once it's broken down (which it will do because nobody is putting 200V process silicon parts in high speed USB devices).
USB protection is designed to prevent against reasonable faults (a device drawing too much power, minor overvoltages, ESD strikes). This is not a reasonable fault. Additionally, it surges the data lines, which are more sensitive. They have to be more sensitive because they are high speed lines that have signal integrity constraints. You can't just start adding protection to them willy nilly without affecting that.
Their cover story is "The USB Killer is a CE Approved and FCC Approved testing device designed to test the surge protection circuitry of electronics to their limits - and beyond." which we all know is B.S. And It's probably not likely people will start designing their USB hardware to survive this unless people don't quit acting like dicks.
Yeah, they want to see growth constantly, because it's the only way a system can work that's based on huge amounts of debt. With the fallacy that if you grow fast enough, you can stop from sinking deeper in the hole.
Somehow nobody really seemed to stop to take a look at natural systems, where everything must eventually find an equilibrium or suffer certain collapse.
You don't let them inspect and self-authenticate their designs as safe
I see a lot of people harping on this. Irrespective of how true the other points may be, the truth is this happens in all sorts of industries, even where safety is involved. Even UL allows it, if you are a big enough company. You are essentially just submitting your results and analysis to them. They give it the okay, and there you go, UL approved.
We can argue if it's the right way to do things, but acting like it's a unique instance doesn't align with reality.
They already did once. Now they are appealing. And I'm sure this one case is not about the money, it's about the precedent it sets. Because they want to be able to point to a case and say "Look, we can hold you liable for not doing what we say!". But as it stands right now, it's quite the opposite.
Well, manufacturing goes like this: Pay through the nose per unit if you want it right now and custom. Or pay a bunch upfront for tooling and wait much longer, then get them very cheap per unit in high quantity.
Also, you're assuming the shop allowed Apple to occupy their entire workload for these screws, which is unlikely. In fact, it's more likely Apple wasn't getting much volume simply BECAUSE the shop wouldn't dedicate much time to it, probably because it wasn't worth the money.
Austin is not the place for high quantity fabrication. Yes, there are some machine shops in town, but most of Austin is very similar to the South, in that there is much less manufacturing. Houston has more, but mostly to support oil operations.
Every day here more industrial and garage type spaces get turned into crossfit gyms and breweries. (not that I'm particularly against either, just a point blank example of what is thriving here).
Side story. Years ago I spotted an awesome vintage garage for sale/rent. I thought it might have been my chance to have a shop of my own. I talked with the owner. He essentially told me "You don't want to do that". The combination of high taxes and environmental restrictions were essentially why he shut it down in the first place. He flat out told me he was hoping for a trendy tenant. Bar/restaraunt/what have you.
Agreed. I have no medical background, but I can't help but feeling that bacteria from gum disease seems way too easy for a disease that has otherwise been seemingly very complex to analyze.
That is some finely worded angst. And well deserved too. Love the people trying to invalidate you by poking at your username and using "whatabouts". But it's all pretty true. It's become a bloated cash cow.
To quote some good song lyrics:
A sacred cash cow with sickly tits
Dripping temptation for hypocrites
To death she's beaten
The prosperous endlessly stating the obvious
You jest.. that's exactly what my they are trying to get people to notice.. A catchy headline, a result backs it up. All to produce a study that is clearly crafted to get the reaction and attention desired, all while being essentially crap under the surface.
There we go. Finally. Is this what we've come to? Doing the worst because you think someone might do that same to you. No wonder this society is in the shitter.
"But, but, they'd do it to me!". Oh please, grow up. If you want to be treated professionally, then be professional. If you don't get treated professionally, move on when the time is right, be professional, and never look back. Positive change doesn't come from acting first and playing tit for tat. It comes from doing what you know is right even when you might not expect to see a return.
What benefit does just walking out possibly have? Yeah, you might feel cool for a day or two, but you've burnt a bridge. Do you think the company cries itself to sleep at night now wondering where you are? So what are you left with? Only negatives, no positives.
I remember letting the demo download all night long and overnight on dialup. Was out in the boonies and that was the best we had, but man was it cool when it finally downloaded.
Obviously a complaint from someone with no experience on the matter. I work for a large electronics company. We used to sell equipment with filters for tha fans. Guess what? They plug up faster and cause the equipment to fail sooner than if it was there or not.
Doesn't matter that they were serviceable/replaceable. Doesn't matter we talked about it in the manual. That's just the way it is.
Not necessarily. The Fab is very important. It's the other half of the equation. You need the fab processes to create the devices necessary for your designs. However, Intel got to where they are not only because of their fab technology, but also their design technology. Creating design tools capable of handling nearly a billion transistors is no trivial matter. They did not exist. How do you standardized logic cells? How do you lay them out so they actually are capable of the speed (timing) you expect. How do you describe that. How do you test it? Design tools. And Intel was/is very good at it.
While I generally agree, if you have kids, it's not necessarily anyone else's duty to make special concessions for you (it IS a CHOICE after all). This I think, crosses the line pretty obviously. It is not that it just so happen that families got split up, which I would totally expect as the larger your party gets, the harder it is to get contiguous seating. However, the claim is that families were specifically targeted and split up to exploit their known desire to sit together. It's quite obviously a predatory practice.
I was curious about the energy density of this proposed solution. I dug in the comments and found a reply from the author of the study. Kinda interesting.
There is no “minimum storage pressure” but the economics are poor for anything lower than 50bar. For CAES with tanks, the economics push you towards pressures of 200 - 250 bar. In caverns, the pressure you can use depends on the cavern depth. 120bar is not unusual. For a cavern with 120bar storage pressure that was allowed to swing down to (say) 70bar when “discharged”, you would be storing ~23MJ in each cubic meter of cavern. Thus for 1GWh (3.6 million MJ), you would need 156,000 cubic metres of cavern. That is actually a relatively small salt cavern! If it was a sphere, it would have radius of 33.4m. Surprising as it may seem, most salt caverns in existence are bigger than that!
I worked a full day time job behind a desk as an engineer. By night I was a fabricator/welder at a race shop. I enjoy engineering, but I wasn't satisfied with what I was doing and losing my mind not making things with my hands anymore. Since I grew up around racing it was a natural fit.
Before my wife had a serious talk with me, I was doing at least 12 hours and growing on weekdays, a full day Saturday, and helping at races on Sundays some weekends. Truth be told, I was eating it up. I don't do well sitting around. But in the balance of priorities it had to go.
I've since switched to metal working (machining, welding, scraping, etc) in my garage at home. Lets me get out some of the desires, but a more sane pace...
I'm right there with you. My wife and I are in our 30's and don't have even a twinge of wanting kids. And for the trolls: I don't go around getting in people's faces trying to rain on their parade if they already have kids. (However, if they cop a "your life isn't complete without kids" attitude it's all fair game)
IMHO opinion, the easiest and most humane way to help the environment is TO STOP MAKING MORE PEOPLE. Economies will have to learn how to deal with not having a generation of more abundant people to clean up your mess after you (aka living in constant debt), but the environment doesn't give a flying flip about economics.
But it's not gonna happen. So whatever. I just consider myself lucky to have been able to have experience how beautiful the planet can be. It breaks my heart to think about creating somehow who might lose that.

The dirty secret: Most of the time the dog alerts due to subtle cues from it's handler, not from something it smells.
That's certainly an interesting assertion. Is it anecdotal or have people/studies shown this?
They already did once. Now they are appealing. And I'm sure this one case is not about the money, it's about the precedent it sets. Because they want to be able to point to a case and say "Look, we can hold you liable for not doing what we say!". But as it stands right now, it's quite the opposite.

In debt or behind/default on debt? I'd say that matters a lot.
In any case I still think it's a disgusting idea.

This is the most poignant assessment of current culture I've seen in a long time. Bravo to you.
We wish. More like pandering to a constituency to keep their favor.
First it was trial by jury, then it was trial by media, now it's trial by social network and media.

Is it real time, interleaved, or synchronous sub sampling (aka aliasing aka stroboscopic effect)?
