So let's explore this. The Pizza parlor invests in nine 1.5 meter square pieces of plywood painted with a high-contrast landing pattern, with suction cups and straps to tie them onto drivers cars. Let's call that $500. They invest in a dozen big drones capable of carrying, say, four extra-large meat lovers pizzas in an insulated pouch - Let's call that $25000, dwarfing the cost of the landing platforms.
Now, the Pizza parlor hires nine drivers for a Friday evening, straps platforms onto their cars, and sends each to a different area surrounding the parlor. An order comes in, the pizza comes out of the oven and gets popped into the heated box under a drone, the drone goes and finds the closest driver. The driver may be in front of the desired house at the moment, or may be at the previous house - the drone lands, driver moves pizzas to his front seat, and delivers them to the desired house and collects his tip. If the driver is in motion, he pulls into the nearest parking lot, waits for the drone to land, and collects the pizzas. From the Customer's point of view, nothing changes in the current pizza-delivery model except their pizza arrives in 15 minutes instead of 45, and is likely hotter when it gets there. From the Driver's point of view, they deliver more pizzas per hour with fewer miles driven. From the Pizza Parlor's perspective, they've made a huge capital investment, but they're delivering 2-3x the pizzas they used to. From everyone else's perspective, there's a constant stream of annoying drones flying overhead (and occasionally crashing into their neighborhood) destroying their ability to peacefully enjoy their backyards. I guess that's an externality that just doesn't need to be considered.
Perhaps the simplest answer is most likely: someone watched him enter his passcode and/or GMail password BEFORE they stole the phone. Or, as someone else suggested, the mean kid in school made him give it up.
Even digital signals are subject to SNR degradation - a crappy cable will increase the Bit Error Rate, eventually overwhelming the error correction capabilities of the protocol and introducing errors in the data. Remember that, once you put a digital signal on a wire, it's now an analog signal (google "telecommunication eye pattern").
>>> I doubt most people could tell the difference between variable 320 kbps (kilobits/s) and CD quality even with quality headphones for most music
Well, back in the day when we were encoding with pirated copies of the Fraunhofer codec, I actually tested this. I created an audio CD with 4 sets of DDD tracks - one classical, one Rolling Stones, one solo piano, one something else. Each set had five tracks - the first track was the uncompressed CD-rip, and following this (in a random order that only I knew) were another copy of the uncompressed CD-rip, 96 kbps, 128 kbps, and 256 kbps CBR MP3 encoded then decoded tracks. I handed out disks to a dozen of my engineering coworkers, and asked them to take them home, put them in the cd-player on their high-end stereos and come back and tell me what the order of the tracks were.
It was comical. Half of them didn't even guess, because they admitted that it would be a random guess. Almost everyone could identify the 96kbps track, but no one could tell the difference between 128, 256, and uncompressed. One guy hooked it up to his home oscilloscope and spectrum analyzer - he noted that he could easily identify that the tracks were different, but he couldn't identify which was which except for the uncompressed one - he could see on the waveforms that it was identical to the uncompressed first track.
Now, I fully believe that it's possible for some golden-eared listeners to be able to tell 128kbps from flac - and I believe that it's possible for some to train themselves to tell the difference (though I don't know why you'd want to torture yourself for the rest of your life by doing that). But my ears in my early 30's couldn't tell the difference, and my ears now can't tell the difference, so I'm really happy playing my music through whatever electronics I happen to have around, although I am willing to pay for good speakers because those I can tell a difference.
>>> Geese tend to fly away from the big noisy machine.
Goose nervous and sensor systems weren't designed to detect and avoid 200 MPH airplanes. That's kinda like saying "Dogs/Cats/Squirrels/Deer tend to run away from big noisy cars". Perhaps "tend" is the correct word, but it's a long way from "always".
...to transition from Lightning to USB-C. They had to have a way to maintain their revenue from selling $20 cables, and licensing the ability to sell authorized cables. I don't know how many lightning cables I've thrown away because they worked for three months, then Apple updated IOS and blocked them.
Now I'll have to buy Apple USB-C cable, and HP USB-C cables, and Lenovo USB-C cables, and Nikon USB cables, and Microsoft USB cables. And, with OEMs promiscuously relabeling each others products, I'll never know which cable to use with which devices.
They've re-invented the RS-232 connection nightmares, but without the ability to carry a bag of dongles that might straighten things out. And so dies USB as the most successful cabling and protocol standard in technology history.
I'm not opposed to nuclear power - especially modern nuclear power. I really don't understand our (the USA) resistance to fuel reprocessing, or funding a "permanent" disposal process and location.
But the industry really hasn't convinced me that building large nuclear baseload generation plants is the best path forward for the next 100 years. Distributed and utility-scale Solar seem to be on a remarkable cost curve, which if it continues suggests that daytime power needs can be easily covered - in which case one can ask what you're going to do with power from advanced nuclear during the day. It's unlikely to be viable to only generate power at night (and nuclear power plants aren't good at varying loads). Massive investments in advanced power storage technologies - pumped hydro, batteries, etc - combined with Solar and Wind (although I really hate the visual obscenity of hundreds of acres of windmills) would seem to be the far better approach.
"When companies do immediate layoffs with no severance it is usually because the are bankrupt and going out of business, and the "evil" managers are losing their jobs as well."
Infant failures are common in electronics ( https://www.weibull.com/hotwir... ) From a simple standpoint, imagine a poorly soldered junction on the PCB - soldered well enough to pass QC and work initially, but after a couple of heating cycles the solder joint fractures. The same kinds of problems occur inside chips - wire bonds between the package and die may be defective but initially conductive, and fracture due to thermal cycling. Similar problems can occur on the die. The gate oxide for a particular transistor might be too thin due to process issues. If it's way too thin, it'll fail immediately and the die will get sorted out at test. If it's just a bit thicker, it might pass all production tests but fail after an hour or two of operation, or 100 power cycles. If it's just a bit thicker (where it should be), it might last for 20 years and a million power cycles. Everyone in the semiconductor industry would love to figure out how to eliminate these early failures. No one has found a way to do it.
"migrant farm workers" likely aren't the major source of contamination. Think bird shit, coyote shit, rabbit shit. There's no water treatment for field water - so the water coming out of the sprinklers is pulled straight out of the ditch/river which may be contaminated by the feedlot upstream. All of which are sources of "fecal contamination".
I strongly believe in Solar Power - especially in Az. We don't have much in the way of wind resources (and I hate the view of windmills anyway), but sun we've got an abundance of. Solar and Fossil fuels are neck-and-neck for 30-year amortized costs, but solar should win simply from a public health standpoint.
However, I really don't believe complex law should be ensconced in the State Constitution. The entire US Constitution is four handwritten pages long. The first ten amendments fit comfortably on another. This amendment is four pages long by itself. If this was coming up in the legislature, I'd probably support a version of it (using a definition of "clean power" that includes existing hydropower and nuclear power).
>>> will you discard it and build a new one to manufacture a new chip?
Generally, yes you will. A large part of the cost of the factory is the machines in it - and generally they all need to be replaced when you move from one process node to the next. Let's say you spent $1B to build a 40 nm fab. You start building state-of-the-art wafers in it, and (being a good businessman) after a year are running it near 100% capacity. Next year, the bleeding edge wafers need to be at 32 nm. Your choices are: 1. Shut down production, spend 6 months retooling for 32 nm, then re-open. Cost: Six months of production plus new machines. End result: One fab producing 32nm wafers. 2. Keep the plant running, and build a new 32 nm fab. Cost: New fab with new machines. End Result: you still have the old fab cranking out 40nm wafers which everyone who doesn't need the bleeding edge will be buying for the next several years. In fact, you might have 55 nm, 40 nm, and 32 nm fabs all running in parallel. And those state-of-the-art 250 nm fabs from 20 years ago? Some are still running, putting out dirt-cheap wafers for people whose needs are met by low-performance, dirt-cheap ASICs.
So, why don't you complain to the "high-end and actual workstation laptop" manufacturers? If they build a laptop intended to dissipate 200W all day long, perhaps they should equip it with a charging solution capable of 200W rather than relying on a charging solution incapable of greater than 100W?
It pissed me off on my last flight to Korea on a 787, when the flight attendants hit the switch and all the windows went dark. 9 hours sitting next to a window that I can't look out of. If you people want to sleep, BUY A PAIR OF EYESHADES.
I believe that QC will only attack the "large number" asymmetric algorithms - RSA, ECC, etc. I believe that symmetric algorithms such as AES aren't as susceptible to QC attacks - Grover's Algorithm cuts the effective key length in half (AES-128 could be brute forced by a QC as though it had a 64 bit key; AES-256 effectively eliminates that problem).
Of course, without the asymmetric algorithms it's really tough to set up a secure session, especially with a server that you don't know.
You have no idea what you're talking about, do you?
You've got all the right words there, but completely the wrong concepts behind them. You do realize that ALL of the data shipped around via HTTPS is encrypted with symmetric algorithms, right? And that asymmetric algorithms are used to create and agree on the symmetric keys to be used for communications, right?
I'm also running a Phenom II in my main house machine. Works fine with the things I do with it - browsing, CD ripping, etc - but I use a much more modern processor in my work machine...
I was going to build a new machine this winter, but the price of GPUs kinda discouraged me from that endeavour.
