Actually, they haven't. You can clone the mag strip, but most cards now register that they have a chip. The bank won't authorize it by mag strip if a smart card is present; you can still copy the mag strip and use it for offline attacks (e.g. use it to buy crap through Paypal).
A smart chip--the type of tool embedded in an EVM card--is a miniaturized computer with an I/O protocol. When attached to the reader, it's powered up and accepts commands. It doesn't release the key, and only performs digital signing within its own memory space and returns the result.
Some implementations in early chips used DES, which has cryptographic weaknesses. It's possible to crack DES in a few hours and recover the key by analyzing signed known-plaintexts, allowing for cloning. Most early implementations used 3DES or RSA at a currently-unbroken level, making this attack impossible.
Amusing: SD cards are also microcomputers and communicate over an I/O protocol. Direct access to SD card NAND is not possible; loading an operating system onto an SD card and making it perform computations is possible.
That is. In that case, you've adulterated the drinks without her knowledge. That's a legal distinction that can counter any argument in any non-retarded legal climate--that is to say: if the local courts determine that women in general go out, get drunk, and accept the consequences as a matter of culture (because "let's get drunk and screw" is a thing as much as "I was drunk when I said that!"), they might or might not claim the venue implied tacit acceptance of sexual advances while drunk; if you knowingly and purposely conceal the administration of an intoxicant to a woman, she hasn't made a consensual decision to become intoxicated, which is a hell of a lot more concrete.
People are arguing whether or not hooking up while drunk in a bar is a crime against the drunk party(/ies). In America, the normal cultural answer is "no", which is perplexing but still a factual description of how people perceive bar hopping. Nobody's been insane enough to argue that drugging someone without their knowledge isn't date rape.
I actually injected psychiatry into a diet thread. It's still medical; you apparently don't have any experience dealing with Cluster A personality disorders.
The most likely means that if you charge the electrolyte to (for instance) 3.4 volts it will be stable, but you can't charge it to more than 3.5 volts or less than 3.3 volts.
This is a desirable attribute of a battery. It's what makes lithium batteries so much better than NiCd and, to a lesser degree, NiMH: they only have high voltage when within small percentage of their maximum state of charge; they hold near-flat voltage until chemically-exhausted; and they quickly fall off when discharged.
Physically, a battery outputs higher voltage when a larger amount of its chemistry reacts at once. More electrons ready to go on one end, more positively-charged matter on the other. As that tapers down, the voltage reduces, and so does the current. As the cell loses its capacity to produce a charge difference at the given rate, the voltage falls further.
Lithium Ion cells exhibit a dramatic increase in capacity to produce a charge differential at high state-of-charge. After that, they hold relatively-flat, which means you can expect a stable voltage until they flat run-out of material to react (low state-of-charge). Then the voltage drops off suddenly.
That behavior is one of the most-desirable aspects of Lithium batteries. Are you telling me JBG is suggesting a predictable, near-fixed voltage is a bad thing? Should we re-engineer the United States power grid to supply a voltage that swings between 80V and 145V over the span of several hours every day, instead of holding reasonably-close to 117V at all times?
half your post focuses on your assumption that he was talking about voltage stability over a range of charge levels. That's your assumption.
It's the reasonable assumption. You haven't proposed one that is more reasonable, unless you're suggesting JBG is just an idiot.
Good thing we don't live in a world where it's common to have temperatures below 10C.
It's still a wide range, and it's the range at which we operate most of these batteries in most contexts. One of the wonderful things about water is it's liquid across a wide range of temperatures, allowing life across the majority of climate zones on planets in the habitable zone of a star--such as Earth. That's only about a 100C range; and cats are uncomfortable above about 64C ambient, while the hottest survivable body temperatures of animals don't go above 42C. The listed world-record ambient weather is around 58C.
Lithium batteries are stable in that range, and nearly 100% of all Lithium battery use cases are centered in that range (room-temperature, around 15C-25C), so it's not likely he's talking about temperature range--unless he's an idiot.
the problem with operating a li-ion at high temperatures isn't that it "loses capacity" as you seem to think the problem is,
Between 10C and 60C, lithium ion batteries have above 90% of their capacity. Above 60C, they have over 100% of their capacity and a dramatically-shortened lifespan. Their capacity is 100% at a temperature of 60C because that's expected, safe, non-destructive operational temperature; it's 103% at 70C because they're operating outside safe temperature margins, even if they do squeeze out a little more juice that way. This should be obvious, else 70C capacity would be 100%--again, information you can infer from context.
He didn't say they have a narrow stable voltage range; he said they have a narrow window for a stable voltage range. There is a window within which they are in a stable voltage range; outside that window, their voltage range is unstable. That window is 90% of the battery's charge capacity.
Second, a stable voltage is a desirable characteristic of a battery. You want a stable voltage. You want it to be 4.2V, or 3.3V; you don't want a battery that may be something between 3 and 5 AA cells. Remember how old NiCd power tools would start to slow down 1/4 of the way into their charge, and were notably-weak half-way in? That's what happens when you don't have a stable voltage range. Having a narrow range of voltages is a good thing. Having a stable voltage range over a wide window, which Lithium Ion batteries do, is an exceptional quality in a battery.
Third, the question was about failure. The OP was asking why Lithiums fail suddenly--why they sharply lose capacity at full charge.
Yeah, well, I'm in America, this happens all the time, nobody gets arrested, and DJs in bars universally encourage people to drink more alcohol by suggesting they're going to take some hot drunk cheerleaders home tonight. I've already made the argument and literally nobody cares. The same people will argue that it's wrong and rape on Facebook or in an open Internet forum, and then forget they said that when Saturday Night rolls around and they're buttfucking two 20-year-old underaged drinkers--after showing up to the bar at 11pm so the girls are already pretty into it and they don't have to wait for them to get drunk (yes, that's a popular strategy).
VNC is slow because it is essentially a continuous screenshot-encode-send desktop stream. RDP sends draw commands and keeps bitmap buffers on the display end, which is why it's a hell of a lot less-laggy than VNC. You should see the horrendous shit that happens when you use something like TightVNC hexagon RLE (high compression) over an SSH tunnel on local gigabit LAN, versus RDP with TLS encryption over wifi.
Basically, VNC has to draw a buffer on the originating end, render it to bitmap, and send that (possibly segmenting and compressing the bitmap) to be drawn to a buffer on the display end. RDP forwards draw commands and other graphics back-end, skipping the entire drawing and rendering to bitmap step on the originator.
Nobody cares. I've had this discussion before. I got women involved and they started arguing that it's their fault if they get fucked while blind-drunk. At a point I just gave up and went back to playing video games.
In most respects the major freedoms we lost were the freedom to use our power to take away other's freedom.
There's a perception and, in some cases, a correlated reality that we've lost reasonable human behavior, too. Flirting is considered sexual harassment, depending on the context; in some cases, an action is either cute or creepy depending entirely on if the recipient responds well (e.g. "admirer" vs "stalker", same thing).
At my place of work, they explicitly put in training that sexual harassment doesn't occur on the first offense of non-tangible-action harassment. That means if you tell a coworker she's hot and you want to hook up with her, that's not sexual harassment unless you keep doing it; if you tell a subordinate you want her boobs and threaten her promotion, that's sexual harassment the first time it's even barely suspected.
Meanwhile, if 500 guys walk by a girl and each whistle at her once and are unaware of each others's existence, the Internet makes a video about it and calls whistling sexual harassment.
We've got a lot of experienced programmers here, and a lot of good and intelligent people. They've managed to create a colossal fuck-up and still believe it's well-designed and functional and doesn't need any real architectural rework. The one guy who's a giant nerd and actually studies beyond the ok-plateu is correlating all the fires to real understanding of architectural flaws; and of course the non-programmer (me) who studied project management is looking at the spread of expert knowledge and coming to the conclusion that that guy's right.
So probably 95% of programmers are idiots who found a chainsaw and think they know what they're doing because they can hit a tree with it.
A lithium ion battery at present has a very stable voltage between ~5% charge and ~95% charge. Outside that range, it has a sudden, sharp voltage drop-off (low state of charge) or a sudden, sharp voltage increase (high state of charge). The 100% state-of-charge is saturated, technically: you can't force more charge into the battery. That means that top 5% is really the top 5%, and not an artificial limit.
That implies that 90% of the battery's run time also supplies a stable voltage. That's a pretty wide window for a stable voltage.
Lithium ion batteries are also stable at a wide range of temperatures, and retain over 90% of capacity between operating temperatures of 10C through 60C; below that, they drop off rather-quickly. Because temperature of operation is typically acceptable and the context was not cold-temperature operation, it's unlikely he meant temperature window.
By the by, people who can't pick up on context in conversation as such are typically unable to function. They're perpetually-confused and incapable of understanding what's happening around them. Such people are generally autistic, although in mild cases we just cal them idiots. These people are usually good at understanding material, concrete things, but not at understanding conversation (and, of course, terrible at picking up social cues from the contextual side-channel).
You make an entire pot of 10 cups of coffee in one go by putting a scoop of coffee in a paper filter, pouring in water, and turning it on. Then you pull that out and throw it away. Keurig can give you coffee in 20 seconds instead of 4 minutes.
I was trying to push through some patches and updates to weston to supply weston-rdp as a back-end. Combine weston-rdp with Xwayland and an X11R6 session manager wrapper and you've got Xrdp working again.
So what next? Get lightdm integrated with weston-rdp as a session manager back-end and stick the Xrdp proxy server up front to call lightdm as the session manager. Wayland can switch session managers without tearing down, so Xwayland and Wayland clients can switch to your console Wayland display or to weston-rdp on command--meaning you can pull up your console session over RDP.
Can we see 18.04 supply an RDP service we can enable on port 3389 that gives you lightdm right up front, and lets you disconnect and leave the session running such that you can reconnect to it over RDP or from console?
For most of the human race, a reasonable amount of fiber (with enough liquid consumption) helps to promote digestive transit time and softens stool.
High amounts of fiber are known to cause constipation (for some individuals, excess fiber causes diarrhea). I suspect humans are relatively well-adapted to consume fiber in varied amounts with relatively-regular intake due to being omnivores; however, individual variation is apparently a thing.
Are you serious? Do you eat food daily? Are you on some sort of strange liquid-only diet?
Apparently the fermentation stage (early part of the major intestine digestion phase) is... efficient. I also don't eat a lot of fiber, and my body can absorb literally anything else that constitutes "food". Fats, carbohydrates, proteins. Bile is made up of cholesterol, and much of that is re-absorbed; the only thing you eat that's actual food and doesn't get sucked into your body or fermented by gut flora is insoluble fiber.
My main problem is increasing fiber intake shortens transit time to as little as 8 days in the extreme. 8 days with that much fiber is one hell of a lot of fiber.
Most people are better-adapted to consume a lot of plant matter. I'm not a unique case, just a rather extreme one. I suspect part of it is from simply not eating a lot of fiber ever in my life; have we tried putting Inuit people (whose main food source is blubber) on high-fiber diets? When you have genetic and environmental factors, combining the two leads to some pretty ludicrous outcomes--like people who are genetically-prone to Cluster A personality disorders can be largely well-adjusted introverts, or they can be raised by crazy parents and grow up to be schizotypical wingnuts who eventually try to get into Congress with a backpack full of hand grenades to save us from the Liberal Muslim FEMA Conspiracy.
Too many people are fallin into the fruits-and-vegetables meme every year. These types of foodstuffs tend to be mediocre in nutritional value, high in sugars, and heavily-imbalanced in nutrient profile. Generally, fruits and vegetables overload one nutrient (magnesium, calcium, a particular vitamin profile) and are anemic in another, requiring a complex and varied diet to obtain a complete nutrient profile; it's incredibly-common for mostly-vegetable consumers to end up deficient in a critical nutrient. For some nutrients, "high content" is relative, such as in the case of Calcium (broccoli is high in calcium, at some 4%-8% daily value per serving).
By contrast, animal products tend to have a broad and balanced content of most minerals, and are a better source of most vitamins. Animal products are an exclusive source of human-metabolizable B12 and supply a form of Vitamin A six times as active as Beta Carotine (the most-potent plant-source Vitamin A vitamer), while also providing significant levels of magnesium, sodium, calcium, potassium, silicon (barely-available from plant sources), sulfur, iron, phosphate, all B vitamins, Vitamin K, and a broad span of fatty acids (Omega-3 and -6, notably).
Plant foodstuffs are a near-exclusive source of the primary Vitamin C, which enables many biological processes and provides chelation of heavy metals such as lead and mercury. Animal sources of Vitamin C include certain organ meats such as goat liver, and only supply a small quantity. Vitamin E is also more-common in plant foodstuffs.
High-sugar and high-starch diets lead to diabeetus and heart disease; low-fat diets lead to lowered testosterone levels. Most people are fairly-tolerant to dietary fiber, although there are many fiber-sensitive individuals who experience severe constipation from excessive fiber intake. Optimal human nutrition incorporates 25%-40% carbohydrate intake; high-quality carbohydrate sources provide high amounts of Vitamin C, and the next-best sources are things like Sweet Potato and Pumpkin which supply more resistant starch and less insoluble dietary fiber along with a broad and relatively-high-load nutrient profile.
Last time I ate any significant amount of fiber, I squirted blood after a bowel movement. Somebody did a study into "idiopathic constipation" (constipation, but we don't know why) and found that increasing fiber intake makes it worse, while decreasing fiber intake causes more-frequent bowel movements and less straining and pain. Sounds like "dietary fiber sensitivity" is a thing but nobody wants to claim you can overdose on fiber. My doctor says it's strange and recommends I eat more fiber and consume metamucil (?!).
The issue is one of ratio. I have a 2-3 week travel time. Bowel movements about 1 pound (fist-sized) occur every 18-26 days. At 25g of fiber, 5.5% of the mass of stool is fiber; dietary fiber supposedly absorbs water and increases volume, so may represent a greater volume of the stool, but not necessarily. At 25g of fiber per day after 14 days on a similar-mass stool, 77% of the mass of stool is fiber; and the fiber will absorb water from the surrounding stool.
In other words: high fiber (particularly insoluble fiber) in slow, long-fermentation stools where the stool size doesn't increase in proportion to the travel time generates an engineered wood material consisting of lignin pulp packed in a fatty binder, with the pulp hydrated to a consistency appropriate for engineered wood, and the water content of the fatty binder reduced by a wood pulp desiccant. The result is a relatively-large-diameter, rigid stool and anal tearing.
Resistant starch doesn't pose these problems; and soluble fiber does tend to ferment, although a sudden change in soluble fiber may produce similar symptoms because your gut flora need to proliferate to meet the carry capacity of the available food source. Some starch-heavy foods may induce constipation as well, though (bananas, notably).
Some people have this kind of fiber sensitivity with a 3-day travel time. I have no idea why, as you shouldn't be particularly sensitive to lignin build-up after three days.
Why do Lithium batteries suddenly fail after their useful lifecycle? "The present lithium-ion batteries have many drawbacks because they use a flammable liquid electrolyte that has a small window for a stable voltage range."
That's not what was asked. The flammable liquid electrolyte doesn't have jack-all shit to do with why lithium ion batteries suddenly lose capacity when they've been cycled too much. They lose capacity because the anode starts to degrade, pulling anchoring material off and giving no way to recharge the battery.
Lithium ion batteries have a wide window for stable voltage. They're known to start at a high voltage, quickly drop off after less than 5% discharge, and hold almost-level until below 5% remaining charge.
All jobs are like that. If you want to make a table, you need to invest a certain amount of labor-time using current technology to make a table. There's no way around that; there's only the capacity to schedule when the factory runs and how much output it has.
As consequence, if you hire people for work days 75% as long, one of two things happens: those people have 75% as much income or prices of the service provided goes up by 1/3. These are actually equivalent in terms of how wealthy the worker becomes when the policy of shorter working hours is implemented universally across the entire labor force: they get poorer.

Just like with civilian laws, there are some that are taken seriously, and others that are routinely ignored.

For some nutrients, "high content" is relative, such as in the case of Calcium (broccoli is high in calcium, at some 4%-8% daily value per serving).
By contrast, animal products tend to have a broad and balanced content of most minerals, and are a better source of most vitamins. Animal products are an exclusive source of human-metabolizable B12 and supply a form of Vitamin A six times as active as Beta Carotine (the most-potent plant-source Vitamin A vitamer), while also providing significant levels of magnesium, sodium, calcium, potassium, silicon (barely-available from plant sources), sulfur, iron, phosphate, all B vitamins, Vitamin K, and a broad span of fatty acids (Omega-3 and -6, notably).
Plant foodstuffs are a near-exclusive source of the primary Vitamin C, which enables many biological processes and provides chelation of heavy metals such as lead and mercury. Animal sources of Vitamin C include certain organ meats such as goat liver, and only supply a small quantity. Vitamin E is also more-common in plant foodstuffs.
High-sugar and high-starch diets lead to diabeetus and heart disease; low-fat diets lead to lowered testosterone levels. Most people are fairly-tolerant to dietary fiber, although there are many fiber-sensitive individuals who experience severe constipation from excessive fiber intake. Optimal human nutrition incorporates 25%-40% carbohydrate intake; high-quality carbohydrate sources provide high amounts of Vitamin C, and the next-best sources are things like Sweet Potato and Pumpkin which supply more resistant starch and less insoluble dietary fiber along with a broad and relatively-high-load nutrient profile.
Last time I ate any significant amount of fiber, I squirted blood after a bowel movement. Somebody did a study into "idiopathic constipation" (constipation, but we don't know why) and found that increasing fiber intake makes it worse, while decreasing fiber intake causes more-frequent bowel movements and less straining and pain. Sounds like "dietary fiber sensitivity" is a thing but nobody wants to claim you can overdose on fiber. My doctor says it's strange and recommends I eat more fiber and consume metamucil (?!).
The issue is one of ratio. I have a 2-3 week travel time. Bowel movements about 1 pound (fist-sized) occur every 18-26 days. At 25g of fiber, 5.5% of the mass of stool is fiber; dietary fiber supposedly absorbs water and increases volume, so may represent a greater volume of the stool, but not necessarily. At 25g of fiber per day after 14 days on a similar-mass stool, 77% of the mass of stool is fiber; and the fiber will absorb water from the surrounding stool.
In other words: high fiber (particularly insoluble fiber) in slow, long-fermentation stools where the stool size doesn't increase in proportion to the travel time generates an engineered wood material consisting of lignin pulp packed in a fatty binder, with the pulp hydrated to a consistency appropriate for engineered wood, and the water content of the fatty binder reduced by a wood pulp desiccant. The result is a relatively-large-diameter, rigid stool and anal tearing.
Resistant starch doesn't pose these problems; and soluble fiber does tend to ferment, although a sudden change in soluble fiber may produce similar symptoms because your gut flora need to proliferate to meet the carry capacity of the available food source. Some starch-heavy foods may induce constipation as well, though (bananas, notably).
Some people have this kind of fiber sensitivity with a 3-day travel time. I have no idea why, as you shouldn't be particularly sensitive to lignin build-up after three days.
Cleaning a Keureg is more time-consuming and still has to happen. Automatic drip is essentially cleaned by brewing an empty pot of white vinegar.

Why do Lithium batteries suddenly fail after their useful lifecycle? "The present lithium-ion batteries have many drawbacks because they use a flammable liquid electrolyte that has a small window for a stable voltage range."
That's not what was asked. The flammable liquid electrolyte doesn't have jack-all shit to do with why lithium ion batteries suddenly lose capacity when they've been cycled too much. They lose capacity because the anode starts to degrade, pulling anchoring material off and giving no way to recharge the battery.
Lithium ion batteries have a wide window for stable voltage. They're known to start at a high voltage, quickly drop off after less than 5% discharge, and hold almost-level until below 5% remaining charge.

All jobs are like that. If you want to make a table, you need to invest a certain amount of labor-time using current technology to make a table. There's no way around that; there's only the capacity to schedule when the factory runs and how much output it has.
As consequence, if you hire people for work days 75% as long, one of two things happens: those people have 75% as much income or prices of the service provided goes up by 1/3. These are actually equivalent in terms of how wealthy the worker becomes when the policy of shorter working hours is implemented universally across the entire labor force: they get poorer.
Inflation plus you're entering a higher risk group. Why does my salary go up year after year?
