It's perfectly sound marketing logic.

Explaining things to people who aren't up to speed yet is difficult and tedious; and in any even people don't have the patience to sit through explanations. So the obvious thing to do is to describe your product in terms that confuse everyone, equally.

The hospital didn't show that normal lagtime won't affect remote robotic surgeries. It looked for possible effects of that sort and didn't find any. That's a good result, but it's only the start of a process that might show that doing this is reasonably safe for patients.

The real world is much more demanding and uncontrollable than simulation. Remember the Therac-25 incident. Thorough functional testing apparently showed that the machine was perfectly safe; it didn't take into account the difference between testers and people who would actually be using the device every day. While you can never prove the non-existence of some unknown and unpredictable factor, that doesn't mean that a long and critical search for things you might have overlooked is useless.

I think it's pretty amazing that spacecraft can survive at all out there, given the sort of particles flying around - individual cosmic rays with the energy of fast-pitch baseballs. Thankfully, particles with such high energy have tiny cross sections (they prefer to move through matter rather than interact with it), and when they do hit something and create a shower of particles, most of the progeny is likewise super-high energy and will most likely just move through whatever it's in.

It's more interesting when they strike the atmosphere - each collision creates a new shower of other high energy particles, more and more, spreading out the energy as they descend. In the end, detectors on the surface over an area of dozens of square kilometers simultaneously pick up different pieces of the same cascade kicked off by a single cosmic ray collision.

No, fines for violating export laws.

Being slapped with massive fines is usually pretty good motivation for a company. And given that the US spends nearly half of the world's total military spending, and the EU a good chunk of the rest, simply "hopping overseas" and choosing to serve other markets isn't exactly the smartest of plans, financially.

It's idiodic for a company to wilfully risk sales of hundreds of thousands of units per year to NATO to sell a couple hundred units to Russia. Russia's economy is barely bigger than Canada's. And less than 80% the size of Brazil's.

You could start by reading more than the first paragraph.

1) They don't have "zero" capability, but they have way too little - only a few hundred modern imagers.

2) They have tried to buy them off ebay before. And it led to arrests. It's illegal to export military-grade night vision equipment without a license, and apparently sites like ebay are well monitored for potential violations.

The same is true of university exams. My undergraduate exams, for example, mostly required that you answer two of three questions per exam. To get a first (for people outside the UK: the highest classification), you needed to get 70%. Most questions were around 40% knowledge and 60% application of the knowledge. If you could predict the topics that the examiner would pick, then that meant that you could immediately discard a third of the material. To get the top grade, you needed to get 100% in one question and 40% in another. This meant that you could understand a third of the material really well and understand another third well enough to get the repetition marks, but not the understanding ones and still get the top grade. This meant that you could study 50% of the material and still do very well in the exams, as long as you picked the correct 50%. And some of the lecturers were very predictable when setting exams...

What jobs do you imagine existing in 10-20 years that don't require some understanding of programming? I thought my stepfather, as head greenskeeper at a golf course might have had one before he retired, but it turns out that the irrigation system that he had to use came with a domain-specific programming language for controlling it. A lot of farm equipment is moving in the same direction. Office jobs generally require either wasting a lot of time, or learning a bit of scripting (hint: the employees who opt for the first choice are not going to be the ones that keep their jobs for long). Jobs that don't require any programming are the ones that are easy to automate.

But, of course, we don't need to teach our children to write. After all, they can always hire a scribe if they need to and there really aren't enough jobs for scribes to justify teaching it to everyone.

Why would I be stuck with the connector? For one thing, you can easily install adaptors - even if you'd rolled out USB A or B sockets, they'd still be supported everywhere and you can buy adaptors very cheaply. The main problem with a USB A socket (which is really the only one of the previous ones that you'd consider for charging) is the low power - it can only provide about 10W, even if you have some adaptor. USB C can provide 100W, and 100W seems like enough for a DC supply for quite a while.

But if I'd rolled out USB A sockets in 1995, I don't think I'd object strongly to replacing the faceplates on the sockets with USB C ones in the next five years, if the wires in the wall could supply the required power.

I have yet to see a USB-C connector yet, and I am usually a first adopter.

No one you know has a MacBook Air? Most of the next generation of mobiles are going to have USB C (Apple and Google are among the bigger backers), so expect to see a lot of them appearing.

If you connect one of these to the existing AC main, then you're just moving the well wart into the socket. You still have one AC to DC converter for each device, and that particular device can only provide 2.1A at 5V, which is well below what USB-C supports (no charging a MacBook Air from it, for example).

Comment: Re:EU food ban? (Score 3, Informative) 83

Yeah, but they "cheat" a lot - for example, Belarus has made a mint serving as a reshipping platform for European goods. And for some reason they left Iceland off their list even though we supported the sanctions against them. Still, it's caused major food price inflation (unsurprisingly). Seems kind of a weird way to punish Europe, it seems obvious it's going to have a lot more effect at home than abroad - Russia's trade in food goods with Europe makes up far more of its imports than Europe's trade in food goods with Russia makes up of its exports. But I guess they didn't have a lot of options for "retaliation". I mean, Gazprom is already nearly going broke as it is, turning off the spigots would have rapidly ensured that it did. Oil and gas make up half of their government budget and 2/3rds of their exports - it'd sure punish Europe, but it'd also be economic suicide.

I think they're really hoping that the sanctions will just expire and they'll be able to go back to raking in western capital again. Because if they don't expire, barring some huge unexpected oil price surge, those reserve funds are going to dry up. They expect it to be down to under $40B by the end of this year. What they're going to do when it runs out, I have no clue. They need dollars and euros to buy the goods that their undersized industrial sector can't manufacture. China's a help but not a solution; they don't have the lending power of the US or EU to begin with, and their goal seems to be more exploiting Russia over the situation than offering friendly aid. For example, they got Russia to agree to the cutthroat rates on the proposed "Power Of Siberia" pipeline that they'd been trying to get for years and to let them own greater than 50% stakes on fields inside Russia. They got Russia to sell them their most advanced air defense system despite the objections of the defense industry over concerns that China would do what they always do with new technology - reverse engineer it and then produce it domestically. But who else are they going to turn to? China's basically becoming Russia's "loan shark". And at the end of the day, if it came down to it and China had to chose between the Russian market and the 20-fold larger market of the US and EU? It's not even a contest.

Main stream media routinely lies to people not just in the advertising it sells but now in not-news it peddles. Those liars do not do nothing for free. That time gap between the report release and spreading the lies, time enough to approach candy corporations with spend some more on advertising and we will spread this not-news story far and wide.

Reality, people want to hear the truth from news, not more lies, ask people what they want to hear and by far the majority will say the 'TRUTH'. Forget the lies about main stream media saying they tell people what they want to hear, they tell the majority of people the lies a minority of people pay to be told. A more treasonous bunch you could not expect to find anywhere than in the corporate boardrooms of media empires.
