An interesting note is that we do have cockpit video of the SpaceShipTwo disaster because no such union was involved, and it did seem to result in useful information. Still not sure which side of the issue I land on. I know I wouldn't want to be videotaped 24/7 at work.
I bet your work doesn't involve being responsible for the lives of hundreds of people.
We're trying to explain inflation and the motions of stars orbiting galaxies not matching our naive model.... couldn't a non-linear gravity model explain all this without the dark energy/matter hocus pocus?
Gravity is non-linear, or maybe you didn't notice that distance is in the denominator? It's linear in mass but really very non-linear in distance. m1*m2/r^2. Not even remotely linear.
To review: double m1, you get double the force: linear in m1. Double m2, you get double the force: linear in m2. Double r and, WHOA NELLIE you get 1/4 the force: massively (pun intended) non-linear!
Heck, he could, you know, rent an OFFICE to conduct his business from that has connectivity. There are tons and tons of incubator spaces that would be happy to have his business.
I've conducted business from home. It sucks. There are many good reasons to separate work and home.
With Prime and a few dollars i have to wait only a day.
It's actually far better than that. With Prime and a few dollars, I can avoid going to the mall entirely and wasting the two hours that horrendous experience entails. All-in-all, it's a profitable proposal for me, as time is precious.
When the need for having something immediately rises above my personal cost threshold for a trip to the mall, well, that's still an option. But in the name of all that is holy, why would you ever step foot in one of those things otherwise?
When malls first opened (yes, I'm that old), they tried to attract customers by making the experience a rich, enticing, special one. You had good restaurants. Calm, quiet environments. High-end department stores as well as fashion boutiques. Sales staff that dressed well and spoke proper English. Now it's noise, bling, distraction, horrid food, snotty sales staff with slacker attitudes that match their poor verbal skills, and self-checkout tellers. Thank you, I'll stick with an on-line retailer for commodity items. And when the malls die, it will not be a great loss as the positive shopping experience of yesteryear is gone already. To paraphrase the parent poster, good riddance to the modern malls.
I get that they want to keep these things close to earth and away from airports. I don't get why you need to be able to glide a plane onto the runway during an engine failure in the landing pattern when you're probably flying a drone that is incapable of gliding at all and which is multi-engine besides.
Because they have certain tools at their disposal. They have the private pilot's license. They have the medical certification. They know how do to handle those things. No additional bureaucracy is necessary -- and that's a mightily good thing. If they had different requirements ("sedentary medical certification" for example), then that would represent a heapload of additional work for them, cost for the taxpayer, and, as this is an EXPERIMENTAL PROGRAM, potentially wasted effort.
Far, far, far better to use the tools they have available. Yes, the regulations might not appear a good fit, but they are as close as possible given the requirements surrounding piloting a remote flying vehicle.
Being piggish about the mismatch of regulation versus actual requirement is not seeing the larger picture.
Really? I used to get 30 mpg when everything was in perfect tune. The trick, though, was it was very easy to fall off of that global optimum, so you had to keep continually tuning and tweaking if efficiency was the goal. If you didn't care so much, then it was a wonderfully reliable car. And, sure 18 mpg was easy to obtain.
The best theory I've heard is the follows (don your aluminum-foil hats!) --
Suppose you were a terrorism-for-hire organization, or a straight-up terrorist organization that was planning another big strike against a major superpower. Either one works for this theory. And suppose you had some new, amazing high-tech way of taking over a 777 by remote control. What would you do to either (a) test your system, or (b) impress a potential client? Such an ability would be HUGELY valuable, but only if it remained secret. You'd probably select a flight operated by a developing country that would not nominally have been under the same level of scrutiny as one from the first world, and one that could quickly be taken out of normal radar coverage. You'd take the plane over, disable its communication, move it about against the pilot's will (but still within radar range so that the demonstration could be recorded), and then send it off to crash well outside of radar range in a very deep part of the ocean where it might never be found, so evidence of your nefarious actions would not come to public scrutiny.
You'd be able to demand a pretty high price in the elite international terrorism market with such a demonstration. So while the act of diverting MH 370 might not in itself have been an act of terrorism, it still might have been executed by terrorists.
It's far fetched, yes, but it fits the facts better than any other theory I've heard. (Suicide by two non-suicidal pilots? Fire that magically disables communication without affecting navigation? Hijack with modern hardened cockpit access? Etc.)
The solution is actually pretty simple: use Google. To understand what time it is in a different city, use
time in London
To schedule a multi-timezone meeting, have the leader declare, e.g., "the meeting will be at 7AM London time", and allow each participant to figure out when that will be for themselves using queries such as
time in New York when 7am in London
Our company has been using this method to organize our international meetings with participants from five distinct timezones for some years now. Works like a charm.
As (another) analog designer who happens to be in the middle of designing a mixed-signal board, I can assure you that the right answer depends on how sensitive your analog circuitry is, and it could very well be that the answer is, "enough to drive you crazy trying to eliminate the interference."
Proper shielding of analog circuitry from digital interference, when the two are in close proximity, is really very, very hard. That's why you see all of the high-end audio cards have either (a) full faraday cages (plus careful PCB layout technique), or (b) are external to the computer case, or (c) both.
Five unshielded single-ended lines switching 1.8V at 208MHz that might not be properly terminated? Sounds like a powerful AM transmitter to me if my uV to mV level analog traces are anywhere near them.
The biggest contribution from the massive levels of research on AIDS is not curing the disease. That will be wonderful when, and if, it happens. The biggest contribution will be that, as a result of trying to cure AIDS, we have learned immense, really truly immense, amounts about the immune system and it's incredible intricacies.
And, guess what? Ultimately, it is the immune system that keeps your body free of cancer. Cancers happen frequently in your body, and the immune system beats them down. When it fails at that for some reason, only then does clinical disease happen. I've heard it said that most people have 6 or so small cancers in their bodies at any given time, all being properly managed by the immune system.
Understanding the immune system, because we have been trying to cure a disease of the immune system, will eventually do more good for human health than any other single effort since the invention of antibiotics, with the possible exception of magnetic resonance imaging.
But let's look at the GP's assertion about money. The National Cancer Institute's budget appropriation for FY15 was $4.9B. They're the part of the NIH that sponsors cancer research. The National Institute of Allergy and Infections Diseases, the NIH that is charged with fighting AIDS, had $4.3B appropriated for FY15. Even if we assumed that the entire NIAID budget went to AIDS (and it does not), the NCI has a bigger budget. So the GP is just flat out wrong with his initial assertion: much less research effort in the form of NIH extramural support is spent on AIDS than on cancer.
I'm all for this sort of noodling around, but it seems, ah, a little low-brow for such an esteemed bunch of folks, and I say this with two of my three degrees from MIT whence the research came.
From the article, "While it at first glance might appear to be a glorified toy..." and that is certainly the truth. Dispelling that impression is in no way helped by the audio track on the released video where someone intones "pewnnnnnnggggggg" as the vehicle is released, making the same sound that a kid would.
I'm sure there's serious science buried beneath it all, somewhere, but it isn't evident in the article, nor in their materials apparently released to the public.
"Out of all the hundreds of millions of Facebook users, which ones look the most like me?"
I'd rather ask, out of all those people which ones look like Mark Zuckerberg enough to pass for him at the corporate headquarters? Just to make a point.
And subtract retirement, and insurance payments, etc., after all that, no one is going to get rich on EUR 90K per year. Not going to starve, but not going to get rich, either.
To present some perspective, as an employer in the US (yes, I realize things are probably different in Germany), if my personnel budget is USD 90K, that means my employee is getting only USD 61K in salary. The rest goes to various overheads that I pay to support the position.
I run a small scientific laboratory (3-5 people depending on the season) that is very much like a startup. Our primary product is scientific output, and stability is paramount for us, even though we're small. We have standardized (by edict from me, The Boss) on one version of Word, one version of OpenOffice, one version of Matlab, one version of Windows (well, two, because we have some older XP systems used in data collection), etc. The versions selected for standardization shift, but only slowly (ie, it's about time to update from Word 2003, but we'll probably stick with Word 2010). Although I use Fedora for my desktop and laptop systems all of the other Linux boxes are CentOS.
For me, Fedora's 18 month support cycle is really too short... so I end up going well past EOL and only update to the most recent version when critical things stop working well.
PCBs (printed circuit boards), plastics used as insulation, coatings, and physical parts (card holders, connectors, IC bodies, fans, etc.), paint, capacitor innards (electrolyte and the aluminum), lithium batteries (boom!), and so forth in the servers themselves. Then there's the cabling and connectors between servers and between racks, possibly the floor and ceiling materials, lots more paint, any structural materials used to create the room, etc. Perhaps not as much as in a residence or office, but lots and lots of potential fuel.
Really? Fired? Funny, 'cause I'm the boss. If we had an application running under Windows 95, _and it worked_, there would be absolutely zero reason to do anything with that machine when there are other, more important, ways to spend our time. Granted, that hypothetical machine would not be on the net, 'cause we aren't stupid.
The real machines we have running XP, run our experiments (and they have never been on the net for other reasons); until such time as the boxes die, they will continue to run our software, and continue to run it under XP. And then, they will be replaced with the identical backup hardware we have, giving us enough time to get a grant funded to have someone port the code to a more modern system. Until then, we have science to do. Computers, in my lab, are like any other tool that is to be used to collect data and advance knowledge -- pens, screwdrivers, oscilloscopes, whiteboards -- and are not an end unto themselves.
Didn't work for us. We have an application that has been developed over about 10 years in VB6. No one has the budget -- either in finance or time -- to port. We looked at Wine as a plug-and-play replacement for XP and the application did not work correctly, 100%. The application is mission-critical, making anything less than 100% compatibility a non-starter. So we're stuck with XP until the next big grant comes in and we can afford to pay someone to port it to a more modern system.
Don't get me wrong, Wine is an impressive amount of work, and my hat is off to the brave folks who have put so much time and effort into it. It just isn't good enough for our needs, unfortunately.
And two little letters "UK" at the start of the headline would have eliminated all ambiguity. The headline is an example of prima facie editorial failure.
A large reduction in taser use, higher reports of police brutality, slightly higher use of lethal force?
My crystal ball says that there will be an unexpectedly high level of malfunctioning video equipment, triggering a big-money follow-on contract with the manufacturer to correct the problem. The follow-on contract will achieve a just-above the threshold of measurability improvement in reliability. Then, later, when the current brouhaha has been forgotten, the cameras will be left to accumulate drawers with the official evaluation that they were fundamentally defective and so no longer required. And, of course, the real problem will be intentional damage to the equipment caused by the officers required to wear them who have something to hide.
Aren't these folks just looking for a Karadashev Type II civilization? That was defined, oh, about 50 years ago, now. By an astronomer.
Talk about not bothering to look at what people in a given field have done before impinging upon your own self-important program. If anyone bothers to read the linked article (I do not recommend wasting your time), it's full of blatheringly idiotic statements about how major advances in science come about. I'm a scientist, in a different field, and we are pushing the boundaries as hard as you can imagine. We look at anything and everything that we can find that is relevant to help us succeed at our, frankly, audacious, high-risk work. And there are one or two people in the field who are blathering idiots like this who keep on talking about pie-in-the-sky visions they have for how things should work... and they contribute nothing. Meeting after meeting, they provide the same drivel without doing any work, rehashing old ideas. Sure, they have entertainment value, but given the level of commitment and intensity to success that others have in the field, they are an unnecessary distraction and serve only to dilute the efforts, not build upon them.
Yes. French was the international language 100 years ago. English was (at that point) an also-ran.
Interesting observation: in modern-day Poland, when you ride the train, there are multi-lingual signs instructing on how do do things like open the windows or operate the toilet. The signs appear in Polish (it's Poland, after all), German (much of Poland was Germany and vice versa), Russian (it was under the Soviet sphere of influence), and French (the international language). No English.
