What exactly does abstract reasoning have to do with fulfilling those kinds of interaction needs?;-)
On a slightly related note...
Q: Recent polls have shown a fifth of Americans can't locate the U.S. on a world map. Why do you think this is?
A: Oh, your questions seems to be rhetorical - you do already know the answer!
That said, when management decides they can just keep using the quick-and-dirty cable out the window solution instead of paying for something proper they will soon get into trouble. When I took over the network at my workplace after about 10 years of symbolic funding, there were flat layer 2 networks spanning some 120 WAN sites over 480 square kilometers using multiple radio hops and FreeBSD based tunnels for encryption. Very cheap, very clever... and very useless for getting any actual work done. When management finally woke up they had to spend a LOT of money to rebuild everything from scratch, a process that has taken tree and a half years and still isn't finished.
Every company needs a hacker, but they also need someone in charge with enough technical insight to know when to let loose that hacker and when not to.
Last time I checked the recommendation from VMware was not to use NTP on the VM at all, instead use VMware Tools to sync time with the VMware host and make sure the host itself is synced using NTP. Windows is (ofcourse) more difficult since AD insists on using its own time synchronization. Which is why we keep a few physical domain controllers. PBX/voicemail servers are also physical, everything else is virtualized.
Also, VMware recommended we virtualize Vcenter since our cluster is split between two physical locations since those two locations share the same layer 2 networks. This means we can shut down one of the locations without anyone ever noticing. The VI client can be run directly against the host where Vcenter exists to bootstrap the environment, all you have to do is plan ahead for that scenario and test that plan once in a while.
Yes and no. Most brownouts are indeed caused by transport problems but very few power plants run at less than optimal capacity. Having one or two turbines down for maintenance is the way it has to be, it doesn't mean there's loads of unused capacity. Power plants represent huge investments so they have to run at optimal capacity.
Norway uses a lot of hydro power. During the summer, most of the electricity is exported via sea cables and during the winter we import electricity back from those same countries. From a consumer point-of-view this is madness because we end up paying more both for our own clean electricity during the summer as well as the "dirty" electricity during the winter, but the power companies that own the power plants it's a neat way to maximize the ROI. (An investment which, btw, was made using public funds before the gov't privatised everything.)
The power plants needed to replace all gasoline cars in the world with electrical ones simply do not exist and since there is no way to produce electricity that's both safe and environmentally friendly I have a hard time believing there ever will be. When some people even manage to raise issues against planting TREES you know it's going to be hard to make any kind of progress.
Not only is the heat wasted, you have to spend even more energy on getting rid of that heat because if the coolant gets too hot the engine will break. The irony...
This was (to a certain extent) true for carburettor engines, which is why everyone switched to injection as soon as the electronics became cheap enough. If you have a mechanical throttle in your car today, you're most likely an enthusiast or you live in Cuba. Or both;-)
1. Pump oil from the ground.
2. Distill it to separate into different amounts of various products such as diesel oil, gasoline oil and whatnot. They're all oils.
3. One liter of gasoline contains more potential energy than one liter of diesel oil.
4. Current diesel engines convert more of that potential energy into forward motion than current gasoline engines. (= "more efficient")
5. The remaining potential energy is wasted, either in the form of heat or in the form of fuel not completely combusted and disappearing with the exhaust.
6. The original article describes an engine that may use gasoline but mimic a diesel engine, which until now has proved difficult.
Americans...
Then what if this technology actually came along and completely obsoleted the diesel engine? Diesel would actually become the byproduct that nobody wants because gasoline is suddenly both cleaner AND more efficient. No doubt the politicians would ban the use of diesel for road vehicles if this was the case. Meanwhile, with the world already running out of oil, making "half of it useless" could make things interesting. Diesel power plants perhaps?
Actually, it's the other way around. Gasoline engines typically need higher RPM to produce the same torque as a diesel engine with the same cylinder volume. Modern diesel engines are usually tuned to produce max torque somewhere around 1500 rpm, for heavy trucks the peak can be as low as 800-900 rpm.
Not only that, the very first diesel engines actually ran on coal dust at rpms matching the steam engines they were designed to replace -- typically 100-150 rpm. Try THAT with a gasoline engine;-)
I wouldn't worry too much. Like most other silver bullets against piracy, this "technology" isn't meant to stop piracy at all, it's designed to suck money from the idiots in the media industries who can't get it into their thick heads that their business model has been obsoleted.
I fully expect that Windows 10 will include a micropayment system that requires you to enter your credit card information and pay a small fee every time you log in, print a document or send an email. Running non-Microsoft software will require additional licensing because such software is usually associated with either piracy, illegal hacking or deviating political views. If you don't have a valid credit card, you're probably a terrorist anyway.
I drew a line and plotted in the three 2 digit numbers my then-4-year-old was curious about. It took him about 10 seconds to grasp the concept and plot a fourth number in roughly the right place, and I'm not a teacher. Maybe you've been around a bunch of particularly uninterested 10-year-olds?

Q: Where do babies come from?
A: Why should I know where? Ask somebody else! I'd like to be judge next year, it's so funny to "test" people:-)

Now all you have to do is install a Trojan and skimming will be completely automatic.

Unfortunately, there is currently no free way to convert that energy into forward motion or pictures of naked women.
