Yes. The most effective GIMPS use of GPUs is currently trial factoring. That is basically brute force division of the candidate number by small factors, which can eliminate candidates faster than doing a full Lucas-Lehmer or probable primality test. The new prime was trial factored by numbers up to 75 bits long. The optimal bit depth to trial factor to depends on the GPU hardware, especially the double-precision to single-precision ratio. Trial factoring can leverage SP, while the current LL and PRP implementations on GPUs leverage DP. There is an active investigation of the feasibility and performance of a SP LL/PRP algorithm on GPUs. GPU trial factoring for GIMPS is largely coordinated through GPU72.
As for the non-GPU crypto hardware, someone could write an algorithm for FPGAs. The ASICs have no GIMPS utility that I'm aware of.
You're not alone. I've had the same experience. Anything flashing below 70 Hz or so makes me nauseous. When I bought my current monitor, I specifically found a flicker-free screen, which was a challenge five years ago. Apparently someone figured out if they synchronized PWM brightness to the frame rate it made the images appear sharper â" but it just gives me eye strain. Most TVs are still constructed this way, and I actively avoid entering stores that sell TVs.
Try wild strawberries: they are intensely sweet and flavourful compared to their farmed counterparts. Their farmed counterparts have been bred for size and shippability, and taste and eat more like a potato than the original fruit. Wild strawberries are the only exception I can think of though.
Ah, but regenerative braking does help you in hilly terrain. Trucks waste a lot of energy countering gravity in mountainous areas. Regenerative braking also doesn't fade or wear out with repeated use, so is cheaper in the long run. Regenerative braking is totally worth it for long-haul trucking.
The new Iridium NEXT satellites should be in place by the end of 2017. Nav Canada is going to use the ADS-B service to monitor northern air space starting in 2018.
With four Iridum satellites in range, it should be possible to do MLAT positioning even with the old ADS-B.
The programming laws for terrestrial broadcasters don't apply to online distribution, thus there are no "Canadian content" requirements for Netflix.
Personally I think we should scrap the Canadian content rules, though with the increasing irrelevance of terrestrial broadcast there's less and less point in doing so.
I would argue it's developers abandoning Windows and moving to Mac. None of the dozen developers where I work use Windows. We're all Linux and Mac, about half and half. I suspect that's why Microsoft created their Linux compatibility layer: to stop the exodus of developers.
Of the developers using Linux, it's a mix of people like me who have been using it for seventeen years and people who have only recently picked it up.
It's not a complete replacement though: the sales and marketing side is about half Windows, half Mac, and no Linux.
Below 10,000 ft, airplanes are travelling at less than 250 mph. At takeoff, it's closer to 175 mph for a jet like a 737. At less than a perpendicular angle, the rate of travel across a field of view is less than that. If a person holds their arm out they can point with a lot of precision -- it's a lot easier than tracking an object at the same distance with binoculars. Furthermore, you must consider being at a distance away from the airplane. The greater the distance, the slower the plane is moving and the easier it is to aim at. Pointing straight up is rarely the issue, but if you're a mile away and the plane is on approach at say 2000 ft, that's only a 20 degree angle. Sitting in the cockpit of a 737, a pilot can see the edge of a taxiway -- the vertical field of view out the window is quite good. The lasers involved in these incidents are often much more powerful than a pen laser pointer and are many are strong enough to cause permanent eye damage. Unlike an incandescent bulb, lasers lose very little energy on the way to their targets. It's like those idiots on the highway who blind you with high beams at night, only much worse -- and I've had my night vision temporarily ruined by headlights a couple miles away. Lastly, there are lots of metal bits in a cockpit to reflect the laser, and the windshields are often marked by micro-abrasions from dust and insects, which can cause the whole windshield to glow.
Why not for flight training? Fuel is the biggest cost in running an aircraft, and if you don't need the range, battery powered is fantastic. It's the same trade-off as with electric cars.
"Fuel grade" uranium can be very cheap, depending on the reactor technology chosen. For instance, CANDU reactors run find on unenriched uranium. CANDU can also burn thorium.
I think LFTR is the way to go, once the technology is fully developed, since it is much more efficient and produces far less waste.
The methanethiol they add to natural gas is about equally toxic. The use the different chemical so you know it's natural gas and not something else. Methanethiol occurs naturally in the body, so small concentrations are harmless. High concentrations are deadly. Methanethiol, like H2S, is heavier than air and it may pool in low lying areas.
I've only been gassed once. It happened earlier this year from a fumarole in a geothermic area. I breathed the vapours for about half a minute when the wind shifted and ended up with irritated lungs for the next few hours (my eyes were also sore, but that could have been due to the sun; I was already sunburnt). My breathing peaked in tightness about an hour later. I also had a sore throat. No pulmonary edema. I'm not sure if I lost my sense of smell or not at the time. I do remember some drowsiness shortly after. I figure the concentration was close to 100 ppm H2S. It doesn't take much.
Yes, the two are different. H2S has a slightly sweet aroma. Methanethiol (aka methyl mercaptan), another sulphur compound, has a more sour smell (it occurs in urine after asparagus). Both are toxic in high enough concentrations.
It sounds very English to me. Most of the words are Germanic in origin, except arm, whose Middle English etymology in this usage comes from Old French/Latin.
I would argue English's articles are not superfluous, since English has lost its noun declension beyond the genitive.

Ever hear of Canada or Russia? Both export far more oil and produce far more hydroelectric power.

And covered in hot grits...
Heavy rain made for poor braking effectiveness and fishtailing.

That depends on two things:
The OpenGL stack. AMD hasn't put the same effort NVidia has into making OpenGL fast. At the moment, almost every 3D program on Linux is using OpenGL.
The porting technique. Some of the games are Linux native, while others use an API translation layer, which includes every game coded against DirectX.
Canada is almost entirely chip and pin now.
Click on the route and drag to make a new waypoint where you want.
If you want to add another destination click on the + next to the departure time.
I use both all the time.

Depends on the nuclear plant. Bruce Power regularly wins SWAT championships.
Space has a terrible power!

Here is what it looks like from the cockpit. Are pilots bullshitting? Try driving a car down an unlit rural road at night with that in your eyes and report back to us.
A 1 watt laser is enough to flash the ISS. It doesn't take much.
Why not for flight training? Fuel is the biggest cost in running an aircraft, and if you don't need the range, battery powered is fantastic. It's the same trade-off as with electric cars.
It also depends on when you want to spend the money: Intel is currently a lot more power efficient.
I'm excitedly awaiting Zen though.
