Get Play On Linux http://www.playonlinux.com/en/, (your distro might distribute it). It comes with user contributed install scripts for a variety of games (from CD/DVDs, GoG, Steam, etc), which will download the version of wine with the best compatibility / least regressions for a particular title, install needed runtimes, do all the winetricks magic needed and install the games. I've installed a few old GoG games and some newer ones. I'm playing Skyrim through PoL now and it runs (with DLC, high rest textures, and a handful of mods) just fine. Give it a shot, even if you dont have a GPU that will run the highest end games, you can get most of the classics through GoG and install/play them with PoL.

All quantum means is that energy can only have specific values. Imagine a stereo with a volume knob that clicks between values, ie it can be 1, 2, 3, n, but cannot be anything inbetween those numbers. Now you have a quantum volume knob.

Temperature is a statistical property of matter that only exists once we consider things as a continuum. At scales where we consider quantum mechanics, a molecule has energies (kinetic, rotational, vibrational, electrical, etc) which can only take on specific values (quantized) and these values are specific to the atom/molecule to some degree (atom makeup, radiative properties, etc).

That probably doesnt help wtih the sub-0 part of the article, but perhaps it will help with the quantum part.

Your first statement is untrue. You can limit the number of backers in each tier you set up. If you can only accommodate a production run of 250 units, you can set the pledge tier that includes the item as a reward to only allow 250 people to select it. Sure, that will limit your funding if you limit the tiers,but it fixes your hypothetical problem.

There are no 12x area codes in the US, and switches are plenty smart enough to distinguish +1 yyy npa-nxx from 112. And furthermore, this is a mobile standard, and no-one dials US country code for long distance calls on mobile, its just yyy npa-nxx. You dont dial the 1 or +1 unless you are outside of NA and need to call back into the US (or just overly pedantic).

250 hours is the minimum for a commercial rating, the theoretical minimum for a job as a first officer at an airline. The practical minimum is dictated by the supply and demand in the job market and I have seen it vary between 1500 and 250 hours over the last decade and across different airlines. The 1500 hour minimum is a good thing. There are still jobs out there for the 250 hour people (part 135 freight) and this gives experience that they need to get on their way to an airline cockpit.

Disclaimer: I flew for a regional airline for 4 years, benefited from the 250 hr baseline (I had 600 hours when hired, 3100 when I left) and I completely support getting more experienced people into those airplanes.

The new game, Star Citizen, is slated to be what anyone who has played wing commander or privateer dreams it could be. Best of all, Chris cut out the publishers (EA owns the rights to WC) and is self funding this project. There are 20 days left in the funding campaign to meet the ambitious stretch goals. Contribute at kickstarter or the main site for the game.

Modeling.

Weather modeling (solving navier-stokes and a few other equations on a discrete cartesian grid or on a spherical grid in spectral space). Add in land surface models, ocean models, data assimilation, chemical processes, and then crank the resolution way up and you need a lot of power.

DNS (direct numerical simulation) -- if you want to simulate a fluid flow with turbulence and you want to resolve the turbulence explicitly you need to have a grid spacing in your model that is smaller than the kolmogorov scale. For some flows this may produce a grid spacing measured in millimeters. If you want any decent sized model domain, this produces a lot of grid points.

Monte-carlo type simulations -- i.e., run a simple simulation but do it 1e50 times to amass a statistical representation of the process.

and lots of other types of modeling. Basically if you have a set of partial differential equations that tell us something and you need to solve them numerically (no analytic solutions, etc) and need to do it on very large domains at high resolution and your neighbor grid dependencies are such that your problem is parallel, then a supercomputer is for you.

No reason this should be restricted to apple products as an android tablet would work just as well to view pdf files, but still, very reasonable savings estimate.

You dont know the FAA then. I have two headsets, a Bose X and a Lightspeed Zulu. Both have the same 1/4" plugs and the slightly smaller one for the mic, both transmit the audio to the headset, both have (various degrees of) noisecancelling microphones, both use active noise cancellation.

But.... one has been shown to conform to a technical standards order (TSO) and one has not. So I can wear one of them at work, and one of them I cannot. All the TSO is btw is some standards on how the headset performs in certain situations, but the mfgr has to pay for the testing and certification. Both headsets work great, in fact the non-TSO one works better, but since word came down that we were not authorized to use non-TSO equipment, I cant wear it.

Its entirely plausible that apple has gone through a special certification process, and others have not. Typical of the FAA the certification is restricted to specific models, so you couldnt do something like certify "android", you would have to certify a specific hardware model with a specific version of the android OS.

Sit inside an airline cockpit once in a while, the majority of planes cannot do what a G1000 can.

Charts absolutely are used. On an approach, both pilots will have the approach plate (paper or otherwise) open and able to reference during the procedure.

The FMS, btw, is not why a B747 can execute a cat III landing. The aspects to that include crew certification (have to do a bunch of stuff in a sim to get certified), crew training (special procedures between the pilot flying and pilot not flying to setup the avionics, monitor the avionics and make the land/go around call), aircraft certification (there are extra sensors and instruments on the airplane with painted critical areas around them that must be free of dents and irregularities on preflight; the flight computers do more sensitive inter-comparisons between all of the instruments, the localizer is tracked with more sensitivity, radar altitude is used rather than pressure altitude), and airport certification (specific lighting systems must be installed and used, and the localizer and glideslope must be usable to the surface).

There is a lot more that goes into being able to fly and actually flying a cat III (my plane could only do cat II, but the concepts are the same) than just programming an approach into the FMS and engaging the autopilot.
