    They could patent the components used, the type of digital data sent back, the software clean-up required, the fabrics used. Like a system of fibre-optic cables, light sensors, ADC converters with a wi-fi/bluetooth interface.

    It's like being at driving school again. Learn to start the engine, ensure the engine is in neutral, put the car into 1st gear, accelerate, brake, learn to turn left and right, reverse driving, reverse turning, going up and down hills (lower and higher gears). Then you try various obstacles, more complicated road layouts like hidden junctions, roundabouts, exits hidden behind hedges and trees, traffic lights on steep hills, hairpin junctions that require sharp turns. Various hazards like school zones, one way roads, farm vehicles and animals, riding schools, wild animals in forests.

    A "vast peer-to-peer network" sounds like cloud computing. Cisco once tried to get their users to configure their Linksys routers through "The Cloud". Unless told to do otherwise, routers would auto-update the firmware so that all configuration settings could only be controlled from Cisco's router management website.

    All the game developers who have already published titles have a massive code base of shaders and rendering code that they need to maintain. They can only justify upgrading all that code to do something better if they can provide it will boost short-term revenue. Because they may have written their own abstraction layers to encapsulate multiple platforms, they simply can't just change one shader at a time. They'll have their own standard for defining materials, particles, skinned characters, cameras and model positions/instancing. It's easy to take advantage of new shader features to write a new shader, but to rewrite everything from scratch just to use compute and geometry shaders. In some cases, may new shader functionality rapidly becomes outdated with something new (transform feedback vs. compute shaders, uniform buffer objects vs. shader storage).

  8. There are some variations. Traditional French buildings tend to have high rectangular windows with frames that open vertically so you can let all the fresh air in. They also have frames for flower boxes at the bottom. Another European feature is to have shutters that can be open against the wall or closed over the window. Modern versions have shutters that roll down over the windows and doors (French legislation for any property that is uninhabited).

  9. A GPU consists of anything from four to thousands of processing cores. Each core in turn will have multiple logic units to handle integer operations, floating-point and vector instructions (linear algebra like dot and cross products), so that it can perform multiple instructions at the same time along with instruction pipelining. Add several layers of cache to minimize the amount of data read and written to main memory, and you get something like the Titan Z which can do 8 TeraFlops.
    The clock speed of the graphics board and data bus size dictates the number of pixel writes that can be done in one second, currently billions of pixels.

    Rendering is done through shaders, which are mathematical programs to do vertex transformation, perspective projection, parametric surfaces, subdivision, vertex removal, silhouette generation, doing shadowing tests, calculate ambient, diffuse, specular lighting, and many other advanced lighting models, texture mapping, and all sorts of other mathematics.

    I worked with very early internet technology in the 1990's. Back then, the network chip was on a separate board just like the graphics card. The MAC address had to uploaded into flash memory on startup. These could blow up given the right conditions, then the card would either just keep blasting out random packet data, or traffic collisions would result in fragment packets (less that the minimum size) going out. Some early day drivers would pick up these packets. Filtering was done in software. Now with these chips built onto the motherboard, the hardware does all the filtering.

    The way the market is set up is that when there is an increase in demand, the cheapest energy producers go online first, then it goes all the way up the cost scale to the most expensive ones last. The order is something like hydroelectric, coal, gas, solar, wind, nuclear. But the market price is set by the most expensive producer at the time of demand.

    Back in the mid 1990's, I went out to buy a new TV (Sharp 24" flat-screen CRT). They were advertised as "cable-ready". They had a built in decoder that could access free-to-air cable channels. just plug in the connector from the cable network and no need for a decoder box. When I paid for a basic subscription, the cable company were completely confused as to why I was able to get service without a cable box. They had to send an engineer round to check it out.

    Today, we now have internet-ready TV sets that can plug into internet broadband and play any movie from NetFlix, YouTube, and any other video hosting site. It's completely bizarre how you can watch many news channels free-to-air (FreeSat in the UK) through satellite dish service but have to pay for a subscription to cable to watch the same channels. Now the satellite company (Sky) is muscling in one cable service.

    https://en.wikipedia.org/wiki/...

    Supercapacitors are used in applications requiring many rapid charge/discharge cycles rather than long term compact energy storage: within cars, buses, trains, cranes and elevators, where they are used for regenerative braking, short-term energy storage or burst-mode power delivery. Smaller units are used as memory backup for static random-access memory (SRAM).

    If you start designed computers as self-contained modular blocks, you would want the CPU and memory together with some battery power - that's where the supercapacitors come in. You might want a digital camera with flash memory.

    Sometimes the internal CPU data bus can be 128-bits, 256-bits, or 512-bits, but the external data bus on the board is 64-bits. There isn't anything to stop the two being different sizes except the bus protocols for sending and receiving data. This applies to the address bus as well. Some 8-bit systems got around the memory limitations of 64K by having a hardware page register that could select a particular bank of memory visible through a virtual "window". PC's from 1990's used segmented memory where everything was accessed in 64K segments.

    Different GPU's would have different levels of efficiency for various tasks. This would depend on cache sizes, float-point precision, number of parallelized logic units, queueing, cross-bar switching, and all sorts of other parallel processing tweaks. Data flow design isn't any different from getting as many customers through a Disney theme park as fast as possible.

    Whichever GPU is faster is going to do most of the work.

    They'll do research and try and raise clock speeds, but the amount of heat required and the amount of cooling required is proportional to the square of the clock speed. The faster you try and change the state of something (electric charge), the more heat is generated. They might be able to switch to optical computing then the heat problem goes away. Maybe they'll get more efficient CPU's with fewer transistors and more parallelization.

    But, it's far simpler to just add more cores as transistor sizes shrink by a half every year or two. That's guaranteed.
