    Psychologists and patients can get by with VR simulations using a VR glasses and a powerful gaming PC. They just ctrate a game map that resembles the experience that gave the patient PTSD and gradually increase the realism. They can also create regular street scenes with car engines backfiring, motorists yelling, construction workers running machinery and dropping crates. Gradually they desensitize the patients to these stimuli.

    When most people do addition, multiplication, subtraction or division, they do it in the way you woulf get a computer program to do it using ASCII strings.

    An ioiot savant is either doing the calculation using lookup tables or a optimized and parallelized algorithm.
    Like when you memorize the times table, that is basically associative memory.

    A lot of projects are cross collaborations between academic researchers , DoD, and corporations. Researchers need access to download/upload data, results, source code and documentation as well as use facilities like wind tunnels, supercomputers and wave machine water tanks.

  8. Re:Looks like the SCADA variant on Researchers Seek Help In Solving DuQu Mystery Language · · Score: 1

    Lots of libraries are event-driven: X-windows, GUI widgets, Qt, device-drivers. Even certain 2D graphics API's had callbacks like TIGA.

    Back in the 1980's, ADT (Abstract Data Types) were the big thing in C programming. They were the predecessors to object-orientated design. You started by having a typedef'ed structure. Then you had init, allocate, deallocate functions. With function-pointers (something like: int (*procfunc)( int param1, int param2) stored within that structure, you could do all sorts of C++ things, like different instances of different class types. While C++ inline functions didn't exist, you just used macros to modify structure variables.

    Function calls were also expensive (thus the use of macros). Compilers like Borland C++ (the command line version) had all sorts of compiler optimizations to speed up function calls (it also did as much work to implement UNIX library functions as possible). There were different ways of optimizing function calls. One way was to avoid saving the entire register set - though that would mess up interrupt handlers. Another way was to use register variables for function calls as much as possible. There was a different between Pascal and C function call conventions. One had the calling function clean up the stack frame, while the other version had the called function do the clean up. Then there were all the different programming model sizes (tiny, medium, small, large, huge). These had different code, data and stack segments (64K = 32-bit). Other optimizations were for size or speed. There was the capability to generate DLL files. Other optimizations would include merging small functions into larger ones.

    Interesting thing was, that the Borland C++ compiler would pick up just statements outside the case conditions of a switch statement while GNU C++ even today won't. Even a return followed by a break would cause an unreachable code error.

    Or a magnetic field as well - which decreases in strength by 1/d^6 - not squared, cubed, double-squared, but just raised to the power of six, which suggests that what would seem to be empty or solid space at our dimension, would be like swiss-cheese at sub-atomic scales.

    I'd imagine both cases are a form of induction - you create a field in one point, and adjacent points realign or stretch to balance out the differences in gravitational or magnetic potential and alignment. There are infinite ways of trying to produce a visual way of representing what is going on - superstrings, vortices, sinks and sources. It's just a matter of finding the right experiment.

    They did similar experiments with brain electrode vision. They placed a mesh of electrodes over the visual field of the brain and then gradually matched electrodes to locations in the visual field. Had to carefully balance the voltage levels as there was the risk of migraine, epilectic fit and dizziness. Main problem was that before the system was powered up, the brain had set all inputs to maximum gain in order to get visual input. Of course, there wasn't any. So when the electrodes were activated, there was a shock pulse while they renormalized.

  17. They have done research with electrodes wired into the brain. Paralyzed patients were able to control a cursor in four directions and select items. Unfortunately, having a hole drilled in your skull with a RJ45 socket wasn't the most practical interconnect. Maybe a Bluetooth dongle would be more practical, but there is still the problem of keeping the client side powered up.

    In the past, your friends would draw you a simplified map of the neighboring streets using a device known as a pen on permanent non-volatile memory surface known as paper. The really neat thing was that as long you kept it dry, the information would be retained permanently. If you were really lucky, they might photocopy part of a map and place a photograph of their house. These too were really neat in that they stored street numbers, so you knew what end to travel too.

    Sometime they might even leave the front porch light on, place balloons outside the entrance, or place candles along the driveway like landing lights, so you knew you were heading in the right direction.

    You cannot use the the old legacy 173.xx.xx Nvidia drivers in F16. It is not compatible with the current version Xorg.

    What would happen is that some bit of the kernel grabbed up the PCI interrupt/memory map and allocated it to the nouveau driver. The NVidia driver installer would complain about not finding some interrupt or other. If the nouveau driver wasn't there in .ko form, X-windows wouldn't start.

    I couldn't even use the package installer to remove the nouveau driver without it wanting to take out the entire X-windows/Xorg system. The Grub boot system had also changed rather substantially. Even using "dracut" wouldn't help.

    The secondary problem is that there is a housing shortage within the immediate commute area. Employers and cities then have the challenge of shoehorning hundreds of thousand of people into a few dozen square miles. Somewhere like Silicon Valley is one example. First you have the salary differential between CEO's, directors, senior engineers and graduates. Everyone wants to live in a house close to work. Most people from senior engineers upwards are looking for a large home with bedrooms for themselves and their children. The entry-level graduates are then forced to share rooms. If you boost salaries, then rents, house prices and mortgages rise to compensate until you are back where you started. The only real solution is to improve transport systems so that commute times aren't as long for new builds. Or relocate offices.
