    "Do you care about transistor density?", will get a lot of "Huh?", which will be interpreted as "no, does not care".

    "Transistor density is one of the biggest factors in computer speed. Do you care about making transistors more dense in the future to improve computer speed?" will get a lot of "Yes", because people want the computer speed, even if they don't understand transistor density.

    Polling has gotten a bad name because the loaded questions spew the results, and make headlines.

    If I recall correctly, one was using bank-switching, so that while you had a 640K address range (alright, it was a full 1M, but parts of it were reserved for other memory mapped things because IBM knows how to design for the future), the memory space you reached changed as you adjusted what pages mapped where. This one worked on 286's that could not actually use a 32 bit memory space. I don't recall if it worked on plain 8086's or not.

    The other just gave you a straight 32 bit memory range, but required that your users update to a 386 processor.

    that crap sucked back then, and neither nostalgia nor hindsight make it suck any less.

    If your processor *cannot* access more than 1M of address space no matter what, than you have to come up with some way to do this.

    Bank switching is *old* technology. Heck, my Atari 2600 had an add-on expansion that gave it (again, from memory) two switchable 2K banks of memory, so that your 4K addressing range could access a total of 8K of ram, plus routines to load the next section of your game from cassette tape. Surprisingly, the same chips that Atari used in the 2600 gave much better graphics when you upgraded the ram from about 128 bytes to 4K -- over-designed chips.

    That california high-speed rail? It's cost?

    Disney was willing to build, at it's own expense, a high-speed rail line from the southern tip of BART, to San Diego. A stop at the peopletrap, of course. I think they planned 5 other stops as well.

    All they asked from the state was right-of-ways. It would have been a high speed rail line for transferring large chunks of population, large chunks of people over the primary travel locations. And fast.

    The state's response? They wanted lots of stops. Not just a small handful.

    ** High Speed ** does not exist when you have lots of stops. Period.

    If you want a high speed rail as a backbone of a state-wide travel system for something like California, then you have to have some sort of feeder and backbone system. Disney was willing to build the backbone and pay for it entirely. California didn't want to make the feeder, told them "Do it all, or don't do it". So Disney didn't do it.

  13. 5700 years ago, this simulation was started on Neil deGrasse Tyson Says It's 'Very Likely' The Universe Is A Simulation (extremetech.com) · · Score: 1

    Approximately 5700 years ago, God started a simulation of the universe. Why?

    We can only guess. Perhaps someone asked a question, that was so complex that the only way to determine the answer was to simulate the universe, and determine the answer. Given the huge cost and difficulty that this has resulted in, God has now decided that "Seer of Mind" is just too expensive of an ability, and there will be no more "blind justice seekers" into the future. But the existing "justice is blind" seekers have demonstrated just how crazy the view is.

    When the answer is determined, the Seer of mind will know the result of the choice, and will then know whether or not to kill her opponent. Later, someone will retcon the choice and the whole "put down your arms and don't fight" will turn out to be the better choice. Hence the whole "be kind to each other" that is preached and ignored in this simulation -- the truth tries to show itself.

    Which is patently false. I decree that the set of universes which are simulations in the sense of Tyson have measure zero. Therefore, it is a zero probability that the current universe is a simulation.

    Seriously? ** You are not allowed to assume your conclusion! **.

    ---

    Basic premise, summed up: Given the assumption that 1) future people are likely to want to run simulations of the past, 2) the computer power to run simulations of the past will exist, then the conclusion that someone will run such a simulation is extremely highly likely.

    Now, add the assumption that the ability to run such simulations will be widespread at some point in the future, and the probability that we are a simulation changes from "Maybe" to "Likely".

    These are *not* easy assumptions. Moore's law cannot continue to infinity. The energy needed to run an arbitrary complex computation/simulation is arbitrarily high. It may turn out that the energy cost is measured in stars / aka dyson spheres to power the computational complexity.

    ---

    When we look at our universe, we see things that seem to be signs of simulations. Given that, there questions are:

    1. Who is running the simulation: Our descendants inside this universe, or some being that exists outside this universe? (NB: Some people call such a being "God".)
    2. Is this in fact accurate observations on our part, or is this something that we just aren't looking close enough / well enough at yet?
    3. Is physics just weirder than can be possibly understood? (i.e. not actually a simulation).

    Question #3 there is actually asking if science is inherently pointless -- if assuming that you can learn by observing, and that the arrow of time does give some sense of A causing B, etc., -- all the basic assumptions of science -- are in fact bad assumptions.

    I mean, imagine if the assumptions of science were to yield the result that causality is in fact a lie -- that A never actually causes B, but only ever has a correlation effect that while close to 1 is always measurably less than one.

    I mean, that can't be scientific truth, can it? :-)

  17. Price per game; lack of trust on Slashdot Asks: Is the Golden Era of Video-Game Console Sales Over? · · Score: 1

    I'd say that the decline in video games comes to a few key points:

    1. Lack of trust / ownership. We're at the point where the makers of the consoles basically say "You don't own it, we can change the terms of usage, you can be locked out of your own device, you can't do any soft modding, and if you try we can wipe your softmod or wreck your device because our TOS says we own it after you pay for it".

    See Nintendo and the Wii U.
    Now realize any of them can do this.

    2. Price per game. Lack of any significant discounts.

    3. We're not that far from tying your purchased games to a single console, completely eliminating any resale market -- point numbers 1 and 2 to the extreme.

    4. As others have mentioned, a normal computer is becoming more convenient than the consoles.

    5. The fundamental question: Why bother?

    The Wii gave us a reason to bother: the motion-sensing control. And then the improved control that actually senses motion instead of sensing jerks and angles. Now if only the software was actually fixed/improved -- many of the games seemed to operate under "Ok, we're learning how to work with the controls, and got X working, we learn more, make Y much better, we now know how to go back and improve X, but we won't". And this is *before* shipping.

    Nintendo's own "Wii Fit" is the perfect example of this. I'm sorry -- the quality of working with the balance board is different in the different exercises, and worst, when they made Wii Fit Plus, they did not go back and fix any problems with the older exercises/games.

    The Wii Sports Plus, the key game for the Motion plus sensor? Seemed to have the exact same issue.

    6. Reduced quality / lack of bug fixes and patches. Yes, computer games get patches and fixes. Can you add a patching system for these cartridge/CD games? Sure. Do they? Nope.

    1. Install a second copy of the OS (repartition the drive to include a second partition).

    Said file is protected, but you *can* boot in the recovery boot, empty that file (or other specify that the entire disk is not protected), and then you have full control (And exposed risk) as root.
