  • Commented on From Here To The Holodeck
    Motion sickness in VR is usually caused by poor tracking and latency. The view is supposed to follow your head position, but the sensors that track the movement are imperfect and it takes a finite amount of time to generate...
  • Commented on From Here To The Holodeck
    Lightfield displays suffer from the same problems as lightfield cameras unfortunately - you need a large number of pixels between each microlens to get a fairly low resolution output. OTOH I think that desktop hardware is probably capable of doing...
  • Commented on From Here To The Holodeck
    Coincidentally I came across this article yesterday https://www.gamasutra.com/blogs/EikeLangbehn/20171106/309037/Perception_The_most_technical_issue_of_VR.php The relative ease of reproducing things like the "rubber hand illusion" in a virtual environment should have obvious implications for horror game designers. If I'm reading it correctly all you need is...

    Reminds me of an old E.E Smith story with a hero who, when stranded on one of Jupiters moons* uses heavy engineering magitech to build a thermocouple power station between the equator and the poles. *habitable of course....

    Only if you are rational. "us vs them" has never been about rationality....

    By the time PERL 5 came out it was too late for me. I had seen PERL 4 and was disinclined to give it a second chance....
  • Commented on Crib Notes: Empire Games
    I would say that the only good decision I made in the 1990s was refusing to learn perl, purely on the basis of aesthetics. One of the few cases where I have never regretted my ignorance....

    Given the following: 1. We know how to make smallpox vaccine. 2. We don't have very much of it. 3. Virtually nobody under 60 has any immunity. How long would it take to ramp up production and contain an outbreak...

    Non pointery references have been around for ages before the likes of perl, where in this case "pointery" means you get to do pointer arithmetic. Tony Hoare apologised for inventing null, but I strongly suspect that if he had avoided...

    As an aside, I was able to use my 68k* based personal computer to do useful physics calculations well into the 90s. Wouldn't be seen dead with less than 16gb RAM and 512 CUDA cores these days but the difference...

    Of course that opens you up to the important questions. Amiga or ST? :)...

    There is a certain type of person who thinks it is cool to make every little thing turing complete. I used to be one of them, but long ago came to my senses and concluded that they are insane. The...

    I mean the socket, not the lighter itseld. I don't use them to set fire to things, do use them to power equipment....
  • Commented on Crib Notes: Empire Games
    Car cigarette lighters aren't all bad - high current sometimes counts for a lot. I sometimes use mine to run an inverter that then powers things that would not react well to being run on a USB connector. I need...

    The trick is to get as much of the countries wealth into your swiss bank account as possible and jump before the revolution. Guess who used to play too much "dictator" :)...
  • Commented on Crib Notes: Empire Games
    You don't have to be particularly ambitious to take that sort of thing into account. I recently turned down a very interesting looking job largely because the tech they used would lead to CV rot and leave me unemployable* within...

    Doesn't it show that the correct place to be is at the top? :)...

    Ridiculous idea of the day. Cheap hypersonic international travel using black hole gravity assists. You just need an aircraft with a completely sealed, vacuum ready cabin and very good timing....
  • Commented on Crib Notes: Empire Games
    Trusting trust attacks can be mostly avoided by simply not implementing compilers in the language they compile. e.g. running your C compiler on a LISP interpreter that in turn runs on a minimal FORTH like coded in a few hundred...

    SISAL! The number crunching language of champions! :) OK, it was a very promising experiment that got killed by the FORTRAN lobby. Nobody really knows how it would have panned out if it had more money thrown at it, but...
  • Commented on Crib Notes: Empire Games
    In addition, there is a big difference between developing tech for the first time and knowing where you are going. A huge number of the inventions of the 19th and early 20th century were dead ends, huge amounts of effort...

    Didn't think so. My house is afflicted with dimmer switches left there by the previous denizens. Have dimmable LEDs in most of the fittings now, but thinking it is time to just change the switches as they are always on...
  • Commented on Crib Notes: Empire Games
    That's the one. If I ask if they are dimmable will I get laughed at? :)...
  • Commented on Crib Notes: Empire Games
    I seem to remember an image of the sort of LED lamp that would probably need welding glasses to approach. I was tempted to get one but didn't want to blind the neighbours....
  • Commented on Empire Games gets a price cut in the UK
    Going back to this old subject. Stand down, the world isn't going to end. Looks as though whoever did the press release got confused about which symmetry they were testing. http://www.math.columbia.edu/~woit/wordpress/?p=9700...

    I think there has been some progress on the theoretical side, but it's such a weak force that experiments are hard even in principle. I suspect we will be waiting a long time for a satisfactory answer. @jbs I guess...

    "The universe shouldn't exist" here is code for "our model appears to be wrong". When the universe fails to fit the theory, blame the universe....

    Received Pronunciation was a major issue in the UK too. There is stil a noticeable bias but for decades anyone who wanted to be on tv or radio had to pretend they didn't have an accent*. *the right accent =...

    These days if you really want someone then put them in a position where they have to either lie or admit to something embarassing, then prosecute them for lying. So long as they don't know that the choice between divorce...

    Well firstly that scenario assumed that for whatever reason you hadn't even looked at the battery health indicator *and* the battery was about to die. Even so, you're still 6000 pounds better off buying the electric than being given a...
