  1. Re:Flight controls instead? on California DMV Told Google Cars Still Need Steering Wheels · · Score: 2

    Chrysler experimented with a stick-approach in the sixties, it really didn't work very well. The steering wheel that is capable of multiple revolutions allows for fine-grain control over steering, same goes for long-pedal-travel analog brakes and throttle position.

    Think back to playing with cheap radio-controlled cars, it was difficult to navigate tight courses because the cars couldn't steer accurately enough, and if they were really cheaply made and open-wheel types, breaking a control arm at a front wheel was a real possibility.

    As Toyota demonstrated to us, that manual break needs to be damn-near hardware-level too, or at least allow for an emergency override that interrupts the computer entirely if the main 'stop the car now' brake fails to work properly.

    It would be terrifying to be in a self-driving runaway car without any controls whatsoever.

    It's going to depend on who's allowed to use a self-driving car and under what conditions, and even so far as what seats are allowed to be occuppied.

    I can see a tiered system where licensed drivers with a normal operator's permit are allowed to always occupy the driver's seat in a vehicle with the capability of full control. I could see a special provision of license for those who once held normal operators' permits that voluntarily gave up those licenses (elderly, poor vision, etc) so that they could basically pull-over the vehicle in a crisis. There could also be a special class of license for learners' permit operator licenses that allow the person to occupy that seat. Everyone else will be required to occupy any-other-seat unless all seats are occupied, then there would have to be conditions to allow that seat to be occupied while the controls are disabled.

    Paging protocols were never that efficient though. I did work at a company that had been a paging service company previously and had migrated into the software side, and apparently it was possible to set up the network to send-out pages several times since there was no feedback that a page was received, and pages weren't always queued up and sent as quickly as one would normally like, at least not quickly enough to allow for near-real-time use like you describe.

    I do like the idea though, it would save bandwidth and battery life most likely.

    I just assumed that if you can communicate bidirectionally that they roughly know where you are.

    Isn't that partially why receive-only paging services still exist, because those that don't want their location tracked still want to be able to receive notices?

    Probably more accurate to say that there are two distinct game industries and two distinct markets. One concentrates fairly specifically on puzzle-type games, with a seeming emphasis on tetris-like or connect-four-like games with most development being done for portable devices, while the other concentrates on time-dependent action games, with some longer, multiturn strategy and other types of games too, played on more stationary, immersive platforms.

    Personally, calling the players of the former "gamers" is like calling card players or board game players "gamers". To me, "gamer" as a title implies more of a subculture where one plays games to the exclusion of many other activities, rather than someone that plays casually when they have time to kill. At one point I definitely was a gamer, but now I have other ways to spend my time, and loading the occasional first-person car racing game or shoot-em-up doesn't make me a gamer.

    I've known women gamers, who played games to the exclusion of other hobbies, that owned video game consoles and action games like Splatterhouse, Contra, and Sonic, and the current trend does not follow that paradigm.

  9. Re:Stupid metric system on 2 Galileo Satellites Launched To Wrong Orbit · · Score: 1

    It's unfortunate that SI was based on the old French meter, it's just too big in general use, something smaller close to a foot would have been better then we wouldn't have ended up with a worthless deci/deca meter. Centigrade is the same, in looking for a cleaner measurement they used boiling water as the high end which made the unit too large for common use but great for scientific measurements.

    And that in a nutshell is my beef with SI. The idea for unifying the units for conversion/comparison of natural properties is wonderful, but the initial starting point is flawed.

  10. Re:Stupid metric system on 2 Galileo Satellites Launched To Wrong Orbit · · Score: 1

    Do not generalize. An airplane's wing is many meters long, yet its tolerances are in the mm range or smaller. Some application do benefit from being able to freely mix prefixed units. Since having two incompatible systems is stupid, it makes sense to standardize around the better system.

    An aircraft's wing is in meters, not in Kilometers. It's expansion and contraction due to temperature and aerodynamic stresses causes it to change length more than a centimeter during operation.

    Besides, SI has no monopoly on precision. I had an engine bored to 0.0020" over the 4.030" diameter of the pistons, and the bearings are .00010" clearance from the journals on the crank. And going back to aircraft, the Boeing 787 was designed and is built without SI units.

    Angle.

    For the record, I'm perfectly fine with SI being the principal units system for scientific research, in the sense that once one leaves day-to-day use it doesn't matter terribly much. On the other hand, SI has proven, in scientific terms, to itself be flawed. Attempts to redefine the base units using natural constants aren't finished either. That means now all you have is an easy conversion system.

    Yeah, I know. Off by one size. Either way though, there's no good way as far as I can tell to know what metric sizes can be skipped. Without knowing that I either have to have a shit-ton of sizes with many that inevitably won't see a lot of use, or I'll find situations where I'm running to the store for the one wrench that I need because it wasn't included in the set.

  14. Re:Stupid metric system on 2 Galileo Satellites Launched To Wrong Orbit · · Score: 1

    I don't really ever need to know how many inches are in a mile. Things measured in miles do not need the precision of inches. They don't usually even need the precision of feet. Things measured in kilometers do not need the precision of millimeters, or centimeters, or decimeters, or usually even meters the vast majority of the time.

    The boiling and freezing point of water doesn't do anything for me in my day-to-day life. The scant number of times per year that I need to boil water it's a matter of putting a pot or pan on the cooktop and turning the heat on and waiting for it to boil, then not being stupid about putting too much cold stuff in at the same time to drop below boiling. What I need to know is how the air temperature will affect me.

    And since you insist that I don't need tools at every mm value, please enlighten us, what sizes can I skip and never meet a fastener that I cannot correctly turn? What rule is there to know this? Because right now I have everything from 4.5mm through 28mm with the addition of 5.5mm, those tools take up a lot more room for that span covered than my 5/32" through 1-1/8" even with four tools at 1/32" increments in addition to the 1/16" increments of the rest. For SAE, above 11/32" it doesn't make sense to continue using 1/32" fractions so they stop. Above about 1-5/16" it stops making sense to use 1/16", so they stop.

    My theory is that most pre-Metric units were designed because they're sizing/spacing was convenient to the type of measuring and the task at hand.

    I work on a lot of machinery. To cover a span of 1" or 24mm, I need almost half-again as many mm-sized tools as I need SAE-sized tools at 1/16" increments, and I can't omit any metric sizes because there's no rule that I've found on where one can go from x1mm to x2mm or x3mm spacing between fasteners. With SAE tools, once above 1-3/8, typically one only needs to carry 1/8" increments, and above 2", 1/4" increments.

    0 degrees Fahrenheit is really cold, about the coldest that one can stand by simply bundling up, without having to resort to special clothing. 100 degrees Fahrenheit is pretty hot, about the hottest that one can stand without having to take special precautions with hydration and attire. By contrast, -18 degrees Celsius and 37 degrees Celsius aren't terribly intuitive.

    SI also lacks a good equivalent to the Foot. Decimeters are only about 4" long, and meters are over 3' long, so nothing in between.

    SI reminds me of hyperinflated currencies, where the units don't align well with real-world uses. I like the idea of base-ten conversion given our current numbering system, but the scales are off.
