    The OP was talking about another petroleum cycle to produce fuel for another round of intelligent organism to use. Hopefully your retirement plans are finalized before that several hundred million year process has completed.

    One would expect any commenter on slashdot to have at least the most basic grasp of physics necessary to realize that a solar powered aircraft will never have any utility beyond low speed loiter, and will never replace all those terrible contrail-producing jets. One might think too highly of the common slashdotter...

    So they made it work. Who cares? No one with a firm grasp of aerodynamics and engineering said it couldn't be done. They only said there was no point for it to be done. It's like the person who climbs Mount Everest without oxygen. They're going where many have gone before, but crippling themselves for the XP bonus. It is of no benefit to society, so there's no reason society should give it so much publicity.

    Doing as the OP suggests would, almost certainly, "cause reasonable fear of material harm to the physical health, safety or property of such person, a family member, or an acquaintance"

    Such a threat is implicit in the actions advocated by OP.

    That's the definition of "assault", but I suppose I should have expected severe overlap so they can charge you with half a dozen crimes at once...

    That's not stalking. Stalking requires you actually... stalk someone. Just saying that you know where he and his family operate could at best be considered assault.

  14. Re:Bleh on Ford's Bringing Adaptive Steering To the Masses · · Score: 1

    The steering itself is not adaptive. Only the feel from the steering wheel is adaptive. You will have less power assist at higher speeds. Manufacturers have been doing this with hydraulic power steering for a long time.

    Not even proper joysticks, but shitty mini-analogs.

    All you need to do to discover how bad an idea joystick controls on a car would be is to try to use a scissor lift. They have a lot of torque (at low top speed), and you basically have to wedge your arm into the control harness and control the stick with a stiff wrist. Otherwise, you push the stick forward, the lift accelerates, inertia jerks your arm back, and you pull back on the stick. Rinse, repeat...

    The ACK is crucial. Even if you pipeline your packets so you do not have to wait for each ACK to return, they are still vital to measuring network capacity. Too many people trying to send too much data will eventually overwhelm the transmit buffer at some congestion point, and loss will shoot past the ability of your error correction to compensate for.

    Any well designed data center was already able to rapidly provision new capacity and relocate processes around damaged hardware. It's the logical evolution of the batching systems used by the HPC sector since the beginning of digital computing. Calling it "the cloud" is just a way to drum up business for outsourced hosting services by making it seem like they're offering something magical.

    If it's private, it's not a "cloud". It's just a bunch of HA and automated provisioning baked into the data center management software.

    All "clouds" must be over the internet. The whole point of "the cloud" is that it is located remotely, on someone else's hardware, managed by someone else's IT staff. Elsewise, it's nothing more than the same data center you had a decade ago.

  23. Re:Bowler on Servo Stock 3D Printer Brings Closed-Loop Control To Reprap · · Score: 1

    Bowler is just the packet protocol, independent of physical wiring or wire protocol. That still has nothing to do with the primary issue of why they chose to write their own protocol, rather than choose an existing one that sufficiently approximated their needs. As a garage tinkerer, surely you would want to use hardware that operated on an industry standard interface, so you could choose from a vast selection of existing hardware. As an educator, surely you would want to use hardware that operated on an industry standard interface, so those you were teaching would be familiar with a technology they could use in the work place.

    The only reason for them to write their own protocol is because of ignorance, hubris, or the desire to produce their own hardware ecosystem they can exert control over.

    Plus you can add an additive that causes "knocking" i.e. easy self ignition, in diesel engines, instead of antiknocking agents in Otto sparkplug ignition engines, and then as every droplet contains that knocking agent that easily ignites, the whole spray droplet should easily ignite.

    Then you're not running the same fuel out of the pump as gasoline engines, or you need to include a large quantity of a secondary fluid. It defeats the whole purpose of a multi-fuel engine.

    This might mean a super diesel of unheard of compression ratios/temperatures

    As you've stated, diesel engines don't start pumping in fuel until after the compression cycle, so knock is not a limitation, and the only limit to compression ratio is materials and mechanics. Just being able to use a different fuel isn't going to remove these limitations, so using a different fuel won't mean any significant change in compression ratio or temperature.
