  1. BART and AMTRAK strike again. on The Quest for the Car of the Future · · Score: 2, Interesting

    Motors in the wheels? ... How they hell is this a new idea?

    It's an ancient idea in internet time. They were talking about this back in the 1950s.

    It's also a rotten idea. The more mass in each wheel, the more forward momentum is converted to vertical momentum in the suspension as the wheel follows irregularities in the road, then converted to heat as the suspension damps the bounce. This is one of the major sources of energy loss that must be made up by prime-mover power.

    I.e.: Heavier wheels, lower mileage. That's why even electric cars with independent motors on each wheel put the motors on the frame and connect them with axles and CV joints, despite the considerable increase in moving parts count and expense.

    NASA designing a car? Why does this remind me of BART and AMTRAK? In both cases aeronautical engineers were hired to redesign a surface vehicle (despite their experience with surface travel being limited to things like landing gear, used for a tiny percentage of each flight). In both cases they threw out more than a century of engineering solutions and started from scratch. And in both cases they ended up with an expensive deisgn that had rotten ride. (In BART's case new cars now cost six MILLION each and even at that price only one manufacturer - located in France - is willing to build them.)

    You need acres of solar cells to power a commuter car - even an extremely efficient one. Putting some on the car itself can actually be counter-productive, unless you only plan to use it once every few months or so. You may have to burn more power to tote them around than they produce.

  7. How I wish that were true in California on NC Man Fined For Using Vegetable Oil As Fuel · · Score: 1

    Taxes are very seldom taken "for nothing", they are usually recycled into services for those who paid the taxes.

    Unfortunately, once the government gets its hands on money, it generally loots it for other purposes than the one used to justify collecting it.

    California's fuel taxes and tolls are particularly bad examples: Both the bridge funds and the fuel taxes have been looted to support politically-correct "transportation related" projects such as public mass transit systems (which, in northern CA, are so poorly organized that they're nearly useless).

    In the case of the Bay Bridge this was so extreme that when it came time to do an earthquake retrofit there was nothing to do it with. So they raised the tolls on ALL the bridges in the area (most too far away for the traffic to be related) - by a factor of several - mainly to pay for the Bay Bridge work.

    Caltrans in the SF bay area also deliberately takes a long time on road projects and otherwise impedes automobile traffic (and drastically lower its fuel efficiency as a side-effect) in an attempt to force drivers onto the impractically-designed public transit systems and "get them over their love affair with the automobile". (They admitted this when LA had repaired its own freeways after a major earthquake in a few months, while SF was still working on the Loma Prieta quake damage after years.)

    This all got so bad that a ballot measure was written to try to earmark the gas taxes and tolls for road work a few years back. But it was poorly written and would have let much of the practices continue (and also got caught in some other state politics that distorted the turnout). It was narrowly defeated at the polls.

  11. Chicago in '68 and Rodney King. on Digital Camera Memory Card With Wi-Fi · · Score: 1

    French cops have a new tactic in protests : when they label someone "troublemaker" they ask him to delete his camera's memory. Wifi could be a way to get around that.

    News coverage of the "police riot" in Chicago in 1968 swung a presidential election and its fallout causes a sea-change in US politics that affects things to this day.

    This was the result of a technological change: Chicago police were used to suppressing news of their activities by smashing the newsies' cameras. That convention was the first major deployment of the early "minicam" - a massive, just-barely-man-portable, over-the-shoulder TV camera with a backpack full of support electronics capable of relaying the image to a truck within a couple blocks, which could then relay it to the local studio.

    Result: Not only did smashing the camera do no "good", the image of the oncoming billyclub might be on TV screens across the nation before it actually hit.

    The Rodney King debacle was a similar quantum leap: This time it was due to the availability of videotaping cameras inexpensive enough to be common even in the inner city. Now police behavior could be videotaped by ordinary citizens and passed on to the press. California's response to the issue was to make it illegal for citizens to tape them "in the performance of their duties" - letting them seize the cameras and tapes in future incidents.

    This product potentially gives individual "watchdogs" the same capability that the TV networks got in 1968: The ability to take a picture and have it safely out of the camera - into a laptop around the corner, relayed onto the net, or whatever - before the instrument can be confiscated.

    Its time to encrypt EVERYTHING. ( at least until the government bans it )
    Sure they know where you went, but not what you viewed or 'said' while there.


    Back when I was operating a mailing list on a controversial topic on my home machine, I had a couple rules:
      - No postings soliciting or admitting to breaking laws.
      - No encrypted traffic (not just on the list: All traffic (except passwords) to-from the machine was in the clear).

    The thinking was like this:

      - Police, other government investigative agencies, and various unofficial snoops have a long track record of ignoring laws against various kinds of eavesdropping. So you have to assume that the line might be tapped.

      - If the police became interested they could always get a warrant and tap the line. (Or illegally tap the line without a warrant to see what's going on, then (if it looked interesting) get a warrant to tap it legally.)

      - If the data was encrypted they could STILL get it - by getting a warrant and seizing the computer (and everything else of interest in the house).

      - If the data was UNencrypted they would want to keep a low profile to avoid scaring off any "bad guys", would eventually see that there was nothing to go after, and thus would probably switch to hunting real bad guys elsewhere and go away WITHOUT breaking in and trashing stuff.

    "Encrypt everything" seems like a nice solution. But if only a few are doing it, just the fact that their traffic is encrypted makes them targets. It's easy to trump up enough stuff to get a warrant and go after the machine.

    Once a LOT of people are all swapping lots of encrypted traffic (as the default way of "sealing" the "envelope" on the datagrams) the fact of encryption will stop making the users targets. (The police can still get a warrant and grab the machines. But with so many potential machines to grab they'll have to find some other way to pick the ones to hit - like by bothering to dig up real "probable cause" from other evidence, like they're supposed to.)

    Fortunately we don't need to construct a "shelling point" for this: The internet is gradually moving toward pervasive encryption, as the legitimate need to encrypt for personal and corporate security becomes broadly understood. Once that becomes the norm our electronic "papers" will be about as secure as our physical ones. We're starting to get there. But IMHO we're not there yet.

    Unfortunately we WON'T be fully safe using encryption until the typical machine configurations are such that, if the machines are seized, it will be impossible to recover incriminating data from them - even with passwords browbeaten out of their owners. Until that time it will still be useful to bypass encryption by raiding one of the machines at the endpoints.

    = = = =

    Re the list and "no encrypted traffic": When one of the regulate-the-internet laws was about to make it too much hassle to continue, we closed down the list (after finding volunteers to run its successor and - since the participants hadn't agreed to have their info forwarded - announcing the successor on the original list and giving people time to sign up.

    Now I regularly use SSH to telecommute or to access the primary house machine from the vacation house. But that's still low-profile: It's clear from the IP addresses that the SSH connections are going to the company, coming from it, or coming from a single external dialup machine via a particular service provider.

    Unless they recently changed the Constitution and didn't tell anyone about it then ratified treaties are consider the law of the land and the violation of said treaties can be treated as an impeachable offense. I don't know if this will be the route taken for impeachment, assuming impeachment, but legally it does apply.

    This is a common misunderstanding of the supremacy clause. (A variant is to read treaties as equivalent to constitutional amendment.)

    In fact the supremacy clause is solely about the federal stuff (constitution, laws, and treaties) trumping state law where they conflict. However, note that the constitution trumps BOTH laws and treaties. The constitution is IT. Everything else in the government either derives from it or is null on its face.

    The supremacy clause is solely about the several states having delegated (in a binding fashion) certain of their powers, including their foreign policy, to the fed. Countries regularly abrogate treaties. In the case of the US and its several states the fed has the power to make these decisions and the states do not.

    Ratification requires congressional approval. Abrogation does not. It generally "just happens". (No point in rocking the political boat by by making a big announcement, unless that's expedient.) That means that the Executive branch just stops behaving as if the treaty had any force, and perhaps issues internal directives to that effect. Typically this happens when the other party abrogates their side of the treaty, or makes war on the US. Then the executive branch determines that the treaty is void and starts ignoring it.

    Potentially the Congress might claim some say in whether treaties are to be abrogated. It might mention them in a declaration of war, or pass a resolution stating that one is void. And of course any legislation to implement a treaty needs their action to repeal it or (even if the executive stops enforcing it) it remains on the books (unless the courts strike it for some other reason.) But claiming that the executive branch doesn't have the power to abrogate treaties on its own is a separate constitutional crisis. B-)

    Haven't we ratified the Geneva conventions as well, and ignored that?

    The US ratified the first four (through 1949) but not the last two protocols (1977).

    They are a treaty. As such they are binding on the several states as long as the federal government considers them to be in force. But the fed (like any other government) abides by them or not as it finds convenient, and can declare them null and void at any time it finds convenient. (Meanwhile, treaties have no direct force within the country except through implementing legislation or executive orders. Such legislation is subject to the usual constitutional limits on congressional power. Congress' powers over the other two branches are severely limited. Executive orders are just the orders of a president to his underlings, automatically superseded by any later orders.)

    Further, most of the Geneva Convention protections explicitly are not extended to terrorists and other paramilitary forces that don't themselves obey certain of their provisions - such as identifying themselves, wearing uniforms, not deliberately blowing up non-combatants (who aren't in the way of an attack on a "legitimate" military target), etc. The idea is to encourage everybody else to play by "the rules of civilized warfare".

    Which is not to say that what the administration is doing is the right thing to do. Just that an appeal to the Geneva Conventions is not a particularly useful charge to make against a president and his administration. It's an attempt to seize moral high ground but has no force in law.

    If you want to mount a binding legal attack on a sitting president it needs to be based on constitutional grounds.
