  1. Re:A bit late? on Seinfeld's Good Samaritan Law Now Reality? · · Score: 3, Informative

    In Australia we have a shield law for good samaritans. There are three caveats required to invoke the shield law:
    1. You must be acting reasonably (although this is to be interpreted in the favor of the good samaritan if in doubt).
    2. You must not act without permission, although you may assume you have permission if the victim is unable to give it.
    3. You must not be performing something for which you are professionally trained and the act you are seeking shielding from is something for which you could be held liable for under that training (eg. doctor committing mal-practice).

    The first test came when a good samaritan ripped a lady's top off to be able to perform CPR (she had had a heart attack and collapsed on the street, and her bra was impeding his effort). She sued him for exposing her in public, and the shield law meant the case couldn't even be heard. IANAL but I understand from my first aid instructor that you are legally shielded against all possible consequences; criminal, civil, procedural, and anything else you can think of.

    I understand we also have specific crimes along the lines of "Indifference" and "Aggravated Indifference" which mean you can be held criminally liable for not helping, but a paramedic I know tells me that this is based on your level of training: an average person is expected to call 000 (our 911 equivalent), while a doctor is expected to stop and lend full medical assistance, and a soldier would be expected to intervene physically if the odds meant his own safety wouldn't be compromised. He (the paramedic) said that he was unofficially instructed to GTFO if he ever witnesses an accident, because legally he MUST stop and render medical assistance, but he could be held liable for screwing up first aid and his professional indemnity insurance wouldn't cover him (as the incident wasn't "on the job"). IOW it's better if he was just "never there".

  3. Re:It's the Medium on FTL Currents May Power Pulsar Beams · · Score: 2, Interesting

    My understanding from the intro subjects I took while avoiding doing my advanced engineering electives is that while the speed of light in a given medium can change, the speed of light in a vacuum is the c we're talking about when we say you can't go faster than it.

    From wikipedia:
    "It is important to note that, at a microscopic level, the speed at which the photons travel is always the same. That is, the speed of light, commonly designated as c, does not change. The light appears to travel more slowly while traversing a medium due to the frequent interactions of the photons with matter. This is similar to a train that, while moving, travels at a constant velocity. If such a train were to travel on a set of tracks with many stops it would appear to be moving more slowly overall; i.e., have a lower average velocity, despite having a constant higher velocity while moving."

    So the speed of light isn't actually changing in the medium; only the aggregate observed speed at a macroscopic level. Microscopically, light always travels at the same constant c, and the refractive index is reflective of the property of the material which tends to make the light take a longer path. The longer path results in the group velocity being slower than the individual velocity.

    Wikipedia's information on negative-index lightspeed is much more opaque (pardon the pun):
    "However, group velocity can become negative, and exceed the velocity of light c, in the particular case of anomalous dispersion. As a result, a burst of a laser's pulse will appear to exit the rear side of the negative index metamaterial before the laser pulse appears to enter the material. However the speed of transmitting information is always limited to c."

    This result, as described, seems as though you ARE transmitting information faster than c, and I suspect the author of the wikipedia text realized this and just added the assertion that it doesn't, rather than re-working the example so it's correct. Alternatively, the 'observation' of the beam leaving the material before it entered it is an artifact of the observation process.

    I would suggest that, based on the mechanism for the apparent slowing of light in a standard material, nothing about a negative-index material should be able to actually SPEED photons, as nothing in a normal material actually SLOWS photons, but I feel like I'm using wikipedia to falsify itself, and you could argue about the reliability of my source.

    To sum up:
    There are three 'velocities' of interest wrt light: phase velocity, group velocity, and photon velocity. Any of the former two can, in exotic setups, exceed c (and I do NOT grok the consequences); the latter is always precisely c.
    The speed of propogation of information seems to be limited to the lesser of: 1. The photon velocity, and 2. The greater of the phase and group velocity.

    Don't ask me to back this up; I've already exceeded the limit of MY speed of propagation of information (from wikipedia to brain).

    Which is why open-source should work well. Test it slow-and-crappy, polish, and get to the point your risk is much lower in getting something printed. I'm not saying you can do anything on a breadboard, just that you can do lots of interesting stuff on them, and you can definitely do a lot of your preliminary debugging for all sorts of projects. This massively reduces the risk that you'll end up shelling out $100 bucks a few times over for buggy PCBs. Iteratively design and 'release'-early-and-often, iron out all the wrinkles, and then (hopefully) you'll have a community starting around your design and can get together to buy a whole panel of the things.

    And >8 bits? I hate wiring up busses, and even I don't start complaining until we hit at least 16 bits, and a few devices hanging off them. Spring-loaded sockets and good single-core wire just makes it so easy. Admittedly, if you start hanging >~5 devices off them, even 8-bitters can start to suck.

    Oh, on the off-chance anyone reading is still shelling out $$$ for packs of breadboard wire: go buy a couple of meters of single-core CAT5 from somewhere that sells it that way. Give your little sister a set of wire strippers and like $5, and you can have ten times what you get in those little packs that cost like $10 for pretty much the same price.

  6. Re:wrong question on A Critical Look At Open Licensing For Hardware · · Score: 1

    I agree on the 2nd point. There wont be liability for a *design*. Its the people that build it that are responsible.

    And maybe not even then. Working in finance, I had it drummed into me to do two things with every decision:

    • Risk Analysis
    • MORE Risk Analysis

    As it was explained to me, if I (representing my employer, not personally) chose to buy a linux 'widget' that we dropped into our product, off a company which specialized in selling linux widgets, and it failed, costing our customers millions, the liability would pretty much go like this:

    Did the vendor specifically warrant the widget to be suitable for processing millions in financial transactions in our precise environment, and I checked it out with a quick rule-of-price ($50 bad, $50,000 good)? --> I made a good choice, the vendor screwed up. They're liable.

    Was the widget just a widget, which we shelled out $X for and got our $X worth out of it, but it turned out to be unsuitable in some specific way for our use, though probably good enough for 99% of the people who do buy it? --> I screwed up, and should have realised that I really should have spent 100*$X on something much more enterprisey, which would still not be warranted for what we did with it, but at least I could point to how much we spent and have some argument that it should have been better.

    While this doesn't excuse overt lack of safety or total unsuitability for the purpose it's being sold for, I can imagine examples like this:

    Widgets Inc builds cheap crappy carputers from an open-source design. SomeDude Pty Ltd on-sells and installs them. Jim gets SomeDude to install it in his new Ferrari, and SomeDude tries to tell him it's not designed for that. Jim crashes because the carputer isn't designed for Ferraris. SomeDude still has copies of correspondence where he tried to talk Jim into buying a much more expensive alternative which is safe in Ferraris, but eventually agreed to do the install to avoid Jim just trying to do it himself anyway.

    At the very least, the manufacturer is definitely not liable, and there's a good chance the installer isn't either. IANAL, but this is roughly the example I got in my training when I got into financial software.

    Basically, the up-shot was 'you get what you pay for' - not quality-wise, but liability-wise. More money = vendor implicitly accepts more liability. This is why big government agencies and massive corporates pay silly amounts of money for simple stuff: when it fails, they want to say "We paid $3,000 each for these toilet seats! We had a good solid expectation that even though they appear to any scientific test to be identical to $300 ones, that they should be much safer, and the embarrassing injury caused to our esteemed VIP client is certainly not our fault. We spent every penny we could to ensure his behind was perfectly safe!"

    Cisco does prototype rounds. Backyard electronics uses breadboards. The applypower-debug-applypower cycle is pretty fast too, and debugging involves probing with a multimeter (try your local electronics store: crappy ones which are good enough for most projects are <$30) and moving some connections around.

    Manufactured prototypes are the equivalent of doing a full installer-build, burning to CD, and installing on a fresh machine, not compile-debug-compile.

    Working with prototypes is 'nicer', but there are plenty of quick and cheap options available to the hobbyist electronics designer. There are also plenty of free design tools for electronics, once you get to the point you need one. Cross-compilers are everywhere, and the free PCB layout stuff isn't terrible anymore. There are PCB manufacturers who don't even have Protel these days.

  8. Re:wrong question on A Critical Look At Open Licensing For Hardware · · Score: 2, Informative

    I designed a bit of control hardware which I sold to a national coin machine manufacturer a few years back. I spent months wiring prototypes up, and I even had a working model running across several breadboards. I re-used the breadboards and most of the components building other bits (half the components are now in a vero-board car alarm in my mazda.) The total cost for link wire, breadboards, a good stock of components (hint: $2 'random bags' from your local component store), a multimeter, and a DIY programmer kit from a Chinese drop-shipper cost me maybe $200 all up. Component manufacturers will often send you free samples of anything you can't afford if you say you're working on a new product. And when you're done and bored with the project, you can pull it all to pieces and go build something else.

    Compared to the laptop I bought to play Red Alert on during boring engineering classes, the total investment in gear to work on hardware designs was very low.

    Now you won't want to go building a bunch of the things on breadboards, or even vero, but we're talking about open-source design, right?

    Finally, open-source software doesn't usually make the author money by selling the software. Most of the mates I have who do lots of open-source work do it either because they're interested in the project and want to improve it for their own use, or else they like having lines like "Commit privilege to the linux kernel source" on their resume.

    I always envisaged open-source hardware to work by the design being published and expecting users to take the manufacturing effort away from the people doing the designing. It's an upside, not a downside, unless...

    You're not really that into open-source principles, you're into money-source principles. You want a bunch of (almost-)free labor to improve your crappy hardware designs, but you still want to lock people into buying trashy over-priced hardware from you. Don't "Ask Slashdot", ask "MadeInChina.com". The labor is slightly more expensive but not much, and they'll really and truly promise not to nick your IP, and pretend to let you have world-wide exclusive rights to selling the widget they designed for you.

    Having come from a business in the financial industry who spent years angsting over Linux, I've got a different perspective. We weren't just out to convince consumers; our potential customers weren't the ones we needed to ultimately keep happy. Our 'Do or Die' audience were the major banks, MasterCard, VISA, First Data International... And these are very risk-driven places. Not risky - if anything, risk averse - but mostly just risk-focused. In these risk-focused organisations, relative newbies like Solaris are only treated as acceptable because they come from the SunOS heritage. Their risk is somewhat well understood.

    Oracle makes database software. Other people just shuffle bits around somewhat haphazardly and hope the information stays put. They understand the risks of Oracle. Moreover, they all speak the common language of Oracle Risk - they can talk between themselves with that as a baseline, and not waste tremendous time justifying.

    We were looking at slashing our software budgets by hundreds of thousands of dollars (which represented well over 90% of our total OTS software budget!) by going to RHEL and MySQL. All the feasibility studies said they would still exceed our requirements, just as Solaris and Oracle did.

    Result? No go. It was mentioned at the corporate level, and we got our mandate. The big banks don't rely on Linux or MySQL, and nor will we. How can they sit in the corporate box at the racing and meet the other bankers' eyes, knowing that they're on the well-known, stable Oracle, and we're just on MySQL?

    The concession I eventually got was if I can find three reputable banks owning to using both Linux and MySQL, we could look at switching, and it would go from "cheap and risky" to "cutting edge". I moved on before that happened.

    If all of the banks follow similar rules, it'll never happen.
