    This has missing tags, right?

    I'm not a lawyer either, but have been through this. As others have pointed out, patents have a finite life but copyright is basically forever. If it gets to court, the only legally safe approach is a standard clean room implementation: one person/group read the copyrighted code and wrote a spec, a non-overlapping person/group wrote all new code from that spec. Be prepared to show your version control history to the court to demonstrate that you started from scratch, and explain to the court the process you used to limit communication between the two teams to the spec itself.

    Can I produce a printed circuit board this way? Full meaning traces, plated-through holes, solder mask, silkscreen printing. Doesn't have to be particularly rugged; FR-4 is overkill in terms of strength for most people. If you could keep such a machine busy, how expensive would the results be? Just wondering about the business opportunity; sending designs for simple one-offs to China for fabrication through a consolidation service like BatchPCB has always seemed extravagant in some fashion.

    And forget manufacturing metal spoons unless you're willing to invest in blocks of stainless steel and a plasma cutter.

    Direct metal laser sintering machines are already in commercial use (article with pictures of produced items here) that could manufacture metal spoons. Current metals in use include stainless and maraging steel, and titanium alloys. In theory, almost any alloy could be used. I have to believe that machines built around 200-watt lasers, and properly prepared stainless steel powder, are beyond the budget of most hobbyists who would be interested in making spoons :^)

  8. Re:yea uhhhh on Can Long Term Research Survive the Coming Age of Austerity? · · Score: 1

    At least arguably, the golden age(s) of private sector research all required government-granted monopolies (at least in the form of critical patents) to generate the necessary revenue streams: Edison, AT&T's Bell Labs, RCA's Sarnoff Labs, Xerox PARC. Critical research in the aerospace industry was funded by the military. Some will argue that even large-scale integrated circuits would have gone nowhere without government funding (personally, I disagree with that one). Many of these operated with what was pretty much a swinging door between the private research labs and positions in academia.

    Notice that even today, the firms that are funding large amounts of research -- Intel and Microsoft, for example -- are so large that they are, or have been, under investigation for antitrust violations.

    Ummm...I don't have a black asphalt roof on my home in Mesa, AZ. I have clay tiles.

    IIRC, one of the reasons that traditional clay tile roofs have been around so long, particularly in warm climates, is that there is a continuous flow of air between the tiles and the underlayment due to natural convection. The tiles may get quite hot, but the air flow keeps most of that heat from reaching the rest of the building.

    I think it costs more to cool down than to heat up...

    Lots of considerations go into that question. What kind of climate is involved? Very different answers for New York City and Houston. Different answers for inner city versus outer suburb, based on the "heat island" effect. Different answers if the weather pattern is sunshine in the summer and cloudy in the winter, or vice versa. Also depends on the technology that get's used for heating or cooling. An old oil-fired furnace in a climate zone with cold winters is going to make for expensive heating. A high-efficiency heat pump in Seattle or Portland with cheap hydro power is going to do the necessary heating for a lot less money.

    The big thing about the white roofs in an inner city where the "investment" is basically a coat of white paint is that the materials are cheap and no skilled labor is involved.

    Yeah, the best-run large company I worked for was run by a business PhD who had spent some years working his way up through management at another large firm before winding up as our CEO. The business didn't develop new technology, but the services we sold were highly dependent on technology development. I was on the staff as a tech analyst: what's possible, what's not, is the pure tech company that's selling us gear blowing smoke, etc.

    The really amazing thing about him was that he got the different organizations to not only talk to each other, but to work together. Our tech organization would get calls from the MBA types, asking for someone to come to meetings to provide an informed tech opinion (and they listened!). We had good relationships with marketing so we could talk to them about the problems that might be encountered if we rolled new tech into the field. Billing and customer service types were brought in at the beginning of a project, rather than as an afterthought.

    We weren't the biggest business in our field, so eventually we got bought by one of the bigger firms. Who immediately started building walls between the organizations.

    Yes. If nuclear is going to be part of the long-term solution, then thermal neutrons have to go. Fast neutron reactors that can burn everything except the short-lived fission products, and that can do breed-and-burn of the million tons of depleted uranium the US and Russia have in storage, are critical (no pun intended). With my cynic hat on, I note that Bill Gates has funded design and simulation studies of one such fast-neutron reactor, and would probably like the government to fund the first working model built from the design rather than paying for it himself.

  18. Re:We've been an Advanced Circuit customer for yea on How Printed Circuit Boards Are Made · · Score: 3

    Fabrication, or the actual design? For fab, and if you have the time, Batch PCB does boards for $2.50 per square inch plus a $10 set-up fee. I did a couple of small simple boards through them earlier this year. Once I passed the automated design rule checks (easy for simple boards), 17-21 days from submission to finished boards in my hands. Production is in China, but the quality was more than good enough for my needs. In both cases, I ordered two copies and received four. Apparently there is some duplication as things are panelized and produced, and they send along the extra copies rather than discarding them. No testing, but all of the boards I received worked.

    They use Gold Phoenix for the actual production. If you need enough copies to fill, or even mostly fill, 100 or 150 square inches, it's cheaper to deal with Gold Phoenix directly. Other people have suggested DorkbotPDX; their prices may end up cheaper, but it appears to take Dorkbot a long time to fill up a panel; BatchPCB seems to fill a panel every couple of days.

    Short of locking him up, how is the state going to stop him from committing suicide? Everything you need for a quick painless death is available from your local well-stocked welding supply shop: a small tank of dry nitrogen, regulator, tubing, and breathing mask. Set it up so the mask is at a slight overpressure and you're in business: pass out after 30-60 seconds, heart stops beating with no chance of restarting after 10-12 minutes. Total cost probably less than £100.

    How effective is it? One of the reasons that Halon fire suppression systems were banned was that leaks resulted in odorless Halon pooling under raised floors, and techs working on the cabling passing out and suffocating when they stuck their head down into the pool.

  20. Re:Striesand Effect on State of Alaska Prints Out Palin's E-Mails; Online Distribution 'Impractical' · · Score: 1
    I pulled up the Alaska open records statute. IANAL, but have previously held a position in state government that required me to render opinions as to the meaning of particular laws. Here's the first paragraph, which lays out the basic requirements:

    Unless specifically provided otherwise, the public records of all public agencies are open to inspection by the public under reasonable rules during regular office hours. The public officer having the custody of public records shall give on request and payment of the fee established under this section or AS 40.25.115 a certified copy of the public record.

    "Inspection" is almost always interpreted to mean "You can look at a paper copy." The agency is not required (or allowed) to provide you with access to their computers, microfiche readers, etc. "During regular office hours" is almost always interpreted to mean the person making the request has to come to the state agency to perform that inspection or pick up their copies. But the real kicker is the phrase "shall give... a certified copy". To quote from Wikipedia, a certified copy "has on it an endorsement or certificate that it is a true copy of the primary document." No choice for the agency — they have to certify any copies they provide.

    A downloaded copy is certainly not certified, so agencies are simply not allowed to do it that way. A write-once CD might be certifiable, so long as the courts have interpreted the law to mean that a single certification can be applied to a large collection of documents. If the individual documents (ie, each e-mail message) must be individually certified, paper is the only practical way to do it.

  21. Electronically doing this is not an option.

    Nonsense. Historical redaction fiascos involving soft copies of documents occurred because people were too stupid to realize that simply adding a black rectangle to the document didn't remove the obscured text. Adobe Acrobat includes a set of redaction tools that replaces the redacted content with a placeholder such as the traditional black rectangle. Microsoft offers a free redaction add-in for Word that removes the redacted text from the document so that it can't be recovered. Redact-It sells a product that reliably redacts text from documents of various formats, including Outlook messages.

    In the programming world, I always got the impression that, collectively, we respected the self-taught coder more than one who spent four years in school being spoon fed how to code.

    Depends.

    Much of my career was real-time programming, both hard and soft. In many cases, one of the critical questions the programmer needed to be able to answer was "What's the worst-case run time for this code?" The person who spent four years in college almost certainly has been exposed to computational complexity and analysis of algorithms; the self-taught coder, probably not so much. Or the (typically) opposite side of the coin that may crop up in embedded systems: speed is not critical, but we're damned tight on main memory, how can you pack the needed functionality into less space? Again, the degreed person seems more likely to have been exposed to concepts like special-purpose languages and virtual machines that may provide the answer.

    Clean room implementations generally protect you from copyright infringement. From a legal perspective, patents are a different beast altogether. If I hold a valid patent, your independent invention of the patented device/algorithm/whatever infringes. The only way you get to legally use that independent invention is to either (a) invalidate my patent or (b) get a license from me.
