  1. Re:Rocket engines on NASA Considers Apollo-Era F1 Engine For Space Launch System · · Score: 1

    You are talking two different things here with this "junk yard" called Norton Sales.

    First, there are hobby rocket builders who scrounge through that junk yard for parts because they are building one-off specialized rockets on an extreme budget and are largely garage tinkerers anyway. I know guys who have done that for automobiles, tractors, and other kinds of equipment too for largely the same reason.

    As for NASA going through that place to dig up parts, they are either looking for engineering samples to act as a comparison when trying to rebuild old designs, or perhaps they are desperate in terms of looking for a specialized part that has been discontinued from the original equipment manufacturer yet functioning equipment still needs those parts for some reason. Rather than paying a machinist or that original company a huge pile of money for a production run of just one part or a very low number (yes, that sometimes does happen both in NASA and the military for many items), searching through a junk yard like this would be hugely cheaper.

    It isn't that people are too stupid today to be able to build this stuff, but that it is simply cheaper to get stuff from a junk yard. Cheaper by orders of magnitude I should add.... as long as you can even find what you are looking for. If they can't find it at that junk yard, they simply are forced to try and make it from scratch instead at considerable cost. Sometimes a production run of one item can be nearly the same cost as producing thousands of that part too.

    It depends on how far outside of the law that the individual patrol officer happens to be at the incident. There was one real jerk of a sheriff deputy near where I live that was pulling over attractive women and then raping them under the guise of doing a "drug check" or some other nonsense. That officer finally got his ass nailed and is serving time in the state prison. I also had an officer get chewed out by a supervisor because of some mischief he was doing to me personally.... where he called in his supervisor to whitewash his mischief and the effort backfired on him in a very public way.

    While certainly not perfect and yes there is the "blue wall" where officers will tend to back each other up instead of correcting some abuse, in a competent and professional police department you can request that a supervisor show up to review the actions of an individual officer. If it is something more involved than a speeding ticket, that will likely happen anyway but it is nice to be able to do that. It is also an important check on the behavior of police so they don't let their authority go to their head either.

    Wrong. A policy infraction can result in disciplinary action (termination, leave without pay, etc.). A law can result in legal action (fines, jail, etc.). A policy cannot itself result in legal action, unless the policy reinforces existing law.

    There's a policy at my job (in government) that disallows wearing shorts or sandals in the office. I cant be fined or arrested if I fail to comply.

    On the other hand, if there is a policy in place against wearing sandals in the office because you need to be in places where there is some sort of danger of some sort like perhaps a need to wear steel toed shoes, by disregarding such a policy you also don't get the protections which come from such employment either like being able to make a workman's compensation claim against your toes being amputated due to a reckless disregard of company policies in that matter.

    Yeah, most office jobs the largest danger is perhaps a paper cut, but not for everybody. Police do engage in stuff that is slight more dangerous as a normal part of their day job too. As suggested above, it also personally opens that police officer up to a liability lawsuit when they flagrantly disregard department policies, and not only can they lose employment but also pension benefits. Police also have a higher standard where committing certain acts is not just against policy but also illegal.

    Taking property from a citizen at gunpoint in a manner that is contrary to department policy is a bit more of a big deal than wearing shorts into an office as a bureaucrat who mainly pushes paper.

    Under criminal law, the most that happens is a hand slap where the evidence is thrown out if it is to be used in a criminal prosecution.

    That is also sort of the point of the lawsuit mentioned in the article, where what is being alleged is that the police of Washington DC are routinely confiscating property without due process. They don't necessarily need a judicial order, but they do need probable cause that the property is being used in the commission of a crime, and in order to keep the evidence for any length of time that charges will be filed.

    There are legitimate reasons for police to seize property without a judicial order, or do you think that lunatic in Aurora, Colorado should have kept his guns, ammo, and bombs even after being arrested and keeping them inside of his jail cell? The question is where do you draw the line from something painfully obvious like taking the gun from a lunatic who is shooting everybody in sight and then to taking a camera from an otherwise innocent bystander who is merely recording the reaction of the police to a criminal act?

    It could be argued in both cases that a judge could still be called upon to issue an order for the items to be collected and that all a police officer could do is to simply "secure" the property to make sure it doesn't get lost or destroyed.

    Okay, do you have any evidence for that?

    Absolutely I have evidence for that. The fact is that a great many patentable ideas are indeed published in "open sources" (various uses of that term including pure "public domain") where those ideas are freely shared with anybody who wants to use them. Operating systems like Linux, to give an example, depend upon patentable ideas to explicitly be shared without any kind of monopoly being granted or even explicit expectation of getting monetary compensation for the work they do, at least in the traditional sense of software or equipment manufacturing.

    Trade journals of a great many professional journals also include "how to" tips and tricks including schematics, drawings, and other related technical information for things that in theory could be patented but simply aren't.

    The fact that it is happening anyway in spite of the patent route happening certainly shows that patents are not necessary for useful ideas to be disseminated that will advance an industry. I'm even going so far to suggest that the patent system is indeed a brake upon that dissemination of information for most industries, and most especially the electronic and computer industries in particular.

    Considering that for nearly the first 30-40 years of the computer industry software concepts simply couldn't be patented at all, that hardly stopped the development of innovative software ideas such as the development of real-time computer operating systems, time share terminals, compilers, and the development of thousands of computer programming languages. I would say the onus is on you to demonstrate how the progress of the computer industry has been improved in any way since software patents became widely used and I'd even go so far as to suggest that the exact opposite has happened.

    As has been mentioned even earlier, the fashion industry doesn't have patents, and neither does the film industry with the exception of technical aspects like camera designs. If a filming technique could be patented or a performance style, you would see similar kinds of problems plaguing the film industry that current infects the software development industry right now and would be equally silly as well.

    You certainly aren't making your point about the usefulness of the patent process itself or why it should be used instead of publishing the idea in an industry trade magazine or journal.

    In fairness, what happened was that some bureaucrats at the FEC proposed legislation that was sent to members of congress that subsequently changed the laws to get rid of stuff like members of congress pocketing the campaign financing. It went through congressional hearings and the full legislative process in Congress including the President's signature in order to become law.

And I've had offers from groups that I most certainly didn't agree with for money I could have desperately used in order to finance my campaign.

    While the laws have changed somewhat since this practice was happening, there was in the past an option for federal office holders (Senate & U.S. House) to be able to pocket excess campaign donations after they were defeated in an election or went into retirement. This still is the case for some state and municipal office seekers (and certainly was in my case when running for municipal office). I had to report all of the donations of course and file formal reports on all of the income and expenses (which typically break even if you are being serious about a campaign), but if a "generous donation" was to fall in your lap, it certainly could end up being something very much like a legalized bribe.

Without them, the profit motive would encourage trade secrets and hoarding of information and techniques. Say what you will about patents, obviousness, and longevity of protections, but they have succeeded brilliantly at getting everyone publishing everything in extensive detail.

    If that is the goal of patents, it has become an utterly failed goal and the role of the U.S. Patent and Trademark Office certainly has not encouraged any actual documentation of the devices or concepts themselves. Sadly, I've read enough patent applications to realize that there is no possible way to glean much of any information at all from those documents in terms of being able to actually build the devices or concepts being described in them. Those applications are so full of legal descriptions that gleaning any technical data on how to do something simply can't be done.

    I'll also note that if patents were so excellent as a means to share and distribute information about technical and engineering concepts, most engineers would have a bookshelf and likely even a full library of patent applications (especially expired patents) for them to review and to get ideas from. Instead, most engineers are explicitly encouraged to never read patent applications except in a narrow scope to help out with the legal defense of a company once they have been sued or are supposed to be giving expert legal testimony on the content of the patent. The only patent related items that you will ever see in an engineering office may be some plaques honoring employees who have been granted patents, but you would typically see lawyers who see any other patent applications or grants that belong to other companies taking those materials and throwing them into the shredder or burning them with likely a long talk to any engineer who is caught with them in a joint conference with a human resources exec, the immediate supervisor, and a lawyer along with some sort of form where that employee would have a long and embarrassing "lecture" (it wouldn't even be a conversation) and they would need to sign some paper as a condition of employment to never look at another patent application without direct approval of their supervisor.

    I wish patents would work as you claim. It is a noble thought and if patents actually functioned as you claim the world would be a much better place. Sadly, they fail at the thought. The details about how to do what they claim to do is almost never there. If we had to re-create 21st century American technology out of the data base that is the USPTO patent applications, we'd still be stuck trying to figure out how to chop down a tree much less being able to build a fire or even building any of the tools that make America work today.

    If you want to share information about technology, try a textbook or some technical manual. They are embarrassingly better at sharing information about technology than any patent ever could think about, and would tell a would-be engineer how to actually accomplish the task rather than the legalese which is a patent application.

Because the fact is that I'm MUCH more afraid of well-meaning--but stupid and untrained moron--hurting or killing me with a gun than some nutjob opening fire in a theater.

The government should be afraid of an armed citizenry, but the fear is because that government is kept in check by that citizenry from doing stupid things.

Classes that teach firearm training are fairly easy to find if you really want them, and a good firearms instructor can not only show you the proper way to use those devices without hurting yourself in the process, but you also learn very quickly that where you point a gun, regardless of the fact that you may think it is unloaded or even if your hand is nowhere near the trigger, you should expect that the gun will go off at any point with a bullet and strike whatever happens to be in front of that muzzle. NEVER point a gun at somebody unless your goal is to literally kill them in hopefully a self-defense purpose. Don't screw around and joke about such things too and be extremely serious about how you use firearms because they are serious devices that can cause a whole bunch of damage if misused.

    Sure, other kinds of equipment (notably automobiles) can also kill people if misused (the accused assailant in the theater could have simply crashed his car into the theater at 70 mph instead of using a gun and caused nearly as much damage). I remember kids that screwed around in shop classes when I was growing up, and ended up injuring themselves on some of the power tools, so I know stupid people do stupid shit with dangerous equipment simply because they want to joke around. Real life isn't a video game and you don't get a second life if you screw up.

    All this said, there is even a constitutional provision for the training and enforcement of firearm regulations, and that would be through the use of state-chartered militias. For myself, I would even be fine if the only people who could possess firearms would be regular members of the militias, at least in America. This is not some group of nut jobs who go off to the woods and run around in uniforms of their own design and pretend the end of the world is here or planning for a nuclear holocaust, but rather legitimate groups of ordinary citizens who receive proper training on firearms from skilled instructors and are part of an organization which is formally recognized by a state government.

    It may not be the same as what GM is doing, but you can't say it is the only one "in the business", unless somehow GM thinks they are the only American auto manufacturer making electric vehicles. I'm sure Tesla and Fisker would disagree with even that sentiment.
