    Again, It's true that some things cannot/will not be made at home, always.

    You're wrong about heat treating, by the way. Plenty of folks out there have set up their own small foundries, and are casting aluminum and iron. Plenty of other folks (like me) have computer controlled kilns for case hardening.

    I think if some complex process is a stumbling block to making a desired item, the designer will try to work around it... redesign a part so it doesn't need the complex process, or substitute a process that can be performed simply. If you post on certain engineering or DIY boards online with a challenge like "design a toaster that can be built with hand tools" you'll get 20-30 people giving it a shot.

    I'm not saying that grandma is going to have a forging press in her living room. I'm saying that there will probably be a couple of people living in her town that build things, and then a couple more, until down the line the "best" stuff won't come from big factories, but from small shops. eg. look at the high end bicycle world... all the top of the line stuff is from tiny makers who specialize in a small list of items.

    There's a world of difference between benchtop tools and small CNC. The latter requires far less skill to produce far more complex parts. More to the point, CNC permits easy replication or repeated parts with high tolerances. Make one for yourself, and one for a friend.

    There'll always be professional engineers and drafters, but there are also people who love to design things for free.. witness the availability of free CNC machine designs online, and patterns to run on them. Or free software, for that matter.

    Woodwork and metalwork are apples and oranges. You can make some nice things with wood, but unless you love having nice furniture, the options are limited. For metal though, you can make machine parts that will handle large forces and wear well.

    Note that I'm not saying that all things will be made at home... just some things, enough to turn the economy on its ear and change the way the government has to try to control objects... which is a futile endeavor anyway.

    A huge trend in the near future (0-20 years) will be home and distributed engineering (inventing) and manufacturing. People will trade information on technologies, how-to information, plans, and parts to make sophisticated products in their home or workshop.

    This is not to say we're all going to get replicators or nanotech manufacturing like in "The Diamond Age" but the level of sophistication of home built products is going to go way, way up. From small appliances to tools to vehicles to weapons, it'll be possible to make a large number of items in places other than traditional factories, in small quantity and high quality.

    To see this sort of thing emerging, look at efforts like Reprap to make a self replicating 3d prototyping machine (which probably won't be 100% self replicating for a long time, but which is a great starting point for at-home applications of the technology) or home CNC machines like router tables and small CNC machine tools. You can buy a CNC milling machine capable of producing small parts eg. for firearms and small engines for less than $3000 with computer. Once these become widespread part libraries for them will be as available as clip-art. Want a new part for your bicycle? Download the pattern, place the raw material in the machine, and walk away.

    As quality items become harder to find in mass produced outlets, items made at home will take their place. Any item with a niche market will probably be made in these mini manufactoria... there won't be a profit any more in making small quantity items since there'll be tremendous competition from small manufacturers.

    No need to keep an inventory of obscure auto parts on hand (or to pay for storage space or sunk costs in the inventory). Just keep the pattern available and churn out parts as needed. Need a part you don't have a pattern for? Ask someone on the internet to measure their part and make a pattern from it, using the same CNC mill to automate the measurements.

    I like the trend myself... but can you imagine the fit the government will throw when it figures out it can no longer regulate eg. firearms because anyone with a CNC mill can turn one out in a day or two? I can see them at first trying to ban home manufacturing, trying to ban precursor items and materials, then trying to create an overarching government agency to police the whole thing.

    It'll be similar to recording companies figuring out they're no longer needed since anyone can distribute or purchase music on-line without their involvement.

    Likewise I can see large corporate manufacturers of some items begging for a government bail-out because no one wants to buy their mass produced crap any more. Why pay $100 for a cheap wal-mart bike when the CNC machine shop in the next town can produce one with 3x the quality for the same price? Why pay a computer store $35 for a plastic keyboard when you can get a solid brass one with better components made at home?

  5. What you should do is adjust your thinking on Android's Success a Threat To Free Software? · · Score: 1
    This is a fine illustration of the mindset of a lot of Linux and open source "fans".

    There's a self identification happening here with the "open source community" for a number of reasons, and it's a common occurrence among a lot of open source advocates. What usually happens is that fans end up with a binary view of the software production system... specifically the idea that there exists an "us and them" conflict between open source and commercial software, and between the authors of same. It's kind of the same impulse that makes people identify with a sports team based in their city or state as "their" team, or advocating their own brand of computer for emotional rather than rational reasons.

    Humans want to belong to groups, they get a good feeling from it. So even in cases where clear "us and them" groups don't exist, they perceive them, since without a group they have nowhere to belong.

    There are a lot of reasons for this both biological and social. The phenomenon seems to be a human universal, though.

    To make things more complicated, once a person identifies his or herself with a group, then they personalize attacks on or praise for that group themselves.. it's a major reason they want to belong in the first place, since it can provide immense positive feelings with little effort, and can provide them more often than a single person's efforts alone would.

    This personalization usually means whomever is involved can no longer be effectively reasoned with where the group, it's attributes, or goals are concerned. This is because either consciously or subconsciously that person feels threatened by any suggestion that the group is "wrong" or incorrect, or even worse that the perceived group doesn't exist.

    So, in this case the submitter is assuming that the rest of the folks here on Slashdot are A) Aware of the "us and them" groups, B) Part of the "us" group, and C) Also concerned about this "issue" which has been brought to light (probably only partly for advocacy reasons... another large burst of good emotional feelings comes from actively representing the group to which one belongs, and warning of impending doom is a good way to represent. See also the football fans that paint themselves and wear their team's colors.

    The truth in this case is that there are many more parties involved than just two, and that the assumed conflict doesn't exist. If one looks back to the origins of the free software movement, there were no restrictions placed on commercial use of the GPL software (or its predecessors). In fact, the GPL allows commercial use of licensed software without fee or restriction except for the provision to distribute source code.

    The hard thing for a lot of people who are concerned about this "conflict" to wrap their head around is that there's no conflict, and in fact commercial software stacked on top of open source is a very good thing for any open source platform... it means everyone wins. People can make money off of their work, other people can get commercially supported apps they need, and no one is held hostage to a closed source operating system or distribution method.

    Imagine what the iPhone would be like if Apple didn't control the OS, and wasn't able to control the software written for the device... there'd be far fewer $9 apps that are crap since someone would immediately write something better, and having no one to say "no" would get it published.

    To use a car metaphor, buy a VW Beetle and ask them if you can go off-roading with it. They'll tell you not to do it. If you say, "I'll get big shocks and knobby tires", they--and your insurance company--will tell you that it's not supported. If you do it anyway, and take it to a location where it's legal to do that kind of driving, VW's not going to stop you. Same thing here. Difference is that VW will actually void your warranty. With Apple, you can re-set to factory defaults and everything's still intact.

    This is kinda apples and oranges, but I'll go with it a bit.

    The difference between iPhone and VW is that Apple's not just dictating appropriate and safe use... if I wanted to use my iPhone as a pacemaker they'd be quite right to void my warranty and run screaming from the whole idea.

    What they're doing, though, is more like dictating what appropriate use is, apart from simply letting common sense and consumers decide.

    To use the VW analogy, it would be like VW requiring VW only gas to be used in their cars, which is more expensive and harder to get than non VW gas. Even though chemically identical and quite usable non-VW gas is out there, and some of it might offer more horsepower or cleaner emissions, VW would threaten to void your warranty if you used it and would verify use via an internal sensor in the gas tank.

    The thing that makes this behavior unacceptable isn't even the whole "VW only" rules and mechanisms described above, although it's a red flag to me. It's the reason VW would do it... to preserve their control of their cars and how they're used, because control means more profit for them from "VW Brand" gas and the ability to alter that fuel's composition or delivery mechanism as they see fit.

    Apple isn't trying to keep consumers safe or indicate which uses of its products will result in damage to them or injury. They're exercising a level of control over items no longer theirs that no manufacturer should have. It'd be different if they were up front and said something like "You're not buying your iPhone, you're just leasing it from us..." but they're not. They sell them.

    When I buy something, it's mine. So I'm going to show my disagreement with their behavior by not buying their products.
