  • Bootstraping is what you are looking for. A lathe is often the start of bootstraping because a lathe can make itself. You can also use a lathe to make a lathe, but if you do it that way you slowly lose accuracy over generations (but it is much faster and so most lathes are made with lathes). By having a lathe make itself you restore accuracy (and if you have learned something can sometimes get even higher accuracy than previous rounds). Before you can make a lathe you need precision flat surfaces, but it turns out only basic tools are needed to bootstrap that (and a lot of time). A lathe is considered a machine.

    The point is that robots can make themselves if you program them for that. I’m making a clear distinction between reproduce themselves and make themselves here. A nearly worn out robot can restart the whole thing (so long as it does fail completely too soon) of making a new robot that is bigger and more accurate than it ever was (if bigger and more accurate is desired by the programming). That doesn’t mean the same robot could reproduce itself, instead it has to cause a robot to make itself.


  • The forces in play have almost nothing todo with trump. Not that I support his policies but anyone looking at harvests would have told you prices would be low. I work for deere - we have been planning for low prices since before it was clear trump would even run (it was expected, but not yet announced). You can read 10k or whatever to see when the public announcements were, but we expected this for a long time and it is playing out within expectations.

    Large harvests mean low crop prices mean farmers have low incomes. basic ecconomics based mostly on the weather. nobody can stop it. there are other factors but they are small against the weather. (We still need a sane trade policy butiit won’t change much)

    any farmer who thinks this is bad needs to looh up 1986. things are just down a little compared to that diaster.




  • Lifetime for security. Other features (new drivers…) you can pay for, but security is lifetime. You need to escrow enough money to provide this service or prove that nobody is using the OS.

    All services required for use of the device are also lifetime - though they may charge a subscription price so long as that price is clear to the customer before the first sale and prices go up by inflation only. After 15 years they can drop the service if it is easy for a “normal user” to switch to a different subscription provider; and all source code required for someone “skilled in the art” to create and maintain their own service provider is publicly released under terms that allow modification and redistribution was released at least 5 years before killing their own service.

    You are allowed to drop support for any protocol that is not latest recommended state of the art so long as you maintain what was recommended at time of release. If a newer protocol comes out you need not support it. (Which is to say you can be IPv6 only today, and if the internet switches to IPv12 in the future you don’t have to support that)

    The above applies to anything network connected. OS, web browser, Security camera, thermostat…



  • my phev is a minivan which I bought used for 25k. The only ev minivan in the us is 60k (just came out so used not available. Those are the real numbers, the engine prices you quote are irrelavent as I’m not buying an engine I’m buying a camplete vehicle.

    nothing to do with the slate, the conversation has drifted. The slate is not available at anyprice today, though it looks like an interesting option in the future.








  • Do you need one? There is a 3d printing service near me that has better printers than I could afford that is happy to print for me. For many the cost of a service is less than printer for as little as they really print so something to think about. Check your options. If 3d printing isn’t the hobby but a means this might be your better option. Don’t forget that once you agree to outsource creating parts you get access to wood, metals, and additional plastics. You also get many more processes (injection molding, lathe, milling machines, SLA/Resin printers) which lets give you many more options. And you get access to machines that wouldn’t even fit in your garage.

    I’m not saying don’t get a 3d printer. For some it is the right decision. I’m saying don’t overlook the other options. Even if you get a 3d printer you should use the other services instead of making everything a nail just because you have a hammer.



  • Parts fail all the time. The problem with hardware raid is you need a compatible controller or none of the data can be read even though it is still on the physical disks. Computer hardware is often only made for a few months before there is a new model and so you are risking that the manufacture really made the new model work with what you have. That is assuming the manufacture doesn’t go out of business which could happen without warning. \

    Also, if hardware breaks that is often a good excuse to replace it - odds are better hardware is available for the same price and sometimes a lot less $ - with hardware raid you are stuck paying whatever price they charge.
