    The problem is that on the battlefield one can not just go back and get another one. When the failure of a piece of equipment may mean someone's death that equipment better work.
    A soldier will not carry around equipment that only works 80% of the time and no good commander would make them.

    Fallacy much?

    So you think a this is the same as this?
    You also need to read a bit more.

    Nothing like ignoring the obvious I pointed out.

    All you said was being dependant is bad. I agree and there are ways around dependence. What did I miss?

    A soldier running a recon mission

    Who said recon mission. It could be a patrol.

    is different than every soldier walking around with a tiny drone tethered to them

    They are not talking about a drone for every soldier all the time but a drone per squad used when needed.

    You are not going to fit much into a small drone in terms of either anti-jamming or encryption.

    Are you an electronics expert who knows what can and can not be done on small chips these days?

    If you think that you can find a sniper with this drone, I have a nice bridge for sale.

    Explain to me how a drone with a camera transmitting back to an operator can't look behind a rock and see anyone hiding there.

    Wrong, it takes very little to detect electronic signals being broadcast.

    Detection is very different that locating the source. The former can be done with any radio the latter requires a lot more equipment. Your car has a radio which can detect radio stations. Try to use it to find the transmitter. See the difference?

    The concept being discussed goes back to the Army (FCS) project work which ended up being cut.

    The FCS program was between 2003 and 2009. Drone and computer technology has come quite a way in the last 6 years. How about you catch up with technology.

    If remote controlled tiny aircraft were better on the battlefield we would not need soldiers at all.

    There is a huge difference between an armed drone and a small recon drone.

    There is a huge issue with putting soldier under the dependency of gadgets.

    True, which is why you train them with and without the drones so they know how to use them but don't become dependent on them.
    .
    Do you see no value in a soldier being able to send a drone into a building or over a hill to check if anyone is in there? Say you were on patrol and ahead you see a spot that would be great for a sniper. Wouldn't you rather send a drone to check it out?

    Soldiers walking around with broadcast devices have no ability to hide,

    They can only be seen by people with sophisticated tracking systems which would actually fail when a number of these things are in operation. I doubt Daesh has any of this kind of equipment.

    they also run the risk of interception and force feeding bogus orders.

    Which is why encryption and jam resistance is important and one reason why civilian drones will not be sufficient.

    Take your $1000 drone and do the following.
    1. Rugedize the controller and drone so they can stand up to battlefield conditions which includes the following: temperature extremes; being dropped, stepped on, etc; waterproof; dust/sand resistant; etc
    2. Make the communications channel both jam resistant and secure.
    3. Make it, including a protected carrying case for the drone, small and light enough not to be a burden.
    4. Go through several rounds of testing and modification so everyone has a say in the design and politicians are seen to be doing something.
    5. Parcel out the production to several states to spread the money around.
    That $1000 drone just got much more expensive.
    The main issue is that military equipment has to work in harsh conditions. On the battlefield you can't say "my machine is not working so I am not going to play today".

  9. Re:3D printers on People Often Deride Game Changing Technology as 'a Toy' (medium.com) · · Score: 1

    On the issue of "toy". What do most people say when they have purchased a FDM printer? It is usually "Look at my new toy".

    Show me a service that uses a uPrint Plus. Notice that it is in the "Idea" line of printers and not the higher quality series.

    But comparing the output quality of a Stratasys FDM vs a well-calibrated RepRap? You'd be surprised which one you'd pick and the price difference between the two.

    Who would build the RepRap for me if I don't have the skill? Who will teach me how to calibrate it successfully?

    It comes down to the fact that if you put your time at $0 doing it yourself will always be cheaper.

    I'm not calculating my time because the parts I make are for personal projects, i.e. it's a hobby.

    By definition a tool used for a hobby is also a toy.

    What commercial services use FDM? The one I have seen use much more expensive technologies.

    One service I called was proud that their Stratasys was able to make 0.25mm layers even though a properly calibrated home-made printer can do 0.10mm layers.

    That is kind of strange since the lowest cost Stratsis, the Mojo, can do 0.178mm layers. This also brings up the question of how hard is it to "properly calibrate" and how long does that celebration last? If it takes hours of setup to print one item it is a toy. Sure, if you compare low quality prints done by a hobbyist and the same prints using similar equipment by a service the hobbyist will always be cheaper. You have to pay something for not doing it yourself.
    There are quite a few services that use technologies other than FDM. I was referring to companies like Shapeways and Quickparts.

    In your cost calculations how much did you figuratively pay yourself? If you valued your time at $0/hr your calculations may be a bit off.

    As for 3D services, they generally have printers that produce much higher quality that desktops can produce. A desktop extruder is very different than a laser sintering printer.

    3D printers is a huge category. There are a wide range of 3D printers from sub-$500 glorified hot glue guns to multi$100K laser-sintering printers. To me, the low end printers are a toy as they have many issue that only hobbyists could love. The high end ones are definitely not toys considering the awesome stiff they can make. Sometimes it is the implementation and not the technology that makes it a toy. For example, the standard household oven is not a toy but the Easybake Oven is.

  17. How is unlocking a phone any different than cracking a safe full of documents?

  18. Since people can move from state to state while using the same phone the Commerce Clause probably comes into effect.

  19. The article quotes the following

    But in exchange, in Section 1002 of that act, the Feds gave up authority to “require any specific design of equipment, facilities, services, features or system configurations” from any phone manufacturer.

    It misses the preceding clause;

    This subchapter does not authorize any law enforcement agency or officer

    Notice that it "does not authorize" rather than "prohibits" and it only applies to law enforcement agencies or officers. There is nothing in it that prohibits another agency like the the Office of the President, as it is not a law enforcement agency from requiring it.

    Also, the term "specific design" is questionable. A specific design would be something like "must use SHA2". It could easily be argued that "access to encrypted data" is not a "specific" design but a "general" design as it can be implemented in several ways and therefore the clause does not apply.

    I am not saying a back door is a good idea but this law does not prohibit the requirement.
