    If all basic needs can be handled by redistribution of wealth I don't think we will have a problem. Considering that most American tax burdens are far less than the cost of the government services and handouts they consume we only have to head farther in the direction we are inevitable going to make things better. As long as technology can keep up with that pace America should be fine. Robotics can only make socialism better and considering top presidential candidates on both sides are extremely progressive I think Robotics are necessary for our survival.

    I just can't buy this fantasy of the doom and gloom caused by a supply glut due to robotics and insufficient demand caused by the lack of jobs. Our government simply won't allow that.

    The rules are clear, but you have to practically be a pilot to know them. That's because the regulations require you to know what class G airspace is. It's also why commercially you need a pilots certificates to qualify for an exemption. Private pilots are required to know and follow all those same rules without any oversight because they are "hobbiests". That will probably change.

    You know how many times I've seen EEs blow up hardware hooking things up backwards?

    In the software world I see EEs cast datatypes every which way breaking the type safety. EEs that I know just don't understand that people will try to hook things up backwards and they should be protected from it. Compiler protect us when we aren't abusing the type system.

    We mix up type C connectors all the time now, so clearly the type safety is broken. We casted it into a host connector.

  13. Re: What? on Bitcoin Capitalist Opens Bounty For New Block Cipher · · Score: 4, Interesting

    All you need to know if that there is no way for all the machines on the bitcoin network to know when one event happens before another. This is important for financial transactions. The block cipher is a proof of work function which takes some effort to compute. Since this takes a predictable amount of time to compute it can be used to establish a sense of global time and order events. It doesn't always work right away, but eventually if someone tries to double spend a bitcoin one transaction will win out. This establish the trust necessary for bitcoin to work.

    The problem is bitcoin can potentially be manipulated if you get a little bit less than 1/2 of the total network computational capacity.

    I have been looking at the proof of work functions that are memory hard proof of work functions because they are more expensive financially to compute. There are tons of ASICs computing those hashes right now used in bitcoin which are far cheaper than any PC, but memory in an ASIC is always expensive. You get less of an advantage.

    I think momentum proof of work function has potential, but I haven't seen any crypto-currencies use it yet. Let me know if you find one.

    There definitely is a potential for safer currencies than bitcoin

  15. Re:WTF? on New Hack Shrinks Docker Containers (www.iron.io) · · Score: 1

    They are talking about taking a container which is commonly used for implementing the 'cloud' buzzword and using it to implement the 'IoT' buzzword. Someone pointed out that 'things' generally are a lot more resource constrained than servers, so they've slimmed down their 644MB container to 29MB. Good luck fitting that into the 128kB of flash in the typical microcontroller running your consumer electronics.

    It's best not to mix everything together in your head until it all becomes the same thing.

    Containers are great for servers.
    Even if you ran a container on an embedded device, it would need to run Linux.
    That's probably not happening on the microcontroller you describe.

    More importantly theres almost 0 incentive to run Docker on an embedded device simply because theres very few applications which require that kind of isolation on an embedded device.

    About the only device I've seen with a justified reason to use Docker are NAS devices, which are basically mini servers now.

  16. Re:WTF? on New Hack Shrinks Docker Containers (www.iron.io) · · Score: 2

    Even if you know Docker, fewer people actually think about the implications size have on cloud compute systems.

    For example Amazon EC2 Container Registry(ECR) gives 500MB for the free tier and it's relatively cheap to store large container images. Most cloud services store these local registries in their network, so you don't incur bandwidth charges from external registries. Also it should start faster and is likely more reliable, but those are just bonuses.

    It's true that a small image will start faster, but thats usually not a good enough incentive to really sway anyone one way or the other.

    Local bandwidth within a cloud service provider rarely incurs any charges, so really there is little incentive to making it smaller from the bandwidth perspective.

    The problem is that each container takes some memory footprint. Theres usually two ways that footprint size is bad. Some cloud services simply limit the max footprint size that can be deployed. Services like AWS make you manage the AWS instances that will run your container and you get charged AWS instance hours. If you have to start up huge memory instances to run your large containers you will pay more.

    It's all about understanding your computation and memory requirements. Often times your containers are simply sitting their idle doing nothing, but you will always be using the memory, so memory is an important thing to optimize.
