    Or you use a heat pump and get more heat for the same amount of electricity.

    Good point.. But there are some situations where a heat-pump would not be viable, like possibly a water-heater or stove... Or as a dump-load for solar/wind etc.

    No it does not take less electricity to mine if there are fewer miners. It takes EXACTLY the same amount of electricity. the ratio of the mining cost to the rewards would be the same evenif there was one miner.

    Eh what?
    1 miner doing mining with a 500W (1Mh/s) machine. Network adjust difficultly to allow for 1 block mined every 10 minutes.. total mining power is 500W and will result in 1 block every 10 minutes... Ie 6 blocks per hour for 500W..
    100 miners doing mining with 500W (1Mh/s) machines.. Network adjust difficultly to allow for 1 block every 10 minutes.. Total mining power is 50KW and will result in 1 block every 10 minutes..

    It does take a bit of time for the network to adjust difficulty, but it slowly (adjustments made every 2000-ish blocks) adjust the difficulty to allow for 1 block every 10 minutes for the whole network.

    So lets say we allow for the network to adjust to each of these situations.
    Total of 1 miner would mine 12.50*6 (=75) bitcoins in one hour at a cost of 0.5KW. (6.6Wh per bitcoin)
    Total of 100 miners would mine 12.5*6 (=75) bitcoins in one our at a cost of 50KW. (666Wh per bitcoin)

    Reducing emissions of any kind is a good thing... How to implement it in a good way is a different story..

    Stop feeding cows corn and soy-based feed to start with and that will reduce their emissions a crap-load. (yea, i had to go there :)

    Providing economic incentives for companies that produce goods at lower emission-levels will result in lower emissions and will start a race to produce the most amount of goods with the smallest environmental impact. How to do this on a global market can definitely be tricky, but should be doable with import-taxes or other emission-requirements for imported goods.

    And what happens if you get less miners? Well the difficultly drops so it requires less electricity to mine there by making it profitable again to mine..

    Fees by themselves are there to allow miners to make a bit extra.. The miners will pick the transactions with the highest fees first and include in the blocks, so if there are loads of unconfirmed transactions people will choose to pay a higher fee to have their transactions complete faster. But even then, when we had the issue with loads of unconfirmed transactions i still could make payments with low fees, but they took forever before being included (confirmed) in a block.

    If you look far into the future, when all payable blocks have been mined, it will only be transaction-fees that will pay for the miners.

    If bitcoin will survive i think we will have bitcoin-miners in everything where we have a need to generate heat from electricity. Why push electricity thru a resistor to generate heat when we can have a
      CPU/ASIC/FPGA/whatever using the same amount of electricity to do bitcoin-calculations and still generate the same amount of heat, with the benefit of collecting some transaction-fees. Of course the miners will have to drop down quite a bit in price for that to happen.

    What both Canonical and Mozilla failed at was to get their respective OS'es attractive for consumers.. There where a number of devices launched, but they all failed to get any market-share so they where both canceled when they realized that.

    This device does have a niche market that may attract security-minded people.. Bringing a device like this to market in 2 years is fairly simple, depending on what SW you aim to run on it. In the video presentation they speak about running basically any linux-distro on it, so my guess is that it will just be a tiny portable PC with 3G/LTE capabilities.
    Question is what type of app's will be available on it, in addition to what you can install from the distribution repos..

    That's how i see it anyway..

  17. My guess is that thorium reactors are the closest to made commercially possible. Safe in terms of the nuclear reaction since they cannot melt down or have their pressure-vessel explode... Would produce less waste. Can be used to consume the existing spent fuel-rods reducing the amount of waste we have. Will produce things that are highly radioactive, but so radioactive that we only have to store it for a few hundred years. (The more radioactive something is the faster it decays) Does have some technical issues, but not unsolvable, before it could be widely deployed.

    Fore other types of reactors have a look at http://nuclearinfo.net/Nuclear... under the section "The Fourth Generation Reactors".

    From the above link above:

    The Fourth Generation Reactors
    In 2002 the Gen iV Internation Forum (GIF) nations (Argentina, Brazil, Canada, France, Japan, Korea, South Africa, Switzerland, Russia, United Kingdom and the United States of America) proposed a long term research and developement program to investigate 6 promising new reactor designs.
    The six design concepts are:
    The Gas-Cooled Fast Reactor (GFR)
    Very-High-Temperature Reactor (VHTR)
    Supercritical-Water-Cooled Reactor (SCWR)
    Sodium-Cooled Fast Reactor (SFR)
    Lead-Cooled Fast Reactor (LFR)
    Molten Salt Reactor (MSR)

    These reactor concepts are designed to address the energy needs of the World into the far future (post 21st century).
    They efficiently utilize Uranium (many can employ depleted Uranium or "spent" fuel from current reactors).
    Destroy a large fraction of nuclear waste from current reactors via transmutation.
    Generate Hydrogen for transportation and other non-electric energy needs.
    Be inherently safe and easy to operate.
    Provide inherent resistance to Nuclear Weapons proliferation.
    Provide a clear cost advantage over other forms of energy generation.
    Carry a financial risk no greater than other forms of energy generation.

    To kill someone is to cause physical harm... Not acceptable..
    If i say something they can choose to ignore me or they can choose to argue with me and try to convince me that their ideas are better..

    As long as i don't cause harm to a person or property i should be free to do what i want. And no, i do not consider your feelings being hurt to be harm to a person.

    If i slander then that can cause harm (financial or reputation) to a person.
    If i say "I do not like X" then who does that harm?
    If i say "Y is happening" and Y is false i would be liable for any harm that may cause.. If it's about a immediate danger then people cannot reflect on it and act on impulse.. If it's not about an immediate danger then people can reflect on what i said and choose or not choose to believe me.

  19. Would that not be classified as hearsay?

  20. What about if a person forgets the PIN/Passphrase or remembers it incorrectly?
    What if they enter the wrong PIN/Passphrase too many times, in an attempt of testing the provided PIN/passphrases, causing the device to erase the encryption key permanently?

    Who would the burden of proof be on in those cases?

    Not sure about you, but i know of people that easily forgets Passwords/PIN-codes unless they use them daily. What is the time between seizing the phone until discovery starts? A couple of months? A year? What does the stress of being put in jail do to your memory?

    Some questions for you:
    - Would it be classified as destruction of evidence if you forgot your PIN and did not write it down? If you write down a PIN that could be seized with a warrant making everything on the device available and not only the documents specified in the discovery.
    - Should forgetfulness be considered a crime? (Failing to remember PIN, Failing to remember to write down PIN on a paper etc)
    - If you fail to provide, whatever the reason, the PIN in a murder-case should that be punished on the same level as the actual murder?
    - If you provide a PIN you verify that the device is yours, and performing that action could then be classified as evidence.
    - If you have a multi-user devices (like android supports) and if you only have the PIN for one of the users and you are being forced to provide the PIN for the second user.. How should that be handled? (Same goes if you have a application that does a second layer of encryption where you may or may not remember, or have access to, the PIN/Passphrase)

    There are so many things that are problematic in terms of punishing people for failing to provide a passphrase/PIN to unlock/decrypt something..
    Fine, if they can prove you know the PIN that would be a whole different story, but proving you remember something can be quite hard unless you proved that you unlocked the device just a few minutes ago and you have not been put into any stressful situation between then and now, and provided that just asking the question for the PIN may be stressful to some.
