  • please explain how to transfer bitcoin without mining a block, since the transactions are contained there.

    You need to take the energy required to mine a block and validate it (a lot, could power a small town), then divide for the few transactions that could be included in just 1 mb.

    They impose a size limit on the transactions that can be included, so even if tomorrow the transactions increase 10x, each block could contain the same limited number. Of course, if you only count the electricity used by your machine to send the transaction, it’s just a few milliwatts. The problem is all the garbage calculations that need to be done to actually validate it.
















  • Generally good at supporting phones but not at supporting computers, a 5-6 years lifetime is unacceptable from an environmental point of view.

    I experienced it last week when I turned on an old Mac with MacOS 10.7. It can’t run anything. Everything that you download doesn’t run anymore, Firefox and chrome are limited to some ancient version like 40 that breaks every modern website and due to some expired SSL root certificate you can’t access any website that’s using let’s encrypt which is a big chunk.

    And it’s like this not from recently but at least 5 years, so it was put in a corner and never turned on anymore until last week

    It can theoretically be updated to some newer version but the updater to 10.8 has been delisted from the store so you have to alternatively source that.

    For comparison, a PC that was purchased the year prior to that Mac is running the latest version of windows 10 without any issue (except slowness due to the 1st gen core architecture)








  • And not even enough. As a society we’re condoning too much when it’s about cars.

    Going 100 in a 30 should be charged as “attempted massacre” if stopped. Because it’s not an “accident” anymore when you go that fast.

    And driving that fast in a residential area without being under the influence of drugs or alcohol, should be an aggravating circumstance and not the opposite.
