    I liked this one

    "The claim that the lifecycle of an electric car produces more greenhouse gases than an internal combustion car is entirely the result of 50% carefully cherrypicked spin doctoring combined with 50% outright falsehoods. Here's the only way that argument can be made to work. If you buy an electric car with the biggest battery that requires the most manufacturing resources, if you drive your electric car in the least efficient way, if you drive your electric car in the worst climatic conditions for battery life, if you charge it only with electricity generated entirely by oil or coal, if you do not properly recycle the battery at the end of its life, and if you choose for your comparison the biggest-battery electric car against the smallest, lightest, compact internal combustion car: only then will it be true that the lifespan of your electric car generates more greenhouse gases than an internal combu— Oh wait, no; crunching the numbers again, the answer is still no."

    (2) The energy mix of most countries is getting cleaner year over year
    (3) EV would still be cleaner or at leas competitive (assuming it only runs on electricity produced by coal) because peak efficiency of an electric motor is ~95% and that of an engine is 20-35%, so EV are 3-4 times more efficient
    (4) The efficiency curve of electric motors is flat; engines only have a narrow peak. Therefore, ICE car often achieve <10% efficiency in city diving while an EV can achieve 80-90%.
    (5) Even ignoring everything else, cars are where people are, power plants are not.

    In short, whoever came up with the above post is a moron and is paid directly or indirectly by a coal or oil company for his/her selective view (that needs to distort reality on multiple levels to be true).

    sure. try getting a 720p or better stream over the internet without resorting to proprietary and incompatible VNC implementations.
    .. and this is before I bring up encryption or remote user login.
    Try TigerVNC, have been doing this for years

    As I predicted Ubuntu setting Wayland as default is already causing vision research problems: https://github.com/Psychtoolbox-3/Ps...box-3/pull/765

    Hopefully those users use an updated version of PTB when they upgrade to Ubuntu 22.04 if not they'll end up with terrible timing on AMD/Intel.

    No it wasn't, I am using VNC on X11 on many server setups NOW and haven't had any issues.

    With wayland we can now finally move to something modern like RDP or SPICE and perhaps even have remote login. We finally have the tech to catch up with WinXP.

    Coal (lignite) 216.24
    Coal (subbituminous) 214.13
    Diesel fuel and heating oil 163.45
    Gasoline (without ethanol) 155.77
    Propane 138.63
    Natural gas 116.65
    Basically, using gasoline and internal combustion engines is more environmental friendly than EVs and coal plants. And since it's basically established science that gasoline and internal combustion engines are bad for the environment, replacing them with EVs powered by coal that's 50-200% more dirty no matter how you fudge the numbers is clearly not the correct solution.

    Using green vehicles without creating green energy first is like putting a fresh coat of paint over black mold spores. You didn't fix anything; you just hid the problem from view.

This is what I see as an end user. So from this end user perspective, AMD and Intel got it right, Nvidia got it wrong, so therefore this end user will keep buying AMD products in the future, while skipping over the Nvidia stuff.

    95% performance is good enough if it means I do not need to jump through hoops. My time > better gaming performance.
    lol, our company uses Fedora as a default distro for their laptops and they have plenty of issues with Fedora + Wayland trust me (so much so developers who are primarily Linux enthusiasts are going for Mac M1's....)

    And yeah, stock Ubuntu with Wayland has completely broken VNC as I have said before.

    Also not sure what you are going on about wrt screen tearing, no problems on my NVidia machine there.
