About kalessin

kalessin, aka, Louis Opter.

I used to work at dotCloud (which pivoted to Docker in 2013), before working at Uber until May 2018.

    Not a lot is inaccurate given the carbon intensity of coal and its importance in Germany's energy mix. Anyway, I think the nuclear debate is quite off-topic here.

    Thanks I hate it, extremely noisy and dirty. I really wish the brand dies with fossil fuels.

    Weird, my experience has been that EVs are much quieter and that's a real improvement in densely populated areas. Past a certain speed the main source of noise is the tires and the…

    The correct unit is GW.

    Absolutely, and that's different than saying « they don't really require ongoing fuel shipments ».

    When you consider the intermittency of renewables, and you should, fuel suddenly becomes an issue again.

    I like the idea of "cognitive debt" vs "technical debt".

    Why? I am not sure photosynthesis plays a large role in the lower carbon footprint.

    Apple’s support for MacOS can been shorter than their laptops longevity (the longevity of their laptops got quite bad when then tried to make them as thin as an usb-c port). So Lin…

    I don't want to fix it myself either, and I don't see how a repair industry could exist without the right to repair.

    I don't really understand the idea of micro-grids, how do you account for redundancy, or long term storage if inclement weather goes on for a few days? Do you just keep big fossil …

    Seasonal storage for what kind of usage? FYI, we have clean, and proven, energy sources in our toolbox that are not intermittent.

    FLA3 is a first of a kind and is a bad example. Nuclear is working very well for France at the moment, we are back to high-availability and making a lot of money through exports.

    There is bridges between military and civilian nuclear, however keep in mind that nuclear reactors like the EPRs being built in the UK are designed such that producing the necessar…

    It was a partial meltdown in a pressurized water reactor, it cannot be compared to Chernobyl, it's a completely different technology. PWRs can't explode like what happened in Chern…

    I strongly recommend split hands, ortholinear layout and thumb clusters too, as well as a programmable firmware so you can setup your own layers.

    It is important to note that the gas exported to China and Europe are exported from different fields, and are not connected with each other. As it stands right now, Russia cannot e…

    There is still hope, but we sure do need a global mindset shift when it comes to nuclear (and many other topics for sure). Global warming will make parts of the worlds inhabitable.…

    Fusion is multiple decades ahead of us still, even with more funding, but we need to take action this decade if we want to have an impact on global warming. Fusion is unfortunately…

    That's not the case at all, nuclear should be how we replace coal. Nuclear is one of the safest way to produce energy today, including the Chernobyl & Fukushima incidents. Nuclear,…
