    It's a bit long for a one-liner, but this should work.

    for f in /media/johann/5461-000B/DCIM/100MEDIA/*.AVI; do num=${f%.AVI}; num=${num##*IMAG}; ffmpeg -i "$f" -ss 00:00:00 -t 00:00:20 "~/Public/240321/240321_$num.avi"; rm "$f"; done

    This num=${f%.AVI}; num=${num##*IMAG}; extracts the number from the video filename. To make sure it's not deleting anything it shouldn't, you also might want to run it with rm -i "$f"

    It's insane.

    The thermodynamic minimum amount of energy needed to extract CO2 at 450 ppm is 120 kWh per tonne. Current experimental carbon capture plants run at about 5 % efficiency. If we assume we can double their efficiency and can magically produce as many plants as we need, to remove 20 Gt of CO2 per year (half our emissions) we would need 24,000 TWh of energy per year.

    That is the entirety of the world's electricity production. To remove half our emissions.

    Carbon capture is a non-runner.

    My entire life has vim key bindings. My window manager and browser all have vim key bindings. I work in vim. I write my shopping lists in vim.

    I really can't overstate how ingrained vim is in my day to day life. Bram had a big impact.

    Bram Moolenaar, creator of vim, has died. If you are a vim user, consider donating to *International Child Care Fund Holland* - a charity Bram heavily supported. You can find the link on [vim.org](https://www.vim.org) :wq

    Emissions are no longer following the worst case scenario

    While the title of their article is correct, it's not exactly the full story. Human emissions as accounted for by the Global Carbon Project have leveled off but atmospheric CO2 and CH4 are still rising. (And in CH4's case, accelerating rapidly)

    Atmospheric CO2 vs. RCP

    Atmospheric CH4 vs. RCP

    While the leveling off is a big improvement, we are a very, very long way from fixing this and feedbacks are kicking in that may well make it impossible.

    And just for reference, here are the RCPs out to 2100:

    RCPs - CO2

    RCPs - CH4

    If you're interested, you can get RCPs here and observations from NOAA.

    The RedReader developer (QuantumBadger) said they'd like to make it a more general reader app and include support for RSS and Lemmy. It would take a while to to it though. They would have to abstract a lot of the Reddit specific code.

    I hope they do it, it's a really nice app.
