The worst searches I have encountered are Thunderbird and Discord. While Google is the gold standard, there's a whole range between the former two and the latter. Just fuzzy search goes a long way, but it seems Thunderbird and Discord

Great read on Jupyter Notebooks. I've always had a strong dislike for them as well - just feel fuzzy, dirty, often in weird state - and the user put it into words nicely. I might just be bad with Jupyter, but I've been willing to

TST does look great. Not sure it's usable in my case: - similar to what others mentioned, I'm running a browser at 50% width of fullscreen (27", 4K display). This is ideal for most websites: it's about as narrow as most

I actually prefer having as many different colors as possible. A class definition is orange, functions are pink, strings are green, ... (Material theme). It's just very clear at a glance. If everything's a subtle shade of one colo

I would argue in conjunction with zfs snapshots (can be every minute), it's safe and the caveat no longer applies.

Maybe this is good enough for your use case: https://dangerzone.rocks/ It converts documents to just images, then converts those back to PDF, all in a sandbox.

There are fundamental thermodynamical limits to certain processes involving energy transfer, conversion etc. Heat transfer comes to mind. Those cannot be engineered away. For simple mechanical systems, yes, inefficiencies can be removed, bu

I had trouble believing that (astronomic scales always seem so much more vast), but it checks out (SI units): p = 1e5 l = 38.6e9 * 1.61 A = 0.27871 R_m = 8.3141 M_CO2 = 12 + 16 * 2 R = R_m / (M_CO2 / 1000

That's true but assumes the captured CO2 remains that, captured. The article revolves around the idea of turning CO2 into fuel . Fuel which is burned, releasing that same CO2 again while having wasted a lot of intermediate energy. At

And what do you get by replacing one ICE vehicle in Europe with an electric one? You get two cars. A shiny new electric one running in (Central) Europe, and that same old stinky ICE one running in Eastern Europe, Asia or Africa. The poore

It's even worse than zero net effect, it's negative, owed to all the auxiliary inefficiencies. Add to that methane slip and it's infeasible by a long shot. The solution can never be to remedy surface-level GHG. The sources ne

I'm doubtful 7h of sleep a night and 1 drink a day can render a given individual more mentally able. I'd guess the causation is that the cognitively most able people just happened to average on these values. I sleep 8 to 9h a day

I don't know why you are being downvoted. You are correct, and some ICEs (large, maritime) are hitting 50% even. For a thermal engine , that's incredibly good (it's not about the gap to 100%, but the gap to Carnot efficiency

Large scale, yes, I'd say so.

Not wrong! However: - batteries: not available large-scale - thermal storage: potentially terribly inefficient (but as I said, yes it's at least something!) - pumped hydroelectric: where I'm from, only available to a tiny fraction

NOx (and PM) is a local, temporary consequence. Catalysts exist to remove NOx out of exhaust gasses. They are perfectly serviceable. Carbon dioxide is a permanent, global issue, where no (large-scale) capturing/cleaning methods exist.

You're comparing apples and oranges. The around 40% efficiency modern ICEs have is thermal . The 90%+ going from battery to electric motor is not thermal. You're just converting high-exergy to high-exergy (kinetic) at that point.

Efficiency is not a huge concern when highly fluctuating energy from renewable sources is involved. You either have zero efficiency because it goes to waste for lack of storage, or some efficiency through hydrogen (electrolysis).
