the problem is more often in some specific chips that burn all the time (USB-C, battery controller), are rather cheap, and are un-available because Apple (and others) forbid the manufacturer to sell those separately. there are plenty of vid

Thanks for the links! I unfortunately have very little time for learning new tools but very insightful article! I am sure you're trying to make friends in the rust community with the "on error resume next" thing!

looks great on paper, managed to get the aarch64 version of Ubuntu server running on M1 but the intel version crashed somewhere in the install.

This piece is fantastic and makes me want to learn Rust !

yes, this is something most ppl get wrong.

agreed, 1.1 GW seems reasonable for GVA. thanks!

I agree it was overestimated, note to self: always redo ppl's maths. 1) number of barrels of jet fuel per day in switzerland: 34000 barrel / day = 0.39 barrel / s https://www.indexmundi.com/energy/?produc

Are you aware that tritium like hydrogen is very hard to contain as it's as small as hydrogen and very nasty as it's highly radioactive. That alone prevents this technology to become cheap any time soon (assuming they get Q>1).

yes! rail is amazing in term of efficiency, a common high speed train has around a credit card worth of contact area with the rail for the whole train! it's also quite relaxing and socially interesting. the problem is that rail is &quo

there's none. and (unfortunately for me) the best solutions often involve less technology rather than more.

let's assume we can scale renewables+nuclear fast enough so that our civilisation is not damaged too much by climate change. let's also assume we stabilised biodiversity and avoided a mass extinction. should we continue to produce

yeah and there's crop failure coming decades in advance compared to IPCC's predictions, so better not using crop space.

I wish that the 3 law of thermodynamics laws were more commonly taught... because here you are battling the 2nd and the 1st. A calculation by Jean Marc Jancovici showed that for a small airport (GVA in this case) you'd need half a doze

yes and no. physical theories always have a domain of validity where their prediction make sense and QFT and QM do not give an absolute value of energy (density). sure you can do QFT on curved spacetime (Hawking had some success w/ i

for C++ folks i can only recommend pybind11 which provides a numpy interface. it's a breeze to use, header only.

i'll add to the other comments that usually in theoretical physics we often build lagrangians directly from the symmetries: if you only have terms that are dot products then the lagrangian is invariant under rotations and angular momen

Very neat! unfortunate it doesn't use LANC, i would have built one for my BMPCC original.

1.1 degree above pre-industrial reference and it is already a nightmare and yet we drill again to keep the carbon economy running. not a climatologist (just an interested physicist) but (some of) these heatwaves overshoot models predictions

As a physicist i would be glad you explain me your reasoning a bit further, for instance how the droughts is independent from climate. You look very knowledgeable.

i suggest you go explain your opinion to poor countries experiencing climate related crop failure and famine this year. i'd also suggest you inform yourself with the relevant literature, IPCC's AR6 is a good start.
