Maybe they mean X11-screens. That are more or less independent screens, you can't move a window from one to the other for example.Emacs supports that somewhat with the "open new frame on display server" menu option, but usually, multiple screens are not very useful.

Nowadays, multiple monitors present one big virtual framebuffer and only one logical X11 screen.

Not an expert, but AFAIK 450 is a non-permanent error that basically says "try again later".

They claim not only fast charging, long life and low cost, but also very high energy density, no degradation in low temperature, no thermal runaway, non-hazardous materials and no "geopolitical" needed.

I think it is safe to assume, given the buzz all around the donut battery, that VTT would immediately release a statement if this report was fake.

It would probably make more sense to target something like this https://www.hackster.io/news/andrew-bunnie-huang-prepares-th... with linux, has MMU and more RAM.

Interesting. I sometimes get similar behaviour on KDE / wayland, usually it is "2" or "3", and it seems to only affect electron apps. Always thought it has something to do with a dodgy ps/2 to usb converter I use to attach my old mechanical keyboards. I think it does not happen if electron apps are started with "--ozone-platform=wayland" but not completely sure, and I have no reliable way to reproduce or somehow trigger that behaviour.

Aren't they talking about the c++ dialect the compiler expects without any further -std=... arguments? How does that affect the bootstrapping process? This https://gcc.gnu.org/codingconventions.html should define what C/C++ standard is acceptable in the GCC.

The BMW i3 was an interesting car, it's a pity they cancelled it and don't offer it with current drive train / battery. There are 3rd party battery upgrades available though if you get a used one.

IIRC there were BMW i3, Nissan Leaf (2010) and later Renault Zoe.

BMW in cooperation with Toyota has/had H2 cars (currently iX5), but it is some sort of pilot phase.

Tesla with their model 3 and supercharger network demonstrated that electric vehicles indeed are viable, and that got the ball rolling.

I agree that a small / compact car is missing in the Tesla line-up and that also hurts their european performance (and will continue to hurt).

Nobody is constantly charging their completely empty EV.

A typical commute of 50km/day at 20kWh/100km means you have to put 10kWh into you car (per day). A 230V outlet can deliver 3,7kW at 16A, so your car would be topped up again after about 3h.

Tesla Supercharger prizes at 20kWh/100km are in the same ball park as Diesel at 5l/100km. Charging at home should approach half that, and charging with PV will amount to <2€/100km.

We don't want the CO2 that is created (and other consequences of oil production/consumption), the money can be spent on something better, and we don't want to depend on oil-exporting countries more than necessary.

You also get rid of brake dust (for the most part).

This study https://www.oecd.org/content/dam/oecd/en/publications/report... (page 95) sees nowhere near 5 fold increase of particles from tire wear with EVs, for lightweight EVs you get a significant reduction in overall particle emissions.

Individual owners may care about brand toxicity or may not, but it affects how much tesla can charge for new vehicles and resale value of used ones. Of course this analysis is just MHO, maybe the real cause why EV market is expanding and Tesla is stagnating is something completely different, like missing "android auto" resp. apple equivalent thing functionality.

Tesla Model 3 is typical middle class sedan size IMHO, like VW Passat, Audi A4, BWM 3, i.e. one size up from VW Golf/Tiguan/Touran.

Tesla was different because it was no gas-guzzling V8 behemoth that takes at least 20l/100km like what you used to associate with "US cars".

Europe is not the US, we have somewhat functional public transport in most parts of the continent, you are not _that_ dependent on a car. Also, EVs will become cheaper than ICEs, with or without subsidies or tax incentives, it's only a matter of time. Battery prices on a cell level approach €40/kWh. A new drive-train incl. battery will be < 2000€.

Also, given that polluted air affects poor people the most, getting rid of all that exhaust of old worn out cars with ICEs will be a good thing in any case.

US made cars had the reputation of being low quality, too big, too heavy and too inefficient for european cities.

Tesla was somewhat different. People bought Teslas not for their promised "self driving" capabilities (I know no Tesla driver that took those promises at face value or got the FSD option FWIW), but one motivation was to "stick it" to snobbish arrogant european manufacturers wanting to develop "clean" ICEs with "green fuels" or other non-sensical crimes against thermodynamics like H2-cars.

Now, Tesla (and the US in general) has a brand toxicity problem, and it is worsening. People I know that would consider a Tesla some years ago now drive electric VWs or BWMs or KIAs, often times much more expensive cars than the comparable Tesla 3 / Y model.

This trend will probably continue the next years, and I don't see a way for Tesla to repair the brand image.
