From my perspective, these ultra high speed charging solutions are not the right way forward. We definitely won't manage to upgrade our grids in a way that such insane charging speeds are possible for the masses. You might have some very few high speed chargers for niche use cases but there's simply not enough energy production / storage capabilities to allow for that for a bigger number of people.

Energy providers are investing lots of money to make their grids smarter and reduce peaks in production and consumption. Spontaneously adding or removing a load of 1.6 megawatts is exactly the opposite and would be only for one (!!!) single charging port. If we wanted to install 50 of these chargers we are talking about 80 MW which already needs a small power plant on its own.

We should find solutions to allow slow charging as often as possible while minimizing inconvenience. I.e. charging while sleeping, at work, while shopping, when doing sports etc.

Fast charging should be used only for long distance travel and also there we should limit it to a reasonable speed. And from my perspective the current cars (150 kW+) are completely fine already also If that involves a small (!!!) break every 400 km or so.

Nah. Also in Germany styrofoam is used for take away by some places. But it really sucks from my perspective. If you put really hot stuff in it (like fries straight from the fryer) it may melt and your fries have plastic shit attached to them and, since it doesn't allow condensate to exit the crispy food will turn soggy really fast. Carton is so much better from every perspective.

Luckily, legislation in the EU is trying to reduce single use plastics.

Cool, that's great! :)

Maybe they also allow to rebind the switch to another function later. At least in custom ROMs that should be possible.

I discovered FitoTrack via Lemmy a couple of months ago and am really satisfied. No issues at all.

Okay, that's strange. When you say workstations, I assume that you had pretty decent hardware and probably more powerful than my consumer notebook. I usually don't notice lags or load times > 1 second. If I do a complex operation like mass-cloning an object via a polar pattern, I have to wait for 2 or 3 seconds but really nothing that bothered me in the workflow. Definitely never anything close to a minute as you described.

If you want to give FreeCAD another chance one day and still experience the same issues, maybe bring it up in the official forums. The experts there might have an idea what could be wrong.

I never had these kind of performance issues at all. I use it on three different ThinkPads, all not too bad but also no crazy hardware. The cheapest should be an E14 with a AMD 5500U and 16 GB of RAM that was around 500€ 4 years ago.

Isn't Fusion360 cloud-based? If so, it doesn't make too much sense to compare the performance on a certain hardware.

I currently switch a lot between FreeCAD and Sims. When I brainstorm with my girlfriend we either use a simple drawing programm or Sims. Then, once we aligned on an idea, I use FreeCAD to bring in accuracy. Quite often then the original ideas don't work out because of wall thickness, window placement etc.

I currently combine Draft, Bim and Sketcher to plan my house. You can also use Tech Draw and Part Design in some areas. I think FreeCAD has a steep learning curve with all the features it has, but it's also incredibly powerful.

If you want to do accurate calculations, wall thickness, exact angles, window sizes etc., I would recommend FreeCAD, especially the draft workbench and possibly the BIM workbench if you want to go 3D afterwards.

If you are more looking for a rough planning where you can test furniture placements, floor designs and see fast results, I recommend The Sims 4 (no joke!). The base game is free (also available on Steam) and it's quite easy and intuitive to move stuff around, change a wall, place decorations etc.

The draft workbench and sketcher workbench in FreeCAD are both only for 2D projects.
