Saying RAM can help because you can reencode the video to h.264 or h.265 to make use of hardware decoding is more than a bit of a stretch. You can just reencode it to the normal disk instead. Unless it's the speed of the local block device that's the bottleneck here (and there's no indication that it is, and it would be extremely unlikely), using a ramdisk/tmpfs for any part of that is just pointless.
Modern CPUs (from like the last 20 years) will throttle down a lot before they actually shut down. Unless your cooling is completely inadequate or somehow broken, shutdowns because of high load just dont happen. I suspect there is something fundamentally wrong with your hardware.
A problem with cooling could also go some way to explaining your performance problems – but it could also just be that your system just doesn't have the computing power to do what you want it to. The computing demands from video decoding go up dramatically when you go beyond 1080p. If I recall correctly, the Intel Core CPUs with the "U" at the end were the low-energy models (for longer battery life); of course that comes with compromises on the performance side.
The CPU model suggests that this is a laptop, and a fairly old one at that. I would look for things like blocked air ducts or broken fans if I were you. It's also possible that the thermal compound between your CPU and the CPU cooler has dried out and needs replacing (although laptops of that power class should be using thermal contact solutions that do not dry out), or that contact has lessened for other reasons. Again, if your computer seriously powers down because of load, it's borderline broken and in need of maintenance.
As for your other question, no RAM cannot help with that. It can hurt if you have too little of it, but once you have enough, the best it can do is not be a bottleneck.
Edit: Also, make sure you are not setting down the laptop on anything soft, like a blanket, when using it. It will sink in and have its air intakes blocked if you do that.
We're getting close to the point where "running a stock ROM" is on the same level of inadvisable as "using a web browser without ad blocking". The latter of which was, btw, also not that big if a deal like ten or fifteen years ago.
This woman could probably afford to just buy a new house if her current one is in need of a new coat of paint, let alone if it's suffering from mold growth. Yet she chooses to live like this.
Also, I cannot get over that look on her face. That sheer barely hidden contempt oozing from it. The superiority complex behind it. The signature look of a narcissist.
Varta is that company that maneuvered to kick out all small scale investors without compensation and hand the company over to only the big investors. The fact that this maneuver can possibly be legal is a major problem for the German and EU industry.
Key elements manufactured in Spain include the Battery Management System (BMS) electronics and proprietary software, plastic and metal structural components, wiring harnesses, and the cooling system. Active and passive safety devices, power connectors, power supplies, busbars, and user interface electronics are sourced from other European suppliers.
So just about everything except for the actual battery cells.
Don't get me wrong, having the stuff made in the EU is better than nothing. But the real challenge is still the actual cells. The stuff they do produce is relatively trivial (on an industry scale) and could be spun up on short notice if needed.
I haven't seen a real landline in a very long time. All the supposed "landline" connections in people's homes just turn out to be VoIP connections terminating in their internet router and masquerading as a traditional telephone landline.
Hm, agree in principle, but it should also really be noted that a donation that is required to get an account (or arguably even smaller perks) does not count as a donation anymore. At that point, it's a weasel-wordiy way to say "payment". Which should, IMHO, not be supported.
Sure, unless you do all those things that make nuclear energy (mostly) safe, in which case it will beamong the more expensive options for electricity again. Also, just transferring the electricity via the grid to your home will cost many times that, regardless of the energy source.
The only context in which I've ever heard of that place is that big military cemetery.
