Interesting extension. I think I'll give it a try.

It is entirely open source, and the website does a very good job explaining what it does and why.

If you are worried, a qualified medical practitioner is always more reliable than a web forum.

Insufficient or poor quality sleep can cause problems with attention and memory, and can exacerbate existing conditions.

Poor sleep could be caused by a medical condition (sleep apnoea), or psychological (stress). Often stress can be hard to identify, particularly if it's long term stress.

Again, this might not be your problem, and finding the right doctor who actually listens to you is important. Don't be afraid to try more than 1 doctor if the first makes you uncomfortable.

Mint is based on Ubuntu, which is based on Debian. LMDE is being built alongside Linux Mint and is based only on Debian.

Linux Mint and LMDE are functionally the same, but LMDE is protection/insurance against Ubuntu doing something stupid.

It depends on your country, your budget, your definition of good, and your driving needs.

A second hand Nissan Leaf or Chevy Bolt are more affordable, but don't suit everyone's needs.
An MG4 is a great budget new car, but can be out of some people's price range.
A Polestar 2 is a comfortable option from a manufacturer who cares about the environment.
A Porsche Taycan is a performance car for a fraction of the price of a petrol supercar.

I've had a component with +2.4% damage that went to +1.6% when upgraded. I decided to save scum and never upgrade it again.

How would that look with Red/Blue 3D glasses?

You might be right on this one. I'm not able to find a source to dispute that.

In other news, some Chinese car manufacturers are releasing cars with sodium ion batteries late this year / early next year. Lithium might not be a bottleneck for EV production.

I still agree with your initial point. More public transport is needed.

Can you do all 4 at the same time? I genuinely don't know, I haven't had access to windows for years.

I'm a polyathiest. There are many gods I don't believe in.

Avast! runs on Linux.

Personally I prefer to just avoid clicking on dodgy links. In the last 5 years I haven't found any viruses. YMMV

The heat pump uses a 315L tank. The heat pump only runs during the day, so we either have enough solar power to run it, or cheaper electricity at that time.

We have run out of hot water a few times, but with even minimal planning it's not really a problem.

We decided to get a split heat pump and tank (rather than an integrated system) as they tend to be quieter and more efficient. It's barely audible when standing next to it, and provides a great place to sit in summer.

I've just replaced a gas stove with induction. It's far better than the gas stove was and I never want to go back.

Also replaced the gas water heater with a heat pump. The gas bill went way down, and the electricity bill didn't go up.
