One thing I liked (and sometimes disliked) about Reddit was that my feed was a mix of posts in communities I'd joined and a few suggestions of posts from subs The Algorithm™ thought I might like.

On Lemmy I'm realizing I'm starting to fall into a bit of an echo chamber situation because I basically only see stuff I'm already a member of, unless I explicitly go to All or scroll the list of communities.

Are there less involved (lazy) ways of discovering new stuff and broadening my horizons a bit?

Sometimes, when I'm really cold, it can take over an hour to warm me up, even with a heating blanket. The quickest solution, a hot shower, feels really inefficient with all the heat going down the drain.

That got me thinking about microwaves. They heat food (partly) from the inside, contrary to simple infrared radiation.

Could we safely do that with people?

I found a Reddit thread where a non-lethal weapon and people getting eye damage because they stayed too long in front of a radar dish.

Could some sort of device be made that would warm specific areas (say, a hand or a leg) without endangering sensitive areas like the eyes?

Would it actually warm someone up from the inside? Would it be possible to make it safe?

Would it present advantages in cases of hypothermia, compared to heated IV fluids?

I don't see how it's a benefit to capitalism or companies or, well, anyone, really, to allow people to make thousands of trades a day for minute profits on each.

My gut feeling is that the stock market would not suffer, and less resources would be wasted, if trades and updates to stock prices were limited to, say, one batch per hour.

There are probably reasons the system is the way it is though.
