If you see sparks and smoke coming from the computer, you can be pretty sure you’re doing something wrong.

In Nordic folklore, there’s a concept for a household spirit (nisse/tomte) that may do mischievous tricks if you don’t treat it appropriately. If mathematics can’t solve this puzzle, it has to be a computer tomte that isn’t happy with your taste in RGB or how infrequently you run software updates.
- Comment on The Amount of Electricity Generated From Solar Is Suddenly Unbelievable 3 days ago:
First commercial heat batteries have already been built. Hopefully, the technology will become more widespread, as heat is such a nice form of energy. My guess is, it’s mostly a political and financial problem at this point.
Storing energy in other forms is a lot trickier, but at least there’s no shortage of potential technologies to try. It’s just that most of them tend to be in lab or pilot scale at the moment. That Chinese RFB facility was a notable exception though.

China is already on it.

That’s a mathematics problem. Current theory of probability doesn’t account for cases where the probabilities are actively fighting against you. Once you’ve formulated the axioms of antagonistic conditional probability, you should be able to understand how USB-A ports work.

Next, we’ll try the petroleum refinery method. First, let’s get some steel pipe, a MIG-welder and a barrel of crude oil.

And not just a little bit either. Seems like he really really hates everyone now that he returned to this topic.

You could also technically fix it using the “missing Missy” method.

- Comment on Which instance should i choose when i share a link? 2 weeks ago:
IMO link B is the “most original” one. Sort of like an “authoritative source”, if you will.

Imagine what it’s like to calibrate an instrument like that.
- Comment on xkcd #3106: Farads 3 weeks ago:
But why pick one pound? The are so many fun units to choose from, only some of which are conveniently sized. How about a stick 1 mile long, or a rock that weights 1 grain?
- Comment on Batteries are so cheap now, solar power doesn’t sleep 3 weeks ago:
Latitude and clouds really matter in these calculations. Further up north, the light gets weaker, so you’ll need to compensate with more panels. Also, the sunny hours fluctuate wildly between the short days in winter and short nights in summer.
The closer to the equator you are, the more sense it makes to use solar power. In places like Germany, it’s already fine, in Greece it’s really good. Anywhere south of that, it’s clearly the best solution.
- Comment on Finland warms up the world’s largest sand battery, and the economics look appealing 4 weeks ago:
Conversions tend to be inefficient, but in this case you can use only the best kinds of conversions.
They’ll use cheap electricity to heat up the sand, which is approximately 100% efficient. Then, the heat is stored for a while, and that’s when some of it will leak through the walls. Not a whole lot though, because of insulation and a small surface to volume ratio. Eventually, the heat is used to heat up water, which is another highly efficient conversion.
If you convert another form of energy back to electricity, you tend to lose a lot of it as heat. Physics just loves to use heat as the final destination for all sorts of energies, so it only makes sense to aim for making it instead or treating it as a byproduct.

An atmosphere confirmed to contain atoms? As opposed to plasma or neutron pasta? Yeah, I guess that counts as an improvement.

This should cover it fairly well.
- Comment on xkcd #3097: Bridge Types 1 month ago:
You forgot the trivial case, of not building a bridge at all. Just go around the gap.

I don’t know about you, but I’ve been #Bloomscrolling lately. As far as I’m concerned, the MAUs are here for the wows.
- Comment on Fediverse Social Media Guide 1 month ago:
Risky comment of the day. Maybe they just don’t like to hear what I have to say. Maybe I could have been a little less blunt about it. Who knows. ¯\(ツ)/¯.
- Comment on Fediverse Social Media Guide 1 month ago:
Both extremes exist. Hence, the condition about loosing your grip on reality.
- Comment on Fediverse Social Media Guide 1 month ago:
People above a certain age should begin to avoid all social media and stick with more private forms of communication like email, phone calls, signal messages and f2f discussions. Once your ability to tell fact from fiction deteriorates enough, announcing your opinions publicly becomes increasingly problematic.
- Comment on This graph but with fediverse apps? 1 month ago:
Interesting. That exact same logo was used by the app that changed its name to Impressia. So, maybe it started as one thing, but later evolved to what it is now. A confusing journey really.

Air just gets in the way, in more than one way actually.

- Comment on This graph but with fediverse apps? 1 month ago:
Isn’t that just a pixelfed app? I think Vernissage changed its name recently. Nowadays it’s like Impressia or something like that.

What about the Marxist-Leninist, communist, socialist, anti-capitalist crowd? I don’t know if they hang around on other platforms, but they certainly are present here on Lemmy.
Also, what about sexual and gender minorities? I get the feeling that there are a lot of queer people on Mastodon. Maybe that could be another selection criteria.
Like this:
Are you queer? -> Mastodon
Are you a Marxist? -> Lemmy

If you can’t jump high enough, we can always give you a little boost using a high-energy electron beam from the synchrotron. Either that or the high-power UV laser. Up to you really.

To make it a bit easier to measure the difference, you could do this in free fall or micro gravity environment.
- Comment on Yes, Social Media Might Be Making Kids Depressed: Depression symptoms jumped 35% as kids’ average social media use rose from seven to 73 minutes daily over a three-year period. 1 month ago:
As social media isn’t going anywhere, the user needs to bear the responsibility of controlling their own feed. For example, you could subscribe to !lemmybewholesome@lemmy.world and follow #bloomscrolling on Pixelfed. The internet just loves to give you anything and everything, so it’s up to you to pick and choose.
- Comment on Usernames using randomized nonsense 2 months ago:
Also, some people will intentionally add numbers at the end of the alias to make it look like all the good names were already taken. Sort of like a joke or a reference to all the bigger social media platforms.
