Oh. That’s a new one for me.

Had to look at my keyboard to translate that.

If you’re only live threateningly injured doing analysis, but die 5 minutes later, it counts as a win.

Also, it speaks of it as renewable energy, even though it’s clearly not. Producing hydrogen this way consumes elemental iron, which will eventually run out. When there’s nothing but rust left, the reaction will stop and your lovely “renewable” hydrogen mine will will stop producing hydrogen. If we call that renewable, then uranium is renewable too.
Well, at least it produces energy without any direct CO2 emissions, so that’s a clear benefit.

Do people actually use the same name on every platform? I know I did, until I realized I specifically wanted to avoid people from connecting the dots.

Yes, the wings are a huge problem. Not that many roads can handle something as wide as a plane.
- Comment on xkcd #3124: Grounded 3 weeks ago:
You know, those jet engines are LOUD. Sure, they can technically move the plane on regular roads too, but the noise is just astounding.
In a big airport you might not have noticed, because you were either in the terminal or in side a plane when that happened. However, if you’ve visited a smaller airport, you may have stood just outside the fence when someone reved up their jet engines. Imagine that, but even louder, and moving on normal roads. Should be fun for everyone.

Yeah, the y-axis is unlabeled, but at least the title still tells you what it is: traffic. Doesn’t even have any numbers, so there’s no need to ask about the unit either.
This is more like the graphs made at the marketing department where km becomes KM, because it looks cooler. Same goes of MG, because why not. Is that milligrams or megagrams? Don’t worry about it. I mean, it’s just numbers, so who cares anyway. It’s not like anyone tries to calculate something with them. It’s well known in the marketing department that no human on earth is able do things like that.

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 1 month 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.
- Comment on The Amount of Electricity Generated From Solar Is Suddenly Unbelievable 1 month ago:
China is already on it.
- Comment on xkcd #3115: Unsolved Physics Problems 1 month ago:
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.
- Comment on xkcd #3113: Fix This Sign 1 month ago:
You could also technically fix it using the “missing Missy” method.

- Comment on Which instance should i choose when i share a link? 1 month ago:
IMO link B is the “most original” one. Sort of like an “authoritative source”, if you will.
- Comment on xkcd #3106: Farads 1 month ago:
Imagine what it’s like to calibrate an instrument like that.
- Comment on xkcd #3106: Farads 2 months 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 2 months 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 2 months 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.
- Comment on Pixelfed Uptick in Monthly Active Users 2 months ago:
This should cover it fairly well.
- Comment on xkcd #3097: Bridge Types 2 months ago:
You forgot the trivial case, of not building a bridge at all. Just go around the gap.
- Comment on Pixelfed Uptick in Monthly Active Users 2 months ago:
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 2 months 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 2 months ago:
Both extremes exist. Hence, the condition about loosing your grip on reality.
- Comment on Fediverse Social Media Guide 2 months 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? 2 months 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.
