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 4 days 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 1 week 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 3 weeks ago:
This should cover it fairly well.
- Comment on xkcd #3097: Bridge Types 3 weeks 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.

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 4 weeks ago:
Both extremes exist. Hence, the condition about loosing your grip on reality.
- Comment on Fediverse Social Media Guide 4 weeks 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? 4 weeks 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.

Memories of Morrowind…
- Comment on This graph but with fediverse apps? 4 weeks 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. 4 weeks 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 1 month 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.
- Comment on Lemmy is suddenly weird 1 month ago:
I’ve seen something similar happen when a site doesn’t load all the way. Refreshing fixes that unless something has gone horribly wrong.
- Comment on xkcd #3084: Unstoppable Force and Immovable Object 1 month ago:
This one is a bit counterintuitive. My maths teacher explained it like this. Take a look at this graph. If you approach zero from the positive side, it looks like the line goes to infinity. If you approach zero from the negative side, it appears to go to negative infinity.
Is it both, is it zero, is it all the values? The canonical answer is “undefined”.

First billion years free. After that it’s 17.99 per millennia.
- Comment on xkcd #3084: Unstoppable Force and Immovable Object 1 month ago:
These kinds of contradicitons exist in made structures, such as laws, rules and regulations. In situations like that, a judge has to pick which rule to follow and which one to ignore. The first time that happens, it becomes the standard solution (precedent) for those kinds of problems.
- Comment on xkcd #3084: Unstoppable Force and Immovable Object 1 month ago:
I choose to believe that the universe will crash due to division by zero, floating-point error, integer overflow and segmentation fault, all of them occurring simultaneously. The objects will experience infinite velocity and infinite forces, there will be rounding errors, the system will run out of RAM and storage space. The universal CPU will max out all threads, and run out of cooling capacity. The hardware catches fire, the entire universe immediately collapses into a singularity, resulting in a new big bang as the system reboots. Oh, and the log files are corrupted, so good luck troubleshooting that one.
- Comment on Biwatt releases 4.5 kWh sodium-ion battery - Energy Storage 1 month ago:
In theory, you can stack cells any way you like, and calculate what the current, voltage and capacity should be. However, those simple calculations don’t consider what the effects might be. Due to material limitations, only certain voltages and currents are safe. Go beyond the limits, and things begin to burn.
Also, these are modules, not cells. Each module probably contains some sensitive electronics that certainly can’t handle any random voltage or current. My guess is, that’s where you’ll find the first bottle neck.

What happened to the ice cream ball with a chocolate core hypothesis? I think it looks like it could be a huge ball of Viennetta.

Yikes!
Anyway, thanks for the clarification.

Next step in the playbook is to outlaw all the minor news outlets that do cover this stuff. Is trump already working on that?
- Comment on xkcd #3081: PhD Timeline 1 month ago:
Totally out of the loop. What’s goin on?
