- Comment on How difficult would it be to live in a modern-day developed country without a smartphone? 1 day ago:
Kids and elderly people are already doing all of that, so it is technically possible, but inconvenient. You would also need to outsource your smartphone activities to someone else to actually make it work.
Option 1 seems semi-feasible, but it is getting harder every year. Also, certain activities are already beyond your reach if you’re in this group. As long as you don’t want to do any of those things, you should be fine though.
Option 2 is impossible unless you outsource your phone needs to someone else.
Option 3 is hard, but possible. You would need to limit your activities quite significantly. BTW some homeless people have a dumb phone as their only electronic device. You kinda need to have a phone number in order to barely survive.
Option 4 is the most extreme one. Children and elderly are living like this, but they are also outsourcing everything, so does that count?

Don’t introduce anything too radical, so no tunneling electron microscopes just yet. However, you should be able to use empirical science to debunk BS ideas and move things along that way.
For example, the phlogiston idea was proven wrong in the 1770s when people started burning metals and realized their mass increased in the process. Also, certain compounds can release oxygen, which can maintain a flame in an otherwise empty container. Sounds simple to us now, but back in those days, it was revolutionary.
The idea is that, you have to work within the framework available at the time.

Yes, that helps to lower the total energy cost of boiling the water. It’s better than nothing, but still pretty far from ideal.
- Comment on Why don't these AI data centers build by the ocean? 1 day ago:
Waste heat recovery is a thing, and the economics usually work out in your favor if the feed material is really hot. If it’s only mildly warm, you’ll need a lot of machinery to concentrate the heat and raise the temperature to a useful level. At some point, the investment just gets absurd and the idea gets scrapped.
Using heat as heat makes the most sense, since there are fewer lost steps. Theoretically, you could boil water with server heat, but the massive investment is probably the reason why that isn’t happening everywhere. Running reverse osmosis probably won’t work, because you need electricity for the pumps, and converting heat into electricity comes with significant losses.

Speaking of the north, the answer is yes. You totally can, and should, use the heat for something like district heating.

Besides, having your own FS is pretty bad ass in the same way as running Linux From Scratch.
- Comment on Could I just create my own drive format? 2 days ago:
Doesn’t have to be world changing or even practical. A project like that would still teach you a ton about storage hardware, how file systems work, programming, mathematics etc. Some of these lessons could even be useful, but above all, a project like this should be fun and interesting.
Why do you think people install Linux and run Doom on all the weirdest hardware they can find. This is the spirit that drives innovation.
Don’t let expectations hold you back. Make your own FS, and have fun.
- Comment on Could I just create my own drive format? 2 days ago:
I think I’ve read about a similar project where someone would send packages across the internet, and use the delay as a form of memory. The capacity wasn’t great, but the idea was really cool regardless.

Reminds me of something a coworker once told me. If you had a time machine and went back to the year 1825, there would be an absurd amount of basic chemistry you could discover. Some of it doesn’t even require any fancy equipment, but if you had a proper lab at your disposal, you could become famous in no time.
- Comment on Could I just create my own drive format? 2 days ago:
Making something comparable with ext4 would probably take an autistic genius who dedicates their every waking moment to this project. Someone who eats, drinks and breathes numbers.
Other people can hope to make a fun little project that teaches them about file systems and storage hardware. Might not be a competitor to anything, but it doesn’t have to be. People like to tinker with all sorts of weird stuff, like installing doom on a toaster or something. The way I see it, this FS project is probably in that category.
- Comment on Could I just create my own drive format? 2 days ago:
But we’re on Lemmy, and that comes with a huge selection bias. In fact, you don’t really find that many typical individuals here. A significant part of the population here uses Linux as a hobby, does something technical for a living. Possibly both!
I really don’t think it’s that far fetched to imagine that it’s possible to find someone in here who has the time, energy, enthusiasm, patience knowledge and intelligence to build a new file system. I’m pretty sure you can also find more than one person capable of writing their own drivers or libraries.

Throwing money on lottery can make you rich. Or it might not. Honestly, the odds are stacked against you.
What doesn’t kill you, may make you stronger… unless it maims you for life. People who have survived wars aren’t necessarily stronger. Quite the contrary actually.
- Comment on anyone have personal experience with industrial tourism? 3 days ago:
LOL. I knew I should have read it 4 times before posting.
- Comment on anyone have personal experience with industrial tourism? 4 days ago:
Some factories have public tour days every year. Just look it up on their website.
If you have some kind of an organization behind you, it’s also possible to arrange such tours during other times. You could also make your own industrial tour association, get a bus full of people and start arranging tours with different companies. Just contact the PR disarmament in advance, make some phone calls etc. and you should be able to visit a whole bunch of interesting places.

I’ve seen the same thing too. My guess is, it may have something to do with the instance you’re using.

Oh, so that was fungi? TIL!
- Comment on It might not be too long before animals evolve a rudimentary mechanism to filter microplastics 1 week ago:
What kind of climate shift are you referring to? Like when fungi produce organic acids and aromatic compounds etc, how is that related to shifting the climate in any way?

That’s only a mild annoyance. More serious thought viruses change your behavior by making you buy stuff, join a cult, vote a billionaire or whatever. Those viruses have real consequences.

- Comment on Why is the colour of sunlight different in every country? 1 week ago:
Angle and atmospheric composition. Midday sun doesn’t always come at the same angle, because certain countries are closer to the equator. Also, pollution contributes to the color as well. Just look at some photos from China, and you’ll see what I mean. Natural phenomena like sand and ice can contribute as well.
- Comment on Does it damage my phone in any way it I use a faulty cable to charge it? 1 week ago:
I’ve been observing the voltage and current of a bunch of chargers, cables and phones with a handy little power meter that plugs in between the charger and the cable. I still have no idea whether that hurts the battery or not, but fluctuations certainly do occur.
For example an iPhone just loves to crank up the current every few seconds. If the power supply or cable can’t handle it, the voltage will crash below some tolerable limits set by the phone. In response, the phone will lower the current back to a level where the voltage remains high enough and then the cycle repeats. Interestingly, an iPad or an Android phone I tested don’t do that sort of aggressive current ramping. Those two just figure out a sustainable current in the beginning, and let it be, whereas the iPhone is never satisfied if the current is a bit lower than you would normally get from a good power supply and cable. Either way, I suspect that’s just the BMS doing its thing, and every device seems to have a different BMS.
Will the BMS be able to provide a stable current and voltage to the cell even when the power draws is far from stable? Sounds unlikely to me, but ask an electrical engineer to make sure.
Will an unstable charging power hurt the cell in the long run? Ask a battery scientist. I just know that extreme temperatures definitely hurt it. Also high C-rates are harmful as well.
- Comment on Soup of Theseus 1 week ago:
Hmmm… The description certainly fits. Just by eye-balling the graphs, they look very different from what I got, but I guess that’s just the expected result of running rbinom about a 6 million times. With a smaller simulation, it might not have been so apparent. Also, that’s what you get for skipping the maths and vibing the code without thinking too much about the details. Well, at least i got this far with absolutely minimal effort. :D
It appears that I need to switch to a better distribution. Thanks for looking into this mystery!

Wait, can chili do that? I don’t think I’ve experienced that even though my mouth has been on fire numerous times.
- Comment on Soup of Theseus 1 week ago:
You’re right. I just ran rbinom 1E7 times and found that the probability of over drawing soup molecules is a bit too high for my taste.
When there’s only 1 left, you usually end up drawing 0 or 1 molecule. However, in rare cases, it can be higher, such as 2, 3, 4… molecules.
About 92% was 0, and 7.7% was 1, but the others were not negligible! There’s about 0.3% probability of over drawing, which is way too high for a simulation as serious as this one. In this quick test, there were 20 incidents where rbinom wanted to pull out 4 soup molecules when only 1 was available. We can’t have that, now can we!
- Comment on Soup of Theseus 1 week ago:
If you want, I can increase the sample size. Just need to figure out how to add a timer to the code and set it to run for a few hours, maybe even overnight. A histogram with 10^6 bins should look pretty smooth.
- Comment on Soup of Theseus 1 week ago:
I thought of making a vector with a length of about 1.671398e+25, but then I remembered what one time when when I tried to make a linear model with hundreds of dimensions. So yeah… We have gigabytes of RAM, and it’s still not enough. Not really a problem, as long as you don’t try to do anything completely ridiculous.
Instead, I just made a variable that simply contains the number of soup molecules and another one for the number of water molecules. Far simpler that way.
Here’s where the magic happens:
# Number of soup molecules drawn soup_molecules_replaced <- rbinom(1, replacement_count, prob_soup)
The rbinom function is used to generate random numbers from a binomial distribution. It’s a discrete probability distribution that models the number of successes, i.e. scooping out a soup molecule. Rest of the codes is just basic infrastructure like variables, loops, etc.
BTW the variable names look ugly, because I couldn’t be bothered to tidy everything up. I really prefer camelCase, whereas Mistral seems to prefer underscores. That’s what you get for vibing.
Side note: If you do this kind of stuff for private purposes, you have to rely on your own hardware. If you plan to publish your discoveries, universities and publicly funded supercomputers might be an option. If there exists a Journal Of Recreational Mathematics And Useless Simulations (JORMAUS), I could totally publish this stuff and maybe even run my code on a supercomputer.
- Comment on Soup of Theseus 1 week ago:
Ok, I couldn’t resist. Here are the results of running that simulation 6000 times.
Min. 1st Qu. Median Mean 3rd Qu. Max. NA's 1085 1126 1140 1144 1157 1292 0
This means that about half the time it’s somewhere between 1126 and 1157 spoons.

I’m tempted to run a full simulation that really picks those molecules randomly.

Since excessive consumption of soup probably causes obesity, joint pain, cardiovascular disease, type 2 diabetes, depression and a long list of other conditions, we can unsafely say that the homeopathic soup should cure all of those.
