  • Is there a safe and private way to verify that I am in fact a real human on the internet?

    In Finland we have this thing called ‘mobile verification’ which I use almost daily. It’s a service where my phone number is verified to my identity in a secure manner (via multifactor bank account on my case but there’s multiple ways to achieve that verification) and it works as an “middleman” where I can just click an icon on a website, feed in my phone number to the identification service, check MFA on my cellphone and then I’m shown a web page where the identity provider shows what information is delivered to an original website. Most of the cases, at least on my usage, it sends out my social security number, so that I can access my invoices, sign legal documents, check my tax forms or whatever I’m doing but the underlying system can provide pretty much whatever data they have stored. There’s no technical reason why it couldn’t be used to verify that I’m an actual human being too.

    Say, if that was used in Lemmy (unlikely as the service costs something per each verification), identity provider would just send to my instance that I’m an actual human being but nothing else. The instance could then store that data and show a pretty blue checkmark next to my username without any personal data from me.





  • Generally, heating and cooling are the main energy consumption for domestic purposes. next up is the car, and then electrical consumption. (from what i remember).

    I suppose it depends on where you live. Our house consumes something over 20 000kWh per year as our heating is also electric (and rest of the consumption is pretty neglible compared to heating) and we also have a fireplace which consumes around 15m³ of firewood, depending on how cold winter happens to be. Electric grid here has a ton of renewables and nuclear, so co2 footprint should be on the smaller side compared to global average.

    Also, as google and microsoft (among others) shoehorns AI “answers” to everything that adds up, but private use seems to be quite insignificant anyways.



  • Because its still bullshit.

    Obviously. But I have no context on how much my actions create co2 in the first place. I assume driving a car generates a majority of it, or maybe heating the house, but I still don’t have any clue how many kilograms that might be. But what I do know is how many kilowatts my house consumes electricity and at least roughly how much our appliances use, so if you want to try and blame me for consuming precious resources by generating text or watching a video at least give me an measurement I can easily comprehend.


  • Is it just me or is that stupid way to measure consuming computing power? The CPUs themselves doing computations do not produce any pollutants (unless you calculate how much of that is created during manufacturing ang logistics, which I doubt). It’s the (without question stupidly large) energy consumption which might, but big players are at least greenwashing their actions by using renewable energy more and more.

    Why not create comparison like “generating 1000 words of your fanfiction consumes as much energy as you do all day” or something more easily to compare.




  • It fits 188 KiB on a sheet of letter sized paper

    Maybe I won’t use that to back up my photo library as few rough web searches suggests that the pile of paper would be something around 500 meters tall. Pretty neat technology and I suppose if you really need something stored you can etch that to stainless steel plate or something similar, but data density isn’t the best around.


  • It’s the same in any country with buildings over 100 years old.

    In here 100+ year old houses are pretty common but practically all of them still have at least somewhat up to date electrics with that 3-phase input. It’s been around for decades after all. My house is built originally 1928 and my mothers house is from 1909 and both of them have 3x25A main breakers with those 380V 16A CEE sockets around.

    And as garages commonly double as a work space with 3-phase induction motors on the tools it’s still pretty common to have that 3x16A available as it’s not that much more expensive to pull 5x2.5mm² cable to the garage compared to 3x2.5mm² for single phase 16A outlet.



  • Though, if I remember correctly, your outlets have resettable breakers?

    Here in Finland we don’t have breakers on outlets themselves, they’re all on electrical panel. But we have ‘automatic fuses’ which you can reset, they’re just referred as ‘fuse’ almost always. Also, as our house is older, the 25A main fuses are actual porcelain ones, but new ones obviously have those automated too. Similarily, nearly all of the fault current protectors are on electrical panel instead of individual outlets.

    And in here nearly all fuses for lights, sockets and everything are either 10 or 16A with bigger main breakers, normally 3x25A for individual houses.





  • You could get around with a normal file share service (assuming you already are using one) via tinyurl or similar redirect. I don’t know how much the free services track you or if they have other security implications, but I have couple of domains laying around and it would be pretty trivial to just create HTTP redirect from “class-a.up.mydomain.foo” to my nextcloud upload link.


  • Also when sodium hydroxide reacts with acid it releases CO2 and it affects growth of at least some fungus. Also, if a brick sized fuel cell can provide 1kWh and single transatlantic flight consumes at least 20MWh you’d need a pile big enough to build a house which doesn’t sound feasible.

    But I’m not a chemist either, I suppose it boils down to comparing negative effects between this new cell against kerosine. Plus there’s always the case which affects any new kind of storing energy where it’ll be indefinetly ‘ready for market in next 5 years’.


  • That’s something along the lines I do as well, but your methods are far more in depth than mine. I just glance around documentations, how active the development is and get a rough idea if the thing is just a single person hobby-project or something which has a bit more momentum.

    And it of course also depends on if I’m looking for solutions just for myself or is it for others and spesifically if it’s work related. But full audits? No. There’s no way my lifetime would be enough to audit everything I use and even with infinite time I don’t have the skills to do that (which of course wouldn’t be an issue if I had infinite time, but I don’t see that happening).
