  • So, the server that hosts the front-end via Tor will see the exit node connecting to it

    The onion eliminates the use of exit nodes. But I know what you mean.

    I appreciate the explanation. It sounds like replicating the backend and DB on the Tor node would help. Not sure how complex it would be to have the DBs synchronise during idle moments.

    Perhaps a bit radical, but I wonder if it would be interesting to do a nightly DB export to JSON or CSV files that are reachable from the onion front end. Scrapers would prefer that over scraping, and it would be less intrusive on the website. Though I don’t know how tricky it would be to exclude non-public data from the dataset.







  • I’ve not tried the onion instance since reporting the data loss issue, but in principle a the onion host could be a good candidate for read-only access (scraping).

    Would it perhaps make sense to redirect the greedy subnet to the onion instance? I wonder if it’s even possible. The privacyinternational website used to auto-detect requests from Tor exit nodes and automatically redirect to their onion site. In the case of mander, it would do that for the subnet giving problems. They are obviously not using Tor to visit your site, but they could have Tor installed. You would effectively be sending the msg “hey, plz do your scraping on the onion node,” which is gentler than blocking in case there is more legit traffic from the same subnet. That is assuming your problem is not scraping generally but just that they are hogging bandwidth that competes with most users. The Tor network has some built-in anti-DDoS logic now, supposedly, so they would naturally get bottlenecked IIUC.

    I guess the next question is whether the onion site has a separate allocation of bandwidth. But even if it doesn’t, Tor has a natural bottleneck b/c traffic can only move as fast as the slowest of the 3 hops the circuit goes through.







  • That wouldn’t exactly hit the mark because a ghost community /can/ be active. The problem is that if you have:

    • someCommunity@originalNode
    • nodeA/someCommunity@originalNode
    • nodeB/someCommunity@originalNode

    You can see the local copy of nodeA/someCommunity@originalNode if you are on nodeA. But you don’t know it is orphaned and you are in a bubble. People on nodeB can see posts in nodeB/someCommunity@originalNode, but not nodeA/someCommunity@originalNode. There is no signal that you have been cut off, and that your post will only have a local audience.

    We already have transparency of activity, but not transparency of scope and reach.

    I would even say adding the transparency is just a start. The real bug here is that the fedi has not figured out that nodeA and nodeB need to sync with each other regardless of the parent.





  • EV car buyers have a delusion that their old ICE car is removed from the planet. ICE cars are not being trashed upon replacement. They are shipped to Africa, where the avg. age of a car at the time of purchase is 21 years old.

    Small aircrafts w/an ICE last forever because they are very well maintained (by law in fact). The cost of replacing an aircraft is also very high, so economic pressure also ensures a long life. The same would be true of ICE cars in your region if the economics of your region demanded it. Reguardless, unless you also plan to eliminate worldwide poverty in a couple decades, the ICE cars are not going away.








  • What if I can hear wi fi? How could I tell?

    Wouldn’t it be bothering you if you could?

    Well, I suppose not necessarily… I hear a hum but it does not bother me because I don’t generally fixate on it. When I notice it, I then realise I’m being lazy and need to get out of bed and get my attention on something. Some people suffer, like Diane Schou, who moved to a town that didn’t trigger her electromagnetic hypersensitivity.

    I suppose a test would be to enter a sound-proof room which then also has a faraday cage, and get tested. The tester would have controls for emitting sounds mostly outside the statistical hearing range, along with one to turn on a wifi AP, and some dummy switches that emit nothing. Then for you to raise your hand when you hear something. I read about someone taking a test like that, and she raised her hand whenever some electronmagnetic something was played (wi-fi iirc). It was something that was unusual and surprised the researchers. I cannot find the story on that now. Might have appeared in Wired mag… not sure.



  • I appreciate the research and references.

    For the greenhouse gas emissions, the electric kettle should pull ahead in the future as renewables take over

    Perhaps in most regions outside of populist-rightwing-controlled regions, that will be the case. ATM I am not in the US but still they are tearing down the nuclear power plants and building 3 new natural gas fired plants. So progress is moving backwards where I am.

    Centralised gas burning would be more efficient than burning it on a domestic stove, but hard to grasp that the difference would be enough to exceed conversion and transmission losses. Worth noting that there are a couple ways to get hot water from gas:

    • simple pot on stovetop
    • water runs through a coil of fire-heated pipe inside an insulated box – aka a tankless combi boiler

    The 2nd option would not give boiling water, as I would not want boiling water to run through the domestic pipework, but I wonder how a small tankless gas-fired tea water appliance might do as far as increasing the gas efficiency, should it be invented.

    In any case, if electric-fueled heat were generally efficient, I would expect the gas-fired combi boilers to be much less popular. Though note as well that economy is not closely tied to efficiency. Natural gas cost per kWh is much cheaper in my area than electric cost per kWh (by a factor of 2 I think).



  • Gas has a conversion efficiency of 100% but not all of it every the kettle. That leads to efficiencies lower than the electric ones.

    Yes but you’re only talking wall to water. From energy source to water gas is the most efficient because it does not have the lossiness of generation and transmission that electric does.

    With good induction it is also faster than every other method so that would be my choice if I had an induction cooker.

    You’re purely talking boil times. But the end game is brewed tea, in which case it cannot be faster because after boiling the water you still need ~1—3 min to brew it. That’s why the inline heating elements in dispensors are interesting. It starts brewing immediately so the 1m50s it takes to boil all the water can be neglected.


  • I struggle to believe water pooled up enough to carry stuff. Condensation is possible perhaps to the extent of having some invisible amount of sweat. Unless there were puddles that formed and evaporated before I saw it. Though it’s a short fridge. The top of it is at eye level so I see the top every day.

    Here’s another pic:
