  • I’m a network engineer and I run ipv6 natively in all of our datacenters. There are even a handful of end systems that have ipv6 native networking stacks with ipv4 sockets for our non-ipv6 compatible applications. IPv6 issues are basically self-inflicted at this point by companies that see their IT systems as cost centers, or by basilisk directors who’s knowledge stopped in the 90’s.

    If the labor force could opt out of the rat race because they didn’t have to work, then they gives them immense power especially considering what they have now. Of course the necessities would have to be controlled in a not-for-profit manner so that you can’t just have some land baron that adjusts the cost of rent and food upward to ensure it eats up all the UBI, same with utilities/internet/etc.

    But for consumerist goods that people want because they enhance life, if people could realistically withhold their labor unless the capitalist offered equity etc in industries that produced those things, you would quickly see the power of the leaders of those industries wane significantly.

    Seems novel. But from a security aspect, if OpenSSH has security vulnerability that allows an unauthenticated user to login, via whatever means, once you are in the system as a non-privileged user, you are now free to use the same vulnerability to get root.

    Basically this exercise is like using two locks that have the same key to open them. If the same key opens them, then a weakness in one, is now a weakness in the other so why bother with two identical locks?







  • Did you miss this?

    Some numbers. This facility stores 1400MWh, on 2,000 acres or (~8,000,000 sq meters) Much greater then your 40,000sq meter estimate. Plus you said about 33GWh for a day. Well you’d need ~24 of these facilities to cover just Berlin.

    You estimated 40,000sq meters, but that is off by a factor 2000. This is for a facility that actually exists. Theoretically it could be improved, but those theories aren’t being built right now. So based on a grid storage plant that actually exists, berlin would need 48,000 times more square meters dedicated to energy storage then you estimated and in any case, THEY DON’T EXIST and aren’t being built.



  • I dont’ understand the issue here. Is that picture part of some specific VPS’s logo or is it part of the title/theme of the article? I think it’s very poignant, though obviously edgy, if it’s the latter. If your VPS provider isn’t censoring content, then obviously that means Nazism will be able to exist along with militant socialism advocating violence against capitalism. That is kind of the point of the article right? To determine which VPS is actually not going to censor.


  • Your only argument here seems to be space and I don’t see that as a big problem. A few soccer fields worth of land distributed in the vicinity of each bigger city doesn’t seem like a lot to me.

    It’s 1000x “a few soccer fields” for a city like Berlin, and we have zero other working grid level storage facilities in the world at that scale. The handful that do exist are <100MWh, and are meant for specific situations, not for powering 100% renewable cities. No one is building grid-level storage, it’s a pipe dream. But it’s pushed as a solution because the fossil fuel industry knows it will never happen, but what will happen is more fossil fuel plants will be built.


  • You’d be wrong then.
    https://en.wikipedia.org/wiki/Palo_Verde_Nuclear_Generating_Station This is a Nuclear power plant in the middle of a desert so no large bodies of water near by, though obviously the design could be adapted to places where water was more plentiful.

    It takes up 4000 acres (16,000,000 sq meters) Produces (not stores) 4GW (~32,000 GWHrs annually) For comparison, the US Produces 42400000 GWhrs annually. And it cost $14Billion in 2023 dollars

    If I were to replace all of the US’s generating capacity with nuclear, fully shunning renewables. it would cost ~$19Trillion and take up 5.3million acres (which is the minimum amount of land that could be taken up by any currently existing power generation system https://ourworldindata.org/land-use-per-energy-source ). But no one wants to do that (although it would be amazing for the atmosphere). Instead we merely need to supplement renewables with base-load power, and we don’t actually need power storage at all.

    The ideal ratio between renewable power and base-load power I do not know. But during the day in Texas in July it’s about 50% higher then at night. https://www.eia.gov/todayinenergy/detail.php?id=42915

    So even if we assume renewables don’t work at night, base-load only needs to account for ~33% of total electric production at the worst case. Much more manageable then the ~6.5hrs/6TWhrs of energy storage required for a 100% renewable grid to function.

    The tl;dr, is that while renewable powered storage is possible, the magnitude of storage required to eliminate base-load generation is VASTLY larger then anti-nuclear advocates realize, and not feasible today (or possibly ever). This belief stems from is fossil fuel propaganda, especially in Germany where the fossil fuel interests understand they have nothing to fear from renewables because a renewable heavye grid is only possible with fossil fuel plants and every year every nation burns more fossil fuels then they did the year before*, Germany included. It will stay that way until mass famine hits and the human population of the earth collapses, unless we stop burning fossil fuels. The only viable non-fossil fuel replacement for our large and growing baseload capacity is nuclear power.

    *note that fossil fuels aren’t only used for energy production, transportation and shipping are huge areas as well.
