  • Mastodon Says App Downloads Up 47% on iOS Amid Twitter Exodus

  • lemm.ee currently even proxies links to external images, sunaurus identified some issues with it, storage wasn't one of them. Storage requirements are going to look quite differently if you're lemmynsfw.com but it's not particularly hard to get enough donations to afford a couple extra TB a month. Much, much cheaper than paying admins an actual wage where I think the actual scaling pain will be.

  • hink about how angry people get at the idea of tipping for ANYTHING and then wonder how many of those are throwing significant cash at your favorite lemmy or mastodon instance per month.

    a) it's not significant amounts, it's quite cheap, per user, to run lemmy, e.g. lemm.ee is one of the bigger instances and costs 200 Euro a month, b) tipping 20% on a bill that doesn't even include any service is not the same as donating to a service you like. This is more like a patreon which doesn't lock anything for non-donating users.

  • OMG yes I said "blast furnace to reduce steel". I meant "to reduce iron [to produce steel]". Obviously: What else would you use hydrogen for in a blast furnace?

    But "reduce steel" is still, at least colloquially, correct for recycling steel: Scrap has rust on it so it also needs to be reduced. Which you would've realised instead of trying to turn this into a silly gotcha if you knew what you were talking about.

    Go ahead, do tell me about your plan on how to produce steel, from ore, without getting fossil fuels or hydrogen involved. Charcoal? Could work, but I don't think the economics make sense.

  • What makes iron is the lack of O in Fe3O4 (that's magnetite, other ores are similar). Carbon for alloying is not an issue it can be easily covered by biomass, you smelt the magnetite by combining it with hydrogen resulting in iron and (very hot) water, no carbon involved, then you add carbon, something like 2% thereabouts, to get steel. Add too much and you get cast iron. The overwhelming majority of coke used in the coke process is not used for alloying, but smelting and reducing the iron. That part of the steel making process is completely decarbonised in the hydrogen process, and the carbon that's used in alloying, well, it's not in the atmosphere is it.

    You can rip the oxygen off iron ore with electricity but that's less energy-efficient than taking a detour via electrolysis. It's different with aluminium, there using electricity directly is more efficient.

    Sad to day I now understand your point of view. Natural gas wins.

    If you think that's what I'm saying then no, you don't understand my POV.

  • In essence, yes. And we need the hydrogen/ammonia/methane/methanol/whatever anyway to do chemistry with, so we'll have to produce them in some renewable way anyway, and at scale. Using them in peaker plants is only a fraction of the total use.

    Even with fusion up and running we're going to do hydrolysis. You can run a car on electricity, or domestic heating, also aluminium smelting, but not a blast furnace to reduce steel nor a chemical industry. Hydrogen, in one form or another, is the answer to all of those things. As things currently stand the market is in its infancy but the first pipelines are getting dedicated to hydrogen, the first blast furnaces made for operation with hydrogen are up and running... and the hydrogen mostly comes from fossil gas. It's a bit of a chicken and egg problem you need demand to have supply but you need supply to have demand, so kick-starting the demand side by supplying it fossil hydrogen makes a lot of economical sense, that means that the supply investments can go big and be sure that they'll have customers from day one.

  • Yes it's a good thing and it's more locally-running stuff that they're investigating. Things like fuzzy search on your history, tl;dr bot, etc.

    Malware site detection would be another idea, though they of course already have a non-local solution for that. Maybe, we do have to come full circle after all don't we, a model that can give you an estimation of how likely it is that the page you're looking at is AI slop.

  • No, it isn't. It's integrated into the browser, and running locally.

    I'm just saying that if you a) want translation and b) privacy then you want c) AI in firefox. Because, you know, translation models are AI tech, figures that natural language is too fuzzy to do in other ways.

  • Not just building it's shipping by default. That is, language detection and code that displays a popup asking you whether you want to download the actual translation model is shipping by default. About twelve megs per model, so 24 for a language pair.

  • When’s that going to happen? Right after the green hydrogen revolution?

    Already happening, on a small (but industrial) scale. You can buy that stuff off the shelf, but it's still on the lower end of the sigmoid. Most new installations right now will be going to Canada and Namibia, we'll be buying massive amounts of ammonia from both.

    Sorry, I didn’t think someone would deny the existance of dunkelflautes. It’s currently happening in Germany.

    Yes and elsewhere in Europe the wind is blowing. Differences in solar yields are seasonal (that's what those three months storage are for, according to Fraunhofer's initial plans), but reversed on the other side of the globe, and Germany would be better situated to tank differences in local wind production all by itself if e.g. Bavaria didn't hinder wind projects in their state. The total energy the sun infuses into the earth does change a bit over time, but that's negligible. In principle pretty much zero storage is needed as long as there's good enough interconnectivity.

    ...meanwhile, we'll probably have the first commercial fusion plant in just about the mean construction time of a fission plant.

  • Wouldn’t it be better to go fossil free. Given, you know, climate change.

    Gas can be synthesised and we're going to have to do that anyway for chemical feedstock. Maintaining backup gas plant capacity is cheaper than you think, they don't need much maintenance if they're not actually running.

    That’s physically impossible for a place the size of Germany, much less Europe.

    Unless we use a different technology, that is not renewables + storage?

    It's not technology it's physics. It is impossible for there to be no wind anywhere, at least as long as the sun doesn't explode and the earth continues to rotate and an atmosphere exists. If any of those ever fail electricity production will be the least of our worries.

    Technology comes into play when it comes to shovelling electricity from one end of the continent to the other and yes we need more interconnects and beefier interconnects but it's not like we don't know how to do that, or don't already have a Europe-wide electricity grid. The issues are somewhere in between NIMBYism regarding pylons and "but we don't want to pay for burying the cable earthworks are expensive".

  • The watthours is what gas is for. Germany's pipeline network alone, that's not including actual gas storage sites, can store three months of total energy usage.

    ...or at least that's the original plan, devised some 20 years ago, Fraunhofer worked it all out back then. It might be the case that banks of sodium batteries or whatnot are cheaper, but yeah lithium is probably not going to be it. Lithium's strength is energy density, both per volume and by weight, and neither is of concern for grid storage.

    Imagine bridging even a short dunkelflaute of 2 days.

    That's physically impossible for a place the size of Germany, much less Europe.

  • At least there's only a single way to tell the computer "ok, execute this command". And you see the command written in plain text before you.

    And, no, no useful interface is intuitive because computers just have too many functions. There's no intuitive appliance in the world with more than a temperature knob and a timer knob. Knowledge is always required, be that cultural or by RTFM.

  • EU fines are working. Not in the sense that they would prevent companies from trying to do shit, but in the sense that they shape up once it has been levied: Understand that those 800m are a shot before the bow. If the behaviour continues, there's going to be daily punitive fines that very quickly become very unaffordable.

    I mean, what is the money being used for?

    Goes towards the EU budget, reducing the amount the member states have to pay in. In other words Berlaymont doesn't gain anything from levying fines, their budget stays the same.

  • It's still quite obscure to actually mess with AI art instead of just throwing prompts at it, resulting in slop of varying quality levels. And I don't mean controlnet, but github repos with comfyui plugins with little explanation but a link to a paper, or "this is absolutely mathematically unsound but fun to mess with". Messing with stuff other than conditioning or mere model selection.

  • I mean, sure, that's a domination relation but it doesn't really get at the core of domination, either, but tells us where dominance fits in the larger context. The core idea is much easier: f : A -> X dominates g : B -> X if there is an h : B -> A such that g = f . h. That is, if there's a way to turn potato mash into food, and one to turn sliced potatoes into food (say, a hot pan with some oil) then frying mash dominates because there's a way to turn potato slices into mash, but none to turn mash into slices. It can also be the case that two functions dominate each other, e.g. when you look at cooking tea with a teabag, and without a teabag: As bagged tea can be unbagged, and unbagged tea bagged, both dominate, in fact, they're equivalent. All this is up to equivalence of fried potatoes and hash browns which can be easily established by trying both with eggs and ham, and both with apple sauce. Best paired with a doughnut of coffee1.
