Higher refresh rates for movies are meh at best, VRR OTOH is a godsend as 24Hz just won’t fit into 60Hz. Gaming, too, is much nicer even at pedestrian framerates when you have VRR, figures that delayed frames are quite a bit less noticeable than dropped frames.
- Comment on Germany hits 62.7% renewables in 2024 energy mix, with solar contributing 14% 3 weeks ago:
Depends on whether you grow crops specifically to turn into fuel or ferment waste that would otherwise ferment in the open.
The main point on the European level revolved around whether construction of gas plants should get access to some green fund or the other, to which the answer is yes because they’ll always carry some on-demand load, and seasonal storage is bound to include syngas because we’ll need that stuff anyway as chemical feedstock.

US/Canadian border from roughly Vancouver to Winnipeg. Berlin is further north than Saskatoon, Karlsruhe is on the 49th parallel. The lot of mainland Europe is north of Albuquerque. In fact much of Tunesia is north of Albuquerque. Miami is on about the same parallel as Bahrain, Orlando on the same as New Delhi.
- Comment on German Power Slips Below Zero as Negative-Price Phenomenon Grows 3 weeks ago:
They introduced some kind of caps (don’t remember the details) on negative pricing quite early on, from what I understand it would have been very lucrative in the last decade or two to get into grid-scale battery storage without those caps.
One thing I remember is Flensburg building, pretty much on a whim, a water storage tank with immersion heater, an investment that amortised within a month or two as they were literally getting money to put surplus electricity into their district heating.
There’s got to be some rules as to what you can do with electricity you by at negative prices, e.g. not just put an immersion heater in the ocean, maybe some prioritisation as to who gets the energy first just as there is on the production side (fossils have to shut down and pay if they don’t do that fast enough while renewables get to produce energy), but overall I don’t see why there should be a limit on negative prices.
- Comment on Does Lemm.ee Have a TOS? 3 weeks ago:
AFAIU (IANAL, much less an Estonian one) what’s usually considered ToS aren’t really necessary because you’re not entering a contract with lemm.ee that would bind anyone to anything – e.g. you’re not paying usage fees so there doesn’t need to be a stated policy on sitebans because if you went to court over a ban the court would ask “which services did you buy that they did not provide?”, then throw the case out.
That said this is the EU so there’s a privacy policy linked in the footer. It’s a GDPR requirement.
- Comment on ‘If 1.5m Germans have them there must be something in it’: how balcony solar is taking off 5 weeks ago:
Backflow isn’t an issue because the inverters don’t produce high voltage if they don’t see a frequency to sync to. Which is also how they get away with having exposed prongs. Which, consequently, means that those installations don’t make you independent from the grid. They also only feed into one phase, or better said I haven’t seen any three-phase ones.
You also need to register them with your supplier, but it’s not a matter of asking for permission, just notifying them. The idea is that they should be able to deal with 800W backflow on a single phase easily given that you can easily pull 3600W on a single phase from a single outlet, district-level transformers aren’t unaccustomed to skewed loads.
There’s also no requirement for a modern meter, a good ole Ferraris one suffices – during backflow it’s going to turn backwards. Utilities don’t like having that little data to go on but again, it’s just 800W.

UHT does, 140C for 2-5 seconds. Shelf-stable without refrigeration for up to nine months unless you open it.
Frankly speaking the difference between milk from cows with good diet vs. from cows fed protein slop is greater than between the modes of processing.
Still have PTSD from my mother feeding me raw milk – unlike in the US it’s legal here, also heavily regulated so it wasn’t a health risk microbiology-wise but boy am I sensitive to even slight off-tastes in milk because yes you’re going to interrupt the cooling chain and no that fridge doesn’t have 8C. Unless you’re a cheesemaker or such and it’s necessary for the process, stay away from raw.
And, no, it doesn’t have health benefits. Maybe if your kid doesn’t play outside in the mud and the milk is the only source of germs they’re exposed to, then it may help them to not develop autoimmune disorders. Be sane, choose mud over milk.

The kicker is that in any member state that’d be politics trying to bury something in procedure, while on the European level it’s the only way to get anything done. Leave out a step and the thing just fizzles because noone even knows about it.

- Comment on Mastodon Says App Downloads Up 47% on iOS Amid Twitter Exodus 2 months ago:
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.
- Comment on Mastodon Says App Downloads Up 47% on iOS Amid Twitter Exodus 2 months ago:
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.
- Comment on Anon questions our energy sector 2 months ago:
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 actually 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.
- Comment on Anon questions our energy sector 2 months ago:
What makes iron is the lack of O in Fe~3~O~4~ (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, and the carbon that’s used in alloying, well, it’s not in the atmosphere is it.
You can rip the oxygen off iron 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.
- Comment on Anon questions our energy sector 2 months ago:
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. Just over ten megs per language pair.

- Comment on Anon questions our energy sector 2 months ago:
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.
- Comment on Anon questions our energy sector 2 months ago:
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”.
- Comment on Anon questions our energy sector 2 months ago:
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.

- Comment on Domination 2 months ago:
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
dominatesg : B -> X
if there is anh : B -> A
such thatg = 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. - Comment on Know Nut November 2 months ago:
Mostly they’re dried, including pod, the rest is genetics.
They are botanically nuts, though: They are indehiscent, meaning they do not open to release their seeds. They’re also fruit. It’s e.g. pine nuts which aren’t nuts.
I guess making a distinction, in the culinary context, between nuts and peanuts makes sense because allergy considerations, legumes are a class of their own there.
- Comment on Tiger Predators 2 months ago:
Tigers are territorial and solitary but quite social, they don’t usually get into fights when they meet, that only happens when they have an actual territorial conflict because there’s too many tigers on too little land. They’re perfectly fine with others visiting their prowling grounds, they might even hunt together, just don’t overstay your welcome. Actually not that terribly different from how humans treat their houses.
- Comment on Know thy enemy 2 months ago:
Everything that comes out of a petrochemical plant can be made without oil, in fact BASF had recipes in place for decades now and is switching sources as the price shifts. Push come to shove they can produce everything from starch. It’s also why they hardly blinked when Russia turned off the gas.
The carbon that actually ends up in steel is a quite negligible amount (usually under 1%, over 2% you get cast iron), you can get that out of the local forest, and to reduce the iron hydrogen works perfectly, the first furnances are already online.
- Comment on your mom falls significantly faster than g 2 months ago:
Quick intuition boost for the non-believers: How do things look like if you’re standing on the surface of the bowling ball? Are feather and earth falling towards you at the same speed, or is there a difference?
- Comment on your mom falls significantly faster than g 2 months ago:
As to “what’s falling faster” my point is still that everything’s falling at the same speed, because the only non-arbitrary reference point to measure things from is the centre of gravity of the whole system, earth, feather, ball, all of them together.
Well it may still be arbitrary, but at least it’s not geocentric or feathercentric or ballcentric. All three can be unhappy with the choice which means it’s fair.
Flip that reference point to the earth though and yes the ball is approaching ever so slightly faster than the feather (side note: is our earth spherical or are we at least making it an oblong?). Flip it to the ball and the feather is falling a lot slower towards it than the earth is. Which is probably how I should have started explaining this: The mass difference between feather and earth with respect to the ball is so massive that it actually makes quite a difference while between feather and ball wrt. earth it’s negligible.
