It depends on how much generation you expect to 'waste'. Many plans are targetting a lot more generation than demand, with numbers sometimes stated as 300% generation potential for solar plus wind.
Why is that always posted without stating the magnitude of the effect? The numbers that you find online are around 15% relative loss at 60°C vs. 25°C panel temperatur (I remember a HN comment reporting 12% comparing peak April to peak July). That is significant, but not world changing, especially for AC.
There are 30 year old still functioning panels in Australia.
Buried in that longevity, is an observation that a fifth of panels degrade faster than expected
The long tail appears on graphs showing the degradation rate per year of the panels, indicating that up to 20% of all samples perform 1.5 times worse than the average.
It exists and does degrade panels but the time horizon is pretty wide. Real world data shows something like 0.5% to 0.7% degregation per year on average.
At the start the degregation is higher and but it slows down with age.
So a 20 year old panel might be at around 80% in the worst case.
Often they are in much better shape.
This seems like a pretty good deal to me.
I am afraid, there are far bigger confounders than that (which they supposedly correct for): you absolutely cannot be a taxi driver if you experience short term memory loss. So those people may have changed profession at a faster rate than say kindergarden teachers or bakers. Tbf. GPS somewhat changed that but with GPS, the spatial information thing makes less sense.
Maybe a naive question: those transactions are traceable. But we assume this admin will not turn itself in. However, such transactions in other nations would be investigated. Are there cases of similar transactions before the US presidents tweets in i.e. Europe?
There's plenty of very suspicious trades in US politics, and presumably European ones too. Actually on both sides of the aisle. Senators putting trades in sectors that overlap with their committee memberships, or these trades appearing in their "blind trusts", with "no input" from the senators. There is so much of it that I am sure there is plenty of insider trading. On average, if you blindly follow their trades, will you make money? The evidence is mixed, and made worse by the fact that the disclosures can be made on paper (pen and paper is allowed!) and the records not all electronified. You can imagine the juiciest trades are probably "disclosed" on a napkin if at all.
There's no doubt it's very dirty business. I just find it lazy thinking to say, hey this one is very suspicious therefore definitely criminal.
So, who is paying the bill here? I am assuming the insider trading itself is zero-sum (its obviously different if what's happing happens only to allow insider trading) and while some (like passive investors like me that buy every month) win a bit, others lose a bit, someone loses big on the futures market. Is that the high frequency and quant traders? Because I assume, someone must be really mad? Especially since, and I again 'assume', that there must be easier and less public ways to bribe the admin
It's you. Every trader who does not have the insider information loses. That's how markets work after all. They collect information by rewarding the use of information. Anyone who has information and uses it is rewarded and anyone who does not is punished.
Even when you are a passive investor you lose. You essentially buy shares at random points in time. When that point happens to fall between the trading of an insider and the public disclosure of the insider information you will get a worse price for that trade.
It isn't even relevant whether the insider buys stocks or other securities directly or trades in futures instead. All information you enter into the market through trades permeates the whole market through arbitrage regardless of where you enter that information.
The losses would be diffuse. In the commodities markets you have a blend of speculative action and real economic activity. The blend is different based on the contract as well. The emini futures are pure financial engineering so it’s harder to track directly to the underlying economic activity.
Wti is much easier. Lots of real economic actors that produce or consume oil are active in those markets.
Maybe a naive question: given that they see better performance with more passes but the effect hits a limit after a few passes, would performance increase if they used different models per pass, i.e leanstral, kimi, qwen and leanstral again instead of 4x leanstral?
That sounds quite interesting. Makes me wonder if sooner or later they will have to train multiple independent models that cover those different niches. But maybe we will see that sooner or later. Thanks for the link.
One would think that LoRAs being so successful in StableDiffusion, that more people would be focused on constructing framework based LoRas; but the economics of all this probably preclude trying to go niche in any direction and just keep building the do-all models.
The SD ecosystem in large part was grassroots and focused on nsfw. I think current LLM companies would have a hard time getting that to happen due to their safety stuff.
Fine-tuning does exist on the major model providers, and presumably already uses LoRA. (Not sure though.)
We saw last year that it's remarkably easy to bypass safety filters by fine-tuning GPT, even when the fine-tuning seems innocuous. e.g. the paper about security research finetuning (getting the model to add vulnerabilities) producing misaligned outputs in other areas. It seems like it flipped some kind of global evil neuron. (Maybe they can freeze that one during finetuning? haha)
Probably just didn't really buy the house. Many houses are part of an association (BRF). When you buy one, you practically only buy the right to live in the house plus a share of the entire association. The fee that she paid was towards that association for things like maintainance, managment, trash-fees, internet, parking, likely heating and water, and possibly interest on the associations loan. It's just a different structure that many countries have for flats in a building, in this case applied to single family houses.
Here in Australia, I’ve seen what we call “strata title” applied to “single family homes” before (American terminology, we’d say “detached houses”) - it is uncommon, much more common with apartment buildings or townhouses/villas/semidetached (you share walls and maybe the roof with your neighbours, but there is no one above or below you)-but not completely unheard of
Would be cool if it could also de-knit to modify clothing or reuse later. I.e if there is a hole: automatically deknit, splice in a replacement and fix it. Or if your belly growth: deknit and make that section slightly wider.
And can you use finer yarn as well, like lace? The reason a sweater is knit like it is, is because of the tradeoff between knitting time and material needed. But if labor becomes free, you should be able to knit much bigger yet more delicate stuff.
I never understand those calculations. You can buy houses in Berlin from around 350k. Maybe not in that area you are looking but still. With something like 600 to 800 sqm ground, house around 100 sqm, quiet neighborhood, 10 min walking to S-Bahn (i.e my grandmothers neighbors house that was sold a few month ago). Probably add 100k for renovation. But with 3.5k of savings a month (from 6.5k easily possible), you have paid it of in ~10 years.
Also, solar production and heating needs are anticyclical.
Also, the European grid is big (the biggest!), but not so big it can deal with seasons and weather patterns. Yet. Or ever.
The idea was that gas would fill in the gaps, until energy storage at scale becomes a thing (no, it is still nowhere near scale, only gas reserves can fill that role right now). Germany is investing heavily in hydrogen to fill this gap, but barring fundamental breakthroughs, I think it's a pipe dream. A 90% (roughly) total efficiency loss means 1000% oveprovisioning of generation capacity. That's expensive, even when cheap.
