> When you “cook” a piece of fish in salt and lime (a la Ceviche) you are also altering the protein structures).

When you're cooking a piece of fish, you're not changing its structure using heat and pressure so that globular plant cell structures are transformed into stuff resembling fibrous animal cell structures.

Nothing interesting about the cleanest energy (which is, as everybody knows, nuclear) ? That's desapointing.

I'm glad that some countries have built and are still betting on the half-century years-old tech: fast neutrons reactors, those outputs are equivalent to our regular light-water reactors and which generates no waste (to be precise, most of that waste have a ~30yo half-life, not a big deal)

Indeed, and insurance is already highly regulated. It doesn't seem like it would be very hard to basically say, "you can't consider assisted suicide as an alternative option when making coverage decisions."

Will it still happen somewhat? Yeah probably, but there's also the very real suffering of a human being that needs to be considered. Telling them, "no sorry you have to have a painful and prolonged and undignified death because an insurance company might misuse the option if we give it to you" is pretty messed up IMHO

Which is perfectly fine? You're just using what's abundant to you? And even better, hydro has the ability to control how much it generates. You have a surplus? Let less water flow through the turbines. So it can regulate, something solar can't do, it needs batteries to do that.

The one big upside that I haven't seen mentioned is that rooftop solar is local. So what I overproduce doesn't go on the big grid, it's probably consumed by my neighbor or someone in my street.

All those big power plants, and big consumers of electricity (because they're switching from their current source), will lead to net congestion where you need to decide if you want to increase net capacity... Which is slow and $$$

This year, our advanced Gemini model operated end-to-end in natural language, producing rigorous mathematical proofs directly from the official problem descriptions

I think I have a minority opinion here, but I’m a bit disappointed they seem to be moving away from formal techniques. I think if you ever want to truly “automate” math or do it at machine scale, e.g. creating proofs that would amount to thousands of pages of writing, there is simply no way forward but to formalize. Otherwise, one cannot get past the bottleneck of needing a human reviewer to understand and validate the proof.

This is why I hack the registry to stop updates. I'm on earlier build that is pretty stable, and I am tired of updates breaking this stability for no benefit to me.

Software companies have a toxic business model at the moment. They make software and expect the testing to be done by the end user. There is not even a conversation about it. End users pay to consume bad software that gets patched over time and it also changes over time, and to top it off you don't even own it and it's actually a license.

Of course the solution is to use Linux, but we're in this hole because for-profit companies have aggressive market strategies that force adoption and create interdependencies that make it hard for any other software to compete. It's like the network-effect but for software usage, but I digress.

"They say, ‘It’s not so bad’ or ‘You’re seeing things’ or ‘You’re an alarmist.’

"And you are an alarmist. You are saying that this must lead to this, and you can’t prove it. These are the beginnings, yes; but how do you know for sure when you don’t know the end, and how do you know, or even surmise, the end? On the one hand, your enemies, the law, the regime, the Party, intimidate you. On the other, your colleagues pooh-pooh you as pessimistic or even neurotic. You are left with your close friends, who are, naturally, people who have always thought as you have.

"But the one great shocking occasion, when tens or hundreds or thousands will join with you, never comes. That’s the difficulty. If the last and worst act of the whole regime had come immediately after the first and smallest, thousands, yes, millions would have been sufficiently shocked—if, let us say, the gassing of the Jews in ’43 had come immediately after the ‘German Firm’ stickers on the windows of non-Jewish shops in ’33. But of course this isn’t the way it happens. In between come all the hundreds of little steps, some of them imperceptible, each of them preparing you not to be shocked by the next. Step C is not so much worse than Step B, and, if you did not make a stand at Step B, why should you at Step C? And so on to Step D."

This is an intriguing anti-endorsement; I was too cool for Batman when this came out, but I feel like I have to watch this now haha.

I actually lived near a movie theater that got bought out by someone very weird and ostensibly rich, and they just played bad movies to jeer at and mock, and every... Friday was Rocky Horror Picture Show night. I think the small town I was in revolted and raised money to then buy that guy out, but man what a time. Surprised they didn't screen this steamer lol, is all I'm saying.

Ooof! That sounds rough and also makes me realise a huge oversight in my original comment.

I've been using linux on desktop for about 12 years and will always pick a laptop that's known to have good compatibility otherwise the endless hardware issues are a big timesuck.

Some distros are better than others for hardware support but I think it'd be disingenious to make out like any solve the problem.

If you have a laptop with good support, or even better, a linux specific one, it really is an experience that can work out of the box.

Maybe that's a big part the appeal of being buy-in-a-shoppable. Somebody has figured out for you what works, and you don't have to be your own guinea pig.

Author does not fully address that the CIA effectively funds and directs the rest of the IC. They gate all infrastructure - from networks to satellites to drones. When Congress tried to limit their operations with heavy oversight, they spun out a brand new intelligence agency, classified its very existence, and spun out operations on that side for years before CBO caught on.

Load images lazily — only when needed — to avoid wasting memory upfront. AsyncImage or Kingfisher are the options.

Kingfisher and AsyncImage decompress images into dirty memory, and images are big. They're fairly CPU and memory inefficient from that perspective.

FastImageCache uses memory mapping and is very efficient, but it's 10 years old: https://github.com/path/FastImageCache

I've used Python's asyncio a couple times now, but never really felt confident in my mental model of how it fundamentally works and therefore how I can best leverage it. The official docs provide decent documentation for each specific function in the package, but, in my opinion, lack a cohesive overview of the systems design and architecture. Something that could help the user understand the why and how behind the recommended patterns. And a way to help the user make informed decisions about which tool in the asyncio toolkit they ought to grab, or to recognize when asyncio is the entirely wrong toolkit. This is my attempt to fill that gap.

The article says "people", not humans. And whichever term it is using, it is not referring to undocumented immigrants, it is referring to people, regardless of documentation. "Trump's 'border czar', Tom Homan, has stated ICE does not need probable cause to detain people based on their physical appearance. Homan confirmed ICE has made what he described as 'collateral arrests' of 'many' American citizens". The goal is to arrest at least 3,000 brown people, many of which will end up being US citizens, but that is just collateral damage to them.

The top lithium mining country is currently Australia:

https://en.wikipedia.org/wiki/List_of_countries_by_lithium_p...

Here's a USGS report on global lithium from 1996:

https://d9-wret.s3.us-west-2.amazonaws.com/assets/palladium/...

And the same report from 2025:

https://pubs.usgs.gov/periodicals/mcs2025/mcs2025-lithium.pd...

Over those 29 years world production shot up from 6,300 tons in 1995 to 240,000 tons in 2024. At the same time reserves grew from 2.2 million tons to 30 million tons.

How can reserves go up even as we're mining lithium faster? It's because reserves are defined by a combination of economics and technology. The Earth's crust contains 20 ppm of lithium now and in 1996 (or a million years ago, for that matter). The geology doesn't change but the effort put into identifying potential sources of lithium and means of extracting and purifying lithium does change. Geologically speaking, the Earth has a lot of lithium. World lithium reserves have been increasing faster than they have been depleted, because the industrial demand that causes reserve depletion also spurs additional research to identify potential lithium sources and extraction processes.

> there's no loophole where they'd specifically freeze it out of participating in tender offers.

Again, who said anything about a 'specific loophole'? Needing permission to participate in a tender (which is the only way to sell) is not a 'loophole', and the threat is always there on the table. So again: how was that 'fixed'? Should I interpret your comment as implying that the tender threat of being frozen out is not fixed?

Certainly your fellow OA employee in the other comment doesn't seem to think that it's not on the table, because he is arguing that the threat is fine and harmless because it's never been exercised, which would seem to imply that it's still there...

In a sense, housing suffers from the same identity crisis that bitcoin does. Because so many homes are now being bought for investment purposes and not by resident homeowners, housing has become speculative and the historical slow-but-steady growth in prices has been replaced by a boom-and-bust cycle typical of speculative markets. Just as bitcoin can never become a useful currency as long as speculators dominate its trade, neither can the housing market go back to being the stable economic foundation it once was for the same reason.

> Unfortunately, California is a terrible benchmark. It is as close to ideal for Solar as it gets. Most places are not going to see this kind of performance

There are many place that get a lot of sun. As solar panels come down in price, it becomes even easier to compensate for deficits with additional panels.

It’s common practice to install more solar panel capacity than inverter capacity because panels are rarely operating at peak output anyway. If you’re installing 100kW of inverters, you might install 120kW of panels. The panel array wouldn’t exceed 100kW most of the time anyway.

In a location with suboptimal sun, you might install an even higher ratio of panels to inverter and battery capacity.

Some people get bothered by this because they feel like some of the solar power is wasted at peak capacity, but you have to consider that the inverter and battery capacity is also wasted when you’re not sending enough from the panel array. It’s a balancing act.

You also have to consider that the same sunlight that makes California good for solar also creates additional demand for air conditioning. A location with less sun would have less solar heat gain, which is easier to serve for many reasons.

You've explained it better than I have, thank you. The one nitpick I want to make is the last part, my understanding is that Visa/Mastercard police their perceived brand risk primarily through broad statements that are then interpreted by payment processors in detail. Visa aren't the ones saying "Women having sex on their period is an extreme sexual activity", they're just saying "no extreme sexual activity" and the payment processor has to figure out what that means leading to the former claim.

I was being a little facetious (the sibling said something about Arch, obligatory "I use Arch BTW" reference").

But in the context of GPU drivers, NixOS has all of the same advantages that it does for any other application: once you've got it working it stays working until you change something (and often it stays working even then). For stuff like GPU/GPGPU this is really fucking nice because that is not at all the status quo.

It's also nice that once a piece of hardware is supported well by anyone, that person can share the configuration as a module and it will work for other people, so in a sense it makes Apple-grade "perfect out of the box" experiences realistic on other hardware.

"In California, a "Solar Tax" has been proposed in recent years, which would impose fees or charges on households with rooftop solar panels based on the energy they produce.

Proposals have included fees as high as $700 per year for the average solar consumer. These efforts, backed by Governor Newsom’s Public Utilities Commission, were defeated in 2021, 2022, and 2024 due to public outcry but remain under consideration."

Just admit that the the Democrats in charge of California don't care about the environmental benefits of solar.

I'm in the same camp of the people who like using things forever. However, I find that I'm in a small minority... I am not even talking about clothing, fast fashion etc., people around me are constantly doing kitchen renovations, changing cars every few years, phones every year, etc.

What's the point of building for durability if there's no demand for it?

Moreover, if you look at expensive cars or furniture, the markup on them has to be higher than cheap stuff. Honda Fit is like 20% of the price of a BMW, but I bet doesn't cost 20% to manufacture... So if people wanted quality it would be better for companies to produce more of the expensive option. Either companies are dumb or people don't want quality.

I just recently got a coffee grinder that costs 3 times as much as my old one and it's actually better across multiple dimensions, including material e.g. metal vs plastic . But how many units do you think the plastic junk at 0.33x the price sells vs mine?

>Private equity firms have become more competitive in recent years by recruiting young bankers — freshly trained at a cost to investment banks — months or even years ahead of when they actually join.

When your IB first year analyst is averaging 80 hours per week, like they probably still do, they're not being trained at a "cost" to you, especially since the salaries have not at all followed the workload.

This seems to imply that public discussions about cleaning phones wasn't a meaningfully common occurrence before now.

Agreed. The right terminology used by even the government is "unauthorized immigrants". These include people who may actually be in the country legally - like those seeking asylum - but can be deported at any time.

That said, though no person's existence should be called "illegal", I'm afraid it's an uphill battle to change that term if Fox News is going to use it 24/7. There are better hills to die on.

It's possible that their advocacy is well thought out but not based on the stated reasons. Say, Apple is actually under the control of the NSA and there are hidden back doors in the form of exploitable weaknesses as per Crypto AG. Then preventing the introduction of public backdoors would preserve the value of the current setup where Apple is widely considered trustworthy with respect to their customers.

Lots of nuance, citations below, TLDR is fossil gas and hydro volatility from Russia and climate change has caused price levels seen. Europe avoided €59B in fossil fuel import costs due to new wind and solar in the EU since 2019. The evidence shows renewables have been restraining electrical cost increases, and as more renewables and storage is deployed, costs should remain flat (if not decline).

The great thing about solar is that you can put it nearly everywhere. Avoid the transmission losses and put the panels close to the load, even if it’s not as ideal as one state over.

It’s easy to put extra solar panels into a system to make up for reduced average sunlight. It’s standard practice to have a ratio of PV capacity to inverter capacity of something like 1.2:1. In a low sun location you could bump that up to 1.5:1 or higher.

> The game genie did not give you a menu, you inputed codes which would persistently modify the memory map of the cartridge allowing for things like 99 lives or max Hp. The “menu” you describe was a booklet containing every game and a list of code changes.

Yes definitely, I meant the booklet as the "menu" (just like many restaurants give you a menu that is like a booklet) and decided to call it that so it would be more relatable, but yes it was just a series of codes, but codes you read off the paper similar to a menu (or maybe better, a dictionary or index?)

In Colorado, that’s starting to change, but it’s far from resolved.

Following SB 19-181, the Colorado Oil & Gas Conservation Commission (now ECMC) overhauled many rules. One rule now requires operators to disclose all chemicals used in fracking and in spills, including trade secret ingredients, but there's a catch: They still don’t have to reveal the exact chemical identity to the public — only to regulators and, in limited cases, medical professionals.

Additionally:

The rule rollout has been slow, and compliance remains spotty.

There's no standardized enforcement mechanism to verify what’s actually used on-site.

If a spill happens, the data available to the public is still often vague or incomplete — and trade secret protections can render the chemical list nearly meaningless if you're trying to assess toxicity. (As we've tried, ourselves)

Yes on both halves of that.

Expensive in that the policy choice is "we want the worst-case to be affordable", and that this includes not only explosive meltdowns but also international treaties to make sure nobody steals radioisotopes.

More than it needs to be, because anecdotes I've heard about radiation spills include "some liquid was spilled on the tarmac so we had to dig up a long deep trench; the replacement had some granite in and was more radioactive than the stuff it replaced".

I agree with your points, especially #2, but I wouldn’t call that “instant responsiveness”. Reading the submission title, I was expecting advocacy for favoring UI animations over an instantly responsive UI.

It’s good for a UI to be immediately responsive to user actions, as long as the response matches the user’s intent. So it’s not the responsiveness that is the problem, but the response not matching the user’s expectations.

Fibonacci is a bad example because it relies on the linearity of `prev + current` to be O(1) memory complexity. A lot of divide-and-conquer schemes exploit symmetry and linearity of their internals but if the operation is nonlinear then it requires memoization/caching.

On that note, I really struggle to understand what's special about "bottom up" versus "top down" DP or what categorizes it as unique from any other algorithms.

> a better 8B model with the same spec requirements

It's not the completely same spec requirements though. When using an alloy, you would need to have double the disk space (not a huge deal on desktop, but for mobile), significantly higher latency (as you need to swap the models in/out between every turn), and you can only apply it to multi-turn conversations/sufficiently decomposable problems.
