I haven't seen this mentioned yet, but beyond taste/value arguments, there is an argument that the production of lab-grown meat is not able to reach significant scale with the available technology.

> And yet, at a projected cost of $450 million, Good Food Institute (GFI)’s facility might not come any cheaper than a large conventional slaughterhouse. With hundreds of production bioreactors installed, the scope of high-grade equipment would be staggering. According to one estimate, the entire biopharmaceutical industry today boasts roughly 6,300 cubic meters in bioreactor volume. (1 cubic meter is equal to 1,000 liters.) The single, hypothetical facility described by GFI would require nearly a third of that, just to make a sliver of the nation’s meat.

> If cultured protein is going to be even 10 percent of the world’s meat supply by 2030, we will need 4,000 factories like the one GFI envisions, according to an analysis by the trade publication Food Navigator. To meet that deadline, building at a rate of one mega-facility a day would be too slow.

> By GFI’s own admission, the challenges are serious—current costs are 100 to 10,000 times higher than commodity meat, according to the CE Delft analysts.

> There’s another issue: In focusing on micronutrients as the primary cost driver, GFI may have underestimated the cost and complexity of providing macronutrients at scale. Just like other living animals, cultured cells will need amino acids to thrive. In Humbird’s projection, the cost of aminos alone ends up adding about $8 per pound of meat produced—already much more than the average cost of a pound of ground beef.

Anecdotally, I'd say it has no relevance.
Busting into Grand Central
Yep, (western) people are acting like meat is a human right and a staple day to day food.

My grandparents were the first generation in my country who started to have regular access to meat after WW2. Before that it was either a rare thing and much of the "meat" they ate was offal.

Pea soup was 99% peas and a small chunk of smoked meat added for flavour.

Meanwhile billions of people live perfectly normal lives eating legumes (beans, chickpeas, peanuts) for protein.

And that's why they do it. It's a way of gaining apparent validity by expanding the group for whom you can claim harm.

It goes off the rails when it's only others for whom harm is claimed. That's what makes children such a common trope here. Children will (almost) never say "this harms me". Instead, people get to claim something on behalf of the children, without fear of contradiction. No child gets to say "Hey, I wouldn't mind seeing some boobies."

It's why Greta Thunberg caused such an uproar. She is a child, but got a platform to say, "Climate change harms me". It brought some credence to climate advocates who previously risked sounding like they were doing it "for the children" without the consent of any children.
Digging a hole and lining it with clay and polymer, filling it with household waste, and then covering it with a polymer liner is significantly cheaper than what you are describing.

It's not great, there's no great solution, the problem is hard on multiple levels. If a solution made sense, people would already be doing it.

Hangovers and negative cognitive effects of drinking increase dramatically as people age. I’m guessing you’re 30 or under.

I noticed a dramatic drop in my memory which I attribute to drinking. I stopped two years ago but I’m probably not back to where I would be if I hadn’t been drinking.

Yes, Atlas is extremely impressive. There's a huge difference between choreographed ("do a backflip off the crate onto the floor") and being "preprogrammed" to do everything - it's obviously extremely adaptive or it would not be able to do these dynamic moves in real world conditions, or handle being kicked/shoved around in the way Boston Dynamics like to abuse their robots!

I'm not sure of the utility of Atlas as a form factor though. It's too mechanically complex to ever be cheap or expendable. The humanoid form factor also gives expectations that it should be intelligent, but even when we do eventually figure AGI out, it'll probably be decades later (if ever!) that we get the power requirements down to the point it could be deployed in a battery powered device.
Of course, if you convert that to current value that’s something like £235M at current rates, which seems more plausible (and would have been more like £400M without the self-inflicted damage of Brexit). New cruise ships cost more but they’re also larger and have more amenities, and holding so many more passengers means more expenses for things like furnishings.

I skimmed through the review, it seems it's skewering this book and the arguments it's trying to make.

But curious, if other people see expensive cars as status, me showing up in a fancy car means me showing up with status. If I'm female and I show up with a Louis Vuitton bag, that also means showing up with status, but with a Michael Kors bag? As a female friend told me a few years ago "Ewww, everyone buys that brand, it's now 'cheap'."...

Interesting long-ass documentary about status: https://www.youtube.com/watch?v=t1MqJPHxy6g, but also about the "meritocracy" and the US' idea of "If you work hard you'll be successful" which imply the flip of it: "If you're poor, that means you're lazy".
Hey. Thanks for chiming in.

Did you and the designers have any guidelines or rules of thumb about groove that informed your design choices?

Do you recall any design choices made that had a large impact on the musicality of the instrument? Any neat epiphanies or breakthroughs?

No, but ranks websites with incorrect data higher than others with correct factual data sometimes.
The tax situation also obviously depends on the investors' tax residence. For example in Switzerland, private investors don't have to pay taxes on capital gains. And many countries have a flat tax for dividends and don't consider them income. But then dividends are often additionally taxed at the source, even though you can reclaim it in some cases.

There was Liberty Reserve, Webmoney, e-gold. Even now there's a bunch of sketchy EMIs in Belize and Lithuania like Advcash and Perfect Money. Ransomware before just wasn't highly targeted because "installs" were a lot cheaper and there was lots of other profitable easier scams to run like spamming pharma, FakeAV, etc. An increased amount of attacks like the Colonial Pipeline hack may have coincided with the rise of cryptocurrency but I think it would have happened even without it. There has always been groups that "cash out" fradulent wire transfers for 50-60%, go read wwh-club[.]vip or bhf[.]io if you want to know more (I read these occasionally out of curiosity but there are more "elite" forums out there). Not really any reason to think most of these attacks couldn't have worked with just paying ransom by wire transfers, especially when you consider that after the money has gone through a few countries it is practically unseizable given the amount of time international cooperation takes.

That's the explicit handling of the None case I mentioned in the comment: it causes an explicit, and safe, abort. By "explicit", I mean the .unwrap() call will be right there, in the method that needs to turn an Option<T> into a T, and visible to a code reviewer. In the larger context here of kernel code, it should raise the eyebrow on the reviewer: "wait, this function shouldn't abort, it needs to handle the edge cases!".

(But for some userland app, aborting might be acceptable. The kernel is in a bit of a bind, since an abort — a kernel panic — means the user loses computer until they reboot, and the work along with it.)

Vs. a C pointer … all uses are more or less equally suspect; any given use, you hope the code has done it's homework for ensuring they're not NULL, and if they are, the consequence is UB. (And in Rust, and in the languages Rust steals the idea of Option from, you're only using/passing Options where "None"/null/nil is a possibility. If it's not, or you've verified or handled that at some outer stack frame, then you just pass a reference to a T, which is statically guaranteed to point to a valid object¹.)

¹again, barring buggy code using unsafe Rust, in the example of Rust, or calling into C code that fails to maintain its invariants, etc.

Take the example in the article, where the code does,

priv->mm->mmap->vm_start

while trying to generate the output for smaps_rollup. That's compilable, but buggy, C, because mmap can be null, but we failed to check for it.

Vs., if mmap were an Option<T>, where T is whatever type that pointer points to. Let's say our coder attempts to write,

priv->mm->mmap->vm_start

(In some imaginary language, because C doesn't have Option, AFAIK.) The compiler would say, no, you can't "->vm_start", because "mmap" could be None (whatever you call the "nothing here" value/variant; I'm going to call it None, to distinguish it from the null pointer).

In the case of unwrap, the coder could do something like (this is psuedo-code)

(priv->mm->mmap).unwrap().vm_start

It would then be obvious there is an abort there. Their reviewer would not be pleased with that, I suspect: we don't want kernel panics or oops or aborts while generating a file in /proc. And likely our imaginary coder would know this too, and when the compiler errored the first time, saying, "hey, mmap is an Option", they'd raise an eyebrow, say something like, "wait, it is? When would mmap be None?" and then proceed to properly handle that case. (E.g., by treating it as if it where the empty list.)

Peoples perceptions of number sizes don't change quickly. 1 million will still seem like a big number. It's likely at some point we'll have to re-denominate. There will be a 'new Pound' or something that is worth 100 'old Pounds'.

You can see the number phenomenon today. People still talk about "winning £1M on the Lottery" like it'd set them up for a life of luxury. To reasonably replace even a median UK full-time salary for life you're going to need around ~£700K in assets. That leaves £300K for a modest home somewhere outside of London and the South East. One false move with your £1M winnings and you'll end up back in the office. The £ is worth half of what it was in 1994 when the Lottery started.
I don't doubt that Amazon has abused workers in various ways, I'm just saying the headlines exist because of their massive scale and visibility. EPI estimates (which are probably a bit aggressive, but backed by sources) say of 2.4M workers in the 10 most populous states, $8B/yr are lost to wage theft. Amazon, with about 1M employees, is not stealing billions per year. In fact, they consistently pay well above minimum wage. My point here isn't that Amazon is great and we should stop complaining, but rather that worker abuse is rampant across all industries and Amazon is likely exceeding what is a very low bar.

> Turning this into dichotomy between website operators needing to crusade on government overreach and not using GA has got the be the worst faith argument I've seen in a minute.

Putting words in my mouth has got to be the worst faith argument I've seen in a minute.

> If your local government decides to overreach and find out who's getting abortion pills, Google Analytics will not even be your 1000th biggest problem. ISPs will readily share which sites people visit, the stores themselves will get leaned on, your mail carrier with share where you get packages from.

And it's much easier for website operators to stop using Google Analytics than it is for them to educate their customers on using VPNs and mailing their packages to dead drops (let alone for their customers to actually do those things).

This ain't about dichotomies or the lack thereof. This is about what people can do now to mitigate low-hanging fruit. Nobody said the solution is only to stop using GA; literally all that was actually said is that not using GA is something that the operators of such stores can trivially and immediately do.

That is:

> What do you think HTTPS is going to do when one of these urls shows up in your traffic, email inbox, and a reverse mail address look up leads to one of these?

The existence of problems outside your control does not erase the existence of problems entirely within your control. Website operators cannot force you to use a VPN or a secure email or an anonymous address. They can minimize the data of yours they're sending to third parties.

> I mean did you even read the article?

I mean did you even read the HN guideline specifically prohibiting such a question?
Gave a statistic isn’t the same as linking to a statistic.

Also, statistics include facts like more than average not just specific numerical values.

Yes, in an ideal world your kernel shouldn't have any bugs. We don't live in an ideal world.

Security engineering is the field of practical mitigations - given that there are, in fact, null pointer dereferences in the kernel, mmap_min_addr and adding count limit to kernel oops provides defense in depth to help prevent them from being exploitable.

Chat Interface to Search Engine (www.perplexity.ai)
We've worked on a new chat interface to Perplexity Ask: Available to try out at www.perplexity.ai

The intention is to let people ask follow up questions, and dig deeper into topics. And maybe refine their queries if they weren't happy with the initial response. We are also exploring "concise" and "detailed" answers to each query.

Would appreciate any feedback on improvements to the search, UI/UX, and stuff that doesn't work well yet!
Ah right, the main advantage I have here is that the dev server also stays running when I go to another branch (since it's a different VM). So I can work on one thing, share it with the team and in the meantime continue on another branch. They can see the devserver / running code, while I am working on something else.

It's especially useful for things like migrations or dependency management. In one branch I could work on something that has some database migrations, and then I can still switch to other branches without having to roll back the migrations.

I didn't know about git worktrees though! I'm going to read up on this.
During finals week in my undergrad at Berkeley, I remember seeing the squirrels and thought, "How nice it must be to be a squirrel and not worry about human affairs."

My next thought was, "What looks at Humans in similar fashion?"
That's pretty funny, but not actually true.

I work at a company where we process vast amounts of retailer advertising data, and one of the things we need to do is tag images and extract data from deals. Although humans are still involved in this, at this point they are mostly checking the work of our ML models. This dramatically increases the speed with which we are able to do this - and this speed is one of the things that makes us attractive to our clients.

Didn't get much from the article except that one's relationships are an important factor in happiness. Personally, I found the following paper more actionable: "If Money Doesn't Make You Happy Then You Probably Aren't Spending It Right"[1].

> The relationship between money and happiness is surprisingly
weak, which may stem in part from the way people spend it. Drawing on
empirical research, we propose eight principles designed to help
consumers get more happiness for their money. Specifically, we suggest
that consumers should (1) buy more experiences and fewer material
goods; (2) use their money to benefit others rather than themselves;
(3) buy many small pleasures rather than fewer large ones; (4) eschew
extended warranties and other forms of overpriced insurance; (5) delay
consumption; (6) consider how peripheral features of their purchases
may affect their day-to-day lives; (7) beware of comparison shopping;
and (8) pay close attention to the happiness of others.

As a board member of an organization that was benefiting from Amazon Smile, this is just the lamest set of excuses I've ever seen. Amazon should have said: "We're cutting this because we don't want to maintain it, it hasn't been staffed, and isn't focused in our core business (making money)"

> People who really really want the product get it at a fair price (they were willing to pay).

If people were content to get the product at a fair price, scalpers wouldn't be a problem in the first place. The whole reason scalpers are considered a problem is that people want the product at a cheaper than fair price, and scalpers prevent that by buying up any inventory that is being sold for below the market rate.

Basically, if companies employed the strategy you suggest, then they'd effectively become the scalpers in the eyes of people who consider scalping a problem, with all the PR issues associated with that.

That's not to say it's necessarily a bad idea though. Once you accept the fact that scalpers exist, it makes sense for companies to capture those profits themselves rather than let scalpers just have them for free.
