In his defence: he's been working on C++ for 44 years now. Or to put it different: he's been working on it from the age of 28 to 72 today. It's a huge part of his professional career, and his life in general.

People are emotional creatures; I'm sure Bjarne is no exception. I find it hard to fault them too much it, especially as I'm not so confident I'd do any better in similar circumstances, and I've seen others do a lot worse under similar circumstances. C++ isn't going to vanish any time soon no matter what, so it's good people keep working on it – a few misguided comments here or there? Meh.
> I'm sure they won't be paying Stripe the standard 2.9%, but still--what value does Amazon get out of this?

These deals are priced on a cost-plus basis. Amazon might pay Stripe the cost of the underlying network fee plus .1% or half of cent.

Stripe negotiates fees with leverage.

note Stripe is publicly commuting to AWS in this announcement. It’s likely that the exchange here is “we use you for payments and you commit to $Xbn in AWS spend.”

Similar to MSFT and OpenAI. We give you billions, you spend it right back on Azure.
I agree to extent; but one issue is that there should be a small amount available for research purposes and places where it is required.

For example, containment of certain chemicals is pretty much impossible without Teflon.

Chlorosulfonic acid is one of them.

Also, if you're working with this chemical, it may be useful to make mixtures of PFOS, PFBS, etc in order to process other products and not have highly reactive situations (effectively 'explosions').
Obviously these should get out of the facility they are contained in to pollute waste water or anything else, and should be used in a way that they are recovered and recycled for use over and over - much like what the authors are suggesting to do here.

Of course it obviously doesn't work perfectly that way, and things like this also introduce pollution as well while cleaning the water. So of course this should only be applied where there is a chance that they can remove more PFAS than they introduce to the system, which may not be as universally applicable as we may think.
Please don't ignore that most of these regulations exist because builders will do whatever they can to profit as much as possible, generally to the disadvantage of the buyer that is typically ignorant of the risks of a home.
Google recently said they are recalibrating the level of risk they're willing to take with releasing this technology. OpenAI's CEO responded saying

> "recalibrate" means "increase" obviously.

> disappointing to see this six-week development. openai will continually decrease the level of risk we are comfortable taking with new models as they get more powerful, not the other way around.

How does this resolve?

OpenAI not releasing something isn't going to stop Google or another player from releasing it. Won't they have to recalibrate too or be overtaken? Pandora's box is already open.
But even if you have the set of all reals not describable with a finite amount of symbols, I can still imagine what happens e.g. if you multiply all its values by 2, or what the cartesian product of this set with another is like. At least, I can reason sbout that result in a way that's not worse than reasoning about the set itself. Using axiom of choice on it does not make things harder than the set itself already is

Humans were not evolved to resist these kinds of poisons. Nothing like this exists in nature. It’s an extremely potent chemical.

No, it didn't. That's "sterilizing immunity", which is a feature of some but not all vaccines. Flu shots, for example, have never given full immunity to the flu, but they've always been vaccines.

> Disney is amazing at making content

Are they? They're certainly good at buying IP that people like, and now they own a big back-catalogue of beloved franchises. But the vast majority of content they pump out these days is mediocre at best. They own so much that if you want to go to a theatre to watch a movie, your pickings are essentially all owned by Disney. They generally make money but it's because they bought everything.

I can definitely think of more Netflix originals that I've enjoyed in recent years than offerings from Disney's zero-risk, safe, predictable gray goo.

Just a quick guess I am pulling out of my ass.

Did somebody high up do a cost analysis/breakdown that said: is this entire business org making the company money or can we just use Stripe for less money?

Does it boil down to that gross oversimplification or not?

I'm sure it isn't easy to quantify the intangibles (if there were any) on what edges Amazon had over Stripe and benefitted from by choosing to do it in house. I'm sure it might not seem like an apples-to-apples comparison, but I guess when you zoom out high enough (company spending $X money in, getting Y out) it's comparable to any other purchasable good/service?
It's sad because it's not hard to pick a name for a project that isn't a swear word.

In short the built quality is horrendous, at 16k miles there were so many rattles and squeaks. Acceleration is amazing. The suspension is equivalent to a track toy that bounces on every bump. Tesla removed ultrasonic sensors in 2023. The autowipers are complete trash. The sound isolation is extremely poor. Driving the car gave me a headache.

So, I won't be buying it. I can't believe how harsh the suspension is. Also, the cabin is really dark at night, as there is 0 mood lighting.

Hi HN, author here and happy to answer any questions :)
I just changed a filter in my air purifier after having it next to the kitchen for about 6 months. The prefilter was covered in a layer of cooking oil mixed with dust. The built in air quality monitor always shows poor air quality wheen cooking. Its no joke, especially in places that have poorly constructed/cheap stove ventilation.
The phone compass often works poorly near magnetic metal (which is… often). Once you start moving it will calibrate itself, but that can take a block or two of moving in a straight line in an urban area.

Mounting your phone on the windshield helps with GPS some, as does getting a newer phone with L5 GPS.
Wind power generation does not, in fact, require any rare-earths at all. (And, they are anyway not rare.) You have asserted this falsehood, and been corrected, many times before. Please do not repeat this falsehood again.

Copper is used heavily in all electric power systems, so does not count against any. Likewise, all industrial energy infrastructures depend heavily on mining, less-electric ones most of all. So, please do not throw up this irrelevant canard again.
Most of the contractors who like to talk about the good old days are simply spreading FUD. New homes will hold up better a hundred years from now, and have a much lower chance of catching on fire, collapsing in an earthquake, and are less harmful to the planet since they use a fraction of the energy.

- Old windows from 100 years ago were single pane. I grew up with them. My bedroom was freezing cold in the winter and roasting in the summer. And they couldn't seal so they leaked water which rotted out the window frame. Not exactly a great example of old homes lasting longer.

- Cedar shake is a fire hazard. Yeah, we don't build houses like that because a century ago entire towns would light up like a match. It was a regular occurrence.

- New constructions (At least mine was) built with 2x6, so it has a higher R rating and better soundproofing. My energy bills are a fraction of those for an older house.

- New homes are better sealed, and contain air tight vapor barriers. Water can't get in and rot the wood like with old homes. Yes, it's not old growth wood, but it will last longer. Better sealing, air filtration and HVAC will reduce your chance of getting lung cancer from air pollution.

- Modern high end LVP flooring is substantially more robust than hardwood. Dogs can't scratch it, you can drop a cast iron pan on it, it's waterproof. If you want to instead spend money on hardwood there's nothing stopping you, but LVP looks great and is easy to replace.

I think you assume folks want to check out of life because they think fentanyl is a better choice, when instead fentanyl makes folks check out of life.

Not so much with the other three links, but if there was content in my school library as porny as the stuff in that first link, I really wish someone had told me about it so I could have checked it out. Sure I had the Internet by high school, but desktops ruled the world back then, so that content wasn't terribly portable.

I am against this sort of censorship, especially when imposed externally on a district, and don't even necessarily mind those exact books being in a high school library, but, like... I also don't remember any graphic novels depicting even straight sex in that kind of way, in our school libraries, just un-sexy sex-ed-book or encyclopedia illustrations and such, and I don't think there were even that many of those—I do get why the presence of that content in schools might surprise or alarm some folks.

My advice is to first define the importance of support and how many tickets have to be solved within a specific time period in % (with your manager). Then define a part of the team that works on tickets for one sprint (alternating). This worked pretty well for me.

Example:

Your team has 6 members
Your management would like to put 15% of the workload for support
Every sprint 1 alternating team member is doing just support tickets
You keep track of the support days of every member to equalize the workload (support is no fun)
Because working alone is not the best situation you could work with 2 members every two sprints, but keep in mind that this means NO support ticket is solved for 1 sprint

This is the best solution I could find being forced to practise SCRUM - even if it does not match the rules exactly.

Wake up at 8. Coffee, possibly oatmeal/toast or other simple breakfast. Daily standup at 9 or 930 depending on the day of the week. Shower. Walk to cafe or drive to library. Start work around 10 or 1030. Lunch break around 1230 or 1. Work until 5pm or so. It's a bit flexible depending on workload.

I mean I recognize that definitions are squishy and this thread started with a dispute of the official definitions in the first place. But when I think "rural" I think of the actual countryside (of which there is a lot in the US), not a population center with the density of some cities here in NJ.

To pick a random example for contrast, something like Hudson, Iowa looks a lot more like what I think of as rural. Which is also a small place people live, but unlike Sibley it bears little resemblance to an urban core.

I don't think this is due to illegal aliens, without which our construction industry would be in even worse shape, but rather that there have been massive declines in the competence of domestic workers across the board, and this has been hidden by outsourcing, importing skilled workers, and technological growth (e.g. have machines do things that domestic workers cannot), so that you see productivity declines in those areas where you cannot outsource and you cannot pay extreme wage premiums to attract people with basic reasoning skills.

You can see this literally everywhere. Unless you are going to pay 200K+ you will have difficulties hiring reasonably intelligent, motivated, conscientious workers.
Legalize everything and produce it pharmaceutically, and this problems pretty much disappears.
I said systems which are stable are not corrupt, as found in abundance in nature, not that nature does not include examples of what happens when a system becomes corrupt.

Population density breeds disease and parasites (of the biological kind.)

Population out of balance with resources is a systemic corruption that living strategies resolve dynamically through time.

Not storing media sounds odd (prone to linkrot), but I guess this feature is likely optional?

I'm not an expert but the SSB scaling issues seem related to the architecture being tied to the sigchain, & general feed immutability. This makes it very difficult for pubs to, for example, accept/process subsets of posts or do anything out-of-order. It also makes it impossible for clients to limit local database storage, especially mobile clients where that might be at a premium.

Even just the existence of ephemeral notes seems to indicate there's no such architectural limitation so that sounds really hopeful.

On one hand, I get the concern about this because mechanical clocks still exist, familiarity informs me that they're easy to read, and nostalgia tells me they're important.

I would do that the hacker way:

- build the current TeX.jar

- jar tf TeX.jar | grep whatever to get a list of to-be-renamed classes

- use sed or manual editing to generate a large list of recipes

- run those recipes

Instead of jar tf, grep for “^package foo.bar.baz” and “class (complex regex)” in the source code to get a list of package and class names, or use the directory structure. Maybe do all of them, and compare the results for robustness.

That list will be large and it may not go perfect in one go, but it’s a one-off job, and you‘ll get there.
Like many others here, rather than answering how to make it work, I would say the premise is not valid - scrum isn't the right tool for devops. Probably something more akin to Kanban should be looked at.

I find both your parent and your comment to be the obvious answers for why "productivity" has dropped. People are probably just as, if not more, productive. It just takes more work to complete a single house/office/job due to both worker safety and building safety.

Having some experience in the field, the idea that migrant/undocumented/illegal/etc workers are spoiling the workforce is pretty absurd (as is suggested in a few other comments). There were plenty of terrible workers that I knew to be or suspected to be in that category but the rate that they were bad was no different than anyone else.
> Differences in emissions for each meal are influenced by two key factors: the overall quantities of food waste and packaging, and the supply chain structure.

Meanwhile, grocery meals have less packaging per meal but larger quantities of food must be purchased, leading to higher household food waste. The two meals also exhibit inherent differences in supply chain structure, particularly with ...

Their main premise is that food waste dominates the packaging contribution.
