>Many dentists, having seen what life was like before fluoridation, have no interest in returning to the pre-fluoridation era of widespread cavities, abscesses, dentures and people in pain.

Is that really true? I live in a country without drinking water medication (thank god) and it's not such a horror story as this article makes it sound. I know that dental health was worse in the past and has improved since, but it doesn't seem to be due to water fluoridation but rather other advances in dentistry and personal dental care.
Security is as important to most executives as toilet tissue expense. If the consequences are minimal, so is the urgency.
Mandating a lower-than-maximum container stacking height was itself a buffer, which is now being filled by temporarily stacking higher.

The idea that we run without buffers in the supply chain is contradicted by his own big idea to use one of them.

We don’t have big warehouses full of inventory sitting around like we used to, true. But we do have the money we generated by running more efficient supply chains, and money is more flexible than outdated inventory.

Edit to add: whether that money is sitting with founders, shareholders, or employees is largely irrelevant from a macro perspective.
Assuming no other conditions change, how long will it take them to use up the extra storage space?

I could really care less, but as a developer I'm not buying a laptop without Vulkan support. It's a little silly that Apple can even market it as 'Pro' without support for the graphics API that pros actually use.
This might be the nicest thing I’ve ever said about Comcast but I think their slow roll-out approach was better (from a PR perspective) than what facebook is doing. There was no big bandaid pull where Comcast was suddenly Xfinity it just sort of... happened?
In theory if you value variety of experiences than 5 years as junkie may be better outcome than the a desk job.

Most people don't value variety all that much which is why 9-5 workers are lot more common than perpetual travellers etc.
There's a U-shaped curve for all cause mortality with cholesterol levels, just like anything else. Cholesterol is not bad, it's literally the building block of steroid hormones, vitamin D, etc.

Similarly, there's a good argument to be made that most people actually eat too little salt. If you compare most sodium guidelines to data of sodium intake versus all cause mortality, you're more at risk of death following the guidelines.
The obsession with RoE is really just a major form of efficiency. Having things sitting around unused is a huge reason that US car companies got their asses handed to them by Toyota and their TQM/LEAN system they developed.

People writing articles like this forget that it's not just Wall Street, but competitors who created the huge pressures for adopting JIT inventory systems. There's also the consumer. Are you willing to spend the additional money required to buy a car from a company who wastes tons of $ on excess inventory?
> 2) Having the X server, window manager, and compositing engine in separate processes introduces latency due to context switches on the hot path. Wayland fixes this by making the display server, window manager, and compositor all one process.

That also mean that you have a single process that if it crashes you loose your entire desktop session crashes. In the old X days I used to have my compositor crash a lot of times (good old days of Compiz with a ton of effects), but everything else was still functional, and I could simply restart it without loosing my entire desktop session. Or you changed the settings on GNOME, in the past just restart the WM, with Wayland of course you have to log out and login again.

Also, things that on X were simple (for example having an application that captures the screen) are difficult in Wayland, and the only way to do so is to incorporate that functionality into the window manager itself, that becomes a monolith very quickly.

Speaking about latency, to me is stupid. Like I said, in the old days of Debian 6, with a core2 and integrated graphics I used to run GNOME 2 with Compiz, I had smooth graphical effects and it did run fine, with a memory usage less than 100Mb in idle.

Nowadays we have hardware that is orders of magnitude faster and we have more problems that back in the days we didn't.

Seriously, it's looking like he pretty quickly is looking to start an influence/propaganda channel.

Following the exact same playbook. A bunch of easily agreeable "Rah, Rah bad Wall st. Short term over long term bad" to get everyone nodding, then an incredible leap to push his actual argument.

This guy is falling very quickly from "interesting how he got that thread picked up everywhere", to "somethings fishy here".

> the pay is so high because otherwise no-one would go work there

This is a meme; every other tech company that's remotely competitive in terms of compensation pays similarly at the corresponding levels (across the entire ladder). Even if you want to rule out every single social network and ad-tech company (which is also a meme, but for the sake of argument), you've got plenty of uncontroversial options like Netflix, Roblox, Doordash, Dropbox, Square, Snowflake, etc. Also a ton of late-stage pre-IPO startups (Stripe, Instacart, Databricks, etc.)
I can't figure out if Zuck and the rest of Facebook leadership are actually bought into the whole metaverse nonsense or simply using it as a distraction from the current image issues for the brand. Facebook is and always will be a data collection and advertising company. No amount of VR side hobbies will change that.
It would impact Apple's ability to raise money on the stock market tho.
They<the package maintainer> ≠ They<the committee>
The components in the early iPhones were all commodity off the shelf parts. That’s one reason analysts thought Apple could never maintain its technical lead as other companies could easily replicate the tech. They didn’t factor in the sophistication of the software, but that couldn’t necessarily hold indefinitely.

Since then Apple has invested massively in premium components, in many cases helping develop breakthrough new tech. Their CPUs are the best known example, but take retina displays. Apple helped develop the tech with sharp, and invested heavily in it to guarantee exclusivity. They actually owned the manufacturing equipment operated in Sharp factories. They sunk huge resources on long term contracts for flash memory. They bought small tech companies with unique optimisations, like an Israeli company with ultra efficient flash memory control circuits. Thev’re had a very long standing close partnership with Sony on the camera modules. Early iPhone cameras were only mid range catalogue parts, but for a long time they have been unique custom designs to Apples precise specs. Face ID is enabled by unique miniaturised 3D scanning tech. They’ve gone from generic gorilla glass to ever better refinements of the tech that wouldn’t exist without their patronage.

All of this has not come cheap. The point is to create a massively deep and wide technical and capital moat between iPhones and anything else on the market. It’s a very deliberate long term strategy that’s been running for well over a decade.

Higher component prices are a strategy, not a burden. Pitching this as ‘rising costs’ that are putting them ‘under pressure’ is industry analysts yet again looking at what Apple is doing and boldly leaping to entirely the wrong conclusions.
I grew up in Germany in a household that never used nasal decongestants, probably out of some fear that they might be dangerous.

When in Canada a doctor told me to buy some pseudoephedrine pills to treat a clotted ear and I found the experience so nice, that when back in Germany I walked into a pharmacy to get some.

The states without income tax tend to have consumption taxes that are much higher to offset them as well as property taxes. I've lived in two of them (WA, TN sans dividends) and study after study shows the poor in those states along with NV and TX are some of the worst off compared to states with income taxes because they share a disproportionate funding into state coffers compared to other quintiles when compared to states with modest income taxes. This isn't to say things are great in WV and Mississippi everywhere, but there's some commons trends across very politically different states only joined by lack of income taxes.
Future Synthetic Drugs of Abuse (1988)
I see a lot of discussion assuming the patent covers "putting an ad on a tray." Claim 1 of [1] says (when you see the word "said" you can just replace it with "the" -- it doesn't become any more legal just because it has "said")

A method comprising:
positioning a first tray cart containing trays at the proximate end of a scanning device through which objects may be passed, wherein said scanning device comprises a proximate end and a distal end,
removing a tray from said first tray cart,
passing said tray through said scanning device from said proximate end through to said distal end,
providing a second tray cart at said distal end of said scanning device,
receiving said tray passed through said scanning device in said second tray cart, and
moving said second cart to said proximate end of said scanning device so that said trays in said second cart be passed through said scanning device at said proximate end.

There are 14 dependent claims, all depending from claim 1. We don't see anything about "advertising" until claim 4.

If you knock out claim 1, then all the others fall as well. I won't even try to defend claim 1 -- if you're saying "how else would you do it?" you're on the right track).

Metastasis: A pathogenic agent's spread from initial site within the host's body
It's fallacious to suggest that 10% capacity everywhere would have abnegated the supply chain issues.

That said, shipping in particular is problematic in how they externalize costs. They can get away with shenanigans because they use international loopholes etc..

I say we need to dump this 'flagging in exotic country ABC' and require that any ship landing in country ABC has to abide by all the regulations of ABC.

Keeping tons of spare capacity is neither economical nor environmentally friendly. Also, it would probably only shift the problem elsewhere.

* There some things that are people simply need for survival. At a certain point, having no spare capacity and cascading failures means people die. Lack of masks last arguably killed people last year.

* It's quite possible to excess capacity and be good to the environment while present production is often terrible despite the lack of excess capacity.

* Sure, a complete lack of excess capacity is economical. Which is the OP's point in different words. Robustness to failure has been traded for immediate returns.
> This isn't something accounting practices or "less greed" would solve

Are you seriously trying to say that production being moved to China, et al. is not because of greed generally, and ROE specifically?
They also mentioned how this could happen at the end of the article.

But New York also has a subway system that (approximately) everyone uses to get around. That turned out to be a perfect spreading ground for a respiratory virus. If I understand correctly, that's a big part of why New York got hit so hard. You can't just pin it on Cuomo's criminal irresponsibility.
I mean fluoride is one of the most interactive elements on the periodic table. It’s pretty clear it interacts with the body in pathogenic ways. That’s part of the reason why it bonds to the enamel of the teeth so well.

I don’t think we need to supplement tapwater with fluoride now that toothbrushes and toothpaste are so widely available.

You can’t control the dosage since people can drink as much tapwater as they want and still do not know how much they actually are receiving.

That being said I highly recommend everybody get a reverse osmosis water filter. Add in some electrolytes and you’re good to go.

Edit: Never mind, I was wrong. Fluoride isn't an element. It's somewhat reactive, but not nearly as much as Fluorine.

> And if you've got today's top end VR rigs, it's sorta obvious that the world is going to go this way - it's too good, and productivity is enhanced on the level of "bicycle for the mind".

How exactly? VR is just a display technology, with no new input methods that are even remotely usable for anything like games. How am I going to be better at programming by wearing a VR headset and typing on my keyboard than looking at a screen while typing on my keyboard?

How am I going to be more productive when forecasting prices in Excel on a VR headset than on a screen? When drawing the layout of an integrated circuit? When summarizing news or books?

Sure, it will be easier to visualize a few 3D models, and remote meetings will feel much more natural in VR, but the vast majority of work essentially boils down to either manual work, text manipulation, or fundamentally 2D models.

Unless and until someone comes up with a revolutionary input method with the precision of a mouse and the flexibility of a keyboard (like they did with the touch screen for phones), I don't believe in any claims of a revolution through AR/VR. Only incremental improvements in specialized fields.

> I don’t understand the title? How do you get ‘rejected’ by Code Academy? It’s not a ‘boot amp’ with an application process. You either do the free lessons offered, or pay up for one of the ‘Pro’ level tiers.

From his blog:

> I've applied to work at Codecademy three times, once in 2014, again in 2015, and most recently in 2020. I've been rejected all three times. I wanted to prove to myself I was capable of building something like it, so I decided to build my own version.
Yep. It's why I switched from Vyvanse (lisdexamfetamine - basically just d-amp bound to lysine which is then metabolized into d-amp during digestion) to IR generic Adderall (a mix of d-amp and l-amp).

Any unwanted effects (insomnia if I take it too late, etc) are almost entirely due to the l-amp, but the slow release of Vyvanse made it essentially impossible to titrate and my options were either to take a dose so low it wasn't effective or deal with regular insomnia due to lingering amphetamine effects into the evening.

I guess ideally I'd have IR d-amp but I assume it's considered too "abusable" so it's rarely prescribed. Meanwhile, my whole goal is to get useful effects without taking enough to feel like I'm tweaked out or high.
Ask HN: Parenting Advice
Hi HN, this might not be the right topic for this forum. But i thought i will ask anyways, before I go get chewed out on StackOverflow or Reddit. our son who turned 13 was diagnosed in the Autism spectrum when he was 4. Fast forward he has grown up to be an extremely smart/capable mostly polite individual with some OCDs. His obsession with a topic sometimes drives him to extremes and he likes to keep on discussing his favorite topic despite the opponent having given him sufficient social Cues that they are ready to move on. This upsets him real bad. Resulting in tantrums, throwing stuff, verbal abuse. He is getting home-schooled for the most parts by his mom and me, and goes to a homeschool supplement only for social interactions. I can only imagine how that is coming along for him. This behavior is starting to impact myself and my wife.

But I wanted to request for specific tips from dads out there with teenagers with anger management issues(usually an autistic trait but neurotypicals also share some of these obstinance traits). How does one defuse a potentially volatile situation and better yet how do You engage with them without provoking them? I like having these discussions with him and am open to them, just not for hours together. And any good resource on general parenting tips(books, Youtube videos/talks) are much appreciated.
It’s an accessibility lawsuit waiting to happen, as a large portion of the general population gets motion sickness wearing goggles.

AI audio descriptors may come in handy, but really I’m more concerned with excluding people based on cost of hardware and access to high speed internet.

Not at all. More educated people tend to be more anxious and more depressed.

https://www.originsrecovery.com/wp-content/uploads/2020/10/H...

The fact that we trust those more prone to depression to solve depression should not be discounted.

When it comes to 'dysthymia'. The only reason we find it to be a disease is that we expect people to be happy all the time. We've labeled anything other than that as diseased. As I stated elsewhere, I do not believe in happiness. Most of my day is spent neither sad nor happy. Were I to be sad all the time, I don't think that's particularly interesting either. Our society is not set up with space for people to not be happy. Society is ill, not the people.
With shipping containers being sent back to Asia empty rather than taking an extra leg to mid-America to fill up on US farm products to sell in Asia, is the price of soybeans and corn in Asia going to spike soon?
Absolutely. In fact, just gluing a $30 flight controller + servos/motor to a foam board can work [1].

But they are still maintaining it. Also, the improvements that Wayland brings are not really specific to them, because they are mostly due to a new Linux kernel feature that is KMS, and you can use libinput also with X.

I don't really see the point of Wayland, to me X was just fine, sure, maybe it was time for X12, but was a completely new display server needed?
By the sounds of it they just want robots.

What? If this is manipulation then I'm a manipulator as is every other parent (and teacher, and every customer service worth their salt) aren't we?

Yep, we simplify. Yes, we tell stories. We don't lie. (No, teaching Newtonian mechanics without mentioning Relativity isn't a lie, and neither is simplifying the container explanations until even bureaucrats can understand it ;-)

That said, having

1. seen the email that circulated with my customers ten years ago about how container ships transport goods from Asia to US and American air back

2. and having recently listened to "The Goal" by Eliyahu M. Goldratt

I do wonder if this is really the best solution.
Post-Snowden, the lesson is the NSA is doing their damnedest to watch American's activities online. I would bet money that they're doinf everything they can to watch Cloudflare, despite no direct evidence, because of course they are.
It really depends on the game. I was playing H3VR, and definatley experienced that dreadful isolation feeling as I was out in the middle of nowhere surrounded by fake unliving things. But in multiplayer games like Onward Its provided the opposite feeling for me. My wife and kids left for a week, and I work from home... after a few days, it felt like hanging out with friends.
Containers have a lifespan, so China has always been making containers. When containers don't come back you can buy a new one. Shipping them back empty is a lot cheaper than buying a new one, but only if you can get them shipped back. The price to ship a container back empty is low enough that some ships decide it isn't worth it.
Rules and heuristics built for normal times and a specific set of expectations and constraints fail when those expectations and constraints are no longer valid.

Odd, that.

In my household, we started making our own pizza, from scratch (save canned / bottled Pizza sauce). Flour keeps and is shelf-stable. Most toppings survive refrigeration. Those best served fresh are bought as available, menu rotated as needed.

If your supply chain can't guarantee delivery of complex sets of fresh time-sensitive product, drop constraints such that the product mix is less time-sensitive. Sourdough substituted for dry yeast, unavailable at any price.

(This works well at the household level. It works less well at industrial-scale production where flexibility is greatly reduced.)
