The idea is that you could ban any set of "unhealthy" inputs and give the big food companies some time and they'll come out with something just as unhealthy that complies with your rules.
The underlying issue is some mix of what industrial processes make possible combined with food scientist working with taste test panels to hyper optimize food. When you spend all this time and effort trying to create a snack where people are always left craving just a bit more you end up with the kinds of junk food that we have.
We want there to be some simple answer of "it's these ingredients, or this specific combination" but the actual answer seems to be that when you use industrial processes and science to min-max cost and palatabillity you always end up with junk. Whereas when you cook food with typical home methods and ingredients you don't.
Food health science has always had difficulties with just how complicated the actual processing of food in our bodies is and the more we look the more complex it gets. But the "ultra-processed foods" test seems to be working out as a successful heuristic to identify especially unhealthy foods. Given the issues health science has had with coming up with exact answers a heuristic that's pretty reliable (even if imperfect) is a pretty big win!
If the goal is to regulate unhealthy foods then it does kind of have to be perfect (very low false-positives). UPFs as they are defined include baby formula, many frozen meals regardless of macros, soy/almond milk, instant oatmeal, pasta sauce, flavored yogurt, etc.
Invariably when someone says something like "UPF is a pretty reliable heuristic" its because they are massively underestimating what counts as UPF and using a "I know it when I see it" approach, which, yeah of course it seems reliable if you start with the precondition that UPFs are unhealthy.
If it's just guidance and not for regulation, well, you have similar problems in the opposite direction. prepackaged whole grain bread is UPF the same as Wonder Bread w/ 2.5g added sugar per slice. It's easy to say "just buy fresh bread" but when that collides with the reality of a busy schedule then UPF designations become next to useless. The undeniable value that preservatives have for healthy and unhealthy products alike mean that anyone using actual UPF as their heuristic will be completely rudderless.
>the actual answer seems to be that when you use industrial processes and science to min-max cost and palatabillity you always end up with junk. Whereas when you cook food with typical home methods and ingredients you don't.
That's not an answer at all. You need to explain why an industrial mixer would create less healthy food than a kitchen mixer. The scale shouldn't matter.
As far as different payment systems go I think gnu taler is the most compelling. If keeps the payer anonymous while letting the government know how much the payee received for tax purposes.
I'd add that we also chose policies that made housing expensive. It used to be much cheaper to live in NYC for example, but housing options included what was essentially a dorm room with shared facilities. Those were outlawedes for various reasons. There are also a lot of other policy factors that push up housing prices.
Cheap housing isn't a panacea, but if there was sub $500 dollar rent in NYC you'd see a lot less homelessness.
Single-room occupancy (SRO) housing was effectively outlawed by tenant protection laws. The only way that housing with shared facilities can possibly work is when the landlord enforces strict rules and immediately evicts tenants who misbehave by making a mess, hassling other tenants, or not paying their rent. But in many cities it can literally take years to evict a tenant, and the city will even pay for legal aid for the tenant to fight it in court. This reduces rental housing availability and increases prices for everyone.
Idk about NYC but the people I see on fent in west coast cities’ homeless encampments couldn’t pay a $500 rent any more than they can the $5,000. They’re strung out all day long and can’t pursue any goal besides getting more drugs.
On the other hand though, a lot of who’s technically homeless at any given time aren’t that chronic, mostly hopeless, and very visible set. It’s people who did lose their apartment just barely after an unexpected job loss or medical expense. Those ones could be helped by cheaper rent! But that group isn’t very visible, doesn’t bother anyone, and often couch surfs, sleeps in their car and showers at the gym for a couple months, etc. and most importantly, they use the many safety net resources to get back on their feet (getting a job usually).
Most homeless people aren't born homeless. Maybe at the point they're at now, yeah, a $500 rent and a $5000 are equally inaccessible.
But for the people on the edge of homelessness, that $500 rent could be the difference that prevents them from going down the death spiral of homelessness, lack of options, drug addiction, etc.
To support your point, we’re talking nonsense when we use the word “homeless” to describe all the different types of people who can fit that definition.
Doing that masks the fact that there are working people with housing insecurity, by putting them in the same category as emotionally disturbed drug addicts.
In every analysis I’ve seen, poor people with housing insecurities outnumber the mentally ill type homeless people by three or four to one. It’s very possible to help them, but very difficult to talk about it because everyone imagines you’re talking about the other “chronic homeless” type.
I had a wild conversation with a co-worker who was here as a Ukrainian refugee where he was asking wtf was up with all the homeless people. He was legitimately baffled that they are poor and at war but still didn't have nearly the same level of problem. What was funny is he described what amounted to a soviet version of an SRO being pervasive and I was like "oh those were outlawed and torn down in the 50s"
I think the confusion here is that Signal does in fact encrypt the notification in transit [1]. The FBI had access to the user's unlocked iPhone and went through the notification history on the device. The issue the user faced is that even though they deleted the signal app they were unaware that iOS (and Android by default) retain a database of past notifications even after they're dismissed from the notification pane.
[1] Well actually they just send a blank notification, the signal app then reaches out to the signal server for the actual encrypted message content when it receives the empty notification.
1. On android if Google Play isn't available (or you install the no Google apk version) it'll use a websocket for notifications. Apple doesn't allow a persistent connection except through their own notification framework.
2. In either case Signal doesn't send message contents through the notification framework (not even encrypted). Once Signal receives a notification the app wakes up and reaches out to the signal service directly for actual encrypted message.
3. Regardless when signal shows the contents of your message in the notification menu of your device your device keeps a record on your device of that message content.
The FBI here didn't get anything from apple, once they had the apple device unlocked they looked at the notification database on the device to get the message contents. This isn't really any different from the fact that if the FBI has your unlocked phone they can read your signal messages. The notable bit is that the notification database retains messages even after the app is deleted.
" if the ___ has your unlocked phone they can read your signal messages. "
It's worth noting you can add an additional security check pin/bio/pass to signal that is different from your phone unlock.
The protester had also uninstalled signal from phone (even with access to the phone, they would not have access to signal, if they had reinstalled signal, and some how got the security pin or passphrase, they wouldn't be able to load the prior messages, without either, no messages at all).
> Apple doesn't allow a persistent connection except through their own notification framework.
How can iOS not allow persistent connections at all? How would a long download work or a call in the background work at all?
> Regardless when signal shows the contents of your message in the notification menu of your device your device keeps a record on your device of that message content.
How is that not treated as a backdoor unless it's explicitly mentioned when someone installs iOS?
1. I'm not an iOS dev, but I know they have a specific framework for doing calls (CallKit I think), so you'd be using specific APIs that allow for a persistent connection for that purpose. Probably something similar for downloads. But generally iOS kills apps running in the background after a while so there's no way to persist an open connection indefinitely.
2. To be clear it's my understanding that the notifications weren't exfiltrated off the device. The notifications are stored in a database on the device that iPhone and can only be accessed by unlocking the phone. So I wouldn't call it a backdoor. Both Android and iOS retain notifications in a database, in Android you can disable it, I don't know about iOS.
> Make 20 year experiments before rolling out any change at scale?
Basically. It wouldn't require a 20 year experiment probably. Looking at whole words vs phonics as an example, you'd get a handful of schools to participate and they'd try phonics in one class and whole word in the other. By the time the kids were in 2nd grade the fact that whole word learning wasn't working and that a higher rate of kids needed remedial lessons to catch up would have been obvious. And if it had worked really well you'd expect to see that performance improvement in reading by 2nd grade too!
So the experiment would take 3 years. Though then you'd probably want a larger scale experiment. I'd think if things were going well once kindergarten finished you could probably start involving more schools in the experimwnt the next year. So like 3-6 years altogether.
We have been successfully educating kids for a long time; if we want to mix things up with some fancy new pedagogy we should absolutely be studying if it actually works before rolling it out at scale!
This seems like a corruption of "you can't have your cake and eat it too." I'm somewhat confused as you can definitely both bake a pie and eat it too. Or are you trying to make some kind of point that I'm missing?
Have you looked at Bluetooth LE Long Range? I believe more recent phones have it and it claims communication of up to 1km. In practice less in the woods I'm sure. Still a dramatic win over standard Bluetooth though.
BLE Coded PHY is on my radar. The theoretical range boost is huge, something like 4x over standard in ideal conditions. The challenge right now is that flutter_blue_plus (the BLE library I'm using) has limited support for negotiating Coded PHY, and both devices need to support it. But phone hardware has been shipping with it since around 2020 so the install base is there. Definitely something I want to add, probably as an automatic upgrade when both peers support it.
Yeah iOS supports BLE Coded PHY since the iPhone 12 / iOS 14. The tricky part is negotiating it at the library level. flutter_blue_plus doesn't fully expose Coded PHY yet so I'd need to handle it through platform channels on both sides. It's on my list though, the range improvement would be significant!
Oh, I thought that support was only present in some iOS 13 beta and then disappeared again? (At the OS/driver level; I’m pretty sure the hardware supports it.)
You're right, I was wrong about iOS 17 auto-negotiating Coded PHY. After digging deeper, Apple did support it briefly in iOS 13.4 betas but pulled it in iOS 14 and it hasn't returned. CoreBluetooth still doesn't expose PHY selection at all. The iPhone hardware supports it but the OS won't use it. So BLE Long Range is going to be Android-only for now. I've updated the roadmap to reflect that.
... Your examples seem to undercut your point if I'm understanding what you're trying to say.
In your first example the "cost" in the form of traffic etc. was reduced so more people "buy" in the sense that they go on the road until you reach a new "cost" equilibrium. In practice that equilibrium is quite close to the original cost so it doesn't fix the issue traffic. But if that same number of people had driven before the high way expansion traffic would have been way worse; the cost would have been too high so they previously opted not to drive.
In your second example by increasing the supply of money the money ends up costing less; it becomes worthless due to inflation.
When there's more of a thing it cost less.
To be fair, building more housing can be like highway example. If there's tons of pent up demand of people looking to move somewhere increasing supply dramatically can fail to move the needle on cost because there's many marginal buyers who all have basically the same price. If you've got a million people who want to move somewhere and are all willing to pay up to 500k for a house the price of a house won't fall under 500k until you've built at least a million more homes.
> ... Your examples seem to undercut your point if I'm understanding what you're trying to say.
That perhaps you shouldn't assume that kindergarten-level theories always correctly describe complex markets?
> In your first example the "cost" in the form of traffic etc. was reduced so more people "buy" in the sense that they go on the road until you reach a new "cost" equilibrium.
So go on, do continue this line of thinking. You built more houses.... then what?
Feel free to refer to my explanation: https://qht.co/item?id=47433743 - as usual, downvoted by people who can't face the truth.
Yeah that’s induced demand and it’s a good thing for the economy.
The rents are supposed to reduce only temporarily. But the goal is to not reduce is permanently. The goal is to increase land utility. Building houses helps with that cause.
> Yeah that’s induced demand and it’s a good thing for the economy.
No, it's not good. It leads to nothing but urban decay.
That's how you get Tokyo with a crazy price bubble, while beautiful traditional houses decay into dust just 3-4 hours away.
> The rents are supposed to reduce only temporarily.
Except that they don't even decrease. If your population is growing, so is your rent. And it doesn't matter how much you build (for large enough cities).
Again, this is simple observable truth.
> The goal is to increase land utility. Building houses helps with that cause.
Yeah. The goal is social engineering to force people into shoebox-sized apartments, to be ruled by their benevolent masters.
That's also why we're getting a global pushback against it.
> No, it's not good. It leads to nothing but urban decay.
This is subjective and loaded. I don't see any concrete point you are making.
>Except that they don't even decrease. If your population is growing, so is your rent. And it doesn't matter how much you build (for large enough cities).
They did temporarily in Austin - 19% after accounting for inflation.
Overall, making a city like NYC is preferred for any country. Even if the prices are really high, it reflects the economic activity of that city. Why would a house cost ~$800k if the person living there won't make multiples of it with their wages?
> This is subjective and loaded. I don't see any concrete point you are making.
Forced (by economy) in-migration into cities is a net negative for the country with stable or shrinking populations. It leads to objectively worse quality of life for people (less living area per person and more financial stress).
> Overall, making a city like NYC is preferred for any country.
Nope. Making a city like NYC is a recipe for disaster. Europe and the US are living through it right now. How do you think we got that kind of polarization?
When it's a zero-sum (since population is stable/declining) game, the losers are not going to take it lightly. They become an easy target for all kinds of populists.
> That's how you get Tokyo with a crazy price bubble
Are you really making an argument that rents in a place like Tokyo are not supported by real value creation? Are we supposed to all live in "beautiful, traditional" heritage houses? Those houses are often a luxury, and favored by the wealthy who can live with the resulting inconveniences. They're not a sustainable solution for the masses.
