<p>Back when Phoenix launched it was not a reliable alternative to IE or Opera, it was more like a sign of protest. You’d use it to tell the world that you didn’t care if most of the internet didn’t work for you, as longs as you where “sticking it to the man”.<p>I remember developing web pages with the purpose of ensuring they would work in both, so Phoenix was my main driver, but whenever anything was “done” the real work started of also getting it to work in IE, it was always a monumental effort. Sites with buttons for “go here for pheonix/go here for ie” where common. My friends who worked in the windows ecosystem mostly saw Phoenix as some “crazy hipster trend” and didn’t have a care as to if anything they made worked in it or not.</p>

<p>>  then why even have source control?<p>I know you are joking, but the answer is the same. Because the agents need it, not because any human need it. The Agents quite actively use the history. It's more effective than any comments or separate documentation might be for the agents working on the code.</p>

<p>Developers using rails are of cause not too satisfied with an answer to their question of “how will rails make my life better in the future?” Being “it won’t, use an AI coding agent and let it write rust for you” but it’s a keynote not a marketing pitch. If would have been silly to do a talk about some minor changes to rails and then open the conference where everyone except artisanal code carvers would talk about exactly how they’ve replaced most of that they used to do by hand carving with AI automation. He’s not talking about some far fetched future he’s talking about that has happened the last year.</p>

<p>Absolutely crazy concept. But looks like they actually threw something decent together. I'd wager the bulk of problems people face with teeth come from poor flossing, this makes it effortless to avoid that.<p>I've owned water jets, the ones I've had suck. I always end up going back to dental floss. These days string on a plastic holder which I hate because it feels so wasteful to have all that single use plastic, but they are just so effective and I hate the manual wrapping of string, so I accept the wastefulness reluctantly.<p>This product potentially hits home with what I'd want from an effective waterjet, and it also comes with a brush on top.<p>The price is high, that's for sure, but I'm guessing they aren't aiming at the average electric tooth brush market, more like a competitor to the oral b io series 9 segment. And sure they are quite a bit above that price point, but they got a lot more of a solution backing the price.</p>

<p>The Traditional View (How it actually works):
If an investment fund manages $1000 of your money and charges a $150 management fee while keeping your $1000 completely separate, they made $50 on $150 of sales and have a 33.3% profit margin.<p>The "Insurance Style" View (If they copied UHG's model):
If an investment fund counts your $1000 deposit as their own revenue and treats buying stocks for you as their own cost, they made $50 on $1150 of sales and have a 4.3% profit margin.<p>The distinction is that the insurance company is not selling you medical services; those are covered by your and other clients' own money. They are selling the service of managing a central fund to reduce risk for the people who are part of it. For them to claim that you were paying them for medical services, they shouldn't just be covering the hospital bills—they should be operating the hospital and buying and selling the drugs themselves. It might feel like they do that, but this is actually done by the healthcare providers and pharmacies, with the costs merely covered by the insurance fund.<p>Grocery-Bagging Analogy:
Imagine you pay a teenager $10 an hour to help bag customers' groceries. In that hour, $2000 worth of groceries get bagged, and your business takes a $100 fee from the store for the service. After paying the teenager, you pocket $90.Do you claim a 90% profit margin on your $100 service fee? Or do you claim that your "costs" were $2010 because you included the value of the customers' groceries, pretending your margin was a measly 4.3% while walking away with almost all the fee?</p>

<p>> If the research can't demonstrate the DK effect, then the research is bad, like poorly designed.<p>It’s the opposite problem. The research is bad because it “demonstrates the DK effect” even for cases where it cannot possibly be true. Like “people who tend to roll lower dice rolls overestimate their own ability to roll high dice values and people who tend to roll higher values tend to underestimate their own ability”<p>Which is just obviously incorrect and the true result should have been “there’s no correlation between people’s estimate of their ability to roll dice and their actual outcomes”<p>If you want to demonstrate an actual effect like DK, you have to set up an experiment such the if it truly doesn’t exist then the experiment tells you so. A great way of checking this is to throw random data at it in which case it should come out saying “I saw no correlation” but that’s no the case with their setup.</p>

<p>>  I could not reliably assign authorship percentages to many of my own recent projects.<p>This feels like a strange statement. Unless you are going out of you way to disguise AI contributions it's extremely simple to do some git magic to get an exact percentage. But you can also just ask AI and it'll tell you directly. And even if you've tried to disguise it I'm fairly certain that if you set aside 10$ for tokens, it'll be able to deduce how much is AI even with someone having tried to disguise it.</p>

<p>That’s a misconception. Glass does not flow over time; it is a rigid, amorphous solid.
The uneven thickness seen in old cathedral windows is a result of historical manufacturing. Glass was spun into discs that naturally became thicker at the edges, and builders installed the heavier side at the bottom for stability. Physicists calculate that it would take longer than the age of the universe for room-temperature window glass to visibly deform under gravity.

<p>The noice isn’t about the effect, it’s about trying to scale the outcome. We essentially have proof of a method that is significantly better than what is used with the broad population, but we cannot scale it to the broad population. That’s the “problem” in the two sigma problem.<p>And in general ongoing from “it’s obvious to me” to a quantized effect is always an effort. For instance I don’t believe you are correct in assuming that one would see a two sigma effect in physical exercise when comparing someone who attends a regular exercise course va someone who spends the same time with a personal trainer. Two sigma is a lot, and you won’t be lifting significantly heavier weights from hav a PT vs doing starting strength training. In my opinion you would most definitely see a two sigma effect from doing steroids though. But this is all pure speculation which underlines that part of the “noice” is about the documented aspect of the two sigma problem, where we have a body of data to work against not just personal assumptions. That said if anyone has studies on personal trainers va course work in fitness I’d love to see my world image challenged by data.</p>

<p>A lot of pessimism in the comments, but I am just happy that we are seeing some work towards bridging the 2 Sigma gap for regular education vs. elite private tutoring. I can't imagine that people assume it's the physical presence of the tutor that is making the difference, it has to come down to the personalisation and expertise which is exactly what AI can provide in a form. And yea it might not be "there" yet. But if we don't start trying and studying then it'll never get there.</p>

<p>> Oh so she cares about her own privacy?<p>She didn’t choose to make that move. PET (the equivalent of FBI) made the decision to protect her address. I’m sure she much prefer the time back when she was living at her own place and her address was freely available to the public without any issues.<p>There is no hypocrisy here.
As for releasing social security numbers of people, she’s against it no matter who’s doing the doxing and who the target is. But yes, obviously the government knows hos government issued ID corresponds to who. That’s pretty obvious. But that doesn’t mean everyone in the country has to have access to it. Your doctor also has access to your medical journal, that doesn’t give you the right to publish the medical journal of your doctor on Facebook if you get angry at him for giving you a bad diagnosis.</p>

<p>By what metric? The fact that he got arrested for stalking the prime ministers children and releasing private information speaks toward protecting privacy not an issue if lacking privacy.<p>You can’t just declare “I am an anti violence activist” then go out and beat up politicians and declare that the system has a problem with violence when you get arrested.<p>This is the equivalent of what he’s done. He claims to support privacy laws so he violated the privacy of someone who is currently protected by the PET (equivalent of FBI) due to safety concerns and he proudly proclaimed that he did so by stalking her children. He’s not a political activist he’s a drug dealer who’s hell bent on getting revenge on politicians because he just spent 8 months in jail after being convicted on counts of death threats harassment and illegal possession of arms and drugs.</p>
