<p>Wow. This is insane news. To think you suddenly can get by with up to 25% fewer people is truly a sign of what is to come. They probably assume much fewer will accept, but still. They probably think 10-20% will actually accept. But they're confident that they can make due with suddenly quite a bit fewer people.</p>

<p>My opinion (which is about filming in general, not the glasses) which seems to contradict others' but:<p>So if someone acts up and starts screaming it's suddenly ok to film, or even when people are committing crimes on board it's not ok? Who's to say when this is happening or not?<p>If filming is banned there will be less evidence for when this does happen, and people could get away with more crimes (although admittedly the bar is higher on a plane and the flight staff's testimony will carry lots of weight).<p>I think planes are public places (because 200 people are crammed into a tiny tube of metal) and your expectation of privacy should be diminished there. There are too many potential things that could happen on a plane. People are too close and vulnerable while on a plane. We cannot run or protect ourselves as well.<p>And as far as flight attendants, unfortunately they are at least partially responsible for both the safety and wellbeing of those on board. That is literally their job.<p>Banning filming of them will reduce their sense of urgency and responsibility, just like it would of cops if we were not allowed to film them.<p>There are just too many things that need to go right and also that could go wrong on a flight.<p>Just recently someone took a photo of an ostensible pedophile while on board conversing on a website for pedophiles and now the world knows. If all photography or filming was banned then this wouldn't have happened.</p>

<p>There's a big difference between keeping all of your ownership and giving it to the son and paying a huge salary and making him non-executive chairman while giving away most of your wealth.</p>

<p>He was chairman and CEO for a long time. Since he has only been a chairman for not that long I don't think it's fair to say that he's been a very active chairman for a long time.</p>

<p>He's there to maintain the very unique culture of the company. I think it's sort of like if they have his son there he of all people should know Buffett's/Berkshire's culture and be able to best maintain it. He's got a few years to figure out a successor. But yeah this is mostly about the unique culture they have.</p>

<p>I do wonder if the more they goose their ad business the faster it eventually falls. I know I am more and more reluctant to view many normal Web page ads at all and usually immediately click away the second a site gets annoying</p>

<p>They can be doing fine at AI models but not so well with AI revenue.<p>Although I am curious if they are not worried and playing the long game confident that their distribution will eventually help them catch up (and worst case they own some of Anthropic). But obviously Anthropic and OpenAI have their own distribution now too.</p>

<p>Anyone know how/why this one can take so many more HRV measurements? I mean the other ones can. What makes this one take more often? Guessing they are just setting it to do more. This is one thing that really annoys me is that it will go 4-6 hours without taking any measurements.  When I am sitting down working etc.<p>I tried Google”s new Fitbit for a couple days but it only does them at night!!</p>

<p>The comment in the parent said "kind alphas the agent found". It linked to a job then a trial. All of the comments I read there except for one said things like "The final alpha check is still fitting; the prior lagged backtest’s exact zero metrics make clear that model was not acceptable economically". One said "successful backtest’s" but did not expound on what that means or anything. I was looking for the alpha it found and not the feature engineering.<p>My backgroud is in finance but do not look at things so quantitatively.<p>Here is another comment/output: "correlation −0.007 and directional accuracy 0.498". Wouldn't directional accuracy have to be greater than .50 to be profitable?<p>Forgive my ignorance I am interested in this though. I have asked Claude/ChatGPT to show me where the alpha is that the model found as well so I can learn.</p>
