> Power saving is great, except when it breaks apps.

That's a problem.

> Pandora-like web app that plays music. When my app is in the background and the current song ends, it won't play the next song because iOS has suspended Javascript execution in the name of power saving.

I think that's intended. I would argue that you are misusing the web. I would argue that most users don't want websites to run while the browser isn't in the foreground. If you want to elevate your capability to interact with the user while in the background then build and install a native app or leverage existing native apps' functionalities.

> When my app is in the background and the current song ends, it won't play the next song because iOS has suspended Javascript execution in the name of power saving. The event handler never fires when my app is the in background or when the screen is off, thus, I can't play the next song.

That's good. I don't want garbage in the background to do anything javascript-related at all.

> This effectively makes it impossible to build a functioning audio app/radio station on iOS using web technologies.

Really? There are plenty of audio/radio apps on iOS using native technologies. You're trying to shoehorn something to do something it wasn't intended and then causing noise because it doesn't do what it wasn't intended.

> I've reported this issue to Apple some 2 years ago, but they still haven't fixed it.

What bug? You think this is a problem caused by power saving? No, it's not.

You've already stated that the song is playing until it ends, but that your javascript doesn't get notified that it ended. You think the problem is that power saving is stopping you from processing the next song to play. I disagree. I think the problem is that you aren't providing a play list to the browser. Frankly, I'm not a web developer so I don't even know if there is a playlist API. But if there isn't, then that is your problem.

A playlist would be a hell of a lot cheaper than trying to run arbitrary javascript.
Since this is an article about an Android phone, I realise giving an iOS solution for this may not be that helpful. For anyone using iOS, the Apple Shortcuts app has an action "Get Contents of URL". You can use this to make a shortcut to save the contents of any URL similar to using wget. I often find this useful, and highly recommend the Shortcuts app in general. It's not perfect, but helps add missing functionality.

Been a while since I used Android regularly, but there will be a similar (easier) method for a shortcut to download the contents of a URL.

If your point is that applied morality is complex, I don't think you're saying anything new.

But you replied to my point about abusers exploiting the well-meaning and naive. I don't see what bringing up an obvious fact about moral complexity does here, especially since you refuse to engage usefully with your own point. Except of course to confuse the issue.

In practice, I don't think I've seen any attempts by Epstein associates to really grapple with the moral balance, to weigh the ends against the means. What I mostly see is them taking the money and either supporting him or dodging the hard questions. There isn't anybody willing to say, "Yeah, I suspected he was a manipulative, sex-trafficking pedophile, but I was cool with it because here's what the world got out of it."

There are plenty of good places to discuss moral nuances. But maybe try it in a place where it doesn't derail from holding people accountable for their behavior.

If it was the best, the entire US commercial generator fleet wouldn't be on death's door due to the economics.

If you want to subsidize the last 59 US nuclear plants based on their low CO2 emissions, extending their operating license (if it can be done safely) until cleaner base load arrives, that's a sound decision. Building more nuclear is not. I question if we even have the fortitude to fund safe cleanup of existing decommissioned plants (spent rod casks have been sitting onsite in Zion, IL 19 years after that nuclear generator has been shut down, with nowhere to go [1]).

Batteries will get cheaper faster than nuclear ever will, considering every automaker is moving to electric vehicles [2].

Really anything that you're remotely curious about outside of what you do at work. Engage with something with genuine curiosity and you'll almost certainly find it leads you to a hobby you can try out for a few weeks. Get deeper into it or move on to the next.

Just to get started: instruments/music, foreign languages, cultural events, theatre/art/design, local volunteering, civic engagement/politics, outdoor activities, cycling/sports/yoga/gym, pets, travel, investing and finance, continued education (moocs/math/history/etc), meditation, ham radio, tabletop/video/retro gaming, books/writing/blogging, gardening, woodworking, cooking. Even "programming" things totally outside your field (little overlap with your day-job) can make for a good hobby if that's your thing.

Some are more fun than others to talk about to other people but that's not the point. I find whenever I'm feeling burnt out or stressed my problem is usually that I'm focused too much on work and not getting satisfaction from the rest of life. Hobbies can make up the rest of life.

Do you have a source for this? The article you linked to quotes one 2014 HBR article and then walks it back, saying, "all studies in this area have found that the majority of successful start-ups have founders under age 50".

And there was also this more recent HBR article "The Average Age of a Successful Startup Founder Is 45":

There is a recent US Military study that shows that under a severe caloric deficit and with increased energy expenditure that yes, you still preserve lean body mass. [0] Granted this was not fasting, but it's interesting nonetheless.

Don't be thrown off by the title. Yes, one group received testosterone, but even the placebo group that did not receive anabolic steroids, lost nearly 10 pounds of fat without losing any appreciable amount of lean body mass.

Dr. Peter Attia wrote about it in his newsletter this past week. [1]

Between my anecdotal experience of not feeling like I lose much lean body mass while fasting, this study above, and recent evidence from studies shown that "muscle memory", where a muscle can quickly regain any lost size it has had, is in fact real...I don't lose much sleep over losing muscle while fasting.

> I said that NOT ALL ads are bad

Ads are inherently trying to make me want something I don't want, so I'd say that all ads are bad.

> most people need funds for their work and selling stuff or services sometimes isn't an option.

Why is that, exactly?

Nobody has to sell ads. If you business only works because you sell ads, your business model doesn't (or shouldn't) work. I don't think that we as a society benefit from propping up businesses who produce content that is so low-quality that nobody would pay money for it.

> So if you're talking about tracking ads, I'm totally with you.

What ads aren't tracking me? There are only a few ad networks who even claim not to track you, and it's unclear how many ads those companies actually serve up--it's certainly not a large portion of the ads on the internet. And as far as I know none of the ad companies out there have open-sourced their code, so whether they're telling the truth is a big open question. Advertisers certainly have lied about this in the past. Apple, for example, has been dinged for this a few times, while trying to sell itself as a privacy advocating company.

WITH evidence, click through and conversion rates are very low already, so it's pretty hard to persuade advertisers to advertise without collecting as much data about you as possible. So nearly all the ads out there are tracking ads. Even if you only accept that all tracking ads are bad, the word "tracking" is only a minor technicality.
here are the hobbies I have had

archery, bowling, pool, mountain biking, ice hockey, inline hockey, floorball, ultimate frisbee, sailing, windsurfing, kitesurfing, rock climbing, shooting, reloading, hunting, home improvement (has a lot of sub areas), games programming, tae kwon do, kung fu, krav maga, jiu jitsu, paint ball, role playing games, online games, being helpful on forums, scuba diving, piano, golf, camping, chinese, poker, chess, settlers of cataan, cooking.

These are all activities that I have done for at least 6 months on a regular basis.

There are many things Ive only done a few times but will definitely do in the future (surfing, snowboarding, drone flying, 3d printing,etc)

At this moment I mainly mountain bike, kitesurf, krav maga, and bjj. In the winter I will snowboard and on my next beach vacation I will hopefully surf.

I am surprised when people keep saying here that RSS is dead. I am using it more than ever, every site (including hn news) configured by topic in Inoreader. I even have reddit feeds within it via inline reddit. This way I can see my read/unread counts and mark favorites. I can also quickly export my feeds. It works cross device and it's the only source I use for news, articles or anything else I read on web. If site doesn't have RSS that's shame and I probably never visit it again.
I'm using RSS feeds daily (even for HN), so it was a no-brainer to add RSS support to my blog as well. I've also created Tip of the Day [1] - while the daily tips can be accessed via an HTML site, I have written it mainly with RSS in mind.

I'm not in my early thirties and time anxiety is actually growing stronger. I worry about the big three: children, career, and personal health. My idea is that with kids... my finace and I are aging. Are we going to do this or not? We have to know within the next 2ish years. With career... what career path do I want to take? I need to focus on schooling or professional certificates ASAP so I can utilize those as I age. With health... how many years of testosterone do I have left? I'm very skinny and would like to build a basic muscle structure, not for vanity but for general health.

Why not discuss the article rather than post drive by links to supposed "bias fact check" sites which don't themselves seem to be authoritative....?
Behaviorally, it's a dead practice.

As individuals, we used to look at all content ingested by readers (programs or Google Reader/feedly) and ourselves cherry-pick the articles, posts we wanted to see. Like an old newsgroup reader. Gradually that function has moved into programming beyond your control showing you suggested content filtered via models that show you only what they think you want to see. Buzzword: AI. Roll your eyes.

Some sites would provide a teaser, others full content, some would put an advertiser's message in the body and a catchy title. It was up to the content maker. Typically there'd always be some reduction in the actual markup/content itself. Interesting things you really liked you might have clicked into and seen on the original site for a full experience, fed those people's ads and analytics. But the bottom line is it all largely interworked.

One of my favorite things was using iGoogle or netvibes because those two flagships took RSS widgets. Using either custom programming or something like Yahoo Pipes you could cobble together something useful. Like make your own google homepage or dashboard containing both your calendar appointments, filtered gmail, and quirky things like server uptimes, alerts, API usage limits widgets, fun webcomics.

From a publisher's perspective, RSS is still used to connect disparate publishing systems together since it's a standard. From one content management system you can pipe material to a blog widget, to a mobile app endpoint, to a partner site, to an affiliate. Direct site hosting is down but even now we use RSS to feed media partners like Facebook instant, Google News producer, Google News on [Voice] Assistant, twitter (via publish vendor), Apple podcasts (actually that might be JSON, but maybe wasn't always?), etc.

1) what was never clear to me was if the resistivity of an infinitesimal volume element of superconductor is strictly a function of temperature, and the norm of the magnetic field, or also of the direction of current with respect to the direction of the magnetic field? near the critical current density, or even before, will the resistance depend on the direction of current?

2) while a general bulk high current superconductor is limited in currentcarrying capacity this way, most of the time one is not interested in sending current one way, but also completing the circuit and getting current back the opposite way. Why can they not make power distribution cables with indefinite currentcarrying capacity the following way: consider a "multilayer" coaxial cable where the conductors are superconductors, and to prevent a magnetic field from arising the layers have alternating current directions, so that in any layer the net magnetic field is below the critical magnetic flux? (this would only be for power distribution, since this can't be used to build stronger superconductive electromagnets). The total current would be the sum of all the even, or of all the odd coaxial layers (the 2 sums are identical since they complete a circuit...) in essence co-locate the 2 problematic magnetic fields such that they cancel...

Well yes, at our current technology levels ecological and climate based collapse has almost no chance of making humans 100% extinct. But I don't think that anyone is arguing the opposite.

The moral calculus for addressing climate change isn't that affected by differences in the survival rate of 0% vs 5% vs 50%. All of the above would be catastrophically bad in human terms.

If you can build and fill luxury apartments I don't know why you would build apartments for the poor: the profits are higher in the luxury apartments. California has a big problem in that they make it too hard to get the permits to build anything so everything that goes in is luxury apartments (they force low income housing, but this is forced)

However what if we changed things: you could easily get the permits you need to build whatever. After a few years the market for luxury apartments will be saturated. Now when you look at the do I build lower cost apartments, or luxury apartments you build the lower cost wins because your expected income from luxury apartments is zero.

Actually the above isn't true in good cities either: all new apartments are luxury. 10 years latter they are out of style, but it is cheaper to rent them for less than to remodel to whatever the latest style is. After 50 years they are low income housing because only low income people will accept the dated of a style. LA hasn't been building enough for long enough that this can't come into play.
those aren't the only two possible outcomes. I went to a pretty good state school with pretty generous admissions criteria, but very rigorous coursework. most of the required courses for stem majors started at the 200 level. if you got a "good" highschool education (ie passed calculus) you were expected to start with CS-201. if not, there were lots of gentle 100-level courses to ease you into programming or teach high school math material that you either didn't take or failed. note when I say gentle, I mean the material itself is not difficult. you would be assigned a large quantity of work in every class at every level.

plenty of kids failed out along the way, but it was more because they didn't put in enough time than being hopelessly underprepared for the rigor.

you do kinda have to give up on the "undergrad takes exactly four years" thing if you want this to work though. some people will need to do more than 120 credits to fulfill the requirements of the degree. not everyone will be able to take a full-time course load every semester or even any semester. that doesn't make the end result worse when they finally graduate (though it may be more expensive).
