> Yes :- ) Do you mean 1) for yourself only, or 2) for all site visitors (so those replies would be collapsed by default, for everyone) ?

Rather for myself, but as an account setting so that I don't have to collapse them manually for each thread. Actually it stems from something that bothers me with HN: when there are a lot of nested replies, I lose track of the which comment corresponds to which parent. For example, try reading this thread : https://news.ycombinator.com/item?id=22705222, I find it difficult.

If there are 5 comments (level 0), that each has 10 replies (level 1) and each one of them has 10 replies (level 2), I wish I was able to collapse level n>0 replies to read the comments first, then be able to unfold level 1 replies for the first comment, while keeping level 2 hidden, and so on.
This might not be the ideal solution, maybe simply the way you added arrows to replies would make the above thread easier to read.

> What things lag the most? (Some specific button(s) or animation or scrolling or ... ?)

I just found it's not specific to android (I'm using Android 10 on a recent galaxy smartphone). Mostly animations. On the desktop version, If I click on the plus button near 'Chat Channels', the login window is show progressively, and the background is dimmed in way that 'feels' slow. Also when I unfold a collapsed reply, the page moves slowly (is there a reason it moves ?).
When I click reply, a window is shown, 'loading draft...' appears then disappears quickly and then the preview is highlighted, it somehow feels slow.
Useful to know is the exception is printed to stderr, not stdout. So if you continue the pipe after head you still get expected results.

cat doesn't die 100% silently either, check $PIPESTATUS after piping cat into shorter head and you will see its exit code is non zero.
If I am not mistaken, gas chromatography gives you composition, not proportions. That’s not a minor hurdle in this discussion.
sorry for going on a tangent ...

is there such a thing as populism in physics?

I have read couple of Brian Greene, and Stephen Hawking's books (also read some to my kids "the key to the universe" which he wrote as children book together with his daughter iirc) and I/we loved them. It made me wonder if the gift of writing good prose (and in Hawking's case his disability and popularization of mechanic speech especially) has contributed more to his success than his actual scientific research.

Somewhere I read that people in his field weren't happy with his contribution. They didn't say it as bluntly as myself but it sure sounded a lot like it.

Is there such a thing as populism in physics - and if yes is it more pronounced than in other fields?
“ Pharmaceutical company Roche announced Friday afternoon that it will release the recipe for its lysis buffer if Dutch laboratories ask for it. ”

Is what the article says. What it doesn’t say is whether Roche will actually do so, or use stalling tactics. One shouldn’t count their chickens before they hatch.

I have also read that it takes between 7 and 14 days from infection until you start to show symptoms. From your comment that would mean that anyone showing symptoms is "probably not that contagious". Given the exclusion rules rules here in the UK that doesn't sound right. What piece is missing?
Ask HN: Recommended materials for technical-leads in machine learning?
I just became the technical lead of my companies artificial intelligence team and I would like to do my job way better then I do it right now. What kind of books and other materials can you recommend for this?

I emphasized "machine learning" as I need to manage both engineers and researchers, and connect the tasks to the business needs. But there is a higher uncertainty in the output of the tasks than in "classical" software development.

Maybe I am wrong and there is no targeted material for this, but I am sure this community can advise me some great stuff.
No, definitely not: ‘boids’ serve to show how synchronised collective behaviour can arise in swarms of agents that can observe only a handful of their closest neighbours whilst following pre-determined rules. Virii have no such perceptive capability.

S-I-R (Susceptible, Infected, Recovered/Removed) models of epidemiology are a far better place to begin for reasonably realistic and tractable modelling and prediction of epidemics.

This is absolutely correct - we need all front line people-facing workers to be tested on a daily basis.
This is a difficult call to make. Of course, the government shouldn't be the automatic fall-back solution for incompetent/greedy management. On the other side, large companies failing do have a network effect, that is why the government does bailouts in the first place. There are arguments that the 2008 crisis could have been avoided, if the government had bailed out Lehman. Lehman failing caused the crisis and in the end many more companies needed and got a bail out and still a huge economic damage was done.

The only solution in my eyes for this dilemma is, that the government should do bail outs, but at the price of shares. For any money paid, which isn't just credits, the government should get company shares, which are sold off, as soon as the market stabilizes.

Ask HN: What software do use to create and/or manage your schedule?
I recommend one of my favourite books, Gary William Flake’s 1998 The Computational Beauty of Nature to anybody interested in boids or other computational models of social, chemical, and physical phenomena.

Therein the author covers boids extensively and in detail. If I am not mistaken it is in section 16.3 that the author treats boids fairly extensively.
Achieve Your Goals

PWAs could answer this problem, at least to some extent, but Apple historically has been limiting the features to protect the AppStore and the Apple Tax (v. the recent local persistence changes in ITP).

It's better than, say, Google pretending that third-party cookies make the web a safer place (yup, that happened).

(Don't get me wrong, I think ITP and Safari are great)

> Get mad at Apple for not letting you wireshark your own iPhone.

People on HN can, but an average user shouldn't have to care about that. I'm 100% up for stronger legislative measures (both tech and dark UX patterns) and more education in this area. Sounds boring, but without it we'll just keep running in circles.

I have an implementation here [0] if people want to play with it. Supports dynamically changing the controls, has obstacles and predators. Setting weights for separation, alignment and cohesion to zero and then increasing only one of them nicely shows which role each of them plays. It's actually made as a workshop [1] for my company, where the shell is provided and one has to implement it step by step. In Norwegian, though.

Update: Dang linked other discussions, and I see I commented on one from 2015 [2]. Someone there asked for the course content, and that's available (in English!) in a PDF in [1]. This workshop/implementation is actually an example of what I wanted the students to make at the time. Which I then retrofitted to a fun workshop for my colleagues.

A well-crafted, organic, gluten-free macOS app is generally the best UI and UX experience on any platform, by a mile. Apps that come to mind are Things by Cultured Code and (the as of yet unreleased to the public) Nova editor by Panic.

No Electron app has ever even come close for me, certainly not VSCode that everyone seems to love so much.

Then there's performance...
Test are extremely important. Here in Spain, a PCR takes more or less 24h.

With fast testing you can control a pandemic BEFORE it gets out of control, like South Koread did. You control every single passenger an the border, at airports, so it does not spread to general population.

If there is someone who is not detected, when you do you control the people in their environment.

Making millions of people stay at home is a FAILURE of the system. You should control hundreds or thousands, not millions.
legally, how are they able to do this with books that aren't public domain?
> I don't get what introvert has to do with focus.

I interpreted 'introvert' as a verb, even though the domain name suggests otherwise. As a verb it means to turn inward or to direct something (attention) within the self.

We really should make a introduction video.

In the meantime Julias blog post (https://jvns.ca/blog/2020/01/05/paperwm/) have a short gif demonstrating scrolling and this PR (https://github.com/paperwm/PaperWM/pull/225#issuecomment-575...) show the newish drag'n'drop functionality.
And frankly, on macOS, VSCode isn't even THAT great. The UI certainly doesn't follow platform conventions, the scrolling is janky, and it just feels out of place.

Additionally, I have yet to encounter a single native Cocoa app that has such a strong effect on battery life.
Apple has definitely been shitting the bed on UI in the past few macOS releases.
Leica invented 35mm(135) format compact camera, and soon after added a rangefinder framing/focusing system. Nikon cloned it, then replaced the viewfinder with Single Lens Reflex system, a system that uses a mirror behind the lens and a prism in shape of pentagram, forward of viewfinder, to directly view through the lens to frame/focus.

Those were introduced in 1930s and 1950s respectively. Since the launch of Nikon F in 1959 until some time in 2010s the viewfinder technology didn't change. Means shutter became metal and electronic, autofocus invented, man went to the Moon and back, digital CCD/CMOS photography came around, Sun goes down but mirror and prism SLR technology of 1950s just kept on.

One of the reasons why mirrorless didn't appear sooner is because LCDs or OLEDs viewfinder suck(ed). They used to be in SVGA or XGA resolutions, refresh at 30-60Hz or less, few hundreds ms late, dim, power hungry and whatnot. Wasn't so advantageous in terms of weight or cost as well. Optical quality of SLR viewfinder never disappointed its users on the other hand. It is and always had been a joy to be able to just look into it and see through the lens, especially when films take hours to develop.

Sony, however, knew that no one uses viewfinder in a point and shoot digital cameras, or no one has any problems without SLR viewfinder in video cameras, dad on holidays and professional broadcasters alike. So after they merged camera division from Konica Minolta in 2006, they just walked out and spoke out the obvious. Camera nerds were shocked, I was shocked, so were Nikon and Canon. Leica may have been laughing, Zeiss was happy collecting licensing fees. I was skeptical, and I could verify it feels very disappointing looking into EVF. But Sony knew it ain't a problem and it wasn't.

Nikon and Canon probably thought the quality of EVF never satisfies professional photographers, from their narrow expertise.

How much?? Can most students even hope to make this amount back once their degree is over? That’s 120k of tuition after 4 years. To sa nothing of the interests on that debt or the opportunity cost. What are the employment prospects for art graduates?

Closet racism. There is far more evidence that Europeans destroyed these cultures and ignored their advances, than there is proving this so-called myth.

We are STILL uncovering major advances in these cultures today.

As a new Fuji x-t30 owner myself, the camera controls just make sense (unlike PASM) and the shooting experience is so much fun.
It'll most likely be abandoned in droves. One of the main reasons to stick with C++ (and C) is that the investment you put in the code you're writing right now, no matter how fugly it is, will be there and keep working in the future.

Also:

> I think it also makes sense for C++ developers whose projects are relatively short-lived, e.g. some games.

There is a difference between games and engines - the games might be short lived, but most C++ engines are very long lived, going back decades (e.g. see how the recent Half-Life Alyx can trace its codebase back to Quake 1 or pretty much anything based on the Unreal Engine going back to the mid-90s - there are screenshots of UE1 running on what appears to be either Windows 3.1 or NT 3.51). Even when "engines" are being made "from scratch" this is often a marketing gimmick and the "from scratch" was just renaming the engine because it got a new rendering model and people can't tell the difference. EVEN when this isn't case, often new engines are based on existing code and/or libraries.
I think the closest anyone can get to the glory days of Amiga hacking today, is to be found in the ZX Spectrum Next - which looks to be becoming the most profound hacking platform for lovers of alternative computing environments, so far ..

https://www.specnext.com

The things people are doing with this amazing machine today really remind me of the life and enthusiasm that was in the Amiga scene back in the day.

Perhaps with the success of the ZX Spectrum Next, we might see a new wave of machines, which build upon their 80's ancestral architecture and provide a way out of the walled gardens in which we are all trapped ...
Won't that either need a lens the size of the rx100's (way too big for a phone) or just be poor quality?
because environments everywhere have adapted to a rhythm of temperature that will no longer exist due to global warming. a good definition of damage is "harmful change."
Actually both of the first arguments have a lot of merit, but can be phrased in a more professional way: "It's a well proven technology and many members on team already have experience with it so few deployment surprises expected and no training required."

And what's more important, even if you write something embarrassing like "i don't know of any other tool, but this tool seems to be good enough" in the journal, that is very useful information to know in the future, vs "we did thorough evaluation of 4 different libraries and found out the others does not support important use case X".

Being a heavy, long-time RSS user and having tested both the macOS and iOS app of NNW, I think you’re wrong. NNW it’s incredibly well-done, fast and polished, and it’s the best RSS app I’ve ever used, and I’ve used plenty. It’s not unrealistic to think it will become successful and relevant, maybe even contribute to a resurgence of RSS and bring in new users, given enough time.

I recognize the phenomenon. I once had a roommate who changed his major to communications and then bragged that it was his life's calling and he was the best at communication. He fought with us over stupid stuff and never learned to listen. Drove us totally insane. He used to say that we were going to be bad husbands in the future because we didn't mention things that bothered us as aggressively as he did. Another friend who studied communications very seriously said that many communications professors had marital issues because of their belief in their own abilities. Totally anecdotal, of course.
There would then be two C++ languages. The overwhelming majority of users would stick with the old one, a scant few would take up the new one, and the rest would move on to some other language.

This is unsustainable. It requires constant vigilance and turns the privacy matter into a cat and mouse game where we are constantly one step behind the worst actors. These systems exist everywhere in the world and they’re fundamentally inefficient. E.g. recycling, or “please bring your own plastic bag”, which relies on goodwill.

Compare to a system where you fix the incentives to automatically align everyone’s interests: e.g. bottle deposits, or a small fee for plastic bags. Now people will want to do the right thing, because it is aligned with their own interests.

The same holds here: fix this one instance with enough outrage, there will be a thousand more. Instead, let’s fix the misaligned incentives between app builders and users, so their invasion of my privacy costs them as much as it does me (e.g. GDPR).

This is how you make efficient markets: align incentives. Fixing everything on a case by case basis only provides temporary relief.

[edit: note that OP never said "don't do it", they just said "it's missing the point". which I think is a fair call. this one fix is good, but it's unsustainable.]
