These kinds of comments block me from doing a physics dive; I don’t know where to start/am worried about starting from a bad point. I don’t know whether to follow some of the trails the linked author has laid out if I want to learn more, whether you’re nitpicking, or whether you’re advocating for a much better approach that starts with the details you say this obfuscates. When I was younger and had more time I’d be willing to eat the inefficiency, and the bigger reason for not doing a deep dive is the difficulty, my own laziness, and lack of practical need, so take what I’m saying with a grain of salt, but the time needed to parse criticism like this to see whats legitimate and whats not drives me a bit nuts.

I’ve done enough self learning to know that there is no perfect starting point/backtracking is inevitable, but something about the modern intellectual landscape feels very noisy/jargony and particularly prone to inefficient learning.

When you say “there is translation invariance that using the Noether's theorem implies the conservation of momentum”, I have no idea what that means. It sounds like a description of a turbo encabulator. I’m sure its not, and that your description is much more efficient than spelling it out from the ground level, but it annoys me how difficult it is to distinguish between a legitimate domain expert jargon meant to condense complexity and unnecessarily obfuscatory jargon that works more like a status/club membership symbol.

Maybe its always been like this somewhat and that problem is inevitable, idk.

I don't have any articles to back this shower though up, but I assume people fear becoming the English post pax-romana. Being in a world where you can't even conceive to rebuild something your ancestors built is a bit disturbing. If you're not progressing, you're backsliding.
The West has already made its choice. We have chosen to do nothing about declining birth rates among the native population and have instead chosen to supplement the population with immigration from developing nations, or whatever term you wish to use for those countries where birth rates are still high. The numbers are plain to see. Where once an extended family was the norm (it takes a village…) now families are atomised. 2 parent or increasingly 1 parent families. Even when an extended family exists (grandparents are still alive, everyone is still married and on friendly terms) it is common for people to move to where the work is. This may be many minutes or hours away from the new offspring.
My gut feeling is that there's a strong correlation between rent prices and fertility rates. You can't have kids if you can't work out where to put them.

That said, I'm generally quite relaxed about the population trend: the 18th and 19th century had ballooning populations in Europe, and collapsing populations everywhere else. I don't think it's going to get to the point where there are serious overpopulation problems in the global south - at least, nowhere near what we already have in Europe.
Right, but how is this fact in any way helpful in dealing with the phenomenal world?
We’ve borrowed trillions of dollars from future generations, and have guaranteed ourselves trillions more in retirement benefits.

If the population goes down, each individual is going to have a massive burden of debt and taxation to shoulder. And you can imagine a scenario where this creates a feedback loop of dramatic economic decline.
It’s interesting that you say this because, and this doesn’t change my opinion about its value, education is strongly correlated with a decrease in birth rates in developing and developed countries. There’s also a strong correlation between high marks at a young age and high degrees of success later in life, regardless of grades or performance in between. Taken together, Macron’s policy could actuallly harm the birth rate.

I completely agree that families should get more support. I’m just not so sure it’s necessarily that straightforward.
I don't see how they can keep that promise. Who foots the bill after the company stops existing? The founder? What if he gets hit by a bus?
-People spend more time thinking about what they might lose instead of what they might gain by doing something. Partially, this is because wealth and prosperity are generally higher.

-People were more likely to ignore things they didn't like, and so building consensus was faster when dissenting people simply weren't talking. It's more common now to encounter people who feel it's their civic duty to search for things they feel are undesirable.

I think this is a fantastic recommendation! Having come to coding from the same background (++Python), I feel the need to tighten up my understanding a bit.
Certainly corporations drive some of it. But I do think there's also a cultural element. I've lived all across the US and the places that lack those amenities simply don't want them from my experience. Even when they do get implemented by well-wishing civil servants, they are often openly mocked as a waste of money.
> they must shudder at the thought that in the average week the country loses another 2,000 through population decline

Anecdotally, it seems a surprising number of these young men are already fathers (of children they could barely support). Furthermore, there is a male surplus built into birth rates, and the number of men is not the limiting factor in population growth.

It's quite obvious the reason is economic. Establishing healthy families is really difficult.

> that there is almost no civil war in countries where 55 per cent or more of the population is aged over thirty.’

Honestly, the biggest advantage OpenBSD has always had for me was its internal consistency and excellent documentation. If you’re a heavy command line user, you can usually figure out either what command you need to run or what you need to look up in the man pages. It’s also great for C development, as it has far better docs for libc than glibc does.

If you have supported hardware (and that’s a bit if and caveat; smaller than it used to be, but still quite large), then everything just works. Even little things like the built-in screen brightness buttons, just work regardless of if you’re in x11 or a terminal (same with volume buttons), because it’s designed as a complete system rather than a distribution of otherwise unrelated open source projects.

Who is going to pay your pension and wipe your incontinent butt? Population decline may be fine but we need new economic and social models to support an older population.
Kids are frighteningly expensive. If I had none, I’d live in a bigger house, have more free time and would be much more free to move to pursue better opportunities than I am now. In many places your first consideration when looking for a house is which school your kids are going to.
Kim Jong Un is a funny case. There's a reason we call North Korea the "hermit kingdom."

Putin was a child during the missile crisis, but he cut his teeth in the KGB of the 70s and 80s. His mentors and leaders were, in all likelihood, veterans of the Great Patriotic War.

You can also scan a document from your iPhone and insert the image anywhere from the context (right click) menu. All it’s really doing is removing a few steps from the need to unlock your phone, open the notes app, select the scan document option and share/airdrop the result. It’s simple and effective.

I’ve seen so many students upload images for online exams via things like cam scanner unaware that they don’t need third party solutions. They complain about the time needed to get the images off their phones and onto their laptops for exams because of these supposedly hidden features.

(On Windows you can browse your android’s phone’s photos via the photos app via USB)

Similarly they go to extremes with various oddball apps to make PDFs with cam scanner images in all sorts of orientations with nasty watermarks because they’re unaware of the power of Preview.
The age might very well be correlation, not causation.

Wealthy 50-years-olds having their firstborns, then promptly leaving them vast inheritance — boom! you get “successful” children merely because they got quite a boost. Meanwhile, you don't see not-so-wealthy 50-years-olds having new kids because they had them already at 25 and that was enough.

Also, there is a whole host of implications from having kids earlier. Like, you being just 30 when they go to school — or young adults having 65-year-old parents to care of when they'd be rather establishing their own life.
Honestly, just watch videos of people playing the game. If you find someone who doesn’t annoy you, this can be a great experience.
It's because we have no national purpose because we are no longer a nation. Instead we are an empire controlled by a conglomeration of vested interests ( foreign and domestic ). We used to be able to build massive projects like cross country railroads in the 1800s. Of course it came with genocide of native americans, theft of their land and the wiping out of bison/animals across the continential US, but at least we had a direction. We are now captainless ship and instead of trying to take control of the ship and give it direction, the elites (foreign and domestic ) are simplying offloading as much cargo as they can before the ship sinks. How else do you explain legalized gambling, drugs, culture wars, fixation on lgbt, etc? Yahoo sports has the "Sportsbook" tab in between NCAAB and NCAAF.

There is no game with multiple difficulty options where hard mode is as well designed as in fromsoft games. It is therefore reasonable to conclude that adding easy modes significantly detracts from the experience of hard mode options. You can argue all you want about how in theory it shouldn't affect hard mode experience, but that goes against everything we see happening in practice.

So for the people who likes hardmode, you are extremely greedy when you want to remove the only game offering the hardmode those people want, you can just go and play any of all the other easy mode games while they have no other options. You are a part of the majority who is catered to in almost every game going to the minority asking them why they don't cater to you as well, of course they get angry.
The articles hint at some strong factors for causation.

> Imagine you were forced to do a SL1 run on your first play

I don't think that's quite a good comparison -- because leveling up is literally a method to overcome the difficulty. Grind. Get Good. Kill some foes, run back to the bonfire. Kill them again, run back to the bonfire.

Eventually killing them becomes trivial, as a combination of muscle memory and leveling up.

Some might even call that practice.

It's an unwillingness to invest time into practice that hinders people from enjoying more of it, not the inherent difficulty. And this goes for a great many things, sports, music, painting, programming, woodworking etc.

It's also totally ok that people don't want to invest the time -- I'm not making a value judgement here.

For a sports analogy: I don't want to invest time in practicing (or even learning about) basketball. As a result, I'm horrific at it. I'm quite fine with that. It does however mean that a decent chunk of popular culture is inaccessible to me.

I'm not familiar with this so if you can help me understand, I would appreciate it.

From my understanding, one of the causes of slowness in US is waiting for bids. Government related work is required to open projects up for bids for a period of time, review all the bids and document the process. In many other countries, the project goes to the company with better relations to the project manager or the companies with the best bribes.
I generally agree but also the local residents (who do vote in local elections) don't want permitting to be speedy. In fact they want it to be slow because there is a lot of NIMBYism and protectionism around property values. So in this case I think it actually is what voters want.
Well, I can tell it's a programmer and not an engineer who works at hardware levels. All the complaints are "1st world" or "high level" programmer/computer problems.

If you've ever designed hardware and had to bootstrap it up to a "high level" situation - then these are nonsense concerned when you are merely trying to get a new hardware design up and running. You can always bootstrap to a language that already has all these things. The author obviously has never done anything like that. Not based in any reality where C matters.
Looks like their "promise" is worthless.

I've been using Fish for years and spend my entire day working with Python. Python's virtualenv has an `activate.fish` command, I've never had any problems with it. Additionally, we have a ton of internal tooling built in a fabfile, so I've written a couple of snippets of fish that automatically activate that .venv (Poetry managed) whenever I cd into a directory that has one, and also expands a bunch of env vars into the shell session. I've also got this feature request in on the virtualenv repo in the hope that one day we can have activate.fish emit an event - https://github.com/pypa/virtualenv/issues/1456

So if my small country would be neighbor to US we would need to ask US permissions for stuff? If the answer is "sure, for X and Y US should approve because it is so big" then this means that US neighbors are not really independent but vassal countries? If yes, please have your preferred politician admit this.

I am from eastern Europe and I can tell you we did not want to enter in NATO because we love USA and agree with it 100% , we did it to get into this defensive alliance to protect ourselves from Russia. Nobody here wants to sacrifice their live to bring freedom or Western values to Russians, we want to be left alone and we want to be able to do aliances and partnerships without the big bully to veto it.

If you listen to all of Putin speeches and not some cherry picked parts, you will see he admitted he wants to restore the URSS , he started the war to bring back is "brothers" into URSS and this NATO stuff is upsetting him because if he waits until Ukraine or Moldove enters NATO he will not be able to make URSS great again.

Copilot is wonderful, when you use it appropriately. It autocompletes and has a lot of good knowledge of the code.

I had interview that usually lasts an hour and people don't get to do all the code, I did it in 15 minutes or so mostly because I knew what needs to happen and code was autocompleted quickly as I would start writing.

It really helps you focus on what you want to do and don't have to think about syntax or correct variable name.

You still need to be a good developer, but it helps you greatly to do your work.
If stability arrives only in your mid to late 30s, leaving only a handful of fertile years (assuming no prior medical problems picked-up in younger life) then it stands to reason that a women will be far less successful at producing a large family than one in say, her early 20s. For men, I would agree with you. But then the calculation is rather different.

I've just taken Fish for a test drive and I'm really impressed. I use the Starship prompt in Zsh and it worked out of the box in Fish. It appears direnv will too (which I rely on).

What's the point? Surely this isn't an indictment of JavaScript: plenty of languages have concurrency and share the same problems. Is it a warning? It doesn't follow up on the cause of the bug at Facebook that it mentions. It doesn't mention any specific examples at all. It doesn't offer any advice other than "there are synchronization primitives" (which it doesn't list) and "using synchronization primitives isn't enough" (without explaining why or what to do).

Above all else, this has nothing to do with the event loop: these are problems with concurrency, not the runtime.

The high fertility rate in Israel is almost entirely due to the country's Haredi ultra-Orthodox Jews. Among them women are tightly controlled, abortion is murder and birth control is taboo. Consequently, the average fertility rate per woman is 7.1. That's one way of solving the fertility crisis, but perhaps not a good one.
