And while too rich for most is one way to look at it, another is that $1K would not even buy you a proper monitor all that long ago, and that this is a very low volume production. I think the price point is actually quite impressive, I expected it to cost substantially more, especially given the BOM, there are some pretty impressive bits on there, and those connectors and PCB are also not exactly free.
This has been one of my major gripes with the Oculus for over a year now, and one of the main reasons I don't use it much anymore. My son uses it extensively, and knowing that we're stepping on each other's progress in a game have always made me care a bit less about playing. I wouldn't have thought it would matter that much, but the specific thought has come up when I thought about using the headset and kept me from using it, so I guess it does.
I sometimes think of how Earth is so OLD. It’s a third of the age of the Universe. That is just mind boggling. While I have trouble mentally grasping ages on the magnitude “billions”, I do know what a third is. It’s a very sizable chunk. And for this very old thing with life as you say very early — it’s crazy how we’re here only now. The sample size is small though. I have no idea if quirks on the path took evolution unusually long or if we’re early, or what. Still, yes, this is something to consider.
Another example of how IP laws have become an enemy of the goals society had when passing them, which is not to enrich a few corporations but to incentivize innovation, but now it is clear copyright, and patents today are doing far more HARM to innovation than they advance it

As such we as a society need to look hard at those laws and policies to reform them

Sadly the large corporations have a huge amounts of lobby money and are rapidly attempting to get the terrible IP laws codified into complex international treaties to ensure no nation can do any reform at all

I think they already do quite a bit of this, which is probably what makes it puzzling when tech oriented users on hn keep reporting how terrible it is, thus the desire for more details to see whether it's just an older anecdote, something missed in testing, etc.

Two matrix blog posts[1][2] from the past 2 months both mention new user testing/research, and there's definitely more if you go back in their blog history.

> You could certainly build Facebook as a fully server-rendered PHP app, but that would hurt Facebook's business because its servers would need to do more work and its users would have to wait longer for content.

I think they do that mostly because for the users who’ll have to download the header 100 times for each action they’ll do. Not really sure that all benefits from SPA are hidden in company costs. Mostly they are in modern tech approach.

Writing this I still agree with the article. SPA is needed when you are under authentication but publicly you can live with progressive web.

I wasn't able to find what time setting the AI was trained on, but I'm a 1400 bullet player and at that level it is uncommon to resign even if you are down a minor piece and a pawn (or more, but in a good attacking position). The probability of being able to win due to time/a blunder is quite high.

I even saw an IM vs. NM bullet game the other day where the NM was in a losing position but stayed in to grab a stalemate: https://www.reddit.com/r/chess/comments/kwoikt/im_not_a_gm_l.... Not sure if Levy was being unsportsmanlike to stay in the game despite being in a losing position, but even at a high level I think it's normal to play to the end if your opponent is in time trouble.

Also, SPA and server side rendering are not mutually exclusive. Both make sense as performance optimizations depending on the context.
Business, as I believe parent meant it, incorporates parts where people communicate; I suspect though that the parent would mostly say that business is about money.
Maybe so, but that is completely irrelevant for now.

I have been able to convince quite a few non-tech friends to use Signal, but that would have been impossible with Matrix.
The first and only rule of business is that: You are there to make money. Everything, and I mean everything is secondary. Employee wages, whatever 'solution' you're aiming to market, those are all secondary points to the fact that you are there to make money and do what works to get money.

It's a harsh reality, but it's very much the case and it's the first thing you learn on any business course.
"Surveillance capitalism’s products and services are not the objects of a value exchange. They do not establish constructive producer-consumer reciprocities. Instead, they are the “hooks” that lure users into their extractive operations in which our personal experiences are scraped and packaged as the means to others’ ends. We are not surveillance capitalism’s “customers.” Although the saying tells us “If it’s free, then you are the product,” that is also incorrect. We are the sources of surveillance capitalism’s crucial surplus: the objects of a technologically advanced and increasingly inescapable raw-material-extraction operation. Surveillance capitalism’s actual customers are the enterprises that trade in its markets for future behavior."

This. When I get blank page instead of content - I usually ignore the site completely. I do have first-party JS enabled, so if the site is actually JS built SPA and it serves its own JS then it renders normally without me noticing anything. But when I have to elaborate which of the fifty 3rd party script serving servers I need to enable I gladly skip the whole site. Happy to see I'm not alone here.

in my experience this is a formal version of "why the fuck should we pick you among the other people out there"

possibly because..

- the role you're applying is aligned with your intended career trajectory

- you're aware of their problems in xyz areas and you're looking to actively contribute

- you're aware of their competitor's edge in xyz areas, how much this company you're applying for is lagging, what steps could get you guys from point A to B, what metrics and time-frames you guys should be focusing on, etc etc

you wanna be conveying trust, intelligence, reliability and consistency [0]

while this is you qualifying yourself to them, keep in mind that you should also be pre-qualifying them e.g. is the offer / location / hours good, is the role restricting or expanding your skillset, etc

1. it might be covered in sediments requiring expensive movement for little gain (and how do you know where the iron was/is?) and 2. the structures that don't get covered rust away and turn into dust that erosion distributes over large areas. Post apocalyptic societies will be able to salvage iron here and there for a long time, but will it be enough to cover our planet with railways and kick off a new industrial revolution?

Also, the iron was only an example. Coal and other fossil fuels we can only burn once, then they are gone.

Not everyone builds a site to immortalize content. Some are building businesses and trying to move fast. If an API can serve a website, mobile apps and desktop apps, then maybe that’s the only server I want, I move the rest to the client side. If in 10 years I’m still going, then I’ll keep the websites/apps available. If not, I likely will be too busy failing to care about content archiving. If keeping content on the internet was my goal, I’d build my site what way. But it’s not. Providing useful services is.

I wonder if brick and mortar stores are worried about their place of business if they fail? Not likely.

The internet is diverse, some things will be archived, some won’t.
Those are the two most well known options, yes.
I usually navigate the web with javascript disabled and encounter this a lot with articles that require scripts just to display words on a page. A really weird example of this is engadget articles. They display an empty page if you have javascript disabled. The only reason why is their css has the html tag set to display:none. If you uncheck that css prop in the dev tools then the content appears normally. Weird choice on their part.

> that has nothing to do with the principle of banning people from society based on legal speech

Your comment is bizarre and nonsensical. No one has been "banned from society" based on "legal speech", a meaningless phrase.

A lot of people have been banned from using specific internet services because they used them to make threats of violence, or to tell dangerous lies about COVID.

This isn't "banning them from society". Get a grip!

Also, we are talking two classes of people here:

* people who work against humanity to spread COVID-19 based on a pack of obvious lies

* people who wish to violently overthrow the elected US government based on a pack of obvious lies

and frankly, these people can get fucked. They are destroying the country and the planet, and they deserve every single penalty the law can give them.

If private corporations, which Republicans claim to love, use their perfectly legal power to stop doing business with horrible psychopaths, then good for them.

One side went crazy, and now we have to choose sides.

Are you on the side of the delusional hateful lawbreaking violent psychopaths, or with the majority?

(My theory - you are not with the majority.)
I havent heard of any claims that segwit and LN would be sufficient. It is very clear mathematics that they cant scale far. However they provide safe way to scale for short-term. Long-term solutions have to be found. If they are not found there is thousands of shitcoins claiming to solve the scalability issues better.

Google already archives pages for search in spite of their JS requirements.

If archive.org isn't doing the same, that's a bridgeable tech gap.
Depending on the type of ads being served that cross-profile-pollination could lead to info leakage and problematic and/or weird situations. It makes me want to be able to build a fake persona rather than a ghost/anonymous profile
Interesting. I will keep an eye on this. Two comments though: trying to handle corporate actions, instruments, pricing, risk as well as settlement in one library might be a bit too ambitious. Maybe it would be better to focus on just the pricing, or the risk part of things?
The other comment, is that I would probably split products from the pricing. I looked at one of the product definitions and it seemed to be intertwined with pricing. Products and pricing can both be complex in an of themselves, and they are not necessarily conceptually coupled. Just my two cents.
We're talking about mostly-text-pages which have no sensible reason to rely on JavaScript to render, not rich webapps. In these cases I consider the text to be a meaningful representation for the purposes of indexing or archive.

I don't agree with this:

> Search engines and archival tools can handle all this very well today.

I think most developers have been in a situation where they had to explain to users that a moon on a stick isn't easy just because Google can do it. It may be commonplace, but it's not easy or cheap.

The difference between real HTML and JS execution is orders of magnitude of time, expense, maintenance, and stuff to break. That really can't be underestimated. It's the difference between a 500 millisecond call to curl and a whole headless browser and a 5 second wait.

I hope you don't think I'm putting this too strongly, but this raised bar is a force in the monopolisation and de-diversification of the web.
It's not legal when those companies are a duopoly and the agreement is (at least partially) about dropping competing products.

Is there no other way to convert existing ext4 filesystems to use the new structures?
Comic books will start to make sense on eink
I wonder if that could be triggered even when the certificate chain is not validated... you could MITM yourself (for example, using Fiddler) and make Chrome think it's downloading files from the real origin. In that case, an attacker could do that from multiple IPs and force Google to flag your whole domain.
The linked article from 2019 is someone's trivial analysis of why Chrome based browsers became popular; then a rant about the evils of google. The only reason given that I have a "moral obligation" to use firefox? because it sucks slightly less than it used to?
If you use your phished credentials immediately (e.g. inline with it being phished), then it doesn't make a difference if they are using 2FA. You use the credentials they entered to login from a backend system automatically, and then if that ends up with a 2FA prompt, you show the victim the 2FA phishing page next, instead of redirecting them to the real app/whatever.

This obviously does have its own downsides (you have to maintain a login infrastructure, as well as your phishing infrastructure), but this was even seen before 2FA became common to detect if an incorrect password was entered into the phishing site.

It is definitely an improvement, but TOTP doesn't provide much protection from phishing, and as it becomes more popular more phishers will need to accomodate for them in their campaigns, further reducing their effectiveness here.
Right now, she is apparently an activist. There is nothing wrong with being an activist. However, IMHO, being a "data scientist" is inherently incompatible with being an activist. No matter how qualified you were, once you became a passionate activist, you are no longer a "data scientist" or a "data analyst" or a "statistician" on the topic. Again, there is nothing wrong with being an activist, but you can't be both. I feel this is so obvious that requires no further explanation, but I might get massive downvotes for saying this.
Thanks! Any views on the relative strengths of each would be much appreciated.
The most important thing is to avoid proprietary services and uses OpenSource alternatives instead. Like, avoid AWS Aurora and use PostgreSQL instead.

That will make it almost trivial to move from one provider to another.
I agree - that’s a whole separate argument though. If the argument is contextual vs personalized, personalized wins imo
Here's an article from 2011 doing Moore's Law extrapolation of RAM and disk prices: https://antranik.org/using-moores-law-to-predict-future-memo...

RAM, 2011:
"A single 8GB stick of RAM is about $80 right now. In 2021, you’d be able to buy a single stick of RAM that contains 64GB for the same price."

Disks, 2011:
"The price of a 1-terabyte hard drive is $80 now...

In 2013, a 2TB drive will be $80.

In 2015, a 4TB drive will be $80.

After that the doubling rate may lengthen to 3 years instead of 2 years so..

In 2018, an 8TB drive will be $80. And finally in 2021, for $80, you’d be able to buy a 16 terabyte hard drive"
I remember trying the bridge but it wasn't working entirely well, has this changed recently? That's going to be another great integration if it works well.
Weird how the conclusion is that the sites are wrong, not that curl is an insufficient tool for indexing the modern web.

Google search hasn't died because sites use JS.
The universe flying apart and cooling doesn't contradict Penrose, it's part of the theory just to address that point. An infinite structureless, massless universe is a singularity, or so the theory goes.

Assuming this was "settled" (whatever that means in science let alone theoretical physics), mavericks like Penrose are frequently proven right. 'Kuhnian' paradigm shifts are the norm in science, particularly in a field like this. Expect many more...

The New York Times Is Worried Kids Are Gaming Too Much During the Pandemic
Ok you are extrapolating your experience to millions of others in the world. Nothing wrong with that but it isn’t going to give you universal insights since you’re a special case.
> There's certainly some companies that are caught in the hype and build a SPA app when they would probably be better served with a simple PHP site

Yeah, like your example, Facebook. Ever since their redesign, I've switched to only using the mobile+noscript site (on desktop), because the SPA version is resource-hungry to the point that it regularly DoSes whatever browser thread it gets assigned to and has UX that, ironically, seems to be terrible as anything other than a mobile app (they've replaced text with abstract square "touchable" buttons and introduced airy spacing everywhere that allows you to see maybe about half a post per screen).

It's as if its designers have been trying to ram their mobile app down my throat for years (by nagging screens at first, and then by outright removing the ability to view private messages from the mobile page - except sometimes by refreshing sufficiently many times you could trigger a bug and still drop through to the old messenger view, adding insult to injury), and when I still didn't bite, they decided to replace the whole service (which up until then had been one of the last remaining decent mainstream websites) with a facsimile of one.
Ok, so you want to disable tracking and ads.

Why does that necessitate disabling all JS? You can enjoy the performance of an SPA while selectively disabling tracking.
I really feel the article's quality would greatly improve, focusing on just Ethereum 2.0, where fair points regarding its issues are brought up.

Showing the node count for BTC and making it seem huge, while trying to sell the fact of how terrible it is to run a ETH node instead, and not mentioning the fact that there are actually more active ETH nodes online than BTC, is highly disengenious, and unfortunately just makes this seem like a bagholder trying to discredit competition.
