This guys been banging on about Tesla / Musk for years. See for example:

"What’s Wrong With Tesla? How Much Time Do You Have?
By Edward Niedermeyer on February 5, 2010"

Meanwhile TSLA is about about 200x since then.

Haters gonna hate hate hate...
Will it be open-source, I wonder? It would be cool to be able to use other servers/viewers just by taking the right-hand side after the /. It would also make it more resistant to censorship.
Please don't use this. -apple-system & BlinkMacSystemFont are OK but after that it's just a scattershot list of guesses that will often be wrong. I have most of the fonts in this stack installed on my Linux desktop for various reasons and none of them are the system font. Just fall back to sans-serif for now and adopt future -apple-system equivalents as they become available.
It's different because they stopped making Lincolns, so the clock is running.
Is there an established way that people advertise their open source projects to developers for help? I know that GitHub has exploration features but when I last used them it felt like looking for a needle in a haystack.
I have been told that we tip because servers can't make a living.

If we don't tip, we are killing them.

Why do we tip 20% again? It seems like we can tip 5% and the servers would still make bank.
Do you know why? A mania kills a segment of the stupid, but provides enough capital to the remaining lucky who cashed in early such that they can reproduce where they otherwise wouldn’t have. It’s evolution at work. In the short term.
I agree. A long haul flight in business isn't bad at all.

Now going to and from the airport and all that comes with it? That's a different story...
The author's chief complaint about meritocratic systems is that they are not meritocratic enough, and it's worth ignoring the clickbait title/thesis to look at why. Making our companies, governments, etc. more meritocratic without falling into the traps the author talks about is a worthwhile endeavour.

In general, it pays dividends to take a hard look at any selection process to see if it's selecting for the things we actually want. e.g. In politics, elections do not select for leadership or intelligence. They select for the ability to fundraise, sling mud, and evade justifiable blame. There are no easy answers, but it is worth asking how we can improve how we select leaders.

e.g. Fundraising ability is tied to corruption, which is generally bad for the public good. So, it's worth asking if we can limit the influence fundraising ability has on election outcomes. i.e. How do we reduce the influence of money on elections?
This is a bad law, but this post is a bit clickbaity in the sense that the law is about "presumption" which means it's not inherently illegal. That isn't an excuse for a bad law, but it's a far cry from making the mere possession of six dildos per se a crime. Furthermore, while having bad laws on the books is a very bad thing, we have to ask how many people have been prosecuted and convicted on the basis of possessing six dildos. I don't know for sure, but a cursory search doesn't seem to turn up any cases except one from 30 years ago in which the defendant was acquitted. Again, not defending this law, but the article just seems like an attempt to dunk on the Republican state..which is fine - knock yourself out - but let's have a bit of perspective.
That is one alternative. Another is to pump air down a hose to force water out of a deep cavity. A third is to winch a float down toward a seafloor-mounted pulley. Methods that put the electrical equipment on shore are generally cheaper than the ones that put it at the sea floor.

Energy storage is mostly freshman-level physics (E = Fx, E = mgh), chemical schemes excepted. Undersea methods can often be adapted to an under-groundwater form.

The winning energy storage methods will be the cheapest ones, even at the expense of round-trip efficiency. But forms that are shippable, such as liquified ammonia synthesis, have an advantage than can overcome both higher cost and lower efficiency.

Most places will rely on a mix.

And then there's the output latency of LCD TVs. Seems less of a problem than it used to be, but some older TVs could easily add 50-100ms of latency (particularly if not switched to Game Mode, but even a game mode didn't guarantee great results)

But these days it's hard enough to convince people that 'a cinematic 30fps' really really sucks compared to 60 (or better), and there's an even smaller number of gamers/devs who seem to notice or care about latency issues.
"Client side interpolation" is a term misused in the game world. It's really client side extrapolation. Interpolation is generating more data points within the range of the data. Extrapolation is generating more data points off the end of the data.

Interpolation error is bounded by the data points on both sides. Extrapolation error is not bounded, which is why bad extrapolation can produce wildly bogus values. So you need filtering, and limits, and much fussing around.
I am not sure your take is correct, but this might be because of my personal views: I do think the "stereotypical Asian student" today is indeed discriminated on merit, pretty much in exactly the same way that the "stereotypical Jewish student" was excluded thanks to "holistic" admission criteria in the last century. So I guess on that front I agree with you. But I also agree with the article that believing meritocracy works is silly, given that all meritocracy I have seen was functionally equivalent to classism: the kids that had merit usually (not always) obtained that merit thanks to their parents being of a higher societal class, which enabled the kid to worry about school, not about a second after-school job they had to take in order to feed their little sibling. Obviously my example is a bit extreme, but most of the kids that have "measurable merit", have it because their family has been sufficiently high class to enable them to invest in their merit and grow it.
This has been orthodox economic policy for decades. There's two usual prongs:

- put up interest rates. This raises the cost of business credit, and at the margin, puts people out of work, until employment reaches the "non-accelerating rate" (NAIRU)

- break labour power by legislating against unions, breaking up state-owned businesses into the private sector, and promoting the Uber-style "independent contractor" model where people aren't employees

The public may be exposed to rising food and fuel costs, but if they can't demand higher wages that can't feed forward into higher prices and a wage-price spiral.

Yes, this involves a lot of worsening of living conditions.

There's something really interesting happing in the UK at the moment. We are awash with PE funded FTTP (fiber to the premises) startups, in my town there're two pulling their fibre through the BT ducts and putting small boxes on the top of telegraph polls. We can now get 1gb finer for under £40/month.

It's basically a repeat of the 90s / early 00s, their exit strategy is clearly for a larger player to build a conglomerate out of all of them, just as happed with [lost of small cable tv companies] -> NTL & Telewest -> Virgin Media.

I assume CommunityFibre is one of these PE funded startups, the larger their user base the larger the exit for the funders.
It's different when you're a large company with a legal team doing something not clearly illegal - than when you're a single individual doing something clearly illegal.

You didn't have to have a taxi medallion to be a black car driver and pick people up at locations upon request - which, originally, is what Uber was, exactly.

The whole point of a taxi medallion is to be able to pick people up off the street - which is what these independent drivers at the airport and train stops are doing.
The systems are also different, so that’s expected?
You just described usability! General UX.
Quite the opposite, no? Only by removing unemployment benefits and welfare payments could the general population be coerced into returning to the workforce. However, I think both of us would agree that such a strategy would be one for Congress to implement, not the Fed.

Edit: I'm not advocating for or against such a strategy.
The concept of merit itself is phenomenologically suspect. We don’t live in a platonically ideal world. Merit is a subjective distinction and is thus itself able to be gamed, and it is by those with the means and the gumption.
Oh. I think you’d handle it the same as rest, make a new individual field query for that friend by ID and ask for the pagination there. I think that would be manual work for graphql or rest, im not aware of anything that does that automatically. It’s also not a case I’ve personally ran into so not sure.
Ask HN: Low cost eXtended Reality SW/HW stack for non-affluent schools/students?
What low-cost(as low as possible) tech stack(both hardware and software) is available to develop and distribute eXtended Reality(XR) educational simulation apps(with hand tracking) that can be affordable to students/schools from non-affluent areas(even from developing/under-developed countries)?

On the software front, Godot Engine targeting Android handsets could be one option for developing the apps. But I think this will not be straight forward as some porting will be required to make Godot XR work on low-cost Android mobile phones. What other options are available?

Also, on the hardware front what XR headset would you recommend that is very low-cost?
In early 2006 I asked the original author and the current maintainer for their blessing to use the domain "rsync.net" for (re)incorporating the offsite backup component of the ISP I started in 2001[1].

I gave them right of first refusal, etc., and they said my use of "rsync.net" as the name of the company, domain name, etc., was acceptable.

I missed the use of direct io and the comment about fsync threw me off, thanks. Very impressive then!
Good point. I was comparing to protobufs, which is slower to parse than json. Other formats are faster.
What do you think that the "algorithms" are hiding from you? Do you think that anti-corporate and ultra left wing content is censored on Twitter?
Taxes could work.

Maybe they will push to create a national health system. The poor would go from getting 10-25% of their yearly income from the Feds via various tax give awaysa
to actually paying 10-15% of their income. That would cool the economy as you pass higher taxes further up the progressive tax chain. Most middle class members would probably end up paying $10k per year in new taxes.

They could also pass a carbon tax. Energy costs would double or triple. Suddenly the average home would pay $1800 per month to keep their food from spoiling.

Essentially lock large amounts of money into required bills.

Edit: even if 1800 is on the high end, the cost shock of taking an apartment with $250 per month to 500-700 will still put a huge cooling effect on inflation. And yes, large portions of the United States need A/C and more will to cope with climate change. Also think of the cost to businesses of all sizes. Keeping offices, showrooms, and other such buildings will limit hiring and pay raises.
Don't get me wrong: the reason why both Node and Deno (and probably JavaScript itself!) are so successful is that v8 is a ridiculously good runtime, and libuv is great.

Deno did something smart: all the non-web-compatible APIs are under the Deno package. That's great, and almost fixes the issue I am highlighting.

If Node could do the same, and provide a way to find at "compile time" (that is, statically), if a package is web-compatible or not, that would be very good.

My issue has probably more to do with npm than with Node itself.
I agree with you broadly.

I think it's important to consider though that what we have right now isn't a demand crisis but a supply shortage. There are, thanks to all sorts of reasons (the fallout of COVID lockdowns from 2020-2021, supply chains, war in Ukraine between an oil exporter and a grain exporter, COVID zero in China) not enough things available for everyone to buy.

The amount of money folks have and are being paid - and are demanding at new jobs - cannot turn into the same quantity of goods now as it would have two years ago. Hence rising prices.

One of two things can happen:

- We can increase supply of goods, fix supply chains, infrastructure, bring in more labor, etc.

- We can decrease demand by reducing the amount of money in the system (increase interest rates, reduce wages).

But like, one or both of these things have to continue to happen until the demand for goods and services matches the available supply of goods and services.

Yes, this may lead to worsening conditions but that's because we don't have enough stuff for everyone to get what they want right now.
There are plenty of other vehicles. Yes, the limo companies liked the unibody limos but there's no shortage of different models they can use. I'm certainly not especially picky in general.
There's more than enough bad businesses that only exist because the price of debt is less than inflation thanks to the Fed.

As soon as they stop egregiously manipulating the price of debt - those businesses will fall like dominoes.
Some heretics were/are complete loons. But there’s an insanity in the religious devotion to “Science” in popular culture driving the word to take on a synonymity to “orthodoxy” or “establishment”. “Trust the orthodoxy” wouldn’t have nearly the same ring to it, but that’s what I think I most often hear from people wearing cheesy Bill Nye and NDT t-shirts. Calling someone “anti-science” then also sounding like “anti-establishment”. Sure they may be, but insofar as the scientific method is concerned, we need antithesis ideas, loon hypotheses, and room for those to be tested and discussed.
It's definitely gotten better but there's still questionable overabstraction in certain standard libraries and/or popular frameworks (such as Spring).

For example, in Java, to create a Trust Manager for certificates, you have to first call a factory method to get a TrustManagerFactory, before I can even get a TrustManager: https://docs.oracle.com/javase/7/docs/api/javax/net/ssl/Trus...

That's just really weird and confusing design.
Very cool. Anyone seen a mod that adds activated carbon? A lot of DIY filters are very cost-effective, but the lack of activated carbon is a big downside compared to commercial solutions.

There's really only two air cleaning technologies that are worthwhile right now:

- HEPA filters (remove PM 2.5 particulate and above).

- Activated carbon (neutralizes harmful gases).

The only other thing that may be worthwhile is a pre-filter, but that is mostly a cost saving measure rather than actually improving air filtration.

Unfortunately commercial filters are full of gimmicks that don't work or may even be harmful due to Ozone generation (e.g. Ionizers, UV lights, et al.).

Why not use Valve's game networking stuff? Just curious.
I recommend adding telemetry to your project for this (and I know a lot of people feel strongly about this, so I'll add: with a very easy way of disabling it).

In OctoSQL[0] I'm literally just sending JSON files with coarse information about 1. invocations of the CLI, 2. features used in these invocations, to a VM on DigitalOcean (with a 10-line server receiving them and writing to a JSON file - which I can then process using OctoSQL itself).

Thanks to this I knew that until recently most of what I had were stars, not actual usage, and could also see how the big rewrite I released in January (and the following updates) made a lot of people start actually using it since. Very nice feeling :)

All telemetry logic in OctoSQL is actually contained in a single short file[1].

PS: Keep in mind that https requests take a long time, as they need to do a few roundtrips for the TLS handshake. Don't do that on every invocation if you have latency-sensitive invocations. I.e. in OctoSQL I'm only sending aggregated telemetry data every 10 invocations (as well as on the very first one).

Lamdu – towards the next generation IDE
You only care about the latest state for some events. Only events which will soon be superseded by a later event should go over UDP. Move A to X, sent on every frame, fine. Create monster at Y, no.

If you find yourself implementing reliability and retransmission over UDP, you're doing it wrong. However, as I mention occasionally, turn off delayed ACKs in TCP to avoid stalls on short message traffic.

Reliable, no head of line blocking, in order delivery - pick any two. Can't have all three.
The problem is that this has been policy for decades. Their job losses mostly affect the lowest earners. Giving us higher income inequality. They need to figure out policies so that they don't just negatively impact the bottom.
If you don't care enough about a certain art form then you'll never search deep enough (and most of the times it's not even that deep) to find the good stuff.
This guy spent a few of his points talking about music. What does he listen to then? Is he passionate about music? Is he knowledgeable? Or does he just like music in general and listens to the radio and his Spotify library?

Of course if you have a superficial interest you'll only get fed the mainstream bullshit. But is it seriously that difficult to peruse the cinema's pamphlet and choose some quirky movie near the bottom? Is it that difficult to peruse your radio spectrum and find a station that features more indie musicians? And how about doing some actual research on the internet once you find that quirky movie or that indie song? Maybe you search for the director or the singer, you discover a new genre, you find a forum somewhere and deep down the rabbit hole of incredible new stuff you go.

This post screams Gell-Man amnesia to me, I'm sure that this guy is passionate about a topic and would cringe if I said that everything about his favorite passion is mainstream and indie content is disappearing.
> The author's chief complaint about meritocratic systems is that they are not meritocratic enough

Why do you say this? According to the author, "merit itself is, in large part, the result of luck. Talent and the capacity for determined effort, sometimes called ‘grit’, depend a great deal on one’s genetic endowments and upbringing."
I do not think you are presenting the strongest critique of meritocracies in your imagined counter argument. Similarly to you, I like the idea of meritocracy for the reasons you outlined in your first few sentences.

However, in practice meritocracy frequently devolves into classism: yes, the hard working kids of the families of higher class would be awarded more than the lazy kids of the same demographic. But the kids of the lower class would not have the same opportunity to invest in and grow their merit, because they would have to worry about taking a second job to help feed their family (or less extreme examples). I do not see a version of meritocracy in the USA that is not at least partially also classism, given the current state of the social safety nets.
And I explained it because (as a native BrE speaker as I suspected the one you replied to was) it didn't have any such ring to me at all, it read perfectly naturally.

(I have seen Arrested Development fwiw. Didn't care for it, but I've seen it.)
Indeed, I agree! I will definitely be open sourcing this in the next week or two. Right now it’s all spaghetti code proof-of-concept (wrote most of it on my iPad touchscreen on the couch…laziness?) but I’ve already started cleaning and standardizing the pieces to be able to open source it all.

The key piece will be the parser module + block component set, which I plan to release as a standalone package, so any app could render these Memlink strings natively and easily.
VCs are generally not risking their own money these days. They raise funds from many other people, and sometimes that includes <gulp> pension funds.
I’ve written a diffing algorithm using UDP. You tell it to diff against a previous packet with an id. Every so often you send a full key frame packet so they always stay in sync and have full game state.

Right. That's how video streams work, too. Every once in a while there's a complete frame, but most frames are diffs.

Wow. Well, if you're going to define both abortion and human so expansively, I can't say I have much sympathy for your position. What about all the extra fertilized eggs produced via IVF? Do you think the ones not selected for implantation are "aborted" as well?

Cloning of human cell lines for various purposes (especially therapeutic) is going to throw a monkey wrench into your definitions, with "humans" flushed down the drain wholesale every day, as a matter of course.
> emoji have their own font

That’s not true. Emojis are Unicode characters just like `a` or `ß`. When I type <an emoji character> on my computer it doesn’t magically change font in the middle of the sentence; it’s just a character.

edit: looks like HN stripped away my emoji.
