That's true, he is. (I forgot that in fact.) FWIW I've never discussed Reddit with him, and there's no pressure to moderate HN any particular way about these things. Our job at HN is to keep the community happy (er, as happy as possible) and to make HN as good as possible. Those are the things that make HN valuable to YC.

It should take only a brief glance at https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que... to decide whether HN is protecting Reddit - the last two weeks have seen a tsunami of threads, almost all negative. Discussion of OpenAI isn't that lopsided but I wouldn't call it positive. sama isn't involved with YC in any way as far as I know. (Edit: I just asked, and it's a bit more complicated than that - he speaks at batch events occasionally, has ownership in past funds like most former employees do, invests in YC startups sometimes, etc.)

I appreciate the reference to good faith! that is kind of you. FWIW, the reason we don't mark titles as edited, or comments as edited when commenters edit them, or any of that kind of thing, is because HN's UI has always been minimal and in particular has always avoided ceremonial or bureaucratic trappings. This is the sort of quality that dies by a thousand cuts if you start adding details, and I don't think that would be the right tradeoff. It's just not in the overall spirit of the site. That doesn't mean we're trying to hide anything—we're always happy to answer questions about anything on HN, and I spend most of my time doing so.
I had a restaurant owner out me by name in response to a Yelp review. I pointed out that her attitude toward customers like me tells the world everything they need to know. That place went out of business, guess it wasn't just me.
I'm not sure how this interacts with temporal tables, but I know that I've run into issues before just trying to track something with a high watermark, in that long running transactions might add records "in the past" behind your watermark that you track, so you need some mechanism to make sure you're capturing those (i.e., you can't just track an auto-inc primary key). Unfortunately, I think CDC is really the best way to handle this.
Yes, Linkedin is a professional social network, but no, you will not find high quality content there.

There's a lot of value for keeping in touch with the zeitgeist (ex: sqlite innovations, llama etc) and finding new trends on HN

There's about 0 value from using linkedin.
Why worry ? It's already guaranteed to be the case. Apps will not have direct access to the cameras, meaning that the Vision Pro is destined to keep being a toy fully steered by Apple. You also cannot access any depth information, or anything that would make it useful as a general 3D computing device. You can't access eye tracking, so say good bye to foveated rendering. And since you can't have foveated rendering, well you're now rendering 2x 4k images on a relatively underpowered device.
I agree on having the luxury of budget being a thing, since only large companies have that.

I think though you're lumping together both the inexperienced and the stubornly dumb, and by that I mean those that aren't humble/flexible to learn from experience. It's crucial to filter out arrogance that can't be taught so you don't poison your workforce.
HN readers are the human equivalent of ChatGPT?
Round Two? There Is No Round Two
It's interesting that you mention Real Estate, because Vitalik's solution is inspired by the "Land Value Tax" idea in Real Estate, which is a policy widely supported by economists as the "least bad tax" and which directly attacks rentierism and land speculation, which are the direct cause of inflated land prices and a significant contributor to the ongoing housing crisis (as well as inflation overall, as rent inflation is a major contributor).

Fun fact: the problem with domain names has happened over and over again in a related field -- online games. In fact, wherever you see a "land like asset" arise (defined as an asset that is scarce in supply, necessary for production, and which obtains value from its location), you will see something analogous to land speculation. Digital "land value taxes" have been attempted before, and the best evidence available suggests that they are very effective:

https://progressandpoverty.substack.com/p/land-value-tax-in-...

Right now in domains some services have a very, very crude approximation of a "land value tax" where they charge a fixed higher fee for "premium" domains (common words). This has a slight effect on dampening speculation, but the root problem is that the fee is not directly proportional to the desirability of the domain (ie, the location). The solution is not a blanket high fee across everything -- it's perfectly fine for the holding cost fopr things that aren't currently in high demand to be eeffectively zero -- it's to have a holding fee that rises and falls in proportion to demand for the non-produced, necessary asset.
Lemmy apparently has controversy with its developers, with Kbin being given as the alternative. So you could look into Kbin aswell.
> The last thing that bugs me is peoples claims the new mods (if chosen by reddit employees) wont be as high quality as the previous ones. No one has ever proven the current moderation teams are any good.

There is some competition between subreddits for attention, and a bad mod team can cause a subreddit to lose that competition (including to subreddits on different subjects), so there is some amount of successful community building that must have happened.

Certainly Reddit's setup does incentivize name squatting, but there's been plenty of cases where the obvious name is run by a team so ineffective that it gets outcompeted (r/marijuana vs r/trees, r/lgbt vs r/ainbow, r/moddedmc vs r/feedthebeast are some examples). And plenty of communities get by with non-obvious names, like r/DestinyTheGame, r/Pathfinder_RPG, so it's not purely a name race.
Great summary. Multi-node relational DBs are very much double-edged swords. This article mentions the potential data loss during failover events. I've complained in the past that Heroku Postgres advertises HA like a strict improvement and leaves the actual failover mechanism in the very fine print; the standby master is async, so you can lose data. There's no free lunch here, you either tolerate some data loss or tolerate extra latency before commits.

When you get into sharded DBs, a lot of limitations aren't obvious at first. I've used Citus a long time ago and Spanner much more recently. Spanner feels almost like NoSQL: Each table is like a distributed KV store. Indexes are just tables where the PK is the indexed col(s) and the val is the main table's PK, though you can also store additional cols (aka denormalize) in the index to avoid an extra join. You can't combine two indexes to filter on two cols; you need one composite index. More advanced things like order-limit, WHERE (NOT) IN, and subqueries tend to be slow. The query planner is pretty limited, and often I just force things. You also have to really know what you're doing with the pkeys. Which is all understandable, given its requirements.

I forget the limitations of Citus ACID, but they're significant. Spanner has full ACID, but even basic operations are quite slow. Single-node Postgres actually doesn't have full ACID unless you put it in the slower SERIALIZABLE mode, but you don't really need it.

I agree with those who say it's better to focus on sharding at the application layer if possible. If you can't do that, it's probably due to the underlying nature of your problem, in which case sharding at the DB layer in an efficient way tends to be even harder. Sometimes it makes sense, but it's not magic.
I’ve just learned the Vergence-accommodation conflict [1]. VR/AR, from now on is a no-go for me. It never came to my mind that those headsets had such a problem. We’re talking about an accommodation distance of what, three centimeters? I’m already on my way to reverse my myopia, sorry, I can’t take an even more unhealthy visual environment [3]. Half of the world is already on its way to be myopic by 2050 according to research [2], and keep in mind this is only the effect of smartphones. You don’t exactly hold them centimeters away from your eyes. I’ll stick with my plans of buying a projector if I ever want giant screens.

But how will it deal with nulls? For example, let's imagine I have a user schema. This schema has 3 fields, username, is_admin and admin_level. I can guarantee using changesets that when is_admin is true, admin_level must be non null. When is_admin is false, it can be null. admin_level would be always treated as nullable by the type system?
How do you go about doing the mechanical drawing for a footprint not found in the library? I tried to design a simple SD card board as a learning project. I gave up when the part that I selected was difficult to draw. I was not sure whether I was missing some information or is it my inexperience. My persistence on learning and eventual failure left me with the bad taste.

PS: The part I selected seemed to be a generic brand and did not get any info to clarify the dimensions.
> In many ways, the AVP can be seen as the “Meta Quest Pro done much better.” If you are doing more of a “flagship/Pro product,” it better be a flagship.

Ok. I'm fine with being told "you aren't the target audience" but... name 5 things I would do with it if I bought one.

Why would I put it on my face/what would I gain from it?

Gaming? Productivity? What can it do that a screen + monitor + mouse + keyboard / iPad / iPhone can not?
There is already a large population of bots reposting formerly popular content, including the comments from the original thread. It’s eerie once you notice it.
This tracks exactly with what I've noticed.

r/fragrance for example decided to stay open, but the mods just would quit doing anything. That'll show us!

What happened: no spam. A few silly posts. A lot of good posts. A lot of people remarking how much better the sub is without mods. Mods returned, promising to 'consider community feedback' once they realized they lost control of the narrative.
If anyone would like to try reproducing the bug, I have a fairly solid reproducer here:

>"you won't be able to run powerhouse apps from macOS to get your more serious work done".

There's nothing to suggest that powerhouse apps won't be developed for visionOS. The hardware is capable and at this price point it seems that the point of apple's hardware+platform is for the Autodesk/Adobe/Avids of the world to bring 3D-first workflows to professionals.

At the moment we use flat 2D paradigms to design 3D output. The VR era provides developers the opportunity to shed 2D design paradigms and operate directly in the third dimension.

If the objective is to just run 2D macOS apps on VR hardware, then VR is nothing more than an expensive novelty. A VR headset can be so much more than an expensive alternative/second display.

What VR is missing is "Developers developers developers", and attracting developers requires significant investment and commitment to a platform, not just a product.
What are the current use cases for AR?
I assumed Yelp reviews can't be trusted from day one. It's obviously a huge target for gaming and scamming, pretty much any review site is. I include Angie, and similar sites in that as well.
You can do VSCode Remote in a browser on an iPad so I'm not too worried.

I think the bigger factor is that Apple is trying to push this as more of a workplace productivity machine than the iPad, so third party developers will hopefully be more amenable to porting those types of apps than they were to iPadOS.
Another danger here is testing with the website being the only thing on the PC: some people use their computers like that but many others will have many different things open at once: just because it can run at an acceptable FPS on the detected hardware doesn't mean the resource use is acceptable on a system which is multitasking. I usually have >100 tabs in my browser and at least 20 of which are loaded: they cannot all demand what your site demands, even though the hardware is quite high-end.
Isn’t this cause for defamation? Or is it protected under article 230?

Even if it’s not yelp doing it the fact that they are publicly advertising the reviews should make them culpable.
Honestly, just use Spanner. It's the perfect database*. If you need to trade freshness for savings, put a cache in front of it.

If I were building a new startup in 2023, I would need a mountain of evidence against using Spanner. It's ugly that it locks you into GCP but hey an iPhone locks you into Apple's ecosystem, that's just the price you pay to get good things.

* unless you need timeseries, columnar, FTS, geospatial, graph or something special like that
Macs have the best of both worlds: consistent menu bars with built-in function search.
The question is: will that still be available after the API is paywalled?
There certainly is content. Often the ones I could find two years ago but now cannot.

That's because the web is full of juvenile sub-normie content such as geeksforgeeks (if you consider programming topics for example). It shadows the very specific queries with highly SEO'd Juvenile stuff.
I watched the event. Timecode for this specific claim, please.
Clancy Brown or Glenn Fleshler (True Detective season 1) probably come closest in my view. Another one, if he were younger and bulkier, and hairless, who I think fits best with the book's overall description of the Judge would be Sid Haig.

The important aspect of an actor for the Judge wouldn't just be his physicality and baldness, it would also have to be a certain very particular type of sinister air. Few large actors have that.
That’s an insane way to think about your fellow human beings. “Dump them in the desert?” Really? (Sadly not uncommon, though.)
Well, my downvotes are well deserved, asking such a question here.
Love Bobby B videos. Second that recommendation.
secrets can't be kept in any large corporation therefore this is a conspiracy theory

of course secrets can be kept in large organizations, but it's funny how often that get repeated.
API for the content I write? No thanks. It takes a few seconds for a scammer to copy the content and apply their *** referral links to my content.

Let's remember that OpenAI made part of the profit thanks to the data they acquired from crawling the websites (not directly by OpenAI, but some other parties).
I hope reddit dies and we get a great migration to new smaller forums all over the internet. We need to stop consolidating the internet.
I’ve seen a lot of arguments that users are the folks who provide the value/ content of Reddit and so somehow Reddit must respond to their wishes.

And I like that idea, a great deal.

Although I have to note that users have given Reddit that content to use, for FREE, and continue to do so. They do this elsewhere too, including sites where they say don’t like the site administration, Twitter, etc…

So I’m not really sure how this plays out.
The propaganda for the Vision Pro is somewhat similar to various crypto bullshit in the past years: "you're not seeing the vision", while it stays a mostly useless tool.
The name Courier Inbox is really unfortunate given the Courier mail server.
Foveated rendering is supported by default. Most apps will rely on the OS's renderer and not their own so they don't have to do anything with eye tracking to have it enabled.

EDIT: See cma's comment below which adds more info: apps that use their own render still support foveated rendering too.
Evidence for the utility of quantum computing before fault tolerance

Interesting to see if this helps speed up the utility of quantum computers
Seems very conspiracy

I don't think that in 2015 MS had known the AI explosion of the last months, at such degree to base a whole product strategy
Yeah I find it a bit hard to believe. If you really think reviews are inauthentic it’s not hard to click on their profiles and see. I find it hard to see much evidence for astroturfing. If anything I think it’s fairly generous about not putting negative feedback front-and-center.

That, and, as the article details, and I’ve seen in my own personal experience, business owners are extremely aggressive about trying to get you to take down negative reviews, which I’m sure not only gets people to take them down but also discourages people from writing them in the first place.
Most of the value of Google is the services it provides (search and ads, and indeed cloud, which is a separate product and not just "Google's internal fabric exposed") on its internal fabric.

Splitting out "Google Services" from ads or search creates a company with one customer (or two, if we've split out ads and search) that is basically in no market position to get more customers because Google's internal fabric is not a "cloud offering" (source: I was listening in when the company decided to offer Google Cloud and not make that "just the bare metal we run everything on;" Google's internal bare metal is too developer-hostile to the common way things are done outside Google to be a viable product).

Meanwhile, search and ads would be in a place where there was only one "cloud" company in the world they could run their product on.

For all its money, I don't believe Google could afford to re-tool their products to work on someone else's cloud, so once the "Services" company foundered for being unable to compete / having a monoculture of customers, the ads and search companies would die for lack of vendor offering the one bespoke cloud model they can run on.
We have a sort of meta-stable failure here.

Even if it's possible to win the battle against SEO and junk sites (and I don't think it is), this is the best that commercial search engines will do, given their resources and incentives. No one else has been able to break in, for lack of quality, for lack of resources (it's expensive to index the web!), and b/c search engine brands are so sticky (that's why Google pays Apple ~$10 billion to be the default on Apple devices.)

If the junk web problem was so easy to solve, wouldn't another search engine be able to do so - like Bing with Microsoft's resources, or DDG with their unique outlook/guarantees?

So given the current economic system, the current governance regime, and the current culture, this is the best our civilization can do. Unless there's some sharp rift, the internet will stay the course.

I feel like this line of criticism feels a bit like screaming at the clouds.
I think this is a little uncharitable to kids. Do you not remember the stressors and ruminating thoughts of childhood? To say nothing of children who have experienced trauma. Perhaps this could apply to pre-object-permanence infants, but by the time they're undergoing surgery (hopefully...) they've had years of conscious experience.

Hopefully I'm not being too uncharitable, your idea is certainly plausible. I'm also just musing which feels disrespectful to the terribly interesting expert take in the ancestor comment, but I cringe whenever I hear arguments that I can reduce down to "being a child is not at all like what it is to be me", as it's been used for centuries to suppress their behavior and excuse abuses
Exactly! There is a market for something that more closely replicates conversations in a bar. Sometimes you want to be a blow-hard and say some crazy shit without it being indexed for all eternity.
The article doesn't equate "dumb" with "inexperienced". It equates dumb with "makes wrong and dangerous decisions".

In this context, you probably do not want industrious people who will consistently make mistakes and create more work and a mess for others to clean up. The dumb also do not learn from their mistakes -- they are not simply inexperienced.
Extended time fixed focus creates eyestrain. In a monitor environment, people look up, they look around, they look elsewhere, and so on, and even so monitors cause eye strain.

This is not a controversial take. Yes, there are tech bros who will insist that this is all fine, but the actual feedback from the majority of the population is that extended wear of pretty much all VR helmets anyone has bothered to look at causes the same eyestrain issues.

There are always people who will put up with discomfort or for whom the discomfort is relatively lower (or they are younger and it is less of an issue), but these products are not going to replace monitors. Resolution is not the only issue, just the one that is most notable when you first put the helmet on.

In addition, the weight of the helmets is an issue. Extended wear is a problem and one of the few notable, repeated comments from the carefully-managed 30-minutes-max Apple Vision Pro demos is that the weight started to get annoying. Seated demos under 30 minutes.

There's also VAC ( https://en.wikipedia.org/wiki/Vergence-accommodation_conflic... ) as an issue depending on the UI in use.

I want VR to happen as much as anyone, but the Vision Pro is an entertainment-light device for media consumption with a nod for people who want to check their laptop (and I'm sure, eventually, their phone or tablet) while watching faux-bigscreen movies.
With ESPHome now supported on Picos (and other RP2040-based boards) this is an exciting time to be a home automation geek.
Because others use automatic ways to retrieve the data and derive value from it without paying anything
Exactly. If you want to do anything without going through Apple's benediction, you're shit out of luck. It's one more episode in the war on general computing, except somehow it's okay when Apple restricts what you can do with your three thousand five hundred dollar ski goggles.
Maybe you're just unlucky. I usually find an answer, or at least something that points me in the right direction.

The "me too" problem was prevalent with forums too.
> In such environments programmers are offered a mechanism that has many downsides of parallel / concurrent programming (eg. unpredictable order of execution) without the benefits of parallel / concurrent programming (ie. nothing actually happens at the same time, or only sleep is possible at the same time etc.)

From the developer's perspective it's a massive upside to not have to manage low-level details and just define how the event loop will call their code.

Any modern web browser has plenty of parallel execution behind the scenes, but the developer (and user) will just see concurrency which is much simpler to reason about. The order of execution doesn't matter if the things being executed aren't dependent. What matters more is that there's only one thread to think about. If they are dependent they shouldn't have been parallelized in the first place, so they're not.
Theranos fraudster Elizabeth Holmes says she cannot afford to pay back victims
I agree that the price doesn't matter as much as the experience; the Hololens 2 is just as expensive but generally people wouldn't commit to the limited field of view and lack of compelling use cases. Aside from media consumption and general computing prowess, I'm not sure if Apple made a complete case for it, but we'll see what software is ready to ship with it when it launches. Possibly people will be excited enough to develop for it that Apple can reach a critical mass of interesting "things to do" on the platform.

I think this makes it interesting!
