The result of a query isn't a set but a multiset/bag (sets that allow for multiple instances of the same element). One popular take on this is that this "breaks" the relational algebra which is certainly true if sets are the thing you want to base everything on like a lot of mathematics today. However multisets are in of themself a very interesting structure that has interesting properties which could be helpful in understanding distributed systems and general relativity.

Things like sum types and the option monad would be powerful additions to a RDBMS but I wish that people would not be so quick to dismiss anything because it is not a set. Sets can be extremely difficult to work with, just simple things like adding numbers together as described in peano-arithmetic is bunkers compared with multisets. Everyone knows how the 19 century dream of Hilbert of grounding mathematics in logic/set theory failed but somehow everyone keeps wanting to use them for everything. In my mind this is a shame and I don't think that removing them from the one place where they have a use in society at large is a good idea.
Thank you for calling my attention to this buying opportunity
> My biggest gripe with HelloFresh, et al is that I still need to do the prep, so they don't actually save me much time. It's nothing more than curated grocery delivery.

For me the biggest value add of Hello Fresh is the meal planning aspect. I don't have to spend time every week figuring out what I want to cook for 3-5 different meals, or track down the ingredients to make them, or add up calories to make sure they're health conscious.
SQL syntax is awful, but I do think many SQL programmers are aware of that.

One problem is that the SQL standard is very loosely followed by implementors, so the syntax and semantics of each implementation can be wildly different.

For instance, major implementations do not agree on if double quotes denote string literals or identifiers. "test" is either the literal string "test" or it is (e.g.) the value of the column called "test'.

I think this contributes in part to the difficulty of writing down a revised language to replace SQL.

Compare this to e.g. the C language, standardised at roughly the same time as SQL. In C implementations there is much stronger agreement about what the language looks like. I'm not sure why this is the case.
> most people don’t know what the good ones are nor how to find them.

I've spent a few years working in the information security space, and I'm quite certain that I wouldn't know which ones are "the good ones" and which ones aren't.
Speculating: this is why I expect the heavy computing will probably be offloaded to an iPhone via a new wireless protocol, possibly one that's specifically certified for it (an "iPhone AR^?") with beefier specs and a better battery, possibly larger in size to compensate.

Essentially allows the lenses to focus on only being a display at that point, which would let apple keep the footprint thin and partner with existing manufacturers e.g Luxottica, Marcolin, Safilo, etc.

^changed XR (extended reality) to AR per a reminder that the XR was an iPhone X variant not long ago
I think it's any career in which your bad decisions have the potential to harm millions of people, whether you're a bank executive or a rail freight executive hauling huge amounts of poisonous chemicals through residential neighborhoods.

The difference is that in banking specifically, the regulations seem to have some amount of teeth, so it's tantalizing to see executives receiving any material consequences at all.

Meanwhile I don't see the Norfolk Southern shareholders losing money or their executives losing their jobs. The incident is barely visible in Norfolk Southern stock prices.

$75M FDIC Coverage?
Rho.co claims to offer up to $75M FDIC coverage by splitting their customers deposits to a network of 400 banks. But, I know arrangements like these usually work until they don't. Is this a safe bet, given last week's events?
Was there ever a pressing need for that cover to exist in the first place? I don't think our society would be culturally impoverished if they had simply taken a picture of something else.
Show HN: We built a ChatGPT sidebar (annoyed by the popup)
Hey!HNs,so, I’ve been using ChatGPT a lot lately and experimented with a lot of their chrome extensions. But, I gotta admit, one thing that bugged me was those popups that would vanish as soon as I clicked away. That’s why my partner and I decided to build a sidebar instead. We’re pretty stoked about it and would love to hear your thoughts too! So, hit us up with all your feedback!
Yes, a much rarer thing.
Maybe you bury europe before it dies. There are sectors still successful:

I assume all of those are money market accounts like a brokerage sweep account as opposed to a regular bank savings account which, at my bank at least, are still paying 0.01%. Which may be a reasonable risk/reward tradeoff as 4% on, say, $100K isn't nothing.
If you read the whole thread it becomes obvious it sadly is not a joke.
Because they need to park Capital somewhere that gives a return, even if it's a small one.

It's not a bet that interest will stay low as much as I bet that they as a company will be around in 10 years to see the returns. It's a guaranteed profit if they make it to the finish line.
It would be nice if there was a consideration for the app being opensource for the free tier, and also integration with Github --- it would be way cool to be able to specify that a Python file on Github could be used as the source for a free app on your site.
My dad's bank switched to $COMPANY in the late 90s and to this day, when I run into people who work for them (which happens from time to time since they have offices in my city), I have to suppress my inclination to dislike them, since it was such a brutal two years for our family when dad was working 70+ hours unendingly.

This is a definition of bailout that seems to have been conveniently invented within the last 18 hours. Does it really not set your "I wonder if I'm rationalizing" alarm bells off when you find yourself writing out this weirdly very specifically narrow definition?

It's just simpler and more honest to recognize it was a bailout, and one that you support (as do I).

I think Matthew Klein put this pretty well on Twitter[0]:

> "We aren't using taxpayer money to do a bailout, we are just using the ESF and also having the Fed pretend that banks haven't lost money on their bond portfolios and we are going to charge depositors at banks that didn't fail to make depositors whole at banks that did"

I don't think anyone is going to crack VR in the short term. Watching this tour of Facebook's Reality Labs, https://www.youtube.com/watch?v=x6AOwDttBsc, it seems that they realize the challenges ahead. Looking at these challenges (resolution, brightness, eye tracking, form factor) is there an area where Apple is going to be a generation or more ahead? I think the world will be waiting another decade or so before VR gets anything like phone penetration in the market.
Audiophiles are people that need to understand that there's such a thing as diminishing returns.
Yes, good amplifiers and, more importantly, good loudspeakers and headphones can significantly improve your experience compared to listening to music in some cheap JBL boombox.
But once you're a step above the cheap stuff, additional expenses don't significantly improve your experience.

Indeed, home prices increasing at more than a modest rate is a bad thing for everyone in the long term.

Homes should be investments in the same way that a factory or warehouse is an investment. You buy instead of renting in order to fix the cost of doing business over time, not to speculate on potential future values.

Repair costs, local relative cost housing vs rent costs are both excellent points.

Regarding down payment, that is still something you could likely recoup, and putting it in an index fund isn't necessarily more stable (especially over a 12 month period).

Except for the very expensive markets like downtown NY or Silicon Valley, making 150k/year should be enough to finance a house (especially considering in those expensive markets rent is also very expensive). When you rent you're essentially paying someone else's mortgage with repairs priced in (mortgage is often less than renting).

Repair, relative local markets, and interest rates are all very relevant reasons that renting may be better.
I would add lifestyle and education to the list of failures as well.
Maybe it's unrelated, but I'm finishing college and in a couple of years we've gone from almost nobody using tablets to take notes to almost everyone having a pen-enabled device to take notes with. This is because we finally got cheap enough devices that were mildly pleasureable to write with and had mildly functional note taking suites.

I think the same is going to happen starting next year. Sure, AR is a bit behind VR in the public conscience, but the moment $200 AR goggles will prove to be marginally useful people will adopt them in an instant.
Your ideas seem really cool. I'm sad that you chose a name so close to another great startup that does vector databases and search. https://www.pinecone.io/

Right if you bank at a regional bank that isn’t connected to influential VC your deposits might still lose value.
I'm not sure if its because I grew up very poor but I always find people in my apartment block who use Hello Fresh and the like a bit 'snooty'. I can get an entire shop - breakfast, lunch and dinner *and* snacks for the entire week for the price of one of those boxes.

I barely have time to myself bit still manage to plan my meals and make my own dinner quickly.
why is HP on the list? its revenues are on par or slightly below competitors in the sector and if you add the enterprise revenues its more of a 1 to 1. Hp consumer revenue 60 billion, HP enterprise revenue 30 billion in comparison to dell 100 billion and lenovo 70 billion in annual revenue the two include enterprise revenues which isn't spun off like with HP. All three are at peak revenues. Aside from that cisco, ubiquiti, nvdia, amd, intel(ish),LAM, AMAT, micron are the best in their fields honestly its seems like EU companies are in shambles not US take a look at ericsson vs huawei idk if the US has any real competitors in telecommunication hardware cisco is more of a networking company nowadays.

> There's several things that seem to characterize many of these failures, the first is that when founders leave or die companies often seem to lose drive and direction, and second companies become too big and diversification seems to kill their R&D/innovation.

The latter is the downfall of most conglomerates. Kodak invented the digital camera and then failed to capitalize because they were afraid it would cannibalize their film division. Which was true -- it did -- but then the digital camera business went to someone else. Leadership needs to be able to make hard calls like that before it's too late.

Which founders tend to be better at than MBAs.

There are many things like this. Coffee people, for instance, who will straight faced insist to you that they can tell the difference between stirring the coffee grounds with a tiny metal "distribution tool" 5 times or 10 times, and who will post "recipes" for soaking ground up beans in hot water.

Just let people have their thing. They like it.
You're more-or-less describing nonwoven fabrics, which are used in a huge variety of applications. There's different fabrication methods, but they are typically not as strong as standard weaves since the patterning can't really be controlled.

Maybe I worded things poorly, but I understood your point: everyone would want to live in high-density housing if only they were better informed of how great it is.
My point is that that's flat out wrong. Many people know from experience what that life entails and want nothing to do with it. And yes, that includes the idealized fantasy version you present in other comments, even if that actually existed.

The "put" thing comes from my perception that you think the only reason someone could disagree with you on this is because they're misinformed. Maybe I've got you all wrong, but that mindset tends to eventually feel justified in forcing people to do things "for their own good".

I'll reply to your other comment here so we don't have to juggle multiple threads of conversation:

Anecdotally, my experience of cities vs. small towns has been the opposite of yours. Almost every apartment complex I've lived in has had one "nosy neighbor" that insists on gossiping about everyone's affairs and causing drama with everyone they can sink their social hooks into. But that's not really relevant--you prefer cities and I prefer small towns. That's fine. I'm perfectly happy for everyone to live in whichever of those suits them best, or some other arrangement. You're the one who wants to prescribe a one-size-fits-all lifestyle for everyone.

What is the difference and where can you see it ?
To be fair. If you had poorly shielded audio equipment (maybe because you bought directional copper and forgot to buy the necessary diamond infused audio grade shielding) then its entirely possible that different memcpy implementations might produce different frequencies of noise which would have a noticeable impact on the audio quality. Although, who am I kidding? These people also think Ethernet cables can be directional.
> While I find parents doing this extremely concerning I am personally really hesitant to change anything because I can't think of any way to change it that doesn't seriously hinder normal and not creepy parental uses of images/videos of their children

Ban the commercialization of videos and images containing kids. No more child actors, singers, models, etc. Remove the child labor law exceptions which have been given to these industries.
The traffic benefits of autonomous vehicles are dubious.

I don’t see how there’s be a significant benefit for people reliant on public transport. If people are stuck on public transport, it’s typically because of cost, and there’s no way a small passenger vehicle is going to beat out a bus or train on that metric.

This measurement is relative. Does it indicate decline in Europe or development in Asia?

It's unreasonable to expect a region with 1/16 of the world population to have 4/10 of the largest companies in the long term.

Also, is "company size" really that good a measure of economic success? Seems like it could have to do with the local conditions encouraging smaller economic entities.

You wouldn’t have both of:

Optional<T> a = null;
Optional<T> b = Optional.empty();

In other words, Optional would have to be a non-nullable type. Which of course means that, to have it be a reference type, Java would have to support non-nullable reference types. But if Java did support those, you wouldn’t really need Optional in the first place, because then the current nullable types would fulfill that purpose.
> They need to release it now and see how the word is using it and tweak it accordingly.

I don’t know. If you release something before it’s really ready you can shoot a whole category in the foot.

A 2005 iPhone would have been terrible. The 2007 iPhone was right on the edge of what was possible. A 2005 iPhone would have flopped because the tech would have held it back so bad.

Then there is the problem of why I’d want to use it.

There was a conversation on Dithering (I think) about this recently. The Apple Watch was still a watch and provided notifications. The iPhone was a phone and an iPod, plus the real internet. The iPad was a big iPhone. They all had predecessors so you sort of knew why you would want it. The value proposition was at least somewhat clear.

A VR/AR/MR headset is a totally new thing. For the vast number of people it doesn’t do what their X did but better. You have to convince/teach people why they need this and that’s a MUCH higher barrier than the iPhone/iPod/iPad/Apple Watch/Air Pods had.

The only thing that has shown some success is games. Apple is not good at games. They (as a company) just don’t ‘get it’. And if games was enough we’d see existing solutions be way more popular.

Plus the nausea issue is very real for a non-trivial portion of the population.

Maybe things have passed that magic threshold where, like the iPhone, little additions have added together enough to make Apple’s thing feel way more necessary that what existed before. But I’m skeptical.

They need Mario, VisiCalc, Word Perfect, Sonic, Page Maker, something to be their killer app.
HN is willing to call out any consensus other than its own as groupthink, policing its voices and members all the while. Willing to champion free speech, but not those who dare to speak freely.

I have some good friends who've gone the other way: they've asked that there be as close to no photos or videos of their child on any social media as possible. They don't post about him online, and they keep pictures of him in photo albums. When he was born, they asked all of us to please refrain from taking photos of him without their permission.

I completely support this and I intend to do something similar for my kids. Anonymity is one of the best gifts I can give them.
ChatGPT's Hallucinations Could Keep It from Succeeding
Nvidia doesn't need to acquire ARM to sell systems with unified memory. The Tegra boards are all mixed-address-space systems, and CUDA lets you manipulate memory over PCI. They see the writing on the wall, which is why they've been building systems for the past decade that reflect this philosophy.

If you think it's hard to imagine Nvidia hardware running on a developer desktop, wait until you hear about what happened when Macs tried entering the server market.
I think all Audiophiles recognise there are severely diminishing returns, but they pursue it because it's a hobby.

What they actually need to realise is that there's no magic in computers, and sometimes digital systems are literally identical as long as they aren't erroring. For example, copying over a network has integrity checks at several levels, so you can't receive a different version of the music.
Rivian, afaik, already had production delays, and are struggling to meet even Amazon's 100k order. What happens to new vans produced if the clause were to be lifted? Does Amazon get preferential treatment? Do they sell the new vans to the highest bidder? Amazon's follow-up orders?

Amazon owns almost 20% of the company so this is interesting. Rivian being more profitable doesn't necessarily make the trade-offs worthwhile for Amazon.
