My Walmart even let's you void some items yourself, as well as not caring at all about the scale.

I'd consider it a plus honestly at this point, self checkout has no line, and short of a cart full of groceries, it's likely faster.
It still has to get to/from space at some point on each end.
It’s definitely not dead. Some great demos have been released in recent years in JavaScript / WebGL, e.g. using visual tools like cables.

He's not living in a stereotypical apartment -- it has a large living space (in which he's able to host fairly large parties for the upper crust), a well-appointed kitchen, a separate floor for bedrooms, and a third floor that's never seen on the show.
At ICA in Sweden they solved this by doing random checks of the cart at checkout to verify

The Celsius scale is an "interval scale" while the Kelvin scale is a "ratio scale". One cannot take ratios of Celsius temperature values as ratios are not even defined for that. It’s possible for differences of temperatures on the Celsius scale, though.

There are definitely machines that suck and treat any little sensitivity as a potential theft. Blame goes to the machine makers and the decisions makers of the store. Generally self checkout definitely has its 'lane' with the 'less then 10' items shopping trip.
You can also just start talking in chat, even in group channels; doesn’t have to be DMs. And the you’ll have a log of your good ideas. And likely someone random will jump into your discussion.
Not all titles are available in 4K unfortunately. We used to have the 4K plan, and in my experience very few of the things we watched had it.
Self-checkout literally always works for me. Items that require an ID, requires an associate to confirm, but they're always there to help me. The worst thing about self check out is when there's not enough machines!

If you don't know how to spend it, spend it on expensive office items that can easily be sold on secondary markets - ideally those that don't need ebay etc.

A question for people researching LLMs and their capabilities:

Is there any reason to believe that the interaction of multiple agents (using the same model) will yield some emergent property that is beyond the capabilities of the agent model?

I'm not working with LLMs, but my intuition is that whatever these multi agent setups come up with could also be achieved by a single agent just talking to itself, as they all are "just guessing" what the most probable next token is.
My beef with self-checkout tills is that I don't use carrier bags, preferring to put my goods in my backpack. The self-checkout tills won't accept a backpack in the packing area; too heavy, I suppose.
And then there is my local home depot which seems to have a 1:1 ratio of employees to shoppers much of the time. And they're all so chipper and helpful. Almost too much so.
See the other replies for options.

Nobody wants a package manager for C in the C world. We want a package manager for whatever language we write our code in. A lot of C code is not a single C ecosystem, but coexists with other languages, even where it is all C we often have various code generation tools that look a lot like different languages that just happen to generate C, and sometimes we want to package the into for those tools not the C output.
Take your point to its extreme conclusion and you will reinvent Gemini.

That’s why I like Gemini so much (and developed my own command line browsers which display the content of a web page in the terminal without caring about CSS/colors/etc)
Self-checkout is mostly fine for a few barcoded items that don't require age approval (like alcohol). Even awkwardly shaped items at places like Home Depot work pretty well these days given hand scanners. But having half a cartload of groceries including a bunch of produce? I'd much rather have a cashier. Aside from the slow process of looking things up, self-checkout areas just aren't setup for checking out and bagging a big pile of goods.
I usually see high fences before I see the court, so it makes sense to me.
Deshittifying the IoT Starts with Me
Every time I do self checkout at Krogers and it asks me if I put down a bag, selecting "yes" always triggers an employee verification (as does selecting "no"). I don't get the point in prompting the user if no matter what the user selects it always triggers an employee verification.

Another annoyance is you have to remember to scan your alcohol last or else it will block the checkout until your ID has been checked, Walmart has figured this out and only checks your ID when you hit "checkout".
That story was widespread, and ultimately false, with the correction never reported as loudly.

SpaceX had always had the cells over Crimea disabled, Ukraine was not aware. Ukraine asked for the service to be enabled there for their drone, this went against SpaceX's policies and the US's policies, so they refused.

At that point, the US had not given Ukraine any guided weaponry that had enough range to hit Crimea, Ukraine was looking to use Starlink as a guidance system, this would've created all sorts of issues and since Ukraine had asked for the cell to be unblocked IIRC a day beforehand, there wasn't enough time to even consider working through the various risks it'd expose SpaceX to.
I find it interesting that everyone immediately assumed I was talking only about guns. The advantage includes the right to peaceably assemble and speak freely, and petition the government for a redress of grievances. But to think that will always work out without a too-significant crackdown by the government hampering the process, is totally utterly ridiculous.

It continues to fascinate me that people have already forgotten, or never heard, the stories of the foundations of the country. We asked the existing government multiple times to allow us to handle ourselves, and give us more autonomy. They outright said no. And what was one of their first actions in response? Go take the plebs' guns. Now, if controlling the arms, ordnance, and munitions isn't important, why is that?

And no, our government being a republic rather than a monarchy does not make this time any different than the last. It should be evident by now that all it does is slow down the inevitable, and prevent us from pointing the finger at any one specific person. Which is to say, it'll be even harder this time. And that is not an excuse to give us less advantages. It is a reason we need more, or our future generations are more doomed than we already have allowed ourselves to be.
What do you mean by "far-right" tendencies?
Taiwan would love to know the answer to that as well!
Might work with clear bags, but otherwise you put it way at the bottom underneath a bunch of small items. No checker wants to make you dump out a shopping bag full of yogurts.
No, that's very practical advice! You're right - best to get stuck in and solve these problems as I go
Agreed. In fact, the complaints the article starts off with seem to screem "I'm an idiot that can't follow simple directions".

All the self checkout systems I've used are near identical. You move unscanned items past a scanner and onto a scale in the bagging area. Nothing confusing about that
I had the same question and made a browser extension that addresses many of the complaints in this thread (poorly-positioned elements, sizing, dark mode): https://github.com/dan-lovelace/hacker-news-pro. It lets you completely rebuild the layout however you'd like and has some pre-made themes that do a decent job without writing one from scratch.

You lost me on the title of this post "If X I'd be rich", without reading a single word immediately my reaction is "that's an incredibly naive or just plain stupid viewpoint". After reading the blog post my initial reaction was correct.

Heck, I'd probably be a billionaire if only someone had invested in my first startup /s

See how silly that sounds? Also as others have pointed out Amazon is not the only advertiser on the planet, you just aren't able to advertise on Amazon. I'm not saying being able to run ads on Amazon wouldn't be profitable but without comparing or even trying other methods I find the whole "but only if..." tone of the post even more ridiculous.

You’ll probably want to translate your great idea to a digital diagram at some point for the design doc or documentation. Might as well start there, then you have less work to do later.
it's not an exaggeration, there were also stores near where I live in <major city> that tried to do something similar with scanning apps and then abandoned it due to theft and added the standard self-checkout stations you see everywhere now.
Well, that’s basically what we do on Gemini ;-)

Nginx and php-fpm (and the started php pool processes) together provides simultaneous parallelism and concurrency because each web client can do (edit: multiple) independent things at the same time.
> capitalism fosters innovation

This is incoherent non-sense, it's also ahistorical. In 50 years the USSR went from poor farmers to defeating the Nazis and inventing space travel. In today's capitalist society it's obvious to anyone that the system holds back orders of magnitude more innovation than it fosters.

It's also irrelevant. Your opinions on any world countries that existed 1900-2100 AD won't translate well to a projected futuristic 3000 AD+ type society.
> 1. Payment processors know everything because they process the payment

They know all the information you given, but in practice they can't even verify "name on the card" that you entered in most of countries. In some countries they can check your billing address ZIP code, but that's all about it.

And there absolutely no way for them to find out if you are unique user with one card or you just have 10 cards for the same credit account or created 10 supplimentary cards for all your family and the dog.
Here in Denmark, I use the “Scan & Go” feature whenever available. I use my own bag, scan items using my phone before dropping them into the bag, and use Apple Pay to finalise the whole transaction. A QR code is displayed on my phone allowing me to open the gate at the self-checkout line.

I can be in and out of the shop within a minute or 2-3, never needing to talk to a human.

The only disadvantage is that I can’t get my bottle deposits paid out using the app; I have to go to the till for that.
Not a new issue:

Show HN: AI-powered Chrome extension for Google Meet
Hello Hacker News! We've noticed that many people use Loom to record their meetings in the background, which may prompt some privacy concerns.

As a solution, we've built a simple extension that notifies users about the ongoing recording of meetings (without the need for inviting a virtual participant). Additionally, this tool allows for the generation of customizable meeting notes.

Let me know what you think about it!
Naval patrols.
My big problem with it is lack of insights. When you scale dev you really need detailed stats on CI performance and bottlenecks
Same here in Estonia. Virtually all chains support one of two solutions. First one is scanning items at the checkout area - this does not have any random checks by staff. The second one is with the handheld scanner, where you might get occasional checks when trying to pay, but these checks happen rarely if you pass several checks without any issues.

Best thing since sliced bread IMHO, very quick and easy. Most stores have reduced cashier stands from eg. 10 to ~2.

> Those terms assume there is some predefined behaviour rules which are being circumvented, but those rules don't exist.

Those rules do exist though. I agree that if it was a true exploit, it would be breaking the ruleset that the ChatGPT programmers have in place (eg allowing critical statements of certain political footballs and preventing others). The ruleset can easily be discovered to some extent, by trying to get it to state unpopular opinions.
Sigh, That's not a study that's an article reviewing other cherry picked articles.
It doesn't really mean all that much tbh.

Long covid is still not properly defined and is more of a blanket term of feeling like shit after virus infection

List includes https://www.nhs.uk/conditions/covid-19/long-term-effects-of-...

* extreme tiredness (fatigue)
* feeling short of breath
* loss of smell
* muscle aches

OR.

* problems with your memory and concentration ("brain fog")
* chest pain or tightness
* difficulty sleeping (insomnia)
* heart palpitations
* dizziness
* pins and needles
* joint pain
* depression and anxiety
* tinnitus, earaches
* feeling sick, diarrhoea, stomach aches, loss of appetite
* a high temperature, cough, headaches, sore throat, changes to sense of smell or taste
* rashes

Many of these symptoms are simply post viral fatigue
https://www.medicalnewstoday.com/articles/326619#what-is-it.
Post-viral syndrome may cause additional symptoms, such as:

* confusion
* trouble concentrating
* headaches
* aches and pains in the muscles
* stiff joints
* a sore throat
* swollen lymph nodes
Which was considered perfectly normal before the big C.

Maybe long covid is a thing, but it really needs proper definition then.

How sick I am of the Covid nutters. If you want research money for something it seems to be just enough to slap some covid label or other and a cheque will be written no questions asked.

WeChat is backed by the CCP, aka the government with a military and de facto legal control over Apples factories. If they don't comply with WeChats requests, the CCP can ban Apple from doing business in China, with force if they have to. Hence, Apple complies.

That's where the precedent comes from - WeChat (as well as basically all major Chinese companies) carry state backing to force their way. Musk has afaict no backing from any government, least of all the DoD (who hate his guts for the shit he's pulled with Starlink in Ukraine).
I started making my own tracker music at 15. Grab yourself a tracker and a bunch of samples and give it a go. For me it was FastTracker II and ripping samples from the .mod and .s3m and .xm files I could find.

Yours will probably be Milktracker, Modplug Tracker, Schism Tracker, and a bunch of royalty-free sample packs online.

Yeah your first module will suck. It's OK. They all do. Soon you'll be discovering open fifths. Then inversions. Then suspended chords. Then modes. Then panning tricks, portamentoes, playing with the all the effects and envelopes and all the cute tricks invented in trackers since I last used one.

I'm "Broam" on modarchive.org
I also have the problem in bash, as the history is not written until the shell exits (having it write history command-for-command results in interleaving history with commands from other sessions, which doesn't work well for me).

But in bash, backgrounding works, so it's not an issue.
Joining in the mix here. I literally take such great pains to avoid having to use anything OTHER than self-checkout. They are a god-send to mankind.
It would actually be completely fair to say that X now costs $1 per month to use. You'd have to drop the ads as well, which given their fall out with larger advertisers again would make sense. In some weird sense it would fit with my overall view of Musk, if the advertisers don't like what he's doing, he'll block their access to his platform.

Journalists, consultants and influencers could just expense the cost and get a tax deduction or have their employer pay. Given the value most people claim to get from X/Twitter I don't see why $12 - $20 isn't a reasonable cost.

I'm also not sure if a dollar per month would be enough to keep bots at bay, it's also a little unreasonable to simply outsource your vetting of users to the credit card companies and banks in this manor and I doubt that neither VISA nor MasterCard finds the idea amusing.
I'm going to disagree and say that self-checkout has been good, and I only see the systems improving at stores I frequent and more stores are adding it every day. I'd call that a success.
Within a node it would improve compression, so in theory your overall system would benefit. This diminishes as you increase the number of nodes. TBH if you have a very small number of nodes I think just having a synchronized counter is fine. You can make extremely fast counters if you allow for gaps.
Sounds like Musk got inflationpilled.
Hmm not a fan of cryptobros. But if this can help SimulaVR move forward, ok.. It's pretty clear they are on the right track as Apple is now following in their footsteps.

PS: I was a big fan of crypto back when it started due to the "sticking it to the system" possibilities. After all it came up out of the ashes of the financial disaster of 2007 which exposed the banking establishment as being corrupted to the core.

However it very quickly pivoted to "work within the system to get rich FAST!1111!" and I view ETH as part of that, this is where my sentiment comes from. Especially since we're heading for a new banking crisis and everything is back the way it was before 2007.

If someone considers this is hot take, my apologies, it's my opinion alone.
Yeah, I have the same problem, I usually just end up putting everything into my backpack after I've paid. Slows things down.
I'm pretty sure the various managers can play with that experience. I've had Walmart self-checkout complain if I moved too quickly or removed items from the scale after scanning them. They've also complained when I had a second person handing me items from the cart or if I was moving too quickly.
That's a ridiculous thing to say. They'll either let you go or give you a raise and promotion to retain you according to whichever serves their interests at a given time. It cost them time and money to hire you so it's not efficient for them to let you go casually. Layoffs happen in bulk because the steady state tendency is to keep people around longer than needed, until the company reaches a certain threshold of oversized relative to need or viability.

It's just business on both sides. You'd also leave if it served your interests. Nor were they your family, committing to keep you forever. There's no reason to frame the relationship as adversarial or inherently toxic, even if it is impersonal and transactional. A transaction can benefit both parties.

Only for the boomers who still struggle with touchscreens and digital instructions and want a poor person doing the checkout for them. I have literally never seen someone younger than 50 have an issue with self checkout.

You're missing the fact that Starlink doesn't take your traffic to the destination. It takes to a nearby downlink station. Then it goes on those same optic cables to the destination.
Fiberoptic cables aren't perfectly straight either, and light in space is about 30% faster than light in fiber. Considering the link up&down to space adds about 1100km, the break-even point is at around cross-continental distances.

The speed difference is big enough that high-frequency traders have been using microwave relay networks for years now. Turns out that a relay chain of point-to-point radio links (which also operate at light-in-space speeds) has enough of an advantage over regular fiber links to be worth the hassle.

I'm sure there's some way I could get it off the drive of the broken phone which I still have somewhere, but quite honestly, if an organization is going to make it hard to interact with them, I won't do it unless I have to (banks, hospitals lol). I still like Firefox but I'm not gonna make extensions if they're gonna make my life harder.
Because the "beam" in a fiber is tiny and can be controlled, while the beam between two sats is actually very large and runs in free space. Most of the transmitted energy will always overshoot the receiver, resulting in significant crosstalk issues once multiple sats are in sight of each other. You cannot have two beams running the same path on the same frequency, not in space. But new fiber can be laid down infinitely along identical paths without any degradation.
Ask HN: Can you suggest advanced books on integral calculation?

Normal people don't even know what to do with the code. If a project is source open or not is completely irrelevant to them. To them usually it's way more relevant that open source software can be picked up and further developed by any other software developer and that it's free.
