Self-checkout software is more or less a layer on top of (antique) PoS software (usually provided by IBM or whoever they sold it to since).

What you see here is an artefact of that, as that's exactly how most cashier-operated PoS systems behave.

Buying Organic to Get Authenticity, Safer and More Nutritious Food? Think Again
Also: the dependency solver in pip is not correct. Instead of analyzing dependencies collectively it starts downloading one dependency, then adds its dependency graph and so forth. It works most of the time but it can be stuck in a place where a solution is possible but it can't find it.

Still, pip handles simple projects well, but when you add enough dependencies that have a complicated relationship it will break down in a maddening way.

Poetry's solver is much better than pip, I don't think I've ever seen it fail to solve an satisfiable problem but I don't believe it is perfect or efficient.

The correct way to solve it is download the dependencies of the dependencies before you build them. You can download the dependencies of a wheel from pypi without downloading the whole file because wheels are ZIP files and ZIP files allow random access.

The ideal product does a search process over the metadata before it downloads the packages for real as a

https://en.wikipedia.org/wiki/Satisfiability_modulo_theories

problem. It's possible to do for wheels but for eggs it is not straightforward because you have to run the setup.py to get the dependencies. eggs are not so common these days so a disciplined operation could have a process to build their own wheels from the eggs and put them in a repository.

The ideal system also has a facility to substitute one package for another, for instance "intel-numpy" for "numpy".

Self-checkouts and checkouts in general have gotten slow because they're increasingly dominated by elderly customers. At least that's my experience. Over the last 5 years, I've noticed way fewer young people shopping in person. I think a lot of those under 50 have switched to services like Instacart and Amazon Fresh. And I can't say I blame them. The checkout process has become excruciating. I love and respect my elders, but for some reason they collectively fail to check out in an appropriate amount of time without error.
An unsubstantive one-liner doesn't meet the HN bar for critique
It's difficult to agree or disagree with this comment, because it's so vague. For example, "on the whole they don't do well at delivering software, and have a reputation as terrible places to do software work." Are we supposed to just accept this claim without question? I have no idea which companies you're talking about. And I'm not sure that Apple and Amazon for example don't have reputations as terrible places to do software work, but again I'm not entirely clear on what you mean by that.

Moreover, "good software" is also highly subjective and subject to dispute. I feel that the software coming from Apple and Google has gone downhill in the past decade. Are we to explain that by hiring?

The financial numbers are indisputable for Apple, Microsoft, Google, Amazon, and Facebook. (Not sure the term FAANG even makes sense anymore.) But something like "reputation" is another matter entirely.
My sister’s home in Anneslie MD has one of these in their basement. Pretty interesting piece of history!
Is it common that manned checkouts will have the cashier bag your stuff for you? I haven't experienced that in most central London stores.

Chains are inferior to D-locks, so a stand that doesn't work with the latter is a failure. Also as mentioned, these kinds can end up damaging the wheel if any torque is applied to the bike and it tips over (wind, other bikes leaning on it).

And I think the manufacturer really did intend these to be mounted to walls rather than the floor. The second tweet shows that it's actually hinged, presumably to allow the bike to come in at a non-right angle to the wall, which wouldn't make any sense at all if it were on the ground.

The rise and fall of Cathie Wood, controversial Wall Street investor
I'm gonna be Cartesian tonight and say that some truths are self-evident and one of them is that this article is a joke. As I said in the thread below, I've used this machine and many others and if you've done similiar it should be self-evident that this fawning click-bait article was written by some child.
To be fair, the self checkout are mostly replacing the cashiers in supermarkets that are lowly paid for a very though job, who probably don't know you and who would probably be fired if they "lost" one second saying something nice to you, not the friendly fruit producer from your local market.
Yes, really.

I've done (and do) substantial work in SQL as well. Currently almost the entirety of our business logic is implemented in it, both to avoid the delay of round-tripping large data sets and for security reasons.

To be clear, this isn't CRUD code. There's a lot of custom ML bits, vector algebra, etc., running in Aurora Postgres where C and Python are off limits. Without PL/pgSQL many of the functions would be impractical.

The optimizer isn't the main source of headaches, but it doesn't help. I've caught it doing things it shouldn't be doing -- Aurora's fault, not Postgres' -- and having so much complexity locked away behind a magical "feature" is endlessly frustrating. Not everything is visible in a query plan.
I'm intrigued. Can you give an example of how mainstream superdeterminism would allow us to radically change society and change how we view norms? From the perspective of current society, superdeterminism and the resulting alternate society?

This system doesn’t support interactive transactions does it? In that the whole read / write set needs to be known up front before a transaction can start being processed? I know that systems like FoundationDB and Calvin/Fauna work similarly and get incredible performance because sequencing is so much easier / lock free. I think those two systems couldn’t be adapted for interactive transactions really (without client side retries) but maybe warp could be which is cool!

> there's something deeply wrong when you get a feeling like that

Everyone knows that feeling depressed is deeply wrong.

Medications that can cause depression are often prescribed for serious illnesses, like debilitating mental illness. They don't always cause depression, and the small risk of temporary, treatable depression is determined by the doctor and patient to exceed the risk of the condition that's being treated.

How to get into a UI/UX niche with no experience
The problem with this option is that it requires a loyalty card, sharing personal information and agreeing to a "privacy" policy (from experience, if a "privacy policy" is mentioned, your privacy is about to be violated).

If they could make this system work with anonymous accounts (walk up, swipe credit card and pick up scanner, put back scanner when done and the previously-authorized credit card is charged the appropriate amount) it would be lovely.
As a former professional Smalltalk developer, I would caution against the experience of greybeards who wax lyrical about the incredible power of Lisp and Smalltalk, because even in their heyday that power was largely illusory.

Firstly, anybody who encountered these environments early in their career will always be misty eyed about them.

Secondly, ask them how big the team was they were working in and what the mechanism was they were using to deploy their programs. Smalltalk in particular is particularly difficult to package up into a deployable program that somebody else can run, and collaborating on development is fraught with code sharing issues you just don't get with less exciting environments like .NET or Python or Javascript/Node.

In a modern context, Smalltalk and Lisp make little to no sense, especially when you have available a rich system of code being shared in more prosaic environments. It's a modern miracle that you can build what you need without re-inventing the wheel. There is no better time to be a programmer than now.

Lisp and Smalltalk may well be great for reinventing wheels, for writing un-readable self modifying code and as a challenging intellectual exercise, but all your productivity just went out the window.

> according to the Linux Raid Wiki¹, Hardware RAID 1 is better than Software RAID 1.

Don't take that too much into consideration - the article was last updated in 2007 ( https://raid.wiki.kernel.org/index.php?title=Overview&action... ) so it lacks some details (the same can be said as well for many ZFS-related infos that you might find) => nowadays doublechecking articles related to raid and ZFS is a must.

In my case I bought some HBA (Host Bus Adapter) cards (e.g. LSI SAS 9211-8i), set their BIOS to not do anything special with the HDDs connected to it (to be able to use them as well with other controllers) and used mdadm (earlier) or ZFS (now) to create my RAIDs => it works well, i get max throughput of ~200MiB per disk, I have all fancy features of ZFS without the problem of proprietary stuff related to the controller card :)
I also rely on this feature extensively but it's functionality has been broken for 3 years now, with no sort of interest in fixing it in sight.

Oh man I have been smoked by data-dependency like this so many times. I've gotten a lot better over the years at "seeing" data dependencies in godbolt or whatever, but it still slips through by my code and that of my colleagues way more often than I'd like.

Plain old atmospheric CO2. We've upped the amount in our atmosphere to well over 400ppm. Drowsiness becomes noticeable at over 1000ppm but with the now higher atmospheric CO2 and the fact that many of us now live and work indoors where poor ventilation can increase CO2 levels you have a recipe for subtle cognitive problems similar to what lead caused.
I'm curious if anyone has more details on the Skywater 130nm process. A cursory websearch indicated that it's an open-source CMOS process. Is it new or has it been around for a while? Lots of suppliers or just a single one?

I've been thinking that with supply chains breaking down, there's possibly a market opportunity for semiconductors to move back to older, cheaper process nodes that are easier to build a fab for, ensure there's a robust supply, and recover some of the recent performance improvements through less-bloated software. Chips were "good enough" back around 2001, when the 130nm process was introduced. In a world where you can't count on robust transportation & commerce and global (or even national) markets may fragment, it may make sense to be able to assure chip supply locally, even at the expense of absolute performance (which is less important when you can't be sure there's a single winner-take-all market). Would this program be a step toward that world?
This mirrors my personal experience. To make a treatment decision, against the advice of my local doctors, that was key to survival I relied on US research.

To compare costs: For an extremely rare cancer, total cost of treatment was 100k EUR in Germany, whereas US patients report case costs of >2m USD.

Part of these savings stem from the public healthcare system not providing adequate treatment, while strictly necessary for a reasonable chance of survival in this case. What happens in Germany then is the amazing doctors do stuff anyway (if you can convince them), bill whatever they can, and write off the remainder. Profits from privately insured patients make up for this shortfall here.

Public healthcare being adequate is somewhat of a myth, for Germany at least.
I bought an HTC vive pro + wireless + index Ctrl.

I did that to play around as I was playing with 3d programming and I'm a nerd.

And while friends and family know that and a few tried it out for a little bit and liked it, no one cares.

Which is fine but it is a gimmick.

I was hoping it would get more traction with real life training like how to use a lathe but nothing really came out or is in some internal companies.
Uniqlo does this - they have RFID tags embedded in their products so you can just dump all of it in a special basket at checkout and it autodetects everything. I suspect they also work for anti-theft as there are no separate, bulky anti-theft tags to remove.
In Seattle, the City Council has decided that the purpose of stores is to provide free stuff to shoplifters.
>In some of those cases, I've just left my groceries there at the machine and walked out the store. I tell myself "That'll show 'em, they'll have to put all that stuff back on the shelf!" But it obviously doesn't show them anything: they never fix the broken parts of the self-checkout and I end up having to return to that supermarket (or another) for the reason that brought me into the store in the first place.

This seems... like a pretty lame take.

I bet in most cases the employees will never know why someone just left their stuff there. Some of it could be perishable so it'll need to be tossed rather than re-stocked onto the shelves.

And not only that, I doubt the people responsible for those machines at whatever corporate level are really checking metrics on why someone starts a checkout and then randomly stops. That's just too many steps removed.

However, there should definitely be a better way. I just don't think this is it.
China vs. Elon Musk: Scientists Develop Plan to Destroy Starlink Satellites
You actually have to be careful. There's disk sizes where the manufacturer will do say 8TB CMR and essentially the same drive with different firmware as a 10TB SMR. They'll also have a 10TB CMR model. You have to pay close attention to the model numbers. It's even more of a crapshoot if you shuck drives. You have to carefully research what externals are known to have CMRs.

SMRs are a fucking blight.
Never heard of smoothwan but I've been running PiHole on LXC on OpenWRT for years. It was never difficult to set it up, I just created a Debian (or Devuan, can't remember now) container and ran the PiHole install on it.
It's pretty ridiculous, at least here in the SF Bay that the self checkout lanes have these features that are meant to deter abuse of the system, when in fact the entire store runs on the honor system and has a policy to not stop anyone who simply walks in, grabs a bunch of stuff and yells "thank you" as they casually stroll out without paying.
Specialization for sure is part of the equation, but I dont think it is the full picture. Also to get to a dependency problem one does not have to claim a vast conspiracy, often created as unintended consequence of well meaning government programs, or policy shifts that create incentives for corporations to act in a manner that the result is a dependency instead of self reliance.

In the context here specialization means people are not sustenance farming working 16 hours a day creating 100% of their food themselves, however the other extreme of this is total dependence of your food from outside of your region, and the ability to prep, cook, etc you food to others.

There is a balance there, where by a person may not grow all of their food, but has a garden (even in indoor garden) to grow some things... Or buys from local farms, and learns how to cook their own meals instead of total dependence on prepared meals either from the store (i.e tv dinners etc) or from restaurants / fast food...

I know a lot of people where more than 80% of their food intake is cooked prepared for them, and the 20% that is "from scratch" cooking is like bacon and eggs level cooking...

That is with out getting into direct dependency on government...
Huh?

I only know one person who used bis VR set extensively like for 2-3 month and then falled back to play egoshooters.

If anything, PiHole might make it go faster because some requests don't go to out in the world, wouldn't it?
Presumably likelihood of prosecution depends on the actual value of the forgotten item, and since these systems are typically coupled to a loyalty card, they can also check history. They'll be much more lenient on a regular customer forgetting a 10$ item once than a brand new one forgetting a 200$ item.
Having different protocols for inbuilts and furnishings does not seem like a recipe for success.

(And yes, I know about 12VDC lights; I have a studio full of them, with DMX controls. They're not consumer-friendly.)
Its like how health is correlated with height.

Its true, up to a point.

you just have to ignore that at the extremes it's probably negatively correlated, and there's a significant non-zero possibility that at least in the short term, that possibility of negative correlation applies to the area VR is interested in as well.
Or perhaps more fairly: the self-checkouts fail to serve the needs of the elderly.
There’s vouchers, as mentioned.
