HN stop supporting sites that block information with paywalls

The HN policy on paywalled articles in general is clear. 'dang has commented specifically on the NY Times as well. https://news.ycombinator.com/item?id=16003345

I don't know of any work around with the recent changes they did.

I haven't seen anyone discuss the technology...can this really be reliable? It mentions cameras above the shop floor and machine learning. What do the cameras look for? Are there special visual markets on the products to make this task more robust? If not, there surely must be caveats?

Are RFID tags not a more elegant solution? Or are they too expensive?

Earlier quoted context omitted.

>80% of the American population lived in what is called an urban area in the 2010 census [1]. While their definition of urban is looser than you might use, still >60% lived in 'cities'[2]. Unless the wealthier, more connected, more educated readership of Hacker News strongly bucks every trend suggested by their demographics, it's pretty safe to say we mostly live in urban areas.

How do you know HN is made up of only Americans?

OP said "most[ly]" not "only". Just wanted to point out that your comment shifts the goal posts.

this seem like really backward thinking, the future is to eliminate visiting shop, not simplifying checkout process

I don't want to step in shop at all, I want my grocery delivered to my door and the delivery guy/drone can on the way out throw my trash. I was doing this in China (it helps to live in city with concentration of 20 million people), they even offer the throwing trash service though didn't went further into that step

The demographic trends in the GP aren't unique to America. They're more or less the rule in most developed countries, and I think it's safe to say most HN users probably come from developed countries.

I know the standard reaction from a lot of HN folk will be to celebrate this progress: it's faster, more efficient, and no one likes to waste time waiting in line. Still, though, I think Amazon's automation of the retail experience is helping to create a society where there is even less real social interaction, and I think it's a factor (if even a small one currently) in the increasing tribalism in American society.…

Maybe, maybe not. Less cashiers can mean more floor staff. Even at a place like Target, I need help now and then and the few floor staff are running around like crazy. And they already have self-checkout scanners.

It's fine to ask for workarounds. It looks like they still support a limited number of articles for free. Others have already posted workarounds in this thread.

Techcrunch article with additional technical details: https://techcrunch.com/2018/01/21/inside-amazons-surveillanc... > ordinary RGB cameras, custom made with boards in the enclosure to do some basic grunt computer vision work, presumably things like motion detection, basic object identification, and so on. They’re augmented by separate depth-sensing cameras (using a time-of-flight technique, or so I understood from…

Imagine when Amazon sells this system to Palantir and police departments for use all over town.

And does what with it?

RFID tags have a lot of problems among them that unless you get every manufacturer on board for labeling all the products in your store you're going to have to spend a lot of time labeling products before shelving. It's also a continuous cost per item either from the manufacturer or from the in house labeling process where a static system like Amazon Go can track without adding a per item cost. It's also not good enough to be the only system in a store because it's easy to block the signal using a foil lined bag so the store will already need another system at least as good as RFID at tracking things coming off the shelves.

As for what they look for that's the secret sauce but there's a few things that are pretty clear from descriptions. They seem to be using mainly (only?) cameras for the identification. Luckily branding is pretty prominent so they have a pretty convenient thing for their item labeling to look for in the feeds. For cart shopping there's some simple things like tracking people with their faces from when they enter then adding items to their cart when they move an item outside a defined shelf region.

When I installed the app it mentions you can let others buy stuff from your account with a single phone on entry(kids, friend, etc). There is an animation that shows you tap your phone in, send your friend in, then re-tap yourself in. Didn't see this mentioned anywhere, and I thought it was kinda neat.

Kind of confirms what I'd always thought, that they'd associate a face/person with an account/shopping basket then track that through the rest of the store instead of doing any phone based tracking.
