A good friend of mine sold product on Amazon back nearly ten years ago. I got to have a pretty good look into the operation as he sought my advice on both business and technology issues.

The best way I can describe what being a third party seller on Amazon is like is something like this: If you are interested in ending-up in the hospital with a massive heart attack, become a third party seller on Amazon.

This is my opinion, of course, your mileage may vary. That said, the things I've seen defy description. Things like your entire product line suspended overnight without cause, recourse or a clear and immediately actionable path to recovery. Or how about your entire account being suspended and the Seller Support people you talk to are useless?

And how about this one: How about people who never bought your product leaving negative one star reviews. Even better: People leaving reviews before they receive the product they purchased, then they cancel the order and it never goes out. I mean, think about it, as an example, say you buy a weight loss product. How can Amazon's software allow anyone, even an actual buyer, to leave a product review before they receive it? How can they allow it a week after they get it?

Here's a nice one: You manufacture your own product (not a Chinese one-in-a-thousand-copies private label product). In other words, you are the sole source and the sole retailer of the product. Nobody else makes it and nobody else is authorized to sell it. Amazon has no protections against some scammer claiming they sell your product. What happens is someone buys from one of these scammers and either get a box full of rocks, something totally different or a bad quality copy of your legitimate product. Whats worse is you are left to answer for what happened and your reputation, seller and product scores suffer due to the bad reviews.

Then there's the issue of no protection against competitors attacking your ads within Amazon. They have a pay-per-click system. You set a daily budget. Competitors will pay offshore click farms to click on the competition's ads while everyone in key markets are sleeping. By the time your potential customers wake up your ad budget is gone and you produce zero sales for your money.

I could go on. He left the platform and got really good at running his own online operation. His stress level is a thousand percent lower and, more importantly, he knows his business isn't going to be shutdown overnight by some all powerful online retail god who could absolutely ruin him. I mean, these people are supporting families. The way Amazon treats legitimate third party sellers is just terrible. And they make so much money because of them.

I deleted my own post to that effect, once I saw yours - so I also wonder about that.

However I’m not sure if YT has a separate DMCA process for copyright vs. trademark, or if they or people writing about this are just too lazy or uninformed to make the distinction.
It is the ideal for any business, but it definitely is not for the consumer or the economy, and this is why governments enact anti-trust legislation. The government is supposed to enforce against monopolies, but unfortunately in the US government this has been undermined. Matt Stoller has a great book and e-newsletter about monopolies past and present vs. government.

Disclaimer: i am a co-founder of Logical Clocks. There are loads of interesting technical challenges in this "Feature Store" space. Here are just a few we address in Hopsworks:

1. To replicate models (needed for regulatory reasons), you need to commit both data and code. If you have only a few models, fine just archive the training data. But, if you have lots of models (dev+prod) and lots of data - you can't use git-based approaches where you commit metadata and make immutable copies of data. It scales (your data!) badly. We are following the ACID datalake approach (Apache Hudi), where you store diffs of your data and can issue queries like "Give me training data for these features as it was on this date".

2. You want one feature pipeline to compute features (not one for training and a different one when serving features). Your feature store should scale to store TBs/PBs of cached features to generate train/test data, but should also return feature vectors in single ms latency for online apps to make predictions. What DB has those characteristics? We say none, and we adopt a dual-DB approach with one DB for low-latency and one for scale-out SQL. We use open-source NDB and Hive on our HopsFS filesystem - where all 2 DBs and the filesystem share the same unified, scale-out metadata layer (a "rm -rf feature_group" on the filesystem also automatically cleans up Hive and feature metadata)

3. You want to be able to catalog/search for features using free-text search and have good exploratory data analysis. The systems challenge here is how to allow search on your production DB with your features. Our solution is that we provide a CDC API to our Feature Store, and automatically sync extended metadata to Elastic with an eventually consistent replication protocol. So when you 'rm -rf ..' on your filesystem, even the extended metadata in Elastic is automatically cleaned up.

4. You need to support reuse of features in different training datasets. Otherwise, what's the point? We do that using Spark as a compute engine to join features from tables containing normalized features.

It's not, in my opinion.

Just something old - simple generated static site with sprinkle of {{currentJSFramework}}, a CDN, and some fancy marketing.
No, constexpr is not the same thing as template expansion. The decidability problem as I understand it is, "does the template expansion halt?" And since the template syntax in C++ is Turing complete, the answer is "you can't know." I'm just confused how this is significant or different from any other recursive macro expansion, it doesn't seem surprising to me.
Instead of complaining that you're not interested in all these different topics and people you don't want to know anything about, and then mentioning your own things as being superior to the things you're criticizing, but then refusing to say anything more about your own things when asked, and then complaining that Scott Kim didn't make a better Photoshop, but then complaining that "the real topic at hand isn't who made a better photoshop", and then being sarcastic some of the time, but also accidentally using words that mean the exact opposite of what you intend (which makes it hard to tell your sarcasm from your mistakes, just like Trump), it would have been a better idea for you to simply not participate in this discussion that you find so uninteresting and refuse to contribute to.
Most comments here focus on the question if "who deserves what?". This is a stupid question, as it becomes a tautology revolving around how people define the word "deserves". A more intelligent question is "what should we do to have the best outcome?". Is it better to have more companies around to provide goods, services and jobs, or more people around with stable housing and pocket money to purchase goods and services?
Absolution doesn't mean you ignore character traits, unless it's a simple society.

fun to watch this, like seeing the odd demo pop up on HN once in awhile and that code/techniques breakdown is incredible. Back in the day we rarely had that kind of insight into the mastery that went into a demo unless we really got into a discussion with the creator about the code.

another reminder of the 'art' of the demoscene and it's recent recognition as a piece of UN heritage in Finland which I thought was pretty cool

(HN discussion: https://news.ycombinator.com/item?id=22876961)
Students learn in a variety of ways. I imagine most of the HN audience excels at lecture based and book learning. To such an audience it makes sense that a single gifted lecturer could immeasurably benefit students through remote learning.

Many students will fail to thrive in such a scenario.

These students need different kinds of instruction. This is one thing that leads to home schooling - the government school does not provide the needed instruction methods, and the parents can either pay for private or do home schooling (or move).

> Taxation itself is a form of theft.

Propaganda.

> We never had an income tax in the United States before WW2.

There was an income tax during the American Civil War, but it was temporary. Then Congress passed an income tax in 1894, which was ruled unconstitutional in 1895. The 16th Amendment, which made it constitutional, was ratified in 1913. So your history is as shaky as your moral philosophy.
I don't have a problem with common core, I like that kids gets to see all the different ways to solve a problem. The problem I see is that schools are testing all the different methods instead of asking the students to use the method to solve the problem.
Selling the ballot was the concern, yes.

I don’t see any part of that process that would stop me if I told my employees “I’ll give you $100 if you show me your ballot then send it right away the day before the election”.
This.

We’re only two weeks into the term, and it’s been hell. With kids in primary school, unless you spend hours with them in the morning, they won’t be able to follow the set instructions without a million questions. We’re now getting up early and doing 2 hours of school before we both start work, and then doing another hour after I finish work. It’s stressful as fuck, but it just blows my mind when I think of parents who don’t have the luxury of WFH or who can’t understand some of the shit that schools are sending home.

We’ve talked to multiple parents, and ALL have cried along with the kids because they’re not coping. Some have even sent their kids back to school because it was unsustainable.
A common theme with Ponzi schemes is that the people at the beginning who created the scheme (or who invested in it earliest) benefit greatly by future people buying into the scheme.

Bitcoin started with its value essentially at nothing, and the early "investors" were able to create tons of it out of thin air.

Provided they held onto that Bitcoin, the "value" of the "currency" only increased as more and more people bought into the notion that it had value.

You can see how this would heavily incentivize early investors/miners/buyers to perpetuate the scheme.

Many early "investors" in Bitcoin made millions of dollars off of their gambles. I personally know quite a few of those people.

I hate to pull the wool away from your eyes, but that's not a deflationary, stable currency. That's a Ponzi scheme.

I moved abroad in 2018 to a non-english speaking country and just about everyone I met had Duolingo on their phone. You'd be surprised at how many would cough up for a Premium membership just to keep their streak from breaking and making the cute green owl cry.

That said, apparently their biggest market is actually people trying to learn English, which... checks out. In our modern times, english is the lingua franca. There's a bottomless pit of people who want or need to learn it.
That's not quite accurate, according to the article:

"“While school closure as a measure on its own is predicted to have a limited effectiveness in controlling Covid-19 transmission, when combined with intense social distancing it plays an important role in severing remaining contacts between households and thus ensuring transmission declines.”"
Looks like that gallery view is from last week? Also meet only, not hangouts, and not rolled out to everyone yet?

Either way it’ll be nice if they do that.

Other comment was a reply to the parent comment, I was stating that you still need gmail for hangouts and to have it turned on in your email settings, or you need the specific app.

I know less about meet - I think that’s some corporate google product I don’t have access to? Google’s strategy around messaging is impossible to understand so it’s possible I’m wrong about that.
I don't know what are you talking about. I am a regular person, who never spent time obsessing about photography, and all the pictures in the article on the left (I assume they took them with the phone) look very very good on my 40" 4k screen.
OP's point was about auto being littered in documentation and not in the code itself.

Having auto is a boon for certain design aspects. As system level programming language D offers everything in betterC mode. Of course it can offer more. But a small community can do only so much.
The former seems so much more likely to me. Probably because my German teacher had us watch ["The Lives of Others"](https://en.wikipedia.org/wiki/The_Lives_of_Others) and at this point it would be absolutely insane to imagine that the obsession with power that exists in the government would fail to find a way to read data that's literally stored on someone else's computer where you could never tell if it's been read. Seems like a no brainer, but without proof most people would rather just call it a grey area. Which is a fine enough narrative. Doesn't change much either way.
Calling out significant flaws is not pedantry. Defending arguments because they are "on your side", irrespective of merit, is destructive to the kind of reasoned discussion I value on this site (certainly it's not always available, but let's aim for more of it, yeah?). And I actually think that repeating obviously flawed arguments does the other side's work, turning away the undecided - especially on a site like this.

If the people have money, but the company can't sell to them, what good does that do for the company?

And if the people want to buy from the company, but the company goes bankrupt before the people are allowed to buy, then giving money to the people didn't help the people (at least not with respect to this problem).
How did you manage 3 at once from the beginning?

We're debating what to do come August. We have a 5 year old entering Kindergarten. We live in a good school district, but we don't want to be part of an experiment as they figure out how to do online learning. Online learning for 5 year olds sounds disastrous too. So we've thought of trying home schooling.

The thing is, that 5 year old comes with twin 2 year olds. And the 5 year old has a huge attitude when dealing with us, but not teachers. She is way more productive when it comes to learning stuff in pre-school than with us because she flat out ignores us at least half the time. Can't imagine how my wife would manage that along with twin toddlers running around destroying everything.

Days are already frustrating as hell for her. A majority of the day is spent with at least one of them crying over something. Trying to stack learning on top of it sounds like a recipe for bad times.

Edit: especially with social distancing. Any other time we could lean on grandparents or local families in similar situations. Right now we can't. Not everyone can use extended family in normal times, much less the current problems we're facing.
Static sites have evolved. Today, they can handle real-time requests, process payments, manage customer accounts, and a lot more. Some other benefits:

* Cheaper – Not making requests to the server on-demand
* Faster – Served from a global CDN close to your users
* Easier – No complicated deployments, better DX

How is this reshaping the web? In a way, we've come full circle. What's changing is how we get to a static site. JAMstack unlocks all the benefits of static sites with today's complex data requirements.
taking equity seems to pop up with every story on corporate bailouts.

the problem with taking equity is that it's not simply an income stream, it's a responsibility. you become a stakeholder and need to manage the asset lest it devalue in ways you don't like. it's messy and much more criticizable, something politicians and bureaucrats loathe.

fixed-income assets like loans are much simpler, and have the added benefit of naturally having higher liquidation preference (bondholders get paid before shareholders).

loans with performance penalties/incentives are cleaner to implement, but the problem there is lobbying that waters down penalties and magnifies incentives.

there's no simple solution, including taking equity. i'd love every loan to have a clause stipulating no executive stock incentives or share buy-backs for 7 years post-loan, but no one is lobbying for that.
I think a lot of people see “find me a number between 0.9999... and 1” as no more or less valid (plus, perhaps, no more or less pedantic and dickish) than “ok smarty pants, why don’t you just keep adding 9s until you reach 1, then we’ll talk.”
Maybe you shop for different things? I've seen things lately that were clearly cheaper at the local grocery store.

For things like PC components, I find them hit or miss. They might be the cheapest (or near it), but they might also be way more expensive than another legit retailer. These days, I always check, because they are so variable. A lot of that is probably that Amazon doesn't carry everything, and other sellers are a crapshoot.

I don't know where you live that their groceries are so much cheaper, but it isn't true here in Texas, where HEB (the dominant grocery chain) is hard to beat.
> if you put an engineering team on it that know how to write automated release procedures

I think surfacing the data is just the first step, often times data scientists need to run some data exploration, the process is generally iterative, and so they need to run several experiments, resume or restart some experiments, scale training with distributed learning using several machines, or run hyper-parameters tuning, which means handling failures, visualize and debug results, before deciding if they should deploy a model. Once a model is deployed the story does not end there, because models become stale and need to be retrained. There are other issues related to compliance that need to be handled as well, and many other problems related to governance, a/b testing, ...

The good news is that there are several open source initiatives to solve several of these problems, at Polyaxon [0] we are trying to solve some of the aspects related to the experimentation phase.

The fact that you're afraid of what legal might think of your response says volumes in and of itself.
Not all gross margin is the same
Lol. You obviously don’t have kids.
Rust was designed from the ground up and every feature is implemented and designed to work with its borrow checker. So it is able to provide a definitive guarantee that memory isn't free'd or used after it is free'd. The only exception is in "unsafe" code, where you can break the borrow checker. But this limits where you have to worry about potential bugs.

In D, the ""borrow checker"" is being tacked on as an after thought, in an attempt to copy Rust. This means that it doesn't play nice with existing features and makes it difficult if not impossible to guarantee that memory isn't leaked or used after it was free'd. For example with exceptions. The checker doesn't check for exceptions and if memory is free'd correctly if an exception is thrown. This isn't a problem in Rust because it doesn't have exceptions so it doesn't have to worry about checking them so it can maintain its strong guarantee.
