Sure you can. You develop a system, learn how to find information, and make good predictions of future human behavior. You should learn the ins and outs of the product you're trading.
I wonder if selling, perhaps at a discount, to a relatively passive secondary buyer like Industry Ventures would have been an option?

> Labor is a major cost for retail

At least it used to be true that self checkout systems are not primarily sold with the promise of reducing labor costs, but primarily that they take up so much less space. If I remember correctly, six self checkouts take up as much floor space as one manual given the longer queues of the latter. That's why they first were sold in the cities where space is at a premium.

You still need some employees around the check out area anyway, and even if one employee can serve several you also suddently have many more of them. The manned check out was never the most labour intensive part of running a store anyway so it wasn't the best selling point anyway.

This walk-out concept has to compete with the various self scanning schemes that already exist, not with the manned check outs of old. It will be interesting to see if they can offer a cheaper and more reliable experience to shoppers.
The thing that stopped the spread of coronavirus in Hubei after ~50k infections is the lockdown. The lockdowns began January 22-23rd, affecting about 59m people. Nobody is leaving their homes except a few essential personnel, to include medical personnel and food delivery. That works in China but it probably won't fly in most liberal democracies. At the time, less than 2k people were confirmed infected. Exponential growth continued for two more weeks, until hitting its inflection point. That's with the lockdown.

Coronavirus has begun exponential growth in the rest of the world. The rest of the world already has more cases than China did when exponential growth inflected.

As of today, it's not showing any signs of inflection. On February 26th, Trump said we had 15 cases in the US, and would be close to zero within a few days. 11 days later, we have 607 cases, 22 deaths, and 8 recoveries. That's a growth rate of 40% per day, and holding steady.

The scary number isn't 607. And it isn't even 22. Nor is it 22/607 or 22/(8+22). (which, tbh, is pretty scary)

The scary number is 40%.

Sure, it's "just" old people with a high probability of dying. But I have several elderly relatives. I'm not enthusiastic about losing any of them.
The average age of coronavirus victims in Italy is 81.

The average life expectancy is 82.

Before "throttling" the next person that says it, have you considered these people's opinion that this will not be anywhere near as bad as a regular flu season and far from a severe one which is over 600,000 deaths globally? There's a good chance corona is displacing a lot of the deaths that would have occurred anyway due to the flu.

As far as things are going, the infections and death toll is nowhere near what flu has already inflicted on the global population in the last 4 months.

Why are people not taking the same precautions for the flu in the last few years? Why do people suddenly care so much? It's very much a media driven situation.

SARS in 2002 had no cases anywhere after two years of outbreaks. Something to think about. History can look back on these comments here and judge.
Germany or France are only 4-5 days behind Italy in number of infected. (Germany 1100 : Italy 7300).

As for number of deaths in Italy - they are already in warlike conditions where patients are going through selection and some are simply left to die.

You're completely mistaken. It's not an "external database". That's a regular, ~600kb interpreter download from kx.com

> In this case it seemed that it was just doing a binary search,

Yes. That's all okon does as well, they just do it over a B-tree instead of a contiguous list. If you read the writeup you'll see the author actually eschewed using a contiguous list for reasons of random insertion then took to a B-tree generation algorithm that couldn't handle unsorted input. I suppose they just forgot what they were doing at some point.

> but it was using an already sorted dataset that the OP of that comment wasn't using.

Again, you're mistaken. The author (Stryku) might not have known the sorted file existed, but the first thing they tried to do was sort it. They just had a problem sorting a 22GB file because they were using terrible tools. They had to make tools because they didn't have any good ones. The rest of their algorithm took advantage of the fact the input (to these later stages) was sorted.

> Well, I can't get anything out of this.

> I can't honestly believe anyone that says that's a good way to create code.

I spent 5 minutes to write something (in q) someone else wrote over twenty days (in C++).

I can't honestly believe anyone that thinks spending twenty days on a problem is better than five minutes.

If you can't get there, it's going to be really hard to talk about what's amazing in k!
I'm not saying that the reaction wasn't warranted initially when we had no idea how bad the disease was. What I'm saying is the level of panic, especially now, is totally unjustified. The hoarding canned goods and battening down the hatches. Insane relative to risk.

The biggest advantage of this technology is not reducing labor cost. The Amazon Go stores have lots of employees inside the stores doing different things. It's about increasing traffic. How many times you went inside a store and left after seeing a long line?

It can have other benefits like stealing alerts or whatever, but those I think minor. One problem I see is that Amazon is a retailer so many of the potential customers for this would be reluctant to do business with a major competitor. I'm still waiting for this to be implemented in WF.

Coronavirus: ‘We must choose who to treat,’ says Italian doctor
Yeah, I'm not sure why I was downvoted. It was a leading question to point out that "3 orders of magnitude" isn't far away at all.
Yeah I heard that all years before.
My SO is significantly smaller and lighter than me and when we moved together here in Germany we went to one of those "always sale"-shops that are all over. The guy talked to us for almost an hour. We tested mattresses and bought one we thought might be good for ~1000€. 2 years later(!), it already felt like it was getting worse, she was rolling on me, we had back pains and a year later we really needed a new one.

Fortunately a mattress seller became famous at the time in Germany for breaking the monopoly here and getting all the hate from the lobby. You know what he did? He sold the same mattresses everybody else sold but significantly cheaper. The margin was just ridiculous.

After being "banned" and not being supplied shortly after he started, he came up with his own mattress. 100€. Just foam.
We had it for ~5years now and I never slept so good before. The mattress have been tested as the best mattress on the market for many years here in Germany so it wasn't just us.

I know the US market is different because people seem to value ridiculous sizes and design over health and usability but this is what actually helps this scammy market to rise to those ridiculous prices.
In most places yeah which is why the kind of highly instrumented self reflection of the sentiment like the yield curve inversion can be dangerous. It's not a sign that says there's going to be a recession it's just a sign the people in that market think there will be one.

But Clojure is neither widely known nor widely used. The last Clojure survey was done by just 2500 people.

The top ten languages are all two orders of magnitude more used than Clojure. They are mainstream. Literally they have millions of users. That's the definition of mainstream. Mainstream pop: the music most people hear and which dominates the charts. No one would claim that free jazz is mainstream, even though it has some stable fan group.

This is just an observation that doesn't contribute meaningfully to discussion, but ...

Twenty years ago this web site would 100% have looked like an April Fool's joke.

Don't know what to make of that. Maybe it's that although retail feels almost exactly the same as it always has, under the hood lots of parts have really been moving, and I just haven't noticed?

The parallel observation is that when Gmail was announced it totally did seem like a prank. You're offering how much storage for free? for everyone? How?.
"Reddit you're bound to the shallowest lowest common denominator content"

If it's infeasible for the business to operate ethically, the business shouldn't operate.

But the resolution isn't impossible, especially for a company of MindGeek's scale: Remove anonymous uploads entirely. Require channels establish their and their performers legal identity (which for monetization, many have to do anyways), and require metadata on all performers in any video (presumably allowing them to publicly display as anonymous or with a stage name as adequate), and verify the consent of those performers to be posted on that channel.

At this point, I think Robinhood has to be a dead brokerage walking. I cannot fathom any new potential customers looking at brokerage options today and deciding that Robinhood best suits their needs. Their largest competitive advantage was the free trades, and one can find that at most of their competitors now. Existing customers are also leaving (and possibly suing). The future looks pretty grim for Robinhood.
I think it's too early to say. For me the real problem with these companies is VC money seeking VC-sized returns, which often come from getting outsize market power (e.g., the FAANGs).

I think the DTC companies mostly can't build the moats needed to make that kind of money. So I think a reckoning is overdue. But once key players can no longer subsidize each sale, we'll find out for sure where the store-vs-DTC balance is.

My personal guess is that plenty of people will keep buying DTC goods, and that many categories will be more than competitive with brick-and-mortar competitors. So I expect DTC mattresses will be a good business, even if none of the current big players survive the culling.
I'd love to see this at airports or something. Kind of hard to imagine in a real supermarket but maybe someday.
Mozilla has lots of policy but Firefox has very little policy enforcement. This is important for practical reasons I explained only the other day.

For example Firefox doesn't check for SCTs so if you show my Firefox an apparently brand new certificate for which there are no SCTs (because maybe it's actually bogus) it will carry on as if nothing happened.

It also doesn't check validity periods. If you show Firefox a certificate from Let's Encrypt claiming notBefore 1986-03-02 and notAfter 2024-09-16 it considers that seems fine, never mind that the Web PKI didn't exist in 1986 or that nobody is allowed to issue leaf certificates that last almost 40 years - it doesn't care about that.
For the longest time, a one-size-fits all product was Twitter's strongest value proposition. I disagree about the single model of discussion, and its inability to handle longer blocks of text. To me, these are some of the most significant ways for Twitter to distinguish itself as a social media platform. I don't think Twitter will ever be a place you go to for a quality conversation. It was never intended for that. Almost everything they did to enhance their platform made it worse.

there isnt much training required. I worked in a BSL 3 lab with aerosolized tuberculosis and the training was like 5 minutes.

Even if you touch the mask with your hands and it is contaminated, if you wash your hands after taking the mask off you will be fine.

The "you need training" is part of the media agenda.

I agree that statistically masks wont stop the virus from spreading in the public. While masks used by health care workers will stop the virus from spreading to health care workers. The reason is that most of the public wont use masks while all health care workers will.

That's the thing: Your customers shouldn't even be part of the equation.

Healthcare is a HUMAN right, not a workers right or a "if you have enough money to pay for it" right.

Ideally, your customers and their employees shouldn't have to worry about this at all. You are just another middleman standing between human beings and their health.

I see no reason you should exist. You aren't innovating or making the world better. Clearly your purpose extends no further than to create profits for shareholders.
Off topic here. But what's kinda interesting about covid19 is that a significant amount of the fatalities appears to be associated with cytokine storm syndrome. Suggesting that the effects of the infection might not kill you, but your body's immune system overreacts and kills you.

"There's nothing to do here."

Maybe. I imagine it's a trigger for some people to review their investment mix. Not saying panic sell at this particularly bad moment, but downturns are an obvious heads up for people that assumed everything would constantly rise. Changing your mix for future deposits might not be a bad idea if your current mix is higher risk than it should be for your age.

Amazon wants to spread this to more than just their stores. It's a mild problem now but most things are when new tech is introduced. Accessibility doesn't matter when only a few sites are on the web but becomes critical when the web is the default way to access information.
Is that really misinformation, or just people having different information (or understanding of information) than you have? I have talked to actual front-line doctors who have mentioned running out of medical-use-approved masks and have had to get emergency exemptions allowing them to use other N95s wherever they can find any. The shortage is already real, and likely to get worse since we're likely still in the early stages of this outbreak.

So yes, it's true that widespread use of masks is somewhat beneficial. It's also true that we don't have enough for absolutely everyone, and that health care workers being unable to procure masks would be detrimental. The question is not which is true, because both are. The question is what allocation best serves our public-health interest. People - even people much better informed and closer to the issue than either of us - can reasonably disagree without slinging the "misinformation" label. If that belongs anywhere, it's with people who present only one side of the story and then follow up by attributing motives they couldn't possibly know. ;)

the risk reduction is actually very high. But the probability of being in the presence of the virus is very low. Health care workers treating infected patients have a 100% chance of being exposed so epidemiological risk reduction is large.

I think the "useless" part actually refers to the the fact that the public at large wont be wearing masks so a few people wearing masks might protect themselves, but does nothing to alleviate the overall spread of the virus.
