Whilst Amazon Go is cool, that's not an argument in its favour. That's purely a US specific screwup. In the rest of the world you can clear contactless transactions in a few hundred milliseconds with competent retailers; that's why it's possible to tap your way through the gates at busy London Underground stations. And retailers love contactless exactly because it's so fast and it lets them reduce staffing/handle more customers.

I don't know about your part of the US but it's now pretty common everywhere in Europe to have nearly unmanned retail stores. All the checkouts are self service. You can grab a portable scanner at the front, scan items as you walk around grabbing them and then tap your card at a checkout kiosk.

Amazon's implementation sounds even easier (no scanning required), but in terms of raw throughput it's probably only a bit better.

But whether you start your retirement at a time the market is down a lot or up a lot can make a surprisingly big difference on how long your money lasts, if you don't adjust your spending.
Completely random and off-topic. I'm in the US and used to 12-hour time. I personally prefer 24-hour time, and am comfortable with 18:00 or similar for a time indicator. I don't know that I've ever seen a 24-hour time with am/pm attached to it. Is this common?
Certainly, very few people possess the brilliance of Jobs or Musk. But, I doubt Twitter and Square demand the same sort of brilliance from a leader as Tesla, Space X and Apple do/did. A quality that Musk and Jobs have that Dorsey might, is their work ethic, which is far more common than true brilliance, and probably more relevant to the challenge of being the CEO of multiple companies.

Although, maybe being in charge of multiple companies diluted the efforts of Jobs and Musk, but it was made up for by their brilliance and leadership skills. An hour of effort from Dorsey might be equal in gains to five minutes of effort by Musk. If that's the case, then maybe you're right.
1. The culture and processes should supersede the org chart. If that's not the case, go work somewhere better.

2. To some people levels matter for career growth and validation. Other people don't give two sh*ts. For all people looking to switch jobs (as we all inevitably do) the levels make a difference in recruiting, salary negotiations, etc.

Although I agree with your statement, no one tried to solve the actual problem with purchasing a mattress: finding a mattress that fits you well. The process changed from trying many mattresses in a uselessly-short[1] in-store test (with almost no information about what you're buying), to buying a "One size fits most" item for a product where that doesn't actually exist[1] – and without even trying it.

[1]: From "Choosing the Best Mattress: An Experiment in Testing Whether Individuals Choose a Bed That Leads to Improved Sleep," https://www.rti.org/sites/default/files/resources/rr-0016-11... : "The mattress that individuals chose as optimal before the randomized, controlled phase of the study did not predict either the actigraphically determined best mattress or the best mattress as determined by reported sleep quality."

City centre shops (downscaled versions of the big chains like Sainsburys, Tesco) in London are almost like this today; you walk in, gather what you want and pay using self-service check-out. There's no more than one or two cashiers but perhaps a dozen self-service checkouts. There's no interaction with anyone.

Amazon is always putting up ads for me based on my purchase history, but they're never what I wind up buying. I have no explanation for what is wrong with their algorithm.
I have been reviewing the situation with a colleague of mine, and we have now realized that the new measures are not enough. It makes no sense to allow burger king or any bar to stay open util 6 p.m. And it makes no sense to allow to go to work for any undeferrable (or also deferrable) reason. The only effective measure seems logically to be quarantine, and for me and my family (2+2), from tomorrow afternoon quarantine will be. The government will finally arrive to the same conclusion, but a later stage. At the moment they seem to be still trying to balance the counteracting of the epidemic and the economic damage, but to us that's not the correct thing to do.

Linux and open-source conferences: List of what's canceled or going virtual
This is really great work, but I still miss my quirky xscreensavers.
The question is whether they'll go up as much as they used to - with global population growth slowing down, there is a case to be made that the 7% long term growth that many people treat as a fact of nature is not in fact a long-term thing.
That's exactly what OP's sarcasm is implying.
>Will people still be working in stores with Just Walk Out technology?

>Yes. Retailers will still employ store associates to greet and answer shoppers' questions, stock the shelves, check IDs for the purchasing of certain goods, and more - their roles have simply shifted to focus on more valuable activities.

I think this raises questions about ethics in technology. Not to mention the creepy cameras watching your every move, retail is a large source of employment for non-academics and we're slowly phasing out the need for people to operate stores. Here we've seen the self-serve checkouts which has one staff-member supervise 8~12 self-serve checkouts. The amount of manned checkouts has reduced so drastically that there's only one or two or in some cases no manned checkouts open.

From the statistics I’ve seen, unless there’s effective quarantine and countermeasures in effect, you can expect an order of magnitude (while most of the population is not yet infected, obviously) about every 2 to 3 weeks. Yay for exponential growth.
I.e. Amazon has long term thinking.
Pareto efficiency does not apply, because it is a theoretical construct that assumes perfectly rational actors. It's useful for thinking about the market, but not an actual law.

(For a more humorous statement: https://www.youtube.com/watch?v=oap6_U8-HvI)
I do not believe it is left-wing or right-wing specific behavior. We are seeing the issue being handled the same way across the world. So, making a political statement does not contribute anything. If you remove the "left-wing", the point would be equally valid.
Way too soon for that, but it will be investigated in the future.
Yeah, so long as the people delivering the groceries are able to completely avoid contact with the infected, then that can work. However, having reasonable reserves at home and not needing others to delivery your groceries in the first place is going to be more effective.
It’s not an entire VM. Where did you get that idea from? It’s less than a DSL - it’s Java with a modified compiler library.
See, I was thinking of it the other way around. If you're going to change things, you might as well go all the way. Because it's not like they're fooling anyone right now.
> One more reason joining and splitting strings with security impact is a bad idea.

Doing it in a standard/shared library is more secure than bespoke code on each page, since at the very least as we witness here it can all be updated together as needed. You can add additional abstraction, but someone eventually has to do this work.

Even web browsers themselves aren't immune from bugs in "joining and splitting strings with security impact" for URL comprehension. All you can really do is try not to re-write known secure code.

Plus this buggy RegX was from the standard on URL parsing:

Fully agreed, this is a big concern of mine as well. We've got a 2 week trip planned to Italy in May, but that is likely to get cancelled this week based on the growing concerns throughout the country. I am fully expecting to reschedule our same trip later in the year, but until the virus starts to slow down significantly, I'm not comfortable rebooking.

We do, in a team of 10. We have a very strict rule of being prepared before standup and going through the standup list quickly (< 1 min each). We also make sure to keep our list of tasks focused. Any sidebar discussions are taken until the ending of the meeting and all stakeholders who care can be part of it.

I think for us at least, just having the team all aligned on wanting to finish the meeting as fast as possible helps keep it running quickly and smoothly.
If the market drops less than your put strike price, you can sell the puts and keep the shares. If it drops more, you exercise the put, which results in selling the shares at the strike price.
You ask your broker for the physical copy of the stock certificate. The buyer asks their bank for some physical cash. They hand you the cash, you hand them the stock certificates. Same as buying or selling anything else, basically.

Of course, for a transaction of a certain value, you wouldn't want to hold the cash or certificate, so instead you write out a contract and sign it at the moment of exchange. Which is the same as buying or selling something else (e.g. car, house) beyond a certain value.

URL parsing is a mess. The specification is poorly defined, and different libraries and/or servers handle them differently. This is one kind of attack; many SSRFs exist which leverage that weakness.

The regex approach, btw, is even worse. Parse your URLs before doing things with them.

Not sure why you feel the need to say that anyone who is conscious of their grocery budget is irrelevant to an automatic system? You don't say this, but that basically implies that anyone who does so is 'beneath' this tech/convenience.

Unreal, a month ago (February 7th) I was posting this news story [1] related to the city of Shenzen which was about to be put into some form of lockdown, it only received one upvote. A month from that event and we have an entire European country (a G7 member to add) under lockdown. I guess the normalcy bias [2] was too strong for too many people until reality hit us hard in the face.

Inverse and short ETFs are terrible for medium to long term holdings. Because it resets each day. Here is an example of what this means:

Consider a hypothetical index having a volatile week (like these days). The index was at 100 on day 1, dropped to 90 on day 2, recovered back to 100 on day 3, rose to 110 on day 4, and finished the week flat at 100.

If you were invested in an ETF that tracks the index, you would neither lose nor profit. But if you were invested in an inverse ETF, you actually lost money overall: the percentage day change of the index is -10%, +11.1%, +10%, -9.1%. So the percentage day change of the inverse ETF is +10%, -11.1%, -10%, +9.1%. Add one and multiply these, and you would have lost 4% overall. This is not even accounting for the increased expense ratios of these ETFs.

But wait, here's more: if you were invested in a 2x leverage ETF, you would have lost 4% as well! The percentage day change would be -20%, +22.2%, +20%, -18.2%. Add one and multiply these and you arrive at the same number.

This is simple math. And I think, this should convince everyone that inverse and leveraged ETFs are terrible in typical volatile market scenarios. Link to spreadsheet: https://docs.google.com/spreadsheets/d/1XEyE4DxXOilXz4PnGBSX...

If you really really want leverage, consider having a long /ES future with suitable level of leverage, and roll quarterly. For the typical Hacker News audience who are not finance professionals, don't even think about shorting the market.

When stocks crashed in 1929, it was different. In the US we got the New Deal, which still exists in some form. In Germany we got fascism and then a divided Germany for decades. The 1929 crash had effects felt to this day. The DJIA did not recover its 1929 level (not inflation adjusted) until 1954.

The kings and queens of Europe could point to how things never changed over the past millennia, and moved forward as they always had, until Charles I had his head lopped off in 1649. Then things began changing.
Medical personnel also have training to not touch their face, wash their hands repeatedly, and use disposable gloves.

Standard people do none of these.

N95 masks are useful in two cases: 1) medical personnel with training and 2) people actually sick so they don't cough it onto others.

For normal people, N95 masks have significantly decreased effectiveness since they don't cover your eyes.

Pinebook Pro – After 2 months, impressions and Setup Tips
Could you provide a link to where "the left" has said the only virus is racism? I wasn't able to find anything, but admittedly my Italian is not great.

I find it hard to believe, and given Italy's recent problems with the far-right surge, it seems to be more fake news.
You're right, I had simply assumed that F# was readable. Interestingly, four proofreaders did not pick up on this either.

Parenthetical aside: I could have been rescued from this by a sufficiently advanced Markdown renderer, and in fact the HTML source is annotated with `lang-fsharp`, but that metadata did not make its way up to the reader.
to deliver 1500 watts at 12v through one pin would be 125 amps. 5 pins each with 25A I would think you’d want at least 14 gauge per pin and even then I think they would be rather warm.
I hope (and suspect) that the ECB (and Europe as a whole) will financially stand behind Italy, no questions asked (I'm a fellow European).
If the end goal was to transform all WF stores in the near future, I agree. However, I don't think that is what's happening here. For that transformation to work well, the whole "cashier-less shopping experience" needs to be normalized with the general public, and that's where the brilliance of Amazon's strategy with this tech can be observed.

WF has already served Amazon well by being a test bed for grocery delivery optimization, no need to screw up a profitable existing business with any additional radical changes. That's what Amazon Go stores are for, and now they can sell that tech to other stores. Once the tech is mass-adopted, they can smoothly switch all WF stores to "just walk out" tech with very little complaints, as that's the experience people would be already used to at all the other stores
No, at least not in Italy. In fact, I don't think it makes any sense.
It reminds me of all the Uber and Airbnb clones that didn't recognize that the primary features that created their success was the commoditized nature of the seller and the ability to tap into latent supply (and circumventing the established regulatory environment, but that is a conversation for another time).

An Uber for home cleaning was never going to work because it is tough to commoditize inviting someone into your home and both the cleaner and the user have an incentive to cut out the middle man as soon as a solid working relationship is established.

An Airbnb for massage therapists was never going to work because there isn't a huge supply of people who are capable of providing the service but are unable to find customers themselves.

An Uber for delivering food works because no one cares who delivers the food and because it is a service that almost anyone can perform.
The "competition" that Google is bidding against is all the other ways that people capable of finding this sort of bug might choose to spend their free time.

It's still too soon. RAPID international transport has only been around for a mere 50 years or so. Before that it used to take a month or so to move from one side of the world to the other. Now, it takes just 24 hours.

Fifty years is barely two generations. In some countries, the intermixing and intermarriage of different nationalities is well underway (US, Australia, etc) but in many others it's still very early days.

Maybe drifting a bit, but I hate the business model Vector has. They have reasonably good software, but their Canoe SW has that horrible scripting language that is... well, horrible, but that everybody uses and because it's historically been used and the vendors have all the test panels and whatnot in it, the developers are locked in to pay for exceptionally expensive SW for a sub-par product.

Better than most other sw in automotive but it pales with open-source SW that does more complex things in other fields.
