Trying to understand: WalMart is logistics, but their logistics customer is WalMart, and the only way in is to sell in a WalMart store.

Amazon effectively thinks outside the Big Box, and will let anyone sell anything within the Amazon marketplace. I'm not sure if third-party websites w/ Amazon back-end and fulfillment are a thing, but that's a possibility.

In which case, Amazon effectively sells a marketplace, ordering, and delivery logistics system to its merchandise suppliers.

Maybe. I'm not entirely sure I'm a fan of the "Company X isn't in Market Y, they're actually in Market Z" meme, but it's got utility.

The problems I'm seeing with Amazon now are on two fronts. One is that the actual product review/selection process stinks -- too little control over quality and relevance of what's presented. If I go to a third party, one specialising only in the products of interest to me, I can get a far more appropriate selection of items, and I value that.

The other is morality. Bezos is an asshole and screws people over -- techies, noncompetes, warehouse workers, competitors, and more. I've got a problem with that. I may be in the minority, but that is something which ultimately matters. Perhaps it's the only thing which ultimately matters.

Instagram password automated checks
Instagram shows this on one of my account:

Keep your account secure
Your security on Instagram is a top priority. Based on our automated checks, we've discovered that the password you use for Instagram is the same as one that was stolen from another site. We haven't detected any suspicious activity on your account, but we recommend you to change your password.

I wonder how extensive is their automated check and how do they compare it to Instagram credentials? Do they use the hacked credentials and compared it to their internal hashed password?
Thanks for the tips!

San Diego Airport Adopts Technology used at JFK and Cincinnati to Tackle Queues
I disagree. Not that I don't think that simple, reusable components are valuable; They are, and any developer should run tests before sending things off to the cloud. But having things work on developers machines is itself a code smell, because developers have access to them.

Your whole project should build straight from very fresh boxes, and doing builds on developers machines will never be fresh boxes. It's hard to remove the cult knowledge from a development team. My project just discovered a new unlisted dependency when doing a deploy, because every developer knew about it and installed it on their machine beforehand. It was explicitly listed in the build/devtools dependencies, but not supposed to be a runtime dep. Had the developers run tests on a fresh machine, they'd have run into it. (Of course, the CI team had also installed it on the CI boxes, because they used it for debugging.)

For a large class of tests, having the developers run them in the build environment is fine. But you also need to run them in the deploy environment, and to that end developers should hit the CI system. Every test that the CI system runs on each commit should be runnable before the commit. You should have tooling and spare capacity such that the CI system is used to run tests immediately before commit, not right after - That's too late. You should run them whenever a dev sends off for code review. You should run whenever a dev feels like it; If they're in a good spot, run the unit tests, run the CI tests, see what's broken.

Although personally, it struck me as very strange that someone who's just witnessed her partner being shot (and who is currently in some need of medical treatment) that her reaction is to reach for her phone and the live streaming feature of an app. I certainly think that falls under "evidence of an interesting new phenomenon".

Edit: I don't mean "strange" in any kind of moral judgement. My heart goes out to this woman and her child who had to witness this and who've lost someone close to them. I mean strange in the sense that this isn't how I would expect someone to react.

Police brutality has been a serious problem in the US for decades, and it seems that putting a streaming video camera in everyone's pocket might help shift the narrative back in the people's favor.

They didn't.

She was detained until the scene could be cleared. All those backup officers know when responding is that an officer called in a shooting and that there is a gun in the car. They detain her until they can get all of the information and then she is released so long as they are not pressing any type of charges against her.
This is mostly because Escher relies heavily on Google Polymer Web Components on the front-end, which are natively supported by Blink, and supported on other browser-engines through polyfills which don't always work right.
I'm not assuming anything. I know that despite whatever happened in this particular case (though it would seem rare to tell a cop you have a gun and then try to shoot him with it, and then be a cop freaking out, cursing and shaking over what you have just done, and by all accounts this guy was a super stand up guy, great school employee, no rap sheet, etc, etc, etc), that despite whatever happened in this particular case we have a problem with institutionalized violence against bodies of color in the United States, especially Black males. We have a structural problem with highly militarized police that believe they are fighting a war against the people they are paid to protect. We have a problem with holding those police accountable for their actions. The whole story is a long story, starting with slavery, continuing through redlining and segregation, etc but this whole story is a story about cops that kill more people in a day in this country than other industrialized countries have in a year. It's a story about unarmed Black men being killed at disproportionate rates even while white mass shooters are brought in alive and heavily armed. It's a whole story about a lot of things actually - a prison industrial complex grown bloated, a war on drugs that doesn't work, police training that is incomplete or wrong, complacent citizens, etc.

But again, I'm not passing judgement on whether this particular killing was "justified" or not. I'm just saying we already know the whole story, and the whole story is bigger than this particular tragic ending.
Thank you for your answer. It has been very enlightening.

Part of the problem I had with the videos had to do with the examples they were using (a shopping cart that stores data on process memory rather than an external db seems a little risky to me).

Because objectively, the Rift, in its current form, is vastly inferior to the Vive with Lighthouse touch controllers.

If I ever get a notification on my phone that isn't a human trying to interact with me I immediately disable the notification and/or app.

With email I often (daily) unsubscribe from whatever impersonal newsletter shows up in my inbox.

This is a benchmark I did with the versions of Rails and Phoenix that were current in October 2015.

select * from visits, plus conversion to JSON and delivery to a client on local loop. About 5000 records.

* Phoenix 140 ms

* Rails 248 ms

* Ruby without AR 219 ms

* PostgreSQL 2.97 ms, with no JSON generation and no delivery

select started_at, duration from visits -- JSON and delivery

* Phoenix 74 ms

* Rails 116 ms

* Ruby without AR 88 ms

* PostgreSQL 3.47 ms, no JSON no delivery

Single process, so maybe Phonix could get a larger advantage as the number of processes/requests increase. For the typical none to low traffic site there is little difference, the tool the programmer is more familiar with wins.

Edit: improved formatting.
Someone willing to explain the downvotes?
> A surgeon makes a mistake during a procedure, the response is not "oops." It is: you will lose your life savings, even potentially their medical license.

Medical errors are a significant cause of death. If the responsible clinician involved lost their life savings every time someone died after a mistake the US wouldn't have any doctors.

It also sounds like a lousy way to prevent medical error or to learn from mistakes.

Did you mean "mistake", or did you mean something like reckless negligence?
An excellent if obscure book. Interesting to find another fan.

I'm not convinced she's right, I think she's more right than most, and she's definitely interesting and well-researched.
That seems within the law. If she is a direct witness to a fatal shooting there would be a critical need to get her side of the story as soon as possible, and usually that would be done by detectives at a police station, not the responding officers at a crime scene.
Really? Nobody cares? Seems like the author does. Gotta be more out there, too. I care.

I know that :-) I still had to maintain and test our main application for some corporate users running IE 8 until a few months ago. And I can still see some IE 8 (less than 0,5 %) visiting our main public website. But it doesn't explain where does this figure come from. The percentage seems really high, compared to stats I've seen elsewhere.
After reading a few comments on how to behave when police stops you and how to tell them you're carrying gun I can't shake the feeling that this country is trapped in some sort of a deadly staring contest, if you blink you can die. You have armed people trying to police a nation where everyone can have a gun, and many do. With this sort of tension on a daily basis things will go wrong, someone will make a mistake, which seems to be what is happening every week. And then people see the news, get scared and buy more guns, because they feel in danger, and later you read more comments on how they should calmly explain that they had a gun when police stopped them.

It's not so much "a different interpretation of the standard" as the standard draft having changed and Firefox being the only browser that has implemented the change so far...
Cyclical behavior in business and economics has been noted for a long time, certainly since the Industrial Revolution, and arguably before.

I think it's very dangerous to speak of cycles of predefined lengths, which recur regularly. I think it is useful to look at dynamics, how they occur, how they differ, the specific technological mechanisms driving these, and what the future implications are.

The questions are deep, vast, perplexing, and far from settled. Carlotta Perez's book is mentioned here, I second that. Paul Mason's Postcapitalism argues based on Kondratiev cycles, and has a lot of strong anecdotal data though I question Mason's economic instincts. Robert Gordon's The Rise and Fall of American Growth is an excellent look backward at the period 1870-1970, and onward to the present, though I think his view forward is somewhat clouded. It's not that I disagree with his headwinds and projections of harder times ahead, it's that he's missed some far more fundamental drivers and dynamics.

Alvin Toffler's Future Shock also deals in technology cycles and their dynamics. I've only skimmed bits but suspect that would be insightful.

There's a bunch of crud written on the topic as well, but if you're interested in the question, you're not going to be short of content.

I believe this may only be a problem for certain generations.

People raised to be "native" with technology have several filters.

First, they realize managing notifications is highly important. They ruthlessly unsubscribe, block and restrict.

Second, different uses are compartmentalized between different services and those services are given different abilites to penetrate your attention. You don't get work snapchats. Slack has a snooze mode and you don't set up your mobile notification center to keep them around until dismissed.

Third, and perhaps most importantly, they aren't compelled to jump at every attempt to contact them. Messages can go unanswered, and life goes on.
I have been comparing the 2, at third glance they don't even appear the be the same query.

Second for performance as much as possible from the SQL building should be outside the function. Also if the query is that static, you should probably use the plain SQL anyway ;) Or maybe even build the SQL query string by using SQL alchemy outside the function, and then using the SQL generated by SQLAlchemy inside the function (if you don't like pure SQL, like for example compatibility).

I'd agree with you that some police are too heavy handed for the everyday situation. However, there are a lot of violence / gang problems within the black communities in the US. That leads to cities and police forces cracking down on those violent areas which leads to even more heavy handedness and even more distrust by those communities. Its a perpetual cycle.

It seems that we need a revolution on both sides for anything meaningful to happen. Sadly we probably won't see that happen anytime soon.

Hopefully we can at least pass some meaningful reform related to drug imprisonment which would keep a lot of people out of jail for petty things, which just ends up feeding the cycle to begin with.

There are definite points of contention on this. The Vive headset doesn't face nearly as significant a glare issue as the rift, it is far better for glasses wearers than the rift and for some people the improved brightness is a significant advantage.

Integrated audio is definitely nice, but not a deal breaker and the improved ease in reaching a comfortable setup is definitely and advantage, but it makes trade offs in other areas.

You could split hairs about where the trade offs were made (fov vs SDE) but the displays and optics are so similar that those dont matter.

After playing a bunch of Clash Royale I feel a lot like the author feel's about clash of clans.

Clash Royale actually puts you into a routine of opening chests. Setting things in the game before going to bed and then opening things first thing in the morning. Paying increases the speed of your progress.

This works well because if you do not play the game you make no progress and feel bad as everyone around you is making progress.

It doesn't help that every 3-4 hours you get a notification reminding you of the opportunities you could be pursuing in the game.

If anyone is playing Clash Royale I would strongly suggest turning the push notifications off for the game. It makes it far more enjoyable and it helps eliminate the schedule that it tries to impose on your life.

> The officer isn't an EMT and if he was really shot 4 times in the abdomen then nothing the officer has would stop the bleeding.

Hmm, not sure I agree with "he isn't helping just because he forgot or never learned first aid stuff".

For example, there is footage out there of cops shooting their own, and here is what "trying to help even though not an EMT" might look like:

I came from Dalian last month and the entire city seems to be under construction. Just in 5 years, the city has changed. There's a new subway, that wasn't even under construction then, and everywhere you look there's a new high rise condominium being built, often times just a couple of blocks away from another either under construction, or worse yet, a finished, but completely empty building. The city is trying to get people move into the reclaimed land in East Harbor, and bizarrely even a 19th century Parisian neighborhood... which is empty for 2 years except for an "American-style" kindergarten and a wedding photographer.[0]

It's clearly a bubble. It's hard to understand how any of these are going to be filled. There's no real place to invest except real estate in China, and even there it's full corruption. It's apparently not unusual to "own" (well, have a 70 year government lease on) on a property but not actually have the deed, because the deed has been lost somehow.

It's very weird.

I never said he forgot. Only that he is not a trained EMT with access to a trauma kit that would stop 4 GSWs. From the video he is also alone and has to secure the scene until backup arrives.

Even if he had a kit in his car, he can't risk getting it with a gun still in the car. From his perspective he felt threatened enough to shoot and the gun is still with the victim(s) which could be turned against him.

The video you provided was different because they immediately realized that the undercover officer was not a threat, and had multiple people on scene as well to start helping.

a follow-up related challenge is do you want HN to become the sort of website where anyone can ask, for example, "what is foo?" despite <foo> being a thing that that very same someone could have gotten reasonable answers/education about by just googling about? What is sex? What is algebra? How do I learn about computers? What is a website? What is a web browser? What is HN? Who is PG? What is the English language?

Are these acceptable questions for the caliber of people you'd like to attract and retain here on HN? Do you realize that some people are just gaming your system? Do you realize that some are carrying out stealth self-promotion, while playing innocent? Where do babies come from? Which key do I press to submit this comment? How do I use the Chrome browser?
