Many interesting comments here. I think to a large part I came to the conclusions in this article myself by trial and error. I agree as someone said here that you have to really become a student of your child. Don't just try the same old rubbish that doesn't work. Try other approaches and make mental notes of what works.

I don't naturally get angry, so I simulated anger just to see if it worked. My experience is that anger and scolding sort of kind of works but is very inefficient and often has diminishing returns. You reach a point where simply getting more angry doesn't work. Quite the opposite it just makes things worse.

I was positively surprised by how much more efficient positive reinforcement was. Just a little bit could often create a lot bigger change than lots of screaming and shouting could produce.

The problem is that it is often far more complicated to do. It requires more thinking, because it is not always obvious what the opposite of the bad behavior is and when you should praise.

E.g. my second child would go ballistic on the changing table. It became almost completely impossible to put him there because he had so many negative associations from being held in place while being changed. I realized I had to make it into a positive experience. My solution was to bring him there when he didn't need clothing or diaper changes and only put him there to do fun things. Gradually I got him to think positively about lying on the changing table, and then I could actually start praising him for complying with getting changed. But just realizing I had to take him there to do something entirely different from what the purpose of the changing table is wasn't obvious to me at first.

So my advice is, try to figure out how you child thinks. A lot of this comes down to having empathy with your child and seeing the world from their perspective. Once you know that you can more effectively employ various best practices.
Machine Learning Made Easy – Decision Trees
Amazon didn't build this to generate extra revenue on 'impulse buys', they built it to collect a fuckton of data. And while they own the retail space, delivering fresh food isn't easy with their infrastructure. I'm guessing they'll Beta the Amazon Go system for a few years, then offer it as a service to existing Grocery chains. THEN fresh food delivery will be a snooze, since Amazon will have access to the Whole Foods down the road.
> What's always so funny to me is how the millennial generation in general has a hugely negative view of Walmart for paying poorly and destroying small businesses, while having a positive view of Amazon.

The difference is that while both may offer low prices while destroying small businesses, the customer experience on Amazon is great while the customer experience at Walmart sucks.
I personally think that if "general AI" (that is, something akin to human-level or beyond, and possibly sentient) ever happens - it'll happen by accident, and will be an emergent phenomenon that we won't be able to explain.

It will surprise all of us, and will likely be a "earth-shaking", akin to an extra-terrestrial alien contact. Perhaps even more so - because it would be a hard example against the idea of dualism (unless it arises from a quantum computing system - then humans can posit an "out" of course, regardless of whether it is true or not).

All pure speculation, of course. I honestly don't think we'll be able to "design" a general AI - we don't even understand how sentience and consciousness (among other things in the philosophy of mind) even works or exists in human brains. We understand the gears and wheels, but can't describe the factory.
But that card could be maxed out.
Then those (like rent, as I mentioned) are the much more compelling arguments.

If I'm unable to work for months, I'll have to draw down my emergency fund (probably move somewhere cheap to slow the burn rate). If in Europe I don't have to save for this, and can freely spend all of my paycheck, then that's a huge benefit. Ditto with retirement, which takes ~15% off the top of American salaries (unless you are irresponsible or in crisis so not saving for it).

Preschool is a valid point; moving to a good neighborhood is captured in rent.

I'm just saying healthcare and education aren't the interesting arguments. Housing costs and socialized savings plans are.
Since you're 100% right I wouldn't call that cynical. It is indeed another approach to create a unified messaging standard. And yeah there are plenty and I haven't even looked at every single one in detail to be able to reject them. But that's definitely an exercise I will try soon.
My bank limits passwords to at most 5 alphanumerical characters. Yup. Five. There are over ten times more possible customer IDs (10 digits) than passwords.
BlockCDN Releases New TV Set-Top Box for Cryptocurrency Mining
I was working as a corporate lawyer, and I posted a Show HN [1] before going to lunch one day. I came back and it was at #1, and it stayed there for over 12 hours. This led to a feature in Fast Company [2] and press in over 20 different languages. After winning a couple startup competitions, I quit my day job and now do BeeLine Reader [3] full-time.

We have 70k users on our first-party tools, plus many more on our licensed products. Our tech is licensed by the CA Public Libraries, CNET, Bookshare, and others. Our funding comes from the Intel Edu Accelerator (ICAP) as well as various awards for education and social-impact entrepreneurship [4].

I really appreciate the feedback from the community, which helped me understand what the market opportunity was and what our customer segments are (didn't realize how big edu would be).

My favourite current HTTP request router is https://github.com/pressly/chi

The list of those using it in production includes:

- Pressly

- Cloudflare

- Heroku

- 99designs

- Origami

- IT Jobs Watch

- CrowdRiff

At Cloudflare it's our default router for internal APIs, which are all written in Go.

(and yes it uses a trie)
>A machine learning practitioner does NOT assume reality actually has a random forest out there in the world somewhere, and as a result needs to prove far more general (and less accurate) convergence results for the random forest.

Of course, most of the time nowadays, "throw a neural network or an SVM at it" doesn't really require strong convergence results... even though there are some nice analytical results for support-vector machines.
There is.

The problem is that the manufacturers aren't listening and don't care.
Out of curiosity, what bank is this?
Good luck with that. The customer is always right.

> because somebody would be able to steal a product by discreetly removing a tag and then walking out of the store.

That's already handled in grocery -- people can mess with regular barcodes if they want. it's a known cost of business
You get paid extraorbitant sums of money to sit in a chair and think about imaginary problems. You don't stand and work all day. You don't change the world in any way. You sit at a computer and punch keys all day, and you have the audacity to bitch and moan about your precious feelings when you havent worked a hard days work in your entire life.

You're literally an adult crybaby.
My take of the OP's point was that the deep general stack was unnecessary and decreased reliability. My read was that they think your self driving car software shouldn't also be able to run arbitrary python scripts. My argument is that it's practically irrelevant to reliability. I would not be surprised if in the future you could download an app to your iPhone, connect your phone to your car, and have the app drive your car. Sure, maybe having a specialized real time o.s. without any higher level interpreters could be more reliable in the early days, but the gains from rapid iteration you'd get from allowing cars to be driven by apps running on higher level abstractions would be worth the trade off, and over time the latter could be iterated upon to achieve practically the same reliability as over-engineered systems.

Maven solves the problem Ivy is designed to solve, but it also solves the build problem. You may just think of it as a "build tool", but I think of it as a "build and dependency management tool". There are build systems out there that don't solve dependency management (obviously Ant is one of them, there is also SBT, Pants, Buck, and probably more I'm not familiar with). Ivy is a component of creating hygienic builds for these build tools, and it would be very sad if it disappeared.
Amazon is boasting it involves "computer vision, sensor fusion, and deep learning" so there is definitely quite a bit more going on than the UPC code. It also doesn't appear any UPCs are actually being scanned in the first place.
Crap mobile site.
In 1800's - "If you are a farm equipment manufacturer, you have to acknowledge that you are slowly corroding the farming sector, which employs most people in the country."

Even if they "acknowledge" it, so what? It's not their job to create extra jobs to replace the ones that they've automated out of existence. It's never been the jobs of the companies creating disruptive technology, like farm equipment or cars or computers, to do this.

It wasn't Ford's job to find new jobs for everyone who had a horse-related career; same deal here.
I would go further and say that static pricing will not be exclusive. No prices on the shelves but prices as you scan. Person 1 purchasing at 8am Tuesday will not pay same as person 2 Friday at 534pm.
if you don't want your purchases to end up in the cloud, probably don't shop at amazon.
I have three boys, ages 10m, 2.5y, and 4.5y. I can confirm that in my case (at least for the two older boys), pretty much all the advice in the article is correct. As I read, I realized that I have been occasioning upon the recommended parenting strategies almost by happenstance.

It's neat to see those specific strategies called out though - I can immediately think back to times when I tried that and realize, "ohhh, so that's why it worked so well." Should help me focus more on those strategies.
The whole thing is driven by camera input. If they have a reason to be suspicious, they can just rewind the tape.

Something I've always disliked about password rules is the "special" treatment of special characters. What makes one character special and not another? Is % special? Why? Can I use ½ in my password and have it count as a special character? How about 特别? What about Ѕ, Κ, and о? Does "special" mean non-ASCII, non-alphanumeric, not-on-the-keyboard or something else? Why is it that sometimes some "special" characters are allowed and others are not, even if they're right next to each other on the keyboard? Why require one? Is "P@ssword" really better than "correct horse battery staple"?
You’re Going to Have a Problem If You Don’t Optimise for Revenue
If you're talking about discount supermarkets (Aldi, Lidl, etc), then note you're not supposed to pack your groceries at the cashier, but rather put them back into your shopping cart and pack up by the packing tables behind the cashiers. This way, checkout proceeds much faster compared to almost all other countries.
That military budget does go toward a lot of jobs. How many people work at Lockheed martin, boeing, bae, Raytheon, etc. That is why congressmen keep that spending up because it ends up going to their counties, districts, etc.
It turns out the most people aren't interested in complex strategies to steal a grocery items while under intense video surveillance with ID verification.
These are purely assumptions based on what I saw on the video alone:

>If my friend and I walk out side by side, how does it know (if it does) which items are mine and which are hers?

Looks like the entry/exit is the same type of set-up you find at most large office buildings with the tap in/out gates (see screenshot: http://i.imgur.com/e7fDglY.jpg). I assume it only lets one person out at a time which also suggests your friend could only enter the store if they had an amazon go account and tapped in themselves.

>What happens when someone picks up an item and leaves without first doing whatever check-in/registration/setup is necessary?

Again, based on those gates, I'd assume you can't actually access the store without going through the necessary set-up first.

Personally, I'd like to know what happens if/when my phone battery dies in-store.

We looked at that, in fact it was my first recommendation, but the way it forces you to set things up is less than ideal. We may give it another go, but it was not conducive to just taking the data scientist's R code and exposing it as a web endpoint - it requires a complete restructuring of the code.
Change replicated to represented or modeled, and it's a true and useful observation. Maybe the author believes "replicated," or maybe he just didn't find the right word that day.

In any case, if I change that word as I read it, it becomes a useful observation to me. Just because I'm reading an authors words doesn't mean I have to accept those words as-is. I just got a useful thought out of an incorrect statement. :)

Wow, this is very well put.
It's a company entirely focused on web security.

Even with no conflicts of interest at all, it's obvious that they would have higher security standards than anybody else out there.
If they were trained on normal shopper, how long does it take for the first exploits to appear, like some ML-equivalent of tag switching.

Like I heard from HEB Central Market employee, that they had a hard time with their bulk self-portion coffee beans, where the price range is quite large yet the beans look pretty identical.

Like most bigger shops, I think amazon will just tolerate the loss without enforcing it too much, if it stays manageable and under enforcement costs, which includes a too negative impact on the general shopping experience.
I too find with Java (most of my career I worked with it) if you change hardware just slightly you can also get wildly different results making other users benchmark conclusions on GC and JIT not very helpful. Like your armpits the only benchmarks that don't stink are your own :)
Considering there are no cashiers or checkout counters, cash seems like a no-go.
> But I'd also have been more impressed with the video if they showed stressed-out parents with crying kids and their hands full as they've got their cell phones tucked between their heads and shoulders, rather than young people quietly grabbing a single item and leaving.

It's an 1,800 square foot convenience store in a yuppie area stocked with what appears Whole Foods like take and go food, not a Wal Mart Supercenter. It will be quite a bit different if they open a large store out in the suburbs.
"Deep Learning, as it is practiced, isn't intellectually deep. With a few exceptions, there is nothing comparable to the great discoveries of physics ... Progress in DL mostly comes from architecture hacking: tweak the network setup, run the training algo, and see if we get a better result."

To be fair isn't this what physicists do all day at CERN too? Smash some particles together, analyse the numbers, try to find patterns, tweak a few things and try again?

Popular German bank „Sparkasse“ has this great online banking system that allows you only 5 characters (Small and large, numbers, umlauts and eszet[1]). They call it a PIN (Personal identification /number/), but IMO its terribly insecure.

This is really interesting, but it confused me at first. Given the title and the problem posed in the article's intro, I figured this would be a dataset of sheet music, ie. the notes and durations specified in some printed music. However, reading more it appears to be focused on recordings (ie. audio) and annotating those recordings with information about where each note starts and stops.

So to me this seems more directly applicable to transcription (ie. taking audio and turning it into sheet music) or synthesis (taking sheet music and turning it into audio of a human-sounding performance) than it does to composition or finishing unfinished works by famous composers. The output of the compositional process is generally sheet music, not audio, so it seems to make more sense that problems around composition would be trained and learn in the sheet music domain.

I'm not a machine learning researcher though! This is just my impression as a musician.

The problem is we don't really know what's lost and what's in storage.

Agreed - I think the potential value is quite high in unusual root causes. It's going to be very hard to make a system better at diagnosing 'flu' than a trained clinician. However, "flu-like-symptoms" plus a couple of subtle things in the history may point at a relatively obscure syndrome or whatever, which can be very difficult for a clinician to find.

Another thing to consider in any work like this, you really need to thank about what your false positives mean, in a practical sense. If your numbers are big enough (e.g. screening) and your positives result in a procedure (e.g. biopsy), eventually someone is going to die based on a false positive. This may still be the better option, of course, but you really need to demonstrate that, and think about what your sensitivity and specificity tuning needs.
Two points:

1) I don't think it just so happens that there are more old people in rural areas. It has to do with the respective characteristics of rural and non-rural areas rather than some historical accident.

2) I think even if you excluded those over 65 you would still find net flows as I've described them because rural areas have too many poor people and not enough rich people.

The larger point is that if you look at the United States as a country where we are all in this together, then it makes no difference if the people getting social security disproportionately live in Wyoming and the people making max social security contributions are disproportionately in NY. Individuals might be net contributors or recipients but if the relevant group is Americans than it all sums to zero. Most of the time that's the attitude most Americans adopt. But then when it comes time to try to justify the continued existence of the Senate and the Electoral College all of a sudden it's 1789 again and the States are independent sovereigns that merely turned over a handful of responsibilities to the Federal government. All of a sudden we aren't all Americans after all but instead Wyomingites that want to know why they should be ruled by New Yorkers and Californians.

Thanks for the feedback wyldfire. I am a dev on Azure Notebooks and wanted to mention we do allow viewing the content without login. However, to be in an executable context (jupyter) we require login. Our samples, in order to avoid extra clicks, take you straight into an executable environment.

Any notebook can be opened in an html view:

It sounds like you would like being able to view those more easily without logging in?

Thanks!

The Sparkassen in Germany do this, but they're not alone in doing so. They lock you out after a couple of attempts, so brute-force is out, but it's still dumb.
- that's exactly what it is. And the way I see it, actors are an implementation of OOP (in it's original meaning) so I would stick with "everything in an object"

- thanks =)

- I had that same feeling while writing it, constantly balancing my own ignorance with an acceptable level of vagueness

- call me the over-the-top guy. But the way I see, your vision has to be grand, if not megalomaniac if you want the essence to survive the collision with reality

- seamlessly migrating networked objects are one of the lesser over-the-top ideas though
Or just go to literally any other store and you won't have to defeat sophisticated algorithms to shop lift.

This is pretty standard for dealing with enterprise clients. They literally just want a copy of your code in escrow so they're not left hanging if you go out of business. They usually pay the escrow costs and you ship a CD-ROM or something. In my experience, this just happens once and nobody thinks to ask for updates once it's done.
We are talking about people misplacing goods in a store, are we not?

Perishable goods are a subclass of goods in a store, are they not?
Let's say a service does not require you to change the password. You are then "compromised once, compromised forever", at least until you change the password.

Let's say it requires you to change it every month. You are compromised at max for a month, right? If the attacker changes the password, you will notice, and make a different password, which will lock them out since they don't know the new one. So they won't change it, but they will lose access next month. This is good...

Except if you allow repetitions of old passwords. In this case, the attacker can change your original password to 'aaaaaaaa' for a moment and re-change it back to the original one, which will reset the "one month" timer, leaving them with access. Until you change it, but the platform won't bother you with it since the timer never expires.
Related. One local bank I've used forbid typing out password on keyboard. They provide a virtual keyboard and you have to click your keys one by one.
