> The past
half-century of empirical research on this issue has provided
overwhelming and unambiguous evidence that minimal
guidance during instruction is significantly less effective
and efficient than guidance specifically designed to
support the cognitive processing necessary for learning.

> Our understanding of the role of long-term memory in human
cognition has altered dramatically over the last few decades.
It is no longer seen as a passive repository of discrete,
isolated fragments of information that permit us to repeat
what we have learned. Nor is it seen only as a component of
human cognitive architecture that has merely peripheral influence
on complex cognitive processes such as thinking and
problem solving. Rather, long-term memory is now viewed
as the central, dominant structure of human cognition.

> These results suggest
that expert problem solvers derive their skill by drawing
on the extensive experience stored in their long-term memory
and then quickly select and apply the best procedures for solving
problems. The fact that these differences can be used to
fully explain problem-solving skill emphasizes the importance
of long-term memory to cognition. We are skillful in an
area because our long-term memorycontains huge amounts of
information concerning the area.

> The aim of all instruction is to alter
long-term memory. If nothing has changed in long-term
memory, nothing has been learned.

I'll quit there, but that's only a few pages in and it's all quite good and definitely worth reading IMO.
I’ve had nothing but terrible experiences with IBM Global Services. With deals like this, the commission check is cut long before the problems arise.

To be frank, Fox has been parroting the same conservative rhetoric for as long as I can remember. It’s the same as it was during the Bush years and the Obama years - O’Reilly has been replaced with Hannity and when Hannity retires another talking head will take his place. On the other hand CNN, NYT, Washington Post, MSNBC have shifted so far to the left, they would be unrecognizable to a time traveler from 15 years ago. Remember when CNN was considered in the center of the political spectrum and one of the most “objective” news source around?
There is a pronounced bias in the mainstream media and it is not towards the right.
Here's a catch-22 comment from elsewhere on this post:

> Avoiding women in workplace is essentially sexist. And for non-sexists there is no reason to do so.

So you're damned if you do and damned if you don't. Given how easy it is for public opinion to shift, I certainly wouldn't want to take that chance. Who would want to interact with people like that in a professional setting? I wouldn't, and I try not to.
I was answering your question in a roundabout way: usually "wobble" gives very little information about the chemical composition of an exoplanet (other than maybe that it's a large gas giant).
I hope you realize that ripping DVDs and putting them up for streaming is pretty easy, everyone was doing it before Netflix was, compared to having a fleet of autonomous vehicles that can safely operate in a multitude of urban environments, something nobody has ever done before.

You have to question the leadership of a company that's willing to throw untold billions and counting on a long-shot bet that they'll eventually have these magical cars and everything will be fine.

Once Uber can do it, soon afterwards everyone can, and what makes you think Uber will do it better when they've already had to give up so much to invent their own self-driving car solution?

Their business model is completely ridiculous.

I personally feel like there's still room to build something that's more terse, yet equally as powerful as SQL.

get name, age -> (foos.id X bars.foo_id) |> get first(name) |> head

as opposed to

select name from (select foos.name from foos inner join bars on foos.id = bars.foo_id) A order by created_at ASC limit 1;

more regular syntax that looks closer to conventional programming would be nice. At the very least it would probably be easier to write ORM style libraries for as the grammar would be closer together and more regular
Peterson Center on Healthcare | Tech Lead / Manager | Full Time | ONSITE | New York, NY http://petersonhealthcare.org/

Our tech stack: Ruby on Rails, PostgreSQL, JavaScript (React), AWS EC2/S3 (via Aptible), Travis CI
We are a team of technologists, designers, doctors, and healthcare professionals on a mission to transform the US healthcare system into a high performance system so that affordable, high quality care is available to all. The Center is a startup nonprofit healthcare innovation lab with a significant initial endowment ($200M). Our advisory board includes healthcare and technology experts including everyone from Bill Gates to Toby Cosgrove.

We believe the biggest lever for reducing cost and improving quality of care is through changing the behavior of healthcare professionals. Our first focus area is on primary care, and we have built out an initial software-enabled service to help practice managers introduce evidence-based workflow changes, see the impact these changes have on metrics that matter to the practice, and sustain these changes over time (think of it almost like teaching the agile process to healthcare professionals).

We are looking for a hands-on tech lead/manager (http://petersonhealthcare.org/careers/software-engineering-t...) to be the anchor of our engineering team as we grow our headcount in the next year. A passion for improving the healthcare industry and driving positive social impact is a huge plus.

Please send your resume and a few words on why you'd like to join us to me (Shawn): sdimantha (at) petersonhealthcare [dot] org

century labor exploitation through digital technology and the service economy
The Falcon Heavy took five years to develop and it's basically just a bigger version of the same Falcon 9 rocket they've been sending up for years.

Even if you have a driverless solution today it'll take years to test it and get it certified.
That's been my experience with DoorDash as well - mainly in San Diego and Redwood City.
You are confusing earnings and revenues. Amazon had revenues for its retail business of $60bn. But, in order to get that revenue, they spent a lot of money, maybe even more than that. The IRS doesn’t tax revenue, only profits - and Amazon’s profit last year was $5.6bn. And it seems like they may have paid $0 to the IRS in taxes, although they paid quite a bit to foreign governments, which is deductible.
Probably for the same reason software developers can't estimate tasks. At least for me the problem is that I figure out the algorithm at a high level and base my estimate around how long that will take me. But inevitably there are platform gotchas, or the API doesn't work the way I expect, or I forgot/didn't know about edge case. (I've done this enough that I have an idea of what kind of things can go wrong now)

I think the optimists are thinking "oh, the high-level problem of image recognition and building a 3D model of the area around the car is pretty much a solved problem, great, done!" But in fact, it's all the edge cases that will kill you. What happens when it is dark and rainy and the car in front of you is black, with no license plate? What happens when the car in front of you hits something in front of them unexpectedly? What happens when the car gets a flat tire? What happens when someone doesn't look in their mirrors before changing lanes? What happens when your "there's a problem" solution (like, say, stopping or slowing down) is actually not a good solution?
> It's sustainable because we're on the cusp of the autonomous vehicle revolution.

We still have drivers on subway trains. When those drivers lose jobs to autonomy, maybe we can think about being on the cusp. Until then, I see it as a fantastic story that can be used to milk VCs for cash.

At <$4/hour, it's a better investment to automate a fast food restaurant like McDonald's or Burger King. They pay twice as much for labor. Pouring a coke and cooking burgers and fries should be a pretty straightforward challenge. They've already done Pizzas.
A pretty straightforward explanation is that ⅔ [1] of the tech workers in Silicon Valley are immigrants. Silicon Valley recruits outliers from around the world, and it doesn't make sense to apply US demographics to an industry that recruits from such a pool.

If you assume that the Silicon Valley percent of immigrant workers holds for Google you conclude that 6% of the American Googlers are African Americans, since none of the foreigners can be. About 2.4% [2] of computer science degree recipients in the US are African American.

21st century slave labor. Doesn't Uber and Lyft hall in majority of the profit?
That's the problem with exponential development. It seems like you're getting nowhere for decades, then all of a sudden it's starting to amount to something, and in the span of maybe a year or two it goes from impractical to plausible to obvious and ubiquitous.

The problem with predicting these curves is there's usually a confluence of factors that lead to that tipping point. When the right algorithms, hardware, and software are combined it'll be obvious in retrospect, but right now we're still fumbling around with primitive solutions.

When will there be a TPU-type device suitable for in-car use? When will there be adaptive deep-learning algorithms available that can work in the demanding real-time environment of a vehicle? When will enough testing be done that we know such a solution can work without endangering people?

It will happen, but pinning down when is very hard. You'll only know when you're close, and by then you're already flipping from impossible to inevitable.
I haven't read this study but I the past I've often found the depreciation figures to be higher than what they are in real life. They sometimes kind of assume you just buy a new car at the dealers and then two or three years later trade it in for a new car which means every three years or so you lose 50% of the cars new cost. Almost no one hard up does that. Get good deal on a 3 yr old car, keep it 5 yrs, your costs are much lower.
Ask HN: How do you distribute your personal utility library?
Pretty much every developer ends up with a utility library of various functions in their language of choice. How do you distribute yours when it's used by multiple personal open source projects? I'm working in Python and would like to just distribute a package to pypi but feel as though I would be polluting the repo with personal code that wouldn't be useful to a wide audience. An alternative I considered is a git submodule, but that makes it hard to version since submodules will track HEAD by default, and that obviously also forces a git dependency when I prefer to use hg.
A gas-powered, highway-capable, driverless car feels callous. I hope those algos are good.
Governments everywhere would function a lot better if there were more people like you in them.

I'm probably preaching to the choir, but government managers are deathly afraid to stick their necks out and say "no" to the ridiculous spec-by-committee approach to projects.

It's a lot easier to shift the blame to contractors, particularly when most projects take so long that they're obsolete by the time they go live.
However, the insurance provided by Uber and Lyft only cover when you have a passenger in the car -- they don't cover you when you are driving to pick up the next person. And your own insurance also doesn't cover you during that period, unless you buy a separate commercial rider.
The difference may be that there is no end goal with Herbalife.

With Uber and Lyft, once the self driving cars start working it will truly displace all the drivers. So perhaps they are just pawns in this endgame.
Very nice. I built a boilerplate Lambda app that puts a lot of this cost effective architecture into practice:

https://github.com/nzoschke/gofaas

One difference is that I use SNS for cheap email or SMS error notifications.
Which is a good first step... but if I'm injured at a regular job? workers comp will cover my own bills and lost wages while I recover(usually even if it was my own goddamn fault) - Uber drivers don't get that benefit, and they are a lot more likely to be injured on the job than I am.
> Aren't you sort of glossing over the fact that he is in high up machine learning position at a company that specializes in recommender systems? Doesn't that by itself increase the likelihood that he deeply understands implicit and explicit matrix factorization?

Sure thing, but someone in that position needs years of experience in recommender systems, as well as working with researchers.

Folks are hanging on to the PhD part of my claim, instead of the "PhD or experience" part. The fact is, a PhD + prior industry work means the person is close to a decade of relevant background, grad degree or not. They will unstick a co-worker far faster than an experienced backend developer with, say, a year of Keras experience.

> Side note: sounds like we do similar work. I work at Vevo, also do a lot of matrix factorization to learn latent factors of items such as artists, videos, etc.

Seems like it! Email me if you'd like to chat some more offline (it's in my profile).
This isn't the most unreasonable list I've seen, but beware you will break many websites with this, so you need to be prepared to deal with the fallout. Notably, a lot of the breakage is hidden in user.js, including:

* No WebGL or WebRTC

* Aggressive TLS settings (will break many websites)

* Mixed-content upgrading (Nightly ran an experiment on this recently and it also broke a lot of websites)

* No history

The text warns about this, but it should at least be clear why Mozilla doesn't ship this as default.
1 million is a laughable low coverage. Get into a single accident where someone has to get emergency surgery, a few months in the hospital, and then needs physical therapy to walk again. One million is gone faster than you can imagine.
Am I missing some detail here, or is this post getting downvoted solely because it's a faith based app?

I'm not a religious believer but surely a company has a right to build a meditation app targeting a huge segment of the population?

Very well then I contradict myself,
(I am large, I contain multitudes.)
It’s ok to share. You should try to talk to somebody about all this. Hang in there, man, and let us know how things are going.
Oh, it was awful. I was perhaps, 26, hardcore atheist. No mention was made of any of what was to come when I accepted the interview.

There was a technical interview with a very nice guy, who said I scored the highest of any candidate who had ever interviewed for the university.

Then, this sallow cow of a woman with a permanent look of disgust on her face conducted my "religious" interview on subjects like evolution, the Trinity, and my relationship with Jesus.

I tried my best to be "reasonable," but I'm sure I looked like a deer in headlights. It's impossible to be reasonable with unreasonable people such as evangelicals.

My position on spirituality has softened quite a bit as I've gotten older and had a few "spiritual experiences"... but sometimes I wonder if, in the intervening years, if it has occurred to them that beliving in provably false things like creationism, (remember, evangelicals won't even accept that "evolution is gods mechanism of creation"), doesn't make for a good engineer.
I drove for a few days as an experiment. What struck me was how low skilled work it is. No judgement. Just, it felt like having a really easy job.

And a little humiliating. I’m old, and with drunk kids being a little condecending, plus seemed like my car smelled like booze for days!

But, how low it pays and it shocks me there are ALOT of people with free time willing to work for sub minimum wage.
I think the disagreement is what the last 10% are. I see urban driving as part of the 90%. My 10% are rural gravel roads with puddles, snow covered roads and similar bad road and weather conditions.
Pretty sure atmospheric oxygen can be produced from weathering of silicon dioxide.
If just going by economic strength: US + any EU country. As a bonus, if you are of ethnic Chinese descent, you can look into one of the "greater China" regions of HK/Macau/Taiwan as well, depending on where you/your parents were born.

That combo would give you the ability to live and work freely in the three most important economies in the world (US/EU/CN).

what is the difference from gitbook
Sometimes I wonder how these projects are started; is it really that they go straight to “here’s a binding contract for millions”, without having them do any smaller projects in between?

If it were me, at the very least I would start with something small and say: “deliver this, let me see how it works, give me every last line of code for further inspection, then we’ll talk more”. I mean, have them build a mini-site or something and make sure that they’re competent before unleashing them on the entire payroll system, right? And you don’t need some grand familiarity with the software industry to plan that way, it just makes sense to start smaller and make sure you know who you’re really dealing with (and also spending less money if it fails).

I don't get it. Taxicabs such as in NYC are famously expensive to buy into, and yet drivers somehow afford it and make livings on them. So if they are clearly not losing money, why is it that a company that's supposed to be vastly more efficient due to use of computers can't make a profit? Are the tech overheads really that high?
I have three (US and two EU countries) and as far as I am aware the biggest hurdle is paying for multiple passport renewals.

I have had a similar experience. People hate change, and will do their best to not change their processes, ever, unless someone makes them (which rarely happens). They'd rather spends hundreds of millions of dollars inventing some new piece of software just so that don't have to spend a minute pressing a button they don't want to press.

I am convinced 90% of corporate IT software would be irrelevant if the businesses were willing to change 5 or 10% of their process.

>you can reasonably work under PhD level people and write code to test, scale, and deploy their ideas.

Which phd, though? All PhDs are not equal (see politics vs computer vision). Also, PhDs are hardly the holy grail of demonstrating capability, accuracy or intellect, especially given the reproducibility crisis, phds as a measure of any of those things should be used carefully.
In SF, I'd make $30 to $38 an hour over 40 to 70 hours a week. My friend cleared $2000 week driving 70 hours for Lyft.

My expenses were $400 a week, including car depreciation. I was leasing the car from Uber which is ridiculously expensive unless you do 60+ hours.

If you live with 8 other people and pay $500 month in rent, then you can make good money.

In cities that aren't SF or NYC it isn't worth it. In LA, it's 30% less income than in SF!
With Oracle involved, you've also got the strong possibility that the salesperson who got the commission check on the deal is long gone by the time the product is delivered. Turnover is unreal on some of those teams. I have a friend who no longer works there that had 100% turnover on their team in six months.
Except that the resources here are finite, and using them has side effects.

Gosh this is ridiculous, why do I even have to explain it. If someone starts wasting fire extinguishers by emptying them out a window, do you proclaim that "if one thinks that the fire extinguisher can be put to a better use, they can start using them for that better purpose next door"?
Recruiters, on the other hand, are paid up to 20% or so of the position's salary to get you to take it.
