The students paid for instant 24 hour access....they aren't getting it. If I bought a course and suddenly I couldn't access it for 2 days, I'd be pissed. And I guess the people asking for refunds now are doing it for an entirely different reason?

Yes, I am entitled to something with their platform, they make a lot of money from my content. A contract is formed, terms and conditions are agreed upon. Mail order law must be upheld. They have every right to combat privacy, but do it responsibly.

Why delete the course at all? A simple email saying "Hey, send us your id so we can verify you" would have been fine and done the trick completely. Give me 24-48 hours to comply before you delete the entire course and screw up a year's worth of work and marketing effort.

That would be an honest attempt to combat piracy. What they did was reckless.
I use this feature selectively in Safari now, and am glad to see it in Firefox. Eventually I'm sure I'll run into the problem of getting duplicate notifications from the same sites. I wonder what the solution for that will be... running only one browser at a time is not an option. Maybe I'll have to keep track of and choose just one browser per site for allowing notifications.

Why have two browsers open at once? So that I can be logged into Google services simultaneously with two different accounts (personal and work). Off topic, but would be glad to know if there's another way to do that.
Why? Our resources aren't infinite. Why is there any should about who gets to live and who gets to die? We can't help everyone live without eventually hitting resource constraints, can we?
Well, yes. Everything else I've mentioned is also dependant on cultural contexts that may vary dramatically over time. I surely hope Facebook hasn't won forever.

I agree - I wouldn't enable that option either, but at least it'd offer a better alternative for people who do like GIFs / GIF-like animations.

It's a bit ironic that the autoplay functionality of BPG is touted by some as a major advantage, yet the only reason it autoplays is because it currently has to be implemented in Javascript (bypassing the normal push-to-play behavior of web video).

If the people pushing for native BPG browser support get their way, the most likely outcome will be BPG implemented with the same push-to-play UX as any other kind of web video.

You forgot that doctors that accept medicare don't have any say in what they get paid for a service. The government decides. They (or the hospital/practice) also have to negotiate with insurance companies for payment amounts. Have you ever seen in the news where an insurance company stops allowing its customers to go to a certain hospital system because the hospital wanted to negotiate higher payments form the insurer?

I'm not an alternative medicine fanatic, but neither am I someone who thinks that Big Pharma is nothing but an evil conspiracy, but I suspect at the end of the day, these things don't get a lot of attention because there's no "miracle drug" that can be patented and sold for billions.

They fall outside the jurisdiction of the FDA (whether they should or not is debatable), but I wouldn't write any of these items off just because they are marketed as supplements.

I think the best we can say is that we don't know enough about them and their effects. Look at how often the "eat X, it's good for you"/"don't eat X, it's bad for you"/"X has no significant effect" articles we see... often where X is the same thing in different categories.
A friend of mine made a bot that connects to battery powered wifi sensors that have motion and sonar to detect if the restroom is occupied or not. Then he uses /gottago to see if the restroom is available.

He's also building a betting bot for in-office bets, like "how many builds do you think we will do this week" and it will pay the winner via the venmo API.

The Minnesota Starvation Experiment was such a poorly designed diet that it's not really relevant to the modern discussion of prevent obesity among a relatively prosperous population. According to Wikipedia (https://en.wikipedia.org/wiki/Minnesota_Starvation_Experimen...), the diet was based on "foods that were expected to typify the diets of people in Europe during the latter stages of the war: potatoes, rutabagas, turnips, bread and macaroni." In other words, almost entirely carbs, with practically no fat or protein. Almost every reasonable diet I know of (coming from the modern fitness community at least) focuses first on maintaining adequate protein intake as the top priority, usually followed by at least a reasonable amount of fat. While it may have been useful to understanding starvation in a population with food scarcity, it just doesn't apply when looking at obesity in modern America.

> Let's hope this becomes Minetest's time to shine.

Yes! I've been waiting for this forever. The first time I ran Minetest on a crappy laptop years ago it was as smooth as butter and I couldn't help but think, "Why is no one playing this?!"

I think the primary reason very few people play Minetest is because of marketing and piss poor default gameplay. If you just run Minetest without adding any of the (nearly built-in) mods you'll get an odd-looking Minecraft-like world stuck in "creative mode" (which is boring). If, however, you take the time (lots of time) to fiddle around with it and put together a collection of decent mods it becomes a good game!

The fact that it is written in C and has a proper modding API (in Lua!) should be drawing people in like crazy but for some reason it isn't.
I'm pretty intrigued by anyone who can honestly perform on 4-5 hours of sleep, night after night after night.

To what do you attribute this ability? Have you always been a short-sleeper? Is it something you've worked toward? Is age a factor? Diet?
Of course no two persons are exactly the same, so your statement about gain/loss is true no matter what. However, I just want to say that a wide margin is only about ~10%, or two tablespoons of peanut butter for a typical "doing nothing" metabolism. This is assuming roughly the same physique and exercise pattern [1]. People differ, but in my experience the influence of genes is overestimated quite often.

Of course, top athletes can burn through 2-3 times what a desk-worker might burn through. And I think the small number I mentioned above also tells that you can slowly but steadily put on quite some weight, by eating every day just one slice of bread more than you need.

The only sane answer is "Don't to put any roadblocks between them and catching up." or in a more positive spin, "Make available, without constraint, any resources they would need to catch up."

And it really does come down to morality, social and personal.

I am certainly in the "teach a person to fish" category of fixing societal ills. But I get it when previous choices have left someone "stuck" and unable to succeed.

Back in the early 2000's before we had all sorts of data[1] to back it up, I could see that single parents were in a world of hurt. Married couples had a much better shot at getting by. But you couldn't really fix that by demanding people find some soul mate/life partner to marry in order to get out of poverty. I suggested to my representatives and others we really could use an institution that had the same benefits of marriage but was more contractual than spiritual. If two single parents, regardless of sex, could enter into a contract to work together to raise their children, it would encourage them to do so. And by institution I mean the whole thing, rights of survivorship, community property, shared health care information, joint filing status with respect to taxation.

In my way of thinking that is removing a structural roadblock in the way of those people stuck in poverty by their past choices.

At the same time, I have also met people who don't put any investment into getting out of their circumstances. I realized there can be a learned helplessness element here, but for folks who just don't want to, I don't feel any guilt or remorse for them as they slide down the slope.

On the python side, this matches my experiences with python. Python is a great language, and I like it very, very much. However, packaging and deployment in python remains such an amazing mess, even after 20 years.

And outside of scientific computing, python doesn't offer any real edge, to me at least. Ruby has better tooling libraries, java/go/c++ have better performance, JS has more powerful website frameworks.

Why should I bother with that packaging mess after having it done once already?

Of course we don't have that information. If Oculus had not been bought by Facebook, it could have been bought by anyone include shudder Disney. Who knows.

Ask HN: A Job or a helping hand? Some advice?
I have never reached out for help but HN is at times life changing so I thought I would give it a shot. I figure the worst that could happen is nothing at all.

The situation. I'm 25, I have less than $100, live at home (in Idaho which has made things harder), likely on the autism spectrum and I struggle with depression + anxiety. I have about $8K in debt which is not a lot when compared to potential earning power but a lot when compared to my current savings. I spent 5 years living as a shut-in (long story you can read at http://fighttheurgetofade.com/). Started to work on getting my life back 3 years ago, it has been much much harder than I thought it would be; making money, dealing with mental health, and learning social skills is hard.

Never had a salary or a stable income. I have spent my career freelancing. At times I have had more than enough money to get on my feet and start living but a combination of poor decisions, bad luck, and mental health caused failure -- same story of everyone in a bad situation. I'm ready to get my life together but that first step can be daunting when you have so little to start from.

I'm a decent developer. I have a strong grasp of Ruby and JS (especially ES6, Redux and React). I'm a polyglot and have dabbled with many many other languages (lots of free time).

I would love a stable job to get my life on track.

Since the feature (as far as I know) started with Safari, some Apple-centric sites were early adopters, so sites like macrumors and appleinsider have it. But as far as more mainstream, one I know of is CNN, which has it for breaking news.

Not all of us want that. In fact many of us would rather decide for ourselves whether or not to play an animation, sound or not.

> This is what makes your argument moot - because they do gimbal, and the gimbaling is what creates the moment/torque. In a way that is very nearly analogous to twisting your hand around slightly to balance a broomstick.

The point of the inverted pendulum problem is that the torque on a long, thin, ground-supported object (or even just any ground-supported object with a narrow base or a hinge on its bottom) is a function of its orientation. That gives you a second order differential equation for tilt. This is NOT the case with the free-flying rocket because the engine is rotating along with the rocket. You could simulate the inverted pendulum actively, by rotating the engine so that it has a fixed orientation relative to the ground (up to the gimbaling limit, which is usually <10 degrees), but you actually want to do the opposite with the landing rocket (with significant damping to boot). Basically, you want the active control system to simulate a normal pendulum, just turned upside down (but with the damping so that it doesn't actually oscillate).

> The rocket is unstable in position and inclination (attitude).

Not the latter unless you make it behave in that way. You could also check on the Apollo LM landing guidance, maybe it will become more clear if you study that.

> So you're right that there's more to it, but it's still the inverted pendulum problem for attitude

No, it's not. That's the point.

> Are you saying Bezos is lying in this post when he explicitly says "When you do a vertical landing, you’re solving the classic inverted pendulum problem"? He would know, and I don't see a reason for him to lie about it.

No, I'm saying that this phrasing makes no sense. Remember that Goddard made a similar mistake when reasoning about rockets and pendulums, so arguments to authority are demonstrably to be avoided here. A significant clarification on his part could make it more comprehensible what he actually meant, but making any kind of analogy to a ground-supported object is clearly bad when talking about a free-flying body.
I usually don't comment on these posts, but I felt the need to in this one. A couple of things stood out:

- Python 2.4? Really? In 2014?

- Yes, writing compatible code with a 10+ year old release of Python is going to be hard. Who uses 2.4 still? You have to use the lowest common denominator, I mean I don't think Python 2.4 even supports context managers!

- Yes, in 2014 you should be supporting Python 3, or at least have it on your roadmap.

- The ethernet address (MAC?) via uuid.get_node(). Or for something a bit more advanced you can use netifaces[1] (or even better psutil.net_if_addrs[3]). One of Pythons core strengths is the number and variety of the packages available. Took 2 seconds of googling to find a cross platform solution.

- Calling C from Python is really really simple. Use the built in ctypes library, or something better like cffi[2]

I'm obviously firmly in the Python camp so perhaps I'm a bit biased, but I don't see any clearcut reason to switch other than "the current code is not optimal, let's re-write it in X", where X could be anything. I would actually say Go would be a much better fit than Lua in this situation. I guess the memory reduction/CPU usage is a point, but really your program seems to be network orientated. What's wrong with asyncio? How is replacing everything with a C library actually better?

What do we do about censorship? When countries block all foreign HTTPS?

It really feels like websites should know what transport they're operating on (secure vs unsecure) and present what information they can reasonably with unsecure. Though turning every website into a "modal" thing is also a pretty high order.
Google supports multi-user login. There are some annoyances with it, but it works pretty well for me.
Should I Leave Lead SE in Canadian Startup for Amazon SDE-1 in US?
I've been lead software engineer for 6 months (I'm also the first employee they have now, like a founding member). I'm also responsible for regular development management (e.g. sprint planning, executions). The current CTO is not as good as me (from my point of view) and I'm afraid he will be a blocker of the company growth and my career growth in the future.
If I leave for Amazon, I'll start from entry level and cannot gain any management experience in at least 3 years.
Another main reason behind is that this is one of few opportunities I could get sponsored for H1B and move to US. Since the Canadian economics is declining, I'm wondering maybe its better to move to US now, which may even helpful if I ever want to start my own business later.

Factor analysis can sometimes help by removing human biases in the feature / covariate creation stage. If you can devise a statistical process that reliably identifies which features are important, most would tend to agree that is better than relying on human intuition or first-principles from some domain science field to simply assert what they are.

But once you've constructed the features via that statistical process, and you plan to just dump them onto the RHS of a regression formulation, then it's no better. The same kinds of non-linearities can creep in whether you manually computed a human-level-description of a factor, or you let a statistical decomposition pop the factor out automatically.

The main point is that you cannot use most of the success metrics from a frequentist regression for the model selection and policy selection outcomes that most people want to use them for. Theoretically, it is just unsound. You have to dig deeper into the data, look at conditional views of your data, and try to use model fitting procedures that are provably robust to these kinds of artifacts, multicollinearity, and so forth.

I think the biggest problem is that non-statistician practitioners who work under tight deadlines in a domain science field tend to just want some kind of cookbook system that "just works 100% of the time." But there simply is no such thing. There is no cookbook procedure for you to take a bunch of variables, dump them into some fitting procedure, and automatically get comparable, consistent results that report back relationships according to the pseudotheorems of the Achen paper.

We need for practitioners in fields like quant finance, quant marketing, chemical informatics, and so on, to stop mis-wanting a cookbook, and to instead embrace that to create robust and trustworthy research results, it simply has to be done slowly and with great care. It's a corner that you just cannot cut, and you have to stop wanting to cut it.
This is an excellent example of what NOT to do, right along with threatening FX traders who are reportedly shorting the RMB ( http://www.businessinsider.com/china-warns-yuan-shorts-2016-... ).

I can't see how China, with an estimated 3 Trillion in reserves, is going to dictate to the 11 Trillion FX market how it should move - apart from adopting a transparent and proactive approach that acknowledges all the problems and puts forth a coherent, verifiable plan for resolving them.

At a time when we should be reading articles about asset liquidation entities (ala US Savings and Loan crisis) and middle class spending incentive programs (ala Cars for Clunkers) - we're instead reading about jailing statisticians.

Facebook supports it, I believe. And maybe Gmail, though that one could be Chrome-only.
Yeah, the only real advantage of lua is that you can link your code into the binary, and that it's super lightweight. But you can still deploy a python binary with your code, so the only real reason for switching is, "I like lua, and I felt the need to make my team switch."

Not that I don't lua. It's like the best parts of javascript, mixed with some AWK and scheme, with all the crap removed. OTOH, from-1 indexing is evil.
