The problem is that, without an adequate foundation, he's jumping into frameworks and web development, where you have lots of interacting parts, all of which must be understood.

He's jumping directly from toy examples for someone learning a language to "industrial scale" development of e.g. full-blown web applications.

My suggestion would be to try to come up with a project which stays within the bounds of a single technology and doesn't require frameworks.

This will probably mean something that's not web-based.
I'm incapable of playing something like this without laying out some strategic principles:

When launching, hover the bird at the edge of the atmosphere for a few clicks, to give it time to tilt into horizontal orientation, so your thrust can affect the orbital parameters. If you don't do this, you'll just thrust vertically into the outer barrier.

Circular orbits are best. Two objects in circular orbits at different altitudes can never collide.

High-altitude orbits are best, where there's more room for more objects.

So circular high-altitude is best, but it's not easy to get there. Standard orbital astromechanics apply: to circularize, thrust at apogee to raise your perigee. Problem is, it's not easy to tell when the bird is at apogee, and it may not even occur before you lose control of the bird and the next appears. Also, the thrusting resolution is rather coarse: if the apogee is any higher than about halfway to the edge, two clicks will send the bird into the barrier, so you only get one attempt. These details and coarse controls make the game a lot harder than it looks, just like the original Flappy.

Finally, if you just need that one more point to break your high score, launch the next bird into the lowest fastest orbit possible. That altitude should be clear if you launched all the other birds higher, and it will register quickly before any more collide. I managed 8 thanks to this.
Nice work! We'd love to share improvements, as we're largely focused on Bitcoin but want to make Bitcore as simple to use as possible.
Thanks a lot for the interest. Unfortunately, as a team we are completely new to the industry, thinking about building a network from scratch. We were trying to reach out to restaurants online. Do you think is that possible or meeting in real life is a must for this project?
You sound like you haven't done much development before. Why iOS and RoR? Because they are popular? Anyway 128gb should be just fine if all you're doing is development. Also why get an SSD if you don't have a use case for it? You can get a 500gb disk drive much cheaper than ssd. Just because ssd and ios and ror and whatnot are current buzzwords doesn't mean it's the best thing for every case

Then in regards to time and effort invested, I would say many of the very critical parties I've met are doing it right. Scientist by-and-large are doing it wrong, in my opinion. There are parties still upheld by the climate debate which still refuse to share the data and methods they used to declare their findings. I don't care which side of the fence you're on, that's bullshit and can only be evidence of manipulation.
Funny you mention the Newton's Laws of Motion, that's the most famous theory demonstrated to be totally wrong.

It was a very good guess though.
Does that mean around 1 out of 2 Americans doesn't believe in evolution? That's scary.
Show HN:  Flatchy Bird – An HTML5 Flappy Bird Tribute/Parody
flatchybird.com

Hopefully HN isn't too beneath a little fart humor from time to time. We may be a little immature at Curious Media, but we have a lot of fun! Our initial goal was two days, but its looking a little more like 3.5 days at this point for the web version. We thought a farting bird would be pretty funny. We repurposed some of the artwork from another one of our games to save a little time and built it using ImpactJS. There is a leader board that records your best score. There are still some minor bugs and such, but overall it should be fairly playable on desktops, tablets and mobile devices. We haven't really tested it on legacy devices yet. What do you think?
This is unnecessary - it's functionally equivalent to just waiting a moment before launching for the orbiting birds to progress. There's nothing absolute about the positioning of the launching bird, it's all only relative to the orbiting birds.
I'm the founder of an edTech where we are using software to _IMPROVE_ teacher training. Teachers, especially new teachers, need a lot of support, not just from in school peers, but outside of school. They also need constructive feedback on their practice (from peer teachers, parents, and students). Current training is one size fits all and not personalized. Current evaluation only focuses on test scores.
Because you have been tested. The term "guess" implies lack of good grounding.
Technically, both objects are orbiting their barycenter, or center of mass. For the Sun and Earth, that barycenter is very near the center of the Sun, so in common parlance most people will refer to the Earth as orbiting the Sun.

Perhaps asking whether "the planets" orbit the Sun would lower the chance of ambiguity.
If he is classifying them as male and female and treating them as such, then both parts involve gender.

The first half involves judging people by appearance; unless he's running DNA tests, ultrasounds, and fondling everybody he meets before he uses a pronoun, then he his judging at least partly by how they present. That's gender.

The latter half, how he treats people based on his gender-presentation-mediated perceptions of sex, is pure gender, because there we're entirely out of the realm of biology and clearly into the social side of gender roles.

I understand why he (and apparently you) would like it to be simpler. It's more convenient for him if everybody goes around hiding the complexity for him so he doesn't have to have a more accurate view of the world. But it's bunk. Pretending that it's "just" sex he's talking about is part of the way he hides, presumably also from himself, that it's bunk.
If it's not too personal, I'm curious to know what you get out of the relationship.
Things have changed a fair bit since I was in college (1994-1998).

A lot more of computer programming is higher-status, more marketing-driven and more about money.

You're seeing proportionally more frat guys interested now.
I think the thing that is most often missing from educational software (and most online course delivery formats) is the most important thing: motivation.

The teachers that I most fondly remember weren't the ones that taught me the most material, or ensured that I got the highest test scores. They were the teachers who inspired me; the ones who unlocked a deep curiosity and desire for learning inside me.

The current system doesn't care that much about motivation (although it is changing). You take classes largely because you have to. You learn so that you can pass a test.

Openness in teaching is a big piece of the puzzle, but it isn't the end of the road. In software, for example, I would argue that by becoming more open, motivation to improve was increased among developers (I don't want to be the one with the terrible code on Github). Of course, in software, the target of openness and the one who needs to be motivated are the same person; you. This isn't the same in education. Increasing openness among teachers will undoubtedly have an effect, but the customer for education isn't the teacher.

We are essentially circling the problem by saying "students aren't learning, let's change things around with the teachers." I think that teachers are very important, and I definitely don't advocate mass firings. I just really hope that we find a way to rephrase the goal to something more along the lines of "students aren't learning, how can we work with the student?" If this is teaching basic stuff largely through online methods and having teachers spend more time with students, great. If this is increasing transparency surrounding schools, great. Personally, I hope that some combination of better software that automates basic stuff and allows teachers to work one on one with students more often, more information, and more training will do it.
App to help you write short, declarative sentences
My takeaway was that the OP could not grasp MVC which caused all the issues with learning the frameworks. Also I'm a firm believer that you can't really learn unless you want to make something. If you're not trying to build a game/website/app that you're excited about then you're not going to go far.
I have to agree that the baby looks frightening. The web site would be stronger without that image.

Of course, adoring parents who are addled from sleep deprivation would love this service, I suggest you replace it with a drop-dead gorgeous baby painting.
But we already have $hit for currency--the US dollar. Ben Bernake is pinching off $2.793B/day. Compared with the US dollar, cow pies have actual intrinsic value:

1. You can burn them to make heat or electricity. By contrast, it is illegal to burn US bank notes: http://www.law.cornell.edu/uscode/text/18/333

2. Burned cow dung repels mosquitos. By contrast, US dollars attract blood-sucking bankers.

3. Cow pies used in building materials are a cheap thermal insulator. By contrast "cold cash" and "hot money" are just metaphors.

4. Cowpats are a fertilizer and may be used to produce agricultural commodities. It may be true that "Money begets money" (or M-M'). But US currency can't produce real goods or services that people want unless its invested wisely, and right now the US is printing money to blow housing bubbles.
We have now gone down the rabbit hole.

It is nice down here.
As a counterpoint, I run web forums and at times have encountered trolls. When they've been banned (at the behest of the vast majority of the community) some of them have made me their target.

Aside from death threats (which I dismiss as joking), I've been signed up to hundreds of porn and adult mailing lists and sites, I've had reports of my photo and vague details being used on lots of "m4m" casual sex adverts, and I've had the "here's a streetview of where you live, we know where you live" type intimidation.

I'm really glad that the efforts of a few trolls doesn't really show on Google because my name is fairly common and there are some people who share the name who have achieved some fame or popularity. The result of the top-ranking stuff means the work of the trolls is nowhere to be seen.

If I had a unique name I've no doubt that it would have been trashed thanks to other people.

My point is simply: You may think you are in control of your online identity, but you are not.
I was busy writing a comment while you cranked this out, so I'll just reply underneath yours since we more or less agree.

The premise of the article is a valid one but the arguments underneath are incredibly weak.

Perhaps a question on how Dropbox might be used to solve income inequality or the unaffordability of housing in San Francisco would reveal as much about someone’s creativity—and more about their character—than questions about superheroes

Certainly a refined hiring protocol that asks targeted and direct questions that allows the candidate to express and communicate their competence may perhaps improve the metrics of gender-diverse hiring. Suggesting such a radical change like asking for an opine on economic disparity at a Cloud Services Provider however I think is going a bit too far just to step back and claim progress; Post hoc ergo propter hoc

The author here seem to stumble across, and then walk right by a much more interesting story in the use of demonstrably masculine conference room names in which to conduct interviews. All we got out of that was one paragraph.

Why is that scary? If we assume it is indeed a matter of belief the 50/50 chance is not that bad. Now, I suppose both you and me think about it more as a matter of science, but how many people understand what science is (and why), how the scientific method is applied and so on? Well fewer than 50%, I'd guess. US, Europe or Africa, any place.

IME, that's because most people haven't ever heard any reasonable explanation of evolution. They honestly believe that evolution is just "random things happened and fish decided to walk on land". That "animals wanted to see so they randomly got eyes". Given that explanation of evolution of course they're going to reject it - that explanation is nonsense.

Creation is only simpler if you exclude the axiom of having some omnipotent creator in the first place.
This is the part that gets me. In my life I can think of 3 instances of cars catching on fire that I witnessed personally. One was a neighbor who's suv caught on fire in their garage and burned their house down. I dont even remember what brand the car was but with Tesla it's headline news worthy.

The sound of space has been recorded for the first time
Yes the relativistic model is more accurate but like any physics it is still a model and only an approximation.

The newtonian / euclidian model is going to be accurate enough for most people (and some space missions) + its much simpler to compute and also it lies closer to human 'common sense' making it a lot easier for people to grasp and think about intuitively.
The OP is trying to argue that there's a preferred frame of reference in a physical theory (relativity) that explicitly disallows preferred frames of reference. If you took a position roughly 200 million miles (about 320 million kilometers) above the sun's north pole, and watched from there, you would certainly see the earth orbit the sun. The reason? Different curvature from that perspective.

The OP could have simply said that, in relativity, there's no force called gravity, instead planets orbit their parent bodies because of curved four-dimensional spacetime. He then could have quoted physicist John Wheeler, who famously said, "Matter tells space how to curve, and space tells matter how to move."

After the OP correctly said that the earth is moving through curved spacetime in a straight line, IMHO he should have turned in his golf clubs.

> Your comment feels far too clever for it's own good.

You got that exactly right. The OP's intention is to confuse, not enlighten.
The AttributeError is in a different category, because the interpreter protects you from doing unsafe things, and you get a clue as to what is wrong because you get the name of an attribute and the object which was supposed to have it. Segmentation faults can be much more difficult. For example the other day I got a segmentation fault deep in the CPython code; there was no bug there, and moving up the stack trace also did not reveal a bug either. It turned out that I had messed up a reference count _in a completely different (Cython compiled) module_, and I only found out after poring over several sections of code repeatedly.

The reason that this can happen in C is actually exactly what you bring up, silently corrupting memory. It's just that with the segmentation fault the silence is broken abruptly.
Damn dude that's pretty depressing. Maybe her boyfriend was just PLAYING ONLINE GAMES?? I mean the point of most games is to virtually kill other players, playing some pranks seems pretty mild in comparison
Yeah, but how many people conducting surveys are actually practicing this level of scientific rigor? Unless a study specifically points out what they did to ensure the validity of their results, I assumed none of these additional checks were performed.
They do have the sources under http://www.red-lang.org/p/download.html
sigh ...take a moment to re-read what I wrote. Then take a moment to re-read what you wrote.

Newton's LAWS of Motion are not a THEORY. They are a descriptive generalization about how gravitation behaves under stated circumstances. Those circumstances being slow speeds and large masses. In those circumstances, they are not wrong. They are a generalization. The THEORY of General Relativity contains Newton's LAWS of motion as a part of the overall framework.
Getting effective sampling in case-control studies when it comes to the structure they seem to have put together is complex, with pitfalls. With the numbers they have and descriptions provided, we have little reason to believe this study was structured this way, let alone in a useful manner.

Knocking down the paywall would help, but most pop-study coverage usually is great for research funding, but not often an indicator of great research. I did a case-control study showing this at some point and it got published to an open journal somewhere.
Good luck guys! At Spreedly we have the same type of approach for FinTech startups by removing all the PCI compliance headaches. Perhaps one day there'll be a fit to work together. I imagine startups will love you if you pull this off!
It is too clever, by half. From my perspective it's a long-winded and self-contradictory (as you note) attempt at punning with curvature tensors and metrics, only not doing it right.
True, and this would work, but why would you favor this over Promises? They're an open, well-known spec with a lot of implementations - hell, some browsers support them natively. Promises also offer better control over sequential action and error handling.

My advice on web frameworks: Try to make a project without one. If you're where the author is -- tolerably familiar with HTML, CSS, and JS -- look up WSGI or CGI. Write a program that outputs HTML by string manipulation.

Try to build something simple, like a web forum, or maybe one of those old-fashioned "guestbooks".

Then you will be able to see the pain points that a web framework solves. For example, you'll eventually decide you want to save your forum posts to disk to make them permanent. You make some format which you can just use read() and write().

If you've gone through the pain of doing this, when you go on to read about databases, you won't say "WTF this is overwhelming and irrelevant," you'll say "AHA this makes so much sense -- I know exactly what problem this is trying to solve -- because I've already spent dozens of hours solving that exact problem!"

MVC got you down? Well, if you started out with a basic web forum software that only allowed login, posting, and viewing, then updated it to include user profiles and avatars, my guess is that when writing the update you would have encountered frustrations due to poorly organized code. So when you later read about MVC, you say "AHA! I understand exactly what this is for -- because when I had to make major changes to a codebase that was already fairly large and complex, I had lots of pain, and came up with a laundry-list of ways new code should be better-organized to avoid similar pain in the future -- and MVC looks awfully similar to that list!"
It's not exactly clear what you mean, or you need to be more specific: a curriculum is curated content.

Good curriculums are covering over a lot of poor teaching.

Writing a good curriculum is hard and it's exceptionally difficult to do that as a lone teacher for a novel course. The results will be variable, and this is where you will the very most awful courses.
> This results in that the location of the earth doesn't change, but as the sun is sucking in space and constantly pushing out it's matter the distance doesn't change.

This is just one of many egregious errors the OP makes, scattered alongside a few obviously misunderstood elements of real physics. I advise HN readers to ignore the OP's post.
Wise words of wisdom from kimjotki2, the only real programmer on the internet. Bow down, bitches.
To your second point, I wouldn't test only reading levels - I'd test whatever we want/expect students to improve in. Reading, writing, math, social skills, happiness, physical fitness, whatever. And sure, we need good solid methods for testing these things, so let's get started on it.

To your first point...maybe 30 kids isn't a big enough sample. I'm not suggesting this be implemented tomorrow as the absolute standard on which to judge teachers. Maybe they need to be observed over 3-5 years, maybe we can try to control/adjust for other variables. What bothers me is the idea that because measuring teacher skill/success is difficult, we shouldn't try at all and just use seniority (or absolute test scores) as the single deciding factor.
People that operate outside of coherent, explainable, rational principles tempered by compassion are bigger liabilities. It's common sense.

Departing from this is what allows folks to believe violent terrorism to be a viable strategy to "win."

Such persistence, much currency. Wow.
Holy crap. An article with the words "cites research", with a hyperlink which actually goes to a PDF of the actual research being cited!

Would love to see HN rise to the occasion by discussing actual facts and data, rather than spouting opinion and speculation. (A popular pastime, to be sure, but it's always nice to do something different for a change.)
> It's interesting, because I find more pleasure sometimes in rereading a book or watching a film again than the first time [...] So I'd say go ahead and enjoy reading about things beforehand, you may well find it actually improves the experience

That's lovely for you. You are not me. You are basically doing this:

me: "I don't like artichokes."

you: "Oh, that can't be true! You must never have actually eaten artichokes! Surely you are laboring under a tragic and inexplicable delusion! Here, hold still while I stuff artichokes down your throat! You'll thank me later!"

Yes, thank you, I have had artichokes. I have never enjoyed a work of fiction more for having pivotal plot details spoiled, and I have often enjoyed it less. I am quite capable of evaluating my own reactions to things, thank you very much. You are not doing a public service by telling everybody to just be more like you.
