startups make money by making people behave differently - paying them instead of someone else. that's changing the world.

let's stop pretending there is more to it than that, because it's hard enough.

Remember to ensure that your build strategy is set on all associations if you want this to work, e.g.

FactoryGirl.define do
factory :user do
association :account, :strategy => :build
end
end

Otherwise when you build a user, the account association will still get persisted to the database.

Even if you do this, though, you're still spinning up a whole network of real objects in what is supposed to be a unit test.
I think you are describing the situation in America, where i 'm not. I am wholly against drug use on philosophical grounds, but i would assume that their production would be easier today than it was in the past. I mean, we have personal PCR machines, i would assume the mechanics of drugmaking would have evolved since the 70s (no Moore's law there?)
Reading Steve Job's biography right now, and it was really surprising to me how little (almost insignificant) of a role Woz played at Apple after the first couple years there.
I'm reading that as more of a marketing/concept line. I'm pretty sure that if you'd walk into their offices they'd all still got keyboard/mouse combos still.
Even a growing company (like PopCap) can still have a layoff be a good idea for business. Their main reason they cite is that the business model is changing. This is phenomenally important.

If Kodak had laid off three-quarters of its film staff and hired like crazy to get into the digital business back before digital cameras were a hit, they would have been crucified by the city of Rochester and in the court of public opinion. In hindsight, though, it would have been a smart decision and one that could have saved the company.

If your people can't adapt to the market, you need to change your people. It's an unfortunate reality, and it sucks for all involved, but good businesses make hard decisions like this. I hope things work out for PopCap, and my heart goes out to those laid off--life is about to really suck for them.

SEO spam on Hacker News?
I try to visit semi-regularly the Newest page on Hacker News, and always see obviously non-HN material posted (some in Portuguese, Russian and other languages, other are porn). Are those SEO spam? Do they get some benefit from posting here? They're always dead by the time I see them, and the links are removed.
I don't think you know nearly enough to make that claim. You don't know what value each party is bringing, or their roles, and you don't know how much was done before OP joined. You don't know if the business has any particular strengths.

Assuming significant work was done before OP joined, equal equity is not realistic (or fair). Also, are the others taking any money out (i'm guessing not?). There can of course be some value in ideas and traction (although AFAICT there isn't a lot unique nor is there a lot of traction). Moreover, i'm guessing most big decisions are not made by OP since he seems to be relegated to employee. Only if OP feels they are crucial and replaceable should he go for 1/3 (or more). From the little i know, 20%+ would be a good aim. If you think you can do better elsewhere (that is, you don't believe the business has unique strengths) then consider that.
Because it only includes the minified code.
In the time of Newton, there were numerous smart people trying to explain how gravity works. Newton's tremendous insight was that if he could develop a mathematical model that accurately predicted the movement of objects under the influence of gravity, it would not matter whether he could explain "how" gravity works. It was the original "shut up and calculate" moment, and the birth of our modern conception of mathematical physics.

Science describes and predicts. Ultimately it cannot tell us "why"--or "should". These will always be the realm of philosophy and religion.

Where religious dogma contradicts proven scientific understanding, the religious dogma must yield. But I worry that in our zeal to resolve that conflict, scientifically-inclined people also end up attacking the sense of emotional awe that is at the heart of the religious experience. That's a shame because it is also at the heart of why many kids decide to go into science in the first place. Carl Sagan addressed this a bit in his book "Contact", in which he calls that emotional experience "the numinous".
And I'd upvote it to Mars. FactoryGirl is completely an anti-pattern, unless maybe you're doing acceptance testing, but you know even then I wouldn't want FactoryGirl in my codebase, people would be too damn tempted to use it everywhere.
"But people raised to believe that physicists are more reliable than Hindu priests will prefer molasses to milk. For those who cannot follow the mathematics, belief in the Higgs is an act of faith, not of rationality."

This reminds me of the episode of South Park where Cartman travels into the future to play Nintendo only to find a post-religious world mired in faith-based fighting.

If your quest for understanding takes you down the path of science or of religion or both, at some point you are going to have to take something on faith, and to succeed you will eventually have to defend that faith - usually against someone else's faith in something else.

We all have our cross to bear.

Whether or not it's a bad recipe isn't for me to say however I do struggle to understand the motivation VC's have when they invest millions into companies like lanyrd.com who publicly state (even many months after receiving funding) that they have no idea how they plan to monetise the company.

Huge userbase, no monetisation plan. I appreciate all investment is a risk but surely investing in a company who has no clue how to monetise is immensely risky?
I'm still in awe over this. Cheers to the engineers of the past, present and future who make this science fiction become reality.

There is also the inverse problem on some input interfaces. I do have to write emails, sms, weibos, HN comments in English, Chinese and French. I don't know how ios handle this issue but on you have to open a thing, tap, close, and it is not very convenient. I use Swype beta, which is actually good, but it is annoying to live in a world where monolingual is the norm.

I have no figure but I'd guess multilingual is actually the norm in many countries.

I have an iPhone jack in my car, I listen to the radio occasionally, it's nice to listen to something different and hear a bit of new music, re-discover some old songs rather than rehashing my usual playlists out over and over again... I don't think I would ever connect my iPhone and use it as a radio though. Aside from the battery drain (yes, I have a car charger, but think about when you're not in the car) I think it would get annoying listening to 30-40 seconds of a track and then flicking back to radio!
Obviously, it doesn't explain everything from your example, but Kongregate rewards users for voting for games (1 point per rating in their levelling scheme). This will have some impact on how people vote.
I was chatting to a friend about this the other day who felt the same way. He will have moments in his books that will come across as such powerful theologies and ideas that you will spend years thinking about it. The problem is for every mind blowing idea he explores, he has 15 chapters of the wordiest words I've ever worded. I'm reading Cryptonomicon and he spent 19 pages - 19 PAGES - describing a guy eating cereal. Combine that with the fact that he will frequently use words that I don't think anybody but him knows (The whole reason I bought a e-reader was so I can use the definition function to understand what the hell he is talking about) and it feels like I'm reading the literary equivalent of Dark Souls. I really love the ideas he writes about, I just wish he didn't have a burning hatred for the reader.
Congratulations to the Typesafe team. As a regular user of Scala, it is very welcome news to see the commercial arm succeed.

It's interesting to watch hybrid open-source/commercial enterprises develop. Getting the revenue stream right is tricky. I could really see the Typesafe Console growing to offer a whole host of monitoring around distributed computing. If Typesafe provided a wrapper around Hadoop that would be a welcome addition.
Complexity of Scala has been debated many times. Just because a language adds some new concepts and is different than other mainstream languages, is not enough to call it "complex".

Before you answer question about whether Scala is complex, try to answer the following questions first:

Is JEE complex?
Is Spring Framework complex?
Is Maven complex?
Are webservices complex?
Is C# complex?

They are, they introduce new concepts and in many ways they have much more rough edges than Scala (remember JEE 2.1?). Somehow all of them have been widely used in enterprise software development in many successful projects.

I'm surprised by how much flexibility Scala offers with so few simple concepts. Ok, you have to take some time to learn them. But this is the same as learning just any new API.
To be fair, comparing something like this:

(partition-by #(> % 60) [49 58 76 82 88 90])

to so-called line noise code seems reasonable enough. As with Perl, if you immediately know what all the punctuation means and what the underlying structure of the language is, it’s concise, but if you don’t, it’s quite a mess of random-looking symbols.

For comparison, here’s a Haskell version, which in this case has a more intuitive syntax, IMHO:

filter (>60) [49, 58, 76, 82, 88, 90]

And here’s a version in Scala, with a more explicit function value:

List(49, 58, 76, 82, 88, 90).filter(n => n > 60)
well... i'd say nothing is worth over-working yourself. i like my sleep very much.
Wow! I was looking for a way to block Facebook and this is the best way I can think of :)
A response from a naysayer:

Factories are slow.
Yes, they really are.
Persisting everything along a chain of associations will always be slower than properly isolating the dependencies of the unit under test, SSD or not. It's easier to enjoy Ruby when not constantly waiting minutes for tests to run.

Factories increase the over-all complexity of your app.
Are you kidding me? Yes, they do. Expertise and huge, easy gains have nothing to do with reducing complexity and more often (but not always) increase it. A test suite where every test depends on state in a database is more complex than one that tests units in isolation.

None of these points are arguing against Factory Girl, which is a great tool for doing what it does; they are arguing against integrating with the database in "unit" tests.
Other than the orange whats wrong with it? Funny how the good stuff on a site is always done when the site is simple and plain looking.

Sounds like a solid deal to me.

Science doesn't require you to take anything on faith, for every theory and result it states it gives you the tools and methods to go away and verify it for yourself. It might be a stretch to expect someone to build another LHC, but if they don't trust the science coming out of there they could build it for themselves and see.
Faith is the belief in or of something in the absence of proof, science not only provides the proof it makes it possible to prove for yourself. Science only requires trust in the scientists who are providing the results used to prove the theories.

Sorry, but I as one of those 50 million Paypal users will continue to refuse to do business using Paypal unless absolutely necessary for ease of use (sadly there still is no easier way to have people pay me for services besides PayPal from various other countries in the world).

I don't trust them with my money, and I certainly don't trust them to handle it correctly.
Belief is important in science. In science we only disprove a hypothesis (falsifiability). If we repeatedly fail to disprove it we begin to believe it true. Yet we can never rule out that one data the data may exist to disprove our strongly held hypothesis. We never prove it true we simply believe it true based on the continual failure of disproof.

Not really. The new hardware is selling itself already. The goal of Windows 8 is to ensure that Microsoft is still relevant in a world where that hardware dominates the computing marketplace.
The only way to master something is to use it again and again over a long period of time.

But if you are asking about getting started with a new language, then it will vary from person to person based on your mode of learning - some learn by reading, some by writing, some by coding, some by reflecting, and some learn by teaching. You need to figure out what your preferred mode of learning is and do that.

I learn by copying some other code. I'll find a small tutorial and follow along typing the code line by line. I dont copy-past, I actually type it out. I don't necessarily think about what I am typing, just following along. If its in a book, I'll type out some of the examples. After its working, then I'll find a different tutorial and type it out again. Usually after a few programs like this, I start to get the hang of the basics.

One quick suggestion. If this is for "normal people" (I'd rather have that say non-techies as it's slightly insulting to us non-normals), try to factor our programming terms. 'Version Control' is a programming term. I would change it to 'File History'.
I don't think so.

People will stop having offsprings (and even sex) well before that because they are immortal, even if they die, they can be resurrected because they have copies. Provided, human race doesn't get destroyed by itself or AI.

They are attack surfaces ... you can attack the engine through the gps.

Sure, but the "attack surface" of the engine management firmware itself isn't enlarged by the presence of an insecure GPS system, is it?

I don't know if the people developing engine management firmware think about fire-walling themselves off from the rest of the in-car network. Certainly, they should. If they do, then the size of the code in the rest of the car doesn't seem relevant in terms of securing the really important stuff.

I have the same gut reaction when I learn someone is religious/atheist. However, I after talking with most people what they say openly about religion vs what they say in private is often vary different. One of the most fascinating questions I think is 'how likely to do you think there is a universal creator?' Not based on what people say, but because it cuts though so much BS that people project.
I couldn't find anything to take away from this article (and now this guy can claim to be publishing in Nature? What a load of BS).

- Higgs was the goddamned particle, which was censored to 'god'. In any case it was just a joke

- In a sense scientists believe in science, because it has never failed them. As much as most would not admit it, i believe they see some metaphysical meaning in searching for nature's truths. Plus there is some (neuro-)science that deals with metaphysical/religious feelings itself.

- Just because certain places, thoughts and readings create certain chemical reactions in our brains that we perceive as deep mystical emotions doesn't mean they matter in themselves. I used to have a fear of locusts.

- a walk through the magnificent temples of Angkor offers a glimpse of the unknowable and the inexplicable beyond the world of our experience: Isn't it weakness to stop there and say "OMG"? What causes those feelings, what purpose do they serve, and why do they happen in that Temple? Why do we even have the word "unknowable"? I think that's why science is more fun

This guy needs to come out to himself as a theist
I would argue this public outcry should have been predicted and is not the kind of sentiment AT&T should be seeking from their customers.

They should be adding value to their existing services and getting customers to pay for that added value, not trying to find ways to charge their customers more for their existing service.

Apple releases new hardware on a regular schedule - never once has the price increased for a newer model of the hardware. With Apple, the quality only gets better as the price gets cheaper. With AT&T, every contract not only comes with a price hike, but with more restrictions.

I want to love AT&T - they were the first to carry the iPhone and they employ more than a few of my family members. But, under current leadership, I vote no confidence and have serious reservations about locking myself into 2 more years of these shenanigans.

Relative ratings are more useful. Everyone uses their own scale, but their ratings are relative to the constant movie. I want to see how people rated a movie relative to other movies I've watched.

N people rated this better than X movie, but less than Y movie.

Ranking movies can be easy. Show 5 movie posters instead of 5 stars or have an auto-complete field for this movie is up there with:.
Google Chromebooks get easier-to-use apps list
I'll meet you halfway. It's a terrible comment about a terrible article. I agree that it's laudable to try to invent an improved version of online ratings, but this article wasn't effective in convicing me that they've succeeded.

Their argument that historgrams are just.awful. (I didn't care for the extra periods) seems to have two components:
1. asserting that historgrams are bad
2. showing us 3 histograms and saying they tell you the same thing about all 3 movies, when in fact there is a very clear and important difference between the histograms.

Its completely obvious from inspection ("people are really good at seeing patterns") that Starship Troopers has a much lower percentage of 5 star ratings than the other two, and a much higher fraction of 0 star ratings. It also appears to me that the Fifth Element has a higher fraction of 4 or 5 star ratings, and is probably the most apprciated of the 3 films, although Blade Runner is fairly close.

If you are going to cherry a set of 3 specific films to make your point, you should be sure to at least pick 3 films that support your point instead of refuting it.

We then learn about their hypothesis that while 5-star rating system sucks, a system that relies on two correlated 5-star ratings is great. They demonstrate this by using the two question system to draw the exact same conclusion I drew from the histograms of the 1 question ratings.

I would've liked some sort of objective attempt to compare the two rating systems. Perhaps it would be possible to measure how frequently the two question system leads people to make a better choice than the one question system, or at least some sort of statistical wonkery that would purport to show me that the two question system in practice draws more distinctions than the one question system. Unfortunatley we only get this one rather uninspired example ("watch this if you’re in the mood for something really good").

They also didn't address why "would you re-watch this film" is a better choice than any other second question. There are attempts to justify it being a good question, but no real evidence that other questions were tried and didn't perform.

Finally, the thing that really irked me was that this proposed system doesn't seem to do anything to address most of the actual problems with the regular 5 star system, namely that people who feel really strongly about something are more likely to rate so that most ratings tend towards the extremes, and that without context we have no idea why someone rated something a 5 instead of a 1. Those problems now exist along two dimensions instead of one.

I see this less as an article and more as an advertisement hitching a ride on an xkcd comic.
