I have a Raspberry Pi setup as a NAS and media server (see http://www.naspberrypi.com/) and the first thing I did was download the Linux x64 version for my laptop and the ARM version for my NAS and I had them syncing in about 5 minutes. This is awesome. I'm going to ship another NASpberry Pi (along with an external hard drive that's already a clone of my existing backup drive) to my brother who lives on the other side of the country and completely replace my $100/year backup service with this.
Wow. I'm really impressed. Great work, Chris.
This is probably a good place to point out: The SpaceX flight software team is looking for skilled software engineers!

> could [Persona] take the place of 3rd party social sign in providers like Gigya & Janrain?

Ideally, yes. One button, any user. No mandatory centralized / trusted third parties.

> if Google, Facebook, etc provided Persona endpoints could I use them to login people to $work's website?

You can actually do that right now. Persona includes a temporary centralized fallback that lets it work for any user, at any domain, right now. The only constraint is that the domain either needs to support Persona (as per the article), or the user needs to be able to receive email at that domain.

> All we really need is a way to authenticate a user and associate them with a user ID in our local database.

Persona is a Very Good Fit for this use case. If you're already storing email addresses for your users, you can implement Persona without making a single schema change. It should take you about an hour to get a proof of concept working.

I gave a 30 minute talk (+15 minutes Q&A) about Persona at PyCon last month: http://pyvideo.org/video/1764/. You might find it helpful in understanding the what, why, and how. I'm also more than happy to help you out personally -- contact info is in my HN profile. Please reach out to me if you have any questions.
In addition to the main point of this article, it's interesting to see that people are building a career out of Facebook pages in a similar way to we saw with prominent Youtubers taking off.

Yes, I agree. But why call out something like this page? Surely there are more successful and profitable content farms.

Not justifying the behavior, just saying that this example is the 'little guy'.
No, it's really not. It's undefined behavior and the compiler is free to do absolutely whatever it wants.

The point is that compilers do some specific thing, regardless of the fact that the standards bodies say they're free to reboot your computer.

As long as all you care about is x86/x86_64/PowerPC (and probably ARM as well), then you can trust that the compiler is going to generate code which copies the first two bytes of x into the memory occupied by y.
True, it will also increase internal resistance. I'm more of a thermo guy, though, so I can't estimate the remainder.
I think I am extremely bad at matching clothes. If this website can really solve this problem for me, I would use it in a long run. So in short, I would try and if it works for me, I would continue using it. If the result is not too great, I won't.
In hindsight, I shouldn't have been so surprised to hear of groups farming likes for profit...

Are there any good articles that talk about this practice? Seems like that could be interesting...
I would like to note that the STEM gender gap is much lower among new immigrants students (particularly from Asia and Eastern Europe) than their US-born counterparts, at least anecdotally. And I think this biases me towards the non-negativity approach argued for in the article. Much of the data about lower STEM performance from females in the U.S. comes from 1970's and 1980's data, when females also took fewer courses advanced courses. By 2000, female high school students were taking calculus at the same rate as males, though still lagged behind in physics. [1]

Perceptions are generally not nuanced and often lag 10-15 years behind. If you take the interaction of gender and ethnicity into account, you actually see an interesting reversal at the 99th percentile for Asian Americans where there are where there are 1.37 F for every 1.25 M. There is another study that shows Asian females score higher on STEM subject exams when they had to write a short essay about being Asian prior to the exam, but scored lower when they had to write about being female. (I'll try to add the citation later when I find it.)

Overall, I think the macro strategy of making female role models more visible is an effective one, and may well pay off in the next decade or so. Another reasonable strategy may well involve immigration reform with a special eye towards people who have focused on STEM subjects. Perhaps extra H1B slots for techie females? (I haven't thought this one through yet, but it may be worth exploring.)

Side note: It is also interesting to note that there are a substantially higher percentage of female Iranian mathematicians, and some of those mathematicians have noted that some of this is due to the cultural perception that highly theoretical pursuits (including theoretical computer science and theoretical physics) are not "too masculine" and are less likely to be dissuaded from pursuing the field.

Intrinsics aren't really C; they work in a C-like syntax, but you're still doing the exact same thing as assembly: you still have to write out every instruction you want to use, so you're not really saving any effort compared to just skipping the middleman.

In return, you are stuck with an extremely ugly syntax and a much less functional preprocessor, with the added bonus of a compiler that mangles your code.

I am also in the same stage as you. At first, i m thinking of shared web host such as godaddy or 1and1, and then watch the traffic daily. If it spikes to the point that you need a VPS, then you upgrade immediately.

Not sure if this way would be doable for you. But to me, why waste fund on something that you never use if you can allocate your fund to something else (i.e business cards, SEO, marketing, etc)? i remember reading that before pinterests got big, they only have few hundreds or low thousands users for the first few months they were starting.

Please let me know your thoughts on this.

Thanks.
I only skimmed the article, so please correct me if I'm wrong, but doesn't the article mistake correlation for causation big time? Students were asked to choose a topic, what if students who choose to write about values just don't care about other people's opinion, and thus perform better at it?

What evidence is there to point to a causal relationship?

One click and it opens in my native mail app (or my Gmail account, if I so desire) and I know immediately if it's a who or a what that my message is going to, I don't need to worry about broken contact forms that may or may not be working, I don't need to beat stupid captchas, and everything makes sense.

I think the problem is within the supposed science field sudo science is getting more traction.

People who have done science degrees are coming out and still believing in forms of magic like organic, chiropractics, chemical free, anthropomorphizing animals etc.

It's a fine line, should we appease the masses and try and get more scientists or try and at least get the supposed scientists practising and believing in actual science.

> I think we should relax about the idea that most people post inaccurate facts when they're cheering science.

The absolute only good thing about this is that it fights fire with fire: that is, it uses tribalism to fight tribalism.

But that's all it is. Atheistic religiosity is still religiosity, and it's a problem whether or not magical woo is involved. It's the same kind of thing when people think that calling out a fallacy is some kind of argumentative coup d'etat.

Or let's bring this back to software and business. How exactly do you feel when your sales team drastically overpromises your engineering capabilities?

That's how I feel.
I don't know if the author realizes it, but he just "announced" his product over his blog. He just launched it.

It's pretty common to wrap a product launch into your blog, Joel Sposky did it with Trello (and continued to do it every post) and Jeff Atwood did it with discourse.
Which again, are not parts of the story which are claimed to have been stolen. I would be fine with using the broad category of film-making instead of just visual effects.
>There is no "good ignorance".

This can't be stated enough; (the following is anecdotal) the amount of blatantly incorrect information being spread through the use of what I dub 'feel good infographics' across the internet is astonishing. The viewer looks at something, feels good about what they've read and then shares it because it passed their own personal sentiment analysis.

It's kind of frightening because it sets the stage for all sorts of astroturfing and conditioning to spread; if anything we should look at the Boston Bomber/Reddit incident as evidence of this feel good propaganda. People were so eager to attach to the notion that they had 'caught the bastard' only for the truth to come out later that they had completely fingered the wrong guy.
> But where was the non-public information?

The fact that the Tweet's content was false was non-public information for a short time, just long enough to see the market begin a plunge. Obviously whoever posted the false Tweet knew it was false, and they could have exploited that fact (not to say anyone actually did this), while other people were reacting to it as though it were true.

> Where was the gaming?

See above, and use your head. A pump and dump always pivots on the fact that the perpetrator knows what he's saying is false.

> Without proof of those things all speculation about insider information is moot.

Feel free to change the subject. We have already established that this is a hypothetical discussion.

> It would have been proof of an instable system if either A) the market moved for some incomprehensible way or B) did not correct for obviously bad behavior.

What does stability have to do with it? The topic is exploitation of predictable market moves, not unpredictable ones. Obviously a hacker could (in principle) anticipate, and act on, a coming market drop on news of an attack on the White House.

> Precisely as we would expect in an efficient market.

According your thesis, insider trading is impossible because the market will magically adjust to differences in information. If this were true, the SEC wouldn't care about insider trading. The fact that the SEC does care, demonstrates that your position is wrong, and that the market can be gamed.

A market cannot be efficient unless everyone has access to the same information. This is how the efficient market hypothesis is defined. And again, the SEC does what it can to assure that people can't exploit non-public information. The reason? It undermines confidence in the market's fairness and would ultimately cause businesses to avoid equities as a funding source.
It wouldn't be PayPal: though because there's only one PayPal, having a scheme for it would make no sense.

Currently using Rackspace for my contact email. I plan on setting up an Amazon SES for sending.
The students were assigned to one of two groups. Each group was given the same list of values. One group was asked to write about the one most important to them. The other group (the control group) was asked to write about the least important one to them and why someone else might find it important.

They were asked to choose a value, not a topic.
The name also confused me and I thought it would just be for tracing WebGL.

From a developer standpoint it's cool that it's in WebGL. As a developer-user I don't care, it just works well and fast!

I would genuinely suggest de-emphasizing the WebGL except in a behind-the-scenes way.

(I've bought and played with it, and can't wait to chase down a bug!)
I doubt that is true. The overall market moved less than 1% and I don't think individual names moved much more than their normal daily trading ranges.
So it's a kind of prettier version of the contact forms I've been seeing for a decade?
Ah, thanks for the clarification. The wording makes it sound like they got to choose both.
Not railing on these guys and in fact saluting them for taking a risk and for aiming to disrupt a well-entrenched "industry".

But, I do believe their money (however little it was) could've been better spent addressing the legitimate concerns you raise more directly and communicating why one with serious legal issues should consider their service.

I think that people do have a hard time trying to figure out how to locate and retain an attorney, etc. Anyone who has ever needed one can relate. So, connecting with that could have immediate appeal to someone who's been there or may well be there now (i.e. their audience). The rest of it was a bit distracting from that very important message.

Anyway, good luck to the Lawdingo founder(s) and team.

As someone who studied psychology before coming to tech, this phenomenon is fairly well documented. If you want, you can have a look here:

I think it matches up well with what was discussed in this blog post.
uint8_t foo[4]; *(uint32_t*)foo = 0;

Besides even without strict aliasing, the above is not at all guaranteed to work since not all architectures support unaligned loads.

So, the interesting thing about this example is that it does work. It's in fact very, very difficult to find a platform where that example won't work (i.e. crashes the program). For example, any C library involving image manipulation is likely going to have code similar to what you've described, and those libraries work on almost every platform.

Standards are a good and useful thing. All I'm saying is that it's important to know which rules you can safely violate.

> It is hard to believe that a significant percentage of pay gap between sexes is determined by negotiation skills

Don't shortchange the effects of compounding on those negotiations. Most raises of BOTH sexes are percentage based. But those percentages apply ALSO to the past gravy earned by negotiation. So 4k extra at 24 turns into 4,000 *(1.04)^26 (a hair over 11k) at age 50 from just negotiating that ONE time. And that's PER YEAR. And that doesn't take into effect FURTHER negotiations.

Now that's not to say it's the WHOLE story, but teach your children of both sexes to negotiate

On top of what raganwald said, the difference between IFLS and Reddit is that this is a curated stream done by one person, rather than an aggregation of user-generated content.

Reddit is morally different, since arguably you cannot hold them directly responsible for content generated by their users, they are strictly a conduit.

Similarly, we don't blame Facebook when their users post pirated content, we rightly blame the individual who pirated it in the first place.

You're right though, this isn't different than a curated stream of pirated content (e.g., many other Facebook groups), but as raganwald said, the fact that we can't catch them all doesn't mean it's wrong to catch one.
Counsyl Is Pioneering A New Bioinformatics Wave
A project I'm currently involved with suffers from a few things... 1) the unknowns never end as teh client keeps changing the freaking requirements! 2) they don't like our estimates and keep asking us to find another implementation to meet their requirements that requires less time and 3) they basically are trying to get us to implement the various solutions while "estimating", so basically we are doing the actual work while "estimating"... the estimate is suppose to be used for determining how much and how the development is to be paid... so we are burning non-billable time estimating (doing "the work") in order to shorten the estimated billable implementation effort. So the calendar date of delivery really isn't changing but how much is going to get billed is decreasing. And, if we try after doing the work "estimating" to say the amount of billable hours is more than the time to now deliver, they're going to say that can't be. Then we'll either have to dig our heels in and saw we did billable work while estimating or not collect on billable effort. It's so messed up. If I was in charge, I'd have fired the customer by now.
It's a nice idea, ESPECIALLY for social sites that focus on community. There's a lot of knobs that need to be tweaked to communicate the message and identify the true audience. But be aware what you give up when you sacrifice the big launch - a lot of nice links, some press, and a lot of tech people giving you a sniff.

If you think about it, the "big launch" is at direct odds with the lean startup approach.
Instead of implementing the whole of jQuery core, they could just add some of the features. It seems like that's already being done though (e.g. Element.querySelector()).

Javascript MOD player
I can't see myself using this as a service for casual wear, or even office wear.

In line with BobbyH's point 2 - I'd suggest looking into formalwear and weddings markets. In the "not wearing a white/ivory/champagne gown", it's really hard to find a way to match gown, hair accessories, shoes, bags etc, and then add in bridesmaids.

If you can find a way to select matching gowns - that would be hugely popular in both wedding and formalwear markets (going to prom with your besties with gowns that look awesome together I'd bet would get people in the door to your service, and if you can convert that to loyalty...)

Weddings and formal events are times when people spend more than they otherwise might on matching clothes and accessories, and for many will be the only occasions where they'd indulge themselves in a completely new outfit from head to toe.
