Man, tough crowd. I have a Lytro, and I love it. I'm quite a fan of the technology. It's not perfect, and it's uses are (for now) somewhat limited, but I feel your criticism of it may be a little overly harsh.

First off, the current Lytro model does not, and will not, replace any traditional camera I own. I like the technology, and it has it's uses even beyond demoing the refocusing abilities, but it's definitely a supplement to my camera arsenal and not a replacement for anything.

You're right that you can "simulate" focus-stacking with a traditional camera, as long as the object you're shooting is sitting still and there's no motion of the camera or in the frame at all. Any motion at all and your simulated focus stacking doesn't hold up well.

Likewise, you can get a perspective shift from multiple images by slight movement with a traditional camera. Assuming again that no actual motion happens and that no observable length of time transpires between the successive offset shots.

Since the Lytro doesn't have these time limitations, and since focus can be done after the fact, I've been able to get a couple of shots of events that I could never get with a traditional camera, just based on the ability to point the camera and snap the shutter without having to even wait for autofocus to happen.

The hardware in the camera to me feels far ahead of the software that drives it. One of the biggest criticisms I have of the Lytro is that the camera captures a vast amount of light field information, and through The Appropriate Application of Mathematics, you should really be able to do a lot more with the captured pictures than you can now. I remain hopeful that as the camera software progresses that more of these possibilities will come to light, and so far other than the time involved to develop the software I haven't been disappointed - there have been pretty regular software updates, and features are being incrementally added.

The Lytro isn't perfect - I'll grant you that - but it's a radical change in technology, and I think that over time the technology can only get better. The price for the current model is a little higher than "what the heck, I'll try one out" typically justifies.

One thing I use my camera for - more than the refocusability - is macro photography. The Lytro has an absolutely insane macro focus capability. It can focus right down to the front of the exterior lens, and it does a great job at shooting small objects at short range - better than any SLR macro lens I have, and I have a couple of "not cheap" ones to compare it to.
Everyone knows how to call up their ISP and ask for filtering to be turned on or off.

First step after buying a mobile phone is to call them up and get them to remove the stupid filtering.
Oh, good call. Thanks.
I am one of those people. I refuse to upgrade to iOS6 presently on my iPad2.

This was initially because of the maps degradation, but now I also don't see any reason to actually undertake the upgrade, apart from removing the little notification counter on the setting icon that for some reason I find annoying.
Love the mix of articles and the approach that this site takes.

Only if you're American. Netflix works in a number of other countries.
not sure i agree with you - Prime has a decent selection, but is organized in a very frustrating way compared with Netflix. While netflix bundles tv-show seasons, you find yourself adding season after season to your 'watch list' on prime (which they only recently implemented - before that you didn't even have a queue). Also, their Roku/PS3 apps are much more painful to navigate with repeated movies (the standard def version and HD version), fewer categories, and i've often had problems where the movie/show will cut out consistently. More or less if i can't find the show/movie on netflix i'll search prime, but other than that, prime is best for the 2-day shipping.
Hi guys great job on the technical aspects!

I feel like the emotional and film aspects are still slightly a leap. I didn't really feel much for the fisherman or the seagull, I was just banging away on my spacebar.

Outstanding job Marco. I'm impressed with what you've created here. This is a great way of showing the world the culture of Zaarly.
The camera's raw format is indeed an entire light field (I've used nrp's tools, they're great). The camera import software creates a layered JPEG out of the raw data for uploading and sharing, since the size and the amount of math involved in refocusing the raw image on the fly is significant.
And then there is the option mentioned in the article, where the spinning permanent magnet is not made of expensive rare-earth metals, but rather of a metal in which a magnetic field is induced by stationary windings.
Amazon's Jeff Bezos: The ultimate disrupter
Has the author considered that she's just playing devil's advocate?

I wish more people would consider the effect on clueless users when they implement something.

This bit, in particular:

>Jonny Shipp: If you talk to your Service Provider, they’ll help you, I think, mostly.

>Helen Goodman: How do you talk to them?

Is a valid point. Many people don't know who their internet provider is, nor how to talk to them. And, be honest here, how many people have had a useful experience when calling an ISP tech support?

She's trying to say that regular people cannot filter their own machines, and thus someone else (the government) needs to do it for them. But we should use that to say that she cannot understand why we cannot do it for them; that government sanctioned filtering will fail in many ways and be harmful; that the best thing to do is set up a quango and a help line and give away filtering software for PCs; (combine that with a malware scan and maybe the UK can reduce the ridiculous number of trijanned machines we have).

Having said all this, she actually is stupid and clueless, and in it's scary if she has any power over IT.
That would be useful. I think gerrymandering is still sort of abstract and inside baseball to a lot of people, but a stark visualization could make it a hell of a lot more immediate.
If anything makes the case for the complete abolition of the patent system, then the so called
FRAND patents are it. It's interesting to see how the notion is completely lost on some supporters
of the FRAND patent regime. Their argument is fundamentally the same as the people who reject
the notion of patents to begin with. It typically boils down to "Unfair!". Just much embellished
with useless appeals to emotion that differ not a whit from the arguments made against the patent
system in general. For example: "But how would my <pet company> be allowed to participate in the
market if someone OWNS this territory!?!one1eleven?". And: "This is not good for the consumer!".

Except of course when exactly the same argument is made against the patent system in general.
A lovely little retort to that has become a favorite refuge of the patent supporters:
"You just want to - " -- wait for it -- "STEAL!". Apparently, elementary logic is unavailable to
the so called inventors. Because, believe it or not, an argument has even been made that you're
not an inventor, unless you support the patent system. Even more, an argument has been made that
you're dirty thief... unless you support the patent system.

The patent system has outlived its usefulness. Nay, it hasn't been useful since day one. It arrived
stillborn, and its zombie has been haunting the inventors world over ever since it's been exhumed.

An impassioned appeal you say? A thousand times yes. The patent system is an unethical social
construct that has been perpetrated upon and abused... against countless honest, fair folks who
want nothing more than to practice the fruits of their labor. Many, many times their labor is
a function of an independent discovery. This is often challenged by patent supporters as impossible.
Their argument boils down to: "You can't invent FFT! Only the patent supporters can!"

Last of course, but far from least is the fundamental hypocrisy of this all: if you were to enumerate
everything the patent supporters use to practice their art, you will invariably find their contribution
insignificant, nay, not even visible when placed against the foundational background. They readily
accept locking out entire swaths of science and technology for themselves, without ever acknowledging
the monumental contribution of people... mathematicians, scientists... GIANTS!

Those giants, in their generosity and brilliance have made our world better. The patent system, I would
argue, has made our world worse.
"With Firefox OS, we can break open the world of native operating systems and closed platforms once again."

I'm not so sure they are solving the same problem they were solving before. "The web" doesn't have to be a browser anymore. It can be any app. For example, the Facebook app is a native app that makes a bunch of http api calls to provide the FB experience. Previously it was basically a web app with a native wrapper. In both cases you don't need Firefox to use Facebook.

I think native apps calling http services is a step fowrard in a lot of ways because if Firefox screws up or doesn't implement a feature the right way or whatever, your app isn't beholden to Firefox to fix their stuff in a future release.

Also, when there was basically just IE on Windows Firefox was definitely a reason for Firefox to exist. We have good browsers that seem to put a lot of effort into supporting mobile and HTML5. They're not perfect, but it's not even the same as IE6 back in the Win XP era.

Choice is good, but I don't think FirefoxOS is fixing anything.

Before you start with the growth hacking business, you may want to re-organize your site to provide clarity especially for first time visitors.
IMO, your CTA here is to have people browse through things..that whole sign up business on the left hand side is just a distraction.
I would present 2 columns with clear bold headings... "Things Offered" vs "Things requested" . I don't think there is any reason to have them as one continous stream.
Why do I have to give good things to great people around me?
Why can't I just give things to people for free? Whether they are great people or not is not my particular concern. Nor do I care if it is good stuff, as long as the person receiving it wants it..
Case in point, I want to get rid of an old TV..I'd give it away for free to just about anyone who wants it..my motive? To reduce cluster in my house.

You guys have a good thing going, but you may be overthinking it

You may not be familiar with the history of nationalization in Britain. (Apologies if you are.) We used to have many nationalized industries. They didn't work very well, but their prices were cheap. The Tory party and the New Labour party privatized these industries, and now they work even less well, and also charge very high prices and make massive profits for the prime minister's friends while still relying on massive taxpayer subsidies. So for us in Britain a return to nationalization would indeed be progressive.
Thanks!!! This is beyond awesome.
Hey all, I started the company formerly known as From Holden (we're renaming), and wrote all the copy for the Kickstarter campaign. I posted a reply on Dan's blog, would love to answer any other questions or hear any other thoughts there or here!

Oh, I know - I just did a double take, because for a minute I thought we actually had an internet minister. Government policy when it comes to all things digital is a total shambles, which is a real shame because on the one hand you have some parts of the civil service actively engaging with things like open data, open source, etc, and on the other you have the politicians being...well, politicians!
Oh no not at all, you're right. I'm not sure if this is the correct terminology but, googling it, I think it's called reserve requirement. "The reserve requirement sets the minimum reserves each bank must hold to demand deposits and banknotes." [1] An example they give is Hong Kong whose banks must hold 25% of their liabilities.

During the subprime mortgage, American banks (and some foreign banks but I can't recall them) were deregulated in a way that allowed them to have a higher ratio between their liabilities and what they actually held. This meant they could increase their financial investments without really having the money. I can't remember the exact ratio but it was something like 40-1.

Yes. You can tell by the about box - I lazily use the same style for every project!
My definition of reasonable is not about length, its about things like not asking for time off in the middle of an important deadline. Stuff like that.

Recent immigrants are a very small minority in the United States.

The articles I linked to discuss recent and not so recent immigrants, together with their children. The group being discussed is currently the largest minority group in the US.

The only reason they can affect the election is because approximately half of non-immigrants vote Democrat.

That is true because, as you note, immigration numbers are low. If immigration numbers do not stay low, that will change.

Hispanics whose family have lived in the United States longer than the United States has existed are far more American than European immigrants who came over last year.

Very true, though "americanness" is tangential to the point I'm making. Also, European immigration to the US is extremely small, and basically irrelevant to the numbers.
Simplest explanation:

Backbone is an object-oriented library that can increase maintainability for so-called single-page applications. E.g. it's often used in an architecture which pairs a dynamic web service with static HTML templates, CSS, and JS (no dynamic server-side HTML generation). In this way it is similar to ExtJS/YUI, but generalizes those widget-centric frameworks.

It's not for tightly-scoped JS enhancements.

In terms of patterns, it adheres mainly to the Model-View-Presenter pattern (embodied in the Model class, the HTML template, and the View class respectively). Switching between logical pages in the single-page app is supported by the Router class (which implement the front controller pattern). Data persistence/retrieval is oriented toward RESTful web services (this is customizable) and therefore pairs will with ActiveRecord-based server frameworks like Rails. The separation of concerns it encourages increases testability, and also allows it to pair well with asynchronous module loaders (e.g. RequireJS).
Im glad more people are pointing to this problem. Facebook is trying to silence the issue by implying it hasn't changed the reach of posts. In my case I saw a drop from 8.5 million people reached per week, to 2 million. Posting the same kind of content ive been posting for three years. Its a terrible thing to see that the people who have been creating content that has given facebook billions of ad pageviews, are now being squeezed in order to maintain the natural reach we once had.

Interesting. Alright, I'm going to look at the different sides and decide what I think.
Note that the source for that is_email test (I hadn't seen the library before) is here: https://github.com/dominicsayers/isemail

That library is very good for telling you exactly what's wrong with an email address, but looking through the logic, you can see that handling all the edge cases involves significant effort.

It seems to me that this monomaniacal focus on RFC 822 / RFC 5??? compliance is missing the point a bit. That stuff is important if you're writing a mail client or a server, not so much for a signup form or web site use.

I am going to stick my neck out and say that for the purposes of a signup form, emails should be server-side validated as: anyCharButNullOrAt@valid-looking-domain.com

1. You split the email address into a local part and a domain, at the @.

2. The local part is allowed to contain anything but null, or @. This will keep all the people who go john.doe+furrylist@gmail.com happy.

3. The domain section is validated against length and dns charset (letters, numbers, hyphens, dots) and then checked against e.g. the mozilla public suffix list for a valid TLD. This prevents admin@[10.0.0.2] from receiving signup emails.

4. After that you can punt to your mailer, as long as you do not give any feedback to the users (aside from reciept or non-receipt of email) on the success of delivery or verification (to prevent spam / bruting). Just say "an email has been sent", or somesuch.

Anyone with two @s in their email address ("foo@bar"@bar.com) or (foo\@bar@bar.com) is evil, and should not be encouraged. You have to draw the line somewhere, and that's where I draw it. One reason these people are not worth spending time on is because many common clients such as gmail won't let you send to such addresses in any case. Try it...

Let's thank our stars we don't have to handle Unicode addresses yet...
@work we have done a lot of this kind of validations using a custom Tcl script, and luckily we have avoided to be blacklisted till now. Maybe it's due to the fact that validation requests come from an IP address marked as MX for the domain of the sender email address.

Anyway not all SMTP servers are RFC compliant, they respond with a 2XX code to a "RCPT TO" even if user/mailbox doesn't exists. The same thing applies also if the SMTP server is acting as a relay and has no immediate access to the delivering system.
Let me preface by saying that I'm by no means a Kickstarter expert.

I think Kickstarter is fully focused on creative projects that do actually create things. Each project has to have a clear end point and well-defined creation. It definitely isn't made to clear out old inventory -- so in that sense, it isn't a store, but for those of us that need resources and scale to manufacture a product, it is hugely important, and a lot of their focus.

I do think there are a lot of ideas like categorization and tiering that could help people better understand Kickstarter, and I think they'll continue to refine the concept, of course.
There are at least 40 million people who either have green cards or have become citizens, who were not born in the USA.

Plus all the illegals who are not supposed to vote (but it is reasonable to assume that some small percentage of them do).
We're still talking well under 1% annually.

I.e., 10% over 10 years. Or 20% over 10 years if we double our immigration rate.

Note that I'm generally in favor of increased immigration, I just don't think we should ignore the possible negative consequences.
