TechCrunch attributed Groupon's early success to their clever social engineering. This NYT Writer focuses on the clever copy, but I tend to agree with Sarah Tavel who says its all about the savings: http://www.adventurista.com/2011/04/stop-calling-groupon-soc...

It would be interesting to test. Write some dry copy, make the "tipping point" 1 coupon and see if it sells less than the funny/social counterpart.

You really don't need to go that far. Living Social is rapidly catching up to Groupon with fairly bland copy.

Can an artist make great art without knowing to use oil paint on canvas, instead of watercolor (or whatever - I'm not an artist)?

How about knowing the difference between types of brushes and what effect they have on the canvas? Is it 'great art' if it's accidental?

Facebook is slow, I know. I have introduced it just now and will work on the speed and bring it up to speed with the Twitter version.

Will work on the styling as well and ability to like, comment and yes more options of the kind of people displayed based on post frequency is a very good idea. Thank you.
What a complete nonsense. The industry moves in certain directions, and everyone is inspired by everyone else. Because there is a thriving legal industry, they call iit "stealing ideas" and "copying". There is no such thing as original design, every design is based on previous designs and adds small new things.

The only group really benefitting are the lawyers and their surrounding workers. Not our innovating tech industry.
It's sad that "Toy Story 2" didn't make the cut. I think it's a stronger movie than the original with a better villain, a bit of Shakespearean mistaken identity, new characters that you care about, and foreshadowing for the final movie (Stinky Pete asks "Is Andy going to take you to college?" and claims they'll all end up in a landfill.) The climatic scene at the Airport is almost as good as the "Bird Rescue" scene in "A Bug's Life" (which I contend is one of the best action scenes in any animated movie).

In fact, the only thing I don't like about it is how easy Woody gives up on Andy. Woody is, in my opinion, Andy's surrogate father and probably should have come up with "Come with me to Andy's House" much sooner.

Their method captures a light field instantaneously at
the expense of spatial resolution. They place a microlens array where the film would be, followed by a sensor. Each microlens forms an disk on the sensor with angular light distribution. Developed in Mark Levoy's group http://graphics.stanford.edu/papers/lfcamera/

I guess Ren Ng is behind the company as he was first author:
http://graphics.stanford.edu/~renng/

This method works nice for photography where all the dimensions involved are much bigger than wavelength.

The URI fragment makes single-page web apps possible. It removes the waste of having the browser re-parse DOM and re-interpret Javascript each time the user switches interfaces.

One disadvantage is that the Referrer header does not include the fragment identifier. But that's a problem with the Referrer header and not necessarily the fragment identifier.

The fragment identifier has been a part of the web for years, for the purpose of describing the user's state on the client. It's just that we interpreted this as just meaning "bookmarks" and didn't use it for anything more than that. We've only recently started to understand the fragment identifier and use it more fully.

Stallman lays out the choice he had to make clearly, and he made a valid choice. That choice does not constitute /his/ boycotting Israeli Universities at all, only declining to cause distress or offence to the people who are paying for his trip. Based on his own account, he would be happy to speak at Israeli Universities, so the title of this post is wilfully misleading.
Kind of interesting. Somebody has to do it I guess. But its not as flashy as they think - refocus the picture? Or focus right the 1st time I guess. Zoom? Enough megapixels and what else? Nothing I suppose.

I'm a bike commuter as well and I love it. Been doing it for about 9 years now. The first 2 years it was a 40 minute bike ride each way. After that I got another job and moved which resulted in a 15 minute ride each way.

Funny thing is I kind of miss the longer commute. Sometimes after work I will take an extra 30 minutes on my bike by taking the long way home. How many times do you hear a car commuter say that?
All engines do save queries. I don't believe there's much hope of seeing any engine renounce to this data opportunity.

Users though, could keep better track of their queries and selected results. Saving this data locally on their machine is an option. This is useful for recall, but also allows to share queries and results with others. The latter allows to build various result and query recommenders.

For instance, http://www.seeks-project.info/ lets you share your queries with others so you can benefit from their work on the results. You can play with it by using the demo server http://www.seeks.fr/

I suppose using this for tagging stuff has two positive side effects:

1) You can now use longer tags, with whitespace, capitalization, etc.

2) Duplication of tags is much smaller.

Kudos to the author.
It's extremely interesting, for two groups of reasons: (1) creative possibilities (playing with depth of field is my favorite part of photography); (2) market applications.

Regarding (2), if I understand the paper properly, this should allow for a massive increase in lens quality while also allowing for lenses to be much smaller. Both are worth tons of money... together, it's massive. As a guy who carries around a $1900 lens that weighs 2.5 lbs, because of the creative options it gives me that no other lens can, this appeals to me greatly!
It's likely the age. At 26, friends start drifting away and it's hard to make new ones. People have less time and inclination to spend hours on the phone at this age.
1 is cool. I worked at a company where we discussed doing this with carriers for their corporate customers, where obviously you have all the historical data and tariffs. On the technical side every bit of activity was an event, so we could easily replay it through a theoretical tariff, and we wanted to use genetic algorithms to come up with new, better tariffs (which were pretty complicated as they involved various different international voice and data rates). You might think it was in carriers' interests not to do this as they make tons of profit on their customers overspending, but apparently not.

We never ended up doing this, however, and most of their tariff discussions continued being back-of-cigarette-packet calculations.

The idea and technology would actually be applicable to all sorts of domains - utility bills, for example.

You could use something like grinder (http://grinder.sourceforge.net/) to create a loadtest scenario which you can use to establish a baseline before a change and run after a change to assess impact.

True loadtesting requires quite a bit of thought to go into your test-setup, but for those kind of differential tests it is usually enough to make sure that your test-client and network connectivity to the application are constant factors and good enough to generate a decent load.

You won't catch the subtleties with those tests, but you will normally catch the 'oops, my perfomance dropped by 50%' type of errors. The subtleties you can then work out during normal operations.
Mark Levoy (and his group) do all these things.
However, if one wants to track through crowds one needs a much bigger aperture. So one would combine many small cameras into an array as opposed to a microlens array infront of the sensor.

Presumably if we could extend life, we could also extend the period of life in which you can produce and create useful things. There would be little point extending lives if it meant you spent an extra 30 years confined to a bed with no memory of your identity.
Big lenses are always better as they collect more light.
If one uses a 10M pixel sensor in a light field camera, one will have to reduce the resolution of the output image by a factor of 10 in both directions (depending on what microlenses one chooses).

A Print Reader Is Worth 228-Times As Much As An Online Reader
Before I read the paper, I was adamant about "more light is better." But read the paper:

"We show that a linear increase in the resolution of images under each microlens results in a linear increase in the sharpness of the refocused photographs. This property allows us to extend the depth of field of the camera without reducing the aperture, enabling shorter exposures and lower image noise."

You're right that you still need good, small sensors to enable good, small lenses, but my ultimate point is that digital camera sensors scale with advances in silicon. Lens technology is much, much slower to advance. The more of this we can do in software (and thus, silicon) the better.
Sounds like you guys should be writing the marketing prose for those guys.

If your interested in this and you have an Iphone you could try this app: http://sites.google.com/site/marclevoy/

It captures a video wihle you move the Iphone camera and combines it into an image that looks like it was captured with a big aperture.

I don't have an Iphone and have never seen this app in real live, though.

Comments are data points and there's no reason to hide them.
It does work in FF4, but it's not widely supported enough to rely on just yet, you're right.

I also find the best thing to do is use a hybrid approach (pushState where available, hashbang as a fallback.) If anyone else is interested in implementing this, there are some good frameworks[1][2] to give functionality similar to pushState via the fragment identifier.

Note that these constantly poll the hash in browsers that don't support the onhashchange event. It's a good idea to turn down the polling frequency to half a second or so, because I've found it can cause performance problems in IE.

...but Amazon certainly paid the royalty. So it did cost them the stated amount of money.
Micropayments need to be treated like pre-paid activities like consuming gas when you drive from one location to another. i.e. the decision to spend money must be automatic based on your behavior. For example, when I drive to the store, I do so without ever thinking "it's going to cost me 14 cents in gas to go there and back. Am I sure I want to go?"

For micropayments to work, consumptive behavior needs to be used as a proxy for a decision to purchase.

One guy doesn't screw up a whole project. Estimates should be reviewed, progress tracked, requirements managed and scheduled. Who should do that? In part, your boss.

If your boss is upset, it because they failed to keep on top of this. If you're fired, its because they need a scapegoat.
Could this be used for completely automated exemption of objects based on the focus range? I think, with a clever algorithm which analyzes the sharpness of all these layers it migght be possible.
I don't know if this technique also expands to moving images, but if so, maybe it could also be used to automatically composite those. Without the need of a green-screen whatsoever. Basically, you would be separating the image layers based on distance instead of chroma.
Interesting. RMS is aggressively against software coercion but ambivalent to political coercion.
Related to this and presumably not common knowledge is that there was recently a breakthrough in camera CMOS sensor technology.
A few companies now offer scientific cameras (price tag 10000 USD, for example
http://www.andor.com/neo_scmos) that allow read out at 560MHz and 1 electron per pixel readout noise as opposed to 6 electrons per pixel in the best CCD chips at 10MHz.

This means one can use the CMOS at low light conditions and at an extremely fast frame rate (the above camera delivers 2560 x 2160 at 100fps). You will actually see the poisson noise of the photons.

Unfortunately representatives (the few I spoke with) of those companies don't seem too eager to bring these sensors to mobile phones.
I feel as if I have tried near every to-do, GTD, or similar type app on the desktop and web and there is one feature that is always, without fail, missing and one that usually is.

The first is the ability to allot to a task how long it should take (E.g. Buy milk - 15m, Create wireframe for client x - 30m). The only place I have ever seen it, as far as I can recall, is Action Method.

The second is the one you mentioned.

Admittedly they are both quite similar though there is a distinct difference in usage.

> A polarizing and emotional rant with a five-star/bright-green/100%-bar rating is barely less susceptible to mob voting than a polarizing and emotional rant with 55 points.

IIRC, the comments I made that got the highest scores were accidental emotional rants that, more than embody some clever original insight, were in agreement with a large number of people. Usually the well reasoned ones get around 5. To get above that, I'd really have to play for the crowd, something I am not inclined to do. I value this place.

Replacing the green screen doesn't seem to make sense.

For macroscopic objects depth reconstruction with two cameras like in the Kinect seems the better alternative.

Object excemption seems to be a nice idea. I can't remember having read anything about this. In principle it should be possible to recover an unsectioned stack of images.

One can then use an iterative algorithm to subtract in-focus information from on slice of the stack from each of the other slices and end up with a deconvolved image of sectioned images.

Then one could delete one object in the stack and recalculate a superposition of blurred sectioned images to recover a reconstruction representing the object without the image.

This is quite complicated. Just imagine to remove a wine glass from a scene. One needs to delete all the rays that went through the wine glass and bend them such as though the wine glass wasn't there.

One can argue that polarization and absorbtion effects will be very hard or even impossible to handle correctly.

Certainly light fields contain A LOT of potential.
You have to remember that facebook is a compiled binary (hiphop). They entered the release cycle they did vs true Continuous Integration because original compilation times for this binary were extreme. Pretty sure Chuck mentioned something in the range of 1gb binary. They've corrected the amount of time it takes to compile and can push within 15 minutes of a trunk merge, but it's stil not on the scale of a few lines here, a few lines there.
If they are actually working on the iPad 3 or iPhone 5, it would not be wise to ignore a court order and ship something else.

HackerNews London Meetup: One Year On
I do. I follow HN using a RSS feed ( http://feeds.feedburner.com/newsyc100 , from http://talkfast.org/2010/07/23/a-cure-for-hacker-news-overlo... ), and I often read a submission and its comments a few days after the discussion has died down* .

Seeing comment scores is useful, because it lets me easily see the "best" comments. I don't see the problem with showing comment scores once the discussion has died down.

It's also useful to be able to see comment scores when browsing old threads, looking for specific information (using searchyc, bookmarked threads...).

*: of course, this approach is good for simple HN "consumption", but participating is harder, since few people reads the comment I make on week-old threads...
If anybody has any feedback or suggestions on the format of the meetup we're all ears!

Also get in touch if you'd like to speak at one of the future events.
