The study of game theory and incentives has become a big area of study in marketing. I worked in an experimental economics lab for a few years and a lot of the software we wrote and experiments we ran focused on little incentives like this

Good way to describe those 1-off/advanced initiatives. It really does seem like a hedged bet in some cases and a great way to keep people inside the company engaged/curious/thinking outside the box. I thought Google was also doing significa

Another tip for the manual-scanners out there to make that for-loop a little bit faster: for(int i = 0, len = text.length(); i < len; i++) { // do something } avoids the method call to length() in the comparison expression

Joe, if you look at the Howto it shows when you setup the balancer you assign it to a data center (like NJ) and I assume it balances nodes only in that data center otherwise what would be the point of assigning the BalancerNode itself to a

Did anyone else read a lot of anger/frustation in this piece? From Matt's quote, I just got the impression that sub-domains are an option and that GBot treats them as logically cohesive groupings of information, I didn't see anywhere that h

Same here. bulldozer got pushed out again, some folks are saying the silicon was underperforming by more than anticipated so they have to keep it I the lab and rev stuff NOW that they had planned for the refresh in 2012. Then we have ivybri

Did not know this, love it and am also amazed that all of us are alive right now in an era where humans are dabbling with technology that is starting to ram right up against (perceived?) physical limitations.

farico, you are exactly right, and that is the point. You just add mirrors to make the distance needed shorter and shorter. I was just taking the example to a logical absurdity to reason that we could potentially make a small array of milli

rmc, good point about the specifics of Mars. The range I found is 100-400 km. I think the (useless?) point I was making still more or less holds, but my calculations need asterisks next to them with a clarification at the bottom: "Would req

hugh3, you are exactly right. I updated the original post as I was thinking through how this amazing physics experiment could be helpful, and it dawned on me, it wasn't. I could just use my Canon to accomplish the same thing. I think my bra

Certainly a good suggestion, but I just laughed at the potential future-irony of him building it, and then suddenly being up to his neck in code, and being back here on HN posting stories about how to scale your startup on EC2 :)

Fascinating question and fantastic answer. That being said, as Edgar added to Vintage's answer, if you put a mirror 13.5 light years away, and watched your reflection from earth, that would be the same as being 27 light years away. So if I

I didn't know what Project Harmony even was and that article doesn't clear it up in the first few paragraphs. For anyone else fuzzy as well, it looks to be "a standardized set of contributor agreements (to the linux kernel)"[1] [1] http://

Other excellent points; I hadn't even considered the deployment/update scenario and how many different ways that problem has been solved and re-solved in different languages to just try and make it easier (Installshield, OSGI/Eclipse Update

Chris, love that you are keeping up with sharing these numbers with us even as things grow and get more "serious". Glad to see you have an eBook out and that income, month over month, is up. Best of luck!

Glad to hear this, for some rough math the 20,000 liters of vegetable oil (unprocessed) is roughly 5,200 gallons[1]. Let's assume we lose no volume during the processing to biodiesel, the average semi carries about 200 gallons of fuel[2] --

Colin, just grabbed it from Amazon. This is exactly the type of resource I wanted to go through before going live with the API. Thanks!

Vitaly, So something like: GET /image.json/pig.png?size=150x100 as opposed to GET /image.json?id=pig.png&size=150x100 where the arguments specific to the noun (or object/entity or image resource in this specific case) go i

I thought I finally had REST figured out until I read this. Does anyone else see a diminishing return on pedantically following the REST-prescribed design and actually creating an API that people are familiar with out of the gate? I feel

I like this idea, my gut tells me there is something in that arena to be solved with some simple like this (maybe even a universal JSONP callback method definition for an endpoint or something for services that you can call out to for thing

Adding to the thread, anyone that needs to deal with Windows XP or Windows Vista installs, nLite[1] and vLite[2] are in this same vein, but help you build custom installs. (Also forgotten this one about once a year). [1] http://www.nliteos

Gotcha, thanks for clarifying. I agree the demand has to come from the consumer end first no matter how hard devs push out.

It's hard to tell how it performs in real life (not a launch video) but that being said the demos of it in action were impressive. I wonder if this is the form the Holodeck/3D technology we've all been waiting for since the 70s will be in.

Very impressive Derek -- how easy was it to work with the Kinect data via the API? Is the information coming out of the sensors pretty straight forward or does it just come in as a video feed with additional metadata (positional?)
