We already have automatic ground turrets that use heat signatures and computer vision

But at the end of the day, everything loses against a single nuclear bomb.

Curious to hear whether these weird Linux-asymmetries apply to Blu-Ray or online digital media (e.g. Hulu/Netflix) too.

I would be willing to accept the fact that DVDs were invented so long ago that some of their restrictions are a little archaic.

Yeah, heh.

I totally Amazon Subscribe-and-Save all my toilet paper now (but I don't always like to admit it)

I'd be curious to hear who you think the target audience/demographic is for your landing page.

In particular, I find that the page is succinct at describing "what" AppScale is but not "why" I should click either Join or Download within the first 45 seconds

What's crazy is that Facebook has only been a public open-signup website for ~6 years, and it's so tempting to assume it will be around and popular forever -- I mean, why wouldn't it?

But at the end of the day we really have no idea what the world will be like in 15 years.

It only took MySpace 3 years to fall out of favor.

Interesting presentation, but it can't be the whole story. Even projects like SciPy which use the most rudimentary data structures (basically just a large array of floats) and algorithms (sometimes just looping through the elements in order a few times) see a considerable advantage when rewritten in C.

Heh. Not the first time it's happened :P

It's actually based on the ambient Wi-Fi signature of the airwaves around you. There is no image recognition involved!

In our experience, we've found that most access points do in fact have a fixed power. Either way, the system can accomodate some amount of dynamic changes.

Fair enough. We have a 90 second video on YouTube that should give you a sense of what you'll get: www.youtube.com/watch?v=B_GdXp_Swjs

But basically, yes. It lets you build indoor positioning by walking around my room.

I thought this was super-clever when I first came across DiffBot last year. Can't wait to see what they come out with next.

Keep it up!

@untog: It's actually a sensor fusion approach that combines both accelerometers and Wi-Fi signals.

Oh also, if you're up for learning more about the technology/platform in general, take a look at blog.wifislam.com

If you don’t have time to try the app, watch this video instead. It’s 90 seconds. www.youtube.com/watch?v=B_GdXp_Swjs
