This gigaom post has more details on iBeacon: http://gigaom.com/2013/09/10/with-ibeacon-apple-is-going-to-...


iBeacon’s range is 50 meters (typical Bluetooth range), or 2,500 square meters.

That's some weird antenna right there. Assuming it's omnidirectional with a 50m range (radius) then it would cover more like 7,800 square meters.

The range of Estimote’s beacons is 50 meters, but the recommended range is 10 meters. If you go with the recommendation, you need 1 Estimote beacon for every 100 square meters.

More like 314 square meters.


> 2,500 square meters

I'm not sure it's a weird antenna. Looks like the author took 50^2 (square with edge length 50 m) instead of \pi 50^2 (the traditional interpretation of 50 m range).

But you can't pack circles tightly -- you have to use hexagonal cells.


Hmm, reading that after the estimote pages makes it seem that the gigaom post is just guerrilla marketing for estimote, that's trying to hijack the Apple publicity.

Have Apple actually stated anything public other than the word "iBeacon"?

Googling around I just find the same rewritten PR material all about estimote, not iBeacon specifically.


Hey, this is Jakub from Estimote.

We have been working on wireless Bluetooth Smart beacons long before Apple made it part of their Core Location API and called iBeacon.

If you would like to learn more about Apple iBeacon you could check it here: https://developer.apple.com/library/ios/documentation/CoreLo...

Our API and BLE beacons in general are explained here: http://www.estimote.com/api


This is a fantastic collection. Thanks for sharing this!

I imported mine to Evernote a while back. They have an import from delicious tool.


Just went looking for this and couldn't find anything. Pointers?

Note: imports all to one note so not the ideal.


They discontinued the delicious import tool for some reason -- some technical reason from what I understand.

However, if you apply for an API key, there are scripts out there that can parse the delicious export and import into Evernote, including tags. Google for 'delicious export evernote script'.


Or a few mint leaves for a soothing flavor...


There are a few sites that already do that, but I've personally never used them.

There's a wiki that has solutions to the exercises at the end of all chapters. http://www2.algorithm.cs.sunysb.edu/mediawiki/index.php/The_...


Is this the beginning of integrating all personal info stored in various Google products under one search box?


Not sure if it was meant to be this way.. but the design looks eerily similar to facebook's.


purely coincidental


Are you sure? It seems to be as if you just took their source code - you even have their logo in the top right corner.


I love 1984. I wouldn't say it was inspiring (its dystopian) but rather an eye-opening experience. It made me change the way I look at security and privacy.


If you liked 1984, then you might also like "We" by Yevgeny Zamyatin: http://en.wikipedia.org/wiki/We_(novel) (don't follow the link. copy-paste it with the (novel) part.)

I've never read 1984 (I hope to when I make time), but I understand that they are similar. In fact, I heard that "We" was the inspiration for 1984.


Read the whole set:

We

1984

Anthem

Brave New World

I love dystopias, and these four have always seemed to work together, to me.
