Location Web

Location = context

Context -> higher relevancy -> user experience

Location is a killer mobile app enabler

Fire Eagle – location broker (get all inputs, have app (publisher) registered). Dopler as publisher. Fireball get access for the info

DO use FireEagle PHP library! (Update, query, integrate)

Geolocation methods:

Triangulation (WiFi 20[m], GPS 1[m], Cell Tower 2000[m]) {Loki JavaScript API} Garmin device plug-in, get path data GPX

Association (IP Geolocation) {quova, ip2location}

Geo Term Extraction {MetaCarta Query Parser API, Urban Mapping GeoMods}

Posting to FaceBook feed using Graph API

Graph API was announced at F8 with a promise to dramatically simplify the FB API. I checked the read access over the new interface during the presentations and to my big surprise it worked flawlessly and from the first time. When I tried, JSON-formatted info about the FaceBook page was returned (as expected).
Then I tried OAuth 2.0 way of accessing the API to post a message to the feed. And to my even bigger surprise it worked too!
Here is what you need to do to access Graph API over OAuth: 1. Create a FB app, store app properties to a file:
$appkey='7925873fbfb5347e571744515a9d2804'; $appsecret='THE SECRET'; $canvas=''; 2. Create a page that will prompt user the access permission (I am prompting for the publish_stream and offline_access permissions at the same time)
// require'settings.php';
$url=""; $url.=…

Developing Google Glass application showing the Heart Beat Rate

Wearable Sensors + Google GlassWearable sensors  are a lot of fun! I played with them for some time by now, both professionally (at work), and for the coding pleasure. This post is about my latest weekend project - native google glasses app showing heart rate. The idea is to continuously measure hear rate using the sensor and to show pulse rate in real time, for example, while running or exercising. Honestly, I did not find running with Google Glasses to be much fun (as they tend to fell off when I am running), but to see what makes my heart beat faster is an interesting and educational experience.

Google Glass (GG) Turns out to be a nice piece of hardware that is a fun to work with: reasonably fast processor, Android 4.0.1, wide range of sensors, WiFi, and Bluetooth interface!

Respect Coin

Respect I think it's time to talk about currency. Let's create a Respect Coin.
Step 1. Install OpenZeppelin library npm install zeppelin-solidity
When it comes to coins, I like to use some functions that smart people already implemented and other smart people verified. I think that Zeppelin is a nice collection of Solidity contracts that can be trusted. Let's use the StandardToken contract and use it as a parent class for our own RespectCoin contract.
Step 2. Create RespectCoin contract and store it in "contracts/RespectCoin.sol" file pragma solidity ^0.4.4; import "../node_modules/zeppelin-solidity/contracts/token/StandardToken.sol"; /** * @title RespectCoin * @dev ERC20 Token example, where all tokens are pre-assigned to th e creator. * Note they can later distribute these tokens as they wish using `transfer` and other * `StandardToken` functions. */ contract RespectCoin is StandardToken { string public constant name = "RespectCoin&quo…
