barecode reader;What does a barcode contain? Is a barcode readable? Test and control barcodes!

barcode reader: read barcode from image 

an image (via a webcam for example)-->EAN code ( a number)

http://bytescout.com/?q=/products/developer/barcodereadersdk/bytescoutbarcodereadersdk.html
Reads barcodes from images. Supported symbologies: Code 128, Code 39, EAN-8, EAN-13, UPC-A, UPC-E, Interleaved 2 of 5, Codabar, EAN-2 and EAN-5, DataMatrix and PDF 417.

bcTester reads barcodes from images or PDF files. Linear barcodes can be recognized as well as modern 2D-(two dimensional) barcodes
Find out what is encoded in the barcodes you see!
Just create an image file by scanning or taking a picture of the barcode, and bcTester reads it from the file.

Rem:
A barcode is an optical machine-readable representation of data relating to the object to which it is attached.http://en.wikipedia.org/wiki/Barcode
The mapping between messages and barcodes is called a symbology. The specification of a symbology includes the encoding of the single digits/characters of the message as well as the start and stop markers into bars and space, the size of the quiet zone required to be before and after the barcode as well as the computation of a checksum.
A barcode reader or barcode scanner is an electronic device for reading printed barcodes. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Additionally, nearly all barcode readers contain decoder circuitry analyzing the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port.
The Symbology Decoding Algorithm for barcode scanners is the first symbology-based algorithm for decoding. The new technique utilizes information from the entire image to detect transitions in the signal, whereas the traditional algorithm relies on the maxima and minima. Traditional methods are prone to errors because the method relies on a derivative; they are also sensitive to noise and blurring. The Symbology Decoding Algorithm for Bar Code Scanners exhibited high resilience to blur and noise when tested on 1D Universal Product Codes. The algorithm can also be extended for use on 2D Universal Product Codes

 Scan barcodes on products then look up prices and reviews. You can also scan Data Matrix and QR Codes containing URLs, contact info, etc.
Also share your contacts, apps, and bookmarks via QR Code. This is why contacts permissions are needed.

The top 10 ways to embed Google Earth content (trails, footpaths, interactive guide to fishing, walking, biking) on your site blog (special mention to blogger) with or without earth plugin and with/without earth API

A) without coding (no javascript)
3 categories of methods: without the need of plugin install (Google Earth plugin, for browsers) and without the google earth API or with this API (in this case, the client must install the  Google Earth plugin)

A-a) without the need of Google Earth plugin
A-b) without the google earth API 
A-c) with the google earth API 

B) with coding (javascript)

-----------------------------------------------
-----intro (not necessary if you just want a one-click service to directly embed in your site)

The Google Earth plug-in allows you to navigate and explore geographic data on a 3D globe using a web browser: http://www.google.com/earth/explore/products/plugin.html
If you want to embed the Google Earth plug-in on your website, visit the Google Earth API site to learn more: http://code.google.com/apis/earth/
Check out the recently revamped (2011) Earth API Developer's Guidehttp://code.google.com/apis/earth/documentation/

This plugin and this API may work correctly on all browsers (Internet Explorer 7.0+, mac and PC: Firefox 3.0+; Google Chrome 5.0+; Safari 3.1+, etc...) that support NPAPI with npruntime extensions (https://developer.mozilla.org/En/Gecko_Plugin_API_Reference:Scripting_plugins).
Plugins (or plug-ins) are shared libraries that users can install to display content that the application itself can't display natively. For example, Adobe Reader plugin (or Google earth plugin) lets the user open PDF files directly inside the browser. Plugins are written using NPAPI, the cross-browser API for plugins: https://developer.mozilla.org/en/Plugins

To install the Google Earth Plugin, browse to any page in which the plugin is included or at http://www.google.com/earth/explore/products/plugin.html (at this URL, you can see the version of your plugin).

This plugin and this API offer many services, see these 2 "ex-amples" (trail):
(google maps and google earth and a path from one start address and one end address)
http://www.themountainpulse.com/trail-maps-plus/grand-teton-national-park/ (The Mountain Pulse is an online resource for Jackson Hole’s outdoor community: mountain biking, hiking, pathways cycling, fishing, kayaking, lodging and more)

---after this intro, let's start!
from http://code.google.com/apis/earth/documentation/

To load the Google Earth Plugin in your web page, you need to:
  1. Load the Google Earth API.
  2. Create a DIV element to hold the plugin.
  3. Create functions to initialize the plugin.
  4. Call the initialization functions once the page has loaded.
