Panopticlick – How unique – and Trackable – is your browser?

Monday, June 27th, 2011

Is your browser configuration rare or unique? If so, web sites may be able to track you, even if you limit or disable cookies. Panopticlick tests your browser to see how unique it is based on the information it will share with sites it visits.

So I ran the test on the following browsers…

	Works	Identifying number of bits
Internet Explorer 9.0	Fails	—
Safari (Mac)	Yes	20.65
Firefox 5.0 (Mac)	Yes	20.65
Android Native Browser	Yes	20.65
5o9 Browser2	Yes	20.65

Interesting item… Androids NATIVE Mobile Browser does NOT support the following:

DOM localStorage: NO, DOM sessionStorage: NO, IE userData: No

However if you run the same test in KeyNote’s MITE (Mobile Internet Testing Environment) it will indicate that it does support it.

Real time Automated Mobile Web Performance Testing

Friday, June 10th, 2011

Where? LAX along the taxiway to the terminal.

How? 9 lines of code!

Knowing that your page loaded quickly — “Priceless”

Here’s the 9 lines…

<script>
function do_google_loop_test()
{
var urls = “”; // The list of URLS to AUTOTEST

urls += “http://www.google.comn”;
urls += “loop delay 30n”;

js5o9.autotest( urls );
}
</script>

The Unpredictability of Mobile Web Performance

Friday, June 10th, 2011

I’ve been running some Mobile performance tests from different locations and was surprised by how much they differ.

Now obviously the tests below are not “exhaustive”, but it does illustrate how different locations affect Mobile Performance. 4 tests were done on the East coast, the remainder in Denver, CO. What’s amazing is the byte count of the Google home page. It’s almost double at the major airports. (The yellow triangle indicates that the page has JavaScript errors). Why should that be the case. What is different on their Web page served to the airport that is different everywhere else?

As we move to a Mobile Web it’s important to consider the location of the device as well as the size of the content you’re delivering. More and more web pages will query the location API found on these mobile devices. Combining that with page size control will be critical to ensure the optimal experience.
