A Clear Explanation of Tracking Cookies (All Things Digital)

Just ready a story relating to Yahoo on All Things Digital today and noticed they do a really nice job of explaining their use of tracking cookies:

Some of the advertisers and Web analytics firms used on this site may place “tracking cookies” on your computer. We are telling you about them right upfront, and we want you to know how to get rid of these tracking cookies if you like.

I’m impressed with the visual treatment and the fact that they’re very upfront with this information. Of course you’ll only see this message once (or whenever you clear all your browser cookies), but it’s a big improvement over most sites.

For more details on tracking cookies, see the EFF’s coverage of online behavioral tracking.

Fiddler Web Debugging Proxy With Any Browser

Fiddler is an extremely useful tool for debugging any web traffic on Windows environments. From their website:

Fiddler is a Web Debugging Proxy which logs all HTTP(S) traffic between your computer and the Internet. Fiddler allows you to inspect all HTTP(S) traffic, set breakpoints, and “fiddle” with incoming or outgoing data. Fiddler includes a powerful event-based scripting subsystem, and can be extended using any .NET language.

I originally used Fiddler back the early days with Internet Explorer, but have recently picked it up again for use with several different browsers. Although some browsers have more native capabilities now (like Firefox with FireBug), using Fiddler consistently makes it a bit easier to concentrate on the problem at hand rather than the tool itself. Fiddler can also handle and decode HTTPS traffic now.

Setting up Fiddler with different browsers is pretty straightforward:

  • Internet Explorer: No changes needed; when Fiddler is running it will automatically pick up all IE traffic
  • Google Chrome: Same as IE (automatic)
  • Apple Safari: Same as IE (automatic)
  • Opera: Same as IE (automatic), but may need to start Fiddler before Opera
  • Firefox: Change network options to use the HTTP proxy at address, port 8888; also see the Fiddler Firefox addon
  • Curl: Curl from the command line is very useful when testing webservices; to route through Fiddler, just include the proxy option like --proxy
  • Other Apps: See the Configuring Clients help page for any other application which lets you configure a proxy
  • Mac/Linux: For cases where you need to debug on a different platform, you can still route traffic through Fiddler on a Windows system; after starting Fiddler, set up the application on Mac/Linux to use the proxy at windowshost:8888

For more background and “how-to” guides to get started with Fiddler, check out the Fiddler help page.

Mobile Browser Share on

The changing landscape in mobile device and browser market share has been a hot topic in the news lately. Last night I took a look at the numbers for, my directory of mobile website links. I used the Google Analytics data and in particular the mobile device detection capabilities. This accounts for about half of the traffic, with the other half being desktop browsers or “unknown”.

The following chart shows the percentage of the top 8 platforms visiting over the last nine months:

Chart: visitor platform breakdown


  • Android is the big gainer, growing from 4% to 21% of traffic
  • Blackberry gained from 16% to 24%
  • The above gains seem to be at the expense of Windows devices which dropped from 31% to 15%
  • iPhone + iPod share remained about the same
  • Symbian, Samsung and Palm all dropped slightly

How to Remove Yourself from

Update 2012-02-23: See a newer version of this article: How to Remove Yourself from and

Having a result on Spoke when searching for your name is a drag. In addition to their reputation for being spammy and intrusive, the data listed is often inaccurate or out of date. To remove your profile from such public searches, their FAQ provides the clue in the answer for My information in Spoke is wrong. How do I update it?:

… Go to, search for your name, click your name to access your profile, then click the “This is me” button to update your profile and set privacy preferences. … If you would prefer to permanently suppress your information from Spoke’s directory, access your profile as described above, click the “This is me” button, select the “Learn more” link, then see instructions in the “How do I claim and update my Spoke Profile?” section.

After following these steps, my page still shows up in search results, but presumably that will stop at some point. In any case, anyone clicking on my profile will just see the message “This profile is no longer available”.

I recommend not installing their toolbar or providing any further information on the site. You should be able to give just enough to “claim” your profile, then disable the public view of it.
