  • IE 8 - IP Address Mapping Accelerator

    On the ASP.NET forums where I moderate, the poster's IP address is displayed at the bottom of the post. Often I am curious and paste the poster's IP address into an IP locator web page to find out where they are posting from. This was tedious.

    Once I installed Internet Explorer 8 and saw what accelerators could do, I decided to write one to do the work for me. It wasn't too hard.

    Here is what the accelerator text looks like (it's just an XML file):

    <?xml version="1.0" encoding="utf-8"?>
    <os:openServiceDescription xmlns:os="">
        <os:name>Map IP Address with Info Sniper</os:name>
      <os:activity category="Map">
        <os:activityAction context="selection">
          <os:execute method="get" action="{selection}" />

    To install an accelerator, you have to launch it from a web page. This is annoying. I tried to make the URL a local file but that did not work. I ended up with this:

    <button id="myButton" 
      Add Info Sniper Accelerator

    The button rendered:  


    Here is what it looks like in action. Highlight the IP address, right click and…

    Here is part of the resulting InfoSniper web page:


    If you want to install this accelerator click this button: 

    Here are some Microsoft's accelerators:

    Here is the Developer's Guide:

    I hope someone finds this useful.

  • IE 8 Can Profile JavaScript

    Being on the software "bleeding edge" is similar to being the "point man" in combat. I generally avoid being the first to adopt new technology until some other poor bastard has led the way…and occasionally paid a price: The price being missed deadlines, ulcers and ruined reputations. No thanks.

    However, with Internet Explorer 8, for some inexplicable reason, I jumped right in. And I was pleasantly surprised. One of the nicest features is the new Developer Tools toolbar that comes with IE 8. Previously the Developer Toolbar was an add-on.

    On the Developer Tools window there is a new Profiler tab. Since there have been recent performance issues on the Asp.Net forums where I'm a moderator, I thought I'd give it a spin.

    • I clicked Start Profiling.
    • I navigated to the Asp.Net forums website.
    • I waited for the page to finish loading. Having the Profiler running slows things down quite a bit…which is understandable.
    • After the page had finished loading, I clicked Stop Profiling.

    It was that easy. The results are below. It appears the getAvatar function is taking a lot of time. If each call to getAvatar results in a database call, and each call results in an image being resized, that could explain why there are performance issues.


    I hope you find this useful.
