To Flash or not to Flash this is the question…

Looks like a tsunami of change again for Multimedia.

  • Flash CS5
  • Microsoft Visual studio/Silverlight
  • HTML5/CSS3/JavaScript?

With Steve Jobs firing a major salvo across Adobes bows:

(Thanks Steph)

I’m going to have to think about how we will deliver multimedia in the future.


Using JavaScript to increase browser text size

Leave a comment

When I display my wiki on an overhead in class it is useful to increase the text size. At present I have to use page>Text Size> Larger. Using my “friend” Dr. Google (he/she?) who knows much more than me, came up with a solution by David Walsh ( a Sun Developer) There are lots of very tricky solutions out there including those that restyle every individual tag on the page. Note however the resize is only active on the current page (as its JavaScript) so if you go to another page you will have to resize again, unlike the Browser setting which persists.

Am looking to implement this in soon.

Firefox extensions xpi error

Leave a comment

Have been toying with developing an extension for firefox and uploaded the file to my brinkster account.

Trying to create a web based install using the Javascript code I created a xpi file and the JavaScript. (The xpi file is just a zip file renamed). Trying to install into my firefox gave a -223 error (I think that was it).

so…trying to isolate the error….

When I upload as a .zip I can download via my web page, but when I either upload as a zip or upload as a zip and rename the file it will not download correctly.

Download the xpi file then rename as zip. Then opening gives a file corrupt error.

One possible suggestion  ( was
You are using Microsoft IIS as your webserver, but the MIME type (also called “Content-type”, or “Internet Media type”) for XPI files has not been added to your IIS configuration.

To fix this problem, add the following to your IIS MIME types configuration:

Extension:      .xpi
Mime Type:      application/x-xpinstall

Brinkster added this to their IIS server and all is sweet now.

So, now onto adding some JavaScript to my extension :)

Creating a Firefox add-in

Leave a comment

I’m playing around creating a Firefox add-in (as well as looking into an IE plug-in). These pages describe how to do it (it shows how you can use Visual Studio to help). Lots of ads which is a bit annoying but shows how it is done.
