HTML5's mime-sniffing is getting moved to an IETF doc: "Many web servers supply incorrect Content-Type headers with their HTTP responses. In order to be compatible with these servers, user agents
must consider the content of HTTP responses as well as the Content-Type header when determining the effective media type of the response. This document describes an algorithm for determining the
effective media type of HTTP responses that balances security and compatibility considerations."

The HTML5 spec tells us how it is in the real world for URLs: "This specification defines various algorithms for dealing with Web addresses intended for use by HTML user agents. For historical
reaons, in order to be compatible with existing Web content HTML user agents need to implement a number of processes not defined by the URI and IRI specifications [RFC3986], [RFC3987]."

I've made another extension for IE8,
Outline View, which gives you a side bar in IE that displays an outline of the current page and lets you make intrapage bookmarks.
The outline is generated based on the heading tags in the document (e.g. h1, h2, etc), kind of like what W3C's Semantic data extractor
tool displays for an outline. So if the page doesn't use heading tags the way the HTML spec intended or just sticks img tags in them, then the outline doesn't look so hot. On a page that does
use headings as intended though it looks really good. For instance a section from the HTML 4 spec shows up quite nicely and I find its
actually useful to be able to jump around to the different sections. Actually, I've been surprised going to various blogs how well the outline view is actually working -- I thought a lot more
webdevs would be abusing their heading tags.
I've also added intrapage bookmarks. When you make a text selection and clear it, that selected text is added as a temporary intrapage bookmark which shows up in the correct place in the outline.
You can navigate to the bookmark or right click to make it permanent. Right now I'm storing the permanent intrapage bookmarks in IE8's new per-domain DOM storage because I wanted to avoid writing
code to synchronize a cross process store of bookmarks, it allowed me to play with the DOM storage a bit, and the bookmarks will get cleared appropriately when the user clears their history via the

In my Intro to Algorithms course in college the Fibonacci sequence was used as the example algorithm to which various types of algorithm creation methods were applied. As the course went on we made
better and better performing algorithms to find the nth Fibonacci number. In another course we were told about a matrix that when multiplied successively produced Fibonacci numbers. In my linear
algebra courses I realized I could diagonalize the matrix to find a non-recursive Fibonacci function. To my surprise this worked and I
found a function.
Looking online I found that of course this same function was already well known. Mostly I was irritated that after all the
algorithms we created for faster and faster Fibonacci functions we were never told about a constant time function like this.
I recently found my paper depicting this and thought it would be a good thing to use to try out MathML, a markup language for
displaying math. I went to the MathML implementations page and installed a plugin for IE to display MathML and then began writing up my paper in
MathML. I wrote the MathML by hand and must say that's not how its intended to be created. The language is very verbose and it took me a long time to get the page of equations transcribed.
MathML has presentation elements and content elements that can be used separately or together. I stuck to content elements and while it looked great in IE with my extension when I tried it in
FireFox which has builtin MathML support it didn't render. As it turns out FireFox doesn't support MathML content elements. I had already finished creating this page by hand and wasn't about to
switch to content elements. Also, in order to get IE to render a MathML document, the document needs directives at the top for specific IE extensions which is a pain. Thankfully, the W3C has a
MathML cross platform stylesheet. You just include this XSL at the top of your XHTML page and it turns content elements into appropriate
presentation elements, and inserts all the known IE extension goo required for you. So now my page can look lovely and all the ickiness to get it to render is contained in the W3C's XSL.
