I just upgraded to the Zune 3.0 software which includes games and purchasing music on the Zune via WiFi and once again I'm thrilled that the new firmware is available for old Zunes like mine. Rooting around looking at the new features I noticed Zune Badges for the first time. They're like Xbox Achievements, for example I have a Pixies Silver Artist Power Listener award for listening to the Pixies over 1000 times. I know its ridiculous but I like it, and now I want achievements for everything.
Achievements everywhere would require more developments in self-tracking. Self-trackers, folks who keep statistics on exactly when and what they eat, when and how much they exercise, anything one may track about one's self, were the topic of a Kevin Kelly Quantified Self blog post (also check out Cory Doctorow's SF short story The Things that Make Me Weak and Strange Get Engineered Away featuring a colony of self-trackers). For someone like me with a medium length attention span the data collection needs to be completely automatic or I will lose interest and stop collecting within a week. For instance, Nike iPod shoes that keep track of how many steps the wearer takes. I'll also need software to analyze, display, and share this data on a website like Mycrocosm. I don't want to have to spend extreme amounts of time to create something as wonderful as the Feltron Report (check out his statistic on how many daily measurements he takes for the report). Once we have the data we can give out achievements for everything!

Of course none of the above is practical yet, but how about Delicious achievements based on the public Delicious feeds? That should be doable...
Internet Explorer 8 Beta 2 is now available! Some of the new features from this release that I really enjoy are Tab Grouping, the new address-bar, and InPrivate Subscriptions.
Tab Grouping groups tabs that are opened from the same page. For example, on a Google search results page if you open the first two links the two new tabs will be grouped with the Google search results page. If you close one of the tabs in that group focus goes to another tab in that group. Its small, but I really enjoy this feature and without knowing exactly what I wanted while using IE7 and FF2 I knew I wanted something like this. Plus the colors for the tab groups are pretty!
The new address bar and search box makes life much easier by searching through my browsing history for whatever I'm typing in. Other things are searched besides history but since I ignore favorites and use Delicious I mostly care about history. At any rate its one of the things that makes it impossible for me to go machines running IE7.
InPrivate Subscriptions allows you to subscribe to a feed of URLs from which IE should not download content. This is intended for avoiding sites that track you across websites and could sell or share your personal information, but this feature could be used for anything where the goal is to avoid a set of URLs. For example, phishing, malware sites, ad blocking, etc. etc. I think there's some interesting uses for this feature that we have yet to see.
Anyway, we're another release closer to the final IE8 and I can relax a little more.
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.
Doctor Horrible's Sing Along Blog is an Internet only show you may have already watched and heard everything about. If you missed this somehow, its a musical by Joss Whedon (Buffy the Vampire Slayer, Firefly) staring Neil Patrick Harris as an aspiring super villian who can't get up the courage to talk to his laundromat crush. Its very funny, fairly geeky, and on the Internet so of course I've enjoyed it thoroughly and have some links to share. It surprised me how many blogs that I don't usually see posting the same things telling me about it: first on Eric's blog, then The Old New Thing, and even Penny-Arcade.
Dr. Horrible's again available online via Hulu with commercial interruption.
Check out the official fan site. They link to such things as the owner of Dr. Horrible's house. He had appeared on Monster House, a reality show about remaking people's homes like Monster Car or Pimp My Ride is about remaking folk's cars, and had his house turned into a evil scientist's lab. Consequently its a perfect fit for Dr. Horrible and in return the owner appears in one of the final scenes and in the credits as the 'Purple Pimp'. Apparently the purple suit is his. Also on his blog you can find out what's happened on that big chair that appears in the show. All I'll say about that is, good thing Neil Patrick Harris wears a lab coat while sitting on it.
At the recent Comic Con some attendees took video of the Dr. Horrible Comic Con panel (video clips contain spoilers) some of which I've grouped together. Besides the videos containing the creators and stars of the musical who are all hilarious (see Felicia Day's comment on twittering) there's also some excellent bits about a possible second installment and information on the impending DVD. To finish off this series of Dr. Horrible links check out this Venn Diagram of Felicia Day's work.
I've got a new office and I must clean off my inherited whiteboard. The previous owner left various diagrams, code snippets, etc. on for such a time that they can no longer be erased
by conventional means: the whiteboard eraser is useless! I couldn't find any whiteboard cleaner either, but Ali told me the following secret. You can write over the dried on text with a normal dry
erase marker. When you erase the new markings the old are erased as well. It sounds too fantastic, but believe me, its true! I don't know the brand or material of the whiteboard but the whiteboard
markers are 'Expo, Bold Color Dry Erase'.
