included in the current document. By this I mean that it uses the prefetch logic on things like images, css, and jscript that are being loaded right away, in addition to anchor links which might be
clicked on at a slightly later time."

I'm excited by HTML5's video tag as are plenty of other people. Once that
comes about and once media fragments are adopted, linking to or embedding a portion of a video will be as easy as using the correct
fragment on your URL thanks to the Media Fragments WG who has been hard at work since the last time I looked at fragments.
However, until that work is embraced by browsers, embedding portions of videos will continue to require work specific to the site from which you are embedding the video. On the YouTube blog they
wrote about how to "link to the best parts in your videos", using a fragment syntax like '#t=1m15s' to start playback of the associated
video at 1 minute and 15 seconds. Of course if you want to embed part of a Hulu video it will be different. Although I haven't found an authoritative source describing the URL syntax to use, you
can follow Hulu's video guide on linking to part of a video and note how the URL changes as you adjust the
slider on the time-line. It looks like their syntax for linking to a Hulu page is to add '?c=[start time in seconds](:[end time in seconds])' with the colon and end time optional in order to link
to a portion of a video. And the syntax for embedding appears to be "http://www.hulu.com/embed/.../[start time in seconds](/[end time in
seconds])" again with the end time optional.
For more sites, check out the Media Fragments WG's list of existing applications' proprietary fragmenting
schemes.

I watched the new Star Trek movie Thursday morning, along with many others who work on Windows. Microsoft rented out a theater and played the movie on all screens. I greatly enjoyed the movie!
Spoilers follow... I'm obviously not the biggest Star Trek nerd (or at least TOS nerd) since I didn't even pick up on the fact that Kirk's dad being dead was a discrepancy from the TV series. I
only figured out the alternate time-line stuff when they killed most of the Vulcans. I was just surprised they didn't set right what once went wrong by the end of the movie with some more time
travel magic to bring back Vulcan. On that note, I'm pretty sure the Spock-Spock conversation at the end, is Nimoy Spock sending Sylar Spock off to school so that Nimoy Spock can get freaky
repopulating the Vulcan race. Although at first after his 'two places at once' comment I thought he was saying... something else. Also, was the main evil guy a random miner turned psycho? And his
crazy looking spaceship that destroys the Federation fleet was just a mining vessel from the future? Once they invent time travel anybody can get drunk, go back in time, and conquer Earth.

We've recently put together a working bulbdial clock, with an implementation somewhat different from that of the original concept."

This past week I finished Anathem and despite the intimidating physical size of the book (difficult to take and read on the bus) I became very engrossed and was able to finish it in several orders of
magnitude less time than
what I spent on the Baroque
Cycle. Whereas reading the Baroque Cycle you can imagine Neal Stephenson sifting through giant economic tomes (or at least that's where my mind went whenever the characters began to explain
macro-economics to one another), in Anathem you can see Neal Stephenson staying up late
pouring over philosophy of mathematics. When not
exploring philosophy, Anathem has an appropriate amount of humor, love interests, nuclear bombs, etc. as you might hope from reading Snow Crash or Diamond Age. I thoroughly enjoyed Anathem.
On the topic of made up words: I get made up words for made up things, but there's already a name for cell-phone in English: its "cell-phone". The narrator notes that the book has been translated
into English so I guess I'll blame the fictional translator. Anyway, I wasn't bothered by the made up words nearly as much as some folk. Its a good thing I'm long
out of college because I can easily imagine confusing the names of actual concepts and people with those from the book, like Hemn space for Hamming distance. Towards the beginning, the description
of slines and the post-post-apocalyptic setting reminded me briefly of Idiocracy.
Recently, I've been reading everything of Charles Stross that I can, including about a month ago, The Jennifer Morgue from the surprisingly awesome amalgamation genre of spy thriller and Lovecraft
horror. Its the second in a series set in a universe in which magic exists as a form of mathematics and follows Bob Howard programmer/hacker, cube dweller, and begrudging spy who works for a
government agency tasked to suppress this knowledge and protect the world from its use. For a taste, try a short story from the series that's freely available on Tor's website, Down on the Farm.
Coincidentally, both Anathem and the Bob Howard series take an interest in the world of Platonic ideals. In the case of Anathem (without spoiling anything) the universe of Platonic ideals, under a
different name of course, is debated by the characters to be either just a concept or an actual separate universe and later becomes the underpinning of major events in the book. In the Bob Howard
series, magic is applied mathematics that through particular proofs or computations awakens/disturbs/provokes unnamed horrors in the universe of Platonic ideals to produce some desired effect in
Bob's universe.

I'm a big fan of the concept of registerProtocolHandler in HTML 5 and in FireFox 3, but not quite the implementation. From a high level, it allows web apps to register themselves as
handlers of an URL scheme so for (the canonical) example, GMail can register for the mailto URL scheme. I like the concept:
- Better integration of web apps with your system.
- Its easy for web apps to do.
- Links to URNs can now take the user to the sites the user prefers for the sort of thing identified by the URN. For example, if I have a physical address in HTML, instead of making that an http
link to Yahoo Maps, I can make the link a geo scheme URI and those who follow the link will get their preferred mapping site that
has registered for that scheme. Actually, looking at the geo scheme's RFC, maybe I'd rather use some other URN scheme to represent the physical location, but you get the point.
However, the way its currently spec'ed out I don't like the following:
- There's no way to know if you are the handler for a particular URL scheme which is an important question for web app URL protocol handler authors.
- There's no way to fallback to an http URL in the case that a particular URL scheme isn't registered. A suggested solution to testing the registration of a scheme is for browsers to provide an additional script method
to check if a scheme is registered. I don't like the idea of writing script that walks over all my page's links and rewrites them based on that method. I'd much rather see a declarative and
backwards compatible fallback mechanism, although I don't know what that would look like.
- There's no way to register for a namespace within the urn scheme URI, the info scheme URI, or the tag scheme URI. I want to register
info:lccn/... (Library of Congress Card Number identifiers) to LibraryThing or Amazon and I want to register urn:duri:... (dated URIs) to the Web Archive, among other things.
- Will this result in a proliferation of unregistered URL schemes with clashing namespaces? The ESW Wiki notes why this would be bad.
- And last, although this is nitpickier than the rest, I don't like the '%s' syntax used in the registration method. I'd much rather pass in an URL template, like the URL template used
in OpenSearch. If an URL template is used for matching rather than registering against a particular URL scheme, this could also allow for registering a namespace within a URN. For example
something along the lines of:
registerProtocolHandler("info:lccn/{lccnID}", "htttp://www.librarything.com/search_works.php?q={lccnID}", "LibraryThing LCCN")

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
control panel.
