2009 May 22, 6:37Famous people are just like me! That is, Jorge Garcia (Hurley from Lost) also has a blog on which he writes about and posts pictures of his visit to the Neuschhwanstein Castle in Munich (the basis of
the Disney castle). But apparently unlike me he didn't take the Bus of the Year 2005 to get to the castle.via:kottkehurleylosttvbloggermanyfor:hellosarah
Netflix lets you watch a subset of their movies online via their website and a subset of those movies are available to watch on the Xbox 360's Netflix app. so its not always easy to find movies to
watch on Xbox 360. Yet, I regularly see my Xbox friends using the Netflix app and its a shame they didn't make an easy way to share movie recommendations with your friends. Instead we must share
movie recommendations the old fashioned way. Here's the movies I've found and enjoyed on my 360.
If you enjoyed Paranoia Agent you'll enjoy this movie in the same animation style and by the same director and
writer, Satoshi Kon. Its like a feature length version of a Paranoia Agent episode in which a dream machine lets outsiders view one's dreams but eventually leads to blurring the dreams and
reality.
I didn't see either of the Grindhouse movies when they first came out, but of the two, Planet Terror is the more humorous and exciting gore filled parody.
A hilarious documentary on the struggle between the reigning champ hot-sauce salesman and the underdog Washington state high school science teacher to obtain the Donkey Kong world record high
score. After watching, checkout this interview with the creators of the movie and the
villain.

developers seem insistent on using XML in ways which seem convenient for a moment but which cause much greater trouble down the line to both their projects and to markup itself."xmlhowtotips
After getting this all working I've placed the result in two places: (1) I've updated the xsltproc Meddler script to include this XSLT and an
XML file to install it as a search provider - although you'll need to edit the XML to include your own Flickr API key. (2) I've created a service for this so you can just install the Flickr search provider if you're interested in having the functionality and don't care about the implementation. Additionally, to the
search provider I've added accelerator preview support to show the Flickr slideshow which I think looks snazzy.
Doing a quick search for this it looks like there's at least one other such implementation, but mine has the distinction of being done through XSLT which I provide, updated XML namespaces to work
with the released version of IE8, and I made it so you know its good.
There can be no doubt that infomercial pitchmen Billy Mays and Vince Offer are awesome,
but how can I decide which is my favorite?
Infomercial Performance.
Among other things they sell Zorbeez and ShamWow respectively, both of which are absorbant towels so first up I can get a somewhat apples-to-apples comparison on informercials for comparable
products. Thankfully someone has created a Vince Offer vs Billy Mays youtube video featuring these informercials.
Billy has an upbeat yell to everything he says while Vince has an endearing condescension to his "You followin' me camera guy?" In the end I must give this one to Vince Offer.
Billy has challenged Vince to a pitchman-off which on the surface sounds like a point for Billy, but if you listen to the challenge Billy says that Vince attempted to extend the olive branch.

2009 Apr 7, 1:30I really dislike how IE deals with non-US-ASCII in URLs. I should write up a post on what exactly IE does with non-US-ASCII characters in URLs. "Just like IRIs the URL is mapped to a URI using UTF-8.
Except for the query component of the URL (the bit after the question mark). Here for legacy reasons the encoding of the document is used instead. Except if the encoding of the document is UTF-16, in
which case UTF-8 is used. Effectively, using non-ASCII characters in URLs in documents not encoded as UTF-8 or UTF-16 will give you surprising results, to say the least. Yay for browsers!"httpencodinghtml5urluriunicodeiri
2009 Apr 7, 12:12HTML5's registerProtocolHandler seems to come from a cool FireFox 3 feature: "With web protocol handlers, the web application can register the specific protocol it wants to handle. Firefox will then

webcal:, tel: and fax: are others."firefoxurischemeprotocolmozillahtml5registerProtocolHandler
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.
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.
Working on Internet Explorer extensions in C++ & COM, I had to relearn or rediscover how to do several totally basic and important things. To save myself and possibly others trouble in the
future, here's some pertinent links and tips.
First you must choose your IE extensibility point. Here's a very short list of the few I've used:
Once you've created your COM object that implements IObjectWithSite and whatever other interfaces your extensibility point requires as described in the above links you'll see your SetSite method
get called by IE. You might want to know how to get the top level browser object from the IUnknown site object passed in via that method.
After that you may also want to listen for some events from the browser. To do this you'll need to:
Implement the dispinterface that has the event you want. For instance DWebBrowserEvents2, or HTMLDocumentEvents, or HTMLWindowEvents2. You'll have
to search around in that area of the documentation to find the event you're looking for.
Register for events using AtlAdvise. The object you need to subscribe to depends on the events you want. For example, DWebBrowserEvents2 come from the webbrowser object, HTMLDocumentEvents come
from the document object assuming its an HTML document (I obtained via get_Document method on the webbrowser), and
HTMLWindowEvents2 come from the window object (which oddly I obtained via calling the get_script method on the document object).
Note that depending on when your SetSite method is called the document may not exist yet. For my extension I signed up for browser events immediately and then listened for events like NavigateComplete before signing up for document and window events.
Implement IDispatch. The Invoke method will get called with event notifications from the dispinterfaces you sign up for in AtlAdvise. Implementing Invoke manually is a slight pain as all the
parameters come in as VARIANTs and are in reverse order. There's some ATL macros that may make this easier but I didn't bother.
Call AtlUnadvise at some point -- at the latest when SetSite is called again and your site object changes.
If you want to check if an IHTMLElement is not visible on screen due how the page is scrolled, try comparing the Body or
Document Element'sclient height and width,
which appears to be the dimensions of the visible document area, to the element's bounding client rect which appears to be
its position relative to the upper left corner of the visible document area. I've found this to be working for me so far, but I'm not positive that frames, iframes, zooming, editable document
areas, etc won't mess this up.
Be sure to use pointers you get from the IWebBrowser/IHTMLDocument/etc. only on the thread on which you obtained the pointer or correctly marshal the pointers to other threads to avoid weird crashes and hangs.
I've made an extension for Internet Explorer 8, FormToAccelerator which turns HTML forms on a web page into either an accelerator or a search
provider. In the design of the accelerators format we intentionally had HTML forms in mind so that it would be easy to create accelerators for existing web services. Consequently, creating an
accelerator from an HTML form is a natural concept and an extension I've been meaning to finish for many months now.
This is similar in concept to the Opera feature that lets you add a form as a search provider. The user experience is very rough and requires some knowledge of accelerator variables. If I can come
up with a better interaction model I may update this in the future, but at the moment all the designs I can come up with require way too much effort. Install IE8 RC1 and then try out FormToAccelerator.

photos then you'd generally get from polling Everyone's photos. The quality is pretty good, the best thing to do is watch The Panda for a while and figure out if a) you want to build something with a
live stream of photos b) you can build something more better than a vomiting panda (which lets face it, it pretty hard to top!)."humorpandaflickrreferenceapiphotos
I've found while debugging networking in IE its often useful to quickly tell if a string is encoded in UTF-8. You can check for the Byte Order Mark (EF BB BF in UTF-8) but, I rarely see the BOM on
UTF-8 strings. Instead I apply a quick and dirty UTF-8 test that takes advantage of the well-formed UTF-8 restrictions.
Unlike other multibyte character encoding forms (see Windows supported character sets or IANA's list of character sets), for example Big5, where sticking together any two bytes is more likely than not to give a valid byte sequence, UTF-8 is more restrictive. And unlike
other multibyte character encodings, UTF-8 bytes may be taken out of context and one can still know that its a single byte character, the starting byte of a three byte sequence, etc.
The full rules for well-formed UTF-8 are a little too complicated for me to commit to memory. Instead I've got my own simpler (this is the quick part) set of rules that will be mostly correct (this
is the dirty part). For as many bytes in the string as you care to examine, check the most significant digit of the byte:
F:
This is byte 1 of a 4 byte encoded codepoint and must be followed by 3 trail bytes.
E:
This is byte 1 of a 3 byte encoded codepoint and must be followed by 2 trail bytes.
C..D:
This is byte 1 of a 2 byte encoded codepoint and must be followed by 1 trail byte.
8..B:
This is a trail byte.
0..7:
This is a single byte encoded codepoint.
The simpler rules can produce false positives in some cases: that is, they'll say a string is UTF-8 when in fact it might not be. But it won't produce false negatives. The following is table
from the Unicode spec. that actually describes well-formed UTF-8.
I knew that the command line tool subst would create virtual drives that map to existing directories but I didn't know that subst lets you name the virtual drives with characters that aren't
US-ASCII letters. For instance you can run 'subst 4: C:\windows' and then 'more 4:\win.ini' to dump C:\windows\win.ini. This also works for non-US-ASCII characters like, "Ｃ" (aka U+FF23, Fullwidth Latin Capital Letter C), which when displayed by cmd.exe via some best fit style character conversions looks just like the regular US-ASCII 'C'. None of Explorer, IE, or the common file
dialogs allow the use of these odd virtual drives -- just cmd.exe, so I'm not sure how this would ever be useful but I thought it was odd and I wanted to share.
A while ago I promised to say how an xsltproc Meddler script would be useful and the general answer is
its useful for hooking up a client application that wants data from the web in a particular XML format and the data is available on the web but in another XML format. The specific case for this
post is a Flickr Search service that includes IE8 Visual Search Suggestions. IE8
wants the Visual Search Suggestions XML format and Flickr gives out search data in their Flickr web API XML format.
