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.
So I wrote an XSLT to convert from Flickr Search XML to Visual Suggestions XML and used my xsltproc Meddler script to actually
apply this xslt.
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.

Bulbdial Clock. That's like a sundial, but with better resolution-- not just an hour hand, but a minute and second hand as well, each given as a shadow from moving artificial light sources (bulbs).
We've recently put together a working bulbdial clock, with an implementation somewhat different from that of the original concept."

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!"

the video clip played at its normal speed. If you clapped faster, the video clip ran faster. If you clapped slower, the video clip ran slower. If you stopped clapping, the video clip stopped. It was
freaky cool. Totally useless, but freaky cool."

having to do it all with script. "The HTML5 standard function registerProtocolHandler() should probably remain void as in standard, but WhatWG could invent yet another boolean
protocolRegistered("area"), with the only argument (protocol name as string), to check whether a protocol is registered."

prompt the user to choose which of the registered applications (web or desktop) it should use to handle the action. Any protocol, real or imaginary, can be used - mailto: is only one example,
webcal:, tel: and fax: are others."

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.

for interactions with local content.

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")

Abba are on the charts, the Cold War is in full swing - and the Earth is flat. It's been flat ever since the eve of the Cuban war of 1962; and the constellations overhead are all
