Thoughts on registerProtocolHandler in HTML 5

2009 Apr 7, 9:02

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:

However, the way its currently spec'ed out I don't like the following: PermalinkCommentsurl template registerprotocolhandler firefox technical url scheme protocol boring html5 uri urn

Official Google Webmaster Central Blog: Specify your canonical

2009 Feb 14, 5:41"Now, you can simply add this link tag to specify your preferred version... and Google will understand that the duplicates all refer to the canonical URL: http://www.example.com/product.php?item=swedish-fish. Additional URL properties, like PageRank and related signals, are transferred as well."PermalinkCommentsvia:mattb google link html url uri canonical canonicalization web

Wikipedia Tools

2007 Sep 12, 6:54I'm visiting Wikipedia more and more recently but I always find myself reading the referenced webpages to get the full context of quotes and for more info. Basically I use Wikipedia as an introduction and a place to look for links. For times when I'm looking for opinions rather than facts I like to use Everything2. No need to check references there.

There's the much hyped WikiScanner tool which reports who has been making anonymous (thought to be anonymous at the time anyway) edits to Wikipedia. Its humorous and interesting in a few cases, but in general I think its stretching to say that because an IP address range is owned by a corporation and someone edited Wikipedia on an IP in that range that you can attribute that edit to that corporation. If I edited Wikipedia I'd probably do a bit of that during my lunch break, but that wouldn't mean that Microsoft wants the Wikipedia pages for Weird Al, Dave Risney, URIs, or whatever else I would edit on Wikipedia changed.

Also, via Everything Is Miscellaneous I found the tool Wiki Dashboard. Wiki Dashboard proxies Wikipedia and on each page shows a timeline view at the top with who made edits and when. Its nice to see a gentle curve down from an initial spike at the beginning for topics you don't imagine to be controversial. As the canonical test page for this service I looked up 'Elephant' the Wikipedia page Stephen Colbert suggested folks vandalize on his show on 2006 July 31st. If you look at the Wiki Dashboard Elephant page you can see a very large spike in edits on that date. That's all I need to see.

As a side note, for the link on Stephen Colbert suggesting folks vandalize Wikipedia I linked to a Wikipedia article. Is it inappropriate to provide info about Wikipedia being vandalized and thus incorrect via a link to a Wikipedia article?PermalinkCommentswikidashboard stephen-colbert wikality wikipedia wikiscanner colbert-report

OpenID Stolen Thoughts

2007 Mar 13, 7:57I had a few thoughts after reading about OpenID. However, after doing only a very small amount of digging I can see these aren't new thoughts.
Anonymous OpenID
Have an OpenID that anyone can use because it performs no authorization. You'd specify a URI like http://deletethis.net/anonymousopenid/yournamehere and you'd immediately get an anonymous OpenID associated with that URI. This has already been implemented by Jayant Gandhi.
Group OpenID
Have an OpenID that consists of a group of member OpenIDs. To login as the Group OpenID you need to login with any of the member OpenIDs. This is discussed more by Dmitry Shechtman on his blog.
OpenID Normalization
I find that I already have a couple of OpenIDs without even trying due to AOL giving out OpenIDs. I'd like for all of my OpenIDs to point to one canonical OpenID. It looks like this may already be possible by the OpenID specification.
I guess I'm a little late to the scene.PermalinkCommentstechnical stolen-thoughts openid
