Sprint fed customer GPS data to cops over 8 million times

2009 Dec 1, 9:40Wow: 'The fact that federal, state, and local law enforcement can obtain communications "metadata"—URLs of sites visited, e-mail message headers, numbers dialed, GPS locations, etc.—without any real oversight or reporting requirements should be shocking, but it isn't. The courts ruled in 2005 that law enforcement doesn't need to show probable cause to obtain your physical location via the cell phone grid. All of the aforementioned metadata can be accessed with an easy-to-obtain pen register/trap & trace order. But given the volume of requests, it's hard to imagine that the courts are involved in all of these.'PermalinkCommentsprivacy security gps phone cellphone government politics

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

Tag Metadata in Feeds

2008 Aug 25, 10:13

As noted previously, my page consists of the aggregation of my various feeds and in working on that code recently it was again brought to my attention that everyone has different ways of representing tag metadata in feeds. I made up a list of how my various feed sources represent tags and list that data here so that it might help others in the future.

Tag markup from various sources
Source Feed Type Tag Markup Scheme One Tag Per Element Tag Scheme URI Human / Machine Names Example Markup

Kids in the Hall Live in Seattle

2008 May 17, 7:58

Sarah and I saw the Kids in the Hall "Live As We'll Ever Be" Tour in the WaMu theater in Seattle this past Thursday. I'd only ever seen their television show so it was cool to see them live. I thought that them being in a live format on stage would make the show significantly different, but other than having a bad seat and not being able to see very well, and the Kids sometimes ad-libbing or breaking character, it was like watching their show. It consisted of mostly new material with some returning characters like the Chicken Lady, Buddy Cole, the head crusher, etc. Their Facebook page has two videos that they played during the show.

I've been using the best Kids in the Hall fansite with an archive of searchable transcripts since high school. But now days what with all the new fangled video websites I can link right to some of my favorite sketches from the show. Like the Inexperienced Cannibal.


And the meta-sketch The Raise.
