DVD Ripping and Viewing in Windows Media Center

2010 Aug 17, 3:05

I've just got a new media center PC connected directly to my television with lots of HD space and so I'm ripping a bunch of my DVDs to the PC so I don't have to fuss with the physical media. I'm ripping with DVD Rip, viewing the results in Windows 7's Windows Media Center after turning on the WMC DVD Library, and using a powershell script I wrote to copy over cover art and metadata.

My powershell script follows. To use it you must do the following:

  1. Run Windows Media Center with the DVD in the drive and view the disc's metadata info.
  2. Rip each DVD to its own subdirectory of a common directory.
  3. The name of the subdirectory to which the DVD is ripped must have the same name as the DVD name in the metadata. An exception to this are characters that aren't allowed in Windows paths (e.g. <, >, ?, *, etc)
  4. Run the script and pass the path to the common directory containing the DVD rips as the first parameter.
Running WMC and viewing the DVD's metadata forces WMC to copy the metadata off the Internet and cache it locally. After playing with Fiddler and reading this blog post on WMC metadata I made the following script that copies metadata and cover art from the WMC cache to the corresponding DVD rip directory.

Installable Web Apps - Google Code

2010 May 24, 6:29Installable web apps makes total sense given the Google Chrome OS: "An installable web app is a normal web site with a bit of extra metadata. You build and deploy this app exactly as you would build and deploy any web app, using any server-side or client-side technologies you like. The only thing that is different about an installable web app is how the app is packaged."PermalinkCommentstechnical web browser webapp google chrome

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

Composing the Semantic Web: Units ontology with SPIN support published

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
