Windows Media Center and Zune Integration Hack

2007 Nov 28, 1:23One of the new Zune features that had me the most excited was the claimed improved Windows Media Center integration which unfortunately turned out to simply mean support for the Win MCE video format (with an exception for HD). I wanted to be able to pick shows recorded by my Win MCE and have the Zune automatically sync up the latest episodes. However, with the improved podcast support in the Zune software one can easily create a ridiculous hack to accomplish this.

The new Zune software has podcast support which does everything I'd want to do with a Win MCE recorded TV series so the goal is to shoehorn a TV series into a Zune podcast. An overview of the steps: Create an XSLT that converts Win MCE data to a podcast, run the XSLT as a scheduled task every few hours per TV series, setup a Web server pointed at the resulting podcasts and the Win MCE Recorded TV directory, and subscribe to the resulting podcasts in the Zune software.
  1. Reading through the Win MCE data stored as an XML file in "C:\ProgramData\Microsoft\eHome\Recording\Recordings.xml" and the spec for podcasts I created an XSLT to convert a series from Win MCE data to a podcast.
  2. I added a new task to the Scheduled Tasks to run my XSLT using my xsltproc.js script. The task runs a handful of commands that look something like the following:

    C:\windows\system32\wscript.exe C:\users\dave\bin\xsltproc.js C:\Users\Dave\Documents\trunk\development\mce-zune\mce-to-podcast.xslt C:\ProgramData\Microsoft\eHome\Recording\Recordings.xml --param title "The Daily Show With Jon Stewart" --param max 4 --param baseURI "http://groucho/" --param thisRelURI "tds.xml" -o "D:\recorded tv\tds.xml"

    For each TV series I run a command like the above and that outputs a podcast for that series into my "D:\Recorded TV\" directory.
  3. Zune only allows http URIs for its podcasts so I installed a web server on my Win MCE server. I'm running Vista Ultimate so it was quick and easy for me to install IIS7 but any Web server will do. Then I pointed it at "D:\Recorded TV\".
  4. Once all the above was done I just subscribed to the resulting podcasts via my Web server and viola! Since I'm forced to use a Web server I can even run the Zune software on a machine other than my Win MCE server. You can see a screen-shot above of my Zune software showing my Colbert Report podcast.

Vishu and Patent Cube

2007 Nov 28, 5:07Vishu, my ex-office-mate, has left Washington and Microsoft for California and Facebook. Vishu and I shared an office for a while and I really enjoyed it. We were able to distract one another from, and help each other with work. We'd often bounce ideas off of one another, work related or otherwise. For one such idea I recently received a Microsoft patent cube, a small marble cube inscribed with my and my invention's name. There are some photos of other people's patent cubes on flickr. Vishu would have received one for this idea too since we developed the idea and wrote the document about it together, but they wait a long time to send you the cube and he was gone a few weeks before they sent it (don't worry, he got the credit and other rewards though).

A week or two after I got my cube Vishu was visiting the Microsoft campus just before moving his family down with him to California. A bunch of us joined him for lunch that day and it sounds like he's enjoying his new job already. Have fun Vishu!PermalinkCommentsmicrosoft facebook vishu cube patent nontechnical

Portal is fun; the cake is a lie!

2007 Oct 22, 4:47I purchased the Orange Box off of Steam a bit ago and like others before me who have discussed elsewhere, I already owned two of the five games that come from the Orange Box. However, the combined price of HL2E2 and Portal, the two games I actually wanted was supposedly equivalent to the price of the Orange Box bundle. Incidentally, if anyone would like HL2 or HL2E1 I can gift them to you.

HL2E2 was excellent of course but the big surprise for me was Portal. (Mild spoilers follow) It has a sort of zen simplicity: there are a few simple game-play mechanics, a handful of textures and objects, and a deceptively simple story all used well and tied together to produce an entertaining and polished game. It seems a bit short but its probably better to end with the gamer demanding more. The humor and the sort of play within a play aspect of the game is what really sold me though. It has the funniest ending theme I've heard (also blogged by the creator). The voices of the automated turrets are so adorable I would feel compelled to hug them if they weren't always trying to kill me. Additionally the weighted companion cube seems like an experiment in understanding gamers' attachment to NPCs. In this case the NPC is a box and yet I still felt awful incinerating it. The whole time I was vaguely reminded of Solitary the reality show that sticks contestants alone in small rooms forcing them to endure various tests all the while being watched by a humorous computer with a female voice. Someone should sue...

RPS has articles on Portal including a Portal review, a page suggesting Portal is a tale of lesbianism, and others.PermalinkCommentshl2e2 game hl2 solitary valve portal nontechnical

FoaF on my Homepage

2007 Oct 14, 3:12I've updated my homepage by moving stuff about me onto a separate About page. Creating the About page was the perfect opportunity to get FoaF, a machine readable way of describing yourself and your friends, off my to do list. I have a base FoaF file to which I add friends, projects, and accounts from delicious using an XSLT. This produces the FoaF XML resource on which I use another XSLT to convert into HTML and produce the About page.

I should also mention a few FoaF pages I found useful in doing this: PermalinkCommentstechnical xml foaf personal xslt xsl homepage

XSL Transforms in JavaScript

2007 Oct 7, 4:12In a previous post I mentioned an xsltproc like js file I made. As noted in that post, on Windows you can write console script files in JavaScript, name them foo.js, and execute them from the command prompt. I later found that MSDN has an XSLT javascript sample which looks similar to mine, but I like mine better for the XSLT parameter support and having a non-ridiculous way of interpreting filenames. The code for my xsltproc.js follows. The script is very simple and demonstrates the ease with which you can manipulate these system objects and all it takes is opening up notepad.
var createNewXMLObj = function() {
   var result = new ActiveXObject("MSXML2.FreeThreadedDOMDocument");
   result.validateOnParse = false;
   result.async = false;
   return result;
}

var args = WScript.arguments;
var ofs = WScript.CreateObject("Scripting.FileSystemObject");

var xslParams = [];
var xmlStyle = null;
var xmlInput = null;
var inputFile = null;
var outputFile = null;
var error = false;

for (var idx = 0; idx < args.length && !error; ++idx)
   if (args.item(idx) == "-o") {
      if (idx + 1 < args.length) {
         outputFile = ofs.GetAbsolutePathName(args.item(idx + 1));
         ++idx;
      }
      else
         error = true;
   }
   else if (args.item(idx) == "--param" || args.item(idx) == "-param") {
      if (idx + 2 < args.length) {
         xslParams[args.item(idx + 1)] = args.item(idx + 2);
         idx += 2;
      }
      else
         error = true;
   }
   else if (xmlStyle == null) {
      xmlStyle = createNewXMLObj();
      xmlStyle.load(ofs.GetAbsolutePathName(args.item(idx)));
   }
   else if (xmlInput == null) {
      inputFile = ofs.GetAbsolutePathName(args.item(idx));
      xmlInput = createNewXMLObj();
      xmlInput.load(inputFile);
   }

if (xmlStyle == null || xmlInput == null || error) {
   WScript.Echo('Usage:\n\t"xsltproc" xsl-stylesheet input-file\n\t\t["-o" output-file] *["--param" name value]');
}
else {
   var xslt = new ActiveXObject("MSXML2.XSLTemplate.3.0");
   xslt.stylesheet = xmlStyle;
   var xslProc = xslt.createProcessor();
   xslProc.input = xmlInput;

   for (var keyVar in xslParams)
      xslProc.addParameter(keyVar, xslParams[keyVar]);

   xslProc.transform();

   if (outputFile == null)
      WScript.Echo(xslProc.output);
   else {
      var xmlOutput = createNewXMLObj();

Date Time Formats

2007 Sep 27, 2:17Starting on a new simple project I wanted to get the history of my Delicious links. Delicious has an export tool available via the settings section so I thought I'd try that. However, the links aren't exported in XML not even in XHTML but rather in HTML. Shocking. An example:
"Don't Tase Me, Bro!" (UF Student Tasered Remix)
Remix of the 'Don't tase me, bro!' guy getting tasered.At this point I'm already not going to use this file because its in HTML but I'm even more disgusted by those date time values. Raymond Chen of the Old New Thing posted about recognizing timestamps and timestamp sentinel values. From the first blog post and with the use of a calculator for base conversion one can tell that those are UNIX style timestamps counting the number of seconds since 1970.

It reminds me of my hatred for the MIME date time format I developed working on my webpage's server side parsing of atom and RSS. Atom is of course my favorite as Atom uses the Internet date time format described in the following documents. Here's an example of one 2007-09-27T020:50:00.000-08:00 On the other hand the evil and villainous RSS uses the MIME date time format now described in the more recent IETF MIME standard. Here's an example Thu, 27 Sep 2007 20:50:00 -0800
The Internet date time format has the advantage of being so easy to sort. An alphabetic sort with normal C-style collation rules of strings containing Internet date times will also sort them chronologically. This is not the case for the MIME date time due to the preceding day of the week and the spelled out month name. This also means that when producing these you have to figure out the day of the week and when parsing them you have to match month names rather than just parsing out numbers. Anyway now days if I see mention of a date time in a new proposed standard or spec I be sure to point out the numerous advantages of the Internet date time format.

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

Which which - Batch File Hackiness

2007 Aug 9, 5:41To satisfy my hands which have already learned to type *nix commands I like to install Win32 versions of common GNU utilities. Unfortunately, the which command is a rather literal port and requires you to enter the entire name of the command for which you're looking. That is 'which which' won't find itself but 'which which.exe' will. This makes this almost useless for me so I thought to write my own as a batch file. I had learned about a few goodies available in cmd.exe that I thought would make this an easy task. It turned out to be more difficult than I thought.

for /F "usebackq tokens=*" %%a in ( `"echo %PATH:;=& echo %"` ) do (
    for /F "usebackq tokens=*" %%b in ( `"echo %PATHEXT:;=& echo %"` ) do (
        if exist "%%a"\%1%%b (
            for  %%c in ( "%%a"\%1%%b ) do (
                echo %%~fc
            )
        )
    )
)
The environment variables PATH and PATHEXT hold the list of paths to search through to find commands, and the extensions of files that should be run as commands respectively. The 'for /F "usebackq tokens=*" %%a in (...) do (...)' runs the 'do' portion with %%a sequentially taking on the value of every line in the 'in' portion. That's nice, but PATH and PATHEXT don't have their elements on different lines and I don't know of a way to escape a newline character to appear in a batch file. In order to get the PATH and PATHEXT's elements onto different lines I used the %ENV:a=b% syntax which replaces occurrences of a with b in the value of ENV. I replaced the ';' delimiter with the text '& echo ' which means %PATHEXT:;=& echo% evaluates to something like "echo .COM& echo .EXE& echo .BAT& ...". I have to put the whole expression in double quotes in order to escape the '&' for appearing in the batch file. The usebackq and the backwards quotes means that the backquoted string should be replaced with the output of the execution of its content. So in that fashion I'm able to get each element of the env. variable onto new lines. The rest is pretty straight forward.

Also, it supports wildcards:
