NetFlix Media Center and Ong-Bak

2008 Jun 15, 7:57

I just installed vmcNetFlix which lets you watch your on demand NetFlix movies via your Vista Media Center or any Media Center Extenders like the Xbox 360. It works well but fails poorly with some cryptic error messages and long timeouts. Be sure to get NetFlix on demand movies working in your browser before installing this plugin. Once I did that everything worked very well.

To test it out I watched Ong-Bak: The Thai Warrior in which Ting must travel from his country village to Bangkok where he works with his cousin in the city to recover his village's stolen religious artifact. Its a mix of Perfect Strangers, Street Fighter and Pad-See Ew. Martial arts movies, like porn and video games, aren't required to have a strong plot but Ong-Bak has a fine plot line and enjoyable Thai martial arts. I saw the Tiger Knee in there several times. An enjoyable movie that reminded me of watching martial arts movies with my friends in high school.

Generating N-D Tetris Pieces

2008 Jun 1, 7:27

When I woke up this morning for some reason I was thinking about Polytope Tetris, my N-D Tetris game, and specifically generating Tetris pieces in various number of dimensions. When I first wrote PTT I thought that as the number of dimensions increased you could end up with an infinite number of non-equivalent crazy Tetris pieces. However this morning I realized that because you only get four blocks per piece there are only a possible three joints in a single Tetris piece which means that you only need three dimensions to represent all possible distinct N-D Tetris pieces.

Below is the table of the various possible pieces per number of dimensions and sorted by the number of joints in the piece. Notice that the 'J' and 'L' become equivalent in 3D because you can rotate the 'J' through the third dimension to make it an 'L'. The same happens for 'S' and 'Z' in 3D, and 'S+' and 'Z+' in 4D.

Joints	Name	1D	2D	3D	+
1	I
2	J
	L
3	O
	T
	S
	Z
	T+
	S+
	Z+
	Total	1	7	8	7

As a consequence of not realizing there's a finite and small number of N-D Tetris pieces, I wrote code that would randomly generate pieces for a specified number of dimensions by wandering through Tetris space. This consists of first marking the current spot, then randomly picking a direction (a dimension and either forward or backward), going in that direction until hitting a previously unvisited spot and repeating until four spots are marked, forming a Tetris piece. However this morning I realized that continuing in the same direction until reaching am unvisited spot means I can't generate the 'T+' piece. I think the better way to go is keep the list of all possible pieces, pick one randomly, and rotate it randomly through the available dimensions. Doing this will also allow me to give distinct pieces their own specific color (like the classic Tetris games do) rather than picking the color randomly like I do now.

Leaking Information Through Delicious

2008 May 18, 6:45

While re-reading Cryptonomicon I thought about what kind of information I'm leaking by posting links on Delicious. At work I don't post any Intranet websites for fear of revealing anything but I wondered if not posting would reveal anything. For instance, if I'm particularly busy at work might I post less indicating something about the state of the things I work on? I got an archive of my Delicious posts via the Delicious API and then ran it through a tool I made to create a couple of tables which I've graphed on Many Eyes

I've graphed my posts per week and with red lines I've marked IE7 and IE8 releases as stated by Wikipedia. As you can see, there doesn't seem to be much of a pattern so I suppose my concerns we're unfounded. I use it for both work and non-work purposes and my use of Delicious isn't that consistent so I don't think it would be easy to find a pattern like I was thinking about. Perhaps if many people from my project used Delicious and that data could be compared together it might be easier. For fun I looked at my posts per day of week which starts off strong on Mondays and decreases as the week goes on, and my posts per hour of day. It looks like I mostly post around lunch and on the extremes I've only posted very late at night twice at 4am: converting media for the Zune, and Penn's archive of articles. In the morning at 7am I've posted only once: document introducing SGML.manyeyes graph cryptonomicon delicious

Visiting College Friends and Vice Versa

2008 Apr 27, 4:51

Last weekend after Saul and Ciera's wedding, I drove up to Pat, Grib, and Jesse's house to which I hadn't previously been. I got in late and they'd just finished a UFC party. The next day Grib had to travel for work but the rest of us met Scott and Nicole, Jesse's girlfriend at a place for breakfast. After that we went back to their place for some Rock Band which I hadn't played previously and Pat took the opportunity to show off his real life musical skills on the banjo.

This weekend, Jesse and Nicole are up visiting Seattle. On Friday, Sarah and I met up with them at the BluWater Bistro in Seattle which sits right on Lake Union. The view was nice although difficult to see from our table and overall I like the sister restaurant in Kirkland better. They were both short visits but it was fun to see people again.
