Earplug Alarm Clock

In my previous home, just after I moved in, my neighbor which was the city of Redmond's various city government buildings, decided to build a parking structure. This was maybe 30 feet from my window, lasted for at least a year and would regularly wake me up at seven or eight in the morning. Determined to not be so punctual for work, I got earplugs which meant in addition to not hearing the construction outside, I couldn't hear my alarm. I had an idea for a combination ear plug, headphone, alarm clock that I never did anything with, except to write down the phrase "earplug / headphone / alarm clock" on a list that I just now found. In retrospect, I think this problem might be too specific to result in my earplug alarm clock selling well.

The Wii Fit's Mind Games

Sarah received her Wii Fit a few weeks ago. The Wii Fit is a game for the Wii and a balance board accessory that can tell how you're standing on it: leaning forward, standing on one foot, leaning backward and mostly on your left foot, etc. The game puts you through various exercises grouped into the categories of aerobic, balance, strength, and yoga. It also lets you set goals and keeps track of how well you do, how long you play, and a graph of your weight.

The portion I didn't expect were the mind games. Sarah turned it on after not using it for a day and it said something to the effect of 'Oh, didn't have time to exercise yesterday? Huh. Interesting....' I'm paraphrasing of course but the Wii Fit was definitely trying to lay down some guilt. In another instance when starting up the Wii Fit Sarah was asked 'Did you know that Dave has been using Wii Fit?' She selected yes and it then asked her how she thought I was progressing giving her four options. She selected the worst one, that I was getting worse (jokingly I hope) and it told her to tell me that, but not to use those words. In conversation Sarah should mention to me that I've been "living large". Now I'm not paraphrasing. It reminded me a bit of this xkcd comic 'Zealous Autoconfig'. Hopefully this is the extent of the manipulation and mind games that the Wii Fit will perform.

GPS Stolen

My GPS was stolen last night or this morning and I'm missing it already. For instance when I drove to Novus glass repair to get my front passenger window replaced I drove down the wrong road for a while.

When I got out of my apartment this morning there was a police car sitting in my parking lot and the officer asked me: "David? ... What'd you leave in your car?". My face must have changed a lot when I had the following sequence of realizations: (a) a police officer is asking for me by name, (b) I'm not in trouble, (c) my car must have been burgled, and (d) my GPS must be stolen.

The officer was waiting outside my complex because someone had reported my car's broken window to the police in the morning. The officer was very courteous and upon taking my date of birth noted that we were born on exactly the same day. The window's safety glass was shattered and lying in tons of tiny pieces all over the passenger seat, my glove box was open and the middle armrest where I keep my CDs was open. Nothing appears to be missing other than the GPS, the GPS power cable, and the GPS dash mount. Adding insult to theft, the their scattered my CDs throughout my car and didn't take any of them, insulting my taste in music.

My car's window should be repaired now and hopefully the rain that came in through the broken window until I covered it with plastic bags (classy!) didn't do any permanent damage.

Generating N-D Tetris Pieces

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

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

Kids in the Hall Live in Seattle

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.

Finished Paper Mario Games

Sarah and I have finished playing through the games "Paper Mario", "Paper Mario: The Thousand-Year Door", and "Super Paper Mario" last week (including the various Pits of 100 Trials). We played them all on the Wii, because even though Super Paper Mario was the only one released explicitly for that platform, Wii maintains compatibility with Game Cube games such as Thousand-Year Door and Paper Mario although originally released for the Nintendo 64 is now available as a pay for download game on the Wii's Virtual Console. So, yay for Nintendo!

I think my favorite of the three is Thousand-Year Door mostly because of the RPG attack system. In Thousand-Year Door and Paper Mario when you come into contact with an enemy you go into an RPG style attack system where you take turns selecting actions. In Super Paper Mario you still have hit points and such, but you don't go into a turn based RPG style attack system, rather you do the regular Mario jumping on bad guys thing (or hitting them with a mallet etc...). Thousand-Year Door and Paper Mario are very similar in terms of game play but Thousand-Year Door looks very pretty and has made improvements to how your party-mates are handled in battle (they have HP and can fall as you would expect) and there's an audience that cheers you on during your battles.

Even if the gameplay sucked the humor throughout the series might be tempting enough. Mario's clothing and mustache are mocked throughout and standard RPG expectations are subverted. I hate to describe any of these moments for fear of ruining anything but, for instance, an optional and very difficult enemy who may only be killed after hours of work only results in one experience point, or a very intimidating enemy who you imagine you'll have to fight actually challenges you to a quiz.

Despite how I personally rank them, all the games are great and I'd recommend any of them.

Cirque du Soleil in Marymoor Park

Sarah and I went to Cirque du Soleil's Corteo this past Wednesday. Its in Marymoor Park quite near the main Microsoft campus. They setup large circus tents in the park including a gift shop, overpriced concession stands, and long lined porta-potties. Despite all this the show was very entertaining and quite enjoyable. The show is like a circus directed by Terry Gilliam or Tim Schafer and otherwise I'm not sure how to describe it, but I do recommend it.
