BBQ x 2

2007 Jun 11, 3:36This past weekend I was invited to two BBQs. Consequently, the weather took a break from the heat to drizzle.

The first was a lunch BBQ in celebration of Sarah's mom getting her Masters degree. Sarah and I went to her sister's house on the East-side where we had traditional foods you might associate with a BBQ including some enjoyable sausage. There was a bit of Wii to be had and Sarah's mom killed at bowling. Sarah seemed a bit dismayed at this. I guess Sarah didn't expect it since she's had more experience compared to her mom who was playing for the first time.

For dinner we drove over to Seattle to have a BBQ at Jeannie's house. Jeannie's family and my family became friends through our church when I was born and Jeannie even babysat me. The second bit about the babysitting is how Jeannie would introduce me at the BBQ. I met her boyfriend who seems like a cool guy. He works for Microsoft as a consultant and has traveled to various countries for his job. Guests had been instructed to bring side dishes and so there was quite a spread which was eclectic as well. We brought red potatoes, humus, and pita bread. As it turns out, one of the other guests had produced humus in bulk as a supplier and apparently had a grudge against the big humus chains. We played it cool and she didn't say anything so we can only assume she didn't know it was us. Jeannie was a great hostess and I had a fun time.bbq washington personal nontechnical

Wiimote wiissues

2007 Jun 7, 5:29The other day I had the best idea for my Wii remote. Clearly I should use it to control the rotation of Tetris pieces in my N-dimensional Tetris game Polytope Tetris. One of the issues I described with Polytope Tetris is user input. Given a Wii remote the user could rotate a piece through 3 dimensions in a manner that's much easier to adjust to than particular keys on the keyboard.

Anyway, I did a little research into how this might work. I knew that the Wii remote used infrared for absolute positioning and Bluetooth for everything else (LEDs, speaker, accels.) I bought a Bluetooth adapter for my PC after realizing that none of my computers had one already. I used GlovePIE to ensure that my Wii remote could connect and successfully communicate with my computer. GlovePIE is actually pretty cool -- it provides a simple script layer over the Wii remote to control things like your mouse.

Since Polytope Tetris is in Java I looked for and found a Java library for operating with the Wii remote and a long forum thread discussing its use. I then read up on Bluetooth in Java. Apparently JSR 82 is the name of the standard that describes the API a Bluetooth stack should expose in Java. That is, to get Bluetooth working in Java one needs an additional package for Java that actually implements the Bluetooth Java API. This package would depend on the system so I suppose I can't fault Sun for not including it... Where to find such a package? I found a comparison list of implementations and tried the ones that support javax.bluetooth. None of them worked for me because none can address USB devices it seems or they cost money and I couldn't get the trial version working. I also tried bluesock (not listed on the previous list) which seemed promising and could produce an address for my Wii remote as a connected device but couldn't use that address.

And I thought that after I found the Wii remote Java library it would be easy... Oh well...java bluetooth wii technical remote jsr82 tetris polytopetetris wiimote

XPointer Framework - IE7 XML Source View Upgrade Part 3

2007 May 17, 5:16Previously I created some resource tools and then I used them to overwrite msxml3's XML source view. In this update I've added support for the XPointer Framework.

This time around I've started to add support for the XPointer Framework to my XML source view and I've added installation instructions. The framework consists of a series of pointer segments each of which has a scheme name followed by data in parenthesis. For example 'scheme1(data1)scheme2(data2)scheme3(data3)'. A pointer segment resolves to a portion of the XML document based on the data and the scheme name. The whole pointer resolves to the first segment that successfully resolves. That is, from the example, if scheme1 resolves to nothing and scheme2 resolves to something then that's used and scheme3 is ignored. In addition to the framework I've added support for the xmlns scheme which binds namespace prefixes to a namespace URI and the element scheme which is a simple way to resolve to particular elements in an XML. I also have limited support for the xpointer scheme the content of which is resolved as an XPath with some extra functions (which I don't support -- hence the limited). I've also thrown in schemes for the two SelectionLanguage values supported by msxml3.

Next time I might try to support the xpointer functions that aren't in xpath using msxml script. But I think I'm losing steam on this project... we'll see.resource technical xml xpointer res xpath xslt

MoHo Living

2007 May 13, 12:16My parents and grandmother came to visit the weekend before this current weekend, starting Friday May 4th. They arrived via their new motor-home which is quite the machine. Of course its my parents motor-home so its very well decorated inside including drapes and mini-chandelier. I didn't have a memory card for my camera at the time but I'm sure my parents will put up photos on their new blog dedicated to their motor-home at some point in the future.

At any rate, they parked the motor-home in an RV park in Issaquah so that Friday night I drove over to them and we ate at the conveniently closely located Pogachas. The next day they came over and I showed them the various cool looking things my computer connected to my flat screen TV can do. This includes Vista Media Center showing my photos from recent trips and Google Earth mapping out our respective homes and my recent trips (and Paris). Additionally, we played Wii which, unsurprisingly based on anecdotal evidence from varied sources across the Internet, was a seeming hit. Mom broke records playing bowling with my dad and I, Dad did an excellent job fishing, and Grandma's slow but steady win's the race approach to cow racing worked very well.

The next day I drove them to Seattle and we walked around Pike's Place. My parents made dinner that night at my place which was very good and made my apartment actually smell like cooked food. Also, we exchanged Christmas gifts. For the past two years I've flown back to my parents' house for Christmas and ended up with gifts I couldn't take with me in both directions. Those I left at their house they drove up and I was able to give them the ones I left at my place. They started the drive back the next day. I really enjoyed seeing them here.motorhome family personal nontechnical

New XSLT - IE7 XML Source View Upgrade Part 2

2007 May 11, 8:55Last time, I had written some resource tools to allow me to view and modify Windows module resources in my ultimate and noble quest to implement the XML content-type fragment in IE7. Using the resource tools I found that MSXML3.DLL isn't signed and that I can replace the XSLT embedded resource with my own, which is great news and means I could continue in my endevour. In the following I discuss how I came up with this replacement for IE7's XML source view.

At first I thought I could just modify the existing XSLT but it turns out that it isn't exactly an XSLT, rather its an IE5 XSL. I tried using the XSL to XSLT converter linked to on MSDN, however the resulting document still requires manual modification. But I didn't want to muck about in their weird language and I figured I could write my own XSLT faster than I could figure out how theirs worked.

I began work on the new XSLT and found it relatively easy to produce. First I got indenting working with all the XML nodes represented appropriately and different CSS classes attached to them to make it easy to do syntax highlighting. Next I added in some javascript to allow for closing and opening of elements. At this point my XSLT had the same features as the original XSL.

Next was the XML mimetype fragment which uses XPointer, a framework around various different schemes for naming parts of an XML document. I focused on the XPointer scheme which is an extended version of XPath. So I named my first task as getting XPaths working. Thankfully javascript running in the HTML document produced by running my XSLT on an XML document has access to the original XML document object via the document.XMLDocument property. From this this I can execute XPaths, however there's no builtin way to map from the XML nodes selected by the XPath to the HTML elements that I produced to represent them. So I created a recursive javascript function and XSLT named-template that both produce the same unique strings based on an XML node's position in the document. For instance 'a3-e2-e' is the name produced for the 3rd attribute of the second element of the root element of the XML document. When producing the HTML for an XML node, I add an 'id' attribute to the HTML with the unique string of the XML node. Then in javascript when I execute an XPath I can discover the unique string of each node in the selected set and map each of them to their corresponding positions in the HTML.

With the hard part out of the way I changed the onload to get the fragment of the URI of the current document, interpret it as an XPath and highlight and navigate to the selected nodes. I also added an interactive floating bar from which you can enter your own XPaths and do the same. On a related note, I found that when accessing XML files via the file URI scheme the fragment is stripped off and not available to the javascript.

The next steps are of course to actually implement XPointer framework parsing as well as the limited number of schemes that the XPointer framework specifies.xml xpointer msxml res xpath xslt resource ie7 technical browser ie xsl

San Francisco Trip

2007 May 11, 7:48After Carissa and Elijah's wedding Sarah and I went to San Francisco. We drove in, well Sarah drove anyway, still in the PT Cruiser Sunday morning and checked into our hotel, Hotel Diva. I was originally concerned that I wouldn't fit in as I don't really consider myself a diva, however the hotel was cool. They have Internet rooms setup in various themes, the front desk is always staffed, our room had a very modern look, and when we entered the flat-screen over the front desk was playing an episode of Aqua Teen Hunger Force.

We walked around a bit before going to the SF Museum of Modern Art. There was a Picasso exhibit at the time which we could see for only $3 more. It felt kind of wrong like my ticket was super-sized. I think the most memorable piece I saw was three white panels which consisted of three blank panels. Art. Sure. After that Sarah wanted to see the giant Hello Kitty store she had heard of from her sister. We ended up going to the Westfield Shopping center which has a disappointingly average sized Hello Kitty store. Apparently the giant one is gone. That night we went to First Crush for dinner. I had a flight of wine which consists of three one-third sized glasses of various but complimentary wines. It was a great restaurant in terms of food, drink, atmosphere and service.

The next morning we were even more the tourists when we went down to Fisherman's Wharf and Pier 39. We visited the famous wax museum and purchased multiple pounds of taffy. On the way back to the Oakland airport we got to experience a little traffic as part of the 580 freeway had collapsed the morning we arrived and was still under repair on our way out. We survived of course and I think the trip went rather well.sanfrancisco personal california sfmoma nontechnical

Roommate Wedding

2007 May 5, 10:05Carissa and Elijah are married! Sarah and I flew to Oakland the Friday of two weeks previous (April 27th) into the Oakland Airport. We were on the same flight as Jon which was fun but we weren't seated with him. Instead I was seated between Sarah and a middle aged lady who enjoyed talking to herself. It seemed a bonus if others such as myself listened but not a prerequisite for her speaking.

Sarah and I rented a car and we drove Jon first to Hayward where he was staying then we drove to our hotel in Dublin. The car we got turned out to be a PT Cruiser which was a surprise of course but actually wasn't that bad. The power windows are controlled by the center console rather than by a switch near the windows themselves which led to several embarrassing seconds when we later tried to pay the toll for the Bay Bridge.

The next day we went to Carissa's wedding which was lovely. In a small church with white roses Carissa's mom married Carissa and Elijah. Afterward we went to the reception at the Senior Center. "Senior Center" may conjure up images of rolley charis that smell like old people but it wasn't like that at all. It appears to be a community center funded by the Senior Condos next door so it was very nice.

Carissa is the first of the college roommates to get married! I guess I'm just having trouble imagining any of us getting married...wedding friend personal california nontechnical

Missing Bee Roundup

2007 Apr 15, 4:06For the past several months I've seen various articles suggesting why bees are disappearing. At first I thought this was another crackpot's article that somehow made it onto digg.com. But they keep coming and sometimes from credible sources. After the article I saw tonight I thought I should go back and put together the various articles I've read on this topic. Bees may be disappearing due to pesticides, new organic pathogens, genetically modified crops, mobile phones, or climate change. Apparently, the US hasn't been keeping accurate counts of its bees so we don't know the extent of the situation. There's an interview with Maryann Frazier, M.S., of the Dept. of Etymology at Penn State and a congressional hearing on the matter.

I know this is all very serious and could signal the end of our ecosystem as we know it, but I can't help throwing in the following links as well. The bees could be hiding in this Florida couple's kitchen. Or perhaps they're laying low while being trained by the government to fight terrorism. Or they're hiding in extra dimensions that we mere humans can't perceive (I'm fairly certain that's what this article is suggesting. Really. Read it. Seriously. Its awesome.)roundup personal bees nontechnical

Bunny Weekend

2007 Apr 8, 3:46This weekend was fun. Sarah and I went out for Jane's Birthday. We ate at a little Italian restaurant where our group was almost too large for the place and afterwards went to the Viceroy lounge. The website apparently isn't very representative because although I looked at it before going out and I'd been to the place previously, I didn't realize it was the same location until we got there.

I got several games for my Wii through Sarah's connections including Wii Play and The Legend of Zelda: Twilight Princess. We played both of them and I thought Find Mii was especially fun.

Sarah's bunny is getting pretty big. Its been biting through wires now includig part way through the power cord to the cable box. You'd think after getting to the copper that it would learn to stop. At any rate, it didn't hide any eggs. I don't have any new photos but you can see the old bunny photos via my Vizicious tool.personal nontechnical seatle wii

Weekend Humor

2007 Mar 13, 8:16Over the weekend I went with Jon and Sarah to see Zach Galifianakis perform at The Moore who was awesome of course. I hadn't been to The Moore before but it was very cool. The space is very vertical with two levels of balconies making it seem small in the other dimensions. We were on the middle level so when Zach climbed off the stage to talk to the audience we couldn't see him.

Before the show we ate at The Steelhead Diner. I enjoyed my chicken sandwhich but the place seemed a little full of itself with salt and pepper that had been infused with this and that. At any rate it had a nice atmosphere and good food which I suppose is the point.

The opening act for Zach was another comedian whose name I don't recall. He was pretty funny but seemed to do just a tad too much pandering to the Seattle audience. "The administration should do something different than what they're doing currently!" *Audience Cheers* is sort of equivalent to "Its great to be here in... Seattle!" *Audience Cheers*.personal seattle nontechnical
