My parents visited this past weekend, met Sarah's parents, saw our house, and met our bunny. On Friday we went to BluWater in Kirkland which was pretty busy and the service was slower and slightly worse than we usually find. Saturday my parents helped us with our yard quite a bit and for dinner we went to the Icon Grill with Sarah's parents. I had forgotten how much I enjoy the food at the Icon Grill - I had the very tasty meat loaf. Dinner went well and afterward we stopped at the Three Lions pub in Redmond. On all previous occasions I had tried to go in there the place was packed for a soccer game. This night however there was a man with a guitar, singing and it wasn't nearly as packed. I also found that near the bathrooms on the wall is what looks to be James Bond's jetpack.
On Sunday we went out to see Jeannie and Carl and see the renovations to Jeannie's place. We met up with them at the Fremont Market to which I hadn't been previously, and had a look around there before going back to Jeannie's to see the lovely work they'd done to her place. For dinner my parents took us out to the Melting Pot for my approaching birthday. It was fun having my parents up and I look forward to the next time they're here.
I've looked at my web server logs previously to see if anyone had used my Web Frotz Interpreter and until recently didn't realize that awstats (the web server log report generator) was truncating the query from my URL, so I couldn't tell that anyone was actually using it. But after grepping the logs manually I've pulled out the URLs of visitor's text adventure sessions. If you'll recall, my Web Frotz Interpreter stores the game state in the URL so its easy to see user's game states in the web server logs.
I've put some of the links up on the Web Frotz Interpreter page. Some of the interesting ones:
There can be no doubt that infomercial pitchmen Billy Mays and Vince Offer are awesome, but how can I decide which is my favorite?
Sarah and I are back from Munich, Germany as of Thursday and I've just about recovered. The trip there via Air France we watched many movies and
it was much better than the trip back in which the entertainment system failed and I had a cold. When we arrived, Jon met us at the airport, helped us with the subway system, we played Guitar Hero,
ate at a Bavarian pub, and then later at an Australian bar.
The following day we met up with Jon and three of his friends, one of
whom was visiting from England and we all took a train to Neuschwanstein Castle. Apparently its the 'Disney' castle in that Disney's castle's are based upon it. The castle is filled with images and
statues of swans in homage to the Swan Knight. We ate in the town at a cafe with traditional Bavarian food before taking the train back and getting all you can eat fajitas for dinner.
PowerShell gives us a real CLI for Windows based around .Net stuff. I don't like the creation of a new shell language but I suppose it makes sense given that they want something C# like but not C# exactly since that's much to verbose and strict for a CLI. One of the functions you can override is the TabExpansion function which is used when you tab complete commands. I really like this and so I've added on to the standard implementation to support replacing a variable name with its value, tab completion of available commands, previous command history, and drive names (there not restricted to just one letter in PS).
Learning the new language was a bit of a chore but MSDN helped. A couple of things to note, a statement that has a return value that you don't do anything with is implicitly the return value for the current function. That's why there's no explicit return's in my TabExpansion function. Also, if you're TabExpansion function fails or returns nothing then the builtin TabExpansion function runs which does just filenames. This is why you can see that the standard TabExpansion function doesn't handle normal filenames: it does extra stuff (like method and property completion on variables that represent .Net objects) but if there's no fancy extra stuff to be done it lets the builtin one take a crack.
Here's my TabExpansion function. Probably has bugs, so watch out!

I finally replaced my old regular cell-phone which was literally being held together by a rubber band with a fancy new G1, my first Internet accessible phone.
I had to call the T-Mobile support line to get data added to my plan and the person helping me was disconcertingly friendly. She asked about my weekend plans and so I felt compelled to ask her the same. Her plans involved replacing her video card so she could get back to World of Warcraft and do I enjoy computer gaming? I couldn't tell if she was genuine or if she was signing me up for magazines.
I was with Sarah in her new car, trying out the phone's GPS functionality via Google Maps while she drove. I switched to Street View and happened to find my car. It was a weird feeling, kind of like those Google conspiracy videos.
The phone runs Google's open source OS and I really enjoy the application API. Its all in Java and URIs and mime-types are sort of basics. Rather than invoking the builtin item picker control directly you invoke an 'intent' specifying the URI of your list of items, a mime-type describing the type of items in the list, and an action 'PICK' and whatever is registered as the picker on the system pops up and lets the user pick from that list. The same goes if you want to 'EDIT' an image, or 'VIEW' an mp3.
I wanted to replace the Google search box gadget that appears on the home screen with my own search box widget that uses OpenSearch descriptors but apparently in the current API you can't make home screen gadgets without changing parts of the OS. My other desired application is something to replace this GPS photo tracker device by recording my location to a file and an additional program on my computer to apply those locations to photos.
The weekend before last Sarah and I went down to Gas Works Park in Seattle. Gas Works Park is a former Seattle Gas Light Company gasification plant now turned into a
park with the machinery kept intact and found right on the shore of Lake Union. There's a large hill right next to the plant with an embedded art installation from which you get an excellent view
of the park and the lake. Anyway a very cool place. Afer, we ate at Julia's of Wallingford where I stereotypically had the Santa Cruz
omelet. Good food, nice place, nice neighborhood.
This past weekend was Halloween weekend. On Halloween at Microsoft parents bring their kids around the office buildings and collect candy from those who
have candy in their office. See Matt's photo of one such hallway at Microsoft. The next day Sarah and I went to two birthday parties the second of which required costume. I went as House (from the
television show House) by putting on a suit jacket and carrying a cane. Sarah wore scrubs to lend cred. to my lazy costume. Oh yeah and on Sunday Sarah bought a new car.
