On Monday in Germany we went to Marienplatz and wandered around
the Christmas Market, some of the stores, had drinks in a little pub, visited the Toy Museum, and checked out an impressive looking church. We accidentally drew in some other tourists as we stood
gaping at the Glockenspiel tower waiting for the little show to begin at the wrong hour. That night Megan and Oliver came by our hotel and took us out to a traditional Bavarian restaurant and
brewery that had been brewing beer there for hundreds of years. It was fun although we may have kept Megan and Oliver out too late on a weeknight.
The next day we went to the Deutsches Museum the largest science and technology museum in the world. And indeed it is very large, six floors
on a large grounds. I needed to better pace myself: I spent too much energy being interested in the engineering sections with steam engines, mining, aerospace etc. I was completely worn out by the
time we got to physics, chemistry, etc. etc. and we didn't even look in the natural sciences section. Anyway, its very large. That night we ate with Jon at an Italian restaurant. During the meal
two period dressed children came in and began singing then tried to shake down their captive audience in the restaurant asking for money. The man at the table next to us asked one of the children
what charity the money was going towards, the child said they kept the money, and the man said never mind then and sent the child away.
The text/plain fragment documented in RFC 5147 and described on Erik Wilde's blog struck my interest and, like the XML fragment, I wanted to see if I could implement this in IE. In this case there's no XSLT for me to edit so, like my plain/text word wrap bookmarklet I've implemented it as a bookmarklet. This is only a partial implementation as it doesn't implement the integrity checks.
Check out my text/plain fragment bookmarklet.
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've made an XSLT Meddler script in my continued XSLT adventures. Meddler is a simple and easy web server that runs whatever JScript.NET code you give it. I wrote a script that takes an indicated XSLT on the server, downloads an indicated XML from the Internet and returns the result of running that XML through the XSLT. This is useful when you want to work with something like the Zune software or IE7's feed platform which only reads feeds over the HTTP protocol. I'll give more interesting and specific examples of how this could be useful in the future.
Last Thursday I saw a bunch of college friends that I hadn't seen in a while, despite all of us working at Microsoft, and Saul and Ciera who were visiting. We had dinner at Typhoon! which I haven't been to in quite a while. Daniil and Val brought their cute child. I got to see Charlie and Matt who I'm not sure I've seen since my 25th birthday. There was much nerdiness. I need to remember to organize such a night myself sometime in near future so I don't have to wait another year to see them.
On the weekend Sarah and I went out to dinner at Carnegie's, a former
public library in Ballard, Seattle that's now a restaurant. I saw the restaurant's website in Matt's delicious links and thought it looked interesting. The exterior and entryway look like a public
library, but just inside its redone as a sort of modern version of french classical with a bar and two dining rooms. No pictures since my replacement camera only arrived today, but there are
photos available. They serve french cuisine which was good and
not as expensive as I would have expected. An interesting place, although its a bit of a drive and I'm not sure if we'll be going back soon.
Netflix has recommended three party movies over my time with Netflix and if you're OK with movies featuring sex, drugs, rock&roll (or techno) as almost the main character then I can recommend at least The Boys and Girls Guide to Getting Down.
24 Hour Party People is based on the true story of Tony Wilson, journalist, band manager, and club owner (not all at once) around the rise of punk and new wave in England. Like many true-story based movies it starts off strong and very interesting but gets very slow at the end like the writers got bored and just started copying the actual events. Unless you have some interest in the history of music in the 80s in Manchester I don't recommend this movie.
Human Traffic is fun and funny following a group of friends going out for a night of clubbing and partying. I had to get over seeing John Simm as not The Master from Doctor Who but rather as a partying youth. It felt like it was geared towards viewers who were on something like the totally odd techno musical interludes with the characters dancing for no apparent reason. Otherwise the movie was good.
The Boys and Girls Guide to Getting Down is done in the style of an old educational movie on the topic of clubbing and partying. It sounds like a premise that would get old but they do a good job. While demonstrating drinking and driving they have scientists push a mouse around in a toy convertible. Enough said. It was funny and I recommend it.
