Another use for my new phone is as a replacement for my grocery card, those little plastic cards with a bar code on them that the grocery store gives you to track your purchasing habits. I've previously gone to great lengths to increase space in my pockets by removing infrequently used keys and reducing my wallet to the essentials. So I was glad to get rid of the QFC card and replace it with a photo of its bar code on my phone. Since the important part of the QFC card is the bar code which is just an image of black lines, if your phone has a camera and a screen with a reasonable resolution you can take a photo of the bar code and later display it to a reader. I've so far been able to try it once and successfully at a normal checkout line, but the reaction from the checkout lady was enough that I may in the future just keep a card in my car. She was very excited, asked me what kind of phone I had, called over another checkout person and generally made a large fuss. Also the checkout people generally don't mind giving me a new card if I don't have one with me.
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.
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.
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.
If you view a plain text document in Internet Explorer 8, for instance the plain text version of Cory Doctorow's book Little Brother and press F12 to bring up the developer toolbar, you can see that IE simply takes the plain text, sticks it inside a
tag, and renders it. This means that word wrapping isn't supplied and the only line breaks that appear are those in the document. However, since the text document is converted to HTML it means I can implement word wrap myself using a bookmarklet:javascript:function ww() { var preTag = document.getElementsByTagName('pre')[0]; preTag.style.fontFamily="arial"; preTag.style.wordWrap='break-word'; }; ww();
After adding a favorite and setting the favorite's URL to the previous, I can view plain text documents, and select my Word Wrap favorite to apply word wrap and non-fixed width font.
Windows allows for application protocols in which, through the registry, you specify a URL scheme and a command line to have that URL passed to your application. Its an easy way to hook a webbrowser up to your application. Anyone can read the doc above and then walk through the registry and pick out the application protocols but just from that info you can't tell what the application expects these URLs to look like. I did a bit of research on some of the application protocols I've seen which is listed below. Good places to look for information on URI schemes: Wikipedia URI scheme, and ESW Wiki UriSchemes.
Scheme | Name | Notes |

search-ms | Windows Search Protocol |
The search-ms application protocol is a convention for querying the Windows Search index. The protocol enables applications, like Microsoft Windows Explorer, to query the index with
parameter-value arguments, including property arguments, previously saved searches, Advanced Query Syntax, Natural Query Syntax, and language code identifiers (LCIDs) for both the Indexer and
the query itself. See the MSDN docs for search-ms for more info. Example: search-ms:query=food |

Electronic devices shouldn't fail, they should just sit wherever I place them and work forever. A while back my home web server started failing so I moved over to a real web hosting service. And this was the home web server I built from pieces Eric gave me after my previous one died during the big power failure the year before. The power socket on my old laptop has come undone from the motherboard so that it can no longer be powered. Just a week or two ago my Xbox 360 stopped displaying video. The CPU fan on my media center died. I also want to put my camera and GPS in this list, but the camera died due to accidentally turning on in my pocket and the GPS was stolen so those aren't the devices just arbitrarily failing.
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.
Sarah asked me if I knew of a syntax highlighter for the QuickBase formula language which she uses at work. I couldn't find one but thought it might be fun to make a QuickBase Formula syntax highlighter based on the QuickBase help's description of the formula syntax. Thankfully the language is relatively simple since my skills with ANTLR, the parser generator, are rusty now and I've only used it previously for personal projects (like Javaish, the ridiculous Java based shell idea I had).
With the help of some great ANTLR examples and an ANTLR cheat sheet I was able to come up with the grammar that parses the QuickBase Formula syntax and prints out the same formula marked up with HTML SPAN tags and various CSS classes. ANTLR produces the parser in Java which I wrapped up in an applet, put in a jar, and embedded in an HTML page. The script in that page runs user input through the applet's parser and sticks the output at the bottom of the page with appropriate CSS rules to highlight and print the formula in a pretty fashion.
What I learned:
The names in the following anecdote have been changed. Except for my name (I'm Dave).
I got a new laptop a while back. I had it in my office and Tim came in to ask me something but paused when he saw my laptop. "Oh, is this one of those new touch screen laptops?" he asked, the whole time moving his hand towards my laptop and punctuating his sentence by pressing his finger to the screen. "No" I responded.
Walking down a hallway I heard Winston, one of our managers, say, "Hey Tim!" Winston catches up to me and asks, "Are you almost done with the XYZ bug?" I realized Winston was talking to me and got my name wrong but I figured I'll ignore it and perhaps he'll realize his mistake. Winston continued "I just talked with some people who say they're blocked and waiting for Tim to finish the XYZ bug." "Dave" I said helpfully attempting to diplomatically correct Winston since he apparently hadn't realized his error. "No, it was Jeremy and Bill." Winston said naming the people he had talked to who were waiting for me to fix the XYZ bug. At this point I decided it would be easier to just answer his question and end the conversation than to get into this whole thing. As far as I know, Winston has not gotten my name wrong at any other time.
This past weekend Sarah and I went to Salty's on Alki. I had never been down to the Alki area so that was fun and I took a few photos while we were there. It turns out they were the last few photos I'll be taking with that camera as it turned itself on in my pocket and the lens extension mechanism broke for the inner most lens. So now I'm looking for a new camera, preferably one that has a lock mechanism so I can't accidentally turn it on in my pocket. The dinner was good and Salty's has a great view. On an unrelated note, the next day we went to an Audi dealership and test-drove the new 2009 A4 which was fun. I'm happy with my car but Sarah's feeling antsy.
Internet Explorer 8 Beta 2 is now available! Some of the new features from this release that I really enjoy are Tab Grouping, the new address-bar, and InPrivate Subscriptions.
Tab Grouping groups tabs that are opened from the same page. For example, on a Google search results page if you open the first two links the two new tabs will be grouped with the Google search results page. If you close one of the tabs in that group focus goes to another tab in that group. Its small, but I really enjoy this feature and without knowing exactly what I wanted while using IE7 and FF2 I knew I wanted something like this. Plus the colors for the tab groups are pretty!
The new address bar and search box makes life much easier by searching through my browsing history for whatever I'm typing in. Other things are searched besides history but since I ignore favorites and use Delicious I mostly care about history. At any rate its one of the things that makes it impossible for me to go machines running IE7.
InPrivate Subscriptions allows you to subscribe to a feed of URLs from which IE should not download content. This is intended for avoiding sites that track you across websites and could sell or share your personal information, but this feature could be used for anything where the goal is to avoid a set of URLs. For example, phishing, malware sites, ad blocking, etc. etc. I think there's some interesting uses for this feature that we have yet to see.
Anyway, we're another release closer to the final IE8 and I can relax a little more.
I've had a little fun messing around with Photosynth, a Microsoft research project turned into a Live service. You upload a bunch of photos from around the same area and it makes a 3D panorama out of them. For instance, here's National Geographic's photosynth of the sphinx and pyramids in Egypt. Messing around with this I've made one of half a vase of roses, and a larger photosynth of my office.
As noted previously, my page consists of the aggregation of my various feeds and in working on that code recently it was again brought to my attention that everyone has different ways of representing tag metadata in feeds. I made up a list of how my various feed sources represent tags and list that data here so that it might help others in the future.
