Cat Roundup

2007 May 17, 1:04I've seen several humorous kitty related stories recently and then happened upon the whole lolcat scene. Rather than post all the links to humorous kitty lolcat photos to delicious I figure I'll roundup the links here.

A cat in England enjoys riding the bus and does so regularly (associated lolcat commentary).

A cat trees a bear (also with lolcat commentary).

xkcd has a comic on the topic of lolcat commentary. xkcd also had a non-lolcat cat related comic recently that I found funny.

And now I'm out of commentary so I'll just... "X cat is X": interested, aggressive/defensive. VG related: SF, Zelda. Other: cookie, sad.roundup comic kitty personal cat humor nontechnical

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

Resource Tools - IE7 XML Source View Upgrade Part 1

2007 May 9, 4:15I read about text/xml URI fragment resolution a few months ago. I was interested to find another kind of fragment reference other than the text/html URI fragment but of course I didn't find an implementation in IE, Firefox, or Opera. I decided to see how much work would be required to implement this in IE.

In IE and Firefox when you open an XML file that doesn't have an XML stylesheet the XML source is rendered with syntax highlighting. In IE I also noticed that the gold bar appears when you open an XML file off of your local machine. To me this suggested that the XML source was being rendered as HTML which I assumed was produced by running an XSLT on the source XML file. If so, I figured I could modify the XSLT to implement text/xml URI fragments. I ran FileMon to see if iexplore.exe loaded an XSLT file when opening an XML file. Only the XML file and MSXML3.DLL were opened and no XSLTs were loaded as files. My next hope for modifying the XSLT was if it existed as a resource in MSXML3.DLL. I did a findstr on the DLL for SCRIPT and found an XSLT so I decided to check for resources in MSXML3.DLL. Unfortunately my previous resource viewer didn't work correctly so I decided to write my own.

I created resource tools to view and modify resources in Windows modules. The viewer outputs HTML with links to the individual resources of a module using the res URI scheme that's built into IE. The modifier is a simple command line tool that replaces or adds one resource at a time to a module.

Using these tools I found that the XSLT was stored as a resource in MSXML3.DLL. I'll talk more about the existing XSLT and the one I replaced it with next time.resource technical xml msxml res xslt xsl

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

Commenting Wishlist

2007 May 1, 4:33In the past I've come up with ideas for software and find that the very idea is implemented soon after. So this time rather than getting down about it I'm going to make it work for me. I'll state what I want to use and hope that its magically implemented. In order to uniformly support comments on my website I want a web service with the following features:

• Allow users to view and add comments for any particular URI.
• Use OpenID and optionally Card Space to identify users.
• Use a captcha system that's optionally cute or humorous.
• Has atom or rss feeds of the comments available.
• Doesn't require users to register.
• Doesn't require any extra steps for commenting on a URI that no one has commented on.

I'm going implement this now so no one go off and do it before me so that I can use it without having to do anything...technical homepage

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

Aqua Teen Hunger Force Colon Movie Film for Theaters

2007 Apr 15, 7:37Friday Jon, Daniil, and I saw Aqua Teen Hunger Force Colon Movie Film for Theaters. It was really great. The quality of individual Aqua Teen episodes varies wildly but this movie was very funny. It was like watching an excellent episode that happened to be 87 minutes long.

I had some difficulty generating interest for the movie as many didn't think this was 'their kind of movie'. I asked Sarah and she said no but I talked to her about it again later after she watched a clip and she said she really didn't want to see it because it looked too weird. I asked her what she saw in the clip and she said a man with weird pants was talking with french fries while a drink was getting a meatball to push him around in a cart.

Well, when you put it like that it does sound weird...movie personal nontechnical
