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:
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.

This past
Saturday Sarah and I took the Savor Seattle Tour of various food shops in Pikes Place. Sarah had suggested it at one point and when Jesse and Nicole
brought it up again when they came up to Seattle we decided to go. Surprisingly our tour group consisted of mostly locals. Except for the fish market I hadn't been to see any of the places on the
tour. I particularly enjoyed the chocolate cherries and the tea. Our tour guide Tim was funny and overall I enjoyed the tour and would recommend it. I've made a map of our tour including what free trials we got at each location. Yum!
This post is about creating a server side z-code
interpreter that represents game progress in the URI. Try it with the game Lost
Pig.
I enjoy working on URIs and have the mug to prove it. Along those lines I've combined thoughts on URIs with interactive fiction. I have a limited amount of experience with Inform which generates Z-Code so I'll focus on pieces written in that. Of course we can already have URIs identifying the Z-Code files themselves, but I want URIs to identify my place in a piece of interactive fiction. The proper way to do this would be to give Z-Code its own mimetype and associate with that mimetype the format of a fragment that would contain the save state of user's interactive fiction session. A user would install a browser plugin that would generate URIs containing the appropriate fragment while you play the IF piece and be able to load URIs identifying Z-Code files and load the save state that appears in the fragment.
But all of that would be a lot of work, so I made a server side version that approximates this. On the Web Frotz Interpreter page, enter the URI of a Z-Code file to start a game. Enter your commands into the input text box at the bottom and you get a new URI after every command. For example, here's the beginning of Zork. I'm running a slightly modified version of the Unix version of Frotz. Baf's Guide to the IF Archive has lists of IF games to try out.
There are two issues with this thought, the first being the security issues with running arbitrary z-code and the second is the practical URI length limit of about 2K in IE. From the Z-Code standard and the Frotz source it looks like 'save' and 'restore' are the only commands that could do anything interesting outside of the Z-Code virtual machine. As for the length-limit on URIs I'm not sure that much can be done about that. I'm using a base64 encoded copy of the compressed input stream in the URI now. Switching to the actual save state might be smaller after enough user input.
I got a FlickrMail from Emma J. Williams a bit ago saying that they wanted to
use two of my photos in their Schmap San Francisco Guide online travel guide. So now you can see two of my vacation photos on the Westfield San Francisco Shopping Center Schmap page and the Hotel Diva Schmap page.
I think its wonderful that digital cameras are at
the point where I really don't have to know much about their workings to produce a photo that's reasonable looking. And its thanks to Flickr and searchable tags that Schmap could find my photos.
Since my photos on Flickr are all licensed under a Creative Commons license named Attribution-Noncommercial-No Derivative Works
2.0 Generic which only applies to non-commercial uses, Schmap, which is advertisement supported, kindly asked me if they could use my photos. I agreed to their license which was human readable
and included wonderful stuff like I get in place attribution and the license is only applicable while Schmap makes their guide freely available online.
Previously I've only heard of folks having their flickr photos used without their permission so I'm glad to know that's not always the case. Or perhaps this is just Schmap's clever method of getting me to blog about them.
In Toronto we visited the CN Tower, the ROM, and the Bata Shoe Museum. We generally acted like tourists walking around taking photos of things, putting on sun block, and not saying 'eh'. But we could have been worse
like the drunk American college students in front of us in line for the CN Tower asking the guide if the CN Tower is taller than the Stratosphere in Las Vegas. We stumbled upon the Toronto Outdoor Art Exhibit which was really interesting. Sarah in particular recalls the cute stuffed animal
monsters.
After Toronto we drove to Burlington where Palak and Meghal's wedding would take place. We got up early and made it on time to the wedding which was
lovely. I hadn't attended an Indian wedding previously so it was a new experience for me. During the ceremony the child in front of me kept peeking over her parent's shoulder and staring at me. It
lasted all day with a break after lunch during which we drove around and experienced small town Ontario. After the break cousins performed dances for Palak and Meghal and then we all danced the night
away until the wee hours.
In Niagra we stayed in a hotel room with a falls view which was lovely. We went on the Maid of the Mist tour that takes tourists
right up to the falls in a boat and drenches them. We also went on the Behind the Falls tour which was not as fun. In both we are
given rain coats which are essentially glorified plstic trash bags. For dinner we ate in the hotel restaurant which had a lovely view of the falls. At night the falls are lit up in various colors
with gigantic lights.
