Notes:

I've been writing software for more than 20 years and have worked in most programming languages at one time or another including C, C++, Perl, Pascal, Modula-2, REXX, Python, PHP, JavaScript, even stuff like COBOL and Forth. I wrote and released a few long-forgotten shareware programs back in the early 80's before I discovered the concept of Free Software. At the time I was using OS/2, so I did the first OS/2 ports of libpng and zlib (well before either had reached version 1.0). These days I run Linux on just about everything. I've created or contributed patches to a number of free software projects. For years, I maintained a fork of mod_virgule for one of my websites, robots.net. In 2006, I took over Advogato and moved it to the same codebase.

I write web-related server-based software in my day job at NCC, a Dallas based company that does website design and software development.

In my spare time, I write software for embedded applications - robots! I'm a member of the Dallas Personal Robotics Group (their robotics mailing list is a great source of info on the subject). I get to play with all sorts of embedded computers ranging from 8 bit Motorola and Intel chips to full-blown PCs. I've got several perpetually unfinished robotics projects at any given time. On most Tuesday evenings, you'll find me at the DPRG Lab working on robots or debating philosophy with other robot builders. If the weather is nice, I can sometimes be found wandering around the First Saturday Sale here in Dallas, TX. Oh, and I also maintain the Robot Competition FAQ which you may have seen floating around comp.robotics.misc.

I came of age in the 80's and it left me with an appreciation for classic arcade video games. As a member of VAPS, I restore vintage arcade games from time to time. I'm also an ODP/DMOZ editor, though ODP has become something of an anachronism in the modern world of social bookmarking.

What? You're not bored yet? Okay, let's see. I read a lot of science fiction, particularly the classic stuff from the 1930s-1950s. I also read modern SF authors like Neal Stephenson and Rudy Rucker (two of my favorites). I listen to a wide range of musical styles. You're just as likely to find me at a performance of the Dallas Symphony as at live show by a hardcore punk band. I'm interested in geodesic domes, space travel, the history of utopian communities, green city planning, and many other weird and wonderful topics.

Merry Christmas

Another Christmas has come and gone. On Christmas Eve Susan cooked a pot roast in the traditional style I grew up with. The meat came from a small order we placed with Dominion Farms, a local organic farming operation. All their animals are fed natural diets, no hormones or antibiotics. The meat was really tasty, so we'll probably get more from them in the future. My brother Randy joined us for dinner and we played several games of Scrabble afterwards while eating Apple Pie.

Susan and I spent Christmas morning at home opening a few presents for each other and then we drove up to McKinney to spend the rest of the day with family and friends. There was more opening of presents, large quantities of food, and lots of catching up on family news. We played a couple of games include Mexican Train dominoes and something new called Catch Phrase that our niece and nephew talked us into.

I spent some time helping my nephew rip audio tracks from a CD to use as ringtones on a his new phone. I'd forgotten how difficult it can be on Windows boxes to do simple things like converting from one audio file format to another. His phone needed MMA or MP3 audio but Windows would only rip CDs in WMA format. I Googled for downloadable sound utilities but could only find crappy shareware and freeware stuff that mostly didn't work. Then it occurred to me to see if any free software audio tools had been ported to Windows. I was pleasantly surprised to find Audacity for Windows. It's really amazing how much better most free software apps are compared to your average Windows programs these days! Audacity really saved the day for us. We were able to edit the track down to size, convert it to MP3 and get it onto his phone's SD card. And all in time to grab a piece of home made fudge before it vanished.

Thanksgiving weekend

On Thursday we had a traditional Thanksgiving dinner at our house. In addition to Susan and myself, my brother Randy and a friend of his attended. After eating turkey and dressing, we played a dominoes game called Mexican Train that's perfect for holidays since it can takes hours to complete. In the evening Susan and I drove to my sister Vicki's house where we visited other relatives including my parents and my sister Kelly's family.

Susan and I spent the rest of the weekend on our own. We've been playing more games in our spare time lately. We've read a lot of articles lately suggesting they're helpful in keeping our brains going. It also seems to be a good way to de-stress after work. Let's see, we're playing Scrabble, Mancala, and a variety of card games. One game I'd really like to start playing is Go.

We ventured out to a few Black Friday sales but tried to avoid any places that looked too busy. We picked up a pre-lit Christmas tree for the office that we set up and decorated Saturday night.

I also squeezed in some time to work on mod_virgule for the first time in nearly a year. I picked up where I left off in early 2008 with the rewrite of the HTML parser. I now have the libxml2-based parser working quite well. It needs a little more work to purge some remaining XSS holes. It already looks a lot safer than mod_virgule's built-in parser.

It seems like everyone I know is writing novels this month as part of the National Novel Writing Month event. The idea is that you write a 50,000 word first draft during November. You have to start from scratch on or after the first and you have to upload the finished work by Nov 30. Last year they had over 100,000 participants and more than 15,000 finished their novel on time. According to their FAQ, quite a few of these novels make it through further drafts, get published, and at least one made the number one spot on the NY Times best seller list.

REMEMBER TO VOTE TODAY!

If you're in the US, this is the last day to vote. I voted last week during the early voting period. We've got two good choices this year and either one is so much better than what we've had for the last eight years, that there will be cause to celebrate tomorrow. This is the end of an administration that has overseen the curtailment or destruction of many of our civil rights, they started an unnecessary war that's killed hundreds of thousands of people, they're imprisoning and torturing people without due process, they've pushed the economies of the US and much of the rest of the world into a major recession. It will probably take decades for the US and the world to repair the damage done by the Bush administration but the first step toward recovery is today's vote. So be happy. If you're in the Dallas, TX area and want to celebrate, I'd suggest the NO-MO-BUSH! Post-Election Party and Hoedown at the AllGood Cafe in Deep Ellum from 8pm to 11pm on Wednesday, Nov 5.

The Austin Maker Faire was last weekend and I was there, of course. I got a different view of it than last year because I spent part of the time as a maker. I helped out at the Dallas Personal Robotics Group table, where we showed off a variety of a small robots. We had several autonomous mobile robots, a robot arm that Martin interfaced with a game controller, a variety of robot components, and a couple of robot-like art pieces that were the result of my recent obsession with welding.

We did pretty well. There was a good-sized crowd of people at our booth throughout the faire, handling our robots and playing with the robot arm. Our table won an editor's choice award from Make magazine. And we're already talking about how we can do something bigger and more interactive next year.

All the usual crazy stuff was there too; cyclecide with their human powered carnival rides, including one they didn't have last year called the Melody Maker, in which the rider propels spinning guitars to make music. The Austin Bike Zoo brought a 50 foot human powered rattlesnake that could be seen slithering in and out of the show barn and surrounding areas during the faire.

The Austin Robot Group had the giant ponginator robot, which is probably the biggest, loudest robot to be found in the State of Texas. They had about a dozen tables of smaller projects too. There were also fire-spewing machines, strange vehicles, medieval siege weapons, the Swap-O-Rama, DIY metal forging, liquid nitrogen ice cream, wind generators, linux clusters, pretty girls, (with mohawks), pirates, (and a pirate ship), tesla coil music, and a nice sunset on Saturday night.
