I spent some time this afternoon poking around the Dallas Semiconductor web site, and ordered a One-Wire Weather Station Kit. Keichii is excited about helping, so I'm going to plunge into the early design work for a project I've wanted for a long time, my OpenSail project.

The initial goals for OpenSail are quite modest: given a wind direction and velocity from the One-Wire weather kit, and boat speed and direction from a GPS via serial/NMEA output, calculate and display the apparent and true wind speed. Later, we can add features like wind tracking, performance vs. polar plots, layline tack alerts, lifts, etc.

I spent some time poking into libvgl for graphics output, but that would limit it's portability. Since I'll probably run it on my VAIO, I think I'll stick with X for output. A friend at work suggested writing it in GTK-, since that will be good experience. I'll look into it more this week while I'm off work.

I wish I could afford to just do this full time.

Hacked up the tab-expansion code in Xchat. It was doing a rather lazy first-fit, and I kept talking to Greg Lehey's backup connection, groggy-B, instead of his primary connection, groggy-P. Attempts to modify his naming convention met with a stone wall of 'this is how we named things at Tandem, so it must be right.'

I also implemented a weighted selection; when you choose one amibguous definition over another it will prefer the one you just selected over all others. For instance, once you've addressed groggy-P in a message, the next time gr<tab> will select groggy-P over groggy-B and green.

I haven't decided if I like the weighting or not. I'll work with a few more days, make a decision, and contact the Xchat maintainer to see if he is interested in the patches. If not, I may add them to the BSD port/pkg kits.

Reading through the diaries of some of the other FreeBSD people here, I'm amazed at the number of people I've come to know over the years through the internet, but not in person. I'm still awed at the contributions these people make on a daily basis, and more than a little surprised at just how long I've known some of them. It's good to see more BSD people flooding in here, this looks like an interesting resource.

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.
