Always make a backup

I heeded some advice on Thursday last week. My little voice was telling me to make a backup of my Radio install. I stopped right then, shut Radio down, opened Stuffit Deluxe and archived the whole folder. I then copied the folder to different drive partition and restarted Radio. It was a good thing I did. (insert forboding music here)

I decided on Saturday (9-6) to open Matt Neuberg's book about Frontier and play a little. I thought I was being careful not to change anything, copying things to the workspace table before mucking about. Wrong. I did something somewhere and created an error rendering the weblog posts. This makes sense because I was reading the rendering code in Radio, trying to get an idea of how pages are rendered and when. This unfortunate mistake was just an annoyance. I killed the offending Radio, dumped it to the trash, opened the backup and unstuffed it. Restarted with the good Radio, and here we are.

Always make a backup…

My firewall was the problem

I have a wireless access point and firewall combo that protects my meager home network from the Internet. Yesterday, I disabled the wireless interface (since I wasn't using it) and all seemed well.

My caution was rewarded with inconvenience. Even though the firewall settings displayed no changes, port translation was affected. Since the disabling the wireless connection was the only difference, I heeded my little voice and turned it back on. I changed the port number for the source, saved the settings and retried. All was well. I changed it back on a hunch; still working.

Just to make sure, disabled the wireless interface, again changed the port numbers for the translation–no workie. I had the wrong firmware installed on my firewall–Rev B vs. Rev A. Downloaded new firmware, installed, reset, all fixed.

Update:  I'm reposting this from work to make sure all is fine remotely. –Now twice–

Tractor Sleds, GPS and Ideas

I was reading this on Tim's weblog and thought about a new type of tractor. Build a sled, much like a military tank, with an engine and GPS control equipment in the center on standard connections in the back. Put tandem connectors on the fronts to allow daisy-chaining like trains do. It would use treads like a tank, but designed for use in the mud. Use proximity sensors and software to help it make the turns; treads can turn tighter than standard wheels.

If it used standard components, it could be made cheaply enough to buy more than one for farms. The lower component cost would make up for the GPS add-ons. Also, replacement parts would be easy to install and maintain, plus switchable between units.
