Into the Monastery

Every once in a while I will look back at this blog of a year ago to see what I was doing then. I was wondering what the weather was like. It turns out it was milder, no surprise. I was working on the exterior of the boat and building the outrigger canoe.

Bon Voyage Crawdad

The cold snap, which is the coldest weather I have experienced down here in St Marys seemed to persist longer than forecast, about a week. It has been freezing overnight and most of the mornings, temperature going down to 28 on successive nights. This is nothing compared to what people up North are [...]

The Penguins Have Us

The coooold snap that is freezing us to death is only affecting the Keys a bit, maybe ten degrees less, so 50‘s and 60‘s instead of 60‘s and 70‘s, or 70‘s and 80‘s. The Keys and Bahamas are where to be in the dead of winter.

Happy New Year Chart Wrap Up

It is Sunday, New Year's Eve Day, and I have come down with a cold. My chart work is finished. I can't imagine going outside to work on the hull bottoms now. I may run out of paper towels to sop up my runny nose.

When THE COMPUTER GUY was talking to me about running shell scripts to convert old charts I had mentioned I liked to manually crop each chart and save it from the image manipulation program. Every chart. He looked at me funny. The shell scripts are ways to do a lot of that manual data processing and [...]

Sir, Render

The procedure to convert old electronic charts in the tiled .pcx format to charts that newer nav programs can use involves bulk processing with shell scripts. The shell scripts I needed to use are located in a compressed archive called pcx2tif.

Panasonic CF-C1 Toughbook

13 May 2017 | st marys, ga
Capn Andy/Warm Spring
Here’s a shot of the little Panasonic Toughbook CF-C1. These can be had, used, online for less than a hundred bucks. If you are lucky, you can get one that still has its hard drive. This one cost me about $80 and came with a 320 GiB drive. The wifi wasn’t operative, but I have an external powered antenna that worked fine with this computer. It had Windows on it, password protected, but I planned on loading it up with the latest Navigatrix operating system, which is based on the Ubuntu linux operating system.
The navigatrix site has a support section that can help with the installation. This computer doesn’t have a DVD/CD drive, so burning an installation disk wouldn’t work. Instead a USB stick was used and “USB HDD” was selected in BIOS as the boot device. Installation takes a little while. One peculiarity was that when I entered my password during the install, I must have hit the caps lock button, because when I later tried to start it up and login, I had to turn on caps lock. There is another peculiar thing with the num lock button. When the computer boots up, it turns on num lock just before the login page comes up. You have to turn it off. So I have two buttons to address during login.
The CF-C1 that I have has an Intel Core i5 processor and came with 4 GiB of RAM. It seems to run a lot faster than the older Core Duo machine it will be replacing.
The old CF-52 is clunkier and actually not as rugged as this little Toughbook. It has liquid resistant keyboard and is said to withstand a 30 inch drop (like from the table to the floor) without interrupting the operating system. It’s not as rugged as the Getac B300X, but it weighs less than 3 pounds and the Getac is around 8.
It has a touch sensitive screen and can be converted to a tablet by rotating the screen and closing it with the screen showing. There is a built in stylus and I found it useful when in the normal laptop mode to quickly select things instead of moving the cursor around with the touchpad.
It has a brighter than ordinary screen for daylight viewing, but it is nowhere near as bright as the Getac, which is truly daylight viewable. When it comes time to take the laptop to a marina lounge, this CF-C1 will be the one to carry, not the Getac.
