"I may be slow, but I'm sure."

Back when I was a wee lad, my mother bought me a children's record. One side had a narration of "The Little Red Hen", and the other "The Tortoise and the Hare". One of my favourite lines, spoken by the Tortoise on the B side of that record, follows me even now: "I may be slow, but I'm sure." And so it goes with my ongoing upgrade from Slackware 14.0 to Slackware 14.2.

Fiddling with GPS data

Last year, I collected some data from my car-mounted GPS, in order to update openstreetmap.org with a side-road into the lake at my cottage. As my GPS is only accurate to about 3 metres, and (on the drive along this side-road) often less accurate than that, I collected trackpoints from several drives up and down the side-road. This permitted me to refine the openstreetmap roadway path with a bit of accuracy, and add that side-road to the public map. This year, I hope to make many more trips to the cottage than I did last year.

A quick and dirty graphics converter for DigisparkOLED

A few months ago, I dragged my Linux laptop, some Digispark ATTiny85s, and some other hardware along to while away the time on an out-of-town visit. My objective was to, in my spare time, learn how to use some of the libraries available to the ATTiny85/Arduino environment, and to play a bit with the hardware.

A Slice of Pi

So, I'm reading a Usenet newsgroup and see this post talking about how to view the Raspberry Pi desktop on another machine. The post recommended downloading and installing yet another application to the Pi, and to the system that would view the Pi desktop. I guess that's the answer for some, but it's not the answer for me.

Into the Wild

Recently, I participated in a discussion about using Asterisk on the Raspberry Pi, to provide a call filtering facility for a home installation. My correspondant had tried to set up a Raspberry Pi and VoIP handset to handle phone calls such that incoming calls would pass through a whitelist/blacklist, promoting good callers and damning bad callers, while directing outgoing calls to their intended destinations.

Coping with change

A decade ago, I hosted a website for my partner, so that she could post photos and such for her family to see. She didn't use it much, and, in 2017, the hosting software reached end-of-life. So, I shut the site down, planning to upgrade the software and resurrect the site later.

Well, life got in the way, and I never did resurrect the site. Until now.
