Sarking

As I said at the end of my last but one house post, I'd engaged some local builders to put on the sarking boards and membrane.

Boats

Glanced up from my desk to notice a somewhat larger than normal boat somewhat closer inshore than normal. As it looked mildly photogenic I got my telescope out (Celestron 80mm NexStar refractor - it's f/5 so 400 mm focal length) to play with using the camera on the back a bit more.

Raspberry Pi Setup

I have an “always-on” Raspberry Pi 3 which does logging of temperature, pressure, power use and so on readings from around the house and county.

I've had it just over a year and it's been running the version of Raspbian (the Debian Linux distribution modified for the Pi) that was current when I got it. The logging has been to flat files containing lines of JSON but recently I started switching to a Sqlite3 database but was having problems with the code running on the Pi which didn't happen on my laptop running Ubuntu 17.04. I strongly suspected the problem was the old version of Sqlite3 or Python3 in that Raspbian distribution so decided to upgrade to the latest Rasbian (2017-11-29, based on Debian 9 Stretch rather than the previous one which was based on Debian 8 Jessie).

During the installation on the new system I made notes of what I needed to do to get my code running. For my own future reference and maybe of help to others, here they are.

Nailing where there isn't room to swing a hammer is awkward. Here's an idea.

Funnel Cloud

Not something often seen in Caithness but there was a nice funnel cloud off to the south west of my house site this morning, just after 11 o'clock.

Seven Up

Well, the digger arranged for Monday indeed wasn't available. It's a brand new one which went to the Black Isle show last Thursday and was supposed to be delivered to the builder on Friday but didn't actually arrive until Monday evening.

The forecast wind seemed to slip back through the week and reduce so I arranged for it to come, for its first outing, today (Thursday).
