After doing some slight maths followed by even slighter maths assigning the cost I realized that I was perfectly a-ok with a beta-unit of a fence. This is of course still heads and shoulders above the omega-non-unit that is a standard stick-in-the-mud fence. As was demonstrated Read more…

We’re interested in the load generated on the post above the ground where the fence attaches to it. This will also play into the footer design later. The way fence post loads are calculated, and I swear I saw Read more…

My home AC has been operating (fitfully) under the control of my system for a few weeks now. While doing so it has also been logging various parameters at one second intervals. I thought it would be interesting to look at the data. The first question was: what is maximum attic temperature. Since all of the data is in a Postgres database, that’s a very easy question to answer: bbb_hvac=> select max(attic_temp) as temp_f Read more…
