I kind of give up these days, anytime there is bright sunlight it is hard to see. And when I look at my Kindle Paperwhite, I just wonder if there is a better way. Well, it turns out they are niche products, but e-ink (which is a patented technology) is…

Ok, if you are setting up a large installation and have to use wired because the system does not support wireless for things like GPS RTK systems or there are jitter problems on WiFi, then you are going to need some long-ass cables. So how long can you actually go:…

OK here is a strange error. I hope you do not get this. Occasionally, our Unifi Dream Machine flags a push to GitHub as an information leak. This manifests itself as hang when trying to do a git push or git pull. The fix is pretty simple (although the Unifi…

OK, it used to be that you would just dump anything you don’t need into the garbage and it would find itself in a landfill. Well, we are far from those days, today, every day there is regular waste, there is green waste and there is recycling plus lots of…

Do you know how sometimes one thing leads to another? In my case, it started with climate change which leads to 90 degree plus days in Seattle which leads to wanted to sit outside instead of swelter indoors which leads to wanting to write some code outside which leads to…

We have a WaterCop system at home from the ancient days before Apple HomeKit and also an old lighting system. The first one has false alarms and we can’t ever tell which sensor actually triggered since they all feed a single sensor into the alarm system. The lighting system has…
