My first home automation script worked! On Saturday, I wrote an “at 0600 on weekdays, turn on the lights” script. On Sunday, nothing happened. On Monday, the lights turned on! The script:

Me Casa es Su Kasa
My goodness but [expletives deleted] lightbulbs are snoopy! The Kasa “smart” lightbulbs want to know everything about you to upload into the Kasa cloud app, which of course requires setting up an account. Want to guess my password? Hint: It’s the title of this post. Thankfully, once you get them WiFi-ed, you don’t need useContinue reading “Me Casa es Su Kasa”
sudon’t
sudo is a Linux command that gives one administrative privileges for the following command. There wouldn’t be much point in it if just anyone could use it, willy-nilly, so there is a list of users allowed stored in /etc/sudoers. One must “sudo” edit this file or, again, there would be no point in it. InstallingContinue reading “sudon’t”
RISC vs CISC
RISC (Reduced Instruction Set Computer) and CISC (Complex Instruction Set Computer) are two different CPU architectures. Their names pretty much explain the difference. The argument over which is “better” has been around forever. When I learned VAX assembly language, I remember being impressed that there was a single instruction to evaluate a polynomial. Granted, oneContinue reading “RISC vs CISC”
I’m Not Dead, Yet
The hot tub is not only filled, it is hot. It hasn’t killed me, yet. I did kill my network swapping out the firewall. Tip: It doesn’t matter what your iptable forwarding rules are if IP forwarding is not enabled. Next steps: Renumber the virtual machines and add the names to PiHole.
Tech Update
The cluster is sitting there doing its thing. I figured out why Cassandra is such a memory hog: It queries the system memory when it starts and allocates 3/4 of it. Oh sure, there is a limit: 18GB. I haven’t done anything about it, but now I know. The stuff I’m writing that uses theContinue reading “Tech Update”
I Can Quit, Anytime
The bottom glowy bit just arrived. I think it adds a nice symmetry. There is no such thing as RGB addiction. Really.
Cross Disciplinary
This seems to fit me. I found it at the PowerLine week-in-pictures, so I have no idea how to attribute it. And there is a word for words that are spelled the same but pronounced differently (e.g. “record a record”), but I don’t remember what it is; “grafonym” or “homograf” maybe? I had never realizedContinue reading “Cross Disciplinary”
gogs up
gogs is a “GO Git Server” that (supposedly) runs just about anywhere. It runs fine here. I wanted source control locally, and a bit more “control” than just a git init local directory. There were a few issues: I wanted the repository directory to be on a guest/host shared directory/folder (so Windows backups would getContinue reading “gogs up”
Computer Speakers
Those count, right? Very non-stereo, but there is no room on the right side of my desk for one of those. There will be upstairs – I’m building it into the desk space; they’ll hang on each side of the monitor. As always, it was an adventure with a simple solution. Why do they alwaysContinue reading “Computer Speakers”
