I wanted a new logo to go with my YouTube channel to replace a very old photo of me. So I asked ChatGPT and it didn’t let me down!

John’s lab
Updated the photos of my lab. How many cameras can you see?
Pencil sharpener
I’ve just played a round of “If John owned a pencil sharpener, where would he keep it?” — but I didn’t win.
Amphetamine
I wanted to know how to stop my MacBook Pro from going to sleep when I closed its lid, so I asked ChatGPT and discovered Amphetamine. Good work, Internet; you have come a long way since the nineties.
p.s. I always wanted to blog about amphetamines.
Keyrings
It is well known that I am a nerd. But if there were any doubt, this removes it. :)

Just preparing my lab cameras. This video is a bit sketchy because I made some mistakes during recording. But it is what it is. Hi! :)

Installing Vim on FreeBSD
I was fooling in my new OPNsense router and needed myself a copy of Vim. Learned I could install it on FreeBSD (on which OPNsense is based) using the `pkg` command:
# pkg install vim
Computer coffee table
Here’s something fun. I had a computer sitting on the floor in my lab for a few months while I waited for some parts to arrive so I could service it. In the intervening time I discovered that it was rather handy, and functioned as a small “coffee table” in the center of my room which was good for storing books and magazines on. So I taped some cardboard to the base (for when I stub my toe on it!) and have kept it as a permanent fixture now.
Network v4
I have redone my computer network in its fourth (and final?) incarnation. Everything got redesigned from the ground up. You can see some of the (color coded!) cabling here:
The two switches on top (GREEN and ORANGE) support speeds up to 2.5 Gbps, whereas the bottom two switches (RED and BLUE) only support up to 1 Gbps. The white cables on the right are spares, they’re just auxiliary cables which have already been installed and are available if I need them in an emergency.
