ChatGPT tells me about Insulation-Displacement Connector cables, such as these.

RTL
The initialism “RTL” can stand for both “Register Transfer Level” and “Resistor-Transistor Logic” as explained by ChatGPT.
Critical Path != Critical Section
I always get the concepts “critical path” and “critical section” confused.
The “critical section” is the part in your algorithm which you must hold a lock for; whereas the “critical path” is an idea from hardware design which relates to the time taken for the longest combinatorial logic that needs to be processed during a clock cycle, thus limiting the frequency you can run your clock at.
Although the terminology “critical path” came from hardware, the same terminology is used in software. ChatGPT has a fairly good write-up on the two uses of the term “critical path”.
I learned a little more about this in Introduction to VHDL for FPGA and ASIC design.
CRC
I watched Ben Eater’s videos How do CRCs work? and Checksums and Hamming distance (the full course is Learn about error detection) then found the Wikipedia page: Cyclic redundancy check.
Also of interest:
BPS BB830
These BB830 breadboards are the ones Ben Eater uses in his videos.
HP-16C
I was watching Ben Eater’s video Build an 8-bit decimal display for our 8-bit computer and I was interested in what calculator he was using. Seems to be an HP-16C.
Breadboard wire
You know you’re procrastinating when you find yourself organizing your breadboard wire. :P
That drawer I have is an gku™ Underdesk Keyboard Drawer under desk keyboard tray and storage AC1009.

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! :)

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.
