Sharing PCB designs on PCBWay
Over on An Absolute Beginners Guide To Designing PCBs using Easy EDA – Make PCB From A Schematic I learned about How to Share Projects in PCBWay Community. Seems like a good service to me, haven’t used it yet but do intend to check it out.
Floor upgrade
I kept dropping components on the floor and was then unable to find them on the black surface. So I’ve resurfaced in white, let’s see if that helps.
Relational Theory for Computer Professionals – C.J. Date
I was watching Relational Theory for Computer Professionals – C.J. Date and he made this fun remark:
There’s only three databases in the world: there’s departments and employees, there’s courses and students, and there’s suppliers and parts.
Costume
I was chatting with my brother about my new video blog and he said I should do something to make myself distinctive, so I thought a lab coat, ID badge on lanyard, and pocket protector full of tools would do the trick.
To that end I got myself a lab coat, set of five multicolored lanyards, a pocket protector, and a screwdriver with clip.
Cosplay! I’m such a nerd. :P
My inspiration was mostly Stetmann of StarCraft II fame, although my outfit isn’t exactly the same.
I made some ID badges for myself, I figured I could give myself various job titles and choose a different one from time to time…
Golden Ratio
ChatGPT explains the golden ratio.
New look
After around 12 years with a completely unreadable look and feel I have finally bowed to pressure and switched my WordPress theme over to something sensible. I’m using the Twenty Eleven theme, which is what the old unreadable theme (known as OldSkool) was based on. This change is as a courtesy to my readers, who I do actually value. :)
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.
