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:
Keyspace on the back of an envelope
One question that always plagues me: should I use 32-bit or 64-bit keys. I can never make a firm decision on this point. But I’ve just done some back of the envelope calculations in thinking about it.
If you issued one identity per second, every second of every day, it would take 136 years to exhaust the keyspace.
If you issued one thousand identities per second, it would take 50 days to exhaust the keyspace.
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.
YouTube channel logo
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.
