This was a fun project, which took me way more than I hoped.
The ultimate Ping machine pings the Internet, displays ping time and monitors WiFi.
Inside, ESP32 configured using an Access Point and captive portal allows setting IP addresses of monitored servers.

Today's thrift shop find: Commodore Minuteman 3 ca. 1973.
How tiny this thing is! (see AAA batteries)
Finally term "minuteman" has a different meaning from ICBM.
"A 'minuteman' (hist) refers to a member of a colonial militia who was ready to fight at a minute's notice, especially during the Am Rev"

Researchers at the University of Utah have found a tape that appears to hold the only known complete copy of 1973's UNIX V4.

Whenever I see Cybertruck on a road, it feels like there is some Universe crack opening.
While I understand a need for a disruption, this thing seems to be made for individuals who say "fcuk you all" to everyone else.

Temporal Anomaly Clock.
The clock shows time with its local anomalies.
The sensitivity is set to 5 but "it goes up to 11".
I did not dare go set it that high.

Interesting psychological implications of interacting with AI.
The news talks about people having "relationships" with AI, which seems possible given the human capacity for, well, anything.
I try not to anthropomorphize AI, but I caught myself doing just that.

Asked Gemini to replace print() with logging in an old Python script. It did, but then started refactoring my code unprompted. When I asked WTF, it replied: "I apologise. I got carried over..."

It is official: I hate GIT.
It is overcomplicated with questionable teminology, and I failed to learn anything beyond basics.
Bad merge left my code like a pile of streaming s**t, and I can't check out develop branch.
What are my options? Spend two hours fixing the code?
