Usually when I start a video I say “You’re in the lab with your mate, JJ”, but YouTube’s speech to text picked it up as “You’re in love with me, JJ”. Also on another video it says “Screenlab with Mike JJ”.
lol. I guess YouTube doesn’t speak Australian! :)

In this video I let people know about the current network outage which I am working to resolve as quickly as possible. Also I’m interested in people’s opinions about how we cover the Learning the Art of Electronics coursework into the future.

I am in the process of rolling out the fix for the recent PHP vulnerability. So far, so good. I hope to have my websites back online soon. Sorry for the interruption.

This is a part of the homework feature of my blog, which is an ongoing conversation with my mate S.F.
Hey mate. Lovely to see you again, as always. Can’t wait to do it all again soon!
Two interesting movies I’ve seen lately:
The prompt for my breathing timer which I gave to ChatGPT, was: “please create a web page for me with HTML and JavaScript that I can use for breathing techniques. I want two modes: box breathing which is in for 4 seconds, hold for 4 seconds, out for 4 seconds; and 4 – 7 – 8 which is in for 4 seconds, hold for 7 seconds, out for 8 seconds. I should be able to pick the mode I want and then the app will prompt me with timers about what to do next.”
The hard problem of consciousness is one of the most profound unsolved questions in philosophy and cognitive science. It asks why and how does physical activity in the brain give rise to subjective experience? In other words, why does it feel like something to be conscious? I’m not sure of course, but it seems to me that the capacity for memory is tied up with consciousness, inasmuch as we don’t seem to have memory without first having been conscious.
Cartesian doubt is a form of methodological skepticism associated with the writings and methodology of René Descartes, the idea being that we can find things which are indubitable, that is, beyond doubt. Descartes famously found “I think, therefore I am.” That he could think was an indubitable fact. I have a similar thing which I like that is: “I know that I am having a sense experience”. It’s kind of along the same lines but includes more primitive conceptions, such as knowledge, time, identity, sensation, and such.
Conclave (2024) was an interesting film about the election of the pope. It’s fiction and you don’t need to be a true believer to enjoy the movie.
We mentioned about Pamela Anderson, and her movie Pamela, a Love Story is on my list. Pamela was at one point married to Tommy Lee of Mötley Crüe fame.
You recommended The King of Kong (2007) and I recommended Ready Player One (2018).
We discussed the Pareto distribution which is a type of power law distribution. These types of distributions can mess with our intuitions because they are not similar to bell curves or other less extreme distributions. The Pareto distribution gives rise to the “80:20 rule” where 80% of outcomes are for 20% of causes.
This is a note for Future John. Today I got two new RM12-9HR REMCO VRLA Batteries for each of two PowerShield Defender 1600VA UPS systems. The RM12-9HR batteries are 8.5 Ah 12 V batteries I paid AU$65 each for four of them.
Today installed my replacement UPERFECT 4K Portable Monitor 15.6” UHD IPS 3840×2160 USB C Monitor HDR FreeSync from UPERFECT. This is a small form factor 4K display which I use as the third 4k monitor on my primary workstation. I use it for displaying notes and reference material, mainly this:
Today I learned about Gabriel’s horn, a solid of revolution with infinite surface area and finite volume.
I watched this great movie Perfect Days recently and learned about the Japanese word “komorebi”, it refers to sunlight filtering through the leaves of trees, creating shifting patterns of light and shadow, unique and beautiful in the moment.
Today I reached 3,000 subscribers on my channel, @InTheLabWithJayJay. Pretty happy about that! Next stop, 4,000.
