It’s the 4th of July weekend and the beginning of a birthday week/month for me. With all that to look forward to, I can’t seem to get motivated to do…anything. I had a productive day yesterday, but today is a bust. Total couch potato.

The weather in Socal is perfect right now. Sunny and cooler than normal for July. Still bone dry, but at least cool. Even so, no fireworks in Fallbrook tonight – have to go to the coast to see those. Too much fire danger inland.

I’m getting burned out on reading – maybe I need to start writing again. Next weekend’s Imaginarium conference oughta be a good catalyst.

About to get hot

I’ve been looking forward to my trip to Louisville. Then I looked at the 10-day forecast. Yikes.

That’s ugly. 90+ degrees and 70+% humidity every day.

Had an interesting discussion about bitcoin and cryptocurrency in general with a couple of friends last night. It got a little tense, as the only way I could answer certain questions was with deeply technical concepts. I mean, how do you explain that this particular cryptocurrent (bitcoin) isn’t really encrypted, but uses the Elliptic Curve Digital Signature Algorithm (ECDSA) to sign (assign ownership) a coin? Anyway, this morning I found a good article that lays it out in mostly-plain-English terms. Bitcoin and crypto have become semi-religious topics for a weird mix of conservatives, criminals, investors speculators, and anti-government types. They believe, but they don’t understand the details. For me, the only detail worth remembering is that cryptocurrency (especially bitcoin) is a Ponzi scheme, suitable for speculators (gamblers) and not much else.

Speaking of technical, I really enjoyed this article comparing the Apple M1 and M2 CPUs. 20 billion transistors for the M2 – that’s incredible. When I entered digital tech in college, we worked with the Motorola MC6800, with a whopping transistor count of 4100. The M2 has five million times (!!) as many transistors as my old 6800. Makes me feel old…but proud of my fellow engineers.
