I still believe Air Marshal Arthur Harris should have been on trial as well at Nuremberg.

There also should really be a Linus Torvalds status somewhere in the world by now.

I want Bullet Trains, but I'm definitely an outlier American on that.

I'm in favor of free and fair elections. I guess that may make me a screaming liberal these days. So be it.

On my bucket list! In the 1970's my family traveled Europe and the WW1 U-Boat at the Deutsches Museum in Munich left such an impact that I made sure to revisit in the 1990's while traveling to Israel for work. Truly amazing engineering for the time.

Way Cool! Das Boot is one of my favorite books.
The movie? Well, it's excellent too.

It hits home too. When "Carol" asks "Pirate Lady" (Zosia) a question, it reminds me of my daily correspondence with ChatGPT / Copilot AI LLM. The whole world collective knowledge through a single funnel.

I'm still very much enjoying it. The S1E3 hand grenade going off inside the house would have been more believable in terms of damage, but whatever. Rhea Seehorn is fantastic. After Better Call Saul, glad to see she landed star casting in her own show. Like Severance, it's new and fresh writing.

RE the book plate offer - still can't DM on either platforms. You appear to be blocked all around.

Thanks! For 2026, I'm attempting another manuscript. RISC-V System On Chip (SoC) design with Verilog and bare-metal C.

OMG - Breaking Bad and Better Call Saul are The Sopranos, The Wire, and Game of Thrones level of Television.
Very much worth the time investment.

I seem to recall a story about spending every last dime on a ferry ride to Nantucket or something to see friends with no means of getting to their house or paying for a return ferry home. Now that's how rich people travel.

Which gym, "24 Hour Fitness" maybe? I stopped "Anytime Fitness" when COVID hit. I'm just using the company gym these days, which is great. Lonely, but great.

A fallen tree was completely blocking my green-belt hiking path this morning. The funniest thing is there was no broken stump in sight. It's like the wind carried half a tree some distance.

Global clock buffering is generally difficult to implement - when you turn off your main clock, who turns it back on?
Regional clock buffering though is incredibly effective and easy to infer with modern synthesis tools. I make use of inferred regional clock buffering as much as possible.

The amount of load capacitance the clock input of a CMOS flip-flop represents. The C in CV^2F impacts power just as much as the F. It's easy to forget.

I enjoy the learning new things and fast-free writing blog stage. The final refinement into a book can be a grind. It's worth it at the very end of course.

System on Chip design in FPGA fabric using the RISC-V open-source CPU architecture out of UC Berkeley. Like my first book, it's starting out as an open-source blog series where I do all of my research and just free-write as fast as I can. Book comes after. blackmesalabs.wordpress.com/2025/08/31/b...

Thank you. It feels fantastic! There are, of course, some things I would like to slightly change - as seeings things on paper versus a computer screen is a bit different. Water under the bridge though. I'll make those improvements on my second book!
