John Koza has something like three or four books on Genetic Programming. It's all in Lisp and I enjoyed working with different examples from his books. If I ever have enough free time, I'd like to go back and work with it again fo

Thank you for taking the time to drop this link. I had exactly the question I think you anticipated: "Where can I get a really well-made washer and dryer?"

Here's my take. Asserts are a kind of error handling. They handle situations where the code can tell that it's off the rails. It might be off the rails due to a hardware error or a software implementation error, e.g., a 'can&

This has been exactly my strategy when writing software for medical devices, in my case, ultrasound systems. You have to help other developers understand how and when to use asserts, and then you have to test the developed device very well,

Yeah, I was thinking of a different book. Here's the link to the other one: https://www.amazon.com/Object-Oriented-Programming-COMMON-LI...

I have had this book for many years. I remember the toy expert system ("Otto") and enjoyed learning from the example. If I remember correctly the author makes good use of CLOS in the book.

Looks neat and I'd like to try it. I wonder how well it would work from within a GNU Emacs shell buffer (comint based, I think) running bash. Has anyone given this a shot?

Yep. My 2012 Tundra still runs well and looks good. The only issue is that over time the steering wheel has been polished smooth by all my driving over the years. I am at 160,000 miles and expect to get to at least 250,000.

I was somewhat reminded of Larry Wall's newsreader, 'rn', as I read the description of Orange Site Hit. I invested a lot of hours on Nutnews back in the day.

I hope the following from Wikipedia is helpful: The computer had 2048 words of erasable magnetic-core memory and 36,864 words of read-only core rope memory. Both had cycle times of 11.72 microseconds. The memory word length was 16 bits: 15

Wasn't familiar with RACI acronym: RACI is an acronym derived from the four key responsibilities most typically used: responsible, accountable, consulted, and informed. It is used for clarifying and defining roles and responsibilities

Same. I love the idea of ditching the Proton Mail bridge app on my Macs. It's been a frequent source of configuration and update headaches for me.

This has been my take as well. There is a lot of disruption in a company when a key part, like the FPGA that serves as a communications nexus in the product goes EOL and everyone scrambles for a year trying to engineer in a replacement. Buy

Can you say a little bit about the possible risks from hot silicon being in contact with the water? I have not heard of this before.

I asked ChatGPT 4.0 what LMR meant as applied to coaxial cable. It gave me an excellent response, including that LMR is a trademark of Times Microwave Systems. I rarely use search engines anymore. I'll bet the same is true for many peo

Snap-On tools are great. They also cost an arm and a leg. Yet if you put a 3' pipe on your 1/2" ratchet and break the ratchet, the tool guy will fix it or replace it on his next visit.

Following up my own post, I also remember the hardware guys having occasional phone calls with some guy known only as "Larry" at Intel. I'm guessing he was a microcode guy or some such. Would be interesting to know more about
