Yes, emphatically agree. Thinking is key, being with a problem. And it is maddening to mediocre technical managers to not be able to somehow see that an employee is working, that progress is made. My father got exasperated at me when I was working on a design because I sat at a desk and drew schematics, but sometimes just sat there and thought about things. He was very partial to circuit compendia like those doorstop collections edited by Graf and others. And at the bench he did love decade boxes

I've thought that one of the most curious aberrations in the direction of supposedly eliminating thought was "genetic" programming. I'm not sure how well it's doing lately, but it was heralded as the next big thing for a while. I can still recall the picture of one of the proponents, sitting at his desk with a grin that spoke volumes about his smug self-satisfaction.

One of the "triumphs" I recall claimed was a high-order filter. In the wiki, electronic designs are mentioned but with no clickable links.

There is this creative-commons free reference: A Field Guide to Genetic Programming

I totally agree.
Personally I always use paper and pencil (and calculator) when I'm working with a new circuit, before I simulate the circuit.

I need to get more exercise in the winter.

Does Running Late count as an exercise?

I used to have an office where I could put my feet up on the desk when i was working (thinking). I did this frequently... leaning back in the chair with my feet on the desk. That picture apparently wasnt a good one for those passing by the door. I soon guessed (with help) that you had to "look" like you were working..... thus came the Look Busy phenom. that has taken over. You know --- Gods coming! Look Busy! -RNM

Nothing will drive a mediocre technical manager to suicide faster than to do a lot of thinking in the beginning of a large project. A large project which has a funding time limit... a drop dead date. When the project must be completed and working properly. There you are doing 'nothing' (but planning, solving problems and getting organized, writing sole source procurment reasons, prioritizing, contracts etc). meanwhile time is passing by and that manager is going to get on you to take some 'action.' But when your project does really launch... it goes fast and smooth and you look like a miracle worker in that poor managers eye. And, he looks good, too. :-) -RNMarsh

A joke, I get it!

Just how do you turn the big Windows/Intel uPC ship around? Or, are there alternatives (mini-cpu) that are affordable, PNP, for personal use that I dont know about? What cpu do you use -- and software?

I used to have -in my home- an LSI-11 (RT11 OS) maxed out mem and drives of the time..... math coprocessor and the works... efficienct codes and less operating overhead made it do FFT very fast. I used DADiSP software at home ... still available for PC too. Look it up. Superfast -- I could change part values on the schematic and see the bode-plot etc in real time change in the other window. In fact I could have a dozen windows open on the display screen and see the effect in each window's plot of what-ever change made in one window. You dont need a tonne of memory to do this but efficient code and cpu designed for number crunching (eg 'scientific'). And, it didnt use windows or linux... all machine code.
BTW - these number crunching machines are misleading when you compare memory size needed to get work done with todays x86 derivitive machines. The many layers of code and switching data I/O of mem is the best reason to change over to SSD. You'll think you just got hooked up to a Mini-cpu machine. really. Thx-RNMarsh
There is no reason that you cannot run machine code on an X86 box

Some of the engineering software used on the PC uses only the GUI interface and under it all is a seperate OS running the show or in machine language. Such as DADiSP, I mentioned. Originally, DADiSP ran under DOS while the front end looked like what ever Windows that the machine came with. Seems the more you can get rid of Windows OS etal the faster everything becomes.

Hardware and software improvements will optimize what we have to work with. Then add SSD.

Thx-RNMarsh
