OT: Programming Languages

John May made the point that in LTSpice trapezium integration (as opposed to modified trapezium integration) give less distortion in the simulated waveform. Numerical integration is a good way of accumulating rounding error, and shorter words mean more rounding error.

Closed loop feedback takes a while to settle. If you known what you are doing you can mostly make the settling dead-beat, but sometimes this costs you more performance that you can afford.

Then it stops being a linear component.

Non sequitur. The simulation program involved - LTSpice - does accommodate capacitors, but you don't need to add them to the circuit being simulated to do what Edward Rawde was asking for.

Cursitor Doom likes his world views thoroughly bizarre, if not downright absurd. One of the more bizarre aspects of this behavior is his delusion that he can pose as the voice of reason, and not get jeered at for his lunatic pretensions.

The fact is that a 1fF cap would have had the desired effect without compromising the circuit's performance. Why do you feel the need to complicate everything? Oh yes, to show us all how clever you are....

Edward Rawde wasn't asking how to stabilise the voltage difference. He was asking how to display the small short term variations in voltages on the screen in the presence of a large voltage difference - the P-channel and N-channel FETs in question were operating with their gates a couple of volts above and below ground respectively and he wanted to see the mV difference in gate voltages through a single cycle of the sine wave.

Knowing what's actually going does lead people to tell more complicated and realistic stories than those dreamt up by fantasising twits like you.

Realistic stories tend to be quite a bit more useful, but you wouldn't know about that.

Talking about structural "elegance" in my opinion (Common) LISP is one of the best. Data, structures, functions, even programs... everything is only atoms and lists.

His world view is that he knows everything and everyone else is stupid so deserves insults.

That's really sad.

rsions just get in the way.

I had to laugh out loud when I read that because it's *so* true. The condescension in particular is off the scale. It's a wonder he deigns to talk to anyone at all! But his limited vocabulary gives him away every time. Have you noticed how fond of the word 'fatuous' he is? That's his go-to insult for just about everything.

Best to ignore him.

Absolutely. And I shall do once again when the sham election is finally over and Kamala Harris declared the winner.

Best to ignore her too.

John Larkin is a narcissist, and that has to be read as saying that I think I know more that John Larkin (and I sometimes do) and he feels insulted when this made obvious.

Narcissists have a lot to be sad about. Look at Donald Trump.

You could go to the Digikey website and look it up for yourself. Digikey Australia doesn't seem to stock it.

Digikey in America lists an NXP part with a similar part number, but shows it as "no longer in production".

John Larkin may be able to do better, but he didn't post a URL.

Maybe he was relying on his memory of previous purchases. Not wise at his age.

The 8 was a klunky machine, 12 bit, page addressed, one accumulator, no stack. HP and Data General followed up with 16-bit versions, equally klunky, but the PDP-11 was a much better architecture. It was apparently designed one night in one beer session, with Rick Merrill (the inventor of Focal) having a lot of influence.

See Digikey!

They show various MC68332 parts from about $20 to $50. Being Digikey, they only stock the most expensive ones.

We will need to redesign a bunch of older products as parts go EOL, but the 68332 has outlived about 5 generations of various ARM chips already.

...

Haven't used one for 25 years and yes I bet plenty of people will be panicking over what to do when they're no longer available because the original designers will be long since gone.

I'll be rich, then. I've got hundreds of them. :)
