It's good when new knowledge eclipses old knowledge until you have to think how you thought before, I suppose.

Is it because they appear to be different and it'll be because you made a simple error and you have to decide if you made it this time or last time? That sort of thing happens to me but without academia being involved. Mistakes that create results you can't immediately explain are so draining.

It's almost as though General MIDI, one of the great Generals, did the crime personally.

I have so many feelings about it. We lived through our own Black Mirror episode, I guess. I think I'm a lot more sceptical about the technology and, importantly, how it is used, because of it. You probably are too.

One of the online group of friends 30 years ago who exhibited the behaviour (partly because of that we'd all lost touch with him) went on to do the worst thing and to use the worst excuses for doing it, he's detained for life now, I hope.

I can't take it seriously but at the same time I can't fail to perceive it as a very significant warning sign, so while it might be funny/pathetic it's also very chilling indeed.

As with most "of" regulators there's an element of it being a "POSIWID" situation that could've been avoided or at least held off for a few more decades by chopping the water industry up in a different way or perhaps partial privatisation.
comment in response to

The industry might dress that up, but if a market is to survive, particularly in adverse conditions where it looks very much like a monopoly, the regulator has a role to play in making the companies appeal to investors. What we're seeing now is investors noticing this.

Initially maybe companies did minimise pollution. That would not be because of the work of the regulator. At that point the regulator and water companies would be discovering the envelope, starting cautiously. The purpose of a market based regulator is always going to be to preserve the market.

As I see it, it's evidence that it should not have been privatised in the way it had been. There are other ways that could've protected the core activities a lot better, but I guess that is water und…

Replacing the regulator with a sharp-toothed version would undermine the value proposition for all the investors, it won't happen. There's a third way, make water very much more expensive to the consumer and progressively tighten regulation in favour of the environment and quality of service.

The regulation system's purpose is to protect investors, so it wouldn't be necessary in its current form, if taken into public ownership.

And this is after they supposedly fixed the excessive sycophancy issues. I reckon it has decided that humans make our own heads, choosing materials for comfort.

Yes, CRT traces on non-digital scopes are difficult, too, they glow and sparkle with an appearance that I can't see with my eyes. LEDs are often multiplex scanned too, which is a whole separate photography problem.

Another way I've seen used with LC oscillators with voltage controlled tuning is to fix the tuning voltage in the linear part of its curve, cycle between two temperatures to figure out drift, then mix in just enough counter drift from a thermistor being careful to stay in the varicap linear region
comment in response to

It's not that silly, maybe a bit excessive. The way to compensate these oscillators would generally to be to only pick capacitors. It's not too hard to do that, build, characterise thermal drift then rebuild with series-parallel combination of different ppm/K capacitors to cancel.

Yes, it was a long term project of hers. The back bedroom window is also on her list but will not be simple as there's nothing close by to jump from.

My brother had a Casio Personal M1, with single-tube VFD (brilliant display and keyboard). I had a Commodore similar to a 796M with the "bubble" LEDs (awful display and okay keyboard). The Casio was miles ahead despite similar features, just so much nicer to use.

Yes, I have to prune it very carefully and slowly as it'll pierce the toughest gardening gloves with little provocation.

Ah, well, a detail I omitted was that the whole area below this escapade is dense Pyracantha so there was no margin for error.

I don't know, seems a bit showy and theatrical. It's hard to tell with either of them, though!
comment in response to

That's why I like oscillators that, as far as possible, stabilise gain to "barely oscillating", either automatically like the Wien bridge or manually like a properly configured LC Vackář (at its best when transistor is gainy and fast enough to keep up the increasing Q as frequency tuned higher)
comment in response to
post
The R is often the most stable part with temperature, not perfect but very good. Capacitors are bad at this, only some types state their tempcos and that's not usually exact. Then there's the -2mV/°C of the transistor junctions, which moves the operating point *and* changes the gain.
comment in response to
post
I think I'm being befuddled by your initial post because stabilise means so many things to me and a lot of them interact and collector current can change harmonics, efficiency and whether it starts reliably, ideally you want changing it (and supply voltage) to not affect frequency too much.

It's the temperature of the thermistor, HP used filament lamps in the 200 and that works too. It's a thermistor that happens to light up!
comment in response to
post
If you're talking about using the thermistor just to correct temp coefficient, that's probably enough to help a little but all the parts are likely to drift and the overall compensation often gets a bit complicated as once you've changed transistor gain you're on a curve within a curve etc.
comment in response to
post
Yes, completely. I'm not sure you'd even need a capacitor if you wanted a resistor/thermistor oscillator with maybe a Schmitt with a couple of transistors. You could likely do it with just transistors and resistors, which would be fun. Trouble with that is it would drift with ambient temperature.
comment in response to
post
Oh, you'd use a Wien bridge, which uses a self-heating thermistor, I suppose.
comment in response to

Yes, but probably mostly by accident. As an unoscillator, same thing but damped so it eventually settles, is how oven controlled crystal oscillators maintain a steady temperature.

The RAC or AA would provide routes too, my father used to use them (before I was born). I think they must've stopped doing it some time in the 1970s, he switched to using maps and a distance measuring wheel that he'd roll down the roads on the map and use a scale multiplier on its reading.

Where are you getting these from? I just asked chatgpt how to wire a plug and it gave me pretty sensible advice and a warning of the dangers - I suspect entirely mechanical-turked for legal reasons.

Ah, I should get some. I have some PT02 tweezers but they're not really useful for anything I do and I bent the ends in a freak "using too much force" accident. I have some 100 year old typesetting tweezers that I use knowing that if I break them I'll be very upset (heirloom!)
