Not very much more came up, but I found at least two other interesting articles. One was about the source code for a PDP-8 emulator which could run on both my old Elf and the Zwölf on the breadboard. And there is a complete implementation of floating point routines that also would work on both. Zwölf does not have anything like that, so I might adapt and include this one.
And there is also a reference to an article about some kind of hardware support for indexed addressing for 8080 based systems. It was only mentioned in a letter from a reader and he thought about doing the same to the Z80s, 6800s and 6502s of this world. His comment regarding the CDP1802 makes me even more curious: WHAT FOR??? That could mean that he understood the little 1802 only too well, or possibly not at all.

... to get rid of all the hideous manual memory management I was using. (It's written in C++, and yes, I know I never should have done that in the first place, but let's just say I'm older and wiser now).
Anyway, I just wanted to share the fact that I'm down to ~2500 compiler errors and counting. Things are looking up. It'll be interesting shaking out the bugs though, it actually worked just fine before the big hackathon of Spring '22.
Also, just for the benefit of you C++ hounds, I find myself in an interesting position. In order to support the various platforms I want to support, I am limited to C++14 (which is actually not too bad) but, on my feeblest platform, the STL only supports C++03. That means no 'move semantics' in (most importantly) std::vector so I have rolled my own and plan to put up an article or two about that when I get my head above water.
So take cover! You have been warned!  And now, back to work

2500 compiler errors? Damn!
It's amazing what an extra close curly bracket can do, isn't it?

Or worse, an extra one - then pretty much everything after it throws a compiler error.

Is a moral or ethical discussion about coding too spicy for this forum? Here goes nothing.
I've checked out of platforms that boost posts based on "engagement"
I rarely visit, and no longer participate. I don't have a usable facebook or twitter account.
I do it for the same reason I've cut most advertisements and branding out of my life - to the degree that is possible in the consumer-centric society in which I live.
It's mind pollution. It's a psychic vampire. It eats joy. It makes you angry. That's the point. Anger keeps you "engaged" more than just about anything, so these platforms boost those posts.
It's promoting toxicity algorithmically. I think its messing up our social cohesion and our ability to be rational, at least as a whole if not specifically in the individual sense.
It's one of the darker sides of modern innovation in software development. Sometimes I feel like we're in the same moral or perhaps ethical predicament as say, physicists, who can use their knowledge to create things like weaponized nuclear fission, or they can use it to improve our lives. I don't think anyone involved at that level with something like the Manhattan Project did so without deep reservations about what it meant for our collective future.
Is it the same thing? Perhaps not, but can you really measure the damage we're doing with some of things we help create?
I think about this stuff when it comes to the projects I'm willing to take on. I try - at least by my estimation - to avoid projects that aren't socially responsible.
I think given the social landscape, at least in the divided country in which I find myself, after understanding some of the reasons we're in that situation, I don't want to be part of the problem. I won't be, at least deliberately.

No wise response here, simply, I agree with everything you wrote.
And yes, IMO, weaponizing nuclear fission (and many other things) vs. "weaponizing" software to coerce everything from consumer purchases to who we vote for, it is the same thing, and the damage we're creating with software is considerably more difficult to measure in terms of psychological and social effects. There is some good, for example, some of my diabetic friends on social media, whom I did not know were diabetic, were very helpful in helping me help my mom when she was diagnosed with diabetes. I think that's the dilemma -- while one can argue that a "weapon" can act as a deterrent, it is designed specifically for destruction. It's more complicated with software -- it can be designed with good intentions but is easily "weaponized" (without a line of code change) for unethical activity. Even worse, it can be used as intended but there are social and psychological effects no one understands.

HtC - you are spot on. I also do not use social media. Who needs the extra stress?

Totally agree. And I must let you know, I only saw the subject: Psychic drain Pin, and I thought of you that same moment!
Advertising in itself is just mind pollution, so that is a bit evil, but not as evil as this algorithmic feed generation that amplifies groupthink, division and aggression. The question of where to draw the line to morally unacceptable is a tricky one.
ATM i am involved in creating a server that creates scheduled web-TV channels from recorded assets. Our customers want offer these TV channels for "free". But they will make money from unskippable advertising in these channels. We are not involved in the (client side) unskippability. I do not think it goes beyond the morally acceptable, but nor do I think it will boost my karma...

The use of anger to engage and control isn't limited to software-based social media, and it isn't a new phenomenon. It's as old as the printed word, and older still in the hands of politicians. The technology is just making the medium more efficient.
To create that anger you must create enemies for the people to hate, and it's handy to have a few enemies to blame, to direct the anger at, both external (Russia! China! Mars! California! Alabama (roll tide!)) and internal (Liberals! Conservatives! That religion! That <name any ethnic group or any group of like-minded people>!). Anything to distract us from what they're doing to stay in power and/or make more money.
Tyranny finds a way, and our "civilized" first-world countries aren't immune to it. I'd suggest we're more likely to serve several different tyrants at once.
If you think 'goto' is evil, try writing an Assembly program without JMP.

To be clear what I think makes it different are the algorithms, because you're right - it's about the efficiency at which this happens. Things go "viral" in a way they never could before, just for example.

Correct.
I've cut nearly all news out of my life (1) and social media is for communicating with immediate family.
Also, I don't watch ads and if they come on the radio/tv/browser window is turned off until the ads cease.
Focus on the people near you and be in a healthy state of mind so you can help them when required.

Let x be the number of IO pins required by your project.
Let y be the number of IO pins available on your MCU.
Step 1: x = y + 1
Step 2: Upgrade the MCU or add an IO Expander
Step 3: Realize you can then add some cool functionality now you have more GPIO
Step 4: Go to step 1

I'm honestly not sure how people run out of pins, when realistically you can connect like 5 devices to an SPI or I2C bus before it collapses due to line capacitance.
I use the ESP32 for the lion's share of my projects, because it's hard to find a 512kB MCU with a dual core 240mhz processor. It's a sweet spot that allows me to perform magic, like True Type fonts with it, which makes all the difference in the world when it comes to presenting a user interface.
You don't really need all the sensors in the world to do cool stuff. You just need to lock down your scope. If you need to do more, you probably need another MCU - make another IoT device. If you're running ESP32s you can use ESP-NOW to create a wireless mesh network with up to like 20 devices on it. (Or you can use WiFi or bluetooth or BLE)

Because as a hobbyist on a budget I have to stick to easily available devices. It does not help you can put more devices on the same bus if I can't easily source the devices for a single bus type.
But yes, it looks like I have enough pins on the ESP32 - I started out assuming an ESP8266 would be more than enough, but once a SPI LCD eats a bunch of pins there isn't that much left (did not see any reasonable priced i2c transflective displays)
Add an i2c for humidity, one-wire for temperature (in a "hostile" environment, so need a longer cable run to get the MCU out of there), rotary encoder, UART for reacting to a solar installation, a few relays, and a water level sensor or two - then it adds up.

It certainly would on an ESP8266! Those are glorified bluetooth modules, more than MCUs.
