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.

I would associate "mon" with a Jamaican accent, but it fit.

Well,
That took me a long time to solve. I've never seen the word before. Did you set this one yourself? It's constructed a bit different than your usual puzzles.
Do you have one of these in your home? I found a very beautiful piece at Christie's[^] dated at 1746-84 that sold for quite a bit of money. I looked at alot of them online but I think this one is my favorite[^].

Yes, it's been sitting in my list since February when I last used MON for SCOTSMAN

As some of you might have been aware by some Australian post... Australian election are coming this Saturday!
On Facebook, not as private message but on a wall, someone shared an handy guide to all the minor parties. I commented, and I quote from memory, the post has been removed "party X is a bunch of crooks, shoot them on sight".
Now I was not really recommending to go full American and do a public shooting for real. It was more like a metaphor between like minded small group of friend, to emphasize how untrustworthy were those wanna be minister. Plus we don't have a tradition of public shooting here, I mean we did but no longer, thanks John Howard (even if you're a crook in other aspect).
At any rate, The Algorithm told me that my post was inflammatory and has been removed, and I could appeal if I think I was misunderstood.
I didn't, annoying but no big deals. In the past I noticed many web site have some heavy handed, wild blanketed rude language filter and they are just gonna ignore my complaint. Plus hey, I did use the words "shoot people". I mean obviously nobody I know (and nobody that would read that post) will think I was really advocating it, but, emm.. The Algorithm will think I mean my word. The Algorithm being as subtle as a 3 years old. Perhaps for good reason, according to the rumor I hear on the internet.
But I thought about it again today... it was just one click away, should have I complained, what says you?

I'd say there are a lot of loonies out there, and posting "let's assassinate politicians (or would-be politicos)" is bound to upset a lot of filters because it could be pointed at if just one loony does go postal. Even if said loonies never see it, and said politicos are crooks who do deserve a quick and merciful death - I have no idea what the parties are in Oz, let alone which one you think are crooked. All of them seem to be, worldwide anyway ...
Should you complain? No, it's probably saved you from some of the attention such things get from security forces, even if they give it a quick glance in context and decide it's nothing to worry about the fact of their looking at you and your comment history raises your profile next time you get red flagged.
Just like here: posting something obnoxious or spammy gets attention, which even if it is let through remains in the gestalt memory next time you come up. Too many memory joggers and teh ban hammer gets twitchy.

I have the have the, perhaps naively idealistic view, that one might occasionally find honest politicians in the small fringe parties!

I don't think that level of naivety lasts much past the point at which they are elected and see how big the trough they could get their snouts into, unfortunately.

Ah, the good old Daily Fail. The paper that campaigned vigorously against the "yellow peril" of Chinese immigrants. The paper which campaigned against granting women and lower-class men the right to vote, and against granting independence to India. The paper that supported the actual Nazis (right up until it became apparent they were going to lose). The paper that was a big fan of apartheid. The paper that wanted to identify and abort homosexual foetuses based on a so-called "gay gene" test. The paper that recently partnered with The People's Daily, the official newspaper of the Chinese communist party.
And that's before you get to the Fail Online's "sidebar of shame", which was infamous for perving over predominantly female - and sometimes even underage - celebrities.
But sure, we'll pay attention when they criticize the perceived behaviour of another website.
