That's my "cookbook".

My wife and I have been experimenting with slow-cooker recipes of late. It's handy, especially with young kids, to not be tied up with a lot of post cooking cleanup. Coming home to a house filled with the smell of food is a nice mood enhancer, too.

Look for clues on whether it's meant to be THE meal for thanksgiving, or one of the dishes in a french nine dish dinner.

I always, deliberately, cook more than needed. What isn't eaten goes in the fridge/freezer. If I'm going to spend, (a fairly unenjoyable), time prepping and cleaning up the sizeable mess that I always manage to create, I want the maximum benefit. And a couple of cooking free days, sort of makes it worth it.
Being a veggie, pretty much everything is good for freezing - and, somehow, it tastes better when all you've had to do is defrost and stick it in the microwave.

I'm trying to come with a simple article on building state machines. I figured it wouldn't be too complicated, nor should it be since I wanted the article to be accessible to beginners.
The trouble is, I can't think of a simple example of a state machine that is real world at all, and I don't want to lead with something contrived because I also want to explain the "why" of state machines with a practical example.
This shouldn't be very complicated. I've been writing state machines for various things since the mid 1980s. In all that time I must have done something simple, especially since I was coding on a 16-bit machine back in the beginning.
Grrrr

What about? 
Start State - BigRedButton1_Pressed ---- coffee read ---- Got to Start Again
\
---- BigRedButton2_Pressed ---- Nuclear War --- End State

I've really done it. Ever since I wrote my GLR parser generator, which can create parsers that even parse human language I have run out of things to code. I jumped the shark.
Now I've been slumming it writing small tips instead of whole articles.

I am having a slum in my motivation too... since I got stopped on my UI math problem... (like.. 3 years ago?)
Although.. I started my app recently and got a few new ideas! 
But then, I started playing Assassin's Creed: Odyssey again! ^_^
I think the key here is, are there anything you want to learn?
That's what usually start the creative juice again! 
Like even now, every now and then, there is a new tech that popup at work that make do some more homework. Like Blazor, Blazor is cool. Though I am holding off for the official WebAssembly release now!

Yeah I thought about learning Blazor but I have little reason to do web dev anymore, except maybe writing blazor components for other people to use.
Still, WebAssembly seems iffy to me to use for a production website, if only because I can't imagine the load times on a large blazor app given how WebAssembly works. Then again, if it's all demand loaded maybe it's not so bad, but I don't see how they can demand load parts of System.dll (or equiv) for example.
Then again, I've never used it - only read about it and have a fair understanding of the general principle, being a more refined, evolved version of web based virtual machines compared to asm.js (which I'm familiar with)

Have a look....
This is NOT Blazor, but it's a Ginormous WebAssembly demo...
https://windowstoolkit-wasm.platform.uno/
My first page load is... indeed taking sometime.. 
Although.. For Blazor WebAssembly they do a lot of work on trimming down everything...
And the runtime will be cached using HTML5 file access for longer persistance..
And app themselves are usually pretty small...
I guess we shall see soon, the release ETA is sometimes this month!

Yeah, my point was I don't see it scaling well for large or otherwise complex apps with a big codebase.
If the US wasn't lagging behind in fiber-to-the-curb it would be more practical here because you wouldn't still have people on 3Mbps connections

Make a tool to create languages...
|
|
|
|
|
I've already created a lot of tools for building compiler front-ends. I even developed my own language (actually a subset of C#) for reasons. This however, would be too complicated for the examples I intend to present.

You said you were bored. Think greater! A program for generating any language!  An 'inverse-parser' if you will! It could spit out anything, and each syntax could take experts hundreds of years to decipher (or you could make that your next project!)

I'll assume you mean finite state machines...

They're all contrived.
I dunno, but now you have me wondering how close to a finite state machine my JSON reader is.
|
|
|
|

Heh @ implementing non-finite state machines inside an LBA finite state machine AKA a computer.
I don't know if they're all contrived. I bet your JSON reader uses a state machine if it chunks (rather than reading the entire JSON stream at once) - mine is - I wrote one too because I wanted something fast for bulk processing.

Most of the FSMs I've written were for low level communications protocols (think HDLC/X.25, SDLC/SNA). Never did implement the new-fangled TCP/IP.
One interesting side-effect of implementing some of the older ones (Bisync flavours, anyone?) was proving that the protocols as documented were incomplete. They needed a catch-all state "Human intervention required".
Maybe a toy poll/response protocol? Two interacting FSMs, one for master, one for slave.

That's an interesting idea. I'll consider it. It also made me think of another idea involving an asynchronous implementation of an HTTP request/response cycle.

There are quite a few real-world examples if you think in overview what a FSM requires:
1) Inputs that brought the machine to this state
2) The current state of the machine and the outputs that arriving there generated
3) The new state the machine will have as a response to new inputs
So: navigating a vehicle on an small island could be modeled as an FSM. A drinks vending machine. Traffic lights (sooooo simple, very small set of states). Voting systems (could get humorous).
Good luck!

As Griff already suggested, a vending machine would probably fit the bill.

There was a QA a while ago about 'decoding' some data - the eventual solution was proposed using a RegEx - I was in two minds about it, I personally would have used a state-machine, or maybe it was a 'borderline case' (as opposed to me, 'nut case')

Do you own a car ? Think about any car part that is based on electronics or electrical actors -> It runs a state machine. Embedded is full of state machines. Actually, state machines are the AI of embedded world.

An example that could grow into something non-trivial, but that everyone understands, is a set of four traffic lights.
|
|

If you can't think of a real world example then maybe it's not something people particularly need to know about?
|
|
|
|

When I hear "state machine" I think of games.
Maybe you could write something about that?
Also, don't know if I used it right, but I once used a state machine for order processing.
The order could go from "ordered" to "paid" and "paid" to shipped, but never "ordered" to "shipped", or something like that.
It was a bit more complicated than that, but it's been a while so I don't remember, but it was something like that.
