I'll admit I have a lot of reading to catch up with to reach the level of understanding about networks that I'd like to have. Well, specifically, subnetting.
After some going back and forth with ChatGPT for about half an hour (trying to get it to rephrase its answers to try to show it that previous answers were clearly wrong), I've only managed to become less certain about many things, but I'm hoping I've at least come to one correct conclusion:
I want the valid IP range on my home network to be restricted to 192.168.X.Y, where X ranges from 1 through 31, and Y ranges from 1 through 254 (with the understanding that, for all intents and purposes, you never directly assign [whatever].0 or [whatever].255 to a device).
So, the subnet I should be using is 255.255.224.0 (so for the third octet I could use everything between 1 through 31).
What I haven't been able to get out of ChatGPT is whether a machine configured with an IP between 192.168.32.1 and 192.168.255.254 would fail to reach the rest of the systems on 192.168.[1-31].[1-254]. It sounds right to me, but until I try, I'm just guessing.
Generally, I configure all of my systems with a static IPv4 address. And I want all systems within my network to be able to see each other, just to keep things simple.
Am I right at least so far, with that subnet of 255.255.224.0?
Further discussion:
The idea is - for the third octet - the 255 devices under "1" would be my physical machines. My laptops would be under "2". Printers under "3". My first VM host would be at 10 (192.168.10.1). VMs it hosts would be 192.168.10.2 through .254. My second VM host would be 192.168.11.1; its VMs would range from 192.168.11.2 through 254, etc.
Of course that leaves some big gaps within each range, but it does keep things organized (at least in my mind it does). I'm no network admin; do people segregate things this way?

Not dissing Chris, but the stupidity of Microsoft never ceases to enrage and mystify me. Most companies are started from enraged employees/customers that know they can do it better, and they do... anyway...
So, let's talk Windows 11 and the bs that MS blows our way for UI improvements. Rounded icons, ads in the startup bar, ever invasive AI, yada yada. Well I work on a laptop 99% of the time. I'm not that mobile, I just like the size. I have Windows 10 and 11 on multiple machines. Today all I wanted to do on my Windows 11 laptop was to turn off the touchpad when a mouse was connected. It's a fairly common thing users want to do.
So, where do I find it? The setting is hidden under a drop down bar where you just have to be intuitive/desperate enough to keep clicking. Help is useless, and most of the doc on Windows 11 trails the ui... what a steaming pile of debris.

Windows 11 needs a massive, massive cleanout. The full Marie Kondo treatment.
The update UI that wraps the older UI that wraps the win 10 UI which wraps the Win7 UI which wraps the Win95 has, I feel, reached the tipping point of collapse. Just right click on the desktop and then select "Show more options" as Exhibit A that the UX Product Manager just gave up. Removing quick tasks from the contect menu of taskbar icons was their way of saying "I hate the World".

I've been using Windows 10 on an iMac for years with a secondary monitor. This year I've switched to macOS as my main dev system on the iMac, and the other screen is used for my win11, Ubuntu, Debian or mac mini machine. Lots of juggling.
I'm working on the iMac on one file, and on the mac mini on the same file, but a different version. I was wishing I could just copy from one to the other, but they are on different machines. Then, without thinking, I copied some text, dragged the cursor from one screen to the other, and then pasted.
I totally forgot about macOS Universal control. It was so intuitive I wasn't even aware of what I was doing: it just worked the way I expected it to (but had I thought about it, I would have not expected it to work).
I love UI/UX like that. It's like the perfect butler: they are there before you even realise you need them, and then step back once the job is done. But without the whole moral issues thing and all that.
I wish we all had the time and resources and mental space to write software that worked like this.

It's been my experience that companies will spend hundreds of thousands so people can argue over a text box for months and call that innovation.

It came with the Logitech mouse drivers, maybe four or five years ago. I never worked with "i" stuff, but if I remember the documentation right, it worked across OSes.
I never saw a standard protocol for cut & paste across internet - maybe it exists, maybe it even existed then. Most likely, Logitech devised its proprietary cut & paste protocol between its drivers. They are just talking to themselves, need not relate to other mice or OSes (except that the mouse driver will have to know how to do both copy and paste on the local system - but if you write a driver for an OS, you are likely to know that!), so there really isn't that much need for a world standard protocol.

Sort of like Synergy? Synergy - Share one mouse & keyboard across computers Although that's sort of the other way around, perhaps being best described as a software KVM switch, that allowed you to cut & paste between systems. Maybe drag-and-drop, too. It's been a long time since I used it, but your description of rang a bell for me. So, if you're looking for something to do this, and you have windows/mac/linux systems, it might be a solution for you.

I would love to have something like this, Microsoft supports this, but you have to login to the Microsoft ID. I refuse to do so. i have an app in the works...

I'd never heard of it, but according to the sparse information I can find it's a sort private e-mail network that predates e-mail.
Apparently it's "popular" for EDI exchange and not much else (although the military and NATO use it, among others, because it's more secure than e-mail).
I just got a question from a client if I can deliver an EDI message via ATLAS400 instead of regular e-mail.
Seriously, as soon as someone mentions EDI I get shivers down my spine.
How can something be so ridiculously obscure and complicated and yet so popular!? 
A simple OpenAPI specification would've done the trick! (I know, EDI predates REST, JSON, SOAP and even XML...)
Anyway, it seems I need some subscription to an X.400 service and even then, there are 0 code examples on the entire internet...
So much for "industry standard"

Oh man now I feel old. I think we used that on AIX machines in the early 90's.
Good luck! You've got this!

It rings a bell. Maybe bank networks, like ATM machines use it? IDK. I just think it sounds familiar.
NVM, I'm thinking of something else.

X.4nn are ISO standards that describe mail systems at various levels. I assume ATLAS 400 is a product/service that supports X.400 messaging and then the question becomes how do you interface with it.
Back in the day the X.400 systems I worked with (ISOCOR, Exchange) had file gateways, you simply prepared a valid X.400 binary object and that was picked up by the mail server. ATLAS 400 may have other options, their website is in French so I can't tell.
If you need to generate X.400 objects then you'll see the standard is complicated, like all international standards, but since you're presumably only sending, and fairly simple e-mails at that, you only need to cover a limited subset. If you can't find any libraries that you can use I may be able to dig up some old code (25 years+, plain C) that might be of help. Writing it from scratch isn't terrible if you're used to reading standards, BNF etc.
I assume the EDI part is a solved problem. You probably don't want to write your own code for that.

Well, that's a little disturbing. A human driver would not stop for a person wearing a "STOP" T-Shirt. Imagine what might happen if a self driving vehicle encountered a person wearing a "Speed Limit 100" T-Shirt! Clearly the Traffic sign detection algorithms need improving.

Brings up a serious question.
What about flagman/person who are controlling the traffic flow when a construction crew is occupying one lane of a two lane road. They often have hand held stop signs, but it is not a stop and go situation. You have to wait for the flagman to flip the sign around to the "Slow" sign to safely cross over into the other lane of traffic to get by the work crew.
