Started with machine code. Went on to assembler, then C (with assembler functions, cos I could opimize better than the compiler). So I find it natural to think about what's happening at low-level.

I used to think that way about memory layouts in C/C++, but strings in the newer languages where everything wants to be on the heap make it kind of pointless.
I trust the optimizers in the compilers for the execution flow. (Unless it is a C compiler from DEC where I recommend /DEBUG to disable optimizations)

I will assume they are all hunt and peck when it comes to the keyboard!
If you can't laugh at yourself - ask me and I will do it for you.

... And I can't tell if it's a regular expression or he just walked over the keyboard ...

Back in the day when I used Wordstar to write all of our user manuals I had been really stuck into some heavy duty writing and had forgotten to save my work for some time ...
To close down Wordstar without saving any of your work required the rather complicated keystroke sequence of Ctrl+KQY.
Any other sequence would result in nothing happening or at worst an error message.
Any. Other. Sequence. Of. Keystrokes.
Enter my cat (kitten) ... took a stroll over the keyboard... Hesitated when I screamed, with its paw hovering over the Y. Looked me right in the eye and placed that paw down. Evil incarnate, I swear.

Back in the day when I was using Wordstar I was using it on Z80 Superbrains.
The reset for a Superbrain was to press the red keys at each end of the keyboard simultaneously. Something that YOU WOULD NEVER DO accidentally.
In comes my two year old daughter.
"Ooh look two red buttons", pressed simultaneously by index fingers of two hands.
BANG!!
All work gone!
Ah well. (I'm sure that those were the days!)

OMG - Superbrains ... me too! Those were days, not sure about the "the"
Did myself an injury trying to carry one of those into the warehouse - slipped on a step and landed sternum-first on the keyboard edge. The SB survived unscathed (well, we finally found the T key at the other end of the warehouse), but two of my ribs were broken!

Reminds me of a joke from many years ago about the TECO text editor[^] on DEC equipment. You could enter your full name and it would be a valid set of commands. It was interesting to see what actually happened.

This was well known in my student days (early 1980s): People with names that actually did something useful when typed in Teco enjoyed a certain reputation and fame.

Not really. He's more of a tester, but he does work his paws to the bone. It's a good thing the work isn't too ruff. He's shed all of his other dooties.

We have a couple of rescue GH's that come down to the beach, when they start to run the labs just stand there in awe, it is a wonderful sight to see them run just for fun!

It is indeed. Zoomies, even in a small yard like mine, are amazing!

I show him a few weeks ago a new-retro game on C64, and he got exited, first to play than to change (adding things that C64 cannot probably do  )
So we agreed I will teach him... So we started on how actually all that magic works on the lowest level (ones and zeros)...
After a few explanations he even more excited to learn...

Wow ...  this is interesting how programming constructs are mapped visually in Scratch ...
I did not pay attention to visual programming, and at first sight it looks like well-done

I wrote a backgammon board in Scratch. I started trying to make a 1 player vs computer.
In order to work on the computer algorithm, I tried to create it first in C# using the crudest array operations that would be translatable to Scratch. I was pretty happy with the algorithm, but I never went back and included it into Scratch. It would have been a real bear to translate.
The old Scratch was written in Squeak/SmallTalk which was another reason I was interested. The whole Scratch environment was implemented very elegantly and a great reference code. Then it was in Java(?) for a while and now it could be JavaScript?
I really liked the simplicity of the Boolean operators in Smalltalk. A great lesson in minimal OO design.

Thanks, good to know ... I will check more info about Scratch concepts and implementations

She's had some exposure to (very wrong) Visual Basic.NET WinForms and SQL Server in the past and even wrote some of it.
The kind that does On Error Resume Next, Go To, had lots of empty Catch-blocks (in the deepest nested functions, so you'd never know when something failed), had 5000-line WinForms with no separation of concerns or code re-use whatsoever... You get the idea.
Luckily, that's a long time ago and she forgot most of it 
I told her to start with the basics of C# so she can learn the syntax and the framework.
She's now following some online course, which teaches her to add integers, do string manipulation, etc.
I don't have the link, but I've seen it and it's pretty nice, with assignments that she needs to finish, and even some tips on how to use Visual Studio.
She's making good progress.
She wants to work with databases, learn about ASP.NET Razor Pages and create a web application.
Any tips on where to go next?
Online tutorials and books would be great, she needs things explained in an orderly manner.

To make things a bit easier she might also be interested in a .NET web app code generator like Magic.
