1. The lounge is for the CodeProject community to discuss things of interest to the community, and as a place for the whole community to participate. It is, first and foremost, a respectful meeting and discussion area for those wishing to discuss the life of a Software developer.
The #1 rule is: Be respectful of others, of the site, and of the community as a whole.
2. Technical discussions are welcome, but if you need specific programming question answered please use Quick Answers[^], or to discussion your programming problem in depth use the programming forums[^]. We encourage technical discussion, but this is a general discussion forum, not a programming Q&A forum. Posts will be moved or deleted if they fit better elsewhere.
3. No sys-admin, networking, "how do I setup XYZ" questions. For those use the SysAdmin[^] or Hardware and Devices[^] forums.
4. No politics (including enviro-politics[^]), no sex, no religion. This is a community for software development. There are plenty of other sites that are far more appropriate for these discussions.
5. Nothing Not Safe For Work, nothing you would not want your wife/husband, your girlfriend/boyfriend, your mother or your kid sister seeing on your screen.
6. Any personal attacks, any spam, any advertising, any trolling, or any abuse of the rules will result in your account being removed.
7. Not everyone's first language is English. Be understanding.
Please respect the community and respect each other. We are of many cultures so remember that. Don't assume others understand you are joking, don't belittle anyone for taking offense or being thin skinned.
We are a community for software developers. Leave the egos at the door.
cheers,

One of the things that really helps me when coding in C++ with templates is I can easily visualize the result of the template expansion/instantiation as raw C++ (no templates)
When I'm coding in C++ I can visualize the equivalent C as I'm coding.
I can also to a degree, visualize the assembly. Not in any specific sense, but in a sort of pseudo-code like "I know when we're doing a shift, an add, and a push here" kind of thing.
I do this to a lesser degree in C# even, when I'm considering performance. I think about C++ code required to get it to do the same thing - but like I said to a lesser degree.
Do you do this? I'm just curious. It feels like such a blessing sometimes.
To err is human. Fortune favors the monsters.

I have a good sense of what's happening underneath and will think about it if it seems important.
I never coded in C but spent a lot of time in a proprietary, procedural language that might be described as a cross between Modula and a stripped down Ada. We sometimes implemented polymorphism, inheritance, and encapsulation manually, so how OO languages did it wasn't a surprise.
Having to parse and instantiate the code for templates significantly improved my understanding of what was going on there.
My most recent experience actually writing assembler was on the PDP-10 π², but what happens in the depths hasn't changed much. Once in a while, I'd like to step into x64 assembler to see what the O/S is doing, but I can't follow it very well. Maybe someday it'll be important enough that I get my butt in gear and dig into it.

I call it the x-ray vision. I look at some code and visualize the code approximately how it will be when it runs.
Common? Probably not. I came to C and C# etc from an assembly background, but most programmers nowadays do not. Hence why they're happy to use constructs that are "nice on the surface but gross underneath".

I don't use a "UI designer" in WPF or UWP; it's all XAML and / or code for my UI. I can visualize the whole visual tree.
I can't do the same in Windows Forms; you "need" the UI designer (IMO).

In a sense, any developer "worth their salt" can model what the machine is doing in their head. The merit of their code will reflect their ability to do just that. I don't think the approach you take to the model matters all that much. All that matters is the fidelity of the model to the task at hand.
I've worked with a couple 'cargo cult' programmers who genuinely couldn't do this. All they did was recognize a pattern to the task and copy/pasted code they'd seen that matched the pattern. They would then bash the code with a hammer until it more-or-less did what was required. It's hard working with them, because they don't understand what's wrong with what they did.

Any decent programmer should have a good idea of what the VM (the one we program to, not the physical device) is doing. A good programmer will be able to see how this affects the processor (what CPU instructions are being executed). An outstanding programmer will take this one further level - how is this affecting the system (memory usage, caching, disk swapping, etc.).

(I may have posted this before, if so, apologies)
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.

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.

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.

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...

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.
