Pre-commit hook is automation. It formats the code and gives you linting notes the moment you write "git commit".

It's not more mental bandwidth for me. Because I write the new, and directly delete at the point I need to, then I never think about it again. If I botch something, valgrind will tell me, even pinpointing it with line number.

If that works for you, use it. I have no objections.

Because not everyone has the same values, not everyone has an engineering background even though they like to call themselves engineers, most programming projects are delivered by external companies that don't care about quality unless it is required by law (aka liabilities).

Any ideas where to start learning C++ as an embedded developer? I wrote many lines of bare metal C code and want to transit to higher level jobs. I see many expensive or completely free courses, but I am not sure which one is usable in my complicated situation.

There is no modern C++ without the old C++. C++ is the success that it is exactly because it has been able to evolve with no shameful past to cancel.

We don't talk about auto_ptr.

`union` is all I need to mark my territory and make sure no one touches my property!

So isn't that a tool that enforces something upon the programmer?

What is the benefit of needing valgrind? Isn't it even better to have the task automated away so that the problem doesn't even come up?

So use RAII and smart pointers. I think that's the point.

Yes, exactly what I'm saying. Use tooling to do the boring parts of your job.

It's a tool I voluntarily add to my workflow, which works the way I want, when I want, according to project needs. It's not a limitation put upon me by the language/compiler/whatnot.

> What is the benefit of needing valgrind? Isn't it even better to have the task automated away so that the problem doesn't even come up?

In most cases, performance (think of HPC levels of performance). If I don't need that kind of performance, I can just use the stack or smart pointers.

If we're talking about moving to other programming languages, I'd rather not.
