C++ Best Practices: RAII

[@collynchristopherbrenner3245]

Sometimrs I really just want someone to show and comment on code in real time. Bravo!

[@CuriousCyclist]

Thank you for taking the time to make this video. Much appreciated.

[@NotesByNick]

Glad you enjoyed the vid! :^)

[@markusbuchholz3518]

Thanks Nick for again great video. You cover broad range of CS subjects. Perfect. Memory and CPU utilization are always the problem for RT applications. Great to have tools to approach system optimization. Thanks again for inspiration and your performance!

I like your video, you know! Hahaa I enjoyed those 'you knows' they kept me in the loop!

[@thestarinthesky_]

Great video! Thank you!

[@openroomxyz]

The example with lambda very is interesting thanks!

Bravo pour la vidéo.;)

Thanks for the video, what is the mutex library you included? I've never seen it before.

[@NotesByNick]

Under the hood it's just the pthread mutex on my machine - I'm just using std::mutex (available in C++11 and later standards) which makes this more portable (e.g., on windows it would use windows equivalent of a mutex instead of the pthread one). en.cppreference.com/w/cpp/thread/mutex

Hi! Do we have any tricks of such kind for vectors where we create the vector inside a function and return it to main function?

[@NotesByNick]

In many circumstances you will get copy elision on the return (i.e., the vector is constructed at the return address, therefore there is no copying of the vector back from the function). Does this answer your question, or did you have something else in mind?

Amazing

[@HunterNX_s]

When my program crashes in debug mode, after a memory allocation, does that allocation continue and remain as a leak or does the IDE provide a way to automatically release it? If it continues as a leak, how could I get it released?

[@RigelOrionBeta]

Memory is allocated to an application by the operating system. If an application crashes, all memory held by that application is freed by the operating system. Now that is what should happen. But operating systems can have bad logic, and fail to free memory upon application crashes. And operating systems themselves can have memory leaks. Since there is nothing lower level that an OS when it comes to memory management, that causes crashes like blue screens.

Hey Nick, Thank you for another great video. It was very concise and really easy to follow, that said, you got a new follower on GitHub ;)

[@anupkodlekere3633]

Where can j find your dotfiles?

[@NotesByNick]

What dotfiles are you referring to?

[@anupkodlekere3633]

@@NotesByNick preferably your .vimrc

[@NotesByNick]

Anup Kodlekere you can find some links to my setup info on my GitHub site here! coffeebeforearch.github.io .

You look like andre karpathy! a lot

Great video, but the amount of "you know" and "right" is too high...
