So I realized that after I ran the script that I wasn't checking for duplicates, I dunno why that just never crossed my mind. There didn't appear to be an easy way to just remove all videos so I just kind of spot checked and removed as many dupes as I could be bothered to. It's me I'm the terrible programmer.

i knew u could do it

compilation takes longer as it spends more time reasoning about the code in order to produce faster code. afaik the only other downside to -O2 is that the code gets transformed lots more which can hurt debugging sometimes, but that's no biggie as you should just switch to -O0 when debugging. unless that stops the error from happening anymore in which case you're hosed!

i read C++ Primer a few months back and found it p good. that it's called a "primer" while being 900 pages should tell you something about C++ as a language. id read C Programming previously, and while it was somewhat useful in providing context for the constructs C++ nails to C, i don't think it helped me all that much.

anyway whatever you pick make sure it was published in 2011 or later b/c C++11 made a whole pile of improvements that you don't wanna be without. C++14 added a few more but they're comparatively minor and you can pick them up by reading Effective Modern C++.

streams, sockets, connections, threads, threadpools are all things things you still have somewhat manage or at least treat differently than other things that get GC'd for you. or arenas or pools or things that if you know about them beyond voodoo you are good

unless you are writing a trivial/bad program, in which case, sure, you don't have to ever clean up memory either

C++ Grandmaster Certification

Overview
Students of this two part online course each single-handedly develop their own original C++ compiler, standard library, and toolchain with the following features:
- Compliant with the latest 2011 standard (C++11)
- Written entirely in C++ with no third-party dependencies
- Code generator targeting Linux x86_64
- Full toolchain including preprocessor, compiler frontend/backend, assembler, linker and all standard library components
- Builds with itself (self-hosting) and passes provided conformance test suite

Isn't this a huge undertaking, usually done by an entire team of programmers?

Yes, earning the title Certified C++ Grandmaster is for most programmers the hardest programming exercise they have completed in their careers. It requires writing well over 100,000 lines of code, implementing about 2000 pages of dense technical specifications and takes over 1000 hours of intense work for that small percentage of world-class programmers that are ready to complete it at all.
