tough n high-leverage c++topics#IV QQ

I used to feel I have so much learning(absorption) capacity, but now I feel in my finite career I can’t really master and remember all the tough c++ topics.

Practical solution — Classify each difficult c++topic into one of

  1. QQ: high impact on QnA interview, probably the only type of high-leverage tough topic. Largely textbook knowledge. As such I’m basically confident I can learn all the basics on my own (perhaps slower than Venkat), provided I know the topics.
    1. including “coding questions” designed really for knowledge test, rather than algorithm thinking
    2. eg: HFT, Venkat…
  2. high impact on algo coding IV? No such topic. These coding IV are not about knowledge in tough topics!
  3. ZZ: high impact on GTD zbs — inevitably Low leverage during job hunt
  4. 00: no high impact on anything

Q: Is there a tough topic in both QQ and ZZ? I don’t know any.

I think 00 will be the biggest category:

  • [00] template wizardry;
  • [00] template specialization
  • [00] MI;
  • [00] operator overloading;
  • [00] pthread
  • ————-
  • [QQ]
  • [QQ] move semantics
  • [QQ] boost common lib
  • [QQ] optimization tricks. Remember MIAX and SCB IV by Dmitry
  • [QQ] singleton implementation — not really tough
  • [QQ] pimpl — not really tough
  • [QQ] op-new/malloc (interacting with ctor)
  • [QQ] memory layout
  • [QQ] specific threading constructs
  • [QQ] smart ptr details
  • [QQ] ptr as a field
  • [QQ] implement auto_ptr or ref-counting string
  • [QQ] UDP — not really tough
  • [QQ] select()
  • [QQ] multicast
  • [QQ]
  • [ZZ] IDE set-up
  • [ZZ] compiler/linker/makefile details
  • [ZZ] debuggers
  • [ZZ] crash analysis, like segmentation fault
