If I release a video and send an email newsletter at the same time, which one caused the traffic increase? Should I invest in making more videos of sending more emails?
If you insist on knowing, include a different url in both that goes to the same place and use your damn server logs. You don’t need google analytics and whatever.
presumably you control the urls you are sending in the email. As a result if you want to use query strings that's fine. The issue only arises when you use query strings to implement tracking on someone else's site instead.
Interesting that the new laptop is selling beyond their expectation, and that the Ubuntu version is outselling the Windows one. Maybe their customer base is a "niche", but it seems to be one that makes them good coin nevertheless.
C++ comes with baggage and requires up-front training. You need to dive into every language feature and STL library, learn how compilers implement stuff, then decide what to use and what not to, and the decision often depends on context. It has a high cognitive load in my opinion for that reason. But once you do that, you get a relatively high-level language that can go as low and be as fast as C.
I'd say it's being able to structure your data however suits your problem and your hardware, then being able to look at a profile and being able to map read/writes back to source. Both C and C++ excel at this.
The advantage of C++ over C is that, with care, you can write zero-cost abstractions over whatever mess your data ends up as, and make the API still look intuitive. C isn't as good here.
According to my experience, all the "zero-cost abstractions" from C++ most of the time make it more annoying to maintain and/or understand the code, especially with respect to resource management, introduce compatibility issues at the toolchain level, and - even when looking perfect in toy benchmarks - are often not even zero-cost (e.g. all the bloat the templates generate often hurts).
