I'm sure many will disagree, but bitwise operators and operations should be common knowledge for programmers. Why? Because it is linked to understanding how data is stored and manipulated by computers. Computer scientists and Engineers generally understand these operators, hackers and "coders" do not. With this opinion, the title does not match the content.

Is this not already common knowledge? It's taught pretty extensively in one of the required lower div CS classes at my university, and it's usually in other schools' curriculums from what I've seen.

Somewhere around half of the candidates I interview have a tough time with hexadecimal, and definitely can't do bit manipulation without help.

It's kind of depressing, but I've adjusted how I ask my problem since it's not actually needed to demonstrate the skills I want to see. It doesn't take long to learn bit manipulation when it's needed, even though it seems like a foundation of computing to me.

So is calculus, yet apparently most CS students can't really integrate shit by the time they get to graduation...

Learned to integrate in High School, never used it again for years. Used in like 1 out of 5 Math classes at the start university. Haven't needed it for a good.. 13 years I guess?

Indistinguishable from "can't really integrate shit" without some hours of relearning.

There are a lot of computer programmers who never went to school.
