Software Engineering isn't rocket science ... it's harder

"UNIX is basically a simple operating system, but you have to be a genius to understand the simplicity." - Dennis Ritchie

Given an array nums containing n distinct numbers in the range [0, n], return the only number in the range that is missing from the array. int f(const vector<int>& nums) { int res = nums.size(); for(int i = 0; i < nums.size(); ++i) res ^= (i ^ nums[i]); return res; }

5 Benefits of building a deployment pipeline - Greater visibility of the deployment process - What changes have broken the app - Releases to prod have passed all steps in the pipeline - How long does it take to release - How long each step takes In summary -> Visibility

There are no easy answers. With experience, yo realize that most questions should be answered: "It depends"

Good programmer != good mentor. YMMV.

Check for if (-1 == x) instead of if (x == -1) to avoid bugs like if(x = -1)

People just want to see tasks done. Don't bore them with the low-level details. Use higher levels of abstraction in your conversation with them. And move things forward.

By no means will you be an expert after finishing a tutorial. The only way to really learn is by practicing. You are going to learn infinitely more by doing than by reading or watching.

It is often easier to not do something dumb than it is to do something smart

It's never been easier to learn to code, with so many resources available to learn from.

Is your program stuck in an infinite loop or just taking long? This is called the halting problem. Alan Turing proved that a general algorithm to solve the halting problem for *all possible program-input pairs* cannot exist.

Difference between mutex and semaphore - Mutexes only provide mutual exclusion (only 1 thread access the critical section) - Semaphores are signaling mechanisms (for example, to signal that something is complete) Binary semaphores can be used as mutexes (but not viceversa)

- "It works on my machine" + "Let's ship your machine!"

One-liner to copy a string in C: while ((*s++ = *t++) != '\0');

Problems that start with: "find" - The first n elements that - All ways to - In how many ways - The n-th - The most optimal way - The minimum/maximum/shortest path Are potential candidates for a dynamic programming solution

Procedural programming is a programming paradigm, based on the concept of the procedure calls: a type of routine that contains a series of steps to be carried out Some procedural programming languages include Fortran, ALGOL, COBOL, BASIC, Pascal, C and Java
