GCP vs AWS billing structure - Multiple billing accounts per project VS 1 billing account per aws account - Billing per project VS per sub-account - Policies at account, org, folder or project level VS org and account level

Big O complexities, from worst to best: - N! - c^N - N^c - NlogN - N - sqrt(N) - log^2(N) - logN - logN/log(log(N)) - log(log(N)) - Hyperloglog - Inverse of the Ackermann function - 1

Parameters for client-server architectures: - Blocking vs non-blocking I/o: (1 vs multiple connections per thread) - Single or batch requests - Timeouts: How much to wait? - Retries with exponential backoff & jitter - Circuit breakers: to stop operations likely to fail

Many eyes make all bugs shallow.

Distributed system: collection of independent computers that appears as one to its end users Characteristics: - They operater concurrently - They can fail independently - They do not share a global clock

I'd rather answer 1000 "silly" questions than be blocked for weeks for fear of asking

Algol (ALGOrithmic Language) was created in 1958 It has inspired the syntax of many modern language : Pascal, C, C++, Java.... Algol is considered to be amongst the most influential early programming languages

If it doesn't work, it doesn't matter how fast it doesn't work

4 Common stack interview questions 1. Polish notation calculator 2. Implement a stack using a. 1 Array and b.1 Linked list 3. Design a stack with min/max in O(1) 4. Implement a queue with 2 stacks Try to solve them (easily googable)

3 JavaScript interview questions How many ways can a function be invoked? What's the difference between a function expression and function declaration? What is event.currentTarget?

I've yet to see a UML diagram in a professional environment.
