    "I once had to change a decision i had previously made when I got stakeholder feedback that seemed to contradict what was already designed or already even built - such as the way a page was architected or the designs or colors used on a page. I had a justification for all decisions made, but sometimes the stakeholder feedback brings a perspective, such as a part of the user experience, that I had not thought of before.

    "First of all, stack and heap memory are abstraction on top of the hardware by the compiler. The hardware is not aware of stack and heap memory. There is only a single piece of memory that a program has access to. The compiler creates the concepts of stack and heap memory to run the programs efficiently. Programs use stack memory to store local variables and a few important register values such as frame pointer and return address for program counter. This makes it easier for the compiler to gene"

    "As an interviewer, I have asked this question to candidates in the past. Here are the major topics I am looking for in an interview The candidate should understand that there are ways of measuring the loss of a particular clustering. For example, we can take the average distance of each point to it's cluster center. The candidate should understand that this loss will always decrease as the number of clusters increases. For that reason, we can't just pick the value of K that minimizes the l"
