Join Simon Allardice for an in-depth discussion in this video Areas of efficiency, part of Foundations of Programming: Code Efficiency.
So I'm using the term code efficiency for the title of this…course but there are other terms I could have used like program optimization.…Now, some people might think of these concepts with words like…performance or just speed but those don't tell the whole story.…And in truth none of these terms are really good.…One of the challenges discussing this is the words we…use like efficiency or optimization, they sound very clear, very…precise.…Afterall if we can be efficient then surely…our program is either efficient or it is inefficient.…
Our code is either optimized or it is not, simple yes or no.…The reality is much more complicated, because as already mentioned, we…can work on the efficiency of multiple areas of our application.…And what we improve in one part of our code could be detrimental to another.…Now, for the purposes of this course, I'm going to explore…four main areas we can work on efficiently, four areas of focus.…All of which I will go into as separate sections…of the course, but let me introduce them here first.…
Learn to choose the right data types, understand the pitfalls of using high-level languages, and decide where to spend your time. Plus, see how the underlying memory management model may have more of an impact than you realize, and what performance issues you can expect working with databases and web services.
