Data structure is one of the most fundamental theory that I think as a software engineer, we need to be exposed to as many as possible. Different implementation of lists also matters, for example, linked lists versus array lists and things like that. Just by implementing a correct data structure, you could gain a lot of time efficiency just by changing the implementation. So moving on to the second quality, which is about memory of space usage. This is also probably something less emphasized probably than speed. But I think it's also important because these days computer is so cheap.
“Seriously good software is not just software that works. It is not just software that satisfies its functional requirements, so it does the right thing, but it also does it in the right way."
Marco Faella is an associate professor at the University of Naples Federico II and the author of “Seriously Good Software”. In this episode, Marco explained what he means by seriously good software, looking at software quality from multiple different perspectives. We then dived deep into several of those software qualities with some practical tips on how software engineers can improve their craft to produce high-quality software. Towards the end, we also touched on the concept of minimum viable code, why it is important to have an idea of what the ideal code looks like, while still being practical in finding the right compromise.
