Nearly 9 months ago I left the working world behind to embark on my PhD. I’m lucky to have this opportunity and think it’s worthwhile to log the journey. I intend on this becoming a bi-weekly (twice monthly) occurrence, where I’ll recount my progress (if there is any) and consider …
As jobs become more tech-oriented and budding software developers attempt to join the field, it’s important that they’re not ‘gate-kept’ out of the industry. Unfortunately, this can happen before a new programmer ever even writes their first line of code. There’s no shortage of reasons for why this might happen …
Vector sum: to sum up the elements of an integer vector and store the result in some destination. Following on from the previous post we’re now going to look at some rough timing measurements to compare function performance. To talk about performance we need to create some simple benchmarking code …
Vector sum: to sum up the elements of an integer vector and store the result in some destination. In this post we’re going to begin investigating how to implement the ‘Vector sum’ function defined above, in doing so we can see how attempts at performance improvement affect the functions runtime. …
Objects and Classes are terms in programming which are sometimes used interchangeably, for anyone who may be confused about their meaning the below information should be helpful. Object Oriented Programming (OOP) is a paradigm in software development for creating programs which are comprised of and utilise entities called ‘objects’. These …
Following on from my previous post here and the accompanying advice for achieving object immutability in Java, i.e Avoid public class properties. Avoid providing setters to instance fields. If a class has mutable dependencies then we must ensure we use copies of these (defensive copying). We can add another point …
Objects in Java are typically mutable, meaning that their internal state can be readily altered. This mutability can lead to a host of unwanted consequences and makes it difficult to guarantee thread-safety. To try ensure an objects immutability there are a few simple measures which can be implemented. Avoid public …
Can’t invert a binary tree? Can’t reverse a Linked list? Can’t formulate a perfect dynamic programming solution in 30 minutes with optimal time and space complexity? Well good luck getting a job, peasant… So maybe that’s an exaggeration, but the reality of programming interviews today is not too far off. …
When faced with difficult tasks or circumstances I often purposefully ponder “What if this were easy?”. A deceptively simple question but the ideas that follow can be remarkably helpful. I picked up this habit after reading Tim Ferris’s “Tribe of Mentors” several years ago. As an example let’s imagine that …
