I chose Rust as the language for the Botters of the Galaxy contest. My code structure was suitable enough to get me to the final league, but I had a few […]
Dissecting my Rusty Superhero Bots — The code review
UI Layout: Natural versus dependent size
Elements have either a natural size, a dependent size, or combination of the two. The size of an element influences its placement. The user and creator of a UI layout system must […]
Drawing a bitmap in the window (Leaf-SDL #2)
Read Update #1 Syntax Error I addressed two problems since last update: A bad error message, and an image loading error. The bad error message was triggered when an unknown symbol […]
Fixing some vector drawing issues
I fixed several issues with the vector drawing in Fuse. A few of them seemed somewhat obvious, so as with all such issues, I wonder why they were even there. In this […]
New Game: A quest for graphics (Leaf-SDL #1)
I’ve started a journey to make Leaf more visual. You may have seen some of my videos about complexity, complete with shaky mouse drawn lines. It’s simply not good enough, especially […]
Innocent growth of technical debt
I’ve spent the last several days unravelling the mystery of the Each feature in Fuse. It’s a powerhouse feature that has managed to accumulate a fair share of technical debt. Though in […]
Debugging a defect with a shared argument
While writing some error handling helpers, during my algorithm stream, I encountered a defect. It’s a tricky one dealing with the passing of shared arguments to functions in Leaf. After a lot […]
Should function arguments be reassignable or mutable?
Working on a defect in Leaf I had a question: should function arguments be reassignable within a function? Are they just like local variables, or should they be treated specially? It would […]
Are global variables bad?
We hear it often, “global variables are bad, avoid using them!” But is this actually good advice? Simplified blanket statements are already a bit suspicious, but if we get into the details […]
What is a closure?
You’ve heard the term, you’ve probably even used them, but what exactly is a closure? It’s a combination of data and code that have become a staple of modern programming. They offer […]
Adding += and friends to Leaf
Yesterday I finished a rather simple Kata from Codewars: the sum of a sequence of numbers. It was straight forward to implement, but I felt like it was missing something. It looked […]
What is reactive and stream programming?
Reactive programming is a paradigm that creates permanent relationships between values. Rather than one-time calculations, a reactive expression updates its result whenever the source value changes. Perhaps first popularized in spreadsheets, and […]
Debugging a synchronous callback in loop defect
A bug snuck by me while adding a new feature to Each: a behaviour in Fuse that dynamically adds UI elements. I had to change a lot of the code, so I […]
What is declarative programming?
Declarative programming is a paradigm that expresses the desired result, not how to achieve it. It uses rules and constraints to describe a user interface, the layout of a network, the structure […]
