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 […]
Drawing a bitmap in the window (Leaf-SDL #2)
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 […]
Interview Question: A two-player card game
I’ve been asking interviewees, over at interviewing.io, to write a simulation of a two-player card game. It’s an engaging question, revealing a lot about their abilities. It doesn’t involve any trickery nor […]
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 […]
Hidden complexity in cute animal pictures
You head over to your favourite link site and click one of the pictures — or let’s be honest, you ctrl+click all the pictures. Your browser is filled with tabs of cute […]
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 […]
Why I’m not a fan of pair programming
Pair programming feels like a lingering ghost. Its adherents proclaim it to be the best approach to coding while the rest of us just continue to ignore it. I’ve only tried it […]
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 […]
