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 […]
Fixing some vector drawing issues
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 […]
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 […]
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 […]
I’m proud to be a programmer
I’m a programmer. If you think that means I write code, you’re wrong. As a programmer, my job is translating ideas into a working computer solution. Beyond coding, this involves a myriad […]
What is event programming?
Communicating between components with events is one of the fundamental programming paradigms. One module publishes an event, and other modules respond via listeners. It’s an asynchronous model that provides an excellent separation […]
