I needed a way to embed a text file in my C++ code. I recently introduced Leaf code into the Leaf compiler and didn’t want to depend on a file dependency at […]
Embedding a text file in C++ code (with Scons)
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 […]
Do we need 3, or just 2 error types?
Error handling is hard, and it’s made harder by a rich error hierarchy. Programs that successfully handle errors tend to have only a couple of generic handlers. Code that catches specific types […]
Writing software for a malicious world
How do we write software that survives in a world of malware? Is it just a matter of writing safer code or do some of our core assumptions need to be modified? […]
What is functional programming?
Three key concepts comprise the essence of functional programming: first-class functions, pure functions, and immutable data. Together they express a fundamental architectural paradigm on how units of code interact with each other. […]
Improve quality and lower costs with assisted manual testing
Testing graphical user interfaces is a challenge. Full automation is appealing but it’s expensive and doesn’t yield good results. UI’s are something where a real human should be involved. By using an […]
Microsoft is absolutely at fault for WannaCry
Microsoft has played a significant role in the damage of the WannaCry ransomware. Certainly the proximate cause lies with the malware’s authors, and they should be held accountable. The complacent NSA is […]
Sorting a file: A real program in Leaf
Finally, a big step for Leaf: something that could be called an actual program. Over the weekend I finished a program that loads a file, sorts the lines, and writes it to […]
What is imperative programming?
Imperative programming is a paradigm that explicitly tells the computer what to do and how to do it. Unlike most other approaches it is a relatively concrete view on data and execution […]
Yummy UI food with keyframe animations
When I saw the below demo I thought “neat, how’d they do that”? That may sound surprising if you knew that I wrote the API for this. In this article I’ll describe […]
Bravely squash or cowardly refuse: a git conundrum
Why would somebody ever want to take perfectly fine code history and erase it? Phrased like that it makes git squashing seem ridiculous. Alas, some people find sanitizing history is the preferred […]
Working with types and named constructors in Leaf
As types are a keystone in Leaf, working with them must be fluid and simple. I recently improved this area by adding named constructors and bare type names. The results are interesting. […]
Calculating pleasant stepping values for a chart
I needed pleasant range values for the charting API in Fuse. These are the values written by the ticks on the plot, typically on the Y-axis. In the interest of simplicity it […]
