Advent of Code 2018

This year I’m taking part in the awesome Advent of Code, and because I haven’t done a lot of Ruby over the past couple of years I thought this would be an excellent opportunity to refresh my skills.¬† In case you’re unfamiliar, AoC is a series of twenty-five coding challenges. Each day leading up toContinue reading “Advent of Code 2018”

Using GCC as cross-compiler with x86_64 target

This post is a little rough, and is intended both as a memory aid for myself and as an example for anyone else who needs to know this stuff. I’ve recently decided to push toward x86_64 support in my toy/research OS project, and needed to build a GCC cross compiler for that target. In myContinue reading “Using GCC as cross-compiler with x86_64 target”

Generate less bytecode with default methods

Java’s default methods (introduced back in Java 8) are one of those features that solve the intended problem reasonably well, while at the same time allowing all kinds of nasty code and weird inheritance stuff when used in a general-purpose kind of way. Indeed, they’ve been the subject of a ton of posts and theContinue reading “Generate less bytecode with default methods”

Mocking v2.0

We all love to use mocks in our Java tests, right? Add the usual mock framework to your test dependencies, sprinkle a few mock, when and thenWhatever calls in to your code, and happy days. You’re able to test things in isolation, and as an added bonus ensure your code is actually calling the stuffContinue reading “Mocking v2.0”

Building Curb on Windows

As I mentioned in my previous post, I’m now working on Curb again, and currently on Windows. Back in 2006 when I wrote the original Curb, I wouldn’t go near a Windows box for religious reasons, and the project has never officially supported the platform. There are plenty of bugs and posts around about peopleContinue reading “Building Curb on Windows”

I’m back on the Curb team!

Way back in 2006, after reading on ruby-talk about people’s problems using libcurl with Ruby, I put together a basic C extension to replace the (by-then-unmaintained) bindings that already existed. Little did I know then that it would end up being some of the most popular open-source code I’ve written. In time, pressures of family,Continue reading “I’m back on the Curb team!”
