I’ve written previously about Booting Cloud Images with QEMU. However, I’ve since graduated to a more convenient method of spawning virtual machines. This method is also much faster and is more cohesive with the rest of the virtualization stack that you’ll find on your Linux distribution. As someone who creates and tears down tons of …
I’ve been having a lot of fun lately refining a weekend project I started a few months ago. I basically threw this bot over the wall back in early April. About a month ago, I started getting serious about learning the Go programming language, so I thought I’d just revisit my Discord bot with a …
Check out the changes locally For everything but the most trivial of patches, check change out locally. Not only is this a technical prerequisite for some of the other tips in this article, but I’ve found it is easier to remain focused on the review when it takes place outside of my email inbox/GitHub/Gitlab/etc. Use …

It can start to feel cumbersome after a while, especially if you bring up and tear down lots of virtual machines as part of your workflow. It’d be nice if spawning a …
Don’t you love it when your compiler thinks hard so you don’t have to? Rust’s built-in static analysis is praised for providing all kinds of safety guarantees for your code. Today, it’s not about your code, or even my code; it’s about how calling Linux ioctls through a type-safe abstraction layer exposed a bug in …
Hacktoberfest 2020 had a rocky start. I’m not here to argue against any of the criticisms brought up by other members of the community. Their feedback is not unfounded. However, I don’t believe it was all bad. I signed one of my weekend projects up for Hacktoberfest to gain some more experience in a maintainer …
A while back, I participated in a software engineering capstone with a group of other computer science students to complete my degree. Our project was to create a from-scratch implementation of grsecurity’s “randstruct” GCC plugin for the Clang compiler. Long story short, we ended up sending out a request for comments (RFC) on the initial …
