Introduction There are a number of times when I’m working on something and need to set an API key as an environment variable.

Introduction A common problem I run into when containerizing apps is checking the files included in the image.

Introduction Recently, I was looking into converting my blog to use hugo modules and saw that hugo supports splitting the configuration file into multiple components.

KDocker 6.1 has been released!

Introduction KDocker 6 is now out and I want to take some time to reflect and think about what the future has in store for it.

Introduction It’s finally here, KDocker 6.0.

It’s been quite a while since the last KDocker release but, here we are with a new release!

Introduction A little less than a year ago I switched to hugo for my blog and I’m still liking it.

Introduction Deployment is an issue I’m having with “is it Easter”.

Introduction In the world of software, no project is ever truly complete and “is it Easter” is no exception.

Introduction Easter passed by not to long ago and I found out that Easter day is determined by the phase of the moon.

Introduction Chip-8 runs at 60 fps (frames per second) and it’s very important to maintain this frame rate.

Introduction Sound in Chip-8 is very easy.

Introduction I’ve been following game console emulation for a long time and I decided I wanted to learn more.

Introduction When I was containerizing my blog search service, I went through multiple iterations of the Dockerfile as I was learning how to create an image.

Introduction A few years ago I switched from WordPress to Jekyll and I lost full text search.

Introduction Earlier this year I looked at switching from Bitwarden (online service) to self hosting Vaultwarden.

Introduction My go to web server has always been NGINX and it’s been my default choice since I started this blog.

Introduction I needed to update some pages on my blog and while looking at it, it feels a bit stale.

Introduction A few months ago I setup a private DNS resolver with ad blocking.

Introduction For about the past 14 years I’ve been using Linode as my preferred personal VPS provider.

Introduction One of the bad things that the C language allows is setting variables and calling functions directly in an if statement.

Introduction When I switched from WordPress to Jekyll I gave up searching posts.

Introduction No app is ever complete and you’ll never get to the point where users stop asking for new features.

Introduction Currently we have a generic list container which uses void pointers to allow anything to be stored.

Introduction Lists (dynamic arrays) are yet another super useful data structure that C just doesn’t have.

Introduction We have this amazing generic hashtable and we can put pretty much anything we want into it, but it has a few flaws.

Introduction So, C doesn’t have a native hashtable object but that’s not a problem because we can use one one someone else wrote.
