I read a lot of articles about programming and technology as a way of keeping up with the industry and expanding my knowledge. Here are some articles I read in 2024 that I recommend reading.

2024 was a busy year for me so I didn’t read as much as in previous years. But still, here’s my top articles.

Ruben’s Virtual World Project was a multiplayer top-down shooter with base-building elements that was in development for five years, from 2015 to 2020. It was a hybrid between a top-down shooter and a base-builder, allowing the player to switch between Hero and Architect modes at any time.

Whilst I started the project to learn about multiplayer networking at a low level - including latency mitigation, reliability, and prevention of cheating - it quickly turned into a project to make a game and game engine.

I made an app to rate coffee shops as an exercise to learn React Native. The app allows users to rate locations based on customisable categories. Whilst it was designed for coffee and coffee shops, it could be used to rate any kind of place. The ratings are stored locally on the device and not uploaded anywhere.

The original idea was to implement the same app in React Native, Jetpack Compose, and Flutter, but I’ve only made the React Native version so far. I’ve started the Jetpack Compose version and will hopefully have time to finish it at some point.

Firefox has been my browser of choice ever since I was first recommended it twelve years ago. It has the extensions I like and it supports the open web.

I’m currently learning React Native and Expo as an alternative to native app development. To do this, I’ve been working on an app so that I can get hands-on experience with React Native app development. This includes end-to-end UI testing, using Detox.

I was surprised that Detox doesn’t have an API to interact with permissions. The device.launchApp function does have a permissions field, but this only works on iOS and runs on app start-up - it doesn’t allow you to test the actual user flow.

In this article, I will explain how you can do end-to-end testing with Android permissions, including simulating user interaction with the Android permission request modal.

I’ve recently gotten into using TypeScript when working with web technology, for creating web apps and servers. I find that TypeScript makes JavaScript more enjoyable to use. In this article, I’ll explain my reasons why.

I read a lot of articles about programming and technology as a way of keeping up with the industry and expanding my knowledge. Here are some articles I read in 2023 that I recommend reading.

In 2022, I made a goal of writing at least twelve long-form articles on my blog each year. But why bother? In this article, I will explain the reasons why I write.

I recently switched to using Eleventy to generate my blog. As part of this process, I needed to implement word counts for each of my posts. I made my own plugin for this as I was unable to find an existing one that met my requirements - they either used regex to parse HTML or included non-text like scripts and code snippets in the count.

I recently switched to using Eleventy to generate my blog. Because Eleventy is very easy to extend, I was able to add more features to my blog - including backlinks.

After nine years of using Jekyll, I’ve switched to using Eleventy (11ty) and redesigned my blog whilst I was at it. I was finding that Jekyll was too limiting and wanted something more capable. In this article, I will talk about why I switched, how I did it, and my thoughts about Eleventy as a new user.

The collapse of Twitter last year got me thinking about closed platforms and reducing the hold that privately owned platforms have over the Internet.

I’ve been blogging for nine years now on my personal website. I like owning my own domain as it allows me to retain control and stay independent of particular services. Private platforms have a tendency to be bought out and/or ruined by commercial interests, especially now with tech growth slowing down and investors getting uneasy.

I’m making a device to water my basil plants. Whilst working on this, I encountered an issue where running the pumps whilst connected to WiFi would crash the microcontroller. After investigation, I found the cause was poor grounding and Electromagnetic Interference (EMI).

Ten years ago today, I uploaded the first version of Capture The Flag. Capture The Flag is a multiplayer game where two teams of players battle to claim the other team’s flag whilst defending their own. Capture The Flag is played in a destructible voxel environment, allowing players to build defences and place traps.

Capture The Flag started life as a persistent kingdoms game but quickly pivoted to a match-based team game. It was developed iteratively, taking into account player feedback. I hosted a server for the game for many years and a community formed around it. In 2021, I handed over the reins to CTF to very capable hands; it remains Minetest’s most popular server to this day.

This article covers the history of CTF, the lessons I learned, and the changes I made along the way.

One of the reasons I learned how to program was to make games. Games are a unique form of creative medium, combining art, interactive storytelling, and vibrant worlds. But as a software engineer, it’s easy to lose sight of my goals and get trapped by the technical details. It’s common for software engineers in game dev to roll their own engine, which I believe reduces productivity and is ultimately a distraction to making a game.

Note that I’m not just referring to making reusable or generic game engines; for this article, I consider using low-level technology like OpenGL, SFML, or SDL to make games to include the act of rolling your own game engine, even if the focus is specific. It’s more manageable, but you still end up reinventing the wheel and having to solve many of the same problems.

There are plenty of other articles about whether or not to make your own game engine. This article is personal to me; it’s an exploration of my journey in game dev, a discussion of what motivates me, and a promise for the future.

In 2020, the Minetest Discord community ran a mod-making competition with “combat” as the theme. Participants had one week to create a mod with all the code written within the time, but pre-existing art was allowed. I made a Real-Time Strategy (RTS) minigame called Conquer; it received first place.

In this article, I will discuss some of the interesting challenges that Conquer needed to solve. I believe that Conquer is a great example to learn from as it demonstrates best practices for Minetest modding; it is well-structured and unit-tested.

I love making apps. I like making stuff and it’s even better when I can interact with the stuff I make. App development feels especially real as I can hold and touch what I made. So why don’t I have many Android hobby projects? This article is a reflection on the projects I’ve worked on, the problems I have, and what I want to try in the future.

Bing has now unbanned my blog. My site is still penalised/low in the results, but at least it's appearing now. See the bottom of this article for their response.

My domain was shadow banned by Bing and DuckDuckGo last year, and I don’t know why. Since then, my root domain (rubenwardy.com) has been unbanned but my blog remains banned. The event also negatively impacted the search placement of my root domain; another site that reuploaded some of my content is appearing as the first result when searching for it.

My eventual goal with electronics is to create autonomous robots and drones; I’d like to make a quadcopter with my own flight controller that can take off, land, and follow a target. This will be quite an ambitious project, and I’m nowhere near capable enough for that yet.

Previously, I created a simple plant monitor that reported stats to an online dashboard. This allowed me to learn soldering, stripboards, and 3d printing. To work on future projects, I need to be able to produce ever more complicated circuits and mechanical designs.

After watching some Lock Picking Lawyer on YouTube, I was inspired to think about different locking mechanisms. A locking box would be a good experiment with mechanical design, and if combined with IoT, would be good for electronics too.

In this article, I will cover how I created my lock box - from the problems I had, the iterations I made, and the final design I settled on. It’s a bit of a random project, I didn’t have set goals in mind. I started by exploring different locking mechanisms, and then moved to focusing on the electronics and getting it working.

Articles are a great way to expand your knowledge as a programmer, by learning from the experiences of others. A good article is also interesting to read. Here is a collection of articles I recommend reading.
