Using Git Subtree for Repository Mirroring

by Paurav Hosur Param, 2 September 2025

In a recent client project, we needed to mirror a specific subdirectory from our GitLab monorepo to a GitHub repository–complete with version history. This article explains why we chose Git Subtree over simpler approaches, the challenges we encountered, and how we implemented a mirroring solution in our CI pipeline.

Using Buildah over DinD for building container images

by Paurav Hosur Param, 7 August 2025

In our CI pipelines, we originally relied on Docker-in-Docker (DinD)–which worked, but not without its drawbacks. This article aims to clarify why DinD is not apt for container image builds and why we shifted to using Buildah instead.

Introduction to Svelte

by Archie To, 28 April 2025

ARCsoft recently came across a project that uses Svelte. The framework is pretty neat and it comes with many unique features compared to other frontend technologies. Let’s discover those features together in this article.

Splitting a numeric code in Python

by Drew Leske, 9 April 2025

Sometimes people do funky things with data. We have a use case where two two-digit codes are mashed together into a four-digit code, and we need to split them. These codes are stored as integers because, well, why not.

To Mock or Not to Mock - Mocking Unit Tests

by Lee Napthine, 14 March 2025

If you’ve ever written unit tests, you’ve probably encountered situations where a function depends on an external API, a database, or a cloud service. These things are difficult to control in a test environment. This is where mocking comes in.

Development updates for the DBSSIN library

by Lee Napthine, 28 February 2025

Over the last year, we’ve been adapting DBSSIN (Database-Spreadsheet-Ingestion) to better fit current projects, and it’s come with its share of development challenges. The ARCsoft team has been pushing the library forward, cleaning up the mapping system, and handling some unique security and access issues.

Advanced querying with Django

by Archie To, 24 February 2025

One of the most powerful features that come with Django is the ORM (object-relational mapping). It allows you to easily fetch data from the database by writing intuitive Python code. However, if you don’t know (maybe read a different article if you do), there is more to Django’s ORM than the simple objects.get and objects.filter. This article aims to take your ability to use the Django’s ORM to the next level.

Working with OpenStack

by Lee Napthine, 31 January 2025

Recently, I built a program that directly interacts with OpenStack cloud operations and its various components. It was a solid learning experience, and I want to share what I learned so future ARCsoft developers can hit the ground running.

Background and context for the Software Development Guidelines

by Drew Leske, 28 January 2025

It can take a while to learn a team’s culture, and there’s no quick solve for that: it’s the culmination not only of the group’s shared experience but the years of lived experience each individual brings in, and it evolves over time and is always unique. Expected practice, on the other hand, can and should be clarified–and if your team culture has “inclusion” as a core tenet, then setting clear expectations is essential to keeping everybody on the same page.

Strapper demo

by Archie To, 28 January 2025

STRAP is one of the most important projects that ARCsoft is working on. To deploy applications onto STRAP, we use a user-friendly web application named Strapper. Today, I will show you a quick demo of how we can have an application up and running with just a few clicks using Strapper.
