So you’re going to be an intern
After months of nerves, interviews and one too many LeetCode questions, you’ve done it. You’ve landed an internship, you’re free from the dread of a long, empty summer and your brain is filled with vague notions of what your internship might be like. I’m here to gather up your brain clay and sculpt it into solid ideas of what things will be like. Before we start, it needs to be… Continue reading

Engineering lessons from my SaaS startup
I’m now almost two months into my software engineering summer internship at FreeAgent. When I was 18, I chose to delay the start of my university course for 18 months to have a go at building a ‘Software as a Service’ (or ‘SaaS’) startup with two others. Our software, ‘trackio’, was a bring-your-own data platform that allowed sales teams to collect, connect and reconcile their disjointed data sources. It was… Continue reading
How to boost your confidence as a beginner software engineer
Every engineer has questioned at least once in their life whether they are skilled enough for their chosen field. I experienced these doubts when I started my computer science degree at university, and despite the fact that I got through the first three years successfully, I still wasn’t fully confident in my abilities when I started my internship at FreeAgent. However, this is entirely normal. Every engineer faces challenges on… Continue reading
An introduction to object-oriented programming
Object-oriented programming, or OOP, is a programming paradigm centred around the concept of objects. This article will aim to provide a basic understanding of objects, classes, OOP principles and various other concepts within the paradigm. Code examples will be mediated in the Ruby programming language, which is an example of an object-oriented language. In Ruby, any value is an object, even data types like String and Integer, which are often… Continue reading
Hiding Elements on the Web
For many of us the word hiding has visual connotations. But remember that the web is perceived both visually and non-visually. In this talk, Laurence Hughes from our Design System team explains that hiding is a tricky front-end development technique, used for both user interface experiences and accessibility-related purposes. He also provides some tips on how we can avoid doing DIY hiding completely. https://youtu.be/AZ6uw4KCOQA Continue reading
Titlecase, underscore and laser guns
Not so long ago, I had an opportunity to peek under the hood of titlecase and underscore methods, the tiny cogs of the “Rails magic” machine. The latter turned out to be a very interesting function—a lot of hard-to-follow transformations, secret injections and the like. All of these bits significantly contributed to an odd-looking bug I’ve been working on. Today, we’ll unravel the implementation of both methods and look in… Continue reading
Engineering Principles at FreeAgent
Culture is an inherent part of every organisation. It lives and breathes. In our engineering organisation at FreeAgent there are now over 100 fabulous people. It is these people and the culture we have built that are consistently recognised as our two most important strengths. They're also what we fear losing the most. There is a natural cycle of cultural onboarding for new people joining our organisation. In their first… Continue reading
Timecop vs Rails TimeHelpers
TL;DR - You probably can’t replace Timecop with Rails' built in TimeHelpers, as TimeHelpers only recreates Timecop’s freeze method, and can’t handle nested travelling. Timecop is the go-to gem for testing time-dependent code, as it allows you to manipulate the current time during test runs. This is important because without control over the time, flakey tests can emerge in your codebase. A very simple example is testing the created_at attribute… Continue reading
Testing Child Processes in Ruby
I was recently writing a piece of code that we wanted to act as a supervisor of child processes. We wanted to ask this supervisor the following “Hello there, would you mind running this task in a child process? Thanks!”. From here the supervisor would create a process, keep track of it so we can stop it if necessary, and run the given piece of code in it. This supervisor… Continue reading
