Qvault is run by Gophers – people who love the Go programming language. A good portion of our content is focused on helping our readers become the best Go devs they can be.
I often hear that we need more and better comments in the code we write. In my experience at previous companies as well as at Qvault, we often need better comments, we rarely need more, and often we need less. Before you crucify me for my sacrilege, let me explain. #1 – Incorrect Comments Incorrect … Read more
Constants can be confusing and easy to misuse in Go if you are coming from an untyped language. Let’s take a look at some of the nuanced details of how they work in Go. It’s probably unsurprising, but Go’s constants are almost nothing like JavaScript’s bastardized version of the concept. Go vs JavaScript Many programming … Read more
You’ve probably visited a site and attempted to sign-up only to be met with errors such as: Password needs a capital letter Password needs a special character Password needs to be at least 8 characters I just released a package in Go that solves this problem. Check it out and give it a star here: … Read more
I’ve recently been working on a Rust course for the Qvault app. In order to write a more engaging course, I want students to be able to write and execute code right in the browser. As I’ve learned from my previous posts on this topic, the easiest way to sandbox code execution on a server … Read more
Coding languages, tools, and frameworks are in a constant state of flux, improvement, deprecation, and popularity swings. Let’s take a look at the top 4 languages for new programmers to learn in 2020. As it happens, we support all four of the top languages on the Qvault app, and have courses for JavaScript and Go, … Read more
I lead a team that is responsible for anywhere from 15-25 Go microservices at any given time. We are constantly creating new services and libraries, so it’s become important to streamline the boilerplating process. I’m mostly writing this article for myself as a kind of self-documentation, but hopefully, you’ll find it useful as you create … Read more
We’ve recently made big changes to how we execute Go in the browser on Qvault and want to explain the enhancements. Web Workers are the reason we’ve been able to solve some of the serious browser-related coding problems that were holding us back. Consider this article a sequel to Running Go in the Browser with … Read more
I’m normally a fan of the rigidity within the Go toolchain. In fact, we use Go on the front and backend at Qvault. It’s wonderful to have standardized formatting, vetting, and testing across the entire language. The first real criticism I’ve had is with the way Go modules handle major versions. It’s over-the-top opinionated and … Read more
We’ve launched our new Big-O Algorithms course! We wrote this course for engineers who need a refresher on computer science basics, or want to learn the fundamentals for the first time. The study of algorithmic complexity is often overlooked by new developers, and we’ve found that get-rich-quick boot camps often skimp on these details. It’s … Read more
Pure functions are often hyped up in the JavaScript world, probably because of the abundance of stateful front end applications. While pure functions have their downsides (i.e. inconvenience, potentially large argument lists), they should be used as much as reasonably possible. We’ve made a lot of changes in the Qvault app codebase recently to use … Read more
