How to get Ruby on Rails working with PostGIS and PostgreSQL on Fly.io

Very soon Fly will become a contender to fully replace Heroku and will be much more simple and easy to use than something like Kubernetes or any of AWS's offerings. Right now, it's great for hobbyists or a team with one or two developers.

In this article, we will explore the usefulness of GPT-3 for developers by examining its performance in handling three common challenges that they may encounter in their work. These challenges include generating new code, explaining unfamiliar code constructs, and deciphering unusual error messages.

The what could be described as a cross-platform solution for mobile development. But, there is a big difference between a cross-platform solution and Kotlin Multiplatform Mobile.

Building full-stack monorepo's doesn't have to be a headache. With the T3 stack we can quickly spin up full-stack, typesafe Next.js projects.

Package management can be something of a headache, but it doesn't have to be that way. Here's some tips to get you on your way with Maven Central.

Unit tests for APIs can sometimes provide little to no value, so the next logical step is often to write integration tests. You don’t want to touch live data though, and want tests to make assertions against actual (un-mocked) service logic. The following is an approach to do just that.

The goal of risk management is to minimize risk in a technical project by minimizing the probability of failure and minimizing the impact of failure.

If you’ve ever been interested in complex typings in TypeScript, particularly when it comes to typeguards, this is the article for you!

We talk about Microsoft's dependency injection package TSyringe and its different dependency scopes. We explain how to use resolution scoped dependencies over transient, singleton, and container scoped dependencies to limit the scope of a dependency to a single lambda invocation.

Learn how to be a good custodian of your Rust code by using the Criterion crate effectively.

What we're trying to do is break down our part one and two, how you can immerse yourself in this world to learn it the fastest and come to appreciate it. Let's talk about “do you have to care about the project or not?”

There is a better way.

If you've heard a lot about AI and machine learning, but don't understand it, this month's episode is for you.

Rust helps mitigate concurrency hazards by design, but it's still up to the programmer to construct their program logic thoughtfully so they can take advantage of the power of concurrent and parallel processing.

Taking the time to write meaningful comments while providing feedback to your coworkers can go a long way. Yves shares some of the principles he follows to articulate positive criticism during code reviews.

This week we released a Github project called web-blueprint that documents our practices and opinions on web development. If you're a prospective client or hire, our hope is that you'll learn a little bit more about what web engineering at Rocket is all about.

We recently completed a project with one of the largest affiliate marketing consulting firms in the US which turned out to be a great success for everyone involved. We asked one of the lead consultants on the project, Jason Lombardo, to answer a few questions.

Our project began with a small ask: build a small Python back-end using AWS Lambda and API Gateway (with just a handful of endpoints to support a few pages) and use Serverless [https://serverless.com/] to manage the Cloud Formation setup. Not very involved, not much code, not even much configuration for the deploy. Next came authentication. In pursuing the joint dreams of DRTW ("don't reinvent the wheel") and WALCAP ("write as little code as possible"), we selected AWS Cognito over other opti

With DevOps at DEPT, one of our primary goals is to make the life of the developer easier. A specialty of ours is assisting in our customer's deployment process.

Nowadays just about everyone, everywhere, regardless of age and ability, uses a smartphone. With that in mind, it’s more important than ever to consider all the different ways to make your app accessible to everyone to ensure an inclusive experience. In this series, we’ll be discussing different ways iOS developers can make their apps more accessible. First up, we’ll be talking about Dynamic Type. Dynamic Type is a feature on iOS that enables the app’s content to scale based on the user's

At DEPT, we use a variety of tools to provision infrastructure in the cloud. In this post, we take a look at some of the reusable patterns we've developed using AWS CloudFormation.

In this post, we'll define GitOps, review a sample Terraform app module repo and an associated GitHub Workflow to lint and version the module repo, and review a sample Terragrunt live repo and a GitHub Workflow to apply infrastructure changes.

In this post, I’ll dive into some of the technical challenges of AR as well as our preferred solution, focusing on integrating Unity into an iOS project.

We were recently transitioning a client to use Heroku build pipelines for their Next.js project that handles most business logic through an external API, including authentication and cookie handling. This pipeline uses Heroku's review apps [https://devcenter.heroku.com/articles/github-integration-review-apps] as well as separate instances for staging and production environments. The client handled their domains through AWS's Route 53 [https://aws.amazon.com/route53/] DNS service. Pointing thei

The following presentation was transcribed from “SQL and Python for Product Managers” webinar, presented by Colorado Product Meetup and senior software engineer, Brian Schiller. It has been edited for clarity.

To help others as they make their way through this process, we decided to document and release our findings as a FreeRTOS tutorial for developers. Here is how to create a Hello World application.

Apple delivered several exciting and innovative new APIs for developers at WWDC this year. You might have heard or read about the SwiftUI and Combine revamp, but I want to address the new world of native WebSockets! The historically complicated connection protocol is now delivered as a first class citizen! Before we dive in on how awesome this is, it's important to have a basic understanding of Sockets and the road we've traveled to reach this point. What is a socket? By definition a socket is

AWS tags are key-value labels you can assign to AWS resources that give extra information about it.

The challenges discussed in this entry are specifically relevant to individuals that have roles in engineering leadership, user interface architecture, and design systems engineering.

So, you are about to build a new app and you need at least part of it to update in real-time. Well, we live in a modern world so it’s pretty common to have at least a part of the app update without requiring a user interaction or a page (re)load.

In this post, we’ll be comparing C++ with Rust, sharing our thoughts on when you should use each language, and predicting the future of C++ vs Rust.
