An Engineer's Guide to DynamoDB

When designing new systems, one of the key considerations of each system is how the data will be stored and queried. While most of our major products and services still primarily store data in a traditional relational database management system (RDBMS), our migration from a traditional monolithic web application to a microservice-based architecture has enabled our Engineering teams to use purpose-built databases as an alternative data storage solution for critical functions of the KnowBe4 platform.

Building a DevOps Culture, One Developer at a Time

As physical infrastructure has transitioned more and more to cloud and Platform-as-a-Service (PaaS) providers, engineering teams have had to adapt and address deficiencies in the developer and operations roles that traditionally worked in silos to build and deliver software.

Empowering a Cloud-Based Development Workflow with “On Demand” Environments that Match Production

How KnowBe4 solved the "It Works on My Machine" problem with a new approach to provisioning test environments.

On Rust's Option and Result Enums

This article will discuss Rust's Option and Result enums, and ways to work with them without using match. This came about because someone in our internal chat was lamenting how frequently they needed to use match. I found that I used match very frequently when Rust was newer to me, but now I use it much, much less.

Both of those enums have many methods that can often be used instead of match. I frequently refer back to the docs for Option/Result when I have an instance of one of those that I need to do something with. Specifically, I want to draw your attention to their methods that take an FnOnce. Let's go over some of those.
