User Research For Expert Systems

I’d like for you to think of your favorite app that you use almost every day. What do you use it for and why? Next, I’d like for you to think of the last time the app had a major design change that made you think, “What was the company thinking? Why would they change something that worked perfectly fine and make it so unusable? Did they not consult actual users before making this change?”

Elasticsearch vs. MongoDB

Elasticsearch and MongoDb are the two most popular distributed datastores used to manage NoSQL data. Both of these technologies are highly scalable and have document-oriented design at the core. There are differences between the two technologies, however, and it’s important to understand these differences in order to choose the right one for your use case. This blog post will examine the differences between these two technologies in a number of critical areas.

How to Import Kubernetes Labels as Tags | Datadog Tips & Tricks

In this video, you’ll learn how to turn Kubernetes node labels and pod labels into tags in Datadog in order to correlate metrics, traces, and logs back to Kubernetes deployments. Using labels for Kubernetes objects—such as pods or nodes—is key to organizing and making sense of your deployments. Datadog can automatically bring your Kubernetes labels from your clusters into the Datadog platform as tags, regardless of whether you’re using on-prem Kubernetes or a cloud-based service such as AKS, EKS, or GKE.

How to Use Browser Tests to Monitor Web App User Journeys | Datadog Tips & Tricks

In part 2 of this 2 part series, you’ll learn how to create Datadog Browser Tests to replicate user journeys and verify both that your web applications are responsive and functioning properly at all times. In part 1 of this series (link), you learned how Datadog’s API tests can be used to check API and website uptime. Datadog Browser Tests take this a step further, allowing you to replicate entire user journeys and transactions through your web applications. This is done with our browser recorder: simply click “Start Recording” and click through your application to record a test.

GrafanaCONline: Nissan Leaf -> cloud all the things

Come join me on an adventure to analyze and improve my driving behavior and driving routes to get the most range out of my all-electric Nissan Leaf. You will get to see how you can use Grafana, Cortex, Loki, and other amazing open source technologies on a $35 Raspberry Pi to process and store over 1000 messages/second from the vehicle CAN bus along with GPS data and even camera images!

GrafanaCONline: Slicing Kubernetes: Raspberry Pis, monitoring and chaos

Do you ever feel like your systems lack unnecessary complexity and overengineering? This is the talk for you. Join me as I detail the creation of a Raspberry Pi-based desktop Kubernetes cluster in an attempt to overcomplicate the already complex world of stateless web application deployment. We’ll walk through building an observability platform using open source tools like Prometheus, Grafana, and Jaeger to keep a close watch on our tiny fragile microservices and then break them intentionally for our own amusement.
