Application Observability in Kubernetes with Datadog APM and Logging - A simple and actionable example

Last year I shared an example on how to realize application tracing in Kuberntes with Istio and Jaeger. After that, the industry has made some substantial headway on this front and we are seeing more vendor support as a result. At Buffer, since we primarily use Datadog for Kubernetes and application monitoring, it's only fitting to complete the circle with Datadog APM and Logging. I had a chance to create a small example for the team and would very much love to share with the community.

Okay, without further ado, let's dive in!

Installing Datadog agent

First thing first, in order to collect metrics and logs from Kubernetes an Datadog agent has to be installed in the cluster. The Datadog team ma

True Color (24-bit) and italics with alacritty + tmux + vim (neovim)

This should make True Color (24-bit) and italics work in your tmux session and vim/neovim when using Alacritty (and should be compatible with any other terminal emulator, including Kitty).

Testing colors

Running this script should look the same in tmux as without.

Inserting Animated GIFs over Cells on Google Sheets using Google Apps Script

Overview

This script demonstrates how to insert an animated GIF over cells in a Google Sheet using Google Apps Script.

Description

I recently received a request to create a Google Apps Script for inserting animated GIFs into cells on a Google Sheet. I previously published a sample script on my blog on June 6, 2017. Ref In that script, the animation GIF was inserted using a public link. This new script leverages data URLs, which simplifies the process for using GIFs stored in Google Drive. Since this approach might be helpful to others, I'm sharing it here.
