Technology Short Take 160

Welcome to Technology Short Take #160! This time around, my list of links and articles is a tad skewed toward cloud computing/cloud management, but I’ve still managed to pull together some links on other topics that readers will hopefully find useful. For example, did you know about the secret macOS network quality tool? You didn’t? Lucky for you there’s a link to an article about it below. Read on to get all the details!


  • Ivan Pepelnjak tackles the “infrastructure-as-code is scary” mindset. (Related: see the first bullet in the “Career/Soft Skills” section below.)
  • Larry Peterson reflects on the evolution of TCP.
  • Vikas Choudhary discusses Istio’s Secure Naming; that is, the name given to services and the Subject Alternative Name (SAN) put on the X.509 certificates used in mTLS.



Cloud Computing/Cloud Management

Operating Systems/Applications

  • I loved this article by Lawrence Jones about how his organization tested and prepared for the impact of latency on their application. There’s some really good stuff in here.
  • Phil Stokes shares a few macOS “power tricks” for security pros.
  • Devbox looks insanely useful. I haven’t tried it yet, but do plan to try it out in the very near future.
  • Jean Yang opines that traffic-based tools leveraging eBPF are going to shake up the entire developer tools industry.
  • I should add this to my standard SSH bastion host OS image. (Also, I loved the story about the origin of the name.)
  • Here’s a walkthrough on using DNSCrypt on macOS.
  • Dan Petrov writes about the secret macOS network quality tool.
  • This article by Cecelia Martinez almost has me convinced I need to give the GitHub CLI a try (even though that is not the article’s primary purpose).



Career/Soft Skills

That’s it for this time around! If you have feedback for me—you want to suggest a new blog I should follow or check, or you have some constructive criticism that will help me make this site better—I’d love to hear from you. Feel free to reach out to me on Twitter, or find me in one of a number of different Slack communities (the Kubernetes and Pulumi Slack communities are good choices). Thanks for reading!
