Welcome to Technology Short Take 197! I’ve been traveling for business for the last week, so this Technology Short Take has a tad fewer links than I typically include. Even so, I still have links on radical new network designs, the impacts of AI on code security, things beginners get wrong about AWS IAM, and more! Let’s get into the content. Networking This story about a radical…
Welcome to Technology Short Take 196! Just in time for the US Memorial Day holiday, I am back with another list of articles related to various data center technologies like networking, security, operating systems, and applications. You will find articles on VPNs, Linux local privilege escalation (LPE) vulnerabilities, browser quirks and workarounds, the death of Terraform (again), and so much…
Welcome to Technology Short Take #195! It wasn’t planned this way, but it seems like this Tech Short Take is heavily slanted toward AI/LLM-related articles and posts. Topics like security concerns around improper storage of API keys, how developers are using AI tools, spyware getting installed with AI assistants, and how AI/LLMs might be creating barriers to entry for new IT profesionals are…
This is Technology Short Take #194, the latest in my semi-regular series of posts sharing data center technology-related links and articles from around the web. What have I gathered for readers this time? Key topics in Tech Short Take 194 include a new cryptography-based network stack, a look at why folks are revolting against AI, and an in-depth comparison of microVM technologies. On to the…
Welcome to Technology Short Take #193! I know it has only been a couple weeks since the last Tech Short Take, but I am guessing that readers won’t really mind another one. Here is my latest collection of articles and posts about data center-related technologies. Enjoy! Networking Brian Linkletter shares his 2026 list of network simulators and emulators . (Hat tip to Ivan P. for the link.)…
Heard about Pulumi, but aren’t sure what it is? Maybe you know a little bit about Pulumi—like that it does infrastructure as code (IaC), but using general purpose programming languages—and you’re wondering where it fits in a larger automation framework? Or maybe you’re a network engineer just starting to dabble in network automation, and you’re wondering if this…
Welcome to Technology Short Take #192! Who’s interested in some links to data center technology-related articles and posts? If that’s you, you’re in the right place. Here’s hoping you find something useful! Networking Interested in an autonomous network engineering agent powered by Claude ? (Hat tip to Russ S. for sending this my way.) Security Google’s Threat…
When I first started learning Kubernetes, I had the idea that observing the network traffic between a client system using kubectl and the Kubernetes API Server would be a useful thing to do. The source of the idea is unclear; I am unsure why I thought this would be useful as a learning tool. Regardless, I continued on with learning Kubernetes and never really pursued this idea—until this…
Like perhaps some readers, I am quite particular about what gets installed on my systems. I try to keep my systems as “clean” as possible, doing my best to avoid tools that have an extensive list of dependencies that must be installed and updated. Where that isn’t possible—such as with the Azure CLI, which has a massive number of Python modules that are required in order…
Welcome to Technology Short Take #191! This is my semi-regular collection of links related to technology disciplines, including networking, security, cloud computing, storage, and programming/development. I hope that I’ve managed to curate an interesting and useful set of links for readers. Enjoy! Networking I learned a new acronym from Ivan Pepelnjak in his article on “not so…
Welcome to Technology Short Take #190! This is the first Tech Short Take of 2026, and it has been nearly three months (wow!) since the last one. I can’t argue that I fell off the blogging bandwagon over the end of 2025 and early 2026. I won’t get into all the reasons why (if you’re interested then feel free to reach out and I’ll fill you in). Enough about…
If you need to work with BGP in your AWS VPCs—so that BGP-learned routes can be injected into a VPC route table—then you will likely need a VPC Route Server. While you could set up a VPC Route Server manually, what’s the fun in that? In this post, I will walk you through a Pulumi program that will set up a VPC Route Server. Afterward, I will discuss some ways you could check the…
Welcome to Technology Short Take #189, Halloween Edition! OK, you caught me—this Tech Short Take is not scary. I’ll try harder next year. In the meantime, enjoy this collection of links about data center-related technologies. Although this installation is lighter on content than I would prefer, I am publishing anyway in the hopes of trying to get back to a somewhat-regular cadence.…
Every now and then, I publish one of these “Posts from the Past” articles that looks back on content I’ve created and posted over the life of this site. This year marks 20 years of content—I can hardly believe it! Don’t worry, though; you won’t have to go through 20 years of past posts. Here is a selection of posts from mid- to late October over the last decade…
A while ago I wrote an article about linting Markdown files with markdownlint . In that article, I presented the use case of linting the Markdown source files for this site. While manually running linting checks is fine—there are times and situations when this is appropriate and necessary—this is the sort of task that is ideally suited for a Git pre-commit hook . In this post,…
