## AI overview

Technology Short Take 194 curates data center technology links covering Reticulum, IPv6 networking, security exploits and vulnerabilities, TLS and QUIC diagrams, Kubernetes security, Claude Code advisories, AWS emulation, and developer tools.

## Source excerpt

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 content! Networking This is cool. Longtime reader Todd Smith pointed me to Reticulum, a new cryptography-based network stack. Todd also spent some time messing around with Reticulum and shared his findings in two blog posts: first, an initial/introductory post, followed by a post sharing his experience with some Reticulum experiments. Scott Hogg examines building an IPv6 training and testing lab. Security eBPF is taking hold in security exploits, like the tool named "BPFdoor" that is penetrating critical infrastructure networks. Paul Meyer discusses reproducing and mitigating BadAML, an ACPI-based attack vector that can be used to potentially gain access to confidential VMs. Meyer admits that the model in the article assumes the attacker has full control over the host, at which point I would assume "game over" and move on. This site provides not only an illustrated TLS 1.2 connection diagram, but also offers diagrams for QUIC, DTLS, and TLS 1.3 (see the links in the upper right corner). Rory McCune continues his series on unpatchable Kubernetes vulnerabilities. David Chisnall posted a scathing analysis of Mythos on Mastodon (hat tip to Bruce Davie for boosting it into my timeline), and shared a link to an advisory on critical command injection vulnerabilities in Claude Code. Cloud Computing/Cloud Management I recently found this alternative to LocalStack for AWS emulation. How to hide regions and services in the AWS console is a useful thing to know about. Operating Systems/Applications Chris Down breaks down the differences between zswap and zram. Micah Kepe introduces his new
