## AI overview

Technology Short Take 191 is a curated collection of commentary and links covering networking, network automation, security, cloud management, containers, operating systems, applications, AI adoption, and software vulnerabilities.

## Source excerpt

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 passive" OPSFv2 interfaces in Cisco IOS/XR: QDS (Quick and Dirty Solution). I am totally using that from now on. Via Ivan (hat tip to my colleague Russ for pointing me in this direction), I also learned that all is not well in network automation land with Ansible. Although some parts of it are apparently now resolved, this does raise questions about the viability of Ansible for network automation. Doug Dawson talks about the new Amazon Eero Signal, a cellular backup to a primary broadband connection for users using their Eero mesh systems. I agree with Doug--the pricing seems high to me. I generally like the Eero devices, although there have been times when I really could use a bit more control over the settings. Security The APNIC blog features a guest article discussing the use of tunneling protocols to infiltrate networks. The article specifically discusses Generic Routing Encapsulation (GRE) and Virtual Extensible LAN (VXLAN). It's worth a read if your network uses either of these technologies. Cloud Computing/Cloud Management Somewhere along the way I missed the CDK deprecation announcement. If I am not mistaken, this leaves Pulumi as the only cloud-independent IaC tool that lets you use a general purpose programming language. Managing dependencies between containers can be difficult at times; this blog post by Nicolas Fränkel introduced me to wait4x, a tool one can use to help simplify these types of situations. Operating Systems/Applications I appreciated reading Mitchell Hashimoto's AI adoption journey. I feel it does provide a more realistic approach to how someone in a role like his m
