All Problems Are Hardware Problems

When I was a lad in high school I worked for Walmart. I learned quite a bit about retail at my early age but one of the fascinating things I used in the late 1990s was a wireless inventory unit, colloquially known as a Telxon. I was amazed by the ability to get inventory numbers on a device without a cable. Since this was prior to the adoption of IEEE 802.11 it was a proprietary device that only worked with that system.

Flash forward to the 2020s. I went to Walmart the other day to look for an item and I couldn’t find it. I asked one of the associates if it was in stock. They said they could check and pulled out their phone. To my surprise they were able to launch an app and see that it was in stock in the back. As I waited for them to return with the item I thought about how 25 years of progress had changed that hardware solution into something software focused.

Technology Short Take 157

Welcome to Technology Short Take 157! I hope that this collection of links I’ve gathered is useful to someone out there. In particular, the “Career/Soft Skills” section is a bit bigger than usual this time around, as is the “Security” section.

Networking

• Interested in understanding how NAT Traversal works? David Anderson’s post on how NAT Traversal works should help.
• This happened a couple of months ago, but I don’t think I’ve linked to it in a Technology Short Take: the Envoy Proxy open source project announced Envoy Gateway, a “new member of the Envoy Proxy family aimed at significantly decreasing the barrier to entry when using Envoy for API Gateway (sometimes known as ’north-south’) use cases”.
• This is a slightly older article from Ivan Pepelnjak on using netsim-tools to build Vagrant boxes, but let’s be real—his stuff is kind of timeless anyway, right?

Security

• Tal Maor, along with Nirit Tyomkin, describe moving laterally between Azure AD-joined machines.
• Phil Stokes of SentinelOne describes some of the early security changes found in macOS “Ventura” (i.e., macOS 13).
• Falco recently (at the start of June) released version 0.32.0, which included a number of fairly significant changes. Read more Continue reading
