Why iPerf3 Should Be in Every Network Engineer’s Toolkit

There’s something deeply satisfying about proving your network is actually fast instead of just hoping it is. That’s where iPerf3 comes in. Setting up a simple performance test from a Windows 10 laptop to a Ubuntu 26 server gives you a real-world way to validate throughput, latency behavior, packet loss, and overall network stability. Better yet, throwing a Windows 11 VM into the mix inside that Ubuntu host adds another layer of realism that mirrors modern production environments where virtualization is everywhere.

Sunday/Funday - This is what happens when Bacteria meets whisky 🦠🥃

 Video from https://x.com/HowThingsWork_

Whiskey has a funny relationship with bacteria. On one hand, a strong enough alcohol concentration can absolutely ruin a bacterium’s day. That’s why alcohol is used in disinfectants and hand sanitizers. But before anyone starts pouring whiskey on every scrape like an old-timey cowboy doctor, most whiskey sits around 40% alcohol — good for cocktails, not exactly hospital-grade sterilization. So while whiskey might make some bacteria uncomfortable, it’s not marching into battle like a tiny microscopic action hero.

Why Python Is Becoming Every Network Engineer’s Secret Weapon - thenetworkdna.com

If you’ve ever spent hours hopping from one device to another just to push the same config change, this article is a great reminder that there’s a smarter way to work. The piece breaks down network automation with Python in a really approachable way, showing how engineers can move beyond repetitive manual tasks and start using code to handle configurations, monitoring, and troubleshooting at scale. It takes what can feel like a complicated topic and makes it practical, focusing on real-world use cases instead of drowning readers in theory. 

Why Network Alerts Are Your First Line of Defense

One of the easiest ways to level up your network management game is by enabling alerts—yet it’s also one of the most commonly overlooked steps. Whether it’s a syslog message, an SNMP trap, or a simple email notification, alerts turn your equipment from passive hardware into active participants in your operations. Instead of waiting for users to complain or stumbling across issues during routine checks, alerts give you real-time visibility into what’s happening behind the scenes. In short, they close the gap between “something broke” and “you know about it.”

How to text with a $30 Radio Board

Imagine sending a text message to someone hundreds of miles away — no cell towers, no Wi-Fi, no cloud servers, no monthly bill. Thanks to the convergence of affordable hardware and open-source ingenuity, this isn't science fiction anymore. A cheap radio board, small enough to fit in your palm, is all the hardware you need to step completely outside the bounds of traditional telecommunications infrastructure.
