Fun with IP Address Parsing (dave.tf)
In my quest to write a fast IPv4+6 parser, I wrote a slow-but-I-think-correct parser, to use as a base of comparison. In doing so, I discovered more cursed IP address representations that I was previously unaware of. Let’s explore together!

Hybrid Cloud – The Worst Possible Option (adatosystems.com)
The sheer horrific nature of hybrid networking might not be intuitively obvious to folks reading this because we live and breathe in a technical context every day. So let me draw a parallel that might make it clearer: hybrid cars.

Nix Trigonometric Math Library from Ground Zero (lantian.pub)
I wanted to calculate the network latency between all my VPS nodes, and add the latency into the configuration file of Bird BGP daemon, so the network packets are forwarded through the lowest latency route. However, I have 17 nodes as of today, and I didn't want to manually run a ping command between each pair.
