My current workflow to create the weekly reading posts đź”—Here is a breakdown of the simple, automated, and edited workflow I currently follow every week:
1. Capturing and Collecting Links 🔗I use Raindrop.io as a Google Chrome extension and mobile app to save the links I found interesting into a dedicated collection named “00-current”. This collection is configured to be the default saving location for all new bookmarks.
2. Processing (Sunday) 🔗 I export all the bookmarks saved in the “00-current” collection as a .
Another week goes by, another collection of links I found interesting…
Infrastructure and Operating Systems đź”— FreeBSD Officially Supported in OCI Runtime Specification v1.3 - The Open Container Initiative (OCI) Runtime Specification v1.3 officially includes FreeBSD support.

What Edu is Reading This Week đź”—People often ask me about the cool stuff I stumble upon during the week. So, I figured, why not share the links that caught my eye? So here we are.
This is inspired by some newsletters I read such as Vermandeen’s Valuable News or Kube Today.
I’m not 100% sure if I’ll be able to keep a weekly cadence; I really don’t have too much free time lately, but I’ll try!
I wanted to simulate a RedFish BMC to be able to power on/off libvirt virtualmachines and attach ISOs as I do for baremetal hosts.
Entering sushy-tools đź”—sushy-tools include a RedFish BMC emulator as sushy-emulator (see the code in the official repo).
Basically it can connect to the libvirt socket to perform the required actions exposing a RedFish API.
metal3-io/sushy-tools container image đź”—To easily consume it, the metal3 folks already have a container image ready for consumption at quay.
