I wrote a tool recently that allows taking log files from the Cisco-managed S3 bucket, and outputs each log line as a Syslog message, with the content of the log line as a JSON-formatted message. Details of the Cisco-managed S3 bucket are here: https://docs.umbrella.com/deployment-umbrella/docs/cisco-managed-s3-bucket Once logged onto disk, the output of this tool looks like: […]

suspend-then-hibernate is a neat feature in systemd that allows a computer to suspend (aka sleep) for a period of time, then wake up, and hibernate. To configure this required a few steps on KDE Neon, though: Configure Hibernate To configure hibernate, you need to have a swap partition that is as large as your system’s […]
I’ve recently been playing with the Hyperscript (https://hyperscript.org/) tool, and I’ve been really liking it. I set myself the challenge of making a HTML form, and adding the ability to add tags to the form. So how might we achieve this? Lets start with a simple HTML form: Now how can we send the tags? […]
To backup my server I uses a tool called restic (https://restic.net/) – It’s great. I’ve recently been testing out using MEGA (https://mega.io/) as the backend storage for my backups, and to integrate that with restic, you use rclone (https://rclone.org/) as a storage driver. Sounds complicated, but it’s really not:restic –talks-to–> rclone –talks-to–> mega However, during […]

Note the version is v1.14.1 and the repo is archive.neon.kde.org Old Guide: I’ve been testing the new Wayland session in KDE Neon, and it’s working pretty great, but one […]
When trying to debug OSPF issues recently I found a set of excellent video tutorials from Darrell Root: https://www.youtube.com/c/DarrellRoot – I believe this is his website: https://networkmom.net/CiscoHandsOnTraining/ He has a playlist of videos called Cisco Hands-On Training: https://www.youtube.com/playlist?list=PLueKg14298FzreJSTGtMFIGdu10GLnT6z I found his videos super helpful, and a very clear explanation of how OSPF works, and how […]

We also look into how me can make messages quicker to distribute. For this code we use the trio functionality to wait for limited time for a task to complete, by using […]

We build out the functionality to receive messages, then distribute them to all connected users. For this part we use Trio’s nurseries to start up new running tasks: https://trio.readthedocs.io/en/stable/reference-core.html#nurseries-and-spawning We use the nursery.start_soon() function to kick off new tasks […]
