Now that we’ve defeated QNAP’s slightly broken udev, we can run a Docker container with rtl_433 in it to wire up our Vevor 7in1 weather station to Home Assistant via MQTT. First off, we need a Docker container running rtl_433, which assumes you’ve already setup the udev rule mentioned in the previous post, even if…
Configuring USB device pass through to Docker on QNAP NASes
So, this was a lot harder than it really should have been, especially because rtl_433 is a bit thingie about where the device appears in the /dev/ file system as an added sting in the tail… In my specific scenario, I was given a Vevor 7-in-1 wireless weather station for Christmas. They seem fairly solid…
Remapping Keychron K15 (QMK) media keys to control Sonos
Disclaimer: despite what people seem to assume when you buy a mechanical keyboard, I am not a keyboard fetishist. I’ve been using Microsoft Sculpts for over a decade because of historical repetition injury issues, and with Microsoft discontinuing the Sculpt and the new manufacturer taking their time taking over, all I want is a keyboard…
An Anki deck for Cisco Cyberops Associate CBROPS 200-201
I’ve recently been going through the Cisco Cyberops NetAcademy course as part of a TAFE unit I am doing at the moment. While working through the e-learning I took a bunch of notes, and then over the weekend I turned them into an Anki deck to help me prepare for the final exam. I’m actually…
An easier to parse version of “yum history”
I got interested today in trying to come up with a solid way of determining when updates were last applied to a RHEL-derived Linux instance. Previously we’d been inferring it from the kernel version, but it turns out there is a convenient “yum history” or “dnf history” command which will show you all the previous…
Amazon Linux 2023, DNS, and systemd-resolved — a story of no caching
I’ve learned a few things on an adventure this week, and I figure I should probably write them down. First off, AWS throttles the number of DNS queries you can perform on a VPC. Apparently you’re limited to 1,024 packets for Elastic Network Interface (ENI). I am a little unclear on if the limit is…
Leaders Eat Last
This is the first Simon Sinek book I’ve read. His stuff has been on my mental to do list for a long time, but never seemed to get to the top until now. This is about a book about how employee happiness and trust in their management directly results in better outcomes for employers, and…
Children Of Ruin
This book did not go where I expected it to. Sure, it has a species uplift plot which is similar to Children of Time, but that’s not all that’s happening here. If the previous book was about refugees and redemption, this book is about alternative ways of structuring societies (I don’t want to ruin the…
Solving the bottom turtle (the SPIFFE / SPIRE ebook)
I’m reading about SPIFFE / SPIRE at the moment in the form of the official project ebook. I’m going to list it here because if I read 194 pages I am going to write it up, regardless of if the book has been formally published or not. This book is probably the best introduction to…
Lights Out
This book continues the story of General Electric in the period after that covered by The Man Who Broke Capitalism, thus presenting an opportunity to validate if Jack Welch really was the bad guy while also learning more about where Welchism took General Electric in the longer term. This book is very readable, with nice…
