It was quite a long time ago now that I started HLS-Stream-Creator, and I've previously released an example of automating HLS-Stream-Creator so that it receives and processes workloads.
I never really expected that I'd actually have much practical use for HLS Stream Creator when I created it (I created it as a means to learning about HLS in advance of a 2nd interview), particularly as I wasn't generating/publishing any video at the time.
Over time, though, that's changed and my needs have grown from occasionally invoking the script to wanting the convenience of having a dedicated muxing pool so that I can simply submit a video and have it come out in HTTP Live Streaming (HLS) format (particularly useful now that I have videos.bentasker.co.uk).
Although I'm not going to focus on the Command and Control aspect (at it's heart it's a simple REST API) in any depth, this documentation will detail the process I followed in order to have 3 Raspberry Pi's PXE boot and run HLS-Stream-Creator as a service in order to receive arbitrary videos, calculate the output bitrates and then generate HLS output.
It's as much an opportunity to document the process I used to PXE boot Raspberry Pi's with a NFS root filesystem.

I previously posted some documentation on how to build a DNS over HTTPS (DoH) Server running Pi-Hole and/or Unbound.
There's another standard available, however - RFC 7858 DNS over TLS (DoT)
DoT isn't as censorship resistant as DoH (as it's easier to block), but does provide you with additional privacy. It also has the advantage of being natively supported in Android Pie (9), so can be used to regain control of your queries without needing to run a dedicated app link Intra, with all the issues that might entail.
In this documentation we're going to trivially build and place queries against a DoT server.

I've run my own mail server for quite some time, but it's started to reach the point where a refresh is probably in order.
Normally, I'd prefer to build from scratch, but I thought, this time, I'd have a look at some of the "off-the-shelf" solutions that now exist. Mailinabox was quickly discounted because there's no real configurability, which doesn't sit well with me (it does simplify installation, but makes long-term management that much harder).
iRedMail seems to have a reasonable following, and a scan of it's website and documentation suggested that it is, at least, reasonably sane.
This documentation details the process I followed to install iRedMail on Debian 8 (Jessie). I used Jessie rather than Stretch (9) because that's what the VM I was repurposing was imaged with.

The key for both the Saab 93 and 95 is essentially a large plastic sheath around a hidden key with some rubber buttons on the front.
Unfortunately rubber has a tendency to degrade over time, and the buttons eventually either fall out, or collapse in.
Replacement of the keycase is quick and easy, though, this documentation details how to do it, including replacing the battery. For those who prefer following a video, there's also a video tutorial at the bottom of the page

The ASUS/Google Nexus 7 suffers from an issue where the USB charging port wears out, so the charger no longer makes proper contact and the device won't charge. The headphone socket (which is on the same board) can also fail.
In order to repair this, a small board must be replaced (which will mean replacing the headphone port as well). Replacement boards are available on Amazon for about £8. It's a pretty straightforward process, and doesn't require any special tooling.
This documentation will walk you through the necessary steps (there's a video at the bottom for those who'd prefer a video guide) to remove the old USB charging port and install a new one.
