I thought I posted about this, but I didn’t (below are some related NTFS partition posts that ammend this one): moving an NTFS partition on a disk to make space so you can resize another disk partition.
Simple case: moving a Windows Recovery Partition to the end of a disk
For simple cases when you can afford losing or reconstructing data, or restoring data from back-up, you can use the existing tools DISKPART (TUI) or DiskMgmt (GUI)
For the specific case of the Windows Recovery Partition, this involves running reagentc /disable at the beginning of the process and reagentc /enable at the end.
See:
Complexer case: moving an NTFS data partition while keeping the data
I had this disk layout:

This is interesting as it will help us combine the outside lights with one or more motion/light sensors: [Wayback/Archive] BJS 214 – Arnold-Schalter (this is the Busch-Jaeger® compatible version; for different installation systems like Gira and Jung, look at their site: [Wayback/Archive] Produktkategorien Privatkunden – Arnold-Schalter).
Basically it is a multi-function switch that to combine lights and separate motion sensors:

Some combinations of hardware/OS will result in high FAN speed despite low power usage on Dell R730/R730xd systems.
For me, altering the BIOS or iDRAC thermal settings did not solve it, nor did updating all firmwares to the most recent versions, so I went digging further.
Below are some links in case I want to resolve that (after figuring out that Dell R730 and R730xd are 13G systems).
There are lots of quotes in them as it will help me find back the information later on.
Note to self: I really wonder what the difference between raw 0x30 0xce and raw 0x30 0x30 is (I think 3rd party PCIe support and forced fan speed level) and how they differ from the system.thermalsettings.ThirdPartyPCIFanResponse setting.

Interesting: [Wayback/Archive] Low Power current measuring with Nordic Power Profiler Kit 2 – YouTube
It’s a review of [Wayback/Archive] Power Profiler Kit II – Get started – nordicsemi.com.
The Power Profiler Kit II (PPK2) is a standalone unit, which can measure and optionally supply currents all the way from sub-uA and as high as 1A on all Nordic DKs, in addition to external hardware.

Just in case I ever want to migrate a repository from SourceForge to GitHub: [Wayback/Archive] ipmitool/sf2gh: migrates tickets to GH from SF
This was developed for the Gene Ontology but is generic and will work for any project.
The project consists of two files, the extensive [Wayback/Archive] sf2gh/README.md at master · ipmitool/sf2gh · GitHub which has a very important tip:

Not using vim much, so every time I need it for more complex things than basic editing or leaving any vi based text editor (hello <Esc> :q!), I need a FAQ or cheat sheet.
I like this one the most as it has merged most if not all other cheat sheets in it: [Wayback/Archive] ikwyl6 vim cheat sheet.
The above page is the [Wayback/Archive] CDN for your source code | raw.githack.com hosted version of the HTML page in the repository [Wayback/Archive] GitHub – ikwyl6/vim-cheat-sheet-html: Collaboration of vim cheat sheets I’ve found and put them in a html file.
That means you can contribute to it with more vim features in case they become available.
By intent, the cheat sheet looks like [Wayback/Archive] Vim Cheat Sheet – vim.rtorr.com, but it omits the tips bits like:

[Wayback/Archive] amp8888 comments on PSA: The ASUS Hyper M.2 x16 Gen 4 Card Is VERY Long (~27cm) via [Wayback/Archive] PSA: The ASUS Hyper M.2 x16 Gen 4 Card Is VERY Long (~27cm) : homelab
Just a quick PSA to everyone out there: the PCIe gen 4 version of the ASUS Hyper M.2 x16 card is very long, so take that into consideration if you’re planning to use them in a server.
Note at at 12.2cm, the card is also quote tall. This tool can be a problem on many 19″ rackmount systems. For instance on my Dell R730xd, I had to remove part of the aluminium chassis above PCIe slot #4 in order to make the card fit. This was easy using a set of pliers and does not interfere with any of the mounting mechanisms.
Older versions of the ASUS card are smaller, but cannot do PCIe 4.0:

Onze druiven hebben een sterk wisselend gehalte aan pectine, daarom onderstaand wat linkjes zodat een volgende badge jam hopelijk een consistenter resultaat aan dikte geeft.
Pectine lost niet makkelijk op en kan klontjes geven. Daarom is het vaak makkelijk om het met een heel klein beetje water tot een gelijkmatige pasta te roeren en dan pas aan je kokende fruitmengsel toe te voegen.

I got a “The signed image’s hash is not allowed (DB)” when booting an OpenSUSE Linux ISO Image:
[Wayback/Archive] p.png (624×351)
It was the signed image ftp.uni-kl.de/pub/linux/opensuse/distribution/leap/15.5/iso/openSUSE-Leap-15.5-DVD-x86_64-Build491.1-Media.iso which isn’t trusted by Hyper-V to perform UEFI secure boot.
Technically, the UEFI secure boot specifications support adding acceptable digital signatures in order to allow booting from media not signed by Microsoft, but alas, Hyper-V does not allow that option as per [Wayback/Archive] Secure boot with custom keys – Microsoft Q&A.
The not so satisfying solution is to turn off secure booting for this particular VM in Hyper-V from the VM-options (Ctrl-O) menu with the steps below.

Despite, or maybe thanks to, being a duplicate I like this [Wayback/Archive] command line – How can I view all Wi-Fi network names (SSIDs) in my area in the terminal? – Ask Different (thanks [Wayback/Archive] Jandroid and [Wayback/Archive] Ray de Groat)
The reason is that unlike similar questions it has a single answer that works on more recent MacOS versions:
system_profiler SPAirPortDataType
I usually amend it with | less for easier browsing.
It means this question skips all kinds of answers with commands that over the course of time Apple has decided to kill and now no longer work or only work as admin:
