+My dad has an old Panasonic MiniDV camcorder and wanted to import old tapes into his cutting tool
+on Windows 10. After hooking up the camcorder via Firewire, the import dialog showed the time code
+of the running tape, but instead of the video, the preview was black and there was no audio.
+
+To make sure it isn't a problem of the software, we tried [VirtualDub](http://virtualdub.org/) -
+with the same result.
+
+After some googling, it seems as if Microsoft removed parts of the Firewire IEEE1394 driver. And
+those parts seem to be necessary for these old camcorders.
+
+Luckily, they offer a "Legacy" driver for downloading:
+
+* https://www.microsoft.com/en-us/download/details.aspx?id=44218
+
+This will download a `1394_OHCI_Legacy_Driver.msi`. Double-click to install it.
+Afterwards, you'll find a new folder `C:\Program Files (x86)\1394 OHCI Compliant Host Controller (Legacy)\`.
+
+In there, depending on your PC, enter either the `x86_driver` or the `x64_driver` folder, right-click the
+`Legacy1394.inf` file and select **Install**.
+
+After installation, open your Device Manager, find the section "IEEE 1394 Bus host controllers" and open it.
+Find your Firewire card, right-click it and select **Update driver...**. Select "Browse my computer for
+driver software", then "Let me pick from a list of device drivers on my computer" and find the driver for
+**Generic 1394 OHCI compliant host controller (Legacy)**. Select that and click "Next" to install it.
+
+That's it - you should be able to import video now.

+After some years, my IKEA Markus chair developed some clicking/knocking noise whenever I swivel in
+it. This was very annoying for everbody in the same room.
+
+All posts and videos I found about problems with these chairs were talking about re-greasing the
+swiveling mechanism under the seat. However, there were a lot of people that also reported, that
+that didn't work for them.
+
+After digging some more, I finally found [this video](https://www.youtube.com/watch?v=L2YyqZ5K9n4).
+This demonstrates how to disassemble parts of the gas cylinder. In there, you'll find a few washers,
+a ball bearing and a rubber stopper. In my case, the washers had deep grooves in them and the
+shavings were clogging the ball bearing.
+
+I cleaned everything up, greased the ball bearing and assembled it with the washers upside down,
+so the sides without grooves are now pushing against the ball bearing. And that did it. I now
+have a quiet chair again.
+
+**nb:** At least in Germany, IKEA Markus chairs have a 10 year warranty. So you might as well just
+return it and get a new one.
