Add a -f to your umount and you can clear up those blocked processes. Sometimes you need to do it multiple times (seems like it maybe only unblocks one stuck process at a time).

When you mount your NFS share you can add the “soft” option which will let those stuck calls timeout on their own.

This was a separate outage unrelated to CrowdStrike a few hours earlier that took down a couple of airlines as well.

A majority of the VMs in the Azure CentralUS datacenter went down due to some sort of backend storage issue.

Edit: I guess I should have read the article they do say CrowdStrike. They seem to be implying that they were one event when the cloud services outage was earlier and unrelated. I had heard about grounded flights during the first outage as well. So they likely are combining the two events here.

I would think most wifi jamming is just deauth attacks. It is much easier to just channel hop, enumerate clients, and send them deauthentication packets.

This way you don’t need a particularly powerful radio/antenna, any laptop/hacking tool with Wi-Fi is all you need. There are scripts out there that automate the whole thing, so almost no deep knowledge of wifi protocols are required.

WPA3 has protected management frames to protect against this but most IoT cameras probably don’t support WPA3 yet.

Updates for CrowdStike are pushed out automatically outside of any OS patching.

You can setup n-1/n-2 version policies to keep your production agent versions behind pre-prod, but other posts have mentioned that it got pushed out to all versions at once. Like a signature update vs an agent update that follows the policies.

One nice thing about KDE compared to most of the other DEs is that the window manager (kwin) is separate from the underlying components, and it can be replaced!

There are many walkthroughs like this one out there: https://github.com/heckelson/i3-and-kde-plasma

You get i3 for tiling window management but you still get to use KDE’s system settings to do configuration like display settings, themes keyboard shortcuts, etc, just like you did before. You can also pick and choose which parts of the KDE desktop you want to keep (menu, krunner, etc)

Since i3 is just a window manager and is lacking all of that system level stuff it really rounds out i3 to feel like a full DE instead of having to piece together other tools to do those things.
