20.04 Random & Frequent Reboots - No detectable reason
de flag

We recently deployed some new hardware and since Day 1 have been experiencing random reboots, an a lot of them. I've actually been working at the console and it's just rebooted without any warning.

We've gone down a bunch of rabbit holes trying to troubleshoot, but so far nothing has panned out. It's happening on multiple devices which makes me tend to think that it is not a hardware problem wi ...

I'm using Kubuntu 21.04 on a Trekstor SurfBook W2 laptop and the bluetooth is not working. I think the adapter is not even detected correctly. Not 100% sure but it might be a Broadcom Wifi/Bluetooth adapter. The wifi works fine.

Automatically switch to screen built-in speakers when available
fr flag

I have a two screen setup, each screen with their built-in speakers. All works well except for sound setting automatically switching to digital output every time the screens goes off after which I have to set them back in the setting.

I could go around this and switch off any power-saving/security locks, but I'd really prefer not to with three kids at home. I already have switch-on-port-available

Is user@host at the end of each key in authorized_keys necessary?

I have a set of 8 small servers that chat with each other over ssh logging in automatically.

Now I would like to have the .ssh directory of all the servers be identical.

Documentation for pre-2.9 releases of maas for 18.04 server

I am experimenting with Maas to see if we can provision 32-bit clients which cannot run the 20.04 image which it appears the latest version of Maas uses, so I am working with a 18.04 server image where Maas 2.4 is available in the apt repositories. It also appears that 2.8 is the latest version supporting Ubuntu 18.04

Unfortunately it seems that the maas.io web site only presents 2.9+3.0 documen ...

This worked perfectly on Ubuntu 20.04.

Xubuntu: How to prevent Thunar from auto-opening a specific usb thumb drive?
de flag

I have one specific usb thumb drive that I use to store a git repository. When I plug it in, I'd like it to mount automatically, but without opening a Thunar window showing the content of the thumb drive. I only use git push and git pull commands to access the contents of the drive, so a popping up Thunar window just blocks my workflow.

Just to emphasize: I do want Thunar to open up every time I st ...

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
