mdadm raid1 won't resize | --grow gives unchanged at
br flag

I've been trying to resize (--grow) this RAID array for a week and I know the answer is simple and probably staring me in the face, but I'm not sleep deprived and lost.

The array is RAID1 and used to consist of two 2TB hard drives and was not configured by me. The client ran out of space and I replaced the drives with two 4TB drives. I copied over the partition tables with sgdisk or something l ...

Restoring on Gnome-Disks a Disk Image (sda. Win + Linux) on an External Disk, which now doesn't boot

As I explain in the title, I've found some errors after previously successfully restoring from a Disk Image on Gnome-Disks to sda again, where Windows 10 was installed and I've added KUbuntu 18.04 with OS: 64 bit (which I have customized much). Ok, so, now I've tried to Restore this Disk Image (sda) with other destination: External Drive, and apparently I've succeeded, but it is no longer possible to bo ...

I have been using Ubuntu with my Dell Precisoon E5470 flawlessly, until I upgraded to version 21.10. The trackpad is simply not detected anymore, e.g. cat /proc/bus/input/devices does not list the trackpad. Any tips are welcome.

lc flag
Bas

I'm trying to install nvidia drivers on my inspiron 16 plus, with an rtx 3050. The laptop boots and works for a bit, but there are weird rainbow artifacts and then the screen dies.

The problem seems to be on both the 470 and 460 driver. I tried installing the drivers from the terminal, through the drivers menu and with the .run package, but they all have the same results.

Issues With Loading Pulse Audio
us flag

For an unknown reason, ubuntu creates a white noise with my mic. To solve this I added a command to start a noise cancelation to the pulse audio file, But that does not load at startup. To load it, I had to execute pulseaudio -k, and reload any applications using the mic such as Discord and OBS. The easiest way to run this automatically is to put the command into startup-applications, but for some re ...

Super is always pressed down after a mysterious shortcut is pressed

About once every 1-2 months, I accidentally press some mysterious shortcut, possibly from some combination of fn+alt+super keys, where the result is that the super key is constantly applied. E.g. pressing the arrow buttons moves the windows to different spots on the screen, pressing tab brings up the switch between apps menu, and pressing d displays the desktop.

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.
