I recently upgraded from 21.04 to 21.10 and my wifi (which used to work perfectly) now randomly drops until I cycle the networking off / on again from the menubar icon.

I was recently able to observe the precise moment when this happened.

sudo journalctl -b 0 -u NetworkManager identified the following event:

Ubuntu 20.04, I did

$ 7za x .

In the directory I wanted to extract these split compressed files, i.e. filename.zip.00, filename.zip.01 etc.

I'm not sure if it completed, and when I try to run the same command again I was hoping it would either overwrite or use some checkpoint to resume. But it just says: "Scanning the drive for archives" and just stays that way for an hour, nothing changing on the screen ...

Chromium print dialog shows boxes instead of fonts

When I attempt to save an email as a pdf in Chromium, using the print dialog, I get a screen full of boxes instead of font characters when the system "save as" dialog appears. The dialog does not function at all to actually save anything, but does go away when you hit the cancel key or the place on the dialog where cancel should be. This behavior happens in any file save dialog in Chromium, such as rig ...

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.
