OnePlus Bullets Wireless Z Bass Edition Mic not working in Ubuntu 20.04
ne flag

I am unable to switch to HSP/HFP mode, it works only in A2DP (only speaker works). And i have already tried this solution and it got mic working, but when i selected HSP/HFP, i got too much noise in speaker (A2DP Sink gives clear sound).

It works fine on windows 10 (Same PC) and my android phone. And i checked on OnePlus site, and i can't find whether it supports HSP/HFP or not.

Visual artifacts in x2go XFCE4 sessions after upgrade from 20.04 to 21.04
sh flag

folks.

I've been using x2go XFCE4 sessions on a box for ages with no problems but after an upgrade to 21.04 (from 20.04) I'm now getting strange visual artifacts: black boxes around windows, ghosting, etc. (See screenshot below.)

If I login to the box regularly -- meaning not via x2go -- everything is fine.

Anybody have any ideas as to what might be happening?

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.
