id flag

I have installed LibreOffice 7.2.2 on Ubuntu 21.10. Calc is now performing very slow. Just changing the cursor from one cell to another takes up to 5 seconds.

One proposed solution is opening LibreOffice with the terminal command SAL_USE_VCLPLUGIN=gen libreoffice.

If I do so, Calc looks even better and the performance is all right.

Windows does not boot

This is an Ubuntu forum but this problem comes alongside it.

When I start up my computer, it does automatically go into Ubuntu despite having a dual-boot system.

When running GPARTED, it shows that the Windows partition is installed.GPARTED

Earlier GRUB showed the two OS available.

Should I guess is it a problem related to GRUB ?

Any help ?

Thanks in advance !!

Copying files from Windows to Ubuntu via USB gives permissions or rights issues

Copying from Windows 10 -> Ubuntu LTS 20.04

I want to use USB because the Ubuntu box is to be secure and not access any resources on the LAN nor have any online accounts.

I am running bitlocker on my Windows PC. I'm not sure if that's relevant. When I copy files I run into two different problems, say with a simple text file:

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.
