Evolution doesn't work after copying system to a new disk - not connecting, seems to be a password issue
in flag

I use Evolution 3.36.5-0ubuntu1 in Kubuntu 20.04 to do my mail traffic. It worked all fine besides of some irritating asking for passwords sometimes. I deactivated the KDE password manager kde wallet and it was better then.

After migrating to a new harddisk, Evolution asked for keyring password at least ten times, then it worked properly for 2 days. Now it won't connect anymore. I suppose it's so ...

What are the issues that may be encountered in created vagrant boxes if I don't use the default virtualbox ip ranges for machines
rs flag

I am working on Vagrant on my Ubuntu (20.04) and I learnt that the ip range allowed by default is 192.168.56.0/21 and that I can of course remove this restriction and use my own range.

I am new to vagrant and know if they are any inherent or severe results to use the /etc/vbox/networks.conf to set my own ip range. I am looking at using the ranges:

- 192.168.0.0/16
- 10.0.0.0/8
- 2001::/64

I'm checking with the developers tools, and with VP9 on youtube, I get Vpx decode, but with H264, I get FFMpeg only.

I'm launching with the flags:

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.
