Systemd-networkd and IPv6Token in 20.04

I've been recently playing with IPv6 but I have a vexing problem with my little Ubuntu box. Systemd-networkd (from systemd 245.4) is supposed to understand a directive like this:

IPv6Token=prefixstable:my_prefix

where my_prefix is exactly what my router sends in its RA, 64 bits, ending in a double colon (::), verified by tcpdump. And what I wish to get out of this is an IPv6 address generated as de ...

How to get DHCP from both interfaces in bonding active-backup mode?

How to preserve italic font when exporting Inkscape SVG to EPS on Ubuntu 20.04?

On Ubuntu 20.04, whenever I export an Inkscape (1.2) SVG drawing containing italic text to EPS, the result contains only straight text. I've tried exporting with "Embed fonts" selected, and with "Convert text to paths", but that doesn't make a difference.

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.
