My laptop (Dell XPS 13, 9350) has a single USB-C port, which I am used to connecting to a docking station which is in turn connected to peripherals (USB devices, audio, display, power supply).

Suitable keyboard for laptop
us flag

Just installed Xubuntu on a laptop, and have an issue with numlock on boot up. There is no numlock settings in the bios, and on boot, the numpad in the middle of the keyboard is on. Have just the usual English international at the moment. Is it possible to select a different keyboard type, that will work with a laptop - specifically, will startup without numlock?? Thanks.

/usr/bin/snap disappeared suddenly

I had some applications installed via snap that were running perfectly until today.

When I started my computer I was not able to launch them.

These applications still show on my apps list but clicking on one doesn't launch it.

Also trying to start them via terminal results in a command not found error, even thought my shell suggests the command.

Another thing is that the applications still exist in

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.
