Wacom Intuos Tablet uses full vertical space but only a fraction of the horizantal space when lowering sensitivity
in flag

I'm on a widescreen monitor attempting to configure a Wamos drawing tablet with height x width of 9500x15200.

I would expect the monitor to map closely to the tablet, but there is significant vertical compression i.e. drawing a square on the tablet surface results in a rectangle on screen wider than it is tall (by a factor of around 3 or 4). I have experimented with xsetwacom settings and can get the ve ...

How do I troubleshoot nvidia-settings not persisting between sessions?
in flag

I'm running Ubuntu 20.04 and using the nvidia-495 driver.

nvidia-settings simply do not persist between sessions. Specifically resolution but also opengl settings etc.

I have a specific resolution of

viewportin: 1830x1020 viewportout: 1830x1020+45+30 panning: 1830x1020

Without this viewport out my display is "stretched" past visability.

On reboot standard 1920x1080 resolution is applied.

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.
