Udev rule for USB storage device and partitions
sy flag

I am trying to set up a udev rule which symlinks /dev/sda to /dev/cm, /dev/sda1 to /dev/cm1 and /dev/sda2 to /dev/cm2. Of course, depending on what else is connected to the computer, instead of sda, the device could turn up as sdb or anything else. So I have this rule:

SUBSYSTEMS=="usb", ATTRS{idVendor}=="0a5c", ATTRS{idProduct}=="0001", GROUP="disk", SYMLINK+="cm"

This rule matches my device and  ...

ph flag

I have a hot-corner action assigned for "Present Windows - Current Desktop" (under System Settings > Screen Edges) and it works well. However, the preview can quickly get too chaotic and confusing when you have 10 windows of Firefox, 5 windows of Dolphin and several other windows of different apps open at once.

On macOS, Mission Control solves this problem by grouping windows of the same app i ...

When I'm typing in the bash, something is trying to autocomplete my input in a rather weird way, see picture attached. I'm not pressing tab or something, just trying to type like "describe table" or "select"

What's causing it? How to unmount?

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.
