Why do we need Wayland (or X)?
in flag

I'm not sure why we need Wayland (or X) at all. Since under wayland applications will be drawing themselves then what is the point of wayland? Applications can draw their own windows and widgets, can't they?

What is it that we can't do without Wayland (or X)?

Ubuntu failure to start up

I'm not going to be able to provide all the information you will need to sort out my specific problem, but I wanted some general advice on what to do when Ubuntu won't load (for future issues). Suffice to say I'm in no way a computer pro, I just want to use Linux because I don't want to be tied to any commercial outfit for computing and I have been very pleasantly surprised by how easy it is to do every ...

But when I run this script by doing ./notify-me.sh and pressing the Enter key, the command prompt just skips to the next line and does nothing. It just stays on the empty line until I press Ctrl+C to break the process.

Anyone happen to know if with 21.04 AD integration, tighter integration with Certificate Services is being considered?
gf flag

As an admin in a mixed environment, the biggest bane of my existence it trying to issue internal certs. Right now the only option is using NDES/SCEP, but Microsoft apparently has no interest in supporting that since it can't support their CNG certificate providers, which means the only certificates I can issue to linux machines via NDES/SCEP is ones using older cryptography. Not to mention that setting  ...

pl flag

My Lenovo Legion laptop has Ubuntu 20.04 on it. My initial problem was that, when I boot up the laptop after it goes to sleep, the screen will remain black and I have to reboot to log in again.

I saw one of the solutions was to remove gdm3, so I ran the command:

apt remove gdm3

and rebooted.

Now the laptop freezes at the welcomie screen that is shown after you fire up the device.

So I just pulled an old iPod Nano 4th gen out of my drawer and tried to sync it up with rhythmbox. I received an error but was able to fix it with

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.
