multiple prints on epson
ng flag

I use ubuntu 22.04 and an Epson printer (WF7720). Unfortunately, Epson doesn't offer any specific drivers, but most of the commands work. However, since I updated from 20.04 to ubuntu 22.04, I can only print 1 copy at a time - no matter what I set. Under 20.04 this was at least possible if you created a separate print job for each copy. But now even setting the hook in this checkbox will only create one ...

How do I switch Ubuntu 22.10 to Wayland and use the NVIDIA PRIME RENDER OFFLOAD with Xwayland?
in flag

I'm looking for a good tutorial to learn how to switch Ubuntu 22.10 to Wayland and then use the NVIDIA PRIME RENDER OFFLOAD with Xwayland. On the internet there are a lot of sources, but due to the fact that it just didn't work until some time ago, a lot of them are only a wasting of time. So, if someone has been able to do that, can you share the method that worked? thanks.

Transmission : Change Finished Downloads Colour
us flag

I have Ubuntu 22.04. Transmission works fine for me with torrents. But the same colour for active and finished downloads is a bit confusing.

From Google search, I see a few requests on the same on official channels, unattended.

Wondering whether it is possible to do it ourselves somehow. As in changing the downloaded torrent progress bar colour to green.

Any help will be great. Thanks.

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.
