How do I use a Sony thermal printer (UP-D898DC)?
in flag
MMT

I am trying to install and use a Sony thermal printer on Ubuntu 20.04, specifically the UP-D898DC.

Unfortunately Sony does not support this printer on Linux so there is no driver for Linux.

Do you have any idea how to install this printer on Ubuntu?

USB 2Tbyte disk (EX-RAID 0) not seen
us flag

I try to describe the problem the best I can. I've a 2TB disk initially formatted as a RAID 0 with another HD (that is lost) on another machine not mine. I attached it on an external USB box and I've tried to re-format it with Ubuntu (18.04.5). Sadly it was not auto-mounted, so I've tried some command-line options. I can see the USB device (the HD external box):

Save files on local storage from rclone (OneDrive)
us flag

I have set up rclone for OneDrive. However, I can only access it online. Since I have to work offline quite a bit, I need to access the files offline. In Windows, I can just select that I want to save the files locally. (Meaning they end up in %userprofile%\Onedrive) It will then automatically sync changes from and to the cloud when I'm online.

How do I do this with rclone?

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.
