Scanning software similar to Finereader
cf flag

I'm looking for a tool to scan paper with a scanner, that has more options than Simple Scan. So far, Simple Scan is the best, but it is so lacking in features.

In Finereader you have an option to scan a page automatically, with a timer for the delay while you're flipping the paper. It's a simple concept, but looks like no tool for Linux has this feature. It also has many more features that make the sca ...

cn flag

I installed Xubuntu 20.04 on a 2T SSD drive. To my surprise, it installed the old ext2/ext3 file system instead of ext4. Why is that?

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.1 LTS
Release:    20.04
Codename:   focal

and checking file system showed ext2/ext3:

$ stat -f -c %T /

Why did it not install ext4, since Xubuntu is based on U ...

Graphics Issue Since Update, Kubuntu Plasma, Seems Worse With Greater System Resource Use
es flag

I recently had a big update to my system. Ever since, I've been having issues with my graphics, especially when the machine is under a heavier workload. I have a fast processor and lots of RAM and had no performance issues before the update. I can still work on huge music files, so the issue seems confined to graphics... although once when it got really bad my whole system froze up and I had to force sh ...

sudo apt-get update fails with a temporary failure resolving sources

I cannot update Ubuntu 20.04 since 2/11/2022. I am connected to the internet wirelessly, on a private network at my home. There is no proxy set up. My main OS is Windows 11.

Pinging localhost works the same for the IP that is inside of /etc/resolv.conf

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.
