I have a bunch of webp images and need to convert them to png format. I know png supports different color modes like grayscale which I need.

Is there any Linux tool or online services to achieve this fast and easy?

Adding MemTest86 to Grub if boot partition resides on NVME drive
uy flag

I want to add MemTest86 to Ubuntu 20.04 grub menu. I followed Official MemTest86 guide, but they presume that the system EFI partition is on the SATA drive (/dev/sdX). I have NVME drive for the system partitions, so below entry does not work. If I choose 'MemTest86' entry in grub menu it can't find the place. How I should modify /etc/grub.d/40_custom?

Thumbnail view in 'Files' can't see .webp images
us flag

In the ubuntu files browser 'Files' I can set the default viewer for a given filetype (right-click->properties->open with) - but is there a way to get Files itself to show thumbnails for .webp images (which eg imagmagick, cv2 and gimp all seem to handle) ? It does this e.g. for .jpg with no problem.

I have dual booted my computer into Windows and Ubuntu. My SSD is divided into two partitions. One contains the Ubuntu files and the other Windows files. The HDD is my data drive.

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.
