Unable to update “Dell Inc. System Firmware”: missing signed bootloader for secure boot: /usr/libexec/Fwupd/efi/- Fwupdx64.efi.signed cannot be found
ni flag

enter image description here

I have a Dell XPS 13 7390 BTX, running Ubuntu 20.04. I've noticed this error when updating my programs, specifically "Dell System Firmware 1.5.1 > 1.9.0".

The closest to a solution I found is from https://github.com/Foxboron/sbctl/issues/10#issuecomment-648442565, recommending:

sbctl sign -s /usr/libexec/fwupd/efi/fwupdx64.efi -o /usr/libexec/fwupd/efi/fwupdx64.efi.signed

I did so and the output was:

How to change webcam resolution
us flag

In zoom-client (from snap) I can choose whether to use HD video or not, and turns out this setting persists when I close Zoom and open Cheese. It makes me think that this setting is global instead of zoom specific. Unfortunately Cheese doesn't have this setting, so that I need to open Zoom just to change this setting.

Screenshot

My question is, can I change webcam resolution without opening Zoom, probably via a  ...

Is it safe to remove snapd and snap-store when using gnome?

snap-store consumes 200MiB memory and 50MiB+ disk I/O (for half a day) in the background, and snap consumes lots of disk space. I haven't used them manually but it seems that they provided gnome and gtk:

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.
