Imaged a LUKS drive while unenencryted, now can't mount
gb flag

while imaging a LUKS drive I accidentally imaged it while it was unencrypted (only imaged sdx1 instead of whole drive, sdx2 was boot). Now it won't mount. I've tried pretty much all methods to try and mount it but no luck. It can still be unlocked and locked via disk tool or luksOpen command, is this salvageable?

I've tried imaging to a separate drive, losetup, mount, mounting the image,etc. When ...

in flag

I'm running LUbuntu 18.04.5. The filemanager is PCManFM.

Via the GUI of the Gnome 'Disks' accessory, I formatted a (till then) good, working external HDD, a 2TB WD 'My Passport', with the intention of having a clean, uncorrupted external HDD to which I could then attempt to backup my Home folder via the GUI of the Duplicity Deja-Dup ('Backups') accessory.

When I formatted the HDD via the GUI for Dis ...

Removing only-ubiquity / maybe-ubiquity from GRUB boot parameters does not change anything
cn flag

I am customizing the Ubuntu 20.04 live ISO. I want it to boot into the live environment, without launching ubiquity in the contained GNOME desktop environment. I did some research, and I am pretty sure the only-ubiquity and the maybe-ubiquity parameters do that. So I removed them. Then, when I boot, Ubiquity launches. Do I need to edit some other file, or is this parameter not useful anymore? If so, how ...

br flag

I'm new to Ubuntu and Linux in general, and just installed 21.04 on my laptop and set it up to dual boot with Windows 10. When I shut down, either through the GUI or the terminal, the splash screen shows up, disappears, then comes back, frozen, while the fan ramps to full speed. When checking shutdown logs right during shutdown, I see that it reaches "Reached target Power-Off." Right after that, the fan ...

Adobe Acrobat and Master PDF editor both allow users to change the Z order of objects (i.e. determine which object is obscured when objects overlap). However, neither appears to allow the same functionality for link objects (A link object is created by clicking "Insert Link" in Master PDF editor). Links created more recently have the shallowest z value (at front). Some pdf readers will return the shallo ...

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.
