how to remove the master password for the alpine pine e-mail client?
mx flag

referencing:

https://comp.mail.pine.narkive.com/UcMK4NZG/suppress-master-password-prompt

how is the master password prompt suppressed? If memory serves this is indeed possible. As I recall, the file is "sort of" decrypted and then re-created so that it's no longer encrypted...but I wasn't able to find the instructions.

Wine (Windows Apps Interfacing Software) Installer Wants To Remove Unrelated Apps
nc flag

I need to use a Windows interfacing package on Ubuntu since I want to run Affinity Designer and the latter only runs natively on MacOS and Windows.

Following this procedure (or indeed using the Synaptic package manager) you reach a point where the installer asks permission to REMOVE the following packages and it then lists a long range of other Wine-unrelated applications on my PC:

Kubuntu 20.04 -- USB microSD reader won't mount

I have a microSD (8 GB) that I use for transferring gcode files from my computer to my Ender 3 3D printer. Yesterday, I found I couldn't mount this device (via an unpowered USB hub).

The SD card still reads when directly mounted in the micro-SD socket on the Ender 3, and the card and mini-reader combination mounted and read on my partners Mac (a 2015 iMac with current OS), so I presume this isn' ...

Is there a PDF reader and editor with dark mode and multi-color highlights?
cn flag

The use cases are: A GOOD dark mode (if possible not only inverted colors). Highlights with different colors. Fill some tests (for example in questions where you have to put True or False, add comments or edit some parts of text). I achieve all of this with Adobe Pro but now I'm not in Win anymore, I hear suggestions.

GRUB does not remember root file system location

I wiped my old Ubuntu OS and installed Ubuntu 20.04 LTS (alongside Windows 10) from a USB device to replace it. When I first booted into it after installation, the GRUB menu did not load, but it opened the GRUB CLI instead. I've learned that this is due to GRUB not finding the root file system. I followed this tutorial to configure GRUB from its CLI. Everything went alright and I was able to boot in ...

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.
