What is the Btrfs extended attribute 'm'?
cn flag

I recently found one of my Virtual Machine images with the extended attribute 'm'. I tried to look it up, but I found no information. Is this an undocumented extended attribute?

$ lsattr usb2ubuntu.btrfs.img*
---------------------m usb2ubuntu.btrfs.img

Notice the attribute doesn't exist on the backup file.

How to detect that a C/C++ file is using windows specific stuff
sj flag

Basically I want to test files/libraries/code in general that wont run on Linux by detecting windows specific includes, program calls, dynamically linked libraries at runtime, anything that isn't Linux compatible.
This is to make sure that the resulting program always works under Linux.
I also have to automate this

How do I add my script and desktop file so it's configurable as a preferred application?

I'm trying to set up a URL router script that looks at urls and opens them with a different browser instance (firefox profile in my case) depending on the result of pattern matching performed against the url.

I've made myself a desktop file, and installed it with desktop-file-install (details below). I'd expect that it should be visible in the main menu, and as an option when running cinnamon-set ...

How to set LibreOffice as the default app to open Pages documents
in flag

Since LibreOffice can open and edit Pages documents, I would like to set LibreOffice as the default app to open Pages, Numbers, and Keynote documents. For the sake of this question, I will refer to all of these collectively as .pages documents, since the process will likely be the same for all of these.

The problem is that .pages documents are just renamed .zip files which can be uncompressed and o ...

Deja Dup asking for password multiple times Ubuntu 20.04

I'm hoping this is an easy answer: I'm running Deja Dup (or just 'Backup' in Ubuntu) to try to back my laptop onto an external drive.

It asks me to set a password when I start. I do, and then it starts scanning the hard drive to prepare for the backup. When it reaches the end of the files, it asks for my password again, and then starts scanning through the hard drive again.

I'm assuming it's not rej ...

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.
