I have (for testing purposes using a USB-attached drive) setup a ZFS pool that I would like to share via NFS to one client.

When loading a web page, javascripts are executed to provide info. I want to "load" a page (including executing the javascripts), but instead of getting the html output after that, I want to get the output of one of the executed javascripts. I have the path to the webpage and the script.

Unplugging headphones redirects sound to dummy output. Plugging headphones back in requires manual switch
jp flag

I unplug and plug headphones multiple times a day.

Every time I plug headphones in I need to go to the sound settings where "Dummy output" is selected and pick "Headphones Build-in Audio". Dummy output then disappears. This is very annoying.

When I unplug headphones a dummy output is created and selected, which is perhaps expected if no other output device exists.

How do I empty logfiles in Ubuntu?
lk flag

How do I empty logfiles in Ubuntu? I got message that root has less than 1 GB of space left.. I found out that logfile is huge, over 400 GB. (Does size of logfiles relate to root directory at all?) I'm using Focal Fossa.

I'm unsure to use commands from older posts since I'm afraid they've been changed and I might empty something else in progress.

Grub not booting unless I click esc to open console mode
cn flag

My system has weird issue: when I try to boot normally I just get black screen, but if I click escape when booting to open grub console then it's fine (and I have to switch from grub console to normal mode by typing "normal", clicking enter and then escape again)

Any ideas :)?

Thanks

How do I give a user permission to access external drives?

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.
