What is the directory "//"?
bf flag

My teacher asked me why directory "//" (double-slash) exists.

I know that the // is the same as /.

I search for it and found many answers (// was created for compatibility with older Unix Systems) and other like (// is nothing and is just the /).

My teacher said that is all wrong.

So why // exists, what is the propose of having a directory that do the same as /?

software for detecting voices on audio recording
ph flag

I record audio for hours on my smartphone for security purposes, personal safety in shared accommodations, and need to prepare evidence but it takes forever to listen to these recordings. VLC really is terrible for this as even the play faster, slower are hidden in the menus. What I want is a player that skips the no-voice or "silent" ie. irrelevant parts of recordings and stops when it detects human ...

Test sounds like "front left", "front right" played on headphones too. But alert sounds played on speakers correctly. The trouble is not in speakers.

How to set DNS on an Ubuntu 18.04 Server (with a broken upgrade)
cn flag

I am in a little bit of a tough situation. I upgraded my Ubuntu server from 16.04 to 18.04 but upgrade didn't go well. Now, it shows version 18.04 LTS on "lsb_release -a", and cannot install any packages because Apache doesn't want to upgrade to the default version on 18.04.

That is a Jira Server (v18.12 to be exact). As far as I understand, I cannot change the Apache version because of that. Now ...

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.
