Why alsa apps freeze pulseaudio?
cn flag

On Ubuntu 18.04 LTS (or 16.04? I do not remember because it was a long time ago), running alsa apps was freezing any sound in Chrome and other apps which used pulseaudio. jackd was silent with pulseaudio, when switched to alsa worked, but pulseaudio apps worked no more. I am not sure if stopping jack was bringing pulseaudio back, possibly. The card was old and I though that it might be its drivers ...

I tried changing it with all the methods I could find on the internet (sudo passwd root, passwd, selecting “root” from the menu at the beginning, etc) but none of the worked because every time I try using a sudo command, it asks for a password ...

How can I see the “console” on my VirtualBox install of 20.04?

I used to see all the system messages, etc. when I booted up my 20.04 VM. I still see all of that, but after it’s finished, instead of seeing the login prompt I now have a GUI with a login prompt. Is there a way to get rid of this?

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.
