Internal microphone doesn't work after suspend from sleep
ca flag

UPD: updated to 20.10, problem persists.

When I used manjaro, this helped me:

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=auto

or this (I don't remember exactly, but it's almost the same):

options snd-hda-intel model=auto indep_hp=true

For my codec VT1802 (VT18XX), the model is "auto".

I have tried models: laptop-dmic, laptop-amic, inv-dmic.

What command line options for ffmpeg for separate audio and video output to dynamically set devices for streaming
ng flag
  1. Is there an useful way within Ubuntu OS from command line for separation of video and audio for streaming. For video being streamed to a network port (client media player connecting through udp://, tcp://, http://) and audio being redirected to varying (local) hardware devices (listed by aplay -l)?
    (If served with one input for ffmpeg all video and audio streams should start synchronized, AFAIK.)

Compose key combination to enter the minus (U2212) character
cn flag

The minus character − is unicode 2212 and can be entered as Ctrl+Shift+U 2212Enter.

Is there a combination to enter that character with the Compose key? It is also not readily available in the US international keyboard layout, afaik.

I know Compose --. allows to enter the very similar en-dash. en-dash and minus, however, are not the same (–−):

1 + 2 = 3 ; 3 − 2 = 1; 3 – 2 = 1

password displayed on loggin screen but not on purpose
cn flag

I'm under ubuntu 18.04.1 and I face this issue: sometimes, not always, when I loggin back, my password is displayed. I wonder why this happens.

I know that this "password revealation feature" is enabled only when I type my password. I find this quite dangerous as anybody looking at my screen when I type can read my password.

I know that you can display it by right clicking on the password field and  ...

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.
