I have opened both port 3389 for RDP connection, and 5901 for VNC connection. If I connect through RDP, with Microsoft Remote Desktop, everything works fine, except an extreme lag, which I don't think is due to the EC2 instance, as I a ...

My first thought was it could be a WiFi issue, but ...

Accidentally "repaired GRUB" with boot-repair, how to undo the repair/reinstall backup?
io flag

I accidentally clicked "repair GRUB", now my keyboard doesn't work until after the boot sequence.

I'm fairly certain there was a backup made (didn't change any of the settings, and new files were created), but I can't find the right instructions for what I need to do.

How do I restore the backup made by boot-repair?

None of the audio devices (input and output) are showing up
cn flag

I made some changes in alsamixer after that list of input and output devices were empty in settings. I tried rebooting and re-installing alsamixer but none the methods worked for me. Earlier I was able to see something like digit-analog and s/pdif along with my speakers but now the list in empty.

I tried using alsactl restore and alsactl store but nothing happened.

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.
