I am running Ubuntu 20.04.3. After upgrade to Kernel 5.11.0-27-generic when I reboot the computer, it starts with a black screen and no grub menu appears. If I turn off the computer and then on there is no problem. I checked with previous kernel 5.8.0-63-generic and it didn't have this issue.

Alternative to transfer files via command line (not using SSH)
jp flag

Because of my job I need to connect to a remote server with SSH on which I am connected by vpn and transfer large files in both directions. That has always been easy until I traveled to another continent where I am now, in which I am getting very high ping and very low transfer speed. I thought that it would be much faster simply uploading my filed to the internet and downloading them on the server (and ...

Ubuntu Studio and Midi over Ethernet

Is there a standard, commonly used program for handling Midi over Ethernet included in Ubuntu Studio? If not, any recommendations?

I would like to run VCVRack on a number of computers on my LAN, and have them clocked together and talking to each other. They are pretty old computers, and get bogged down if I throw to much at any one machine individually.

Can a .deb package include sources that are to be compiled by dpkg?
us flag

I have a pkg with some c++ code. Currently I'm compiling some of the c++ code as binary, some as library, and I can ship and deploy it on other platforms.

However, I also have a driver there, which I can't cross compile due to its dependency on the kernel, which makes it so that every kernel might need a different binary.

So, what I want to have is a .deb where I will store the binary under /usr/bin ...

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.
