Why doesn't my trackpad \ touchpad work on my USB boot of Ubuntu?

I created a bootable flash drive to run Ubuntu on as I have a pretty old laptop with an extremely small hard drive. I had now problems getting it to boot up, but my trackpad (mouse) isn't operational. An ideas or advice would be greatly appreciated. I am going to buy a wireless mouse and see if that makes a difference. I can only assume it is the drivers, but I can't navigate too much on Ubuntu with onl ...

Problem with DNS resolution when NOT connected to VPN Ubuntu 20.04

When I try to access a website it doesn't work anymore and just tells me "DNS_PROBE_POSSIBLE" unless I am connected to a VPN (Proton VPN) then the internet works fine.

After some digging around I am pretty sure it is a DNS issue but I cannot understand how to fix it.

Tried to Dual Boot Windows 11 and Ubuntu 21.04

I was originally trying to install Ubuntu on a USB drive, but then I decided just to dual-boot it. Ubuntu told me to disable Intel RST, so I followed the steps in this guide until I got to the commands.

Basically, none of the commands work other than listing volumes and selecting volumes. It doesn't detect the C:\ drive as a Windows boot drive. At this point in time, I have no installation of Ubunt ...

This has been happening for the past couple days. When the display shuts off, it doesn't come back on when I move the mouse or hit something on the keyboard. The monitor wakes up for a second and flashes "no input" before shutting off again. I know the OS is still active because if I press Ctrl+alt+F2, I can get to the terminal. From there, I can do ctrl+alt+F7 and it brings me back to the GUI. Does any ...

How to make all cron jobs output to syslog?

I can configure individual cron jobs to output to syslog by making them explicitly pipe their output there, with e.g. | /usr/bin/logger -t MYJOB. Is there any way to make all cron jobs output to syslog by default?

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.
