Can I use an existing EFI partition as /boot?
es flag

So I'm planning to switch full-time to Pop_OS! and while backing up (which is another can of worms I'll be explaining later), I realized "Wait, do I have to create a new partition for boot? Or can I use an existing one?" I didn't really know what the answer to that was so I decided, before switching to Pop_OS!, I'm gonna ask here.

Ethtool cannot advertise speed 1000 on 20.04LTS r8168
jp flag

I recently faced an ethernet issue where I was stuck on a "wired connecting" loop, I was able to fix it, but now am unable to use gigabit ethernet. I know that it is supported by the cable and the system, as I was able to use it before and even in output of sudo ethtool enp1s0, it shows

Serious lag in typing after loading Ubuntu 20.04 Lts on older computer
fr flag

So I tried to update an older HP 550-a114 and install Ubuntu 20.04 Lts. Everything seemed fine with the install until I started typing. There is a serious lag between when I type and when it appears on screen. I updated my RAM to 16GB and 1Tb ssd. I thought that this would solve the lag but it didn't. Does anyone have a clue to what may be causing this issue?

Gpick (0.2.6) is not working anymore on my computer (Ubuntu 20.04.3 LTS). When I click on "Pick color", I do not see the display around my mouse in the small box where it should be magnified. This box stays gray. When I pick a color (by pressing the space bar) it is always black (#000000).

Ethernet over USB-C not working when plugged in after boot
cy flag

When my USB-C adapter, which contains a LAN port, is plugged in while the system boots, everything works fine. However, when I boot up the system and plug it in afterwards, the system does not register the LAN connection through the adapter. Everything else on the adapter (USB, Headphone jack, HDMI) is working fine. Any ideas?

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.
