Please are there any hints on why I am not able to install any R packages? I recently installed the Ubuntu 20.04 LTS OS as well as R and R studio. I am however not able to install any packages in R. I have gone through a seemingly related post such as Cannot install any R packages on Ubuntu 18.04 but the solutions appear not to help in my case. For instance, while trying to install the ggplot2 package, I ...

On i3 wm, gnome-terminal randomly loses transparency and starts showing cursor traces
fr flag

I am using Ubuntu 20.04 with i3. I have reduced my terminals opacity a bit so the wallpaper is a bit visible through it. Sometimes, seemingly randomly (or at least I haven't figured out what is triggering it) it loses its transparency. The cursor also shows faint traces in its previous position as I type, and when its blinking. This goes away when I restart it, and any new terminal I open parallelly is  ...

NetworkManager keeps switching default route between wifi and ethernet

I have two network cards, wifi and ethernet. Both are simultaneously connected to two separate networks. Both networks give me a default gateway.

Now, I want my specific ethernet Networkmanager profile to be prioritized over the wifi-profile all the time. But it keeps switching who is prioritized, causing my ssh connections to die. I can confirm this in ip route and see that suddenly the ethernet profil ...

I downloaded the program Zotero for Linux and it doesn't need installing, only extracting. However, the only way to start the program is by running it from a terminal.

I would really like to have a simple launcher for it. I understood I am supposed to copy a .desktop file from /usr/share/applications/ but there is no file zotero.desktop

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.
