How to reinstate separate audio/video playback controls for firefox tabs in Ubuntu Jammy (22.04)
vn flag

In Ubuntu 20.04 LTS if you had two (or more) Firefox tabs which were both playing some audio or video then the Gnome dock(?) UI (the pop-over from clicking on the middle of the top bar, where the date shows) would offer two (or more) separate entries to control those audio sources. The pause key on my keyboard would control whichever source was playing first (and it seemed to remember which one that was ...

System Stuttering due to PNY 32GB USB3.2 Elite flash drive?

Bind mouse movement to keys

How would I go about binding mousing the mouse in a certain direction, to a certain key (w,a,s,d)? Also if possible making it only work in a certain application would be nice. The reason i want to do this is to play BotW in Cemu and i want to use mouse as movement, without effecting other applications.

How do I "Add the installation prefix of "Tolua++" to CMAKE_PREFIX_PATH"?
us flag

I'm trying to create a .deb for a game from its tarball. (https://github.com/Wargus/stratagus)

I believe I've installed its dependencies, but one I'm suspicious of is tolua++, which is a sort of an interface between C and Lua. It seems to be uncertainly maintained: it isn't apt-gettable but it can be downloaded from the Debian packages list, which says the upstream source has been offline since 2020.

How to specify terminal resolution?

  • Desktop with an old Intel CPU (3rd gen I think) that only goes up to 1080p

The issue I'm experiencing is that for some reason, the CLI is configured to run at 4k, but it's outputting at 1080p. The result is what you see in the attached image after running apt upgrade. Image too big for TV.

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.
