How to enforce a package dependency instead of an alternative?
cn flag

I am developing a Debian package for Ubuntu which uses Java 17. We have historically had a runtime dependency on openjdk-17-jre. We have a part of our software that has used JavaFX on Windows and macOS for the web browser component. We have disabled this page on Linux since OpenJDK doesn't include JavaFX. I finally figured out how to include openjfx and libopenjfx-jni and then modify our startup script t ...

Headphones "locks" sound
cn flag

I have a Thinkpad X1 running Ubuntu 22.04 and docking station. If I insert a headphone into the jack, the sound will only come out of the headphones... I can't select the speakers on the monitor. My last Thinkpad (running RHEL 8 or 9) and docking station did allow me to leave the headphones in and still switch the sound around.

How can I fix this in Ubuntu?

I'm using Ubuntu 22.04. After I plugged the adapter in I didn't check if the adapter worked and installed drivers for the t2u wireless adapter by mistake. After I did that I think I uninstalled the drivers for the t2u. Still when I plug my t600u plus it still says that I plugged in a t2u adapter. I also managed to get the t600u drivers from the official website, but I don't know how to install it.

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.
