I have Ubuntu on two partitions. A 30GB partition that is supposed to hold the root, and a 240GB partition that holds the home. Currently, my root is full.

I have realized that making two partitions was a mistake, I should should have put everything together in the 240GB partition, considering that both partitions are SSDs. How can I move everything into one partition without losing my /home data ...

How can I make audio applications use 44.1kHz as the default sample rate, Ubuntu 21.10?
gb flag

Its all change now with pipewire.

I have a USB-attached DAC which shows the current sample rate (but not the bit depth) and I'm currently using Kodi - but it is choosing to access the DAC at 48kHz so it must be resampling my CDs - I want to stop it doing that.

Ideally I'd be happy to access at 32le depth and 44.1kHz.

Constant static through sound card
de flag

I have constant, low-level static coming through the sound card.
It goes away for about a half a second if I kill pulseaudio with pulseaudio -k. It isn't a ground loop, since everything is running through the same outlet and single-point grounded.

I have tried going into the main audio settings and it goes away immediately if I change the input device. But that seems to only happen because whenever ...

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.
