The machine won't wake after suspend.

This happens both when I close the lid, or when I suspend from the power off menu.

However, pressing buttons on the keyboard (even the built-in) or moving the mouse / touching the trackpad does not wake it up.

Ubuntu OS download consistently stuck at 0b/s
tt flag

The download will start off strong (2.0mb/s or so, probably a server limit) and then quickly drop to 0b/s or something slow like 32kb/s. Then eventually the download will say something like: "unable to download" or text similar to that. Once I resume the download, it picks up speed and then plummets again.

In the Transmission application, I assumed you select a torrent and then select PropertiesOptions and there exists a Ratio option.

Is it possible to install a previous version of a package with apt?

Initially on my Ubuntu, I had bash 5.1 but to use bashdb I needed to get a previous version : bash 5.0

To get bash 5.0, I've been to the official website of bash and downloaded the version 5.0 manually since apt would have installed the latest version of bash : version 5.1 that I don't want.

Then I built bash 5.0 myself with make.

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.
