I just booted into Ubuntu and got it turned on on my Raspberry Pi. When I did, it took me through a terminal screen then asked for a username and password in a black terminal looking environment. What is it and how do I get to the setup screen?

In arbitrary line of text, how can bash extract a named value after an equal sign?
ao flag

This question (How to get values after an equal sign) is basically what I want:

Given a line of text, with named parameter looking syntax like color=red, using bash how can you grab that color value (yielding red)?

Except in that question, the line of text is entirely those key-value pairs, so the accepted answer utilizes bash's eval since that syntax happens fit very nicely.


I'm wondering for a gen ...

evince Document Viewer displays at double the actual size
in flag

When I look at a PDF of an A4 paper (or US Letter-sized paper), and set the zoom scale to 100%, the paper on the screen looks twice the actual width (42 cm instead of 21 cm). This happens with all PDF files. On the other hand, if I look at the file at 100% using Adobe Reader on Windows, it displays at the correct size. In both cases, my screen is HD at about 100 dpi. Why is evince wrong? Is there a sett ...

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.
