google cloud print , "Save to Google Drive" not working
et flag

I no longer have the option to Save to Google Drive in my printer dialog.
I am logged into my google account with Online Accounts. On my account page at google.com, I see that Gnome has access to Google Cloud Print.

Could this have to do with two factor authentication which recently I am 'forced' to use?

No video out and no usb after resuming from suspend
wf flag

I've been having an issue on Ubuntu 20.04 LTS where if I leave my system suspended for more than a couple of days, my monitor may get stuck at no signal when I turn my PC back on. Ctrl+Alt+F(4-6) won't give me a picture back, nor will the first half of the Sysrq REISUB sequence (I've enabled and tested it). Plugging the monitor directly into the motherboard instead of the graphics card also doesn't work ...

Keyboard and mouse not working after dual boot OS switch
cn flag

I have a dual boot setup, Windows 10 and Ubuntu. They are on separate SSDs on my laptop. I hibernate them before switching to another OS. If I do it consecutively, I will have no problems on my boot. But if its a couple of hours between, I am not able to use my keyboard and mouse after boot up on Ubuntu, even my laptop's own keyboard. The touchpad works though.

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.
