Install ubuntu on mac with no OS
ca flag

I have a mid-2009 MacBook Pro with no OS and I would like to install Ubuntu on.

It is stuck with a flashing question mark folder.

Is there a way I can install Ubuntu using a USB on this Mac? Note that I can't get past this question mark, I've tried most things in the support site. I cannot find a source that aims on how to install Ubuntu with this condition.

Lenovo Ideapad Touchpad not Moving
us flag

I recently get a Lenovo Ideapad Gaming 3 and install Ubuntu 20.04.2 on it. The kernel version is 5.8.0-43-generic. My issue is that I can click using the touchpad but I can't move the cursor with it.

The driver is able to detect the touchpad as it appears running xinput --list but I am somehow unable to move the cursor with it.

I thought this may happens because of the sensitivity of the trackpad but I  ...

Nvidia Drivers updated to 20.04.2 while I'm running 20.04.1 LTS
us flag

I ran sudo apt-get update and sudo apt-get upgrade and it installed nvidia drivers for Ubuntu 20.04.2 while I was running Kubuntu 20.04.1 LTS.

Now I cannot boot into my OS, even in recovery mode.

I've tried changing boot modes in BIOS and not booting in secure mode (On my Asus motherboard the secure boot mode is "setup" for some reason).

Has anyone found a solution to this?

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.
