How to boot from a live USB stick on a Mac

Is it possible to boot from a live USB stick on a Mac?

I created the USB stick using this tutorial, and I have tried a couple of different USB sticks as well as using both iso mode and DD mode in rufus.

Grub seems to be loading properly from the USB stick. I'm asked if I want to boot Ubuntu, Ubuntu with safe graphics, and a couple of other options. When I choose to boot Ubuntu from the menu my machine sh ...

Ubuntu 20.04 doesn't wake up after suspend or restart
kn flag

I just got a new PC and installed Ubuntu on it, which I'm completely new to (literally installed 3 days ago). I just found out that when I try to either restart or suspend the PC it turns into a black screen that doesn't respond.

I found a lot of similar questions like this or this but they seem to only focus on suspend and my problem seems to also be when I restart, so I wasn't sure if they are rel ...

32 GB RAM showing up as 1.3 GB all of a sudden in Ubuntu 20.04.3
us flag

So my laptop screen went blank at a point and I had to manually restart. The laptop has a 32 GB single DIMM installed. But since the restart, the RAM has been showing up as 1.3 GB. memtest86 detected 32 GB and couldn't find any errors in the RAM.

How I realized this is that the laptop had become incredibly slow, with even mouse movements being choppy and laggy, and I found out about the RAM while trying ...

how does one bind mouse button 10 in DCONF when using wayland and xdotool does not work?
in flag

I'm using Ubuntu 21.10 with wayland. xdotool does not work with this setup.

I've trying to use dconf to bind a function to a mouse button (toggle-overview). I can not find anywhere a list of the valid sequences for keys in dconf.

I'm willing to use an xdotool equivalent, but I've yet to see a supported one for Wayland.

I've used xev to tell me it's button 10 that I want to bind, I just don't know how t ...

How to drop raid1 and combine two disks to one
cn flag

Goal

In the remote server, it comes with 2 x 2TB disk with RAID-1, however, I have already filled the disk with data and I would like to remove the RAID-1 scheme and make it ~4TB in single mountpoint (to extend the first disk).

Background

For the original lsblk, it looks like:

NAME        MAJ:MIN RM  SIZE RO TYPE  MOUNTPOINT
nvme0n1     259:0    0  1.8T  0 disk

Problem

I had a working internet connection over ethernet prior to shutting down, but now that I've booted back up I can't connect to my own network, let alone the internet.

I had a very similar network issue (along with a myriad of display issues) on a previous install of Ubuntu 20.04 Desktop (as opposed to server, which I'm on now) that was installed on the same SSD, which is pretty old (boot drive o ...

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.
