Ubuntu 20.04 freezes for exactly 10 seconds during boot, then works normally
in flag

I have a notebook LG Gram 14z980 with Windows 10 by default. I installed Ubuntu 20.04 with dual boot and I notice that the boot time in Windows were much faster than Ubuntu (about 10 seconds). Then, I investigated dmesg and guess what... Ubuntu freezes exactly 10 seconds doing "nothing", then continues booting normally.

Example of dmesg:

First, I want to say that I have decided to make the switch completely to be a Linux user now. So what I am about to say very much well could be a user error issue.

Trying to upgrade Java to the latest version of the Minecraft server (v1.18), I had a bit of a drama because the server was initially running Ubuntu 19.x, so I've converted to 20.04 after finding the place that allows me to update all the packages and do the upgrade.

After this I have installed the JRE, this is the same command showing the version I am up to:

gNote Ignoring Directory Sync After Fresh Reinstallation of Ubuntu
tr flag

According to the good folks over at gnome, the default and only version of gnote available for Ubuntu 20.04 is gnote 3.36.0. And it is too old for them to provide support for, therefore the ubuntu team can address my current gnote issue:

I am using Gnote Version 3.36.0 on Ubuntu 20.04. I have a hybrid SSD/HHD machine with my home folder set as the hhd partition.

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.
