Ubuntu Server 20.04.3 LTS - Can I easily connect to a new wired network like I could during setup?
gb flag

During the installation of Ubuntu Server, my wired network is automatically detected and connected. This is super convenient for first-time setup, so is there a way to re-run that automatic detection later on, if I were to move my server to a different network?

Everything I found elsewhere guided me through a long and tedious process of manually adding or editing the network configuration, when,  ...

Permanently setting intel pstate driver to "passive"
cn flag

My i5-11600K CPU is using the intel_pstate frequency scaling.

By default, the driver is in "active" mode and will throttle up ALL 6 physical cores, even if there is only work for one core.

To fix this, I do:

# echo "passive" >  /sys/devices/system/cpu/intel_pstate/status

But after a reboot, that setting is gone again.

How can I permanently set intel_pstate mode to passive?

screen brightness suddenly dimmed and now won't go above 50%

I was just working on my computer doing nothing particularly interesting and my brightness suddenly dimmed and won't go back up above 50%. I can control the slider and I tried manually adjusting with echo x | sudo tee /sys/class/backlight/intel_backlight/brightness but anything above 5000 or the halfway point on the slider just doesn't get any brighter. Restarting doesn't do anything either. It could ...

System randomly reboots, syslog shows "@^" repeatedly before the crash
de flag

I've been using Ubuntu on a new laptop for a while now (Lenovo Legion 5, Ryzen 5000 7, RTX 3050), and I've been plagued by a random rebooting issue. There's no pattern to when it happens or what I'm doing when it happens. Sometimes it'll be fine for a whole month, sometimes it happens multiple times per day. It happened just a few minutes ago, and the last thing few things in my syslog are:

I am trying to mount a previous Ubuntu 20.04 boot drive (250GB M.2 NVMe SSD in a USB-C adapter) to a Ubuntu 20.04 machine at /mnt/foo.

Lenovo Ideapad is never charged to 100%, and the charger cannot be detected immediately

I installed Ubuntu 18.04 onto my Lenovo Ideapad 3. When I plug in the charge, the laptop cannot detect the charger and get charged right away, it will however detect it and start the process 30 seconds later. Same goes to unplugging the charger, it cannot detect the unplug of the charger until 30 seconds later.

The other thing is the power can never go exceeds 98%.

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.
