How to completely disable 3 finger tap by any means in libinput

What I want is to be able to just disable 3 finger tap because I never use it and it also messes up what code I write. I use libinput and synclient is not an option. I also use X11 instead of Wayland. My goal is to completely disable it. I have been searching for 2 hours now, so finding a duplicate to my question is hard.

System freezes when RAM limit reached, doesn't use swap
ru flag

I have a 16GB RAM system and whenever I hit the limit of RAM the whole system freezes even the mouse cursor starts to become jittery until it doesn't move at all. Keyboard, mouse, nothing. So I am forced to do a hard power-off which isn't probably good for the electronics. I've set up a 16GB swap which shows up properly in free -m and in top but it's always at 0 usage.

What should I wipe on my /home mount after a fresh installation?
in flag

I keep my system as followed:

  1. Ubuntu installation (mount point "/" and EFI boot) is on a NVMe SSD disk.
  2. All personal files (mount point "/home") is on a different SSD.

Every now and then, I would wipe the OS on the first SSD and remount the "/home" point from the second SSD so I can keep my personal files untouched between each installations.

However, there are many hidden folders in "/home", such as ...

I have deleted the windows on it and replaced it with ubuntu, bu ...

Does Ubuntu 20.04 support the Lenovo ST50 with the Raid-530 8i adapter

Has anyone made a Lenovo ST50 run with the Lenovo Raid 530-8i adapter ? We have tried setting this up with no luck. We fall back on the onboard software raid for the time being but i'm interested to know that could get this to work. I found out that the ST50 is supported but it's unclear if the Raid adapter in the ST50 is. The RAID adapter is supported on other Lenovo servers 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.
