i7-8700 & 20.04 - PassMark is way below "average" - 10300 vs 13300 median
de flag

I recently moved some edge/IoT machines from an i5-10500T platform to an i7-8700 platform. Immediately after deploying some of the first machines I could just "feel" that they were slower, but couldn't determine why. After A LOT of PassMark testing I couldn't get anywhere about 10,800 on the i7-8700, where the median score on cpubenchmark is 13300+.

So, for comparison, I wondered what the "old" ...

MediaTek MT7921 Bluetooth not detected
cn flag

I bought an Asus Vivobook F513 laptop which has the MediaTek MT7921 Lan Card.

As soon as I installed Ubuntu 20.04LTS to dual boot with windows, I noticed I didn't had either Wi-Fi or Bluetooth.

After a lot of debugging and googling, I found my kernel version was 5.11, and apparently support to my chipset was only added after version 5.12.

As soon as I updated the kernel with these instructions and ...

Help on booting ubuntu?
us flag

I was trying to copy an old SSD to a new SSD and used "dd" to copy over, but I decided to stick to the old SSD and when I booted it didn't boot but I saw the grub console. At that time if I select prefix and root manually following this example it worked just fine.

But I wanted to fix the root cause of this problem and so I used Gparted and I am sorry I can't remember what exactly I had done.

Does Libinput require X/Wayland?
in flag

In short: Is X.org a dependency of Libinput?

Rephrased, can libinput work standalone?

The question is mostly about hacking around with some input devices. I'm trying to route USB/PS1/Bluetooth input through a headless raspberry pi. I want this to be as generic as possible, while keeping my installation as minimal as possible.

nautilus can't delete file on NFS server

I have a mount to NFS share. If I use a terminal and rm the file (with my user) it works with no issue. I am able to delete files. However if I try to use Nautilus to navigate to the DIR and delete the file it wont work. If I right click on the file the delete option is grayed out. If it was a permission issue how would I be able to delete the file from the terminal?

If Windows 10 and Ubuntu are installed on different physical drives, reinstalling a fresh Windows 10 will not have any effect on my dual boot?
mx flag

I have Windows 10 on my SSD, and Ubuntu resides on my HDD. My intuitive thought is that reinstalling a fresh Windows 10 will only wipe the SSD. Am I safe to go ahead and reinstall?

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.
