Why is "x86/split lock detection" spamming my syslog when Steam is running?
pl flag

I have a ThinkPad X1C9 laptop connected to 3 displays via thunderbolt and an nVidia 1050Ti in an external GPU enclosure. My syslog is getting spammed with the following, why?

Googling CJobMgr led me to Steam. Closed Steam and it stopped. If I open Steam again it starts happening immediately.

USB stick: medium not found
cn flag

Trying to flash a USB with a bootable OS.

lsblk does not detect the disk. ls /dev/disk/by-id/ reveals the disk lives at /dev/disk/by-id/usb-NAND_USB2DISK-0:0.

sudo fdisk /dev/disk/by-id/usb-NAND_USB2DISK-0\:0

and

sudo fsck /dev/disk/by-id/usb-NAND_USB2DISK-0\:0

each fail with: No medium found while trying to open /dev/sda

What concept am I missing?

On MacOS, if you press cmd + backspace, the whole line gets deleted. I know you can do this in bash on Ubuntu by pressing ctrl + K, but would like to do this in other applications as well. Is there a way to do this?

Every time computer "suspends" (either after the time i chose, by clicking manually on "suspend" or by doing it in terminal) it goes on suspend mode for 1 second and immediately "wakes up".

How To Translate UDP Source Port Numbers Using Iptables

I have an UDP application which sends packets with inbound source port numbers equal to the destination port numbers from both sides of the communication. The documentation also states that this application will not work in case Network Address Port Translation (NAPT) is involved. I have verified that this is indeed the case, and also that a NAT, preserving destination AND SOURCE port numbers works cor ...

"Allow different sources for each windows" does not work for writing notes in Evince
cn flag

With "Allow different sources for each windows", different Input Sources for different windows are saved so you do not have to switch the input source manually for specific windows. But even when you have set up Input Source A in Evince, this is not saved for writing comments within Evince.

I could circumvent this problem by prioritizing Input Source A in the general settings. It seems that for w ...

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.
