Ethernet RX very slow, TX is fine

Just yesterday I installed Kubuntu 21.04 on my new Thinkpad. I quickly realized the download speed while using ethernet is unbearably slow. Speedtest.net reports <1Mbps down and ~5Mbps up (upload is about right for my internet connection). The download speed is fine on Windows on the same laptop. Wifi also works great.

From what I could find on askubuntu.com, it might have to do with the link  ...

cpufreq scaling governors "ondemand" and "conservative" won't ignore nice load on AMD Ryzen CPUs
fr flag

My kernel 5.11.0-22-generic automatically loads the cpufreq scaling driver acpi-cpufreq and the scaling governor schedutil for my Ryzen 9 5900X. I enabled the setting ignore_nice_load after changing the scaling governor to either ondemand or conservative in order to fit my needs.

Accordingly after the changes everything looks correct; cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor returns

Help installing Ubuntu on external ssd without dual boot

I want to install Ubuntu on an external ssd that is plugged in through usb. I read about a bug that installs the boot on the windows 10 drive and I dont want that. I want to boot into Ubuntu when the external ssd is connected and into Windows when its disconnected. I read about some ways to work around this, but I am not sure which way that will be best.

Thanks, Jimmy

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.
