ph flag

I have a 2 antenna wifi that gets a great signal on windows. On dual boot Ubuntu 20.04, it's very weak, to the point that it starts disconnecting if kept on long enough. Any ideas of what could cause this? I tried setting wifi.powrsave = 2, turning off IPV6, and turning off fast startup on windows and reinstalling Ubuntu.

Edit: I've also tried setting antenna to 1 or 2, that didn't help, and I w ...

changes to scaling_max_freq don't persist after edits
br flag

So I'm trying to pump up my CPU's performance by editing scaling_max_freq in /sys/devices/system/cpu/cpu0/cpufreq but for some odd reason, my changes don't actually go into effect. Instead, this happens. I have intel_pstate set to disable and processor.ignore_ppc set to 1, and my scaling governor set to userspace

My CPU is an Intel Celeron 4205U @ 1.80Ghz, 2 cores

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.
