Wifi frequently stops working: replace hardware?
bt flag

My wifi has worked for years but recently it's been very patchy; often showing connected no internet; high packet loss between it and the router. Turning it off and on again seems to help most the time, but it's happening more frequently.

I'm not sure if it's likely to be to do with a change in kernel (I'm on Ubuntu 20.04, 5.4.0-91-generic #102-Ubuntu SMP) or a hardware failure. Do wifi cards just get o ...

Zerotier and printer
cn flag

I have a private Zerotier SD-WAN (10.99.99.0/24). Some of my clients also use a local net 192.168.0.0/24. And there is also a network printer with 192.168.0.101.

Since Zerotier does not have a client for this printer my question is: How can I make this printer available in the Zerotier network (10.99.99.0/24). So that I can use it from all my Zerotier clients.

Here is the network config of such a cl ...

My laptop's built-in speakers aren't working (can't select it as sound output device) in a brand new install of Xubuntu 21.10.

  • In pavucontrol (pulseaudio Volume Control) output devices, only "Dummy Output" is displayed.

  • pacmd list-sinks lists only "Dummy Output" sink available:

    properties:
        device.description = "Dummy Output"
        device.class = "abstract"
        device.icon_name = "audio-card"

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.
