Crash during secure erase in Disks utility and can no longer access drive

I started a secure erase operation in Ubuntu using the disk utility (example below) and the machine locked up, I rebooted it, and now can no longer access the disk. Upon booting, the BIOS asks for the disk password, which I have no idea what it would be. I've tried empty and my linux user password, neither of which work. I suppose my hope is that the Disk utility uses some default password during erase, ...

Multicast packets sent out every time a USB device is connected

On Ubuntu 22.04, every time a USB device is connected to the computer, the system sends IGMP and WS-Discovery packets on the network. More specifically, on a newly installed Ubuntu 22.04, connecting any USB stick or USB mouse will trigger the sending of:

Error configuring broker SSL environment for ActiveMQ 5.17

Hoping this issue has arisen previously and has a simple fix. I have installed ActiveMQ 5.17 pretty seamlessly thanks to the Apache docs.

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.
