Ubuntu Bluetooth Keyboard autoconnect

I am an Ubuntu Newbie. My Laptop was running Windows 8.1 for the longest time and I switched to Ubuntu 20.04. Since my keyboard is damaged because of water spill, I've been using a Bluetooth keyboard, namely, the Logitech K480. My hardware has a few other problems as well

The Wi-Fi and Bluetooth adaptors are damaged, and so I rely on USB Bluetooth and Wi-Fi adaptors.

The battery is recognized and will discharge power when unplugged, but later, in order to recharge (when the laptop is plugged back in) the battery must first be removed (disconnected) from the laptop and then reinstalled. Once reconnected, the battery will charge normally.

Any ideas?

Mount USB floppy drive always at same mount point
us flag

I'd like to mount my USB floppy at the same mount point regardless of the disk.

The problem is that adding a line to /etc/fstab with the UUID doesn't work. I thought the UUID belonged to the USB floppy drive, but, apparently, it changes with each floppy disk.

Every time I put a floppy in, it mounts it at /media/whatever-UIID, but I want it to always mount at /media/floppy, regardless of the disk.

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.
