Repair USB drive (read only)

I have read the forum for possible solutions, but I haven't found one that works for me yet. Here is the issue. I was copying files from my SSD to my USB drive, and I removed the pendrive!; it was dumb, but I did it. Now the pendrive is "read only" (and I can't mount it) and I don't know hot to fix it. I have tried with Disks, Gparted, with the terminal, and no luck so far. Any ideas will be appreciated ...

After upgrading to Ubuntu 22.04, WiFi has stopped working completely. Even after installing the driver, it doesn't connect to any available network

I was using Ubuntu 20.04 LTS (which I had upgraded from 18.04 LTS). I upgraded to 22.04.1LTS. After the upgrade, the WiFi driver was missing (typical Ubuntu upgrade). In 20.04 I used to fix this issue using a GitHub repo lwfinger/rtlwifi_new, which is now missing.

So after a lot of searching and trying to find the correct solution, I implemented this.

LXC host losing internet access when bridging lxdbr0 with ens3

My LXC host loses access to the internet when bridging an interface between lxdbr0 and ens3. LXC guests also fail to access WAN when the bridging is effective.

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.
