How to install Cuda Toolkit Version 11.1 on Ubuntu 20.04?
in flag

I am trying to install cuda toolkit version 11.1 on Ubuntu 20.04 because a neural network I'm using is only compatible with cuda version 11.1, however, the latest version is 11.3. Is there anyway I can install version 11.1 (Haven't installed cuda yet, nvidia driver: 460.73.01).

Trying to Flash ROM, asked to install "make' and C compiler. Probably not needed
ar flag

I am trying to to Flash Rom on a Lenovo X-230 with Skulls, supposed to be a frequently used, straight forward Process.

I think my problem is the creation of a back up file, and how the CLI command is then re written.

It is Sunday, and I only have a Hotspot connection on my phone, so I don't think I have enough data to install a C Compiler just to test what would happen if I downloaded it.

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.
