Boot Repair - GRUB2 MENU dpkg
cc flag

I am currently running Ubuntu on a 7.5GB flash drive, as my 256GB SSD (partitioned as a Linux system) does not seem to be able to boot. When I do boot it from the BIOS menu, it comes up with a strange GRUB menu that has a black screen. The screen indicates I can hit Tab for a bunch of commands, but none of them seems to be of any help.

This problem occurred because I tried to erase my disk and reinstall  ...

Slow NVMe speed on new install
ca flag

I've just setup an HP z230 Xeon E3 1225 v3 machine with an HP TurboDrive G1, with a Seagate Firecuda NVMe SSD. I was expecting 2-3000MB/s read speeds, but am seeing way less than that. I don't care too much about a few hundred here and there, but I'm seeing 300-400MB/s, which makes me think something is misconfigured.

es flag

On my dev system (Kubuntu 20.04) I just installed CUDA 11.3. After checking the installation, I found some older CUDA packages installed, which are remainders from experiments some time ago. That CUDA 11.2 installation was incomplete, so I needed to remove the packages one-by-one (not via the "cuda" metapackage). I was able remove all of them except one: cuda-cudart-11-2.

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.
