Is it possible to grant a "read everything" role in AWS?
ru flag

Is there a default policy that can provide read-only access to all services with AWS? Is there are naming convention for permissions that could be followed such as "Allow" : "Get*" in an IAM policy to achieve this type of result?

I know that AWS provides readonly policies for each service, but considering the frequency that new services are added, I'm wondering if there is an aggregate "read-all" policy  ...

md5sum is the same but gunzip test fails
cn flag

I've automated a process that involves fetching a file from a backup server and them processing it.

Sometimes the processing phase fails and I thought it might be due to the source file being corrupted.

I've found that even when it fails, the md5 of copied file matches the md5 of the file in the backup server. So as an additional sanity check I decided to test the integrity of the .gz file.

Increase disk size on Microsoft Azure
cn flag

I am new in Microsoft Azure. I saw the Azure docs and there's showing that we can only increase the disk size while the virtual machine de-allocate/stopped. But for the production it is not possible to stop my virtual machine. I am using Ubuntu virtual machine. So is there any way to increase disk size on Azure virtual machine without stopping it or on the fly ?

We are running a physical server that is not fully utilized. The task is to move this server to a VM. However, I am not sure how many cores and RAM to allocate to the VM. I know I can scale later, but my boss requires a cost estimate and I need as accurate an estimate as possible.

The server is running SAR, but I'm having a hard time coming up with an accurate estimate based on that.

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.
