How to set up DNS settings with a domain in the middle for DKIM and SPF?
us flag

I am working on a tool that helps the users send emails. I plan on using an MTA (Mail Transfer Agent) in the back end like AWS-SES or Sendgrid etc. In order for the emails to arrive successfully in the recipeints inboxes, the users will have to set up DKIM/SPF by configuring the DNS settings of their respective domains.

Now if I take SES for example, I know they have an API that allows me to add an " ...

How can I use a legacy ssh-rsa key on CentOS 9 Stream?
br flag

I am setting up a new CentOS 9 Stream container as a part of a CI system. It needs to make an SSH connection to download some code from a legacy Git host using an ssh-rsa key (which is considered an acceptable risk on this network with this host).

I start by generating a key.

ssh-keygen -t ssh-rsa -f test_rsa_key

Running with the key I get a "no mutual signature algorithm" error.

ssh -v -i test_r ...

http timeout with docker bridge network, but port 80 is opened in firewall
cn flag

I'm trying to install mailcow-dockerized in my server, but I'm having trouble with Docker network. I tried several ways, but I get lots of connection timeouts in containers.

In order to breakdown the issue, I decided to leave Mailcow behind and installed just Docker to try to identify the source of these connection timeouts.

So, I've installed a fresh Ubuntu 20.04 image from my VPS vendor and setup  ...

Windows Network Limited Throughput with Occasional Very Slow Start
cn flag

We have a 1Gbps (up/down) Internet link at work and I noticed performance was terrible when communicating with our servers in the Cloud. By terrible I mean, out of the theorical 1000Mbps, we were getting 30Mbps top. After long diagnostic sessions we came to realize that we have a network performance problem when receiving data from our Windows Server machines. Strangely, we get pretty decent speeds when ...

gcloud compute commands sometimes getting stuck in WSL
in flag

I am running various gcloud compute commands from the linux subsystem on Windows 11 using Debian. In general, it works great. However, sometimes the gcloud command simply does not return, even after several minutes. Sometimes it happens once, sometimes several times in a row. This happens regularly enough that I cannot trust that a sh script that uses gcloud commands will run through to completion. Here ...

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.
