Sed for replace a substring inside a string with a pattern
in flag

I am trying to replace a part of a pattern, such as, if I have col(3,B,14), after applying the sed command, I would like to get col(3,B,t14) which adds the t character to the third parameter in the pattern.

I am trying with :

s="col(3,B,14)"
echo $s | sed 's/col([0-9],[A-Z],[0-9])/col([0-9],[A-Z],t[0-9])/g'

But, it returns the original string. I would appreciate it if you could give some advice. Thanks ...

MAAS cloud-init hanging due to systemd-resolved?
tr flag

We're observing some weirdness when using MAAS (version 2.8 in this case). The machines get systemd-resolved configured after deployment (using an ansible role) and from that point every system reboot starts making cloud-init hang forever during boot.

We can see on the console that it tries to reach the 10-0-0-0--25.maas-internal FQDN and complains that it can't resolve the hostname, which obviously can ...

Changing the default port without editing /etc/ssh/sshd_config
nl flag

The standard way to change ports, of course, is to edit /etc/ssh/sshd_config. Since I'd really like to avoid messing with the vanilla ubuntu to the greatest extent possible,I'd prefer if it is possible to change the port by putting a Port line in, for example, ~/.ssh/config. I've tried doing this, but to no avail. I've also tried putting a customized copy of sshd_config in that directory, which al ...

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.
