High Load Average in Solaris Operating System - Due to high read I/O

Amazon SES - Domain Verification - Does it expire?
gq flag
Uri

I read the documentation about verifying domains in Amazon SES, and I don't understand - how long does the domain verification last and does it expire?

What happens if I remove the DNS settings after I verified a domain? I tried to do it with the DKIM DNS settings, and there I received a notification that the DKIM of the domain would be revoked, unless I restored them. But with the domain itself, I  ...

ansible: trigger same handler from multiple roles at the end of the playbook
in flag

My ansible playbook includes several roles, for example dovecot, postfix, postgres and rspamd. All of them require SSL certificates, which are generated by the certbot (lets encrypt) role. For this reason and for easier handling all roles follow the same data structure to define SSL certificates with different requirements:

Why is my policy-routing setup not working?
br flag

I have an EC2 machine running Ubuntu 20.04 with 2 ethernet interfaces. They are both connected to the same subnet and both are reachable from the outside. I have created 2 custom route tables, one for each interface and both just containing the route entries for the machine itself, the immediate subnet and a default gateway via the corresponding interface. I can add a rule for all traffic to use either  ...

NextCloud : Can you use encrypted drives / file level encryption?
ru flag

I am evaluating NextCloud for a solution for which I have a requirement that files cannot exist on non encrypted disks or the files themselves cannot be individually read or cached.

I have read a lot about NextCloud's encryption documentation but it does not seem to cover any aspects of whether: (a) if someone gains unauthorised access to the server itself, can the files be read or is it possible ...

Correct order of tasks for WSE 2016 domain migration?
jo flag

Some background:

  • I had a standalone non-WSE 2016 server (SERVER3) that contained a single-domain Active Directory forest (as well as the FSMO roles, of course).
  • I clean-installed a new WSE 2016 server (SERVER2) and ran the WSE Configuration Wizard.
  • I then had two standalone servers, each with its own unique single-domain Active Directory forest.
  • I demoted SERVER2 and removed the Active Directory role

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.
