ZFS disk with Postgresql fragmenting quickly with write-heavy application
in flag

I am running a write-heavy application where I am storing my Postgresql on ZFS. Generally, it works well, but I am finding that my ZFS pool is fragmenting heavily. I even created a new ZFS pool and moved the data there using zfs send / recv, in order to defragment the full space and try out some new settings which might limit fragmentation, but to no avail.

I'm not sure what is going on. The appl ...

I have a lot of volumes in Docker that don't have an owner anymore. I'm really curious who keeps creating them, but I cannot figure it out. The volumes are empty inside, so I cannot determine it from their content.

Postfix accepts all incoming mail but drops all outgoing mail
cn flag

We are running a Mailman server and for testing purposes I would like to configure postfix on that server to accept all incoming mail but delete any outgoing mail. How can I do this?

Note: "Postfix stop outgoing delivery but accept all incoming" is similar to what I am asking but rather than holding the outgoing mail I would like it deleted.

Receive mail from Paypal only to [email protected]
jp flag

My postfix server accepts emails for 11 domains. I have [email protected] email accounts on 2 of those domains. I would like to only have Paypal be able to send me emails to these accounts. So if [email protected] sends me an email, I would like postfix to properly send it to /dev/null without it telling [email protected] that his email was properly disposed of.

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.
