Postfix: Delete specific emails
in flag

I'm using Postfix as an email relay between a windows app that can't authenticate with gmail and gmail.

Every night between 12 and 1am this windows app sends a superfluous email that ideally I'd nuke before it gets sent.

Is there a way to do this?

Thanks!

We need docker images to use them as test databases, but not able to find any.

If any install steps for linux, we could have used that for creating dockerfile and an image from that but I didn't find any.

In the official site of these products, they are providing direct ova files(virtual machines). Is there any process a ...

Cannot access gitlab web UI after upgrading omnibus to 14.12
in flag

I have gitlab omnibus install on a linux debian server. Yesterday, the installation was upgraded to 14.12 (from 14.11) - and now I'm unable to access the web UI. On investigation, it seems that the issue was caused by a conflict of versions of ruby and passenger. I'm using an external nginx on the server, as the tail server has other virtual hosts. I have the latest version of passenger installed - 6. ...

Is it redundant to add an extra checksum or CRC in TCP packets to make it possible for the receiver verify whether the data is same with the sent one?
cn flag

As TCP contains a checksum and the TCP/IP stack will detect broken packets, is it redundant to add an extra checksum or CRC in TCP packets to make it possible for the receiver verify whether the data is same with the sent one?

Some thought about this question:

1.It's very common seen that there is a sha256 value to verify the consistency when downloading files from internet.

2.The checksum contai ...

Wordpress Slowness Behind GCP HTTP Load Balancer

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.
