Can you tell how much of it is really necessary for a small website? I don't want to pay 100s for unused rules.

P.S. although the website is small, there is at least one competitor, who is a malicious person and is almost certainly  ...

New Epyc vmware host slow for .net applications
kz flag

We have a EPYC Rome 7502 host running vSphere v7.0.3, and for .net applications we're seeing a performance hit of around 50%, compared to the old host which is Xeon E5-2630.

The performance hit in the .net app is all CPU based.

CPUZ suggests the host should be faster for both single and multithreaded tasks.

According to VMWare's white paper we shouldn't have to do anything. It doesn't explain how to con ...

Forward Email with own address
cn flag

When automatically forwarding emails sent to "A" to another account "B", then B sees the original sender of the mail in the inbox. But I need an automatic forwarding where B sees all mail as if A directly send them to. So the sender needs to be A.

When forwarding a mail by hand, it behaves how I need it. But I need this to happen automatically.

How can I do this in a google workspace account?

Is there a sample gccloud script to migrate a machine from general-purpose to compute-optimised ? Its a webserver so I'd rather the new machine keeps the IP also. Downtime 10-20 min is OK.

Sieve: Filter Rules
in flag

I want to implement a rule as follows:

  • If "To" comprises only addresses having "*@example.com" -> discard
  • Otherwise -> keep

In other words:

  • If "To" comprises at least one address different to "*@example.com" -> keep
  • Otherwise -> discard

The problem with the statement if not header :contains "To" "@example.com" { keep; } else { discard;} is that a mail is not kept if there is a "*@ex ...

How to convert any video to mp4 with php, ffmpeg and CentOS
us flag

I have been converting videos for about a year working in localhost on a Mac. The path is, '/usr/local/bin/ffmpeg' and it has always worked fine. Recently, I installed ffmpeg on my server, with a CentOS 8 operating system, and the php script I have recently used is not working. My question is, 'Where is the path for ffmpeg in CentOS 8?'

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.
