I'm using the Mercure hub 0.13, everything works fine on my development machine, but on my test server the hub keeps on trying to bind on port 80, resulting in a error, as nginx is already running on port 80.

run: loading initial config: loading new config: http app module: start: tcp: listening on :80: listen tcp :80: bind: address already in use

I'm starting the hub with the following command:

Default timeout for server commands - NFS mount
ug flag

Noticed the following: if a NFS mount becomes unavailable for whatever reason, most linux commands will wait endlessly.

Doing an ls -lahF on the mount path just waits... forever. And never returns.

I could run everything with a timeout 5 in front of it, but that feels hamfisted.

Especially when one trusts services either run, or generate an error log that can be picked up, this behavior is danger ...

Disable system property logging in Jmeter

Linux: How to allow outbound rules for seccurity updates
in flag

We use aws ec2 instances with the 'AWS Linux AMI 2' image.

We have a script for security updates with this code: yum update -y --security.

I want to allow only security update in outbound rules - aws security group. Can someone tell me what is the port + ip? if it has a specific IP... I think the port is HTTP 80 since it works after I add it.

My Problem is:

I have a server with an internal domain name service.internal.example.com which redirects all clients asking for another domain to its FQDN https://service.internal.example.com. This server is not under my control and must continue to be reachable as service.internal.example.com.

My job is to setup a proxy that makes this service reachable from the completely separated external.example.com ...

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.
