Cloudron Open Port 5080
pl flag

I'm attempting to run Antemedia on a Server which is pre-installed with Cloudron. It appears Cloudron's Firewall system has blocked port 5080 by default. There doesn't appear to be an option to open this port inside Cloudron. Does anyone have an idea how I can open port 5080 so I can access the Antmedia Application as this runs on port 5080?

Nginx run as apache user: how to fix owner of tmp folder
us flag

I used to set up Nginx as frontend and Apache as backend, and for the sake of simplicity used to set Nginx to run as apache user (by specifing user apache; in nginx.conf).

After that, default Nginx's tmp dir (e.g. /var/lib/nginx/tmp) become unusable by nginx as it belongs to nginx not apache. Ok, I do chown -R apache ... and fix it - but after a while (looks like until next Nginx update) the ownder of the ...

Can an AWS Application Load Balancer mark a service as unhealthy "early"
mx flag

I try to find out, if it is possible to configure an AWS Application Load Balancer in a way, that if the backend service responds with an error status code (e.G. 503 Service Unavailable) to a regular incoming http request, that the Application Load Balancer then marks the requested backend service as "unhealthy"? Maybe even tries a different one?

I am aware of the typical health checks that AWS Applicat ...

How to make Linux discover new LUNs from Pure Storage FlashArray//X70 R3?
it flag

When a new LUNs are presented to Fibre Channel SAN from a Pure Storage FlashArray//X70 R3, Linux (SLES) does not find those (as opposed to other FC storage systems like the HP EVA or 3PAR StorServ). Even after a rescan-scsi-bus.sh the new LUNs are not detected by the Linux kernel.

The only two methods that are known to work are:

  1. Reboot the machine after the LUN mappings have changed.

On AWS, how do you set a billing alarm if you pay with credits?

Our company has a large amount of credits with which we pay our AWS bills, but I would still like to monitor the costs.

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.
