Server supports TLS1.3 but refuses 1.2
my flag

I have the following Problem:
Im hosting my website and some tools on a VServer running Ubuntu 18.04 behind an apache2.
Some people told me that they can't reach my website and I tracked it down with https://www.ssllabs.com/ssltest to being probable that my server supports TLS1.3 but not TLS1.2: SSLLabs Protocol Configuration (screenshot)
Im a bit confused with that, my openssl version tells me:

How to redirect the kickstart output to the serial console?
in flag

I am trying to automate a server build using HP's ILO virtual serial interface to avoid the advanced license.

When the kickstart file is running, none of the output is sent to the serial console.

Including the following in the kickstart file will redirect the installed OS output to serial as desired but only after the kickstart has completed. bootloader --append="console=tty1 console=ttyS0,115200n8 "

Does the OS stop all PIDs before restarted when the user clicks restart in Ubuntu?
in flag

I have a server written in Node.js listening to SIGTERM and SIGINT events. I'm wondering id the Ubuntu stops all PIDs (or which PIDs) it stops before restarting. So for example if my node process listens to those events and wants to gracefully shutdown but gracefully shutting down will take awhile how long do I have before the OS force kills it.

NGINX opensource: ensure communication encrypted between balancer and nodes
tr flag

I'm setting up a load balancer that has to communicate with the other nodes using TLS. This is important since back-end nodes are not in a private network. The configuration is the one below.

The result is that Nginx returns 502 bad gateway, and Nginx seems not able to redirect to my domains. Furthermore, since I'm using open source version, I cannot use the resolve keyword inside upstream configur ...

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.
