How to load new Apache site without effecting existing sites?
in flag

If I add a new Apache site at /etc/apache2/sites-enabled/newsite.conf, how to I load that new configuration without bringing down any other sites currently being hosted by Apache?

As far as I know, sudo apachectl graceful and sudo service apache2 restart and sudo service apache2 reload all cause a brief outage to all sites, with the outage being shorter for reload.

To give some idea of the network architecture and the issue;

Head Office has a Pfsense firewall with a site-to-site IPSec VPN connection to some virtual machines in Azure. When on site (192.168.1.1/22) I have no issues communicating to the Azure VNET (10.0.0.0/16) or its VM's.

Samba not authenticating after upgrade

I just upgraded my Proxmox host, which also doubles as a storage server from buster to bullseye, which must have upgraded Samba as well. After this, I am unable to mount any Samba shares.

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.
