Permissions of /dev/null wrong in KVM guest
tr flag

My host node is RHEL7 running KVM from the 'updates' repo. On the host node, the permissions for /dev/null are:

crw-rw-rw-. 1 root root 1, 3 Dec 18 04:45 /dev/null

In an Alpine KVM guest (5.14, but same behavior on other versions), the permissions are missing the "others":

How can I persistently change the permissions in the guest to match the h ...

Connecting to computers within a OpenVPN network with SSH
us flag

I have OpenVPN installed on a VPS and I wish to connect to any computers connected to it via SSH by using the subnet IP provided by OpenVPN. For some reason, whenever I try to start a SSH connection (say from 10.8.0.2 to 10.8.0.3), it doesn't work. Not because the connection is denied but because it hangs as if it was unable to find the target. Of course, I am already assuming that all the computers alr ...

Does z/OS enforce memory protection between processes of the same user?
za flag

It is often pointed out that each user has their own (virtual) address space in in z/OS; this is said as if it is a good thing, and I suppose it is compared to real mode. But in most modern systems I'm used to most processes (or jobs, in z/OS parlance, I suppose) having their own address space. This Unix approach seems strictly more secure at first glance.

That said, I have heard it claimed that z/OS ...

nginx proxy_pass of different subdomains to different locations within one server block
br flag
aag

The typical way of reverse-proxying different subdomains to different places with Nginx is to install a unique server for each subdomain, like this:

server {
    server_name subdomain1.example.com;
    location / {
        proxy_pass       http://hostname1:port1;
    }
}
server {

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.
