Understanding how Unbound listen on Port 53
ps flag

I have installed unbound on Debian Buster. Now I wonder why unbound listens 2 times on each Protocol.

netstat -tulpn

What tools do you use to measure your MTTR as the Ops Team?
cn flag

and do you measure it at all?

My problem is that when outage is alerted, it feels waste of time to create a JIRA ticket first, so I start solving it right away. Besides, some outages are solved by workarounds first and then revisited to solve them properly.

Windows VPN Client - Dial more than 2 concurrent connections
cn flag

I frequently need to dial multiple VPN connections to different isolated sites. I would like to have multiple connections active concurrently, but Windows (10 and 11) seems to limit the number of active connections to 2. Whenever I try to dial a third connection, I get an error saying "The modem is already in use". It happens for any combination of connections. How do I increase the two connections limi ...

How do you make nodejs server
in flag
Leo

This is some of the code in nodejs.

const app = express();
const server = app.listen(3000);

app.use(express.static("public"));
console.log("Server is running");
const io = socket(server);

It works on local host. What do you have to do for anyone in the world to be able to connect to it.

How to connect a RDP machine to a VPN?
cn flag

When I try to connect my RDP machine to a VPN(PPTP), I get disconnected from my RDP.

My understanding so far is that all the traffic, including the RDP traffic, is being routed to a different interface (the VPN interface), so the route of the RDP traffic has changed, so I get disconnected.

My research has lead me to the concept of split tunneling, which basically allows you to route traffic for spec ...

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.
