KVM: Best performance for all guests
cn flag

With KVM, what is the best way to provide the highest possible performance to all VMs?

The host has a hexa-core processor and 64GB of ram. 3-4 VMs should run on it.

The VMs are idle a lot of the time, but during performance peaks they should preferably have the full performance of the host available.

Is it a good idea to give all VMs 6 cores and 64GB of ram? Or what would make the most sense?

Windows 2016 Server NTP error
cn flag

I have a Windows 2016 Server, up to date. It is not a part of AD.

The time it set up to synchronize with NTP server. The time on the server is wrong. When I update the NTP server and hit "Update now" the time gets updated to the correct time for a second and then jumps to the wrong time again.

Did anyone got the same error? I only found AD relevant issues.

Multiple SSL certificate types on the same server
cn flag

Can i have two types of certificates installed on the server at the same time?

I need a wildcard SSL to protect a single domain and all its all subs. I need a UCC/SAN SSL to protect multiple other domains.

My assumption is i can buy one of each, install both and use the standard wildcard as the main SSL and SNI for the other sites?

How to limit UDP port range with K8s + Calico + Wireguard
id flag

We have several Kubernetes clusters at Hetzner using Calico (vxlan) with security enabled (Wireguard tunnels). The recent Hetzner outages knocked everything offline:

Due to always different destinations (IPs, ports, packet size) we unfortunately had to limit this traffic. This concerns UDP traffic on port 9000-65535.

Is it possible to configure Calico to not use UDP ports from 9000-65535? Is this lik ...

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.
