ksoftirqd maxing out for network interfaces

We have a Debian server with one link to the internal VLAN, and one to the external - both connect directly to the same switch.

On both links, we're intermittently seeing an unusually high amount of bad receive events, as well as high latency.

Start with Jenkins in k8s on Linode / Vultr / DigitalOcean

I'm going to setup a basic jenkins infrastructure to deploy to my website. Very basic stuff.

I want some dedicated machines / compute engines for it. So I'm thinking of using a Kubernetes cluster from Linode, Vultr or DigitalOcean.

I'd like a Jenkins Master to be up and running 24/7 and the worker nodes only on demand. The way I see it is that I have to configure Kubernetes to use certain nodes whic ...

I have a Spring Boot application running currently under Tomcat 8.5 that has a shibboleth-based SSO integrated. Shibboleth and tomcat are connected using apache2 mod_shib and mod_jk, using default Debian 9 packages.

How to get qemu watchdog working in Freebsd 12.1 guest
cn flag

I am running a couple of OpnSense (based on FreeBSD 12.1) routers in qemu virtual machines in Proxmox 6.4.

Promox has its own non-libvert way of configuring VMs, but to add a watchdog device, one adds the following line to the VM config file:

watchdog: model=i6300esb,action=reset

I can see that this is working and the virtual device is present in the VM because pciconf -l -v in the guest includes the  ...

Is a ZVOL considered copy-on-write anymore if I format it with another filesystem?
ke flag

According to official requirements from Microsoft, SQL Server 2019 only supports either ext4 or xfs. I suspect that a Copy-On-Write filesystem such as btrfs or zfs may hurt the performance of the database. There can be bugs and other compatibility issues as well.

What if I create a zvol and format it with xfs, then put the database on top of the xfs filesystem? Theoretically, SQL Server daemon only kn ...

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.
