Debian 11 security updates: deb or security, which to choose?
br flag

I'm in the process of upgrading my first system to Debian 11 / Bullseye following Debian's 41-point-plan. The sources.list entry for security updates has changed and according to the documentation it should point to the server deb.debian.org. On Debian 10 and a fresh install of Bullseye it points to security.debian.org. These are actually different servers, with deb returning a single IP and securi ...

FTP Nautilus ( Ubuntu Filemanager ) overwrite File with empty content
pr flag

I connect via ftp or fstp. When saving, it happens that an existing file is overwritten with empty content.

I use nautilus and I have not started any tests because it is an online shop that is in operation. (local machine Ubuntu 20.04, server machine / version not sure)

I recognised via winscp that the files were empty. I had the data locally, but when I saved it, it loaded itself to death and then  ...

Providing cloned virtual environment to multiple clients
br flag

I have a virtual environment created with vmware esxi consisting on a ipfire and a internal network with some vms.

What would be the best way to clone this environment, on demand, so each client could have access to a vpn that leads to copies of the same vms on his own private network? (the client would only have a ovpn, or other, and connect to the vms).

I want it to be scalable, since I don't know ...

SLES 11 PV VM on KVM
br flag

I have SUSE 11 SP4 VM, initially it was working on Xen in PV mode. Now I am moving it to KVM. My usual approach is to netboot any Linux in target VM, mount root of target OS, chroot and rebuild initramfs, then reboot VM into target OS.

SLES 11 SP4 seem to lack something because after that initramfs can't find any vbd device to mount root. However, I have managed to run it via direct qemu command  ...

MySQL is not using my certificate, uses its own self-signed

I have tried to find an answer to this and I have come up empty.

I have a certificate from LetsEncrypt that I use for all my SSL needs. It is valid for all the DNS names that I am trying to use. Today I tried to get it working for MySQL, but MySQL insists on using its own self-signed cert.

MySQL version is 8.0.26-0ubuntu0.20.04.2 from Ubuntu packages.

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.
