Optimize WSUS for work-from-home users
it flag

We self-host our infrastructure. Most users work from home using (more or less) poor Internet connections with VPN.

Besides MS E5 and third-party options, is there a (documented) method of getting over 150 users up to date via WSUS remotely?

I have approved some updates, but from the WSUS Dashboard there are still computers either not signed in for the past 30 days or updates needed by computers.

I plan to deploy in an ubuntu server, via docker, a django web application with postgresql database in a local machine within a local network. I believe that docker volumes live in the /var/lib/docker/volumes directory of the host computer. My question is: I suppose this means that when I prepare the host machine, I will have to allot a large portion to the root directory? Are there ideal sizes (e.g. in ...

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.
