Temporarily disable minimum password time in FreeIPA after password reset by support
bi flag

We use FreeIPA 4.6.8 and we have users that of course forget their passwords. However, password policy has a minimum password time of 1 hour. When support resets their password for them and provides it via separate & secure channel, they also send instructions that instruct the user to reset the password to something else at next login. However, since support used the 'reset password' utility in Fre ...

What are the scalability concerns with pub/sub servers?
cn flag

I'm looking into setting up a pub/sub service with websockets. From what I can tell the scalability bottlenecks will mainly be with memory, which affects how many sockets can be opened at a time, so therefore I would think it wise to split this off of the other servers running services such as APIs. Is this correct? I would imagine memory is more expensive than compute power when it comes to hosting, so ...

Azure strange behaviour in AIP activity explorer

The AIP activity explorer in compliance.microsoft.com started logging activities from outlook.office.com. It started 15.09, but I activated Azure RMS 16.09. It started logging activities only when a user sends an email outside of the company.

Why is that ?

How to run service after kernel module is loaded

I have been breaking my head over this the last few hours. On one of my machines the intel-rapl-msr driver is buggy and reloading it fixes the issue. I thought I could trivially create a service that does this on boot. But I can't get the service to load after the driver has loaded.

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.
