AWS AppStream Fleet maximum Idle Disconnect Timeout
il flag

does anyone know if there is a way of setting the "Idle Disconnect Timeout" from an AppStream Fleet to value greater than 60min? The UI allows for a maximum of 60 minutes, but this is ridiculous for many applications.

I remember someone saying that you could bypass this by changing something in the registry, but I couldn't find any references about it.

Purchase a ssl cert for a domain without a webserver

My company has a legacy web application where there is a link to help documents. The link is https://help.example.com.

OpenLDAP meta backend with different directory structure

I am working on a project and we need to "combine" two completely different Active Directory (AD) servers to one. I have found that OpenLDAP might provide a solution by providing a reverse proxy with the meta backend. However, as the documentation for this backend is incomplete and the tutorials and guides are fairly old I am not certain if this works.

My question is if it is possible for me to c ...

When trying to set up Azure AD and Google Workspace integration it seems that all suggested setups assume that one want to use AD to administrate users.

ECC DDR5: EC8 (80-bit) vs EC4 (72-bit) data integrity capabilities?

I have been looking info about ECC on DDR5 DIMMs (full ECC, non on-die ECC) and I have seen that there are two different types:

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.
