SSH to Windows server, fetching public keys from LDAP
cn flag

We've got an established process where users connecting to an Ubuntu server via SSH have their public keys retrieved from our LDAP infrastructure and then PAM sets up their home directory, etc.

I need to set up a standalone Windows server but the users still want to use SSH to connect to it. I'm therefore looking into how to try and replicate the Ubuntu experience onto Windows.

As far as I can tell, ...

I'm looking for a way to limit Nginx for location to a number of requests per second independent of the origin IP. From my understanding the rate limiting feature is IP sensitive which cannot be turned off.

What would be the right approach here?

PHP PDO Very Slow on Fetch

I have a problem with a couple of queries running in PDO on PHP connecting to MSSQL server 2019. I have checked the time in SSMS and its fast. I have also added some timers into my code so I can see the time to execute the query and the time to fetch the data.

I have found the fetching of the data is the issue.

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.
