MongoDB authentication instance without cluster i.e. using mongos router without a sharded cluster?

So my question is:
Is there a possibility to have something like a Mongo authentication instance running on a VPS, together with fail2ban, which only forwards authenticated requests to a home server MongoDB? The trouble of setting up a whole shared cluster in order to be able to use the mongos router seems a bit overkill for my hobby purpose.

Varnish - detach and attach cookies

First of all, I'm asking to find out whether this is possible or not.

So, I can see Varnish will not cache objects if it has cookies.

I'm thinking about when an incoming request has cookies, Varnish will store them in variables and remove those cookies, and then let it through to the backend. Once the backend finishes processing it, Varnish will put back the cookies.

How to install PHP Sodium on Ubuntu 22.04

I'm running a Google Cloud server running Ubuntu 22.04. It's a typical LAMP stack (PHP is version 8.1.2). Some of the websites on the server are using Laravel 8.

I recently upgraded one of the websites to Laravel 9 and I received the following error:

From a little bit of research, apparently this is caused by a PHP extension Sodium missing.

Does NetApp allow third party tools to get access to the volume directly?

NetApp has a notion of

  • logical storage,
  • volume used and available space

The logical storage deviates from volume used and available space, because the used space has storage optimizations like deduplication and compression.

Does NetApp allow third party tooling to get access to the raw read-access to the potentially-deduplicated and potentially-compressed volumes?

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.
