How to connect to a Cisco VPN in "native mode"?
gh flag

I need to connect to a VPN, but I am not an expert on the subject at all, so if anyone can help me, I would appreciate it.

I was given the following data, telling me that this info is for a "Cisco config in native mode". I am going to paste literally the words in the email:

Are MySQL/MariaDB and Postgresql compatible?
cn flag
Yav

I want to install multiple applications on my web server. For most of them, using PostgreSQL is possible or the only option. But in one of them's installation guide, only MariaDB is mentioned. If I create a PostgreSQL database, will it work on the software that only talks about MariaDB too?

Nginx Plus, PM2 Plus, or Both
np flag

My company has a few node/express apps that I would like to get some sort of monitoring set up for. Currently, they are all being run with PM2 in cluster mode, then using Nginx as a reverse proxy/webserver.

I would assume that PM2 Plus would give more application-specific stats, such as memory usage, logs, etc. while Nginx Plus would give more of the web server stats like number of connections, l ...

GPU Acceleration on a Windows Server without virtualization over RDP
us flag

I'm trying to find out if it's possible to run a Windows Server with one GPU which is shared between all RDP clients so that people could

  • create a session on the server
  • start some program with a UI which needs GPU acceleration
  • disconnect afterwards while the program stays running and gets full acceleration
  • later reconnect to the session

Maybe that's an unusual use case because most things i can find ...

Does iptables rules have control over raw socket packets?
us flag

A program I use generates some TCP connections using raw packets mode. Let's say that I executed those two commands:

/sbin/iptables -A INPUT -s 8.0.0.0/8 -j DROP
/sbin/iptables -A OUTPUT -d 8.0.0.0/8 -j DROP

Is it safe to assume that no packets will be sent to that network?

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.
