Hosting .NET Core Razor Application on Ubuntu 20.04 with NGINX
cn flag

I have started trying to self host some projects to get a better understanding of the Networking/Hosting principles and I have been having an issue with hosting a .NET CORE app in Visual Studio following the Razor MVVM pattern.

Main question is, is this even possible or does it need to be on Windows Server?

I initially wanted to create two websites off the same domain ie game.domain.com and api.domain. ...

Strange Port Forward Behavior
de flag

I have multiple facilities with a Sierra Wireless Modem/Router with ports forwarded to an Ubuntu Edge Computer (443 web interface, 22 SSH, etc.)

Recently, we're seeing strange behavior where the forwarded web interface loads extremely slowly, or won't load at all. The web interface to the modem itself has similar problems.

However, the SSH port forwarded to Ubuntu is working normally. And, even stra ...

How can I tell my Ubuntu 20.04 is running dhcp client?
fr flag

I have a system that runs Ubuntu 20.04. However, it doesn't seem to be set as a DHCP client.

Google Consent Screen and Google Cloud platform showing different scopes
iq flag

I've been trying to communicate this. In my Google Cloud Console, it is only showing the auth/calendar/events scope (which is the one that we want)

enter image description here

But on the actual consent screen when I go to connect the integration within our application, it still shows the description for the other scope (auth/calendar), which we don't want:

Making applications hosted on third machine available through RDP?
br flag

We have a RDP "jump box" which is the only machine on our local network allowed to get incoming RDP connections. Is there a way to make applications on another machine (not the jump box, but on the same network) available on the RDP-jump box without having the user create another RDP session?

Why does our Tomcat Java application suddenly open hundreds of connections to our database?
it flag

We have a Tomcat application running on Elastic Beanstalk and our MySQL database is hosted on AWS RDS (2 or 3 t3.medium instances). Ever since we upgraded from MySQL 5 to MySQL 8 (currently 8.0.23), we've been having an issue that occurs about once a week. Most of the times the database is fine, but then, all of a sudden, the number of connections skyrockets (sometimes even surpassing the 307-connection ...

"AWS CIDR is not within the CIDR ranges of VPC", but it is?
th flag

many questions on this, but this time doesn't seem as obvious as the others.

I'm trying to split a VPC in two subnets.

I start with VPC 10.0.0.0/24, 254+1 IPs, from 10.0.0.1 to 10.0.0.255

I create the first subnet with 10.0.0.0/25, which should reserve one 0 bit of the address. Gives me 126+1 IPs from 10.0.0.1 to 10.0.0.127. Works fine.

The next subnet i try 10.0.0.128/25, which is the same as be ...

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.
