Do not route local network traffic via SoftEther VPN
ve flag

I'm confused with configuring that the local network traffic is not routed via VPN. I want to use the VPN (connecting via Windows SSTP client, not using SoftEther client) at home (local ip: 10.0.0.2, gateway: 10.0.0.254, subnet: 255.0.0.0) and in other public networks.

To access my services in my local network at home, the VPN should not route traffic which is going to 10.0.0.0/18 to my VPN serve ...

Allow parameters to fill form fields
us flag

Nginx is sending a 403 Forbidden when I attempt to use a parameter in my URLs. I want URLs like this one to fill the URL field on any page on the site.

https://example.com/?url=https://example.com

I am not handy with nginx, so any detailed steps to change this would be great. I'm guessing I have an nginx directive somewhere that disallows parameters.

Why does `df` and `du` report free space differently on Ubuntu 18.04?
br flag

Why would these two commands report free space so differently? This started happening last year on several Ubuntu 18.04 VMs from time to time.

df reports 100% used while du -smh shows only 2.3G of the 4.0G (total) in use.

This is often followed by rsyslog or syslog-ng filling up /var with error messages when the syslog server is down for maintenance.

postgres container uses only one cpu
cn flag

I'm doing a lot of SQL inserts and the limiting factor appears to be CPU assigned to postgres. Most of these inserts are to the same table. I'm a bit confused here as I'm using docker-compose with no resource limits, the container should use all available 16 cores.

inside container

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.
