The packet goes through the other router
lc flag
rei

I want to connect two hosts in parallel with two different models of virtual routers. These are made redundant by VRRP.

Originally, packets are sent through only one of the routers. However, when the packet is sent, it goes through two routers. This results in duplicate ping packets.The traceroute now looks like this.
host1:$ traceroute -I 192.168.1.1

  1. 192.168.0.2
  2. 192.168.1.3

I have recently created a few python applications which store data in PostGres and requests to read/write take time; since they are not stored on RAM and they are massive bottleneck to speed. Which would still work if the numbers of users are less than 10 and even with 100 with queuing it could ...

My Apache2 server got pwned, need some help uncovering impact
lv flag

So I'm pretty sure that my home Apache2 server got hacked. This is in a VM running on my server. I was using this server as a https proxy/reverse-proxy for my other applications I have running at home.

What happened was that I created a too small disk and that got full. Then, it got full and my unattended upgrades weren't running anymore. I was stuck at apache 2.4.38. That's completely my fault.

CyberPower UPS: What does "Line Interaction... None" mean?
ir flag

I've got a CyberPower VP700EILCD UPS connected to a Linux box. When I run pwrstat -status, I see (amongst other things):

Line Interaction............. None

What does that mean, exactly?

I assume it means the UPS is currently not using its autotransformer to increase or decrease the voltage output, is that right?

Or does it mean the UPS needs to be configured to use line interaction, or even does not ...

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.
