I'm trying to setup some customer error pages on our Apache servers, which seemed straightforward. The 503 is working right, but the 404 is not. They're setup the same:

    ErrorDocument 404 /errorCustom.html

But when I hit a bad URL in the site, the Apache log clearly says it triggered a 404 as expected ...

Overview

We have a 300-user environment. Each time a member of staff leaves we use MDT fully wipe their machine and reinstall Windows 10/11. This means that while a new member of staff gets the previous staffer's computer, the machine was fully wiped with a fresh Windows 10/11 install.

We would like to improve this process by introducing additional steps in the MDT task sequence that would backup  ...

Issues with VLANs on Linux. Can ping hosts in other VLAN
cn flag

When I configure an ip address on a vlan interface from another vlan subnet, I can reach that other vlan subnet. But it should not be reachable.

For example:

  • On the switch, the port is configured as tagged with vlan id 500 only
  • On the Linux box the interface eth0.500 with ip address 192.168.10.30/24 can ping hosts in subnet 192.168.10.0/24, but those hosts are in vlan 3000

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.
