Wordpress Slowness Behind GCP HTTP Load Balancer

I am hosting a Wordpress instance on GCP Compute Engine (using the Marketplace image). It works great when I directly access the instance IP, and the latency is around 20 ms.

However, in order to make the site secure, I am using a GCP HTTP load balancer in front of the instance. I have pointed my domain to the load balancer.

When I access the Wordpress through the load balancer (either HTTP or HTTPS ...

Why does setfacl turn on the group execute permission on files even when specifying X?

I'm seeing strange behaviour with setfacl setting the eXecute bit on the group permission for files in some situations, confirmed on CentOS 7.

As user root with unmask 0002:

Some emails show blank on Squirrelmail

For some reason certain messages, only for some users, are showing up either partially or totally blank and are not selectable. The mail server is not self hosted (migadu.com), only Squirrelmail (v 1.4.22).

I've confirmed the messages themselves seem just fine and are perfectly fine when downloaded via another IMAP client. I'm guessing it's something specific about these messages, but I can't figure o ...

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.
