Drupal in subdirectory behind reverse proxy
pl flag

On my public-facing host, Apache works as reverse proxy to a non-public host, where a Drupal 9 instance is symlinked under the web root. Drupal answers to requests, but it outputs any local links with the symlink name included. Apparently because the PHP request variable $_SERVER['SCRIPT_NAME'] includes it.

How do I tell Drupal about it's "actual" base path?

Why do hosts disable PHP's fpassthru()?
ru flag

I've been working on a PHP application that uses the fpassthru built-in function, which reads contents from a stream or file pointer, and outputs them to the output buffer. It's very similar to the readfile function, but allows me to start the output at a specific offset.

Most hosting providers I tested my product with, worked just fine, and these include shared multi-tenant hosting environments. Howe ...

Raid Array with only a Partition of some Disks

I was wondering if one could set up a RAID-5 array such that only some space of the third disk is used in the raid array and the left over space can be used as a non-raid volume.

I have three HDDs with 2TB, 2TB and 3TB. The 1TB on Disk 3 should still be usable but not redundant. (on an ubuntu server)

How can I check if an email address is linked to a "personal" or a "business" Google account?

In other words, I need to know if a domain is registered for business use in Google or not.

I would like this to be a standalone method (i.e., I am not looking for an addon like Domain Checker, but rather to replicate what it does on my own).

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.
