Why does `apt-get -y install php8.0-dev` installs PHP 8.1
cn flag

On my ubuntu 22.04, I used the PPA from LC_ALL=C.UTF-8 add-apt-repository -y ppa:ondrej/php

I ran apt-get -y install php8.0-dev, which required php8.1-phpdbg and it went ahead and installed PHP 8.1 which replaced my PHP 8.0

I find this behavior puzzling, any idea why php8.0-dev relies on php8.1-phpdbg?? Thank you!

Does Prometheus efficiently compress series of identical samples?
cn flag

I need to capture high temporal resolution on the high frequency samples, and I'd like to know how Prometheus will handle the  ...

During which dracut hook can a PXE client rename predictable interfaces names with a udev rule?
jp flag

tl;dr: During load of an initramfs (execution of dracut modules) on a PXE client, I need to rename the kernel-given (predictable) interface names (right now they're unpredictable ethX names). This way, the PXE client will always boot from a predictably named interface. Currently I'm reading the hardware info with dmesg during the dracut cmdline hook. Could I cat a udev rule to /usr/lib/udev/rules.d/ ...

How can I use Ubuntu 22.04 with OpenSSL 3 and PHP sites? Getting errors due to a conflict
us flag

I have an Ubuntu 22.04 install and it is using OpenSSL 3. When I put my site on the server, I get this error:

file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages: error:0A000126:SSL routines::unexpected eof while reading

Searching for answers just tells me there's a bug with PHP 8.1 and OpenSSL3 on a Laravel app. So, how is anybody hosing PHP apps on Ubuntu 22.04?

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.
