uWSGI aborts responses, loses connection to nginx
gb flag

I'm running a small web application written in Python, running in uWSGI and served through nginx. There's a component that generates ZIP files for downloading, which occasionally can be quite large (several GB). It often happens that the connection between nginx and uWSGI is broken and the request is aborted; nginx ignores the truncated response while the browser runs into a timeout because it keeps the ...

Why does grub's os-prober add entries with `linux` instead of `linuxefi`
cn flag

On my system, I have two copies of CentOS 7 installed, and one copy of Windows 10 Pro. Every system is bootable and works correctly, and is fully up to date (kernels, packages, the works).

When I run grub2-mkconfig in either copy of CentOS (one host called pingu, the other pinga, for reasons), a new grub configuration is created. Part of it is generated through the os-prober template.

Too many RPC connections make web socket closed

Several servers are connected via RPC. There are times when apps in OS have too many RPC calls, which causes the network to become closed. What is the best way to debug or configure my OS?

Is it possible to deploy fully configured CentOS 8 installations over PXE? Non-interactive

I have a central virtualisation cluster with a mirror and PXE server on it.

I've been able to PXE boot into a fresh CentOS 8 ISO from the remote machines, and am looking into configuring it post deployment with %post or ansible.

However, what I'd really like to do is that a pre-configured VM, clone the filesys ...

We have a linux ec2 instance.

One of us logged into our ec2 and ran a command, say python --version.

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.
