How to debug FAILED - RETRYING: wait for hosts (12 retries left)
cn flag

Trying to deploy a VM landscape using https://github.com/GoogleCloudPlatform/sap-deployment-automation, I often get the message:

FAILED - RETRYING: wait for hosts (12 retries left).

It usually repeats failing, and I resolve it by trying various things to enable ssh access. But this time I would like to get some ideas how to make it better than blindly trying.

How can I debug Terraform?

Stress test a server running on the local machine?
in flag

I tried searching around and everything gives me completely different answers

I'm comparing nginx and a proprietary server my boss wants to use. We're trying to figure out if it's a lot slower or roughly the same. Both are http servers (we don't care about https unfortunately but I'd like to check for that too)

I suspect we'll want to know number of simultaneous connections (how many can make a requ ...

I have a backend system used for IOT devices which use UDP protocol for communications. And there are certain TCP (HTTP2) based APIs for mobile apps from the same backend.

I am trying to build a rolling update feature to enable 0 downtime patching of the backend services.

My setup is like this.

Instead of directly exposing the sockets to the apps, I am trying to do transparent proxy to my processes. I  ...

I'm trying to setup docker on a company VM on Ubuntu 20.04.
At first I couldn't even start the service because it seems there was a conflict with the pre-existing routes. If I run the route command I get this:

Web server to run an executable binary using Heroku
cn flag
zli

I'd like to create a web server which serves REST APIs. Most of the functionality on the server side already exists in an executable binary or some shell script. So instead of rewriting this functionality in the API, the REST API is just a thin layer which calls the executable binary and returns the response. I'd like to try to use Heroku for this, but open to other options as well. A few questions:

Ubuntu 20.04: trying to get syslog-ng and rsyslog to co-exist with systemd

I am stuck with rsyslog running in a corporate straight jacket. The config is completely set.

I need to run a service to relay logs from a variety of sources and I use syslog-ng for this.

I have this running on an older ubuntu system using a locally compiled and packaged version of syslog-ng. I would much rather not have to compile things when I don't have to.

The problem(s):

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.
