cn flag

What is the equivalent to sha256sum -c in Windows?

I have a set of very important files that I need to copy-to and mirror across many different types of disks in many geographically distinct locations. After relaying the contents to disk via USB, ethernet, fiber, radio, telegram, and signal fires (some of which are more reliable means of transmissions than others!), I want to check the integrity of the  ...

We are experiencing a http2-to-http1.1 downgrade behaviour of IIS 10 we do not really understand. We have implemented a REST API (frontend: Angular, backend: php (using laminas-api-tools). For our GET, POST and PUT requests, everything is fine. However, when we send a DELETE request that is supposed to be answered by status code 204, the following happens:

keepalived virtual and real server in different subnets
ru flag

My goal is to forward the SMTP traffic from one unused server to another using keepalived. The problem is, that the other SMTP server is in different subnet. I have configured keepalive in the following way.

Configure winrm https certificate from non-admin user
us flag

Using letsencrypt as a CA, a non-admin user automatically requests a new certificate to be used by the winrm https listener once the old one is about to expire. To make winrm actually use the certificate, the CertificateThumbprint of the listener needs to be set to the new certificates thumbprint.

This can be done like this:

Set-WSManInstance -ResourceURI winrm/config/Listener `

Multiple email addresses (send and receive) per user with a single Active Directory account?
lu flag

The company I work for has multiple brand names e.g. Contoso and Acme

The users need to be able to send and receive emails from both [email protected] and [email protected]

Now if John replies to an email addressed to [email protected], the reply address should automatically be [email protected] (and the same for [email protected] of course)

The infra service provider we use has solved this by c ...

Disabling email for Prometheus Alertmanager based on severity
ru flag

We are monitoring a HPC computing cluster using a combination of Prometheus, Alertmanager and Grafana. On our machines, things like SWAP memory filling up to essentially the limit happen frequently, and while it is useful to see the corresponding info-level alerts in the Grafana Alerts dashboard, we would preferably not send the corresponding emails.

Is there a way to mute/disable all, say, alerting ema ...

Why does drop_caches increase "available" memory
in flag

I encounter low memory issues on proxmox 7 nodes I'm managing. When reading about similar problems I was directed to linuxatemyram.com, after reading this page I started monitoring "available" memory instead of "used" memory. But the problem persisted (available memory decreases with uptime).

I then found that I could force free linux caches by issuing the command echo 3 > /proc/sys/vm/drop_cache ...

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.
