What is a good indicator that a server does not have enough RAM?
mx flag

I am the "application owner" of a server (ie. I am responsible for running and maintaining the application running on the server).

The VM has 8GB of RAM, as was recommended when the application was first installed, but in the latest version recommendations, 32GB are indicated.

The ops team is relunctant to quadruple the RAM, as the server is only using 30 to 40% of its 8GB of RAM today.

Is used RAM the o ...

NixOS starting a daemon process example - is the example broken?
cn flag

In the python flask example application given on https://nixos.org/guides/dev-environment.html ... Isn't it just killing the daemon process whether it passes the health check or not? Maybe there's something implicit going on that I'm not grasping?

You can also run a bash script like this one in your CI to make sure your default.nix keeps working in the future.

How to change default firewalld behaviour to drop all established connections on reload
cn flag

I have a web-server and sshd services running and listening for connections on their ports. What I want to achieve is when I change my zone from public to something that prohibits ports 22 or 443, my current connections will expire. Right now after prohibiting those ports and reloading firewalld, connections are still alive.

I think this can be achieved by adding a direct rule, but I don't know h ...

High load and file descriptors but idle cup usage
de flag

I have a problem with NFS & PHP. I changed the NFS mount on some of my servers using Ansible, but I forgot to change the NFS mount on this server. After 4-5 days, I saw the system load on this server at around 50 (the server has 8 cores!), but CPU usage has not changed. I troubleshoot and change the NFS mount to the correct one ( in screenshots when load stays at 50 and file descriptor goes down). B ...

How to pass an html site from another server via nginx reverse proxy?
cn flag

I am trying to load an Angular app from another internal service when calling localhost:81/internal?pageId=10. But all that happens is that nginx redirect me in the browser to localhost:80.

    proxy_pass http://192.168.1.100:8080/public/internal$section;

Best approach for specific local server permissions?
cn flag

We are trying to set up a three step permission-structure (Firstline, secondline, thirdline support). Firstline can only RDP with user-rights to all our domain-servers, no problem there with restricted groups GPO.

Now to the problem, secondline should be able to RDP + Update applications and restart services. How do I achieve this via GPO? Where I look it's the other way around, DON'T alow users  ...

Creating an OpenLdap specific administrator group on LDAP
bm flag

I'am trying to create a simple specific administrator group on my OpenLdap server that is running slapd. There is currently no slapd file, and I have been working with the cn=config format.

For example:

Co-locate VM on a single/set of core(s)
us flag

I'm trying to understand certain impacts of virtualisation on performance by running benchmarks on VMs. I'm considering ESXi and Hyper-V as the hypervisors. I wanted to know if I can pin a VM to a particular core or set of cores. If possible, I could then pin 2 VMs to the same core and try reading into the effects when there's a memory intensive job running in both

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.
