Recently I was importing an Icinga configuration for testing purposes. Working with this configuration, I found that there were icon images assigned to the objects. Sadly, those didn’t display, because I didn’t have the icon set installed. So I thought of creating my own.

Serverless computing has changed the way developers build and scale applications. With event-driven execution, automatic scaling, and a pay-as-you-go model, it removes the need to manage servers and helps teams move faster. This is why industries like FinTech, e-commerce, and media streaming are adopting serverless at a rapid pace. But serverless also brings new monitoring challenges. Functions are short-lived, run in different places, and are triggered by many types of events.

For every SaaS leader, engineer, and operations professional, growth is always the main goal. You’re expected to release features quickly, keep user experiences smooth, and manage everything within a limited budget. But behind the scenes, your application may have hidden issues such as slow performance, unnoticed errors, and laggy transactions that quietly eat away at revenue, reduce customer trust, and exhaust your engineering team.

The Linux Foundation’s latest report, Open source as Europe’s strategic advantage: trends, barriers, and priorities for the European open source community amid regulatory and geopolitical shifts, provides key insights into how European enterprises are using open source software (OSS), as well as the barriers towards further development of open source in the continent.

Open source software is everywhere. Research shows that around 97% of codebases contain open source software, and it’s clear to see why. It’s always magical to realize that there are thousands of free-to-use, ready-built programs and code repositories that solve problems you’d otherwise need to spend weeks building the solutions for from scratch. However, like with all software, you still need to ensure that your software supply chain is secure and safe to consume.

Being “on call” sounds simple: you’re not actively working, but you need to be available if something goes wrong. The real question many employees ask is: do you actually get paid for being on call? The short answer is: it depends. Your pay may hinge on labor laws, company policies, and how restricted your time really is.

In 2025, inventory management has become a central challenge for all SMBs (Small and Medium-sized Businesses). Whether you run a retail store, a construction company, or an online shop, knowing where your products are, in what quantities, and at what time is essential to avoid stockouts and optimize costs. But with the wide range of tools available, one question often comes up: should you choose free software or invest in a paid solution? This article helps you make the best decision for your business.

Kubernetes, also known as K8s, is an open-source, portable, and scalable container orchestration platform. With K8s, you can reliably manage distributed systems for your applications, enabling declarative configuration and automatic deployment. Yet, K8s can be resource-intensive and costly, with a rather steep learning curve. But in 2019, a lighter, faster, and potentially more cost-effective alternative appeared: K3s. Still, K3s is not a magic wand that works for all Kubernetes deployments.
