Issue #87: Lightweight Kubernetes
K3s, k0s, and MicroK8s vie for performance honors on the control plane and data plane in artificially created extreme stress scenarios.
DVD contents are not available with the digital version of the magazine.
The digital issue will be available in early June 2025.
Lightweight Kubernetes
We compare the k0s, K3s, and MicroK8s distributions for environments operating under resource constraints.
Coroot
In the deep waters of scalable environments, observability is more important than ever. Coroot enters the scene with eBPF to intercept traffic and collect data that is of interest for monitoring and attack detection.
NAPS2 SDK
A NAPS2 PDF scanner, the C# language, and the .NET Framework set the stage for a CLI app that scans documents.
Rescue Systems
Rescue systems play a particularly important role for desktops because they cannot simply be reinstalled on the fly. We look at venerable but outdated Knoppix and three systems still in development: Grml, SystemRescue, and Finnix.
Optimizing File I/O
File I/O is a limiting factor for many applications and can become a bottleneck for data-intensive computing. We analyze different file access functions and present a script that visualizes and optimizes inefficient file I/O.
Netdata
Netdata relies on easy commissioning and a hosted cloud service to simplify monitoring, alerting, and trending. More than 300 services can be monitored in addition to basic system parameters.
dockle
The open source dockle tool can help keep your Docker containers compliant.
WireGuard Portal
The wg-portal project helps you set up, manage, and scale a WireGuard VPN environment.
IVRE
The IVRE tool integrates into existing IT infrastructures for reconnaissance on private networks to help analyze endpoints accessible over the Internet.
Intro to Software Licenses
Software licenses tell you how you can use software packages and legally deploy the software in your projects. Fortunately, tools can help you automate the process of verifying licenses.
Updating with Ansible
Ansible has earned an excellent reputation as a tool for configuration management. Thanks to playbooks, updates are more or less child's play.
Get-NetTCPConnection and ss
This Windows cmdlet and Linux utility are efficient and powerful tools for monitoring network connections and identifying potential security threats on Windows and Linux.
AIX Toolbox
Starting your journey with open source software on AIX has never been easier with the IBM AIX Toolbox.
AD Risk Mitigation
Active Directory default settings could expose your AD environment to security vulnerabilities. We look at account hygiene and risk mitigation in authentication, login data, PKI, domain join, and more.
