    dockcheck: A CLI Tool for Updating Container Images

    dockcheck is a CLI tool that checks for Docker container image updates without pulling images first. It supports parallel processing, automatic updates, exclusion filters, and notifications via multiple channels (Matrix, Telegram). Configuration is handled through flags or a config file, with Docker Compose labels for fine-grained control. The tool can be scheduled via cron for automated update workflows, with options to delay updates until releases stabilize. Community contributions have added integrations for Prometheus, Zabbix, Unraid, and Synology DSM.

    FileBrowser Quantum Hits Stable!

    FileBrowser Quantum, a fork of the original FileBrowser project, has released its first stable version after years of development. The project now offers two release tracks: stable for general users and beta for early adopters. Key features include OnlyOffice integration, two-factor authentication, OIDC single sign-on, granular access controls, and advanced file sharing options. The application supports multiple platforms including Windows, Linux, macOS, FreeBSD, and Docker. While it indexes filesystems for fast search (which can increase memory usage), this can be disabled. The project is actively maintained by two core contributors and welcomes community involvement.

    12 Networking Fundamentals Every Engineer Should Know

    Networking fundamentals are explained through the evolution of a fictional travel booking website from a single server to a complex cloud system. The content covers IP addresses and DNS for device identification, ports for application routing, subnets and routing for network segmentation, firewalls for security, and NAT for private-to-public address translation. It then progresses to cloud concepts like VPCs, containerization with Docker including bridge and overlay networks, and Kubernetes orchestration with pods, services, and ingress. The core principle is that fundamental networking concepts remain constant across physical servers, cloud infrastructure, containers, and orchestration platforms, even as the tools evolve.
