When you first commission a home server or NAS, setting up the operating system on a single, fast SSD is quick and straightforward. But as your services grow—hosting Docker containers, databases, storage shares, and automation routines—that single OS drive becomes a dangerous single point of failure (SPOF). If that primary drive suffers a controller failure… Read More: Bash Script for Zero-Downtime Linux OS Mirroring: Converting a Single-Disk… »

How to Herd AI Models to Be Productive Engineering Partners

Left to their own devices, AI models are like cats: brilliant, but notoriously difficult to herd. Without a strict framework, even high-reasoning Large Language Models (LLMs) will drift into inefficiency, introducing architectural decay. To build production-grade software instead of a mountain of technical debt, engineers must enforce a methodology that treats AI as a disciplined… Read More: How to Herd AI Models to Be Productive Engineering Partners »

The payments industry has a growing division of labour, and it isn’t between national banks, payment operators, commercial banks and fin-techs. It is between the people who build infrastructure and the people who make slides about it. Every major regulatory shift—ISO 20022 migration, SEPA Instant mandates, Request to Pay, Open Finance—spawns an entire ecosystem of… Read More: Who Actually Builds Infrastructure?

Modern family life comes with fragmented financial tools: checking accounts across different institutions, investment portfolios, retirement funds, kids’ allowances, and subscription trackers. Handing all this data to commercial SaaS platforms often means accepting recurring subscription costs, privacy compromises, and third-party tracking. I was looking also for a way to have a global look on all… Read More: Building a Self-Hosted Family Financial Hub: Wealthfolio, Actual Budget, and… »

Building an Automated Unified Monitoring Stack: Integrating LibreNMS, SNMP, Tailscale, UniFi & UISP APIs

Executive Summary Observability in a multi-site network requires more than simple ping checks. To maintain high availability, detect performance degradation, and monitor system health across multiple locations (Sopor Site and Mircea Eliade Site), we built a centralized, automated monitoring hub powered by LibreNMS. This architecture unifies SNMP polling, Tailscale mesh network routing, UniFi Site Manager… Read More: Building an Automated Unified Monitoring Stack: Integrating LibreNMS, SNMP, Tailscale,… »

Multi-Site Homelab Mesh Networking: Building a Zero-Trust Network Overlay with Tailscale & Subnet Routing
