Sharing notes from my ongoing learning journey — what I build, break and understand along the way.
IoT-Based Autonomous Wind Power Plant Management and Bird Protection System This project is an interdisciplinary study that combines my professional background as an Environmental Engineer with my current training as an IT Specialist for System Integration. The primary objective is…
Kali Linux on VirtualBox: Key Advantages, Features, and a Practical Workflow When the name Kali Linux comes up, a large part of the internet quickly steers the topic toward “hacking.” But what truly makes Kali valuable isn’t individual tools or…
Network Troubleshooting: A Structured Method to Find and Fix Connectivity Issues Network troubleshooting can look a bit intimidating at first, because problems rarely come with a clear error message. A user says “the internet is down,” but the internet is…
Network Planning and Infrastructure: How to Design, Cable and Document a Reliable Network From the outside, network planning can look like “run cables, place a switch, get the internet working.” But once you look a bit deeper, you realize this:…
WLAN Explained: How Wi-Fi Works, Which Band to Use, and How to Secure It Wi-Fi is often seen as “set up the modem, type the password, done.” At home, for most people, it really is like that. But once you…
Firewall, NAT and DMZ: How Network Security Really Works in Practical Setups When you’re just starting to build a network, the goal is usually simple: devices should get internet access, servers should run, and everyone should be able to do…
DHCP and DNS Basics: How Devices Get IP Addresses and Resolve Names in Real Networks When we first check whether a network is working, we usually measure it by the cable, Wi-Fi, and the question “Is it getting an IP?”…
Routing and WAN: How Routers Choose the Best Path Across Networks Once you’ve somewhat internalized IP and subnetting, the next question naturally appears: “Okay, devices in the same subnet can find each other. But how does traffic travel between different…
IP Addressing and Subnetting: How IPv4/IPv6 and CIDR Define Network Boundaries As someone new to networking, IP addresses can initially feel like something you just memorize: numbers starting with 192.168… and then expressions like /24, /26 on top of that.…
From Switching to VLANs: How Trunks, Tagging and STP Keep Networks Organized As someone new to switching, the confusion usually starts at this point: “I plugged in the cable, the devices can see each other… so is the job done?”…
