Linux
Kernels, shells, systemd and day-two systems administration — the commands, the configs and why they work.

Replace Google Drive, Google Photos, 1Password, Plex, and your document scanner with a self-hosted stack that runs on your hardware. Complete Docker Compose setup with Traefik, Nextcloud, Vaultwarden, Immich, Jellyfin, and Paperless-ngx.
There is a fifteen-year fork tree underneath every Minecraft server, and most admins copy a jar without knowing what's in it. Here's the whole chain, with the code — including the config key most DAB guides get wrong.
Back in February 2026, Linus Torvalds rejected the entire MMC subsystem pull request for Linux 7.0, calling it "complete garbage" and "untested crap" because it didn't build properly and bypassed linux-next. Linux 7.1 gets it right.
Linux 7.0 RC6 landed with more fixes than Torvalds wants to see this late in the cycle, and RC5's calm turned out to be a mirage. He's not panicking yet — but he's also not making promises about the release date, and he suspects better AI coding tools might be partly responsible for the noise.
Your server dropped to 12 TPS. You copied Aikar's flags. You upgraded Java. Nothing changed. That's because JVM flags don't fix plugin bugs. Here's how to find what's actually killing your tick budget.
Every six months the same thread appears and nobody maps the JVM engineering onto what a Minecraft server actually does. This does — version by version, with the flag most guides still tell you to set that will eventually stop your server from booting.
How AI infrastructure demand is driving up VPS and dedicated server costs — and why your hosting bill is going up even though you haven't changed anything.
An attacker starts with a low-privileged shell or user account and escalates to root or Administrator using misconfigurations, SUID binaries, kernel exploits, and Active Directory attacks. Here's every technique, the tools professionals use, and how to harden against it.
A web server accepts HTTP requests and returns responses. Apache has been doing this since 1995. Nginx rebuilt the model in 2004 and took over the cloud. Here's how they work, how they differ, and how to pick between them.
Cybersecurity is the discipline of protecting systems, networks, and data from attack, damage, and unauthorized access. Here's what it actually covers, how attacks work, how defense works, and why every developer needs to understand it.
Infrastructure as a Service gives you virtualized servers, storage, and networking on demand without owning any hardware. You rent compute and own everything that runs on it. Here is what IaaS actually is, what it demands from you.
I exclusively used WordPress somewhere between 2008 to 2019 – if not earlier than that for me. At least eleven years. That's a good long time to
