The Dargslan Tech Blog — Linux, DevOps, Cloud & Cybersecurity
Welcome to the Dargslan Tech Blog — long-form, hands-on articles for engineers who run real
systems in production. We publish every week on Linux administration, DevOps tooling, cloud architecture,
cybersecurity, Python automation, Windows Server, and the practical day-to-day skills that separate junior
sysadmins from senior platform engineers. Every post is written by working professionals, includes copy-pasteable
code and configuration files, and is updated whenever upstream tools release breaking changes.
What you will find here

- Security deep-dives: SELinux policy writing, Wazuh and OSSEC tuning, Linux auditd, fail2ban, ModSecurity, and OWASP-aligned secure coding patterns.
- Cheat sheets & quick references: Printable PDF cheat sheets for Vim, tmux, Docker, kubectl, systemd, awk, sed, ss, journalctl, and dozens of other tools — free to download.
- Daily IT tip: A new tip every weekday — one Linux command, one cloud concept, or one real-world troubleshooting trick. Subscribe via RSS or email.
- Tech news & releases: Curated coverage of Linux kernel releases, Kubernetes versions, AWS/Azure/GCP service launches, CVE alerts, and major open-source project updates.
Why read the Dargslan blog
There is no shortage of tech blogs on the internet, but most fall into one of two traps: shallow listicles written
by people who have never touched the tools, or 30-page corporate whitepapers designed to sell a product. Our
articles sit in the middle — long enough to actually solve your problem, short enough to read with a coffee, and
always grounded in working examples you can run in your own terminal. We don't write filler, we don't gate content
behind email forms, and we never publish AI-generated slop without expert review.
Our writers come from a sysadmin, SRE, and DevOps background and have shipped production systems for fintech,
healthcare, telco, and SaaS companies across Europe and North America. When you read a tutorial here, you're
reading what someone actually did at 2am during an incident — not a sanitized vendor case study.

daily IT tip for a steady stream of practical knowledge. If long-form learning is more your
style, our companion eBook library covers every topic from this blog in 200-500 page depth,
with downloadable code repositories and lifetime updates.
