Tech & Automation
Tutorials, engineering notes and industry insight, from Git to PLCs.
Scripting for IT Support (PowerShell & Bash)
Every support engineer hits a ceiling doing things by hand. Scripting is how you break through it, and you only need two shells to start.
ITSM & the Service Desk (ITIL)
The service desk is the most underrated team in IT. Run it as a service, not a switchboard, and it quietly makes the whole organisation better.
Building an Online Course
Most online courses fail not because the teaching is bad, but because they were never designed to be finished. Here is how to build one that is.
Recording Great Video Tutorials
The gear matters less than you think. Here is what actually separates a tutorial people finish from one they abandon.
Hybrid Agile + Waterfall Delivery
Most organizations are neither agile nor waterfall. Stop apologizing for it and start designing for it.
Understanding the Roles: Software Engineer vs. Data Engineer vs. Cloud Engineer vs. AI Engineer
The fields of software engineering, data engineering, cloud engineering, and AI engineering each play unique roles in technology development and deployment.
A Comprehensive Guide to Hierarchical Planning in Production and Supply Chain Management
Production and supply chain management require a structured, multi-level approach to planning that ranges from strategic decisions to daily scheduling.
Project Budgeting & Cost Control
Why the question "how much have we spent?" is the least useful thing you can ask about a project budget - and what to ask instead.
Machine Learning for Analysts
You do not need a PhD to build a useful model. You need to frame the problem, respect the test set, and know when to stop.
Data Warehousing & Analytics Engineering
The warehouse stopped being a place to store data and became a place to write code - and that single shift created a whole new craft.
Cloud Cost Optimization (FinOps)
Cloud bills don't spiral because engineers are careless. They spiral because the cloud removed every brake that used to slow spending down. FinOps is how you put the brakes back without killing the speed.
Cloud Security & IAM Deep Dive
The firewall is not your perimeter anymore. A credential is. Once you accept that, cloud security stops being a checklist and becomes a single discipline - getting identity right.
The Difference Between Front-End and Back-End Developers: A Comprehensive Guide
Front-end vs back-end developers: what each one does, the tools and languages they use, and how they work together to build web applications.
CI/CD Pipelines in the Cloud
A deploy that takes a weekend and a wiki page nobody trusts is not a release process — it is a liability. Here is how cloud pipelines turned shipping software from an event into a non-event.
Cloud Security Posture Basics
The cloud did not make you less secure. It made misconfiguration faster, more visible, and one click away from the entire internet. Here is how to see your own account the way an attacker already does.
Zero Trust Architecture Explained
The perimeter was never a wall. It was an assumption, and assumptions are exactly what attackers exploit.
Digitalizing SME Operations End-to-End
Small businesses do not fail to go digital because the software is too hard. They fail because they buy tools before they understand their own work. Here is the order that actually works.
Comprehensive Guide to Setting Up Ubuntu on Your Local Machine | 02x00.06-02
Setting up a robust coding environment on your local machine is essential for efficient software development.
KPIs & Dashboards for Operations
Most operations track dozens of numbers and steer by none of them. The fix is not more data or a prettier dashboard - it is the unglamorous discipline of choosing the few metrics that actually change what you do.
Find Your Perfect IT Job Based on Your MBTI Personality Type
Match your MBTI personality type to an IT career: from ENTJ IT managers and INTP programmers to ESTP support analysts and ISTP QA testers.
AI & MLOps for Industrial Engineers
Most industrial machine-learning models work beautifully in a notebook and die on the laptop they were born on. Here is why that happens, and what MLOps actually fixes.
Introduction to Vi | 02x00.03-03
Vi is a powerful and efficient text editor that has been a standard in Unix and Unix-like operating systems for decades.
Introduction to Emacs | 02x00.03-02
Emacs is not just a text editor; it is a powerful tool that can revolutionize the way you interact with your computer.
Citizen Science: Unlocking the Power of the Everyday Person in Tech Discovery
Citizen science lets everyday people drive discovery, from Galaxy Zoo to bird counts. How it works, why it matters and how you can get involved.
