Technical notes

This page gathers technical reflections on structure, simplicity, autonomy and long-term system sustainability.

Technical articles on web development, software architecture and the design of simple, durable and autonomous systems.

This is not a news feed, and not a collection of tutorials. It is a space to document a way of designing systems: clear, predictable, and maintainable over time.

For a more visual approach, some of these topics can also be explored through interactive experiences and animated visualizations, designed to show how these mechanisms work beyond traditional articles.

Why this section exists?

Palks Studio designs business systems as well as structured technical tools. Behind every system and every tool are architectural decisions and technical trade-offs involving simplicity, dependencies, readability, and autonomy.

These notes explain those decisions, define principles, and make the design logic explicit.

Factur-X EN16931: why your invoice is probably not compliant

PDF/A-3, XSD, Schematron: three compliance levels most e-invoicing solutions fail to fully validate.

Other technical notes explore architectural decisions, tools and methods actually used by the studio when designing and deploying its systems. They explain the reasoning behind these choices, the trade-offs involved and the principles that help build simple, reliable and maintainable solutions.

Software Architecture

• Useful vs. Accidental Complexity A reflection on the complexity that strengthens a system, and the kind that slowly makes it fragile and unreadable. ›
• Real-Time and Complexity Why real-time can unnecessarily complicate simple systems. ›
• Static Website Architecture Performance, SEO and controlled structure. ›
• Local Chatbot Architecture Control, logic and predictable systems. ›
• Application Security Authentication, sessions, APIs, and architecture for building more secure and resilient applications. ›
• Technical SEO HTML structure, semantic markup, accessibility, and architecture to help search engines crawl and understand your website. ›

Tools & Development Environment

• VS Code Environment Local control and project stability. ›

Electronic Invoicing

• Paid Invoices Why paid invoices should never be overlooked. ›
• Factur-X EN16931 Compliance Understand why a valid invoice is not necessarily compliant with PDF/A-3, XSD, and Schematron requirements. ›
