Methodology

How we work when the answer is not settled yet: approach, architecture decisions and the trade-offs behind them. These pieces describe method rather than outcome, so you can follow our reasoning and carry it into your own project.

How large can a 3D model be in the browser? How large can a 3D model be in the browser? A 3D model in the browser has two budgets: transfer and GPU memory. Textures usually decide whether it still runs smoothly on a customer's phone. Methodology •9 min 09/14/2026 Replacing a legacy system: step by step, not on one cut-over date Replacing a legacy system: step by step, not on one cut-over date How to replace a grown legacy system module by module: a router in front of it, an order derived from dependencies, and a parallel run with a comparison. Methodology •7 min 09/14/2026 Why AI features fail in practice: seven stages where errors arise Why AI features fail in practice: seven stages where errors arise A wrong AI answer almost always has an address. Knowing the seven stages of an AI feature lets you find the fault before anyone swaps the model. Methodology •9 min 09/14/2026 Room check and level of detail: does it fit the room, and when does AR help? Room check and level of detail: does it fit the room, and when does AR help? Whether an enclosure fits the hall can often be calculated without a camera. When a room check is enough, how detailed the 3D model must be, when AR helps.

Datenbäume sind die häufigste Ursache für parametrische Modelle, die plausibel aussehen und falsch sind.

Es sind Indexpflege, Evaluation und der Betrieb, und diese drei stehen in keinem Angebot, das nur die Entwicklung beziffert.

Ab welcher Variantenzahl sich das umkehrt, und die Fälle, in denen es das nie tut.

It is what makes agents reliable. Methodology •3 min 06/25/2026 F-RAG (RAG-Fusion): how it differs from plain RAG F-RAG (RAG-Fusion): how it differs from plain RAG RAG-Fusion runs several query variants and fuses the results with reciprocal rank fusion. Better recall, some drift risk.

A sober overview. Methodology •3 min 06/25/2026 From photo to printable part: what image-to-3D can and cannot make From photo to printable part: what image-to-3D can and cannot make Image-to-3D makes a pretty mesh, not a manufacturable part. A printable part needs geometry a slicer trusts: watertight, scaled, tolerant. Methodology •3 min 06/25/2026 Query decomposition and the advanced-RAG toolkit: match the method to the failure Query decomposition and the advanced-RAG toolkit: match the method to the failure Query decomposition, HyDE, RAG-Fusion, GraphRAG each fix one failure. The sophisticated 2026 RAG knows when to use none. Methodology •4 min 06/25/2026 Prompt engineering vs context engineering: not a rebrand, a change in what you optimise Prompt engineering vs context engineering: not a rebrand, a change in what you optimise Prompt engineering words one instruction. Context engineering designs the whole payload the model sees, under a token budget.

Reliability against flexibility. Methodology •2 min 06/25/2026 Vibe coding: where it helps, where it bites Vibe coding: where it helps, where it bites Vibe coding is a tool, not a method. The line runs between throwaway code and software that ships to production.
