🚀 Tech watch week 37
on September 11, 2025
This week's Watch highlights open source projects, applied research in AI and the web, and practical advances in PHP frameworks and development tools.
🎨 Prompt Engineering Framework
The Grace repository explores building a strongly typed prompt engineering framework in Haskell. It highlights functional approaches to designing robust systems where prompts become testable and composable entities. A step closer to industrializing AI uses. 👉 github.com/Gabriella439/grace
🤖 Multi-Agent Systems in Laravel
Inspector presents a practical demo for building multi-agent systems in Laravel. The article shows how to orchestrate cooperative AI with simple code, paving the way for advanced applications integrated directly into the PHP ecosystem. 👉 inspector.dev/building-multi-agent-systems-in-laravel-a-practical-demo
🔢 Character counter and uniqueness
Gary Hockin shares a technical insight into string counters and the importance of binary representations. An educational demonstration that illustrates how a coding detail can have real-world implications for software reliability. 👉 linkedin.com/posts/gary-hockin-9b06863a_3v4lorg-activity
🏛️ DDD and Symfony 7
Mykola Vantukh explains how to implement Domain-Driven Design in Symfony 7 using a clean architecture, reinforced by Deptrac. The article highlights best practices for maintaining clear boundaries between domains, applications, and infrastructure. 👉 dev.to/mykola_vantukh/ddd-in-symfony-7-clean-architecture
🌀 Distributors in functional programming
MorphismTech publishes a post on distributors, a mathematical generalization of functors. The text illustrates how these theoretical concepts can be used to structure and reason about complex data transformations. 👉 github.com/morphismtech/distributors
👁️ Vision-Language World Model
Pascale Fung introduces a vision-language model capable of reasoning on multimodal representations to create “world models”. A crucial step towards systems capable of anticipating and planning in hybrid text/image environments. 👉 linkedin.com/posts/pascale-fung-vision-language-world-model
🧬 SCILLA
One thread highlights SCILLA, a framework for simulating complex systems inspired by physical laws. The tool allows for modeling multi-agent interactions and could find applications in AI research as well as in gaming. 👉 x.com/ponceto91/status/1963848330082963792
🗄️ SQLite Vector Extension
Philipp Schmid points out that SQLite now has a vector extension. This opens up interesting possibilities for running vector searches directly in a lightweight database, without relying on massive infrastructures like FAISS or Milvus. 👉 linkedin.com/posts/philipp-schmid-sqlite-vector-extension
✂️ Optimized string splitting
Daniel Lemire illustrates how to efficiently split a long string into subsequences using implementation tricks. This optimization, when applied at scale, can improve the performance of tools handling massive text. 👉 x.com/lemire/status/1964779187136233964
🎥 Veo3 on Replicate
Replicate announces the availability of Veo3, an advanced video generation model. Accessible via API, it opens new possibilities for integrating generative video content creation into automated workflows. 👉 x.com/replicate/status/1930774344902541564
🎨 Relative colors in CSS
JoliCode offers a clear article on the use of relative colors in CSS. These new features simplify the management of themes and palette variations by making styles more expressive and maintainable. 👉 jolicode.com/blog/les-couleurs-relatives-en-css
🔎 Conclusion
This week highlights a convergence between theoretical research (distributors, DDD), practical engineering (Laravel multi-agents, SQLite vector), and creative innovation (Veo3, CSS relative colors). A perfect illustration of the ongoing dialogue between fundamental concepts and concrete applications.
