Built a new toy: KeyCast Lower Thirds—Electron + React app for instant lower-third graphics

I’ve been obsessed with how Japanese TV shows composite animated lower thirds over live footage—those layered graphics that somehow feel both playful and precise. To learn the craft, I built KeyCast Lower Thirds, an Electron + React app that mimics broadcast workflows without the usual control-room headaches. You get a clean operator panel, a fullscreen kiosk output, and real-time sync between the two. Toggle text, colors, placements, and animated logos instantly, then ship the feed straight into OBS or an ATEM via chroma key or alpha workflows. In practice, it’s become my sandbox for experimenting with conference graphics, live presentations, […]

Symfony’s Experimental AI Store: A Deep Dive into InMemoryStore

Symfony is steadily evolving into a modern AI-enabled framework—and one of its most exciting experimental additions is the symfony/ai-store component. This new package lays the foundation for semantic search, context injection, and Retrieval-Augmented Generation (RAG) workflows directly inside PHP applications. What Is Symfony AI Store? The AI Store component is a low-level abstraction for managing vector stores. In simpler terms, it helps store documents as embeddings (numerical vectors) and retrieve them later using similarity search. This is crucial in RAG scenarios, where an AI agent dynamically pulls relevant facts from a custom knowledge base before answering user queries. This component […]

My First Successful Fine-Tuning of an LLM on Custom Symfony + Chameleon Knowledge

After several trials and experiments, I’ve finally completed my first successful fine-tuning of a LLaMA-based model using my own real-world internal IT documentation. This project fine-tunes a 3B parameter model to understand and respond to Symfony command usage, Chameleon CMS workflows, and developer issues like rsync errors or Xdebug debugging failures. The result is now publicly available on Hugging Face: kzorluoglu/chameleon-helper Setup Overview I used the excellent Unsloth Synthetic Data Kit and trained the model on a curated dataset of 32 instruction-based Q&A pairs, written in natural German developer language. Instead of the usual instruction/input/output JSON format, I opted for […]

Rückblick: Symfony PHP Meetup Basel – 12. April

Gestern war ich beim Symfony PHP Meetup in Basel.. 1️⃣ hurl – ein leichtes Testing-Tool in Rust, für einfache API-Tests. 2️⃣ Ein Plugin zur Absicherung von JSON-Requests – mi einem Symfony-Plugin zur Absicherung eingehender JSON-Requests. Besonders interessant war: Die Flow-Erklärung, Der Einsatz von Compiler Passes, Und warum das Event nicht auf der Request-Ebene, sondern auf der Controller-Ebene ausgelöst wird – eine bewusste Designentscheidung für bessere Kontrolle und Trennung. 3️⃣ Symfony Clock Component – mit einem kleinen Live-Demo. Sie eignet sich ideal für testbare zeitbasierte Logik und wurde als internes Werkzeug für künftige Entwicklungen empfohlen. Danke an alle Speaker & PHP […]

Resolving Laravel SQLite Locked Error in PhpStorm with WSL2

When working with SQLite databases stored in WSL2 and accessing them via PhpStorm, you might encounter the following error: Error encountered when performing Introspect schema main: [SQLITE_BUSY] The database file is locked (database is locked) This issue arises due to SQLite’s file locking mechanisms, which are not fully compatible with WSL2’s file system when accessed through tools like PhpStorm. Problem When you drag and drop an SQLite file from the WSL2 folder into PhpStorm’s Database tab, PhpStorm generates a default connection URL like this: This URL does not include parameters to prevent locking issues. As a result, SQLite encounters file […]
