CarStocks

Your stock watchlist on the car’s Android Auto screen, with price and day, week and month change for up to ten tickers. Tap one and it reads the quote aloud through the car speakers. It gets onto the car screen by registering as a media app, which is also why it isn’t on the Play Store. It’s a free APK you install yourself.

Lumea Vidฤƒ โ€” The Void World

An ongoing English translation of my father Constantin Marghitoiu’s philosophical treatise. “Vidฤƒ” means void or vacuum in Romanian โ€” the work explores the nature of perception, consciousness, and the structure of experience through a systematic framework built across two parts and five chapters. Originally written in Romanian, the full manuscript runs approximately 90,000 words. Translation is currently ~16% complete, with Part I, Part II and Chapter 3 available in English alongside the full Romanian original.
