Welcome to Tech Beat, your daily read on what's moving in the world of technology.
First up, a question that trips up a surprising number of developers: why does SQLite hold onto disk space even after you delete data? The answer lies in how SQLite manages its internal page structure. Deleting rows marks pages as free, but the database file itself doesn't shrink unless you explicitly run the VACUUM command. It's a deliberate design trade-off — speed over tidiness — and understanding it can save you from some genuinely confusing storage headaches.
Shifting to the AI research front, Facebook's team has published work suggesting that pixel embeddings can outperform dedicated vision encoders when it comes to unified image understanding and generation. The project, called TUNA two, challenges a long-held assumption that specialized encoder architectures are the right foundation for multimodal models. If the results hold up to broader scrutiny, it could meaningfully reshape how the next generation of vision-language systems gets built.
And finally, something a little different — Museum Speelklok in Utrecht has been drawing fresh attention online. The museum is dedicated entirely to self-playing musical instruments, from elaborate street organs to ornate music boxes. It's a reminder that automation in music predates the digital age by centuries, and that the human fascination with machines that perform is anything but new.
