What makes an app actually work?

1) Sign up & log in (auth)
2) Save and load data (database)
3) Accept money (payments)
4) Send updates (emails & notifications)
5) Fast and clean UI (frontend)
6) Logic runs smooth (backend)
7) Track usage (analytics)
8) Safe & stable (security)

It’s not just code.
It’s the full system behind it.

😹Hey Seniors and Juniors

No is a full sentence.

🔗 Instill Core is a universal tool for working with unstructured data.

This open-source project offers a comprehensive solution for ETL processing, data preparation for AI, and deployment of LLM models. The platform combines document, image, and video processing into a single workflow, which is especially valuable for RAG scenarios and building AI pipelines.

Instill Core can be easily integrated into existing systems via the Python/TypeScript SDK or CLI. Local execution is possible via Docker, and ready-made recipes allow you to quickly deploy PDF parsing, web scraping, or image segmentation.

😳 Meta just droped Aria Gen 2: AR glasses

Only 75 grams, foldable arms, 8 sizes, built for all-day wear (6–8 hours no problem). But what’s inside is wild:

👁 4 cameras for computer vision + 3D hand tracking
👀 Eye-tracking sensors
💓 Heart rate monitor (PPG)
🎙 Bone-conduction mic picks up your voice even on a noisy subway

And yep..everything runs locally. No cloud. Real-time eye, hand, and voice tracking with near-zero delay.

📐 80° stereo FOV and full 6DOF support. This thing maps space like a pro.

Right now it’s just for research labs, but future AR devices will build on this tech.

P.S. Phones already listen to us. In a few years, your glasses might feel your heartbeat too 🦆
