4. AI’s top startups are barely publishing their research
⭐ 493 💬 253 👤 YeGoblynQueenne 🔗 Discuss on HN
Leading AI startups including OpenAI, Anthropic, and others publish very little of their research in peer-reviewed academic journals. The article examines how this trend undermines scientific reproducibility, slows open progress, and creates an opaque landscape where breakthroughs emerge primarily through product launches.
5. Azulejo
⭐ 21 💬 3 👤 Amorymeltzer 🔗 Discuss on HN
Azulejos are the traditional Portuguese and Spanish glazed ceramic tiles known for their intricate geometric and figurative patterns. Dating back to Moorish Spain in the 8th century, they became a defining element of Iberian architecture — adorning churches, palaces, and public buildings throughout the region.
6. The coolest use for the Vision Pro
⭐ 699 💬 268 👤 robbiet480 🔗 Discuss on HN
A developer used Apple Vision Pro as an ultra-high-resolution display wall, projecting a multi-monitor setup directly into a room for spatial computing. The experiment demonstrates an unconventional but visually impressive application of the headset’s inside-out camera and spatial mapping capabilities.
