Why Braille Matters and Problem Framing

Today Quincy Larson interviews Alison Co and Cindy Cui, two university students who won the NW Hacks hackathon with their tool that helps people who are losing their vision learn to read Braille. He met them when GitHub invited them to their big San Francisco conference, GitHub Universe to present their project.

Alison Co is a software engineer who's graduating Fall 2026. She's among the prestigious Major League Hacking Top 50 hackers. She's interned at Hubspot and will soon start interning at Rippling.

Cindy Cui is a software engineer who's graduating Spring 2026. She's interning as a backend developer at Shopify. She also teaches violin and holds the prestigious Level 10 Violin certification from the Royal Conservatory of Music.

We talk about: - Tips for securing good internships - How they use AI as university students and as devs, and its limits - How they built their winning hackathon project to help people losing their vision learn to read braille

5. Learn about the eccentric designer Luigi Colani and his biomorphic designs that imitate nature. This video essay dives into the German designer's life history and his body of work. Why were his designs so broadly disliked by the design establishment? In what ways was he ahead of his time? How did he influence the development of cameras, or design a gas-powered car that got 130 miles to the gallon? I learned a ton from this and you will to. 30 minute watch: https://www.youtube.com/watch?v=SVo7H3EheMY

6. Today's song of the week is Leon Ware's 1982 classic "Why I Came to California". I love the positive energy of the song, the brass blasts, and the duet vocals. I thought it'd be perfect since I met today's podcast guests in California when they were visiting from Canada. https://www.youtube.com/watch?v=k1gwc9HJARU
