WAN Show: Guinness World Records, Pi, and Bike Paints

The World's Largest Pi Calculation

Linus and Luke discuss the achievement of a Guinness World Record for calculating the most accurate value of pi to 300 trillion decimal places.

• Infrastructure Challenges: The project faced significant hurdles, most notably an unreliable power grid at the lab and cooling system failures that plagued operations.
• Verification Process: Contrary to doubts, the record was validated using BBP (Bailey-Borwein-Plouffe) extraction, allowing for precise chunk verification rather than constant full-calculate reruns.
• Hardware Persistence: The project utilized high-speed PCIe storage arrays originally designed for a different venture, keeping the hardware working on difficult workloads.

DIY Projects & Tech Mishaps

The Bike Paint Saga

Linus shares his arduous journey of painting a motorcycle.

"It’s a combination of things because I'm ambitious slash foolhardy sometimes."

• The process involves over 11 layers of paint, including candy colors and pearl coats, which has proven difficult to maintain without defects.
• He encountered major issues with masking tape peeling off fresh paint, forcing him to restart sections.

Home Infrastructure

• Power Backup: Luke discusses his plans for a DIY UPS (Uninterruptible Power Supply) system at his home, scaling from small proof-of-concept tests to a larger, outdoor battery storage solution.
• Software Frustrations: A humorous but painful technical session involving login loops on an LG TV while trying to set up Sunshine and Moonlight for gaming.

Industry Insights

• VPN Secure Controversy: The team highlights the unethical business practice of a company canceling lifetime subscriptions after an asset-only acquisition. Linus warns users to abandon the service entirely rather than accept discounts.
• Philips Fixables: A praised partnership with Prusa that enables users to 3D print replacement parts for appliances—a massive win for the Right to Repair movement.
• Podcast Metrics: A deep dive into the industry-wide resistance to transparent play counts, suggesting many smaller podcasts rely on "old media" metrics to inflate ad value.
