• AI prompt engineering in 2025: What works and what doesn’t | Sander Schulhoff (Learn Prompting, HackAPrompt)

  Sander Schulhoff is the OG prompt engineer. He created the very first prompt engineering guide on the internet (two months before ChatGPT’s release) and recently wrote the most comprehensive study of prompt engineering ever conducted (co-authored with OpenAI, Microsoft, Google, Princeton, and Stanford), analyzing over 1,500 academic papers and covering more than 200 prompting techniques. He also partners with OpenAI to run what was the first and is the largest AI red teaming competition, HackAPrompt, which helps discover the most state-of-the-art prompt injection techniques (i.e. ways to get LLMS to do things it shouldn’t). Sander teaches AI red teaming on Maven, advises AI companies on security, and has educated millions of people on the most state-of-the-art prompt engineering techniques.In this episode, you’ll learn:1. The 5 most effective prompt engineering techniques2. Why “role prompting” and threatening the AI no longer works—and what to do instead3. The two types of prompt engineering: conversational and product/system prompts4. A primer on prompt injection and AI red teaming—including real jailbreak tactics that are still fooling top models5. Why AI agents and robots will be the next major security threat6. How to get started in AI red teaming and prompt engineering7.

• 35 years of product design wisdom from Apple, Disney, Pinterest and beyond | Bob Baxley

  Bob Baxley is a design leader who has shaped products used by billions at Apple, Pinterest, Yahoo, and ThoughtSpot. During his eight years at Apple, he led design for the online store and the App Store, and witnessed the iPhone’s transformative launch while working under Steve Jobs. A student of history turned software craftsman, Bob discovered his calling after exploring photography, filmmaking, and music, ultimately recognizing software as the most powerful creative medium of our time. Bob champions the moral obligation designers have to reduce frustration in people’s daily digital interactions.What you’ll learn:• Why design should report to engineering, not product• The “Beatles principle”—why the best products come from teams of 4 to 6, not 40 to 60• How to create design tenets vs. principles (with real examples)• The counterintuitive reason to delay drawing or prototyping as long as possible• Why software is fundamentally a medium, like film or music (not just a tool)• Why Bob “bounced off the culture” at Pinterest, and lessons from failure• The lunar landing story that teaches us about championing radical ideas• How to evaluate if a company truly values design before joining• The moral obligation of software makers to build great products—This entire episode is

• How Mercado Libre built Latin America's most valuable company: 18k engineers, 30k deploys a day, and their own fleet of planes | Sebastian Barrios

  Sebastian Barrios was the longtime head of product and engineering at Mercado Libre, the largest company in Latin America—valued at over $100 billion and home to more than 100,000 employees. There, he led a team of more than 18,000 engineers across 18 countries and oversaw an astonishing 30,000 code deployments a day. Before Mercado Libre, he founded multiple startups, including a ridesharing company that competed directly with Uber in Latin America. And at just 17, he got a personal phone call from Steve Jobs asking him to take his app off the App Store. Today, Sebastian is the SVP of Engineering at Roblox.What you’ll learn:• Why Mercado Libre operates with 95% fewer PMs than typical tech companies (and how it actually works)• How to maintain product quality with 30,000 daily deployments and distributed ownership• The weekly email system Sebastian uses to maintain alignment with leadership• How to build a culture of radical candor and direct feedback in a traditionally hierarchical region• The counterintuitive approach to product reviews that keeps 18,000 engineers aligned• How to evaluate hype cycles (crypto, AI) pragmatically while staying innovative—Brought to you by:Merge—A single API to add hundreds of integrations into your appVanta—Automate compliance.
