Based on an analysis of 2,317 TV car ads, $11.3B in ad spend, 15 years of sales data, and 7 years of search trends, researchers found that informational ads increased sales for lower-priced cars under $36,000 or those with lower quality ratings, while emotional ads boosted sales for higher-priced, high-quality cars and increased searches across all price points. Emotional ads also created stronger buzz and brand interest. However, informational ads remained more effective at converting sales for cheaper cars. The findings suggest expensive products benefit most from emotional ads, while inexpensive products perform better with informational ads.
Content curation is growing in relevance, driven by user fatigue with algorithmic posts and AI-generated noise. Curation can offer a competitive edge by emphasizing taste, judgment, and cultural listening. Unlike content creation, curation builds trust by surfacing what matters, shaping narratives, and reinforcing thought leadership. For marketers, integrating curation alongside original content can deepen brand authority, expand networks, and improve campaign performance.

Bugs sneak out when less than 80% of user flows are tested before shipping. However, getting that kind of coverage (and staying there) is hard and pricey for any team.
Building a coding agent is surprisingly simple. It requires only around 300 lines of code and a loop with LLM tokens.
Python functions can be dynamically patched at runtime using `compile` and `exec` for building flexible AI bots. This can be used to generate and execute code with access to the current environment, enabling useful functionalities such as manipulating dataframes without pre-defined tools. However, this also has security risks, as malicious LLM outputs could harm the system.
Maintaining derived data, like task counts per project, is a common problem and often has complexities that arise when using caching and manual updates. Instead, "incremental view maintenance" or "differential dataflow" is a better solution. This approach involves defining desired data transformations with SQL, after which the system automatically keeps the results up-to-date.
Claude Code can be used as a design partner by creating an initial plan document, which serves as the single source of truth. The plan is a "living document," so it's constantly updated as the design gets updated, creating a collaborative design process.
When designing good APIs, avoid breaking existing code and use versioning for necessary changes. The success of an API heavily relies on the product it supports, and a poorly designed product can ruin API elegance.

react-markdown-with-mdx is a library that renders rich UI components within LLM-generated markdown using JSX. This HOC wrapper improves react-markdown to safely support JSX component tags in markdown, validating attributes with Zod. By allowing LLMs to generate JSX tags, developers can embed framework-native React components directly into AI-generated text, creating a more visually engaging and interactive UI.
Sidequest is a modern, TypeScript-based background job processor for Node.js applications. It has features like worker threads, multiple database backends (SQLite, PostgreSQL, and MySQL), ESM/CJS support, and a web dashboard for monitoring.
Claude Code is good because it's simple. It has a single main loop, simple search, and clear task management. Smaller models are great for simple tasks like parsing and summarizing, and using techniques like `claude.md` files, XML tags, and Markdown improve the outputs of Claude Code.
This dev built an online board game website with fully optional JavaScript. They used server-side rendering with SvelteKit, standard HTML elements like `summary` and `details` for interactive components, and URL parameters for managing UI state. To mimic real-time updates without WebSockets, they used the auto-refresh meta-tag.
LLMs have made a 3-month game creation effort that takes just 3 days.
AI-native design systems, like shadcn/ui, can be used to generate on-brand, production-ready prototypes by having open, composable components, token-based styling, and a registry for scaling and contextualizing design elements.
Exception safety bugs in memory management code can be prevented by reserving memory before modifying data structures to avoid data corruption during allocation failures.

While Google's new Pixel lineup doesn't look too different from the previous generation, a lot has changed under the hood. The company now believes that real evolution will come from software and connected devices rather than hardware. It is already finalizing its 2026 phones and has begun work on its 2027 lineup. The Pixel's share remains small, accounting for roughly 3% of the market.
2025.08.22·links.tldrnewsletter.com·12 min read·TLDR OpenAI is slated to become Oracle's largest customer, with the companies having struck deals for more than 5 gigawatts of computing power, an unprecedented sum. Another of Oracle's largest customers is Nvidia, which rents capacity from an Oracle cluster of H100 chips in Japan and from a data center being built in Indonesia. While Oracle's cloud business is still orders of magnitude smaller than Amazon's, there's plenty of room for growth. With all of its recent spending, Oracle recorded a negative annual cash flow for the first time since 1990. Questions about the longevity and margins of offering infrastructure to train AI models remain.
2025.08.22·links.tldrnewsletter.com·14 min read·TLDR The Chan Zuckerberg Initiative, an organization established and owned by Facebook founder Mark Zuckerberg and his wife, Priscilla Chan, has launched rBio, an artificial intelligence model trained to reason about cellular biology using virtual simulations. The breakthrough has the potential to dramatically accelerate biomedical research and drug discovery. The model uses a novel approach called 'soft verification', which uses predictions from virtual cell models as training signals instead of relying solely on experimental data. The paradigm shift means researchers can test biological hypotheses computationally before committing time and resources to costly laboratory work.

Musk and xAI had approached Zuckerberg with a letter of intent, but neither Zuckerberg nor Meta signed it. The story was revealed in court filings in a legal case between Musk and OpenAI initiated last year to stop the startup from converting to a for-profit entity.
Alpha School is a teacherless, homeworkless, K-12 private school in Austin, Texas. Its students have been testing in the top 0.1% nationally. They learn through self-directed coursework with AI tutoring apps for two hours a day, spending the other four hours of the school day in 'workshops' where they learn things like how to run an Airbnb or food truck, manage a brokerage account or Broadway production, or build a business or drone. Alpha School's new product, Timeback, is aimed at scaling Alpha School's concepts and results and giving students their childhoods back. Timeback will be free to everyone once it's released.
