While Postgres 17 offers huge improvements, most users stick with older versions due to the perceived stability of the database and the challenges of upgrading. Major version upgrades can be complex and require extensive planning, data migration, and testing, especially for large production databases. However, delaying upgrades inevitably leads to technical debt. There is now a tool available called PG Versions that can help visualize the new benefits of upgrading earlier rather than later.
Evals, a new testing paradigm for AI-native development, are similar to end-to-end tests. They assess the quality of AI output using automated checks, human judgment, and AI-assisted grading. Vercel's frontend-generating AI product v0 is built on eval-driven development.
There are a few issues with system evaluation practices, like in cases where metrics with similar names yield vastly different results, implementation bugs lead to inflated scores, and incorrect predictions improve the score. Developers need to be careful when choosing metrics and understand what a metric truly measures to make sure it's implemented correctly.
Unit tests can serve as living documentation within the code itself, explaining how code behaves, staying in sync with code changes, and covering edge cases.

This blog post goes over the end-to-end process of implementing a drag-to-select functionality in React, with code examples and challenges faced along the way. For example, one of the challenges of implementing this functionality was representing user interactions when handling drag selections in multiple directions. To fix this, create a DOMVector class, a custom data type that captures both magnitude and direction, which removes the need for complex state management.
When building a Python backend for a transcript optimizer app, this developer used FastAPI, SQLmodel, and Whisper for transcript generation, along with LLMs for text optimization and quiz generation. GPT4o-mini and Claude 3 Haiku were cheaper for this task, especially when combined with chunking input text and creating pipelines to handle complex transformations. SQLite was used as the database solution.
Canva's collaboration team implemented real-time mouse pointers to make its whiteboard product better. Initially, they utilized a backend-centric architecture using WebSockets and Redis, which scaled to support hundreds of thousands of simultaneous users, but had limitations in update rate. Recognizing these limitations, the team migrated to a WebRTC-based architecture, which allowed direct peer-to-peer communication between clients, reducing latency and improving scalability.
This is a detailed retrospective from a former Palantir employee who spent eight years at the company. Palantir is unique in that it has "forward deployed engineers" (FDEs) who work directly with clients and engineers who work on the core product (away from clients). The company also has a "messianic cult" culture, characterized by intellectual intensity and a focus on achieving real-world outcomes, and deals with the moral complexities of working with clients in the "grey areas" of government and defense.
Success in programs or applications due to flawed tests or incorrect models can lead to unexpected real-world failures. Even if tests pass and/or a model seems to work, it's still useful for developers to be “suspicious” by testing both "happy paths" (ideal scenarios) and "sad paths" (error handling).
React Server Components can cause a "server waterfall” problem, which is when a component's data fetching causes a delay in rendering due to dependencies. However, this problem also exists on the client-side. The benefit of server-side waterfalls over client-side waterfalls is that the server environment offers more control over the network and caching.

The way data is organized in memory (data layout) can impact a program's performance. Choosing the right data layout, such as Array of Structures (AoS) or Structure of Arrays (SoA), can optimize cache line access and leverage vectorized instructions (SIMD) for faster execution. SoA, for example, can be much faster for reading operations, especially when combined with lightweight compression techniques like frame-of-reference encoding.
This article compares different methods for storing data in web browsers: Cookies, LocalStorage, IndexedDB, OPFS, and WASM-SQLite. Each method is analyzed for their features, limitations, and performance in various scenarios, including write and read latency for single and bulk operations.
Iterators and range objects are different in Python. While both are considered "lazy iterables" as they compute values on demand, they differ in their underlying mechanisms. Iterators are stateful, meaning once an item is consumed, it's gone. Range objects are not iterators - they are "lazy sequences" that can be looped over repeatedly without exhausting their values.
SMURF (Speed, Maintainability, Utilization, Reliability, and Fidelity) is a framework for better testing. Prioritizing one factor can have implications for others, so it's best to have a holistic approach when writing tests for applications.
The pursuit of unicorn status by venture capital funds has led to the creation of companies that, while initially seemingly harmless, become detrimental at scale. This is because the need for massive growth drives companies to exploit resources and disrupt markets. The recent decline in venture capital funding offers an opportunity for more non-hyper growth companies that are still sustainable businesses.
