02ARTICLES & TUTORIALS

LESSONS LEARNED FROM A SUCCESSFUL RUST REWRITE

This developer rewrote a C++ codebase to Rust and, while it was mostly successful, there were still some interoperability challenges. Using raw pointers and unsafe blocks in Rust proved to be a major source of undefined behavior that was often undetected by the compiler and required tools like Miri for validation. The Rust borrow checker and the lack of native arena allocators created challenges when managing memory resources.

USECONTEXTSELECTOR: SPEEDING UP REACT APPS WITH LARGE CONTEXT

Using large contexts in React applications can lead to performance problems, as changing a single value in a large context can cause unnecessary re-renders of components. There are several proposed solutions: splitting components, splitting contexts, and using state management libraries. The `use-context-selector` library, which this article dives deeper into, provides a way to optimize performance by selecting and re-rendering only the parts of a context that have changed.

03OPINIONS & ADVICE

WHY SPRINTS ARE TAKING THE JOY OUT OF BUILDING SOFTWARE

Sprints are a core element of Scrum, but can be detrimental to software development. Sprints are too rigid, prioritizing processes over individual creativity and customer value. Instead, allow teams to be more flexible about timelines and give engineers more autonomy in their work.

CREATING A LLM-AS-A-JUDGE THAT DRIVES BUSINESS RESULTS

LLM-as-a-judge systems have LLMs evaluate LLM responses in order to make LLM applications better. This article outlines seven steps to building a great LLM-as-a-judge system: find a “Principal Domain Expert”, create a diverse dataset, have the expert review and critique the data, fix errors, build the LLM judge, perform error analysis, and create specialized judges if needed.

CHAIN-OF-THOUGHT CAN REDUCE PERFORMANCE ON TASKS WHERE THINKING MAKES HUMANS WORSE

Chain-of-thought (CoT) prompting LLMs reduces performance in cases where thinking also negatively affects human performance. Experiments across three task categories where thinking harms human performance (implicit statistical learning, visual recognition, and classification with exceptions) consistently demonstrate that CoT reduces model accuracy. This suggests that model reasoning, like human deliberation, can lead to detrimental outcomes when applied to certain tasks.
