An Eight-Year-Old Polyomino Tiling Algorithm: Backtracking Search with Heuristics

2025-03-15

This article details an algorithm for solving the polyomino tiling problem. The core idea is to transform the geometric problem into a graph theory problem and use a backtracking search algorithm with various heuristics. First, the algorithm preprocesses to calculate all possible placements, constructing a bipartite graph representing all possibilities. Then, a backtracking search algorithm finds a subset of placements satisfying the conditions, optimized by heuristics such as prioritizing constrained grid points and splitting the grid. The algorithm demonstrates good generality and robustness in handling arbitrary grid shapes and polyomino sets. The author also discusses limitations and future improvements, such as transforming the problem into a SAT problem for solution.

OpenAI Bans Engineer for Building ChatGPT-Powered Sentry Gun

An engineer, STS 3D, created a robotic sentry gun controlled by OpenAI's ChatGPT API, sparking a heated debate about AI weaponization. The system, shown firing blanks in a viral video, prompted OpenAI to swiftly ban the engineer for violating its usage policies, which prohibit using its services to develop or deploy weapons. While OpenAI removed language restricting military applications last year, it maintains a ban on using its service to harm others. This incident highlights the potential dangers of AI and the need for stringent regulations on its use.

PostgreSQL FTS: 50x Speedup with Simple Optimizations

A recent benchmark by Neon showed PostgreSQL's built-in full-text search (FTS) lagging behind pg_search. However, this article reveals that Neon's benchmark used an unoptimized standard FTS setup. By pre-calculating and storing the `tsvector` column and configuring GIN indexes with `fastupdate=off`, a dramatic performance boost is achieved. Experiments on a 10-million-row dataset demonstrated a ~50x speed improvement, proving that properly optimized standard FTS can rival dedicated search engines. The article also explores VectorChord-BM25, a BM25-based extension excelling in ranking tasks.

NASA Delays Boeing's Starliner Flight to 2026

2025-06-07

NASA has delayed the next flight of Boeing's troubled Starliner spacecraft to 2026, setting back a key milestone for the vehicle intended as an alternative to SpaceX's Dragon capsule. Originally slated for a possible launch later this year, the agency is still deciding whether the next mission will carry astronauts or cargo. The delay highlights NASA's reliance on SpaceX after a botched 2024 Starliner test flight stranded two astronauts on the ISS for over nine months. Engine issues forced NASA to use a SpaceX Dragon capsule to return them, and Starliner remains uncertified for crewed missions.

Microsoft Office's Startup Boost: Faster Launch, Slower PC?

Microsoft is introducing a new "Startup Boost" feature for Office, pre-loading apps like Word and Excel when Windows starts to speed up their launch times. However, this could slow down overall computer performance. The feature will only be enabled on PCs with at least 8GB of RAM and 5GB of free disk space. While users can disable it in Word's settings or Task Scheduler, the move raises questions about whether Microsoft should prioritize improving Office's efficiency instead of relying on pre-loading. The update will initially roll out to Word in mid-May and later to other Office applications.

Structured Errors in Rust: Weighing the Tradeoffs

2025-06-01

This article explores the advantages and disadvantages of using structured errors (e.g., with `thiserror`) versus `anyhow` in Rust applications. Based on experience maintaining a large Rust web server, the author argues that custom error types, while increasing code and maintenance overhead, offer significant benefits: clearly showing all potential failure modes of a function, improving code readability and review; creating more descriptive interfaces; avoiding redundant error messages; enforcing context addition; and allowing for extra data and functionality. However, drawbacks include increased code volume, naming challenges, maintenance overhead, and potential performance concerns. The author concludes that the trade-off should be assessed case-by-case, suggesting that in large applications, the advantages of structured errors may outweigh the costs.
