Brian Kernighan famously stated that debugging is significantly harder than writing a program, prompting the reflection that if one writes code in an overly clever manner, it may become difficult to debug. This idea has been paraphrased online, suggesting that writing clever code means one may not possess the necessary skills to debug it. However, the article argues that interpreting Kernighan's statement as a caution against clever coding is misleading. Rather, it highlights that the cleverness required for coding is an acquired skill,

David Fifield's article discusses the creation of a non-recursive zip bomb, a file that utilizes overlapping files within a zip container to achieve an extraordinarily high compression ratio, reported to be over 28 million (transforming 10 MB into 281 TB). This method does not rely on recursive decompression, allowing expansion after just one round. The construction uses the common DEFLATE compression algorithm and is noted for compatibility with most zip parsers. The article mentions a specific zip file called

The Union-Find data structure, commonly encountered in coding challenges like those on LeetCode, is applied in real-world scenarios, notably in Docling, a document AI toolkit that processes millions of PDFs for large language models (LLMs). Docling employs Union-Find to resolve issues with overlapping bounding boxes produced by machine learning layout models, which often result in duplicate text and fragmented tables. Machine learning layout models (e.g., YOLO, DETR, LayoutLM) predict the presence of document

The article discusses the author's journey in optimizing string-to-float conversion in Ruby after successfully enhancing float-to-string conversion using the Ryu algorithm. Initially, the author believed that optimizing the string-to-float process would yield similar performance improvements. After researching the Eisel-Lemire algorithm, which is a modern method for converting decimal strings to floating-point numbers, the author implemented it along with additional code for handling edge cases. Despite achieving successful tests and round-trip verification, the article indicates that the performance results

Docker registries like docker.io and quay.io allow users to browse and fetch OCI images and can also be operated privately. The standardized registry API enables compatibility, with the most widespread open-source implementation available. While registries generally utilize various data stores, they typically rely on S3-compatible object storage for its cost-effectiveness, persistence, and scalability. However, querying information about stored images, such as listing all repositories in a registry, is limited. The OCI distribution specification, based on HTTP, outlines
