The content discusses the desire to delay message processing in Kafka, which traditionally processes messages immediately upon production. This immediate processing can be problematic when a delay is needed, such as sending notifications after a certain period, retrying third-party API calls, scheduling future tasks, or staggering microservice calls. While Kafka is designed for high throughput and does not offer a built-in way to delay messages, a custom solution can be developed using Kafka's retry mechanism. By deliberately causing failures during message processing, Kafka can

In this piece, Marcin Wichary reflects on his evolving relationship with typography, particularly focusing on the font Gorton. Initially, during his first trip to New York City in 2007, Wichary documented iconic fonts like American Typewriter and Helvetica, but overlooked Gorton, which is ubiquitous yet unremarkable in appearance. It wasn't until 2017, while researching for a book on the history of typing, that he discovered Gorton’s peculiar characteristics. He describes the font as

The Crunchy Data Warehouse is a next-generation, Postgres-native data warehouse that offers enhanced capabilities for handling event data from various devices. While PostgreSQL effectively manages individual and batch event data, it faces limitations for certain scenarios that require more efficient analysis, such as automated archival to cost-effective storage in a format conducive to large-scale analytical queries. To address these limitations, two open-source PostgreSQL extensions, pg_parquet and pg_incremental, have been developed. These enable the automatic export of specified time

Mathematicians have recently demonstrated that any sofa larger than a specific size will become stuck when moving through a hallway corner, which presents a complex geometric problem known as the "moving sofa problem." This issue, first framed by Leo Moser in 1966, involves determining the maximum area of a two-dimensional shape that can navigate through an L-shaped hallway of unit width without getting stuck at the corner. While smaller shapes like a square or semicircle can easily maneuver through, larger, more complex shapes

BetterHTMLChunking is a Python library designed for intelligent HTML segmentation that constructs a DOM tree from raw HTML to extract content-rich areas effectively. It is particularly useful for content analysis and large language model (LLM) processing. The library generates structured, size-limited segments from HTML documents while maintaining semantic coherence and respecting size constraints. Unlike plain-text or token-based chunking strategies which focus on token limits, BetterHTMLChunking preserves the HTML DOM structure, optimizing chunk boundaries based on the length of text
