Researchers at Tsinghua University introduced a groundbreaking algorithm in 2025, surpassing Dijkstra’s algorithm, which had been the go-to method for solving the single-source shortest path (SSSP) problem for decades. Dijkstra's algorithm has a complexity of O(m + n log n), relying heavily on sorting operations within a priority queue. The Tsinghua team, led by Professor Duan Ran, achieved a theoretical runtime of O(m · log^(2/3) n) by circumvent

The text discusses the evolution of web server architecture and performance optimizations, focusing on the increasing need for high-capacity servers around the turn of the century, particularly related to the C10k problem. Initially, web servers handled requests by pre-forking processes for efficiency, as creating a new process for each request was common at the time. As technology evolved, the use of threads became prevalent, followed by techniques like poll() and select() to minimize the overhead of process/thread creation and context switching

The content discusses the principle that all real-world variables are correlated, which has significant implications for statistical theory, particularly concerning null hypothesis significance testing. It highlights the idea that non-zero correlations exist between measured variables, even if they seem independent, and that these correlations are not mere artifacts of sampling error. This observation challenges the validity of the null hypothesis, suggesting that it will always be rejected with sufficiently large datasets, meaning a failure to reject it only indicates insufficient data rather than support for a theory. The piece

The thoughtbot team is currently engaging with clients in a live collaboration, inviting questions from viewers. They discuss challenges related to logging sensitive information during network requests, particularly when dealing with free text rather than parameters. Since regex filtering has limitations, especially for unstructured data, they recommend using named-entity recognition (NER) to identify sensitive information such as personal details. The tool, Top Secret, combines regex and NER to effectively filter this information. In scenarios like chatbots that handle user data, it's

On August 21, 2025, Jon Davis, Jen Simmons, and Tim Nguyen introduced the new `random()` function in CSS, which allows developers to generate random values directly within stylesheets—eliminating the need for JavaScript. The function takes three arguments: `random(min, max, step)`, enabling users to specify a range for random numbers and optionally define a step for rounder results. This function can be used for various purposes such as randomizing animation delays, layout positions

The recent release of uv version 0.8.13 introduced a new experimental command called `uv format`, which simplifies Python code formatting by integrating it directly into the uv toolkit. This feature eliminates the need for multiple tools, as it utilizes Ruff's formatter to ensure consistent code styling. To use this command, make sure you are updated to uv 0.8.13 or later, and then format your project easily by running `uv format`, similar to the `ruff format` command. You

Hillel Wayne discusses the Python feature `__subclasshook__`, which allows Abstract Base Classes (ABCs) to determine what counts as a subclass, even if the subclass does not specifically acknowledge the ABC. He shares a previous use case of this feature to create non-monotonic types, such as classifying objects that lack an `__iter__` method as `NotIterable`. With the introduction of pattern matching in Python 3.10, Wayne explores the potential for ABCs

As a core database engineer at QuestDB, I frequently work with performance-sensitive code that handles large datasets. Recently, I faced a situation where an AI-suggested optimization for the `calculate_array_shape` function, which is essential for reading Apache Parquet files and determining array dimensions, actually worsened performance. This experience underscored the significance of benchmarking real-world performance rather than depending on theoretical enhancements. The initial version of `calculate_array_shape` was simple but inefficient in terms of CPU usage

In a recent post on meyerweb, the author delves into the use of the infinity keyword in CSS for manipulating various text properties, building on previous discussions about font sizes and line heights. The exploration extends to properties such as text indents, letter spacing, and word spacing, which can lead to interesting results, particularly regarding horizontal overflow and visible text behavior. While the visual output remains consistent across different CSS adjustments, differences emerge when examining computed values in browsers. Safari and Firefox show internal consistency
