Research indicates that a father's lifestyle—specifically his diet, exercise, and stress levels—can be encoded in the RNA of his sperm and epigenetically influence his offspring's development. Traditionally, it was believed that sperm primarily delivered DNA to the egg, with no further contribution from the father. However, studies over the past two decades have shown that sperm may carry additional information that can impact the genomic activity of the embryo. This emerging understanding may alter traditional views of heredity, suggesting that paternal

In the article by Aaron T. Grogg, published on December 27, 2025, the author highlights the longstanding role of JavaScript (JS) as a crucial tool for web development, particularly in enhancing user experiences beyond what HTML and CSS can offer. However, as HTML and CSS evolve, Grogg argues for a shift towards reducing JS usage for tasks that can now be handled by native HTML or CSS. This reduction can lead to lighter web pages, faster load times, and allow JS

This post is part of a series focused on implementing a programming language in Rust, specifically addressing the topic of name resolution. After the process of desugaring, the program is left with an abstract syntax tree (AST) represented as `Ast<String>`, which is not yet suitable for type inference. Name resolution will transform this into `Ast<Var>`, preparing it for type checking by clarifying what the names in the program represent. The importance of naming in programming is emphasized, as names help

Alex Gaetano Padula reflects on the development of TidesDB, an embeddable key-value storage engine in C, which has evolved through multiple revisions to its current version, 7.0. His journey involved extensive experimentation and learning about storage engines, LSM-trees, and system failures. Rather than imitating existing technologies, he aims to understand storage systems from the ground up, focusing on optimization for modern hardware. The development process emphasizes obsessive curiosity, resulting in innovations like primarily lock-free

In a recent blog post, Ploum discussed the controversy surrounding Pixelfed's practices, particularly its decision to deliberately drop messages, which he argues undermines trust in the Fediverse communication network. He reflects on the differing perspectives that emerged from his post, noting a divide between two groups: those who view ActivityPub as a communication protocol focused on message integrity (often older users who prefer traditional communication methods) and those, like Pixelfed creator Dansup, who see it as a content consumption protocol

Rainbow Six Siege is currently experiencing severe issues due to a possible large-scale hack or exploit, despite Ubisoft referring to it as a server incident. Players on various platforms (PC, PS4, PS5, Xbox One, and Xbox Series X|S) are facing service outages, including problems with authentication, in-game store access, and matchmaking. Reports indicate that some accounts are receiving an abnormal influx of in-game currency, rare items, and random bans. The community is advising players to stay offline as

The article recounts the author's experience maintaining a large C++ codebase for an online payment system processing billions of euros annually. Despite acknowledging limited expertise in C++, the author reflects on a significant bug report involving an HTTP endpoint that should return either a success or error status, but ended up showing both fields as true—a scenario that shouldn't be possible due to the code's design. The author dives into the code, which is structured in a single function with clearly defined setting points for each response field. The

The eertree, or palindrome tree, is a data structure created in 2015 by Mikhail Rubinchik and Arseny M. Shur for efficiently searching palindromes within a string. Its name is a palindrome derived from "tree." The structure simplifies the process of understanding and constructing palindromes step by step. Palindromes are classified into three types: single characters, pairs of identical characters (like "aa"), and pairs of identical characters surrounding another palindrome. Nodes in

In a post dated December 26, 2025, Shubham Raizada shares insights on database transaction isolation levels and their relevance in application development. He emphasizes the importance of understanding how concurrent transactions interact to build effective and reliable applications. Raizada defines key concepts: - **Transaction**: A sequence of database operations (such as reads and writes) treated as a single unit of work, where either all operations succeed or none do. - **ACID**: A set of properties

In the second episode of the "Behind The Screen" series, the focus is on web crawlers, essential software that underpins search engines by systematically browsing the internet to gather and index content. The episode outlines the fundamental workings of web crawlers without tying the discussion to specific implementations from companies like Google or Yahoo. The key functions of a web crawler include verifying links, downloading webpage HTML, parsing that HTML for meaningful information, and storing the collected data in a database. The process is managed by

The next goal is to create a fully thread-safe hash map, shifting focus from single-threaded performance to efficient and correct behavior under concurrent access. Real-world applications often involve multiple threads, making it essential to study existing thread-safe hash map implementations that prioritize simplicity, scalability, memory usage, and read/write performance. The simplest method for achieving thread safety is using a single global lock, ensuring that all operations—mutating or not—acquire the same lock to access the hash map's internal state.
