Literate programming is a concept that integrates code with prose, allowing readers to understand a codebase as a narrative. While intriguing, the practical application of literate programming can be cumbersome, as it requires maintaining both code and accompanying prose, which limits its adoption. Historically, it has found use in data science, particularly with Jupyter notebooks where explanations and results coexist. Emacs Org Mode also supports this through its org-babel package, but its complexity makes it a niche option for larger software

The content discusses methods for performing dynamic instance type checks in virtual machines with single inheritance. It outlines two main strategies for checking if an object of type `t` is also of a more specific type `u`. The first method involves representing the types as a directed acyclic graph (DAG) with pre-order and post-order numbering derived from a depth-first search. When an object of type `t` is created, its pre-order number is stored as a tag, allowing for efficient type checks at

In February 2021, Gab, a social network, suffered a data breach where a hacker stole 70 GB of user data, including posts, messages, and passwords. The breach was caused by a SQL injection vulnerability introduced by Gab's CTO, which allowed the attacker to exploit the system's code. A follow-up attack occurred shortly after, using stolen OAuth2 tokens from the initial breach. This incident highlights the broader security issue of input handling in internet-connected systems. Every input entering a system—from

In this post, the author argues that NestJS, despite its popularity and robust features as a TypeScript backend framework, is not truly type-safe due to its reliance on classes and decorators, which are problematic in TypeScript. The author acknowledges the efforts of NestJS and class-validator maintainers but highlights that the framework's default setup leads to issues with data validation. Specifically, decorators in TypeScript lack typing, which allows for incorrect code to pass without warnings. This fundamental limitation prevents effective type safety within

Researchers from universities and IBM collaborated to create a groundbreaking molecule featuring a half-Möbius electronic topology, which had not been previously theorized. The study, published in Science, involved constructing the molecule atom-by-atom using advanced quantum-centric supercomputing that integrates quantum and classical systems. This achievement reflects the ideas of physicist Richard Feynman about engineering matter on an atomic scale and the necessity of quantum mechanics for simulating nature effectively. Typically, molecules have a "topologically trivial" ring
