Rebuilding the C++ Standard Library from Scratch: The Pystd Project

Tired of the C++ Standard Library's (STL) abysmal compile times and unreadability, a self-employed open-source developer decided to build a replacement from scratch: Pystd. Taking inspiration from the Python standard library, he incrementally implemented file handling, string manipulation, UTF-8 validation, hash maps, vectors, and sorting. The result? A functional application in under 1000 lines of code, comparable to the STL version. Pystd boasts significantly faster compilation and smaller executable sizes. A unique versioning scheme (e.g., pystd2025) ensures perfect ABI stability, easing future upgrades and maintenance.

Librarians: More Dangerous Than You Think

This article playfully celebrates the powerful influence of librarians. Starting with the provocative statement, "Librarians are dangerous," the author explains that this danger isn't in a physical sense, but rather in their positive impact on society. Librarians are portrayed as agents of change, promoting literacy, information literacy education, and community engagement. They are not simply guardians of books but disseminators of knowledge and igniters of minds, playing a crucial role in combating misinformation, fostering equality, and building a better world. The author encourages readers to reassess the value of librarians and pay tribute to their work.

Holes in Topological Spaces: Homotopy and Weak Homotopy Equivalence

2025-06-23
Holes in Topological Spaces: Homotopy and Weak Homotopy Equivalence

This article explores the concept of 'holes' in topological spaces and introduces two equivalence relations: homotopy equivalence and weak homotopy equivalence. Homotopy equivalence allows spaces to be deformed while preserving the number of 'holes,' such as a coffee cup and a torus being homotopy equivalent. Weak homotopy equivalence is more relaxed, requiring only that spaces have the same homotopy groups, even if they differ in local structure. The article delves into the concept of homotopy groups and illustrates how to identify 'holes' in spaces using homotopy groups with the example of a torus. Finally, it mentions Grothendieck's conjecture that the infinity groupoid captures all information about a topological space up to weak homotopy equivalence, which is closely related to weak factorization systems and Quillen model categories.

Building LLMs from Scratch: Vectors, Matrices, and High-Dimensional Spaces

This article, the second in a three-part series, demystifies the workings of Large Language Models (LLMs) for technically inclined readers with limited AI expertise. Building on part 19 of a series based on Sebastian Raschka's book "Build a Large Language Model (from Scratch)", it explains the use of vectors, matrices, and high-dimensional spaces (vocab space and embedding space) within LLMs. The author argues that understanding LLM inference requires only high-school level math, while training requires more advanced mathematics. The article details how vectors represent meaning in high-dimensional spaces and how matrix multiplication projects between these spaces, connecting this to linear layers in neural networks.

Zuckerberg's Testimony: Smoking Gun in Meta Antitrust Case

2025-04-26

The FTC's antitrust trial against Meta is underway, and Mark Zuckerberg's testimony has emerged as a pivotal moment. Prosecutors used Zuckerberg's own internal emails as damning evidence, revealing his admission that the acquisitions of Instagram and WhatsApp were intended to eliminate competition. Emails show Zuckerberg was aware of potential antitrust violations yet proceeded with the acquisitions, subsequently implementing strategies to restrict Instagram's growth and increase ad load. While Meta argues it's not a monopoly, Zuckerberg's testimony strongly supports the prosecution's case of anti-competitive behavior, significantly strengthening their position.

XSLT: A Zero-Config Static Site Generator Built into Your Browser

Tired of complex build systems like Next.js, the author sought a simpler way to build static websites. After exploring various options, they discovered XSLT, a language for transforming XML into HTML. By storing website data as XML and using XSLT for transformation, they created a 'client-side' build system requiring no extra tools. The browser handles the XSLT transformation directly, generating the final HTML—a zero-config solution for static site generation. While not a perfect replacement for all scenarios, it offers developers a powerful alternative.

Chrome 136 Finally Kills 23-Year-Old Browser History Sniffing Vulnerability

A 23-year-old vulnerability allowing websites to sniff users' browsing history through CSS :visited pseudo-class is finally being eradicated in Chrome 136. Previous attempts to mitigate the issue, which involved checking link colors to determine if a page had been visited, proved insufficient. Chrome 136 introduces a novel 'partitioning' mechanism, linking visited history to the link URL, top-level domain, and frame origin, preventing cross-site access to browsing history. This breakthrough represents a significant leap forward in browser privacy and concludes a decades-long arms race between attackers and defenders.
