UbuWeb Hosts a Massive 476-Track History of Electronic Music

UbuWeb, a repository of 20th-century avant-garde works, now features a colossal compilation: a 476-song History of Electronic/Electroacoustic Music, originally a 62-CD set. While lauded for its scope (spanning 1937-2001), the collection has drawn criticism for its Western-centric bias and underrepresentation of female composers. Despite these flaws, it remains a significant resource for exploring the history of experimental sound, prompting further exploration of a more inclusive and comprehensive history of electronic music.

Dedekind Cuts: A Revolutionary Approach to Defining Real Numbers

Dedekind Cuts: A Revolutionary Approach to Defining Real Numbers

This article delves into Richard Dedekind's 1858 proposal of Dedekind cuts, a revolutionary approach that provided a firm foundation for the real number system. Dedekind cleverly used partitions of rational numbers to define real numbers, elegantly solving the problem of 'gaps' in the real number system caused by irrational numbers. The article compares Dedekind cuts with other methods of defining real numbers, such as infinite decimals, and analyzes the advantages and disadvantages of Dedekind cuts, as well as their impact and significance in mathematical history. Dedekind cuts not only resolved the definition of real numbers but also pioneered a new way of thinking in mathematics—the structuralist approach—emphasizing the relationships between mathematical objects rather than the inherent nature of the objects themselves.

Rust Error Handling: A Hybrid Approach with Snafu

Error handling in Rust is a hotly debated topic. `anyhow` offers a generic error type for easy debugging, while `thiserror` provides precise enum types for better API design. This article details Iroh's hybrid approach using Snafu, which combines the precision of `thiserror` with the ease of use of `anyhow`, while overcoming Rust's backtrace limitations. It cleverly preserves detailed context and backtraces in error chains. The `n0-snafu` crate further simplifies Snafu usage, particularly in tests. Iroh's choice of Snafu balances precision and usability for efficient error handling.

The Mathematical Magic Behind Undergraduate Divisibility Problems

The Mathematical Magic Behind Undergraduate Divisibility Problems

This blog post explores the origin of common problems in undergraduate mathematics courses, such as proving that a polynomial is always a multiple of a certain integer. The author points out that these problems stem from combinatorial counting, specifically Pólya-Redfield counting. This method uses the orbit-counting formula under group action to connect the value of a polynomial to the counting of a certain combinatorial structure, ensuring the polynomial is always a multiple of a specific integer. The article uses two examples, bracelet counting and tic-tac-toe board counting, to explain how Pólya-Redfield counting is used to construct these problems. It also proposes a conjecture about whether all such polynomials originate from Pólya-Redfield counting.

Malicious nx Packages on npm: Credential Theft and System Shutdown

Multiple versions of the npm package 'nx' (including 21.5.0, 20.9.0, etc.) were maliciously compromised. An attacker used a stolen npm token to publish packages containing code that scans the user's file system, collects credentials (GitHub, system passwords, etc.), and uploads this information to a GitHub repository under the user's account. The malicious code also modifies the user's `.zshrc` and `.bashrc` files to execute `sudo shutdown -h 0` upon terminal launch, potentially shutting down the system. Affected users should immediately update their 'nx' package to the latest version and check their GitHub for compromised repositories. Nx has removed the malicious packages and implemented enhanced security measures, including mandatory 2FA and the new Trusted Publisher mechanism for all npm packages.
