Viral Poetry: Algorithms, Community, and the Death of Aesthetics

This essay explores why certain poems go viral on social media, yet attract fierce criticism. The author analyzes three viral poems, identifying common traits: juxtaposing the mundane and profound, using contemporary poetic forms, signaling a political ingroup, urging a moral or therapeutic takeaway, and exhibiting 'cringe' qualities. These elements fuel generational divides. The author argues that social media algorithms dictate the poems' trajectory, not their artistic merit. In the fast-paced online environment, poetry becomes social currency, losing its aesthetic value and space for deep reflection.

Parisian Kebab Quality vs. Train Station Proximity: A Hilarious Data Analysis

2025-02-24

A self-proclaimed unemployed, autistic Swede on Reddit undertook an "informal study" to test a French Redditors' hypothesis: "The closer to the train station, the worse the kebab." Using OSMnx for map data, the Google Places API for kebab shop information and ratings, and NetworkX for distance calculations, he meticulously cleaned and analyzed the data. The result? Almost no correlation (Pearson correlation coefficient of 0.091), debunking the initial hypothesis. Despite the disappointing outcome, this post is a hilarious account of the process, filled with programmer humor and frustration. It's a fun tech share and a compelling data analysis case study.

Modular Forms: Unveiling Hidden Symmetries and Infinite Possibilities

Mathematicians have discovered that modular forms, a special type of function, possess infinite symmetries stemming from their unique transformation properties on the complex plane. These transformations replicate the fundamental domain to the entire upper half-plane, relating copies through specific rules. While seemingly simple geometric operations, they hold immense power. Hecke's theory revealed that modular forms reside in specific spaces, allowing us to leverage their infinite symmetries to tackle problems like representing integers as sums of four squares. By converting sequences into generating functions, if the function is a modular form, coefficients can be precisely calculated, unlocking infinite possibilities. This provides a powerful tool for solving numerous problems in mathematics and physics.

Neut: A Functional Programming Language with Static Memory Management

2025-02-24

Neut is a functional programming language featuring static memory management, cleverly combining full λ-calculus support, predictable automatic memory management, and the absence of type system annotations. Unlike traditional garbage collection, Neut uses a type-directed approach to resource handling. The compiler ensures each variable is used exactly once by translating types into functions that can discard or copy values. Even when copying is necessary, Neut avoids unnecessary overhead using the T-necessity operator in modal logic, similar to Rust's borrowing. Neut compiles to LLVM IR and binaries, and boasts built-in LSP server, code formatter, and a rapid prototyping experience akin to scripting languages. Its unique module system distinguishes modules using tarball digests and defines module identities with version information.

A Hidden Bug in DOS 3.3 SYS.COM: The NetDrive Disk Image Corruption Mystery

2025-02-24

This article details the author's investigation into a bug in the DOS 3.3 system command `SYS.COM`. This command copies boot loader code to a disk, but when used with NetDrive virtual disk images, it corrupts the image. Through careful analysis, the author discovered that `SYS.COM` fails to check the return code of a Generic IOCTL call used to obtain disk parameters. When this call fails (e.g., the NetDrive driver doesn't support the function), `SYS.COM` erroneously writes garbage data to the disk's boot sector, corrupting the image. This bug only manifests on certain disk image types (e.g., hard disk images) because DOS attempts to retrieve disk geometry information, whereas floppy disk images do not. The author ultimately pinpoints the bug's root cause and explains the conditions under which it occurs.
