Gleam: A First Impression – Friendly Community Meets Efficient Development

The author learned and used the Gleam programming language to complete a project before going on paternity leave. He was drawn to Gleam's friendly community, concise design, robust type system, and its compilation support for both Erlang and JavaScript. While encountering minor issues, such as redundant type name typing, he was overall pleased with Gleam and plans to continue learning and using it. He hopes Gleam will one day support WebAssembly/WASI and a Python backend.

Unencrypted Radio Signals Expose Central European Power Grid to Catastrophic Attack

Researchers have discovered that renewable energy facilities across Central Europe use unencrypted radio signals to control power distribution, leaving the entire grid vulnerable to a potential catastrophic attack. By replaying or forging signals, attackers could manipulate numerous power facilities, potentially causing widespread blackouts. While the feasibility of such an attack is debated, the vulnerability highlights the urgent need to upgrade existing systems and improve security.

The Myth of the IO-Bound Rails App

2025-01-25

It's a common belief that Rails apps are inherently IO-bound, with the database being the primary performance bottleneck, making Ruby performance less critical. This post challenges that notion. While the database is indeed a scaling bottleneck, the author argues that this doesn't mean the application spends most of its time waiting for I/O. Analysis of YJIT performance improvements and common performance issues (like missing database indexes) suggests many Rails apps are actually CPU-bound. The post highlights confusion between CPU starvation and I/O wait, and emphasizes that choosing the right execution model (asynchronous, threaded, or process-based) depends on the app's I/O/CPU ratio. The author calls for attention to Ruby performance and points out opportunities for optimization within Rails itself.

OpenAI's o1 Model Aces Codenames

OpenAI's o1 model played Codenames against itself, and the results were surprisingly impressive. Over 20 games, o1 consistently demonstrated strong reasoning and a vast knowledge base, both as clue-giver and guesser. Researchers noted o1's superior general knowledge compared to humans, cleverly connecting seemingly unrelated words. Examples included using "007" as a clue, and linking "mail," "lawyer," "line," and "log" with the single word "paper." This showcases the potential of large language models in strategic games, hinting at future applications in diverse game environments.

Do Cookie-Free Analytics Really Need Cookie Banners?

2025-01-25

This article investigates whether so-called "privacy-aware analytics" tools, claiming to perform website analytics without cookies, truly avoid the need for cookie banners. Delving into EU privacy regulations, particularly the ePrivacy Directive, the author finds that even 'cookie-free' analytics might require consent due to accessing information on user devices (like the User-Agent), thus necessitating cookie banners. The author concludes that current technology struggles to completely circumvent EU data access requirements.

The Secret Experiment: Identical Triplets and the Nature vs. Nurture Debate

In 1980, three identical triplets, separated at birth and adopted into different families, unexpectedly reunited. Their story, however, wasn't a heartwarming tale of chance encounters. It revealed a sinister secret: they were unwitting participants in a clandestine psychological experiment designed to unravel the nature versus nurture debate. Researchers, seeking to understand the impact of genetics and environment on behavior, secretly observed the triplets' lives for years. The experiment, however, caused significant emotional distress, with one triplet tragically taking his own life. The ethical implications of this secret study sparked outrage and continue to raise serious questions about the boundaries of scientific research.

Deconstructing Fenwick Trees with Functional Programming

This paper delves into the implementation of Fenwick trees (also known as binary indexed trees). Starting with the more readily understandable segment tree, the author uses functional programming and equational reasoning to derive the implementation of Fenwick trees, revealing the logic behind their seemingly mysterious bitwise operations. By cleverly using a Haskell EDSL to operate on infinite two's complement binary numbers, the paper ultimately explains the secret of Fenwick trees' efficient implementation and proves the logarithmic time complexity of its update and range query operations.
