Ruby 3.4: Faster Connections, Cleaner Backtraces, and More Concise Code

2025-01-01

Ruby 3.4 is here! Chris Sinjakli highlights three key improvements: a default block parameter name `it` for cleaner code; implementation of RFC8305 (Happy Eyeballs Version 2) for significantly improved TCP socket connection handling, especially in dual-stack (IPv4 and IPv6) networks; and clearer exception backtraces for easier debugging. These enhancements boost developer productivity and underscore the Ruby team's commitment to developer experience.

US Net Neutrality Rules Struck Down Again

A US appeals court has dealt another blow to net neutrality, overturning the FCC's latest attempt to reinstate the rules. The 6th Circuit Court of Appeals cited the Supreme Court's Loper Bright decision, arguing the FCC lacked the authority to reclassify internet service providers as common carriers. This decision, based on a Supreme Court ruling limiting agencies' power to interpret laws, effectively kills the FCC's April order. The long-running battle over net neutrality continues, with FCC Chairwoman Rosenworcel calling for Congressional action to codify open internet principles into federal law.

LLM Performance on Advent of Code 2024: A Surprise

This post details an experiment testing several leading Large Language Models (LLMs) on the 2024 Advent of Code challenge. Surprisingly, the LLMs performed worse than expected, even underperforming the author. A simple framework was used, providing the models with the complete problem description and requiring executable Python code. Results showed frequent timeouts and exceptions, suggesting LLMs excel at solving familiar problems but struggle with novel ones. This limitation might stem from reliance on program templates, insufficient computational resources, or suboptimal prompting. The experiment highlights Advent of Code as a potential benchmark for evaluating coding agents.

An Engineer's Journey with Forth: From Fascination to Abandonment

2024-12-28

This blog post recounts an engineer's experience learning and using the Forth programming language. Initially captivated by Forth's brevity and extensibility, the author delved into the source code of pForth, marveling at its compile-time self-modifying capabilities. However, in real-world projects, the author found Forth more suitable for number crunching, struggling with tasks like text processing. While designing a custom hardware embedded system, the author leveraged Forth to design the system's CPU instruction set, but ultimately found C more efficient and abandoned Forth. The author concludes that Forth is ideal for minimalist engineers seeking extreme efficiency, while he himself prefers a more pragmatic approach, opting for more widely used languages.

The Magic of Metalinguistic Programming: Simplifying Code with Interpreters

This article explores the power of metalinguistic programming, specifically using interpreters to simplify complex code. The author uses Lisp expression simplification as an example, showing how building an 80-line Scheme interpreter and 30 rules can accomplish a task that would otherwise require thousands of lines of code. The key is shifting the programming paradigm to data-driven rule matching, avoiding significant code duplication. While not magic, the author argues this metalinguistic abstraction is a powerful tool worthy of further exploration.

The Right to Root: Why You Should Own Your Devices

2025-01-13

This article argues for a "right to root" – the consumer's right to install and modify software on any computing device they own outright, regardless of form factor. The author contends that manufacturers' restrictions, justified by security concerns, are anti-consumer, stifle competition, and lead to shorter device lifespans and limited repair options. Using Apple devices as a prime example (comparing the open nature of MacBooks to the closed nature of iPads), the article discusses potential legal solutions and emphasizes that manufacturers should bear the burden of proving the necessity of hardware locks, except in cases like critical medical devices.
