Why I Ditched Clojure for Common Lisp

2025-01-12

After seven years with Clojure, a programmer switched to Common Lisp due to frustrations with slow startup times and difficulties creating native executables. Key factors in his decision included the need for fast, standalone executables, Vim compatibility, cross-platform support, robust multithreading, and a vibrant community with a rich ecosystem. Common Lisp ultimately won out due to its mature tooling, powerful CLOS and Conditions system, and fast runtime.

Passive Investing's Rise: Is the Myth of Market Efficiency Broken?

Passive Investing's Rise: Is the Myth of Market Efficiency Broken?

Recent market volatility has sparked questions about market efficiency. A new study suggests the rise of passive investing has led to slower reactions by active managers to price discrepancies, amplifying the impact of individual trades. The growing dominance of index funds has decreased market sensitivity to price changes, potentially leading to increased volatility, reduced capital allocation efficiency, and even market failure. While the study's conclusions remain debated, it raises concerns about the potential risks of passive investing, particularly its impact on large-cap stocks.

Automattic Hit with Class-Action Lawsuit: A WordPress Power Play?

A class-action lawsuit has been filed against Automattic and its CEO, Matt Mullenweg, by cybersecurity expert Ryan Keller on behalf of thousands of WP Engine customers. The suit alleges Automattic abused its control over WordPress.org, cutting off WP Engine's access to crucial services, causing disruptions, security risks, and financial losses. While Automattic claims its actions were to protect WordPress's long-term interests, Keller argues it was a calculated move to cripple a competitor, characterizing it as an abuse of the open-source internet architecture. The case highlights a trademark dispute and questions the governance of WordPress, raising concerns about the power wielded by a single entity over a significant portion of the internet. The legal battle promises to be a significant development in the ongoing discussion about open source sustainability and the potential for abuse of dominant positions in the technology sector.

The Curious Case of the Public Domain Jaws Poster

The Curious Case of the Public Domain Jaws Poster

Celebrating the 50th anniversary of Jaws, a surprising fact emerges: due to a quirk of copyright law, the iconic shark painting from the movie poster is in the public domain. Initially rejected for resembling a "vagina with teeth," the artwork underwent revisions before becoming a classic. However, the lack of a copyright notice upon its 1975 publication inadvertently forfeited the image to the public domain, leaving artist Roger Kastel to unsuccessfully fight for copyright recognition years later and missing out on millions in royalties. The original painting's whereabouts remain a mystery, adding another layer to this fascinating tale of copyright and public domain, sparking discussion on artist rights and the commons.

Proving Memoization Correctness in Lean: A Case Study

2025-06-20

Proving Memoization Correctness in Lean: A Case Study

This blog post demonstrates how to solve a dynamic programming problem using memoization in the Lean theorem prover and formally verify its correctness. The author tackles the Bytelandian Gold Coins problem, initially presenting a memoized solution using a HashMap. The difficulty of directly proving its correctness is highlighted due to challenges in reasoning about data structure invariants. The solution leverages subtypes and dependent pairs to create a `PropMap`, a memoization table that stores not only computed values but also proofs of their correctness. The algorithm's correctness is then proven incrementally within the recursive implementation itself, culminating in a trivial top-level proof. This approach elegantly intertwines code and proof, showcasing a powerful technique for formally verifying dynamic programming algorithms.

RISC OS 3.11 GUI: A Retrospectively Advanced Desktop

2025-05-18

This article delves into the unique graphical user interface (GUI) of RISC OS 3.11, released in 1992 by Acorn Computers. Unlike contemporaries like Apple's System 7, RISC OS 3.11 featured a distinct desktop layout with a Pinboard and Icon Bar, innovative three-button mouse interactions, and a menu system seamlessly integrating dialog boxes. Its unconventional approach to window management, including focus and stacking order, along with its drag-and-drop file handling and custom file type support, stands out. The system's intelligent use of mouse buttons reduced keyboard modifier reliance. RISC OS 3.11's GUI remains a fascinating example of unconventional design that offers valuable lessons even today.

JVM Optimization: A VarInt Tale of Unexpected Results

2025-07-25

While optimizing Java code in a massive distributed data processing platform, the author identified VarInt encoding as a potential optimization target. He wrote a highly optimized VarInt encoder using SIMD instructions, achieving a 4x speedup in benchmarks. However, surprisingly, the optimization yielded no improvement in production. The culprit? The benchmark used random numbers, while real-world numbers tend to be much smaller, rendering the algorithm's worst-case performance irrelevant in practice. The change was ultimately reverted, but the experience served as valuable proof-of-concept for developing and productionizing custom JIT optimizations.

Let Users Help Solve Their Own Transit Problems: Beyond Algorithmic Route Planning

2025-01-16

The author criticizes current map apps for relying solely on algorithms to plan public transit routes, neglecting user needs and expertise. He proposes allowing users to customize route options, such as specifying particular bus route combinations, and including these in route planning comparisons. This mirrors the "report spam" and "not spam" functions of email filters, improving algorithms through user feedback. Despite privacy concerns, user participation could enhance route accuracy and user satisfaction, ultimately improving algorithms. The ability for users to add their own route combinations, even without sharing data, would be a significant improvement.
