C++ Modules: A Broken Promise?

2025-09-01

This article takes a pessimistic view on the progress of C++ modules. The author argues that if C++ modules cannot demonstrate a 5x (preferably 10x) compilation speedup across multiple existing open-source codebases, they should be abandoned. The article highlights the challenging development journey, citing the tight integration required between compilers and build systems as a major hurdle. The author emphasizes that the focus should be on improving compilation speed rather than addressing relatively rare issues like macro leakage. He recounts the standardization process, pointing out underestimation of implementation difficulties. Finally, the author suggests an alternative approach – `import std` – while acknowledging its limited potential for improvement.

patolette: A PCA-Based Color Quantization and Dithering Library

patolette is a C/Python library for color quantization and dithering, implementing a weighted variant of Xiaolin Wu's PCA-based quantizer. Key features include support for CIEL*u*v* and ICtCp color spaces, optional saliency map weighting for visually prominent areas, and optional KMeans refinement. While still under development and lacking a PyPI package, it's usable now. Manual installation is required, with AVX instruction set support for performance boosts. The library doesn't handle image decoding/encoding; users must handle that themselves.

Disk I/O Beats Memory Caching? A Surprising Benchmark

2025-09-05

Conventional wisdom dictates that memory access is far faster than disk I/O, making memory caching essential. This post challenges that assumption with a clever benchmark: counting the number of tens in a large dataset. Using an older server and optimizing code (loop unrolling and vectorization), along with a custom io_uring engine, the author demonstrates that direct disk reads can outperform memory caching under specific conditions. The key isn't that the disk is faster than memory, but rather that traditional memory access methods (mmap) introduce significant latency. The custom io_uring engine leverages the disk's high bandwidth and pipelining to mask latency. The article emphasizes adapting algorithms and data access to hardware characteristics for maximum performance in modern architectures, and looks ahead to future hardware trends.

LLMs: Accelerating Incompetence in Software Engineering

LLMs: Accelerating Incompetence in Software Engineering

This essay argues that over-reliance on Large Language Models (LLMs) in software engineering can accelerate incompetence. An experienced software engineer details how LLMs, while offering speed in code generation, introduce significant risks: incorrect outputs, inability to understand context, increased technical debt, and the suppression of critical thinking and creativity. Drawing on the insights of Peter Naur and Fred Brooks, the author emphasizes that programming is about building program theory and managing program entropy, tasks beyond current LLMs' capabilities. The essay concludes that while LLMs are useful tools, they cannot replace human ingenuity and deep thinking, and over-reliance can lead to increased costs and project failures.

Breaking WebAssembly Runtime Limitations: Asyncifying ZeroPerl

Frustrated by the lack of exnref support in most WebAssembly runtimes, rendering ZeroPerl unusable, the author decided to fix the problem instead of complaining. By leveraging Binaryen's Asyncify feature, a replacement for setjmp was implemented from scratch, bypassing libsetjmp's compatibility issues. After removing the official library, writing assembly code, and optimizing with wasm-opt, ZeroPerl now runs successfully in Wasmer, Wasmtime, and other WebAssembly runtimes. This breakthrough delivers a fully sandboxed and self-contained Perl WebAssembly module.

LLMs Crack a Byzantine Music Notation Cipher

2025-04-04

Researchers discovered that large language models like Claude and GPT-4 can decode a peculiar cipher based on the Byzantine music notation Unicode block. This cipher resembles a Caesar cipher, but with an offset of 118784. The models can decode this cipher directly without chain-of-thought, achieving even higher success rates than with regular Caesar ciphers. Researchers hypothesize this is due to a linear relationship between addition in a specific Unicode range and addition in token space, allowing the models to learn a shift cipher based on this relationship. This phenomenon suggests the existence of yet-ununderstood mechanisms within LLMs.

The Enigmatic Leatherman: A Historical Mystery

In the latter half of the 19th century, a mysterious vagrant known only as the "Leatherman" roamed the northeastern United States. Clad in a handmade leather suit, he followed a 365-mile circuit, returning to the same towns every 34 days. His identity remains shrouded in mystery; while fluent in French, his English was broken, and a French prayer book was found upon his death. His means of sustenance are unknown, yet he was accepted by local communities, with some towns even exempting him from vagrancy laws. He died of mouth cancer in 1889, leaving behind a compelling enigma that continues to intrigue historians and researchers.

Concussions May Reactivate Brain Virus, Increasing Dementia Risk: Organoid Study

A new study using brain organoids—3D clumps of neuronal tissue derived from human stem cells—has modeled the effects of concussions on the brain. Researchers found that repeated head impacts may contribute to Alzheimer's and other dementias by reactivating latent herpes simplex virus type 1 (HSV-1). In organoids infected with HSV-1, repeated jolts reactivated the virus, leading to increased beta-amyloid protein and neuroinflammation, hallmarks of Alzheimer's. This research provides new insights into the link between traumatic brain injury and dementia, potentially opening avenues for preventative and therapeutic strategies.

Transparency Paradox: How Openness Can Backfire and Reduce Public Trust in Science

A study reveals the 'transparency paradox': while transparency in science fosters trust, revealing bad news (like conflicts of interest or failed experiments) can decrease it. The root cause, argues the researcher, is the public's overly idealized view of science. The solution isn't hiding bad news, but improving science education and communication to present a more realistic picture—science isn't perfect, and scientists make mistakes. This fosters more realistic expectations and ultimately, increased trust.

Small but Mighty: Exploring the Beauty of Concise Programming Languages

2025-06-06

This article explores the trade-off between the size and expressiveness of programming languages. The author argues that smaller languages like assembly are limited in expressiveness, while languages like Forth, Lisp, and Tcl achieve powerful expressiveness with concise syntax. Lua is highlighted as a small and easy-to-learn language due to its tiny core (just 27 pages!). The impact of standard libraries on perceived language size is discussed, with Ramda's extensive functionality used as an example of increased learning curve. Ultimately, the author champions the elegance and joy of small languages, suggesting that simplicity can sometimes trump expressiveness.
