System Oscillation: From Thermostats to Software Documentation

This article explores common system oscillations, using thermostats and rabbit-hawk populations as examples to illustrate how delayed feedback leads to cyclical fluctuations. The author applies this model to the problem of software documentation, pointing out that excessive documentation becomes outdated over time, diminishing its value. In agile development, the author argues that good code, tests, and team communication can replace redundant documentation, while the advent of generative AI further addresses information retrieval, reducing reliance on outdated documentation.

Keygen's #NoCalls Approach to Enterprise Sales: A Case Study

Keygen founder Zeke Gabrielse shares how his company successfully scaled into the enterprise market by completely eliminating sales calls and embracing asynchronous communication via email. He argues that enterprise clients often resort to calls due to a lack of understanding regarding the product, its usage, pricing, and company trustworthiness. Keygen tackled these issues through clear product messaging, a robust self-serve onboarding experience, transparent pricing, and a focus on publicly available security documentation. This resulted in securing enterprise clients without relying on sales calls. This article offers an alternative sales strategy for founders who dislike traditional sales calls.

Visual Proof: a² – b² = (a + b)(a – b)

Futility Closet's blog post presents a visual proof of the mathematical formula a² – b² = (a + b)(a – b), quoting Sophie Germain's insightful words: “It has been said that algebra is but written geometry and geometry is but diagrammatic algebra.” The post uses an easily understood diagram to demonstrate the formula, highlighting the elegance of mathematics and the strong relationship between algebra and geometry.

Can LLMs Create a Realistic Sheep Herding Game?

A developer challenged large language models (LLMs) to create a sheep herding game called "Shepherd's Dog," focusing on realistic flocking behavior. The detailed prompt included specifications for sheep movement, reactions to the dog and obstacles, and gameplay mechanics. The LLMs were tasked with building the entire game within a single index.html file using HTML, CSS, and JavaScript, featuring at least 10 levels, a timer, scoring system, and saved game progress. The experiment showcases the potential of LLMs in game development.

Alibaba Chairman Warns of AI Data Center Bubble

Alibaba Chairman Warns of AI Data Center Bubble

Alibaba Group Holding Ltd. Chairman Joe Tsai warned of a potential bubble in data center construction, arguing that the current pace of buildout may outstrip demand for AI services. Major tech firms and investment funds are aggressively building server farms globally, often without securing clear customers. Tsai expressed concern about projects raising funds without firm uptake agreements. While Alibaba itself plans to invest over $52 billion in AI over the next three years, Tsai highlighted the massive spending by US tech giants (Microsoft, Amazon, Google, Meta) on AI infrastructure, suggesting it might exceed current and projected demand. He pointed to the low-cost, open-source AI model from DeepSeek as an example of the current lack of widespread practical AI applications. Alibaba's response involves leveraging the success of its Qwen-based AI platform and an internal 'reboot' focusing on talent acquisition.

Achieving Polymorphism with Dynamic Dispatch in Zig

2025-07-19

Zig, unlike many languages, lacks built-in interfaces. However, this doesn't preclude polymorphism. This article details a method for achieving dynamic dispatch polymorphism in Zig using vtable interfaces. This approach cleanly separates interfaces from implementations, requiring no changes to implementation types while enabling dynamic dispatch. It leverages function pointers to construct a vtable and uses an `implBy` function to connect implementations to the interface, effectively mimicking the functionality of interfaces in object-oriented languages. This allows storing different implementations in arrays or maps. While some boilerplate code is involved, the advantages are a clean, flexible, and reusable approach with minimal impact on implementation types.

North Korea's Crypto Laundering Scheme: A Billions-Dollar Headache

North Korea's hacking spree has netted billions in cryptocurrency, but converting this loot into fiat currency presents a massive challenge. Unable to use major exchanges due to KYC regulations, they rely on a global network of over-the-counter brokers, particularly in under-regulated regions like China. The sheer volume of funds, however, creates a significant bottleneck, leaving vast sums of crypto trapped in wallets – a modern-day equivalent of Escobar's cash storage problem. While employing mixers and other tools to obfuscate transactions, North Korea faces persistent pressure from nations like the US, who employ various methods to track and seize these illicit funds. This includes using provisions in the USA PATRIOT Act to subpoena Chinese banks, a strategy requiring significant political capital.

SymbolicAI: A Neuro-Symbolic Framework for LLMs

SymbolicAI is a neuro-symbolic framework blending classic Python programming with the differentiable programmability of LLMs. Its modular design allows easy extension and customization, enabling users to write their own engines, host them locally, or interface with tools like web search and image generation. Core concepts are Symbol objects (syntactic and semantic) and contracts (ensuring code correctness via decorators). SymbolicAI supports numerous primitive operations and integrates with neuro-symbolic engines like OpenAI and Anthropic via APIs, along with tools such as Wolfram Alpha and search engines. A priority-based configuration system simplifies management.

Enum of Arrays: A Novel Data Structure for Efficient Data Processing

This article introduces a data structure called "Enum of Arrays" (EoA), similar to the popular "Struct of Arrays" (SoA), but with enums at its core. EoA packs multiple enum values into an array, using a single tag to identify the array's type. This reduces memory usage and branch prediction overhead, leading to more efficient data processing, particularly beneficial for SIMD optimization. The article uses the database system TigerBeetle as an example, illustrating how EoA enables efficient batch processing by effectively separating the control plane and data plane, resulting in significantly improved performance.

JRuby: Elegant Java Integration Solves External Library Headaches

2025-05-01

At RubyKaigi, the author encountered difficulties using external libraries in Ruby: C libraries require writing C extensions or FFI bindings, while other languages pose even greater challenges. Examples like Charty (wrapping matplotlib) and QuickChart (implemented in JavaScript) highlighted the clumsiness of existing solutions. The author proposes a more elegant approach: leveraging JRuby's Java integration. Using JFreeChart as an example, the article demonstrates how to create charts effortlessly without writing Java, C, Python, or JavaScript code. It details JRuby's Java integration layer, including managing dependencies with `jar-dependencies`, calling Java classes, and creating simple bar and pie charts. The author concludes with an encouragement to experiment with JRuby and support its continued development.

AWS S3's latest SDK update defaults to strong integrity checksums, a positive security step, but breaks compatibility with many S3-compatible services like Minio, Vast, and Dell EC. Projects such as Trino and Apache Iceberg are experiencing compatibility issues as a result, with Iceberg even submitting a PR to disable the feature. This highlights the risks of relying directly on S3 SDKs and shines a spotlight on OpenDAL. OpenDAL, by directly communicating with APIs, avoids SDK-related compatibility problems, offering users a more stable and reliable data access method.
