C++26: A Giant Leap for Compile-Time Standard Library Features

2025-05-01

C++26 is set to revolutionize compile-time programming with a massive boost to constexpr support in the standard library. Several proposals (P2562R1, P1383R2, P3074R7, P3372R2, P3508R0, P3369R0) bring stable sorting algorithms, and functions, improved union rules, nearly all containers and adaptors, and specialized memory algorithms into the constexpr fold. This significantly enhances compile-time capabilities, allowing, for example, compile-time sorting of constexpr containers. While std::hive and std::hash remain excluded due to limitations, C++26 promises a dramatic expansion of compile-time programming possibilities.

US Homebuilders D.R. Horton and Lennar Accused of Widespread Construction Defects

America's two largest homebuilders, D.R. Horton and Lennar, are facing accusations of widespread construction defects in their new homes, including substandard materials and blatant building code violations, rendering homes unsafe and uninhabitable. Homeowners describe a frustrating warranty process riddled with delays and denials, often leading to expensive repairs out-of-pocket. The investigation reveals a corporate playbook designed to shift costs to buyers through high-pressure sales tactics, one-sided contracts, and legal loopholes to avoid liability. While some homeowners pursue legal action, many find themselves trapped in a system that heavily favors the builders.

Microsoft's Muse AI: Savior or Grave-Digger for Gaming?

Microsoft unveiled Muse, an AI model aimed at assisting game development and even optimizing classic titles for modern hardware. However, the technology has sparked a strong backlash from game developers. They worry that AI tools like Muse will reduce development costs, leading to layoffs and ultimately devaluing the creative contributions of game developers and artists, potentially harming the artistry and creativity of the gaming industry. This highlights the dilemma of AI in gaming: the tension between technological advancement and artistic creation, alongside job security, is increasingly prominent.

How I Use LLMs to Supercharge My Engineering Workflow

2025-02-04

A senior software engineer shares his practical applications of large language models (LLMs) in his daily workflow. He leverages LLMs for code completion, writing throwaway code, learning new domains, last-resort debugging, and proofreading documents. He stresses LLMs are not a replacement for core logic or formal writing but a powerful aid, particularly effective for tackling unfamiliar codebases or learning new technologies. The key is using them strategically, not expecting miracles.

Overusing useCallback and useMemo in React

Overusing useCallback and useMemo in React

This article discusses the overuse of `useCallback` and `useMemo` in React development. The author argues that in many cases, these hooks are used to achieve referential stability, but this is not always necessary and can even lead to performance overhead and code complexity. The article presents several scenarios, such as when components aren't memoized and when props are used as dependencies in effects, where using `useCallback` and `useMemo` provides no performance benefit and adds unnecessary complexity. The author suggests avoiding overuse of these hooks unless there's a clear performance bottleneck and recommends using refs or the upcoming `useEffectEvent` to handle referential stability issues.

The Expression Problem: Elegant Solutions in OOP and FP

2025-09-07

This article delves into the "expression problem" in software design: how to add new data types and operations without modifying existing code. The author uses C++ and Haskell examples to illustrate the limitations of object-oriented and functional programming in solving this problem. The article then explores elegant solutions using the visitor pattern and Clojure's multimethods and protocols. Clojure's approach cleverly leverages the power of open methods, separating method definitions from type definitions, enabling flexible extension without modifying existing code.

AI: The Stone Soup Analogy for LLMs

AI: The Stone Soup Analogy for LLMs

This article uses the parable of 'Stone Soup' to cleverly illustrate the workings of Large Language Models (LLMs). In the story, travelers use a few stones and ingredients provided by villagers to cook a delicious soup. This is similar to how LLMs utilize a small number of algorithms and vast resources from the internet, human feedback, etc., to construct a seemingly 'intelligent' system. The author points out that LLMs are not independent intelligent agents, but rather cultural technologies like internet search engines. Their 'intelligence' stems from the contributions of collective human intelligence, not the magic of the algorithms themselves.

The Demise of the Demo Scene: A Graceful Exit

2025-09-07

The demo scene, recently recognized as a UNESCO Living Cultural Heritage in Sweden, is slowly fading away. This isn't due to a lack of appeal, but rather its unique cultural attributes resisting commodification and replication. Born in the early days of affordable home computers in the 80s and 90s, it thrived on limited resources and communication, fostering a community of passionate programmers and creative individuals. The internet and powerful modern computers have since opened up new creative avenues, offering younger generations a plethora of alternatives. The author argues that the scene's decline is natural, and its essence lies not in perpetuation, but in the joy of creation and preserving its unique charm.

Enterprise Software's Next Frontier: From Records to Autonomous Agents

2025-02-26

Enterprise software is undergoing a revolutionary shift: static data records are evolving into autonomous agents. The article explores three eras of enterprise software: the database era, the cloud era, and the upcoming autonomous agent era. In this third era, leveraging actor models, durable execution, state machines, and LLMs, business objects like invoices gain the ability to autonomously handle processes such as automatic approval, information gathering, policy interpretation, and cross-system coordination. This isn't simply AI replacing humans; it's giving life to data objects themselves, reshaping business processes, enabling more granular operations, and providing more powerful analytical capabilities. Companies are already experimenting with this model, such as CoPlane, Koala, and Hightouch, transforming static data into goal-oriented entities for more efficient workflows.

Infinite Memory: A Theoretical Proof Using Spaced Repetition

2025-02-02

This paper proves that using spaced repetition, an infinitely-lived but forgetful person can recall an infinite number of facts. By establishing a power-law relationship between forgetting and the number of reviews, and considering a finite daily study time, the author derives a model showing that with careful curation of review schedules, knowledge can accumulate indefinitely, ultimately leading to infinite memory. While the daily review load is finite, the cumulative knowledge grows without bound over time.

The 14KB Rule: Why Website Size Matters More Than You Think

2025-07-19

Why is a 14kB webpage significantly faster than a 15kB one? The answer lies in TCP slow start, an algorithm that governs how servers initially send data. This article explains how TCP ensures reliable data transmission and how slow start optimizes bandwidth usage. High-latency networks, like satellite internet, dramatically illustrate the impact: each round trip adds significant delay. The article advocates for minimizing website size to under 14kB or, at the very least, ensuring critical content is within the first 14kB for optimal user experience. While HTTP/2 and HTTP/3 are mentioned, they don't negate the importance of this principle.

This article delves into the advantages and disadvantages of the `eval` function in dynamic languages, particularly its use in Racket. Using vivid analogies, the author compares `eval` to relaying instructions to another person, highlighting how its use increases program complexity and reduces understandability due to language translation and environmental dependencies. While acknowledging that `eval` is sometimes necessary, such as when interacting with external systems, the author emphasizes the need for cautious use and clear context definition. In Racket, `eval`'s behavior is heavily influenced by the execution environment, demanding careful namespace management. Ultimately, `eval` is a powerful tool, but one that demands careful and considered application.
