Generic Programming in C: A Comparison of Four Approaches

Generic Programming in C: A Comparison of Four Approaches

C's lack of support for generic types (parametric polymorphism) is a common frustration. This article explores four methods for emulating generics in C: template macros, template headers, type erasure, and inlining macros. Template macros are simple but suffer from readability and error-proneness; template headers improve readability but still have naming challenges; type erasure sacrifices type safety but is useful for FFI or dynamic linking; inlining macros are user-friendly but lead to code bloat. Ultimately, the author suggests choosing between template headers (easier to develop) and inlining macros (easier to use) based on project needs.

Penn Station Expansion Unnecessary: NYC Ready for Through-Running

Penn Station Expansion Unnecessary: NYC Ready for Through-Running

A new report by the Effective Transit Alliance New York (ETA) refutes Amtrak's claim that a $16.7 billion Penn Station expansion is needed to handle increased ridership from the Gateway Program. ETA argues that the existing Penn Station can accommodate increased ridership through operational changes, eliminating the need for massive expansion. The report analyzes international examples and uses modeling to demonstrate that through-running allows Penn Station to handle 48 trans-Hudson trains per hour, doubling its current peak capacity. ETA urges Amtrak, the MTA, and NJ Transit to abandon the costly expansion plan and instead adopt a more cost-effective operational model.

The Art of Global Variables in C++

2025-02-10

This article explores effective techniques for using global variables in C++. The author argues that global variables aren't inherently bad; the key lies in their proper application. The article presents advantages and disadvantages, outlining four rules: 1. Make it hard to misuse; 2. Restore original values after changing observable states; 3. Don't return references or pointers to internal state; 4. Don't make it hard to test. Through code examples, the author demonstrates correct usage and potential pitfalls, recommending thread-local variables for multi-threading.

Insane Compression: Shrinking 10GB of RATP Transit Data to 530KB with Rust

2025-03-03

This weekend project started by browsing the open-data repository of Paris’ public transport network. The author noticed a section on data reuse, featuring external projects using this open data, particularly the RATP status website which visualizes historical disruptions. The GitHub repository contains JSON files queried every 2 minutes for almost a year, totaling over 10GB. The author wondered if this could be compressed better. This post details how they used Rust's interning design pattern to achieve a 2000x compression! Techniques explored include optimizing the interner structure, tuning the data schema, and leveraging interning in serialization. The result? A staggering reduction from 1.1GB of JSON files to a mere 530KB.

Interstellar Navigation: New Horizons Uses Stellar Parallax

NASA's New Horizons spacecraft, hurtling out of our solar system, offers a unique perspective on the Milky Way. The stars' positions appear significantly different from Earth's view. Scientists have leveraged this parallax effect to achieve the first-ever interstellar navigation using stellar positions. By comparing New Horizons' images of Proxima Centauri and Wolf 359 with data from the Gaia space telescope, researchers calculated the probe's galactic location. While less precise than the Deep Space Network, this method offers advantages at greater distances from Earth, enabling autonomous operation without relying on radio signals from our solar system. Future improvements could significantly enhance accuracy, paving the way for future interstellar missions.

Zero-Sum Games: It's All About Information Warfare

Zero-Sum Games: It's All About Information Warfare

In zero-sum games like poker and quant trading, information asymmetry is key. The game-theoretic optimal (GTO) strategy isn't always best, as it assumes all opponents play rationally. Success hinges on identifying exploitable patterns in opponent behavior while concealing your own strategy. High-frequency trading firms might profit from predictable patterns in competitor algorithms, while those algorithms defend by adding randomness to their trades. This mirrors poker's table image; players can mislead opponents by creating a false pattern of behavior, ultimately profiting. Zero-sum games are fundamentally information warfare, not just a pure strategy contest.

Homomorphic Encryption and Local-First Software: A Trade-off?

This article explores the challenges of using homomorphic encryption to protect private data in local-first software. While homomorphic encryption allows computation without decryption, it introduces significant performance and storage overheads. The author demonstrates the practical limitations of homomorphic encryption on CRDTs by building a homomorphically encrypted 'last-write-wins' register CRDT. The article highlights how homomorphic encryption requires operations under worst-case input assumptions, drastically increasing space and time complexity. Ultimately, the author concludes that securing local-first apps without severely degrading usability remains an open problem.
