The Myth of the IO-Bound Rails App

2025-01-25

It's a common belief that Rails apps are inherently IO-bound, with the database being the primary performance bottleneck, making Ruby performance less critical. This post challenges that notion. While the database is indeed a scaling bottleneck, the author argues that this doesn't mean the application spends most of its time waiting for I/O. Analysis of YJIT performance improvements and common performance issues (like missing database indexes) suggests many Rails apps are actually CPU-bound. The post highlights confusion between CPU starvation and I/O wait, and emphasizes that choosing the right execution model (asynchronous, threaded, or process-based) depends on the app's I/O/CPU ratio. The author calls for attention to Ruby performance and points out opportunities for optimization within Rails itself.

Do Cookie-Free Analytics Really Need Cookie Banners?

2025-01-25

This article investigates whether so-called "privacy-aware analytics" tools, claiming to perform website analytics without cookies, truly avoid the need for cookie banners. Delving into EU privacy regulations, particularly the ePrivacy Directive, the author finds that even 'cookie-free' analytics might require consent due to accessing information on user devices (like the User-Agent), thus necessitating cookie banners. The author concludes that current technology struggles to completely circumvent EU data access requirements.

Deconstructing Fenwick Trees with Functional Programming

2025-01-25

This paper delves into the implementation of Fenwick trees (also known as binary indexed trees). Starting with the more readily understandable segment tree, the author uses functional programming and equational reasoning to derive the implementation of Fenwick trees, revealing the logic behind their seemingly mysterious bitwise operations. By cleverly using a Haskell EDSL to operate on infinite two's complement binary numbers, the paper ultimately explains the secret of Fenwick trees' efficient implementation and proves the logarithmic time complexity of its update and range query operations.

Simplifying a Haskell Backend with GADTs: A Tale of Two Lambda Box Targets

2025-01-24

This blog post details how the author used Generalized Algebraic Datatypes (GADTs) in Haskell to simplify the development of an Agda compiler backend. Facing the challenge of compiling to two different Lambda Box intermediate language targets (typed and untyped), the author leveraged GADTs and dependent types to elegantly avoid code duplication and enforce type safety. The type system prevents the omission of type information for the typed target. This practical example demonstrates the power of GADTs in everyday programming and showcases how dependent types can help prevent errors, resulting in cleaner, more maintainable code.

C++26: Pack Indexing Simplifies Element Extraction

2025-01-24

While C++11 introduced parameter packs, extracting specific elements remained cumbersome. C++26, thanks to proposal P2662R3, introduces pack indexing, allowing direct access to pack elements using the subscript operator, e.g., `T...[0]` for the first element. This leads to cleaner, more readable code and improved compile-time performance. Although negative indexing and slicing aren't yet supported, the feature is already highly usable, significantly improving C++ development.

Near-Perfect Book-Sorting Algorithm Achieved

2025-01-24

A breakthrough in the "library sorting problem" (also known as the "list labeling" problem) has been achieved. The problem focuses on finding the most efficient way to organize books or files in a database to minimize the time needed to insert new items. A team developed a new algorithm that comes tantalizingly close to the theoretical optimum (log n) for average insertion time. This algorithm cleverly combines limited knowledge of past contents with the surprising power of randomness, solving a decades-old challenge. This research has implications not only for librarians but also for database and hard drive organization, promising significant improvements in data storage and retrieval efficiency.
