To Compile or Not to Compile Database Queries: A Deep Dive

2025-02-12

This article explores the trade-offs of compiling database queries. Traditional query interpreters struggle with the speed of modern NVMe SSDs, leading to significant performance bottlenecks. Compiling queries offers substantial speed improvements, especially for OLAP workloads. However, compilation time and optimization challenges create unpredictable performance cliffs. Vectorized interpreters, conversely, are easier to build, debug, and offer more consistent performance. The article contrasts this with browser JavaScript/Wasm engines, which use a tiered compilation approach (interpreter, baseline compiler, optimizing compiler) to achieve a smooth performance trade-off. The author proposes a similar approach for databases, suggesting a baseline compiler as a key component. Several implementation strategies, including 'copy-and-patch' and Wasm compilation, are explored. Ultimately, the article argues that building a baseline compiler isn't prohibitively difficult and offers perspectives on future directions.

Xcode 16's Local Package Dependency Nightmare: Why I'm Using Two Editors

Developer Christian Tietze encountered significant issues with Xcode 16 while working on a Swift Package. Xcode 16's altered approach to local package referencing broke file operations, test running, and more. To overcome this, he's forced to use both Xcode (for compiling and running the app) and Emacs (for editing and testing the package). The post laments Xcode 16's buggy update, Apple's aggressive software upgrade policy, and recommends developers learn a backup editor.

Versailles: Power and the Absence of Soul in Design

2025-02-19

The construction of Versailles stemmed from Louis XIV's lust for power and envy of his former finance minister's magnificent gardens. The author uses this as a springboard to discuss the lack of soul in modern product design. He argues that, much like Versailles is awe-inspiring yet lifeless, many modern products prioritize superficial aesthetics and functionality, neglecting emotional connection. True design, he contends, should stem from the designer's emotional experiences, drawing inspiration from their own depths, like a gardener cultivating the soil, to create products full of life. The article uses architecture as an example, contrasting the feelings evoked by the Sagrada Família and a telephone exchange building, highlighting the importance of emotion in design.
