Svelte 5 Migration: Performance Gains, Cognitive Overhead

Upgrading a web application to Svelte 5 led to unexpected issues. Svelte 5's performance improvements, driven by "deep reactivity," introduce proxies and implicit component lifecycle state. While seemingly simpler, this adds abstractions, requiring developers to manage complex heuristics. Proxies aren't objects, and components aren't functions. The author details problems with proxies and callbacks, such as `DataCloneError` and props becoming undefined after component unmounting. Svelte 5 sacrifices developer agency, increasing cognitive load, leading the author to abandon it for new projects. The conclusion emphasizes choosing tools that leverage existing knowledge and promote understanding over cleverness.

Tech's Misuse of the Pareto Principle: 80% Effort, 20% Product?

In game development, the concept of a 'vertical slice' emphasizes completeness, while the tech industry's prevalent 'Minimum Viable Product' (MVP) prioritizes rapid iteration. The author argues that overemphasis on the Pareto Principle (80% of results from 20% effort) leads to many tech products remaining rough MVPs, lacking final polish and leaving users dissatisfied. This isn't just seen in apps and software but also impacts AI, like self-driving cars and image generation; these are promising but far from practical. The author calls for a shift in mindset, valuing completeness and user experience over rapid iteration and funding.

Span<T> Beats memcmp: Massive Performance Gains in .NET Byte Array Comparisons

This post benchmarks various byte array comparison methods in .NET, including `memcmp`, looping, `Enumerable.SequenceEqual`, and `Span.SequenceEqual`. Results show `Span.SequenceEqual` offers the best performance in .NET 8 and later, significantly outperforming `memcmp` and traditional looping, even on .NET Framework. For small arrays, looping is fastest, but `Span.SequenceEqual`'s advantage grows dramatically with array size. The author recommends using `IEnumerable.SequenceEqual` in .NET 8+ and `Span.SequenceEqual` in .NET Framework, avoiding `memcmp` and custom implementations.

Rendering the Impossible: Introducing Meschers

2025-09-06

Representing impossible objects – geometric constructions perceivable but not physically realizable – has been a challenge in computer graphics. Existing methods, like cutting or bending, disrupt geometry, hindering downstream processing. This paper introduces Meschers, a novel mesh representation based on discrete exterior calculus. Instead of 3D vertex positions, Meschers store 2D screen-space positions and per-edge depth differences, allowing representation of Escher-like impossibilities. This enables standard geometry processing operations like smoothing, heat diffusion, and geodesic distance queries, as well as inverse rendering, deforming possible shapes into impossible ones. Meschers offer new avenues for understanding human visual perception and expanding computer graphics capabilities.
