Quivers: Rethinking a Year of Linear Algebra as Graphs
Nikita Lisitsa introduces quivers—directed multigraphs—and shows how assigning vector spaces to vertices and linear maps to edges turns standard linear algebra into representation theory. Simple quivers recover familiar topics like bases, Gaussian elimination, and Jordan blocks, now seen as decompositions into indecomposable representations. Slightly richer graphs lead to Kronecker canonical form used in control theory, and finally to “wild” quivers whose representations defy full classification. It’s a concise tour from classroom linear algebra to the frontier of algebra.
Smuggling Managed Data into Unity Jobs with GCHandle
Unity’s job system requires job structs to be fully unmanaged, which blocks you from using classes and other managed data directly in jobs. This post shows how to use GCHandle as an “escape hatch” to pass a managed reference into an IJob and retrieve it in Execute—at the cost of losing Burst compilation. The author stresses that GCHandles are not free and can cause GC contention. Use this technique sparingly, ideally only as a temporary bridge toward fully unmanaged data.
🎮 Leveling Up Game Development
Apple Supercharges Game Dev with On‑Device AI and Porting Tools
Apple is rolling out a major AI upgrade for developers, with Core AI enabling full-scale large language models to run directly on Apple devices. Game teams get Managed Background Assets, Game Porting Toolkit 4, fresh Unity plug-ins and an improved Reality Composer Pro 3 to streamline ports and spatial experiences. An expanded Foundation Models framework unifies access to Apple, Anthropic, Google, OpenAI and more through Swift. Xcode 27 adds “agentic” AI coding for planning, generation and automated testing.
5 Painful Steamworks Gotchas Every Indie Should Fix Before Launch
A veteran Steamworks user breaks down five common mistakes that quietly kill indie visibility and sales. Learn how to actually get the big green demo button for Next Fest, communicate Steam Deck support without official verification, and set localization so the algorithm shows your game to non-English players. He also shows how to bulk-check which Steam keys got activated and how to correctly wire up macOS depots so both players and devs can download them. Practical, step‑by‑step fixes for overwhelmed Steam newcomers.
