Parse notes
Terraria and Celeste were successfully ported to WebAssembly (WASM), allowing them to run in web browsers. The process involved decompiling the C# code, configuring it for WASM, and resolving compatibility issues with the FNA engine, audio libraries, and threading. To load mods, they made the game binary load at runtime instead of compiling it with the project and used the Everest mod loader.
A slow database query calculating user credit balances took down Placid.app when high-volume API requests triggered thousands of concurrent executions of an expensive query that should have been cached. Multiple workers tried to calculate the same user's balance simultaneously and the load ballooned. This caused a cascade of failures, timeouts, and blocked queries that eventually froze the system.
TanStack Router is a great routing solution for React apps due to its focus type safety and developer experience. The router has features like type-safe routing parameters, validated search params, and fine-grained subscriptions to prevent unnecessary re-renders. It supports both code-based and file-based routing and has integrated support for React Suspense.
Database architectures have evolved from the unified systems of the 1970s to the specialized OLTP and OLAP systems that emerged due to conflicting workload demands. HTAP (Hybrid Transactional/Analytical Processing) became popular in the 2010s to bridge the gap between transactional and analytical systems. However, HTAP as a single database failed to gain widespread adoption due to the dominance of cloud data warehouses, faster hardware negating the need for distributed OLTP and organizational silos.
A pen and notebook are better for problem-solving and creative thinking than a computer. Stepping away from the computer allows for more thoughtful design, bug fixing, and understanding of code flow. Writing and sketching turn abstract ideas into tangible artifacts, revealing gaps in knowledge.

While AI coding tools get most attention, AI code reviews are having more immediate impact by automating routine checks like coding conventions and test coverage. AI will become better at reviewing existing code before mastering autonomous creation of complex systems. The key shift is moving from "approve first" to "possibly revert later" workflows.
The core Go team contracted an external security firm to audit Go's core cryptography packages, resulting in only one low-severity finding. The results validate Go's strong cryptographic security practices and the team also explains other security enhancements coming to Go.
AI coding agents can be parallelized using Git worktrees to improve throughput and control over a codebase. uzi is a CLI tool designed to automate the orchestration of multiple AI agent worktrees. It makes tasks like prompting, executing commands, and managing agents easier.
JavaScript-based "proof of work" systems, used to deter LLM scrapers, pose a dilemma because while scrapers could dedicate CPU time to solve these challenges, doing so exposes them to potential exploitation by malicious actors injecting other JavaScript for purposes like cryptocurrency mining or CPU resource draining.
OSV is a high-performance CSV parser for Ruby supporting both hash-based and array-based row formats with various configuration options.
Using "fast-math" compiler flags can speed up math computations at the cost of accuracy and potentially introduce subtle and hard-to-debug errors by violating IEEE 754 floating-point standards.
Teachable Machine is a web-based tool that allows anyone to quickly and easily create machine learning models to recognize images, sounds, and poses in a no-code way.
