Braindump is an AI game studio that lets users build top-down/2.5D games by typing prompts. It allows users to define units, abilities, and attributes, as well as populate the game map with objects and create game rules. Two challenges in building AI games were designing an intuitive user interface for prompting the AI and creating a streamlined "game API" that provides enough structure for the LLM to focus on filling in code and data.
You can use a single plain text file, structured with custom parsers to define measures, measurements to define concepts, and comments attached to measurements using indentation, for all tabular knowledge.

Airbnb improved its website's accessibility by implementing font scaling, allowing users to adjust text size independently from page zoom. Unlike browser zoom, which can create layout issues on smaller screens, font scaling only affects text elements, providing a better user experience for those with low vision. Airbnb used rem units for font sizing, as they are relative to the root element and provide more consistent scaling than em units.

A testing strategy that relies heavily on end-to-end tests can cause a lot of issues in reality. While end-to-end tests seem like a good idea in theory, they often lead to delays in bug identification and fixes, as well as flaky test results. Instead, a better approach is to focus on unit tests and integration tests, which are often faster and more reliable.
Rate limiting is used to control traffic on a service by blocking requests that exceed a set limit. Three common algorithms for rate limiting are fixed windows, sliding windows, and token buckets. Fixed windows are easy to understand and implement, sliding windows are better for high traffic, and token buckets allow for bursts of traffic while enforcing a long-term average rate.
JSDoc is used to document JavaScript packages. It helps users understand how to use your code and provides additional context within their workflow. The key is to provide clear and concise information: write succinct summaries, include accurate type information, use tags to describe parameters and return values, and provide examples for clarity.
System tests often fail to live up to their promise. They are slow, prone to errors, and rarely provide a good return on investment. While they can be useful for basic functionality checks, they are not the best tool for testing business logic or UI interactions compared to manual testing.

CPUs have multiple cache levels to balance speed and size. The L1 cache is small and fast, primarily for storing frequently used data at the byte level. The L2 cache is larger but slower. It deals with cache lines (groups of bytes) and handles most communication between the CPU core and other components. The L3 cache is even larger and slower, serving as a shared resource for multiple cores and handling less frequent requests.
Serve static HTML whenever possible instead of relying on server-side rendering to improve your personal website's performance. Optimize images by converting them to next-gen formats and using the `picture` element for browser compatibility. Also, use system fonts to avoid the performance issues of loading custom fonts and try to not have render-blocking resources.
