DO NOT USE SECRETS IN ENVIRONMENT VARIABLES. HERE'S HOW TO DO IT BETTER

Storing secrets in environment variables is a common practice but actually may be a security risk when secrets are poorly managed, leaked through frontend code, exposed in .env files, logged unintentionally, or inherited by child processes. Developers should try to use secrets stores instead.

SMOLDERINGLY FAST B-TREES

The benchmark matters when comparing the performance of B-trees and hashmaps. Different benchmarks show hashmaps benefit more from cache behavior and speculative execution. B-trees avoid hashmap pitfalls like flooding and rehashing, but hashmaps with additional measures for order and iteration may be easier to use in development.

THE STATIC SITE PARADOX

Ironically, professional software engineers are more likely to use simple static HTML websites for their personal blogs, while regular users are often stuck with more resource-intensive CMS platforms like WordPress. This disparity is because creating a static website requires technical knowledge and effort that many users lack, while readily available CMS solutions are much easier to use (even though they are more complex under the hood).

A MODEST CRITIQUE OF HTMX

htmx is an open-source front-end JavaScript library that extends HTML with custom attributes that enable the use of AJAX directly in HTML. While the core concept of htmx is appealing, its implementation is more complicated because of issues with inheritance, state management, and integration with other libraries like React. For example, htmx's reliance on replacing DOM elements wholesale causes problems with maintaining browser-local state and conflicts with libraries like React that manage their own state.

ON THE NATURE OF TIME

From a computational perspective, time is not a fundamental coordinate but rather a reflection of the universe's computational processes. This idea is supported by the concept of computational irreducibility, which states that the only way to determine a system's future state is to trace through each computational step. Time, therefore, becomes a robust and irreplaceable element of our experience, reflecting the fundamental nature of computation.
