"A CALCULATOR APP? ANYONE COULD MAKE THAT."

Creating a seemingly simple calculator app is far more complex than it seems. The Android calculator's accuracy was achieved through an engineering feat led by Hans-J. Boehm, who used a system combining rational arithmetic and recursive real arithmetic (RRA). This approach balances the need for precise calculations with practical computational limitations, dynamically switching between methods depending on the complexity of the expression.

HOW TO ADD A DIRECTORY TO YOUR PATH

This is a comprehensive guide on adding a directory to your shell's PATH environment variable. It goes over how to identify your shell, locate the correct configuration file, and determine the directory to add based on the program's installation location. While the process seems obvious at first, people commonly run into various “gotchas” that are detailed in this article, like running the wrong program version, duplicate PATH entries, and history loss after PATH updates.

NASA HAS A LIST OF 10 RULES FOR SOFTWARE DEVELOPMENT

NASA's ten software development rules were designed for high-stakes embedded systems, but aren't that flexible. They're probably too restrictive and impractical for applications beyond spacecraft software, especially in languages offering better abstraction and error handling. Many of the rules, like limiting function length and forbidding dynamic memory allocation, make code readability and maintainability worse.

WE WERE WRONG ABOUT GPUS

Fly.io's investment in GPU-enabled machines for AI/ML inference was unsuccessful, mostly because developers liked readily available LLMs and APIs over managing GPUs directly. The company learned that focusing on core features preferred by a wider dev base was more important overall.

PRODUCT DEVELOPMENT PROCESSES YOU MIGHT NOT HAVE HEARD OF

Beyond Scrum, Kanban, and Scrumban, there is also ShapeUp (a 6-week cycle emphasizing thorough planning before building), Plan-Build-Ship (a streamlined waterfall approach), and GSD (Get Shit Done), popularized by Shopify. Some of these approaches may better suit startups or projects needing quick pivots, or vice versa.
