DEBUGGING TILL DAWN: HOW GIT BISECT SAVED MY DEMO

SQLITE ON RAILS: THE HOW AND WHY OF OPTIMAL PERFORMANCE

SQLite out-of-the-box on Rails isn't production ready. It needs some performance improvements with the help of some Ruby gems (packages) that enable immediate transactions, manage write query queues, and release the Global VM lock while queries wait for database responses. SQLite should be used in the write-ahead-log (WAL) mode and should have separate connection pools for reading and writing operations.

WHY COPILOT IS MAKING PROGRAMMERS WORSE AT PROGRAMMING

AI tools like GitHub Copilot are making programmers worse at programming. These tools can erode fundamental programming skills and create a false sense of expertise. Relying on them without a deep understanding of the code and the ability to problem-solve independently will make developers dependent on AI.

WHY NOT COMMENTS

Comments that explain why a certain approach wasn't taken in the code are valuable. While identifiers can describe "what" the code does, they cannot always properly convey the reasoning behind choosing a less optimal but simpler solution.

WHY SOME OF US LIKE "INTERDIFF" CODE REVIEW

Traditional code review systems, like GitHub, suffer from a "diff soup" problem, where multiple commits are crammed together and reviewed as a single diff. This makes it difficult to follow the evolution of code changes and leads to issues with blaming, bisecting, and incremental review. An "interdiff" approach, where revisions of the original commits are published instead of new commits, lets reviewers see incremental changes and lets authors avoid cluttering history with "fix review" commits.

SIMULATOR-BASED REINFORCEMENT LEARNING FOR DATA CENTER COOLING OPTIMIZATION

Meta has successfully used reinforcement learning to optimize energy and water consumption in its data centers. Its approach uses historical data and a physics-based simulator to train a model that determines the optimal airflow setpoint for various weather conditions.

LEADING EFFECTIVE ENGINEERING TEAMS: A DEEPDIVE

DAVID CHANG ON THE LONG, HARD, STUPID WAY

Doing things "the long, hard, stupid way" means maintaining high standards, even in casual settings. This approach, though inefficient, fosters a culture of excellence and ultimately contributes to success.

GOOGLE WILL NOW LINK TO THE INTERNET ARCHIVE TO ADD MORE CONTEXT TO SEARCH RESULTS

Google has partnered with The Internet Archive to add links to the Wayback Machine in its search results, providing users with historical context for web pages.

THE DEV TOOLS PERFORMANCE MONITOR PANEL

This developer describes how the Performance Monitor panel in DevTools helped identify and fix a performance issue in an animated spinner component, ultimately reducing CPU usage and improving the overall performance of the website.
