We've reduced token costs in Cursor by 7% with no drop in agent quality. Savings came from tighter prompts, selective tool loading, better caching, and compressed file reads. https://t.co/EMNxELnfwO

Introducing Rollouts. Rollouts write a monitoring plan, then watch changes as they deploy. Deployments are verified, so regressions are caught before users see them. https://t.co/01Pgz5B6V1

Visualize Data Structures in VS Code 🤯 If you work with data structures, check out the Debug Visualizer extension for VS Code. It lets you visualize your data while debugging so you can actually watch algorithms and data structures change as your code runs. In this example, see a linked list grow node by node and watch QuickSort move values into sorted order. A great tool for learning data structures, understanding algorithms, and debugging complex code. #VSCode #Programming #Coding #DataStructures #Developer

A pull request with 2,200 files, 1M+ changed lines, and 400+ inline comments. Impossible to review? Not if you have the GitHub Copilot app. ✨ The rebuilt pull request view keeps even this extreme diff fast and smooth. 🧵

Code is the easy part: virtualize the rows, keep the DOM small, and use known line heights. Comments are harder. Their height changes with markdown, replies, expandable sections, images, and async content.

The solution was two independent geometries: • Deterministic code height, known up front • Dynamic comment blocks, measured lazily and corrected near the viewport That keeps comment reflows from rebuilding the code layout.
