McDonald's has confirmed the McRib, its boneless pork sandwich topped with barbecue sauce, onions and pickles, is returning to menus in select U.S. cities this week on a limited basis. A crowd-sourced locator map is being used to help customers find participating restaurants carrying the item.

Engineer's 'Brain Sandwich' method proposes bracketing AI coding with human review

A blog post recounts a framework shared by an engineer named Emily for working with AI coding tools, dubbed the 'Brain Sandwich': think through the problem yourself first, delegate implementation to AI, then personally review and refine the output before sending it for review. The approach is offered as a counter to engineers fully outsourcing tasks to AI, a practice some reportedly call a 'Meat Proxy'.

Android's hidden developer setting can speed up phone animations

Android devices include a developer options menu, accessible after tapping the Build Number field seven times in Settings > About, that lets users adjust animation speeds. Within this menu, setting the Window animation scale, Transition animation scale and Animator duration scale to 0.5x makes system animations play twice as fast, a feature that has existed since Android 4.0.

Three Mathematicians Prove Long-Standing 2004 Graph Sandwich Conjecture

A team of three mathematicians has finally proven the 2004 'sandwich conjecture,' which claims that any sufficiently large graph of interest can be mathematically bounded above and below by two simpler, well-understood random graphs. The proof, completed in 2025, resolves a two-decade-old open problem in graph theory by pushing existing mathematical techniques to their limits.
