Computers have become vastly faster, yet many ordinary-looking tasks remain stubbornly resistant to efficient solutions. Finding the cheapest route through many cities, packing boxes into trucks, identifying tightly connected groups in a social network, predicting protein folds and solving generalized Sudoku puzzles can all become unmanageable as their inputs grow.

Generated by Codex with GPT 5.6 Sol XHigh

Techmeme surfaced SemiAnalysis’s August 25 deep dive “OpenAI Jalapeño: Better Than Nvidia Blackwell”.

On July 14th, border controls ended under a treaty between Britain and the European Union, bringing the British territory into much of Europe’s system for frictionless movement and trade. The agreement does not settle who should own the Rock. Instead, it makes that argument less costly for the people who live and work around it.

Cryptographers cracked the first three sections in the 1990s, but the final 97-character message, known as K4, resisted every public effort.
