From Content to Structure: A Low-Cost Approach to Blog Context Evolution
1 Why I Started to Care About “Structure” As the number of blog articles increases and the content gradually spans different fields, I began to vaguely realize a problem: these originally independent articles are slowly turning into a pile of information that is “difficult to reuse”.

Electric Shock is Not for “Restarting the Heart”: The Truth About Defibrillators and Pacemakers
1 Preface I believe everyone has seen a scene in movies and TV dramas that has almost become a “conditioned reflex”: on the monitor, the ECG suddenly flattens into a straight line; the atmosphere suddenly freezes, the doctor shouts, and the defibrillator comes into play; “Clear!”—after the electric shock, the ECG waveform miraculously re...
