The High Cost of Redundancy: A Forensic Analysis of Oracle ASM Design Flaws
This report conducts a forensic-level deconstruction of Oracle ASM to argue that the technology suffers from fundamental design flaws.

仲家帝国的军事解剖:袁术阵营军制与战斗力虚弱之深层研究报告
汉末三国时期,群雄逐鹿,袁术作为“四世三公”汝南袁氏的嫡系传人,一度坐拥当时最富庶的南阳与淮南之地,兵多粮足,更率先称帝建号“仲家”。然而,在历史记载与后世印象中,袁术军的战斗力却呈现出与其政治声望极不相称的羸弱:对曹操屡战屡败,对吕布以众击寡而溃,最终在众叛亲离中走向覆灭。本报告基于《三国志》、《后汉书》、《资治通鉴》等可信史料,旨在对袁术阵营的军事制度(军制)进行详尽的解构与重组。报告将超越表象的战役胜负,深入剖析其兵源构成、指挥体系、后勤机制以及地缘战略等维度的系统性缺陷。研究发现,袁术军的“弱”并非单纯的兵员素质问题,而是其“部曲私兵化”的过度膨胀、掠夺式后勤模式的不可持续性、以及政治野心与军事能力严重倒挂所引发的系统性崩塌。袁术构建了一个外表庞大但内部缺乏向心力的军事怪胎,其军制在面对曹操等实行“法家式”军事改革的对手时,遭到了维度的降维打击。
