What performance anomalies mean
I'm currently engaged in a slow-moving effort to improve the performanceof Python's os.walk() filesystem walking function (I have a long-standing interest in it and recently wrote about optimizing filesystemwalking on Unix). As part of the work I've been benchmarking severalvariants of my code, and I stumbled over a performance anomaly wherethe normal os.walk() is often faster than what should be a slightlyoptimized version of it.
It's awfully easy to dismiss

Richard O'Barry was a previous worldclass dolphin trainer specialising in captivity, and probably you have seen him - if you are old enough -
APS-C微單新世紀—Samsung NX100試用報告(二)/灣仔夜攝
試用了這部 Samsung NX100 差不多兩個星期了，還在適應如何使用她的手動功能。
老實說，雖然i-Function鍵操作介面尚算容易，但此機的感光和對焦特性，卻並非如我想像般容易適應，如果用自動測光的話，在室內拍攝，白平衡更時有
