所以我认为同学们不要妄自菲薄,见到自己不懂的,或似懂非懂的,就认为是高深学问,畏而敬之。更不要骗自己,不懂却认为是懂。同学要问︰皇帝何来新衣了?不久前一位同学问及他高举的诺斯的某术语何解。我说不懂。我怎会不懂诺斯呢?同事十三年,好几个学期他旁听我的课。诺斯对问题重要性的感受好,这是天赋,是他的本钱,创造术语只不过是他的成名玩意,而这种颇为流行的玩意他的本领只是一般。是的,经济学行内有走不同路线的人,本领各各不同,有些成名,有些被认为是笨蛋。同学不要管这些。要管的是分析,因为这是脑子的操练,对整生的任何一方面都有好处。论分析,其中一个要点是任何术语,甚至任何一个字,其意思或理解都不要放过。坚持要知道,要明白。这样,三几年后同学会体会到学问有真假之分。是的,做学问要执着。 - http://blog.sina.com.cn/s/blog_47841af70100cw6c.html

How to communicate with difference type of learners
Active versus reflective learners: "Active learners tend to retain and understand information best by doing something active with it--discussing or applying it or explaining it to others. Reflective learners prefer to think about it quietly first."
Sensing versus intuitive learners: "Sensors often like solving problems by well-established methods and dislike complications and surprises; intuitors like innovation and dislike repetition."
Visual versus verbal learners: "Visual learners remember best what they see--pictures, diagrams, flow charts, time lines, films, and demonstrations. Verbal learners get more out of words--written and spoken explanations. Everyone learns more when information is presented both visually and verbally."
Sequential versus global learners: "Sequential learners tend to gain understanding in linear steps, with each step following logically from the previous one. Global learners tend to learn in large jumps, absorbing material almost randomly without seeing connections, and then suddenly 'getting it.'"

A outdated (1.4) , compehensive but still not really too detailed, overview of various GC tuning - http://www.petefreitag.com/articles/gctuning/

Some say following VM parameter is good enough
-server -Xmx -XX:+UseParallelGC
http://blogs.sun.com[..]/page/binublog?entry=java_tuning_for_xml

Some say is useful if you have huge memory
-XX:+UseLargePages
http://blogs.sun.com[..]dagastine?entry=java_se_tuning_tip_large

Some say below parameter keep GC in low pause
-XX:MaxGCPauseMillis=5000
Some say below parameter are very optimal
-XX:+DisableExplicitGC -XX:+UseConcMarkSweepGC -XX:NewSize=1200m -XX:SurvivorRatio=16
http://www.theserverside.com[..]d.tss?thread_id=41258&ASRC=EM_NNL_347804
Some say those parameter is good
-XX:+UseConcMarkSweepGC
-XX:ParallelCMSThreads=1
-XX:+CMSIncrementalMode
-XX:+CMSIncrementalPacing
-XX:CMSIncrementalDutyCycleMin=0
-XX:CMSIncrementalDutyCycle=10
http://blog.mikiobraun.de/2010/08/cassandra-gc-tuning.html

Just in case anyone is curious, the flags enabled by -XX:+AggressiveOpts in JDK 1.6.0_25 are:

-XX:+EliminateAutoBox
-XX:AutoBoxCacheMax=20000
-XX:BiasedLockingStartupDelay=500
-XX:+DoEscapeAnalysis
