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.'"

Some say below parameter keep GC in low pause
-XX:MaxGCPauseMillis=5000
Some say below parameter are very optimal

http://www.theserverside.com[..]d.tss?thread_id=41258&ASRC=EM_NNL_347804

-XX:CMSIncrementalDutyCycleMin=0
-XX:CMSIncrementalDutyCycle=10

Relaxing tips - http://thehousenews.com[..]%9B%E5%A3%93%E5%B0%8F%E8%B2%BC%E5%A3%AB/


積極思考能夠緩解壓力,這一點毫不令人意外。不過明尼蘇達大學卡爾森管理學院工作及組織學教授、該報告的作者之一格隆布(Theresa Glomb)說,事實證明,積極正面的思考可能比用人單位目前采取的很多抗擊工作壓力的方法都更實用,這些方法包括提供靈活的工作安排或創建新的組織結構圖,而這實際上并沒有改變辦公室的日常生活。

寫下一天中發生的好事本身就很有價值,但格隆布說,真正的影響來自寫下為何這些事會讓你感覺良好。這樣做會凸顯出一個人在工作生活中獲得的資源和支持,比如技能、幽默感、讓你感到鼓舞的家人、或是一個富有同情心的老板。 - http://cn.wsj.com/big5/20130909/eoe073851.asp?source=rss
