What is the difference of software architect from software designer? About 30k
http://discuss.joelonsoftware.com/default.asp?design.4.491003 The law of conservation of energy - If there is no work, sleep.
Money is not everything. There's Mastercard & Visa.
One should love animals. They are so tasty.
Save water. Shower with your girlfriend.
Love the neighbor. But don?t get caught.
Behind every successful man, there is a man. And behind every unsuccessful man, there are two.
Every man should marry. After all, happiness is not the only thing in life.
The wise never marry, And when they marry they become otherwise.
Success is a relative term. It brings so many relatives.
Never put off the work till tomorrow what you can put off today.
Love is photogenic. It needs darkness to develop.
Children in backseats cause accidents. Accidents in backseats cause children.
Your future depends on your dreams.? So go to sleep.
There should be a better way to start a day than waking up every morning.
Hard work never killed anybody.? But why take the risk?
Work fascinates me.? I can look at it for hours!
God made relatives; Thank God we can choose our friends.
When two?s company, three?s the result!
A dress is like a barbed fence. It protects the premises without restricting the view.
The more you learn, the more you know, The more you know, the more you forget. The more you forget, the less you know. So why bother to learn.

身處廣東香港，隨時有人會說「白蘿蔔破氣」，我二嫂因而有幾年不敢吃白蘿蔔，其實白蘿蔔破掉了內熱的污濁之氣，沒有甚麼不好。
醫書上說：白蘿蔔入肺，性甘平辛，歸肺脾經，下氣、消食、除疾潤肺、解毒生津，利尿通便。主治肺痿（肺的功能弱）、肺熱、便秘、吐血、氣脹、食滯、消化不 良、痰多、大小便不通暢。經常乾咳、或者痰濕但咳不出來，經常吃白蘿蔔會改善，脾胃虛寒的人要煮熟了才吃。白蘿蔔可以改善便秘。口腔潰瘍，用白蘿蔔榨汁漱 口。
用白蘿蔔和麥片煮湯可以去身上臉上的水腫！皮膚粗糙、有粉刺怎麼辦？用蘿蔔的葉子煮水，方法：把蘿蔔葉清洗乾淨，晾曬3至4天，將30克曬成的白蘿蔔葉放 入1升水中煮，燒開以後改成中火，再煮幾分鐘，過濾後就可以喝了，可以加一點蜜糖。如果找不到蘿蔔葉，只用白蘿蔔煮水喝，還可以改進消化，又養胃。白蘿蔔 含有木質素，能提高巨噬細胞的活力，吞噬癌細胞。白蘿蔔治急慢性咽炎，臨床發現，有些小孩經常隔幾個月就感冒、發燒，咽痛，其實是肺胃熱、毒壅在咽喉，西 醫說是慢性扁桃腺炎，經常服用這個湯可以清利咽喉把熱毒散開。我小時候因為這個問題經常扁桃腺發炎、感冒。
白蘿蔔治高血壓：白蘿蔔750克，荸薺500克，榨汁，加蜂蜜50毫升，1日內分2至3次服完。
白蘿蔔治哮喘：白蘿蔔150克，荸薺50克，豬肺75克，煮湯。

1，大葱拿手排便減肥；大葱含有豐富大葱素，刺激甲腎上腺素荷爾蒙分泌，產生熱量，因而燃燒體脂，從而消減脂肪。大葱纖維豐富，非常有利排便。大葱降低壞膽固醇，經常吃大葱的人即使是肥佬也沒有膽固醇問題，而且體質強壯。
2，大葱幫助人體自然分泌青春荷爾蒙，所謂壯陽補陰，這是任何最貴的西藥都無法達到的效果。生吃也可以調節情緒病。
3，治風寒感冒、陰寒腹痛、惡寒發熱、頭痛鼻塞、乳汁不通，二便不利等。大葱含有蒜素與二烯丙基硫醚、草酸鈣、胡蘿蔔素、維生素B、C，煙酸，鈣，鎂，鐵等，都是每日需要補充的成分。
4，預防癌症，大葱所含的果膠或有助抑制結腸癌，蒜素與硒元素降低胃液內的亞硝酸鹽含量，預防胃癌及多種癌症。
5，發汗、抑菌。發汗散熱，使黏痰易於咳出。大蒜素強烈殺菌與抗病毒，殺痢疾桿菌，殺皮膚真菌，包括香港腳、念珠菌。
6，舒張血管預防老年痴呆，促進血液循環，防止血壓升高引起的頭暈。與蘑菇同食進一步促進血液循環。
另外，葱不可與豆腐同吃，同時喝蜂蜜會腹瀉，服用六味地黃丸期間吃大葱會功效互相抵銷。
有胃腸道疾病特別是潰瘍病者少食。有腋臭的人在夏季慎食，身體虛、多汗者也忌食。過多食用葱會損傷視力。葱葉部分比葱白部分含有更多的維生素A、C及鈣。
英國威爾斯郡（Wales）的民族徽圖竟然是大葱，可圈可點。

putall can cause ConcurrentModifcationException -
http://cr.openjdk.java.net[..]ses/sun/management/Agent.java.sdiff.html Note on writing CopyOnWrite wrapper -
http://flyingspaniel.blogspot.com[..]ot.com/2010/12/copyonwrite-wrappers.html Sometime this is a bit difficult for Chinese to be a good programmer, recently some colleague and me discuss about the behaviour of this class and look like we have difficult understanding
A: ConcurrentHashMap support for locking as this is thread-safe
B: ConcurrentHashMap is thread safe for read but not for write because there is no lock, we still need to have external lock to keep it thread safe. By the way, I get ConcurrentModificationException from this before.
C: ConcurrentHashMap don't support for locking but they still thread safe for all operations, which is how "This class is fully interoperable with Hashtable in programs that rely on its thread safety but not on its synchronization details." mentioned.
Too good that we can actually take a look at the source code to see what going on nowadays rather than just guessing -
