When XP says "go for the simplest possible design", what does that mean?
1. Simplest possible design to IMPLEMENT?
1. Simplest possible design to UNDERSTAND LATER?

An thread discuss how far should we go. Seen most people agree what should be done is "Simplest possible design to TEST and IMPLEMENT"

* The name of the test should describe the requirement of the code
* There should be at least one test for each requirement of the code. Each possible path through of the code is a different requirement#
* Test the goal of the code, not the implementation

http://googletesting.blogspot.com.au[..]esting-on-toilet-test-behaviors-not.html <- Test behaviour, not method. This will make your tests more resilient since adding new behaviors is unlikely to break the existing tests, and clearer since each test contains code to exercise only one behavior.

performance


http://highscalability.com[..]6/big-list-of-20-common-bottlenecks.html

Nothing specific, mostly code clean up, refactoring and simplification, the performance boost was a surprise. <- This is a good one - http://bad-concurrency.blogspot.com.au[..]12/07/disruptor-v3-faster-hopefully.html

Is there anything we can do about this when designing algorithms and data-structures? Yes there is a lot we can do. If we perform chunks of work on data that is co-located, and we stride around memory in a predictable fashion, then our algorithms can be many times faster. For example rather than using bucket and chain hash tables, like in the JDK, we can employ hash tables using open-addressing with linear-probing. Rather than using linked-lists or trees with single items in each node, we can store an array of many items in each node. - http://mechanical-sympathy.blogspot.com.au[..]emory-access-patterns-are-important.html

Skip lists are used instead of b-trees because b-trees don’t scale. - http://highscalability.com[..]ast-mvcc-inmem-lockfree-codegen-and.html

Beware about the performance issue of static initalization - http://stackoverflow.com[..]-cause-problems-with-multi-threading-how

Experiment show why arraylist is better in most cases - http://www.javaadvent.com/2013/12/arraylist-vs-linkedlist.html

他在公司的名言是「When you give, you get」。他在上海成立科研中心,大方讓上汽參與,他認為各懷鬼貽的氣氛不可能做出成績。合資公司理論上是獨立個體,合資公司員工應把合資公司利益放到最前,而不是自己原屬公司的利益,但很少人做得到。慢慢下來,上汽也逐漸對墨菲產生尊重。

在美國和上海工作過的GM員工,指上海GM的工作氣氛跟美國截然不同,甚至認為上海GM形成一套自己的文化,這套文化建基於信任。墨菲跟員工打成一片,工餘在家中安排活動,中美關係罕有地融洽。 http://www.thehousenews.com/finance/由傲慢製造的優秀企業/



10. 永遠記得,做出決定前要先綜觀全局。

9. 否定別人跟切換開關一樣容易。但你最好拼死抵抗這種衝動,因為你也曾經做過蠢事。你做過爛決定,然後學習、成長,別人也一樣。

8. 掃地、擦桌、關燈。哪裡有漏洞要補就去補——即便那很瑣碎、沒人會注意。你必須做這些事去造福你的產品、你的公司,以及所有你們團隊共同打造的,令眾人驚艷、神奇的事物。

7. 你無法做所有的事。閉上眼睛,向後仰倒,學會信任。

6. 顯然有某種更為有效的方法能處理你正在做的事。是什麼呢?在每天回家的路上反覆思考吧。

5. 找出總是在依賴你的人,想想要怎麼做才能協助他們,讓他們自力更生。或許你覺得當個壟斷市場的鮭魚供應商很重要,但如果小鎮的所有人都學會捕魚,便能將你解放出來去做別的事。像是學習種小麥,或是如何馴服那些可愛的小狼。

4. 別說任何對當下討論沒有貢獻的話。你的聲音並非悠揚到絕對必須被聽見。

3. 做得出最好的決定比不上處在得以確保做出更多最佳決定的流程。

2. 就像你經常發表意見那樣,多說感謝和鼓勵的話語。

1. 最重要的是:永遠要掃除障礙物。那怕只是玩玩手指、看看窗外的雲,也別讓你那愚蠢、幼稚的自我阻礙團隊前進的腳步。

column-db


Normally, we store object like

1,Smith,Joe,40000;2,Jones,Mary,50000;3,Johnson,Cathy,44000;

However, some say store as

1,2,3;Smith,Jones,Johnson;Joe,Mary,Cathy;40000,50000,44000;

is better for many cases...

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.

Noel Coward - "If you must have motivation, think of your paycheck on Friday."

Malcolm de Chazal - "Monkeys are superior to men in this: when a monkey looks into a mirror, he sees a monkey."

Money can't buy love, but it improves your bargaining position. - Christopher Marlowe.

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
