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。

interviewer tip


The best way I've found to interview candidate developers is to pair program with them to do real work on the actual code of the project that is hiring. If not possible, give programming exercise which is:

The exercise must involve working with current development tools.
The exercise must require the candidate to apply important features of the language.
The exercise must involve understanding and working with existing code.
The exercise must involve error handling.
The exercise must involve testing.
The exercise must offer scope for domain modelling.
The exercise must involve asking questions.
The exercise must be realistic.
The exercise must involve changing requirements.
The exercise must offer the candidate enough rope to hang themselves.
The exercise must test many different skills and practices.

A good interview programming exercise takes at least an hour. - http://nat.truemesh.com/archives/000630.html

星軌拍攝技巧 數問 -

1).數碼機因hot pixel而唔適合曝得耐...最好分開影影夠幾個鐘...咁每張間隔之間都要俾CMOS斗下氣?
有師兄 教過 分十幾張 每張 10-20min 再合成 好過 一野 暴 幾粒鐘, (菲林 令計)

2).數碼機有D人話用ISO 100、有人話用ISO 400-800好...如果用合成方法...其實係咪都係就番光害而定...定係關雜訊事?
睇天氣 , 小弟 用 o個次 用 iso 100

5).北極星仰角澳門係23度,咁香港一樣??
4季 都唔同 位置, 用星座 搵 會準確 d, e+ 係 冬季, 北極星 位置 係 獵戶座 (lei 個最易 認, 唔會 搵唔倒 ... ) 頭頂 (腰帶 致 頭頂 距離 再過 5倍左右)

附圖 係 舊年 去雲南 香格里拉 時影, 本泥想 長暴, 不過 o個晚 太涷 個人 頂唔順 要收皮 反酒店

這張是11月15日凌晨拍攝的M42獵戶座星雲, 大埔的光害較嚴重, 所以要加上IDAS V4濾鏡作長時間曝光, 分三段不同時間曝光及作Layer Masking 處理, 把動態範圍拉闊. 在月光的影下算是滿意, 希望之後可以分數晚作10小時以上的曝光並加長每一張frame 的曝光時間 (現在是5分鐘一張), 使到暗位的表現進一步改善.

distribute


In one sentence, here's why: humans are notoriously bad at keeping "self" distinct from "other". Egomania, projection (transference), and enmeshment are well-known symptoms of this problem. OK, so I hear you saying, "yeah, but what does this have to do with programming?" It certainly seems absurd to suggest that if we are bad at something we know the most about (our "selves"), how could we possibly say that we have a good approach for the programming analogues - objects, modules, etc. - http://www.artima.com/weblogs/viewpost.jsp?thread=46706

lightroom


If you using mac and like to have post editing of digital photo, Definitely worth to try:
http://www.macromedia.com[..]n/entitlement/index.cfm?e=labs_lightroom

A free (until beta period finish) competitor of Aperture. The auto tuning work excellent. However, there is no plugin yet and require highend machine to work smooth. It take 400MB RAM for just a few RAW photo and it work like a dog on my poor mac mini. This is the first time of this 5 years I wish to have a better machine

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

Efficiency - the amount of work you need to do.
Performance - how fast you can do that work
Efficiency - governed by your algorithm
Performance - governed by your data structures.
http://www.rationaljava.com[..]e-difference-between-efficiency-and.html


Turning off power save mode on the CPU reduced brought the max latency from 11 msec down to 8 msec.
Guaranteeing threads will always have CPU resources using CPU isolation and thread affinity brought the maximum latency down to 14 microseconds.

While reviewing this article, Marty Andrews pointed out an important insight: there are two ways to use a mock object, either as a testing technique or as a design technique, and the intended use helps shape the available choices.

http://www.onjava.com/lpt/a/4526

Someone post some arguement that using mock probably a bad idea , which look like a endless arguement... - http://jroller.com[..]xRuiz?entry=mocks_for_concrete_class_can

Alberto Savoia on Testing the Untestable, raise a point that mocking make testing more portable, it probably true, but database setup may be not that difficult to port. - http://www.artima.com/forums/flat.jsp?forum=276&thread=213402

A good explanation of what is courage, and the result of didn't have courage. It also mention a bit of how to bulit courage within the team, but not much about it - http://www.xprogramming.com/xpmag/NotXP.htm

A potential issue of focus too much on people, rely on few heros - http://jchyip.blogspot.com[..]12/people-over-process-misses-point.html

Our agile process requires people to spend the effort to listen and talk to each other, working closely. You have to be a people person to like it. It doesn't suit sociopaths. Accidently hiring a sociopath is going to make XP impossible. Trust me, I know. To me this is XP's fundamental weakness. http://jchyip.blogspot.com[..]12/extreme-programmings-fundamental.html
