Importance of finding out your Signature Strengths - http://traderfeed.blogspot.com.au[..]ature-strengths-and-trading-success.html

索托說:“你應該從改變行為做起,接下來,如果你能長期保持這種新行為,這種行為就會被鎖定下來。”他說,如果能獲得心理治療師的指導,你可以在幾個月之內看到持續的變化。你也可以學著自己管理你的性格特征,只是要花費比較長的時間。
那么,你應該從哪做起呢?加州德爾馬(Del Mar)的心理學家理查德‧萊瓦克(Richard Levak)表示:“首先,我們必須認識到性格中有哪些因素對我們構成了影響。如果我愛發牢騷,好爭辯,還有點多疑,我總是因為跟同事吵架,老是責怪別人而被解雇,那我就必須意識到得改變一下。”
萊瓦克說,這和糾正暴飲暴食這種壞習慣相似。要想減肥,你就得認識到自己什么時候以及為什么會暴飲暴食。萊瓦克博士表示:“如果你有戒心過重和好斗的傾向,你就要對自己說:‘好的,當我老板過來跟我說話,而我立馬感覺老板在挑我的刺,想要自我防衛的話,那我就是反應過激了。’讓自己冷靜下來,不要爭吵。”
不要把期望值定得太高。耐心一些。索托博士說,要把一種有意為之的行為變成習慣,需要花費很長時間。不要太擔心其他人的反應,因為你的變化通常是他們樂于見到的。

This, I find, is the single greatest impediment to pursuit of excellence: Most of us are simply too busy doing our jobs well to become truly world class at what we do. I occasionally ask traders to go back to old journal entries and tell me how much time they spent reviewing those entries and assessing their progress over the past week. In the great majority of instances, the journal entries are never revisited! - http://www.forbes.com[..]ndar-into-a-peak-performance-tool/print/

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.

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
