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

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.

Turning off power save mode on the CPU reduced brought the max latency from 11 msec down to 8 msec.

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

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.
