memory


These 3 Hacks Will Make You Remember More - https://betterhumans.coach.me[..]will-make-you-remember-more-b30a3d9b3136

When trying to memorise new material, it’s easy to assume that the more work you put in, the better you will perform. Yet taking the occasional down time – to do literally nothing – may be exactly what you need. Just dim the lights, sit back, and enjoy 10-15 minutes of quiet contemplation, and you’ll find that your memory of the facts you have just learnt is far better than if you had attempted to use that moment more productively. - http://www.bbc.com[..]effortless-way-to-strengthen-your-memory

This one is funny: "Distract yourself. You might feel like you’re being super productive and focused by sticking to your work, but you’re less likely to recall it later." - https://medium.com[..]-and-it-can-actually-be-fun-99a9c9b95d5b

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.

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

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.
Guaranteeing threads will always have CPU resources using CPU isolation and thread affinity brought the maximum latency down to 14 microseconds.

7. I think I know why I admire micro-ISVs.

Some of my fascination with micro-ISVs is rooted in my wonderings about the path of my career over the long term.

When I was 22, I believed that I could write code until age 65. I saw no reason why I could not be a software developer for my entire professional career. Some folks told me that being a coder is a burnout job, but I didn't believe them.

I am 36 now, and I think I have a better understanding of things. I am starting to realize that someday I may actually want to make a career change. I am trying to picture myself running an ISV when I am 55, but I just don't see it. Running a company can be awfully stressful sometimes. Will I still want to be doing this in two more decades?

My prospects for a second career are bleak. The cold reality is that I only know how to do one thing. Instead of looking for a second career, maybe I should be looking for a way to stay in software.

This is one of the things I like about micro-ISVs. The lifestyle looks very different. The workflow looks like it might be a lot less stressful. Running a micro-ISV looks more like a marathon and less like a sprint.

At my recent lunch with Thomas Warfield (Pretty Good Solitaire), I asked him if he thought he could still be running his micro-ISV at age 50. He said yes. Warfield is 40 now, so this is not the perspective of a naive young person just getting started. I believe him, and his answer makes me wonder if somebody I will be running some sort of a micro-ISV as my full-time job.
