Simulation vs. Experiment

During a gathering with my research friend, we touched a little on this topic. Simulation vs. experiment. I definitely agree that these two are totally different animals, and now I think of one definition to make this difference clearer.

What is experiment: Try to eliminate all factors that could unexpectedly inference the outcome, and to keep a full control on some factors as determined by our parameters setting.

What is simulation: Try to create all factors that assemble our expected outcome, and to introduce some real world (random) factors to reproduce the nondeterministic scenario.

If you like my thinking, you may like the following linkage as well.

Experiment shares the art of photography. If you take a picture without a careful thought, very easily you get a picture with too much details and your focus is washed out. A simple skill may give you a better picture --- The eye of elimination. Eliminating what you don't need, and let your focus stands out.

Simulation shares the art of painting. If you draw without a careful thought, very easily you get nothing. A simple skill may give you a better painting. The mind of creation. Creating your focus first, and give your focus some decoration to make the scene complete.

Hope you like it~ ^^

Interesting, I know photography, and I know simulation, but not the other two.

Academic mode vs. commerial mode

I come to school at 9am this morning, as I didn't sleep...

Anyway~ I get a trial run being a full-time student today~! Feeling super good and I am back into my "academic mode."

So, what do I mean by academic mode?

Commercial mode:

• If I wake up too early, I go back into my bed straight
• Try forcing myself to work at 9am, but end up reading news or surfing webs
• No matter how fast I can get done my lunch, never go back to work during lunch time
• Try forcing myself to work right after lunch, but end up reading news or surfing webs
• Slowing down myself gently when 6pm is coming. I guess I am slowing down so nice that the rate of change of speed is sharp 0 at sharp 6pm!

Academic mode:

• If I wake up too early, just leave and go back school straight
• Try telling myself reading news is important, but end up working on my manuscript at 9am
• No matter what, back to my lab right after I finish my lunch
• Try telling myself reading news is important, but end up working on my manuscript after lunch
• Always want more time. Keep working till I think I am enough for the day
• Something my brain just running all over the night, thinking about what to do on the next day

I love my working mode now~! ^^

Look forward to my full-time study life~

Things are all settled down. I am ready to leave my job

I decide to leave my job on Jan 31. Since February 1, I will give all my time and effort toward my PhD study.

• The decision was made during mid-October, right after I came back from the annual academic conference CCCN'09.
• Graduate school approved my application to be a UGC-funded full time PhD student in the earlier December. In other words, I secured a funding and I was ready to go.
• On Dec 24, I submitted a resignation letter to the company's supervisor.

About 20 months ago (May 2008 to be exact), I decided to do the PhD study in part-time mode and joined this company. Now I fall-back everything~!

My mindset have been changed during these 20 months of work. I don't know where should I start if I have to explain everything in details....

Anyway, it doesn't seem to be a good idea using my own resources (time, effort, opportunities, etc) to please others~ Looking good among my peers is really cool. I tried, but I am tired about tracing so many vague definitions of "looking good."

It is now the time my vague definition of "looking good" comes to the surface!! Let me focus my own toward my perspective of looking good.

I am sorry that I had been long treating research as my interest only. Now, research is not only my interest, it is going to be my bowl of rice.

I admit that counting my entire life on research is risky. But now I am on my own, I guess I am ok to take risk!!

In the CCCN' 09 conference, I found most of the research students had advanced a lot from the past year. I am the one who lacked behind the most.

I should thank my job in fact. Interestingly, my current job allows me to see more the connection between academic research and engineering projects. It allows me to know more about equipment vendors and what their PhD staffs are doing.

I am looking forward to my full time PhD study~ I am excited about having an entire control on my schedule. Following is part of my todo list~ ^^

• Put my entire effort to work out my deflection routing ideas
• Read research journals more often
• Read telecomasia (or similar articles) more often
• Learn to play a music instrument
• Have more time to sleep

I miss all the friends I made in this company. I learn how does an ISP work from inside-out. I see what does it mean by inter-personal communication skills. I guess the working style from company and from academic are going to have a good mix inside my body, and I should be able to due with people with even more different background or types.

Friends~ I know some of you may not completely agree with my decision. Nevertheless, I am not born to be a perfect guy, and certainly I have to make some mistake during my life. Forgive me, and give me your support as a kind of sympathy. If you second my decision, please keep it no matter what. I am not sure if my act is worth to be seconded continuously! I won't change again as I can't go back anymore.

Go ahead~!!!

幫公司搞X'mas Party好開心

的確有好多個意想不到

- 意想不到大家邊開會邊搞笑, 就連HR都比我地童化埋!
- 意想不到原來收買佬哩個遊戲, 會帶黎咁高漲既氣氛!
- 意想不到3位MC真正on-air時既表現會比排練時好咁多!
- 意想不到其實成個event都搞得幾體貼!
- 意想不到原來我都幾enjoy今次搞party既過程!

好開心可以幫Kelly手搞個big game, 好開心可以同MC組一齊諗script一齊做好件事, 好開心HR負責既同事會千叮萬囑我地「當日唔好淨係掛住幫自己果part呀!」, 好開心爆36'波原來係咁high既一回事!!

我相信哩次幫手, 會係我係哩間公司一個最美好既回憶呀 ^^ 其實瞓身做一件事, 結果係自己開心, 已經好值得滿足呀

好朋友! be tough!!

最近身邊都有好幾位好友無情白事陷入情困，追緊人也好，拍緊拖也好。

好希望可以為你地帶黎一點支持 ^^ 雖然你地可能feel唔到，但其實總有人默默為你地擔心為你地著緊架!!

Be tough my best friends!!!!

Understanding climate news is a daunting task!

It is a hard job to keep up with the climate news generated from cop15.

I have, at the time of writing
- 65 cop15 news unread
- 132 environment news unread from REUTERS
- not fully understand the background and story of UNFCCC
- lack of political sense on the negotiation agenda for both the rich and poor counties
- not enough time to do reading

If I can consume the whole story, I feel I have the responsibly to distribute and educate my dear friends and the youth community. The leaders of the World now struggling to come to an operational consensus because they are protecting the jobs and life on their home land.

If fact, I believe we can do something to easy our leaders of the World, giving them a clearer way to an operational accord to combat climate change.

Hope I can have a more complete picture on UNFCCC soon ^^

開始掌握到如何走進單身貴族一群

好高興，今日可以認識到新朋友~!! 絕對要多謝Dickson既邀請，交友圈子得而擴闊~

越係諗住單身不幸，越唔識去enjoy每一個交朋友既機會。反而投入單身生活，會對貴族一詞多一點點了解。

唔知關唔關唔夠瞓一事，突然唔想對每一個異性都展開「持續可發展性研究」，而一切都要依自己既大局為重 --- 唔好比人搵苯，唔好比人搵苯，唔好比人搵苯，唔好比人搵苯，唔好比人搵苯 ... 我咩都無，就係時間好__多，哩d係我唯一最有價值既資產，唔可以再比人搵苯

時間要用黎寫paper
時間要用黎contribute ns-3
時間要用黎從建同中學老友既關係
時間要送比對我好既朋友
時間要用黎搞活動, 廣交新好友
時間要用黎強身健體, 行山踩單車睇戲
時間要用黎好好瞓覺 (放到咁後...?)
時間要用增廣見聞 --- climate change議題, 學樂器
時間要用黎做義工!!!! 哈哈

但時間唔係用黎白費響d無結果既事情上

不過我自身控制能力太低...... 哩方面我要進步下!!

努力呀dear自己!!! ^^

好開心

我相信我又做左件好事 http://bit.ly/4MsITA

有想法既人要勇敢D呀!!!! ^^

義工@親子活動後感

今日義工幫Nam手帶親子活動, 帶sharing。活動後聽完主任同吹吹對我既觀察, 發覺我既轉變實在太大.... 當年親仔camp開著個AVB mode, 幾廿個小朋友飛樸上我背隻玩人肉層層疊; 相比起今日開著個返工mode, 帶組帶遊戲等交齊功課後與小朋友hihi byebye, contrast實在太大~

有時我諗野真係好極端, 一係黑一係白, 一係AVB mode for everything, 一係就返工mode for everything。

最有趣既係, 不足幾個week前Nam家姐提點我，商業社會做事，態度要商業d (濕9d)，唔可以太過為人切想; 今日中心主任+吹吹比我既提點，令我發覺自己似乎失去左我當年果種自我享受感。一個100% exact錯配...!

學習做一個毒男

老老實實，唔可以成日痴女仔啦....!! 我越黎越性別歧視，覺得女仔都係棍騙人既動物，騙財既又唔會蠢到黎搵我，但騙時間既就一街都係。當然，都要我夠低能，騙案先可以成事。

小學既我，朋友既男女比激低，小五小六女同學生日，一張大合照廿個人男仔五個都無，應該係因為咁，我到左中學，主動埋女仔堆玩一D都唔覺尷尬。

IVE再上大學，圈子不斷行業化。男性行業，自然男女比激高，男性朋友多，但我繼續發姣，認女唔認仔。

今時今日單身啦，問題一次過浮晒上水面。身處男性行業十年八載，朋友跟本男多女少，random搵個朋友去行山去玩去睇戲，逢男既都有種「奇妙」既回應。「做咩??」「我唔想聽你訴情苦WO」「你轉性呀?」「無女WO」之如此類。

十幾歲時，我day day走去搵女仔過日仔，今日要學下同自己友相處。

不過到廿幾歲既今日，反而身邊既男仔day day諗計走去搵女仔過日仔，顯得我好似嚴重欠缺童年咁款!

要學下做毒男，反正我身邊實在有太多毒男可以form反一組support group!!

• 中學同學葉兄識左十幾年，相依為命下囉要。今日先同佢傾去電影中心睇戲，佢話我開著晒turbo走毒男路線，咁咪好囉，大家同路人!!
• 要主動d搵多d活動，我朋友唔少，但傾到計既黎黎去去得果幾個，而家時間多的是，再唔打友誼牌我就真係isolated架啦
• 儲錢!! 搵葉兄去台灣旅行，識台妹!!

公司有個幾識關心人既男同事，有時見到我都問我一句「點呀，戒左毒未呀你」^^ 本來佢問親哩句，我都好想同佢學習下點戒，但而家，算啦... 反正返埋學校後，情況只會更嚴重，無得戒架啦。

女朋友哩個職位，我未至於好清楚係要一個點樣既人，但起麻我會知道，我需要一個可以同我心連心既人，令大家都會心境甜蜜。我亦起麻知道，哩個人唔會下意識地為一已私欲而耍手段，令我每兩小時就討厭佢120分鐘。我更起麻知道，哩個人會帶有女性韻味，亦帶有男性剛強。我再起麻知道，哩個人未出現。

慢慢等吧。係我一大炸閒雜事中，首要做既係友誼救亡工程。

人生又一大事

我收到學校寄黎既offical letter啦!!!
