救生員班

話說今晚要交心得,好久沒踩死線趕作業了(雖然最近應該會有一些)
救生員班心得
自強二 8 
  會來參加救生員班是個巧合,就跟認識救生員班的同學教練一樣,真的是非常巧,所以跟同學與教練們相聚的緣分也顯得特別珍貴。在大學參加社團的時候,曾經有幾位台大的朋友是水協的救生員,曬得很嘿,也很壯,那時候常常聽他們說起就生員的訓練如何精實,總想說哪天有機會也來試看看。前陣子因為公司比較閒,有時間逛fb,無意間看到一個系上游泳校隊的學長要組隊參加泳渡外木山,之前兩年跟朋友去游了日月潭,雖然很暈,但也很好玩,總在想哪天有機會要來參加海泳試試。跟學長也不大熟,就又找到了之前幾個一起游過日月潭的朋友報名參加!但因為大家都四散各地,就各自到家裡附近的游泳池練習。
  自強游泳池離家不遠,從小就常來這裡戲水玩滑水道,知道這裡有深水池,但小時候總不敢下去,那時身水池還沒有淺水區。在這裡參加了初級班(?),浴巾還在,但上了什麼就不大記得了,今天上課看到一旁的初級班再練打水,似乎有勾起一點點的回憶。一次高中的時候鼓起勇氣到深水池游泳,那時泳技很不好,只游了25公尺就沒力氣了,在游泳池裡掙扎,但救生員也沒看到,後來面勉強回到池邊。之後很長的一段日子都很少回中和,也沒再回來游過泳。今年來的時候是五月初,水才放沒兩天,還留著地底冰冷的溫度,下水真的需要很大的勇氣,買了本月票,打算天天來練習。游泳的時候覺得很有趣,旁邊似乎有一群人在上游泳課,幾乎都帶著吉美建設的泳帽,後來才知道是紅會的同學們在上姿勢矯正班。在理事長的推薦下,參加了姿勢矯正班,也認識了總教練,預報了救生員班。
  救生員班上課的課程其實跟我一開始想的差蠻多的,雖然都有按著課表交,一開始想來精進泳技,但加入了之後才發現上的課都跟游泳沒甚麼關係,除了救生四式以外。反而教了許多在水中自救與救人的方法,踩水也練了很多,雖然到現在還是沒辦法掌握秘訣,只要一把手提出水面,不用多久腳就開始無力了。上了救生班發現,其實到水裡也不一定是要一直往前游,其實一直往前游也是蠻無聊的,以前都只會由自由式,上了矯正班游了很多仰式覺得蠻好玩的,即使游得很慢又東倒西歪。在救生班的測泳,抬頭蛙,抬頭捷,水中帶人,防衛,解脫,起岸,都是在水裡的遊戲,在操作的過程中一樣要保持放鬆的狀態身體才浮的起來。這種組合非常微妙,要操作特定的技術同時又需要放鬆,有點慶幸但也不幸我還長的蠻高的,有時候操作的時候可以偷偷踩在池底,但這樣水性就不如踩不到池底的人進步的快,如果能在五米池裡訓練應該會更刺激。許多的操作都需要與同學互相練習(演戲),對於平常總是接觸電腦的工程師來說,能有機會跟人面對面接觸時在是難能可貴!扮演究者可以磨練技術,藉著扮演溺者可以體會溺者的感覺,讓我們在救人時更有同理心,也學會放鬆。
  星期天的碧潭戶外課也令人印象深刻,再深不見底的水域裡待這麼長的時間,還要是應忽冷忽熱的水流,操作各式各樣的動作,有的時候踩水才到沒力,身體還是會不由自主的緊張僵硬起來。但有趣的是,平常在游泳池總覺得男生們的泳技似乎比女生好一些,但在碧潭踩水的時候,似乎是女生答數的聲音大了一點。在操練完之後還有教練們準備的好吃豐富的點心。緊接著下午更精彩,操作救生板,魚雷浮標與翻船。看教練作得輕鬆容易,自己實地下水才知道事情不是憨人想的這麼簡單!可惜後來突如其來的傾盆大雨,讓大家提早打包回家。但也見識到大夥臨危不亂,團結一致的力量,回家打開背包,在如此的慌亂之下,背包裡的東西竟然都沒被大雨打濕!真是太神奇了!

  最後我覺得參加救生班最難的就是時間,每天都要起個大早,操完課(雖然我覺得教練都很好心,沒有真的非常操)又要去公司上班,在起床時真的需要很大的決心。但一想到有趣的課程,教練,與同學們,即使前夜到兩三點才睡,早上五點還是會準時起床的!感謝辛苦的教練們與親愛的同學們!

reading The Mythical Man-Month

I've go very slow because i was always distracted. And because my poor English, I can't study this book without my computer

some note
1. about the schedule of programming(p20)
1/3 planning
1/6 coding
1/4 component test and early system test
1/4 system test, all component in hand
and the delay of rear process will be a disastrous. we will not have enough time to delay our dead line. And the cost-per-day at the end of the project is highest.

interview of 凌 巨

it's in 八德,seems far, but not so far, just 20 minutes drive from home
we have the interview at 9, such early
there's guardroom where i need to exchange the ID, the reception desk is hold by two young lady (the reception desk is used to hold by men) the company is in the 華 映's manufacturing park, which is too big to find 凌 巨inside (i luckily glimpsed a map near the guardroom so i can found the company). the parking area(says supplier only) is 5 min walk from the main building.it didn't smell good when walking in the park ><~
i need to take off my shoes when entering the lobby, the lobby wasn't luxurious but the girl at the reception desk is friendly and pretty, she led me to a meeting room and called the hr here. i waiting in the meeting room for about 10 minutes. i forgot to bring by book inside, it a boring wait....the hr came, she it pretty, too (XD so it's a good day), and she comes alone, i used to meet some adviser in the interview so we can talk about the job, but with a hr, i can just talk about pay... yeah, she have briefly introduced the company, the history (it's a subsidiary of 華 映now), and ask if i have any question
the interview was very short, just took 30 minute. but their paid is good, 45k is no problem, include free dormitory ,free shuttle bus to Taipei, 50NT subsidy each lunch
oh! this interview is just phase 1, hr will assign the suit job by my specialty, and arrange for the phase 2 meeting with my future adviser. it will take 2 week...(there's nothing about the brief i prepared last night... i should not stay until 2 for it)

prepare the interview of 凌 巨

it's not a subsidiary of 華 映, they just bought a factory from HuaIn, 凌 陽 hold a lot of share of it. I finally recived an interview inviting letter this morning, they sent it after 6pm yesturday@@... very late, they should had sent it two days before. thier should be lots of candidate. they ask for a resume, transcript and a report of TFT... wow! it takes my whole day but still haven't finished, but it did expand my view

rejection from 和 椿

i got a thank u mail for 和 椿
although i'm not sure will i join the company if i get the admission, but it still make me disappoint, people don't like to be reject (so don't ask for something u don't really want)

value thing

today i took the TED talk "Amanda Palmer: The art of asking" with my lunch, I can't understand all but she did make me think about what is worth to be paid. her job is a statue, provid direct contact. she made some(quite much) money from if by "ask" people to help during their contact, and she want to tell other artist not be afraid, not to be shame when doing so, she ask her fan to pay for her music ( you can download it without pay), it work, how could it happen!? some people tell her to "take a job", but she's doing her job, isn't she? Should a job really produce something? Should a job include join a company? if we can produce good much more eazier from industrial revolution, and we can get information eazier from information revolution, what should we exchange in the morden world?
    it's strange that we have so many people get no job, but still many people work too much. there is still lot of thing to do in our society, how could people wan't to work but have nothing to do? is our world justic enough? our goverment always have low efficency, whenever we ask the goverment for help, they respond really slow with the excuse of not enough manpower. so why not get enough man power?

swollen eye

last night i felt my right eye swollen, and a little nausea. I'can't keep watching the project screem when i was in 房市 class. I thought that's because I didn't have enough sleep and decide to go bed earlier this night(but actually i do some exercise after school and went on facebook, hance actually slept at around 12, without taking shower..)
this morning, i've planed to jog, but my eye still swollen after 7 hour rest, I didn't go jogging. i checked the possible reason of  swollen eye, found it could be glaucoma. i have deep myopia and my brother has glaucoma, so i have a high risk of it. it could make me blind! i borrowed my collage's mortocycle to ride to the nearest oculist to check my eye. He didn't check the intraocular pressure, but just take an ocular picture, show me my eye is swollen(i've known that), and give me two eyedrops, one is for inflammation the other is for allergy, and told me to observe if it will become better

interview of 由 田

i went the interview of 由 田 in chunha, 10 min ride from my home
different from 和 椿 that i had interview last Fri, the decoration is nice, wooden floor, a real lobby(the 和 has no lobby, when we go interview, we have to wait outside for a long time) although it's not the most important thing, but it did bias my opinion of that company.
the hr answer the call(actually there's no one stay at the lobby, u should use the phone at the door to call th ext.), took me into a room which is well decorated too, it looks like a meeting room, has a capacity about 50 people and a project screen. There was another person, doing some paper work. the hr make me to have a seat, and gave me an exam. The exam have three parts, logic, programing, English(reading and writing). The logic part took some time, but not so difficult. The programming part is most difficult for me, i was asked to write some eazy and short program in C++ and  answer some definition quesion of some thing like different between *(pointer) and &(reference), inline function, overload, i know some, but not very sure, worst of all, i haven't really write C++ program, it's hard for me to write the program on paper without reference ( finally i just get 51, if my glimpse is right ) the English reading is eazy, but i had no confidence in the writing test of writing a mail to asking for some help to the supplier's engineer.
when i was writting, the other man finished his test, hr collected it and read. Minuts later, hr came back and told him that he didn't do well on the programing test, he not going to take the following interview... this make me nervous
i was passed! actually, i'm not sure about it, hr didn't told me the grade, but he gave me some document to sign(i've almost forgot the content, but there somthing the overtime pay, and it says RD have no overtime pay...) and it's usual for them to work until 7 or 8 pm (the "normal off time is 5:30"..), the hr keep emphesize that was common in their industry...(i believe it, but i don't want to take it)
then i have interviewed by an engineer, then his boss(it's quite intresting that the boss refuse to tell who he is), they asked me some basic quesion of image processing, like how to detect moving objects, how to detect defect, it's not too difficult, and ask somthing about my thesis ( but actually i didn't remember much). when they ask if i have any quesion, i think i didn't prepare well about this, i don't konw what do i want to know, i didn't ask the pay, the welfare, i did ask about the job, but it's hard to ask deep quesion. the interview end by the introduction of the whole company and the advertisement of their new business unit, but the AOI still earn 90% profit (oh, they said they've got alot order and is going to earn more this year)!

the culture shape our desire

if the desire is shaped by our culture, and the criticism is adviced by the same. Isn't it contradict to convict people of desire? culture makes us aspire after money, power, sex... but all of these are evil... how could this happen? can i just finding love, happyness, peace for whole day? they will say i'm a lazy man, and threaten that i'll not able to feed myself up

the culture shape our desire

what should i do now?

as a firing (dying) man, what should i do during my office time?
it's intresting, just like what should a dying man do during his living time. The worse thing is i'm just a rookie now, i can do nothing than studying. but i still want to learn somthing from my first job, but it seems to be not possible.
or, should i just going on facebook, writing the blogger for months (it should be 3 month left), what is meanful? the section manager told us to pretent that we no nothing about leaving before everything is clear (before we are sure to be fired) but few days before, we signed the agreement if leaving (because we are研發替代役, it's not so eazy for us to leave) i'm not able to pretent nothing happened anymore.
manbe i should read some good books, maybe i should try to understand the code i got, maybe i should try my best to take some interviews (hope i can get some experience from them). leaving is a common end, but it comes too fast ( it usually comes too fast)

what should i do now?

find a job

today i went two interview, actually is one
i went 和 椿 which is found by my collage
it's at 桃園 蘆竹, under the Taiwan High Speed Rail Corporation
it's a company produce kinds manufactoring mechine
although it's in suburban area, there's no parking area in the company and no lobby
when i was there i find the parking place outside myself, take a small walk there, ring the bell folloeing the small instruction attacched near the bell, waiting for minuts. it's very different from my imagination, it seems that they're not care about it
i was there a little early(it could be earlier if i haven't take the road 65, which jam badly at the connection of highway 1), someone lead me to a seat (someother's seat, not some private roomXD), without any self introduction... hey, do every engineer not introduce themself when they  met other people first time? the office their is different from 宏 賴, they works in block, the desk is not separated, it seems they will distribute others when working, i've heard that japanese company always work like this
the minister isn't there, the vice-minister of development department as well as the minister of costermer service interview me, he don't see people in their eye, just reading my document. we have the interview in a room, not a meeting room but it seems a room for their leader, and we just take a seat at a table in a room. i've forgetten what his question is, just remember one of his children study chemistry in Tsinghua university, but he didn't tell a lot about him, maybe they are not in a good relationship XD~. Some minuts later, a younger person joined us, he's an engineer, about 33 years old, graduated from 中山 university, he started his work here since he graduated from graduate school (國防役), here seems to be good for him, he has joined a lot of project and keep coding.

Serialization

把物件(object)轉換成stream,以便儲存物件或將物件傳送到記憶體,資料庫或檔案當中,以便日後可以回復object的狀態。

雖然object可以透過初始化設定成預設狀態,but使用者在runtime所造成object的改變則需要透過Serialization來記錄。

依stream編碼方式的不同,Serialization可以分成binary與XML兩種,一般的window應用程式用binary儲存即可,且效率較好,但web應用程式則多用XML格式

炒魷魚

上禮拜處長把我們三個研替的叫進去會議室
跟我們說"你們也知道公司最近的財務問題吧?"
沒錯,的確有耳聞,秘書2月底被裁掉了,聽說很多部門都裁了很多人(不過也許因為我們部門還有在幫公司賺錢,或是目前有很多計畫在run,突然停下來要付很多違約金,要先把計畫都終結掉,總之我們部門我們幾個研替的應該是第一梯被裁)

不過處長說是週轉問題,似乎在蓋的廠貸款的資金不知道要從哪裡生出來吧?總之現階段是需要錢就對了

我們三個好像也沒有選擇的餘地,只能乖乖接受等待釋出被核准,再有兩個月時間找工作(不過有點可惜,沒能在公司多學到一點東西就要走路了)

雖然在跟處長談的時候很冷靜,但是有時候不滿的情緒還是會油然而生,雖然理性上覺得既然公司都在虧損了,這地方似乎也沒啥好留念的,但吃虧與不甘心的情緒好像不會因此就完全被壓制住(不過多多少少有點壓制效果)

在得知消息後就開始到處找人talk(不過不知道這是不是對的,隔壁課課長說,做一天和尚撞一天鐘,這種想法也許才是對我們最好的,畢竟我們還是得出現在這裡,也不是說知道會被釋出就可以拍拍屁股走人的,當和尚就是要撞鐘才能得到神明的保佑吧XD)搞得現在自己覺得公司的其他同事都知道我們要走人了,應該也不大會給我們事情做吧,光想到要在這邊空耗三個月就覺得有點哀傷(但往另一個方面想是支薪沒事幹的爽缺,除了有浪費生命的大帽子以外,可以做自己想做的事情又暫時衣食無虞不是蠻好@@?)

關於未來的出路,因為研替這個製毒時在風險太大,憑著短短幾個小時(也許是幾分鐘)的判斷賭上之後三年(這次如果被釋出是剩兩年半)的時光,偏偏年少菜鳥如我實在是很難有很好的理由相信自己可以做出如此正確有眼光的判斷。

掃除蜘蛛網

話說9月畢業到現在過了半年了,半年之間發生了很多事(?)
畢業完改了一陣子論文(沒多久)接著幫老爸(有幫到嗎?)送貨了一個月
接著在莫名其妙的trigger之下跑到歐洲(英,法,荷,法,瑞士,德國)去晃了一個月
回來之後馬上被抓去成功嶺又關了一個月
到最近的被關在公司過著比大學研究所還學生的有給的學生生活
看看上一篇文章的發文日期...20120426快要一年前 一年的空白 中間到底發繩了甚麼事?
這些日子總是把周遭發生的大大小小事情往fb上 然後一陣喧囂(或是被淹沒在茫茫fb海中)後船過水無痕
該是時候掃掃這滿是蜘蛛網的地方(不過也許同時也該掃掃我的房間)了

HDR2

話說昨天寫了一天的HDR作業
先是從數張快門速度不同的照片重建HDR
再來是將HDR壓縮回LDR

建立HDR影像


雖然現在論文的作者很負責任地提供了Matlab的Code可以下載,但不知怎麼在HDR重建時會遇到矩陣尺寸過大的問題,因此後來用Matlab內建的makehdr來重建


makehdr


在makehdr中需要設定線性區域的上下界與每張影像的曝光程度(快門速度) ,在有效範圍內的亮度值除以進光量(快門速度),得到真實亮度。將每張影像的真實亮度加入hdrTemp影像中,最後將hdrTemp中的值除以每個pixel有效的影像數(該pixel曝光程度在有效範圍內的影像總數)得到hdr影像
全部都過曝得像素填入最大值,全部都曝光不足處填入最小值,不是過曝就是曝光不足的部分利用旁邊的像素填滿~


HDR->LDR


compress low frequency part


將hdr影像mapping到LDR的部分,老師提供的code的概念是將影像中的細節與非細節部分分開,並對非細節部分進行較大的壓縮,再將此兩部分合成。而這兩篇論文的重點都在如何產生非細節影像。最理想狀況是將每個物體的明暗與紋理分開。


tone mapping


至於matlab內建的tonemap則是將影像取log2後並壓縮到[0,1]後轉到Lab空間,對L進行壓縮。壓縮L用的是constrast limited histogram equalization的方法,將影像分割成許多小塊(ex: 8x8)在每個小塊中做histogram eq. 使 histogram符合某種分布(ex:平均分布),在對附近的方塊使用內插法,以避免方塊之間的邊界太明顯。之後在將壓縮後Lab轉回rgb

姿勢跑法

昨天? 俠聖找到了隱居的紅框嘉!~
復團之後立刻分享了姿勢跑法的相關影片姿勢跑法的訓練跑法校正

看完後稍微摘要一下,摘要如下

姿勢跑法的訓練
1.前腳掌著地
2.可以脫鞋試試看
3.習慣前腳掌著地後,穿薄鞋子跑
4.把跑鞋穿回去
5.加速!!~
ps要先鍛鍊小腿與腿的力量才能使用此跑法XD

跑法校正
前半段影片是改造前
此人問題在腳落地太前面,身體太向前傾,屁股太懶惰XD,起伏很大
可以從後半段看就好(2'11"),改造後
腳的著地點要靠近質心,不要伸得太前面,否則會得到反向推進力~
屁股,肩膀,腳要在一直線上,以得到更好的減振效果
屁股不要起起伏伏
每分鐘腳要著地至少180次(spm,foot strikes per minute)以便利用韌帶等軟組織儲存的能量,同時減少花在支撐身體的時間
不要想利用往後推地板的反作用力推金身體,而是不斷的把腳拉回前面(有點像騎腳踏車XD),速度快時"勾腳"的程度會加強
腳步要輕,不要加快節奏而加速腳落地的速度,讓腳自然落下
鍛鍊核心,屁股,下肢(lower leg),腳掌(foot)的強度,可以跑得更遠!~

some goods

話說今天228連假,做了超便捷阿羅哈客運跑回家
回家還是職業病,道處找程式用@@~
先是找了方便的批次縮圖軟體EasyImageModifier還蠻簡單方便用的
之前用photoCap有點功能太多太複雜
同一家公司還有出螢幕擷取程式Screenshoter可以每次都結取相同的銀幕範圍,在做投影片時還蠻方便的
最後竟然找到一個在DevC++上裝OpenCV的教學(雖然這件事似乎非常eazy)等回新竹來試試
