以下是個人心得

Arm 版本不是使用setup_header結構,而是一個所謂ATAG 的結構佇列,bootloader需要自行在記憶體中建立一個ATAG佇列.這個佇列的的開始位址,在bootloader 開始執行kernel的start code 前,放在Arm CPU 的R2暫存器內.(R1暫存器放機器型別代號)

現實生活是,因為錢不夠,或是擔心風險,或是其他屌毛原因,一定會被限制最大口數(俗話就是滿倉啦).那麼會有幾種狀況產生

1)出手加碼的單位越小,加碼次數越多,每趟獲利會越低,但每趟的最大虧損也會有越低的趨向,勝率會有下滑的趨向.有時候盤整太久,虧損的趟數太多,最大連虧有是可能比(2)還多

2)出手加碼的單位越大,加碼次數越少,單趟獲利會越高,但單趟虧損也會非常高,除非是勝率很高,否則最大連虧會非常驚人
要怎麼選1 or 2 ? 加碼的單位與次數該怎麼調?就看口袋深度囉

股市,或是任何交易,可以化約為一個非線性動力系統(基於供需原理),既然是非線性動力系統,就跟混沌扯上關係.

將每筆成交的交易價格逐一記錄下來,就是這個非線性動力系統的相空間.這個相空間顯示了一個奇異吸子,一個碎形.所以股價圖(K線圖)就是一個碎形

不論你用任何時間尺度去觀看股價變化,都會看到股價圖大致上呈現類似的圖形,1分K的K線圖跟月K線圖長得樣子基本上很像,有上下震盪(趨勢)的時候,也有平靜(盤整)的時候,如果你願意,可以把平靜的區間再加以更細的時間尺度去看,仍然可以看到上下震盪與平靜交互顯現

既然已經做出"股價圖有碎形特性"的假設,那麼,依據此假設,任何追蹤形股價策略(均線策略,通道策略,追蹤形技術指標)再任何時間尺度下都是有效的,用在分K圖有效,用在周線圖自然也有效,用在月線圖也有效</summary><link rel='replies' type='application/atom+xml' href='http://leolarrel.blogspot.com/feeds/7708237892663516630/comments/default' title='張貼意見'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=7400013760219014524&amp;postID=7708237892663516630' title='0 個意見'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/7400013760219014524/posts/default/7708237892663516630'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/7400013760219014524/posts/default/7708237892663516630'/><link rel='alternate' type='text/html' href='http://leolarrel.blogspot.com/2011/05/blog-post.html' title='混沌,碎形,股價'/><author><name>leo</name><uri>http://www.blogger.com/profile/09374815177539632147</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-7400013760219014524.post-6681365331916922988</id><published>2011-03-13T13:25:00.002+08:00</published><updated>2011-03-13T13:26:21.457+08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='android'/><title type='text'>在非ubuntu的linux build android x86 source 可能會遇到以下問題</title><summary type='text'>各位看官:

可以用檔案分享來作一個比喻,會比較容易瞭解.檔案分享有中央控管的Server/Client(ex. ftp),跟點對點(ex. BT).S/C模式的檔案放置一固定位置,取用的人需要知道位置與取得權限,點對點則沒有固定的位置,也不需要取得權限.如果要同步本機磁碟裡的資料,相對於使用S/C模式來說,只有登入server一途.如果server 壞掉了將沒有辦法同步資料.點對點技術不需要知道資料的位置跟權限,只要點對點環境中有另一個節點也持有資料便可以.只要加入點對點網絡,大家都是server,大家也都是client. 對於版本控制系統來說,專案成員間的程式碼分享與合併所遇到的困難與檔案分享是一樣的.使用中央控管的版本控制系統,需要一個固定位置,專案的成員都需要配給”權限”.成員被限制只能與中央統一的一份程式碼作合併作業,分散式的版本控制系統,</summary><link rel='replies' type='application/atom+xml' href='http://leolarrel.blogspot.com/feeds/7729119507565504787/comments/default' title='張貼意見'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=7400013760219014524&amp;postID=7729119507565504787' title='0 個意見'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/7400013760219014524/posts/default/7729119507565504787'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/7400013760219014524/posts/default/7729119507565504787'/><link rel='alternate' type='text/html' href='http://leolarrel.blogspot.com/2010/11/vs.html' title='版本控制系統:中央控管 vs 分散式'/><author><name>leo</name><uri>http://www.blogger.com/profile/09374815177539632147</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-7400013760219014524.post-5862239842325452481</id><published>2010-08-29T12:51:00.003+08:00</published><updated>2010-08-29T12:55:28.664+08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='期貨'/><category scheme='http://www.blogger.com/atom/ns#' term='投機'/><title type='text'>[備忘]取得每日交易價格資料</title><summary type='text'>期貨交易所提供很多天的交易資料,當然都是以日為單位,沒有提供"分"為單位的就算當天需轉倉人卻不在電腦前,之後一樣可以抓到當然的資料塞入excel</summary><link rel='replies' type='application/atom+xml' href='http://leolarrel.blogspot.com/feeds/5862239842325452481/comments/default' title='張貼意見'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=7400013760219014524&amp;postID=5862239842325452481' title='0 個意見'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/7400013760219014524/posts/default/5862239842325452481'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/7400013760219014524/posts/default/5862239842325452481'/><link rel='alternate' type='text/html' href='http://leolarrel.blogspot.com/2010/08/blog-post.html' title='[備忘]取得每日交易價格資料'/><author><name>leo</name><uri>http://www.blogger.com/profile/09374815177539632147</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-7400013760219014524.post-4873894443341987289</id><published>2010-03-02T01:24:00.001+08:00</published><updated>2010-03-02T01:27:15.364+08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='期貨'/><category scheme='http://www.blogger.com/atom/ns#' term='投機'/><title type='text'>Kelly Formula 凱利公式</title><summary type='text'>Kelly Formula 是一個界定資金管理的科學模型,詳情可以  google 'Kelly Formula' ,這邊就不再浪費網路空間</summary><link rel='replies' type='application/atom+xml' href='http://leolarrel.blogspot.com/feeds/4873894443341987289/comments/default' title='張貼意見'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=7400013760219014524&amp;postID=4873894443341987289' title='0 個意見'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/7400013760219014524/posts/default/4873894443341987289'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/7400013760219014524/posts/default/4873894443341987289'/><link rel='alternate' type='text/html' href='http://leolarrel.blogspot.com/2010/03/kelly-formula.html' title='Kelly Formula 凱利公式'/><author><name>leo</name><uri>http://www.blogger.com/profile/09374815177539632147</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-7400013760219014524.post-9202398964711602051</id><published>2010-02-23T13:00:00.002+08:00</published><updated>2010-02-23T13:19:50.333+08:00</updated><title type='text'>騎乘技術 之 油門 part 3 (chapter 5 of A Twist of the wrist II)</title><summary type='text'>這一章開頭是 Get it onGet it on 意思就是"把油門打開"為什麼要打開油門?keith 則是先討論"關掉油門".關掉油門有以下反應o)荷重往前,前輪負擔增加,後輪荷重減少,抓地力減少o)避震器沒有處於完美的行程間,導致避震器做動過於敏感o)轉向變快了,有過動的傾向o)車有往外邊去的傾向,而不是穩穩的在路線上o)cornering ground clearance is reduce (轉彎的空地減少了?)o)車子變慢了那麼,開油門有啥好處? 可以先參閱以上兩篇油門的文章.什麼時候要開油門? 盡可能快 .

type='text'>*NIX programming : 系統提供的 HASH實作</title><summary type='text'>

Unix 系統內定提供一個簡單的HASH 表實作.依照POSIX.1-2001的規範,OS應該提供以下三個介面 :hcreate(), hsearch(), and hdestroy() .這三個其實是很久已前SVR4時代就有的東西.

各位如果不愛看我的說明,可以自行 man 取得外國人寫的文件.--------------------------------------------

首先來看這三個介面的原型定義

int hcreate(size_t nel);

ENTRY *hsearch(ENTRY item, ACTION action);

void hdestroy(void);

首先hcreate 是通知系統先配置好一個記憶體空間. hsearch 則是負責hash元素的加入與搜尋(別被函式名稱騙了),hdestroy就是把hcreate配置的空間釋放掉
