[travel]121110 富陽生態公園 維護 關閉

之前在找房子就有看到這附近不遠處有登山步道，
今天看起天氣很好。
所以想去晒晒太陽，帶著水跟水果就想往那邊出發。




哈，
非常不妙的。

富陽生態公園 在維護～～～～ 而且是整個關閉 oh no



前前後後也看了不少人是要過來走走的，
還有家長們帶著小孩子過來。




期待整修後的環境

今天早上看到一張辦公室的圖，
想起來現在位置其實滿棒的。



忙碌完畢後，我最喜歡對著外面發呆了。

[mahout]mahout recommender step

一般而言再使用mahout recommender來說，都有幾個步驟。

 

1. 建立模型
2. 計算相似度
3. 找k-nearest neighbor 
4. build recommender engine



public static void main (String args[])throws Exception{
DataModel model =new FileDataModel(new File("data/intro.csv"));
UserSimilarity similarity =new PearsonCorrelationSimilarity(model);
UserNeighborhood neighborhood =new NearestNUserNeighborhood(2,similarity,model);
Recommender recommender= new GenericUserBasedRecommender(model,neighborhood,similarity);
List recommendations =recommender.recommend(1, 2);
for(RecommendedItem recommendation :recommendations){
System.out.println(recommendation);
}

}

[電影]陣頭

不得不說，原來他票房會這麼好不是沒有道理的。

除了傳統面對現代環境改變的掙扎，
親情，友情，還有社會的觀感。
每個人都很努力的做出取捨。

看到最後居然飆淚了。

把西螺真的拍的很美，
有好幾幕都是曾經在地方，
可是拍起來就是很不一樣。

[mahout]run apache mahout examples

run apache mahout examples

官方網站上面有個有個說明，

Recommender Documentation - Apache Mahout - Apache Software Foundation
https://cwiki.apache.org/confluence/display/MAHOUT/Recommender+Documentation

To build and run the demo, follow the instructions below, which are written for Unix-like operating systems:

1. Obtain a copy of the Mahout distribution, either from SVN or as a downloaded archive.
2. Download the "1 Million MovieLens Dataset" from Grouplens.org
3. Unpack the archive and copy movies.dat and ratings.dat to trunk/integration/src/main/resources/org/apache/mahout/cf/taste/example/grouplens under the Mahout distribution directory.
4. Navigate to the directory where you unpacked the Mahout distribution, and navigate to trunk.
5. Run mvn -DskipTests install, which builds and installs Mahout core to your local repository
6. cd integration
7. You may need to give Maven more memory: in a bash shell, export MAVEN_OPTS=-Xmx1024M
8. mvn jetty:run.
9. Get recommendations by accessing the web application in your browser: http://localhost:8080/mahout-integration/RecommenderServlet?userID=1 This will produce a simple preference-item ID list which could be consumed by a client application. Get more useful human-readable output with the debug parameter: http://localhost:8080/mahout-integration/RecommenderServlet?userID=1&debug=true

[Mac]bashrc not work

By default, Terminal starts the shell via /usr/bin/login, which makes the shell a login shell. On every platform (not just Mac OS X) bash does not use .bashrc for login shells (only /etc/profile and the first of .bash_profile, .bash_login, .profile that exists and is readable). This is why “put source ~/.bashrc in your .bash_profile” is standard advice. –

Zookeeper 與 Hbase 為什麼要用zookeeper

Hbase 使用zookeeper 管理 HMaster 與 RegionServer。
Hbase也就是從BigTable來的，當table大到一個程度的時候，table會split成一個一個的region。
而RegionServer就把 HTable 存到Hadoop的HDFS。
Google BigTable使用Chubby來負責協調Node的工作，而HBase使用的就是zookeeper。

Hadoop in Taiwan 2012

很幸運上工沒多久，
就可以去參加這個活動。

早上六點半就出門，
七點半到辦公室一起搬螢幕跟電腦過去會場。

一如往常的大型的資訊活動都轉往中央研究院辦，
今年早上的演講大部分是被趨勢給包場了。

當然，還有聽到Steve 的喊話，
什麼是台灣人的新的機會呢？
我想就是腦力阿。

整個議程算是一個拋磚引玉，
越來越多應用用新的模式來呈現，
難怪乎當時有問cutting說，hadoop到底造成怎樣的影響，
他回答，出現了hadoop讓大家用新的方式思考Big Data，
真的，在hadoop出現以前，這些問題就早已經存在了。
只是這樣的pattern被更廣佈的炒熱了。
