目標
如前一篇實作的範例(使用cheerio 抓取蘋果日報的RSS資訊)
這裡接著要做的是讀取CNN的RSS資訊

目標
在node.js下使用cheerio以及request來讀取蘋果日報的RSS資訊
在http://www.appledaily.com.tw/rss這裡可以看到有提供的的即時新聞群組列表
而這次實作的目的就在於取得群組列表以及將指定列表中的資訊抓下來

簡介
開發應用時突然發現要準備網頁的多國語系支援，上網找一下資料發現多國語系可以做在前台，也就是網頁html+js的搭配組合完成語系呈現。
前端開發可參考此連結，我是沒多研究就是了

Install redis

wget http://download.redis.io/releases/redis-3.0.0.tar.gz

tar xvfz redis-3.0.0.tar.gz

cd redis-3.0.0

make

server and client are placed in src/redis-server and src/redis-cli respectively.

usbmount

讓USB flash插入直接mount

 sudo apt-get install usbmount

 

samba

提供檔案共用

 sudo apt-get install samba

 

 mkdir /home/pi/share

 chmod 777 /home/pi/share

 sudo vi /etc/samba/smb.conf

 

 [Share]

 comment = ShareFolder

 path = /home/pi/share

 browseable = Yes

 public = Yes

 guest ok = yes

 read only = no

 

node.js

 wget http://node-arm.herokuapp.com/node_latest_armhf.deb

 sudo dpkg -i node_latest_armhf.deb

 

概述


設定locale與能否瀏覽中文的網頁沒有直接的關係，即便把locale設置成 en_US.ISO-8859-1這樣一個標準的英文locale你照樣可以瀏覽中文的網頁，只要你的系統裏面有相應的字符集（這個都不一定需要）和合適的字體（如simsun），瀏覽器就可以把網頁翻譯成中文給你看。具體的過程是網絡把網頁傳送到你的機器上之後，瀏覽器會判斷相應的編碼的字符集，根據網頁採用的字符集，去字體庫裏面找合適的字體，然後由文字渲染工具把相應的文字在屏幕上顯示出來。
