最近在學習Oracle,對測試人員而言必須掌握兩種語言:第一種是DML,數據操縱語言 (Data Manipulation Language) 是SQL語言中,負責對數據庫對象運行數據訪問工作的指令集,以INSERT、UPDATE、DELETE三種指令為核心,分別代表插入、更新與刪除。第二種是:DQL,數據查詢語言 (Data Query Language) 是SQL語言中,負責進行數據查詢而不會對數據本身進行修改的語句,這是最基本的SQL語句。核心指令為SELECT,以及一些輔助指令,如FROM、WHERE等,FROM:表示來源,可以搭配JOIN做鏈接查詢; WHERE:過濾條件;GROUP BY:在使用聚合函數時用到,如SUM,COUNT,MAX,AVG;HAVING:對聚合結果進行篩選,這是和WHERE的不同點;ORDER BY:排序。

Arduino 是一塊基于開放原始代碼的Simple i/o 平臺,并且具有使用類似java,C 語言的開發環境。讓您可以快速 使用Arduino 語言與Flash 或Processing…等軟件,作出互動作品。Arduino 可以使用開發完成的電子元件例如Switch 或Sensors 或其他控制器、LED、步進電機或其他輸出裝置。Arduino 也可以獨立運作成為一個可以跟軟件溝通的平臺,例如說:flash processing Max/MSP VVVV 或其他互動軟件… Arduino 開發IDE界面基于開放原始碼原則,可以讓您免費下載使用開發出更多令人驚奇的互動作品。 什么是Roboduino? DFRduino 與Arduino 完全兼容,只是在原來的基礎上作了些改進。

RC4對文件加解密 實現RC4對任意文件的加解密,利用控制臺對所有文件(中英文文本、符號甚至任意的文件)的加解密。 加解密形式如下: RC4 -e/-d key inputfile outputfile 說明:對于加密來說,輸入文件名就是明文文件,對于解密來說,輸入文件名就是密文文件,注意文件讀取方式和控制文件結束。 控制臺編程: int main(int argc, char *argv[ ])
