Most satellite dish actuators send a series of pulses to indicate their position. By Counting pulses the positioner knows where the dish is pointing. It is possible to use a serial port and Linux with RTAI patches in order to Count these pulses, thus minimising the external hardware required for a positioner. The zip contains instructions, circuit diagrams and example code.

Collection of key-value pairs. TDictionary represents a generic collection of key-value pairs. This class provides a mapping from a collection of keys to a collection of values. When you create a TDictionary object, you can specify various combinations of initial capacity, equality operation, and initial content. You can add a key that is associated with a corresponding value with the Add or AddOrSetValue methods. You can remove entries with Remove or Clear, which removes all key-value pairs. Adding or removing a key-value pair and looking up a key are efficient, close to O(1), because keys are hashed. A key must not be nil (though a value may be nil) and there must be an equality comparison operation for keys. You can test for the presence or keys and values with the TryGetValue, ContainsKey and ContainsValue methods. The Items property lists all Count dictionary entries. You can also set and get values by indexing the Items property. Setting the value this way overwrites any existing value. The class TObjectDictionary inherits from TDictionary and provides an automatic mechanism for freeing objects removed from dictionary entries.

最近在學(xué)習(xí)Oracle，對(duì)測試人員而言必須掌握兩種語言：第一種是DML，數(shù)據(jù)操縱語言 (Data Manipulation Language) 是SQL語言中，負(fù)責(zé)對(duì)數(shù)據(jù)庫對(duì)象運(yùn)行數(shù)據(jù)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(shù)據(jù)查詢語言 (Data Query Language) 是SQL語言中，負(fù)責(zé)進(jìn)行數(shù)據(jù)查詢而不會(huì)對(duì)數(shù)據(jù)本身進(jìn)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，F(xiàn)ROM：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(shù)時(shí)用到，如SUM,Count,MAX,AVG；HAVING：對(duì)聚合結(jié)果進(jìn)行篩選，這是和WHERE的不同點(diǎn)；ORDER BY：排序。
