Lab Testing User Interface
kFor housing services, compare the three websites
http://www.urmap.com.tw/asp/kijiji/
List the differences in the user interface design and usability. Make commentsby your use experiences.
美感，直覺性，流暢，預期反應
美感: houseing map就只是單純的一張地圖沒啥美感，urmap一堆文字美感很差，7house藉著許多廣告增添許多色彩。直覺性:houseing map一看就知道再找房子的，7house廣告有點多，看了一下才知道用途，urmap一開始以為只是找路的地圖。
流暢: 無庸置疑一定是housing對流暢，另外7house還可以一次訂下所有條件也算是個優點，urmap一點都不流暢，難使用。
預期反應: housing比較適合租屋者，條件比較寬鬆，最主要是價格跟地點。7house比較適合購屋者，條件比較多。Urmap很難使用。

Lab Google Mars (AJAX)
1. Observe how Google Mars loads the map and does the zooming. Is the data downloaded oncefor all or retrieved on demand?
ans: retrieved on demand
2. HTML alone cannot perform the functions of Google Mars. So find out which code in the HTMLsource does the map things.
Hints: You may use Nvu to determine what HTML tags are for what.

2. Click GetPlacesInside and play with this operation
3. Enter 61801 as zip code and see what you get in the result.
4. Try again 92345 as zip codeQuestion:
Why do you need a license key to use the service?
Homework 6-7-2008
Content analysis做完之後，請針對分析數字結果，給予適當詮釋，背後的現象是什麼? (至少100字)
ans: Total:118
C : 16 (13.559%)
R : 94 (79.661%)
U : 8 (6.780%)
A : 67 (56.780%)
D : 14 (11.864%)
M : 37 (31.356%)
E : 37 (31.356%)
P : 79 (66.949%)
N : 2 (1.695%)
由上述分析來看.最多的回應以"RAP"為主.代表回應屬於有思考過並給予正向回應的.而"UDN"是最少比例的.推文以有思考過但卻持反面意見並帶有強烈措辭甚至情緒話的字眼為主所以可以知道大部分的人對作者都會持正面積極的態度.少部分會消極且情緒化.

Lab SSL
1. Try Yam membership enrollmentfor using SSL encrypted Internet communications.
2. Note the lock at the lower right corner is secured when SSL is enabled.
3. Click the lock icon and a message window should pop up.
4. What kind of encryption is used in this SSL? How many bits are there in the encryption key?
ans : MIS 1285. Who issued the certificate you are seeing? (Who is the certificate authority, CA, for this website?)
ans : UTN-USERFirst-Hardware6. Until when is the certificate valid?
ans : 時效3年7. What kind(s) of hash is/are used in the CA's digital signature?
ans : SHA1 , MD58. How many bits are there in the hash(es)?
ans : 128Lab Hash
1. Install SlavaSoft HashCalc
2. Open the file readme.txt of this software
3. Calculate the cash.
4. Open another copy of HashCalc
5. Open the file readme.txt and delete the first space fo the file.
6. Calculate the hash of the modified file.
7. Compare the hashes of two files
Lab Checking dead links
W3C Link Check 可以檢查 dead links, 而且只要輸入首頁,就可以依據指定深度自動向下檢查, 而且也可以檢查對外連結(外站).Link Checker 首先要設定檢查深度(Check linked documents recursively, recursion depth=?), 如果沒有設定, 它就只有檢查首頁.因此如果出現 deadlink, 就是在首頁.如果你設定檢查深度, 它就會逐一檢查此深度內的每一頁,在檢查某一頁開始時, 它會先顯示現正在檢查的 URL, 然後在逐一爬行該頁內每個 link.報表輸出很漂亮. 請參閱http://validator.w3.org/checklink請檢查三個你最常使用的網站, 看看連結的品質如何?紀錄有錯誤連結 (HTTP Error 404) 的次數.

Lab Magic Parking Tower
A parking tower is out of order someday. If you park a Benz, you will end up with a Torben. Write a program to simulate this scenario. First create a class called CarParked which has a static method called outOfOrder. Name an object called yourCar, which happens to be a Benz. Your program should contain a class called CarParked and a test program called CarParkedDemo which test the method by CarParked.outOfOrder(yourCar).
Hint: You may study Display 5.14 to get some ideas.
Lab Static method
Define a Complex class with a static method for computing complex addition. Use (2+3i)+(4+5i) in your test.
lab Fraction equality test
Write a program to implement a method that can check whether 2 fractions are equal. You will implement a class called Fraction consisting of a numerator and a denominator. The equality test of 2 fractions should return a boolean value.
Use the following as the tests.

5/6, 6/7
5/6, 6/7
Hints:
Fraction f1, f2;
f1.equals(f2);
lab Fraction Addition
Write a program to implement a method that can do additions of 2 fractions. You will implement a class called Fraction consisting of a numerator and a denominator. The additions of2 fractions should be equal to a fraction.Use 1/2+1/3 as the test.
