Advanced SE-10 tool

1.Rainbow Filter

• Purpose: Due to the trend of the homosexual issues, Facebook launched a rainbow filter to celebrate that same-sex marriage is a legal. Though Facebook has a rainbow filter, I want to built a rainbow filter on my own. Furthermore, I also built a grayscale filer.

3.Batch grayscale photo

• Purpose:After the trip to Japan in last summer, I want to batch converting my selected photos grayscale images. There are 50 photos in folder images and I want to finish the action one time.

• programming language:java

• code:src/3-Batch Grayscale

• Development Environment:BlueJ
• note:

  • The program runs 210 seconds for converting 50 photos to grayscale

  • The performance is lower than my expectation and there are many space to improve.

4.Parsing Export Data:

• Purpose: Some studies show that the value of Taiwan's export items has decreased over years and I want to realize more information about exporting data. As a result, I write the simple program to parse the data in CSV file including 219 countries.

• programming language:java

• code:src/4-exports

• Development Environment:BlueJ
• note:I list several questions to realize more information related to Taiwan.

  • What are the export items of Taiwan?

  • Which countries export Wireless Communication Equipment? / South Korea

  • Which countries export semiconductors? / 5 countries

  • What are the export items of Japan, South Korea and Malaysia?

  • How many countries export semiconductors?

5.Parsing Weather Data:

• Purpose:We are used to receive weather reports from TVs or Apps. But I want to configure some constraints to parsing weather data to get some specific information. As a result,

• programming language:java

• code:src/5-weather data

• Development Environment:BlueJ
• Note:I want to find average temperature with the humidity more than 90 at 2012-07-31.

It shows that

Average temperature when high Humidity is 71.92500000000001

6.Analyzing Baby Names

• Purpose:In the Advanced Software Engineering course, I remember that Professor Jiau mentioned about the importance of English name. As a result, I find some name and did some investigation about ranking information from 134-year baby name data in the United State.

• programming language:java

• code:src/6-analyzing baby names

• Development Environment:BlueJ
• Note:Building my own filter was more interesting than my original expectation.

7.Find Unique IP Address

• Purpose:I want to find the unique IP addresses from the mass web logs.

• programming language:java

• code:src/7-Unique IP Adress

• Development Environment:BlueJ
• Note:

8.Counting Website Visits

• Purpose:I want to use the data structure of HashMap to store IP addresses in different days.

• programming language:java

• code:src/8-Website Visit

• Development Environment:BlueJ

9.Convert Gitbook to PDF

• Purpose:As I always write note on the Gitbook, which is a e-book writing solution.

  I want to save more time to convert my notes to pdf format. As a result, I download some library.

• Node.js

• NPM (Node Package Manager)

• calibre

• Note:Though this tool was not built on my own, installing process still cost me 5 hours due to wrong path installation.

10.Weather searching

• Purpose:I want to build my own weather searching engine, as a result, I deploy a very simple website to show the temperature of China's cities.

• programming language:Python

• Note:This web has the database problem when I click "history" to skim the searched histories.
