我有位小書友，經常和我交流有什麼好書值得一看，但她看書的速度驚人地快，我經常會覺得自己是龜，她是兔。
這個人，是我的太太。
A Gift to My Children: A Father’s Lessons For Life And Investing 是她最近最欣賞的作者 Jim Rogers 的作品之一， Jim Rogers 的書她已經
利用 Java 檢查檔案或目錄的大小 (Use Java to check size of a file or a directory)
import java.io.File
public static long filesize(File file){ long size = 0L; if (file.isFile()){ size = file.length(); } else if (file.isDirectory()){ File[] nFiles = file.listFiles(); for (File nFile : nFiles){ size += filesize(nFile); } } return size;}兩種人
其實過個世界只有兩種人。
一種人是你請他做一件事，他馬上就做，遇上他做不來的事，他馬上就會坦承他做不來，跟你一起商量如何解決。
另一種人是，你請他做一件事，他會有很多問題，點解要我做呀？點解要咁做呀？點解
自訂的 Java File 排序 (Sort the File class in Java)
import java.util.Comparator;import java.io.File;
public class FileComparator implements Comparator{ public static final int NAME = 1; public static final int SIZE = 2; public static final int TYPE = 3; public static final int MODIFY = 4; public static final char ASCENDING = 'A'; public static final char DESCENDING = 'D'; private int method; private char order; public FileComparator(){ this.setMethod(FileComparator.NAME); this.setOrder
The impact of single-disk slow writes on mirrors (and other RAID arrays)
We had a performance problem today that we fairly rapidly determinedcame from our mail spool filesystem somehow being too slow. This waspretty impressive, because our mail spool sits on a four-way mirror on our fileservers and we could easilysee that our IO rate on its fileserver wasn't particularly large, wellbelow what we knew things could manage.
(Using NFS with a single interface makes IO rate easy to measuredirectly, no matter how complex your IO system; just look at the networktraffic volume.)
東坡和兩種豁達
昨天翻看《全宋詞》，見到一首蘇東坡填的〈南歌子〉，從前應該讀過，但沒有特別深刻的印象，現在讀來，卻十分喜歡：
帶酒衝山雨，和衣睡晚睛。不知鐘鼓報天明。夢裏栩然蝴蝶、一身輕。
老去才都盡，歸來計未成。求田問
毛孩 (+資料更正）
中學時代，就讀女校，沒男生可看，一眾女孩子異常苦悶，唯有日日夜夜對其他女生評頭品足。
任何一個同學有肉眼可見的唇毛、手毛、或腳毛，大件事啦～「毛孩」、「猿人」或「長毛象」任選其一，從此成為她的花名。

利用 Java 複製與删除檔案及目錄 (Use Java to copy and delete a file or a directory)
import java.io.File;import java.io.IOException;import java.io.FileNotFoundException;import java.io.FileInputStream;import java.io.FileOutputStream;import java.util.Arrays;
public static void copy(File source, File destination) throws IOException, FileNotFoundException{ if (source. exists() && !source.equals(destination)){ if (source.isFile()){ FileInputStream fis = new FileInputStream(source); FileOutputStream fos = new FileOutputStream(Menu
![]()
