2.学会使用时间碎片和“死时间”。如果你做了上面的时间统计,你一定发现每天有很多时间流失掉了,例如等车、排队、走路、搭车等,可以用来背单 字、打电话、温习功课等。大家喜欢用MP3播放器听音乐,但是为什么不把一些学习的内容(英语会话、生字和录下来的广播新闻等)放入你的MP3播放器呢? 在国外,现在流行podcast,就是把一些可以用听来了解的信息,录入MP3播放器,在开车回家时听。我前一阵和同事一起出差,他们都很惊讶为什么我和 他们整天在一起,但是我的电子邮件都可以及时回答?后来,他们发现,当他们在飞机上和汽车上聊天、读杂志和发呆的时候,我就把电子邮件全回了。重点是,无 论自己忙还是不忙,你要把那些可以利用时间碎片做的事先准备好,到你有空闲的时候有计划地拿出来做。

Android sync problem___ Sync is currently experiencing problems. it will be back shortly
Had a search around and found a solution that worked for me (p.s. posted by someone else in another forum)
Go to "Settings". Select "Applications".
Select "Manage Applications".
Scroll down to "Contacts Storage"
Click on "Clear Data"
Go back to to "Settings" again and in "Data Synchronization"
resync by pressing "Synchronize Now"
Good Luck

c++ int operation 整数变换
c++整数变换是把小数部分去掉,而不是四舍五入。
double b=3.4
int a=int(b);
输出
a=3;
int a=int(b);
输出
a=3;
- Example 1,
double b=3.4
int a=int(b);
输出
a=3;
- Example 2,
int a=int(b);
输出
a=3;
