Clear location service object in resign active

Since iOS 4.0, I am aware freeing unnecessary object when the application is in inactive state so that the app can free up as much memory as possible. So in one of me location based app, I try to free the location service object when it is inactive:

- (void)applicationWillResignActive:(UIApplication *)application {
self.locationService = nil;

Charge your iPad using USB port on your PC

If you are PC user, you will feel frustrating that you cannot charge your iPad through the PC's USB. I've thought that it is the hardware limitation of PC, but I was wrong. After install this ASUS ai charger:


You can now charge your iPad using the USB port of your PC. The software even claim it will charge iPhone and Ipod Touch faster that I didn't test. The software is not limited to ASUS motherboard, I successfully installed and used on my Foxconn motherboard without any problem.

例如,如果尖沙咀去羅湖,原本八達通票價是 $34.8,但如果在粉嶺或上水先出閘再入閘,車資便是$11+$19.5=$30.5了,可以節省 $4.3!

DIY iPad/iPhone 筆

(Chinese only)

比起 iPhone,iPad 我大畫面真是很適合用來畫畫。但是用手指畫好像還是不大舒適,不如大家DIY一枝 iPad 和 iPhone 也可以用的 stylus 吧! 材料只需要:

1. 3M 清潔海綿。
2. 一枝筆桿。選擇筆桿是最難的,我認為有幾個要素:
- 筆桿最好是金屬的,其實 iPhone stylus 的原理是把身體的電容經過筆桿再經3M 海綿傳到 touch screen,如果筆桿不是金屬,你便要在筆桿繞上金屬線和手接觸。
- 筆頭的孔最少要有5MM,或可以改裝到5MM,以給海綿通過。
- 筆頭最好是膠的,因為海綿之後就是筆頭,如果是金屬的碰到 touch screen 便不太好。
3. 一條電線。

這是我買的海綿,注意一定要3M的,其他的不保證可以。3M 藍色和粉紅色的海綿也可以。我買有百潔布的是因為它比較平。
