Paypal is my preference for online gateway. A number of people asked me why do I directly use the payment from a local bank. The customers can put the credit card details directly into my website and the transaction fee can be lower than paypal. There are a number of good reasons to use paypal. Firstly, Paypal has a large number of user base. There are a large of people just need to enter paypal user name and password to process the payment. They do not need to any credit card details and address at all. That is very easy friendly. Secondly, it supports a various payment method across world. The most useful method is bank transfer. Paypal can do the bank transfer in the most of countries. For example, I am selling software in Australia, my customer in Hong Kong can transfer the money to me from their bank account. Thirdly, that is about the trust. Paypal won't give us any customers' details rather than email address. The customers won't be worry about the sellers to misuse their personal information. Lastly, Paypal is widely using. A number of third party can be available. We do not need to do any custom development. For us, Paypal is the best option!

Recently, there are a number of friends to ask me how to Speed up their old computer. They are willing to pay a small amount of money to upgrade their hardware.
1. I will find some more RAM, at least, upgrade to 4GB, Ideally, 8GB is the best
2. If they are willing to pay, I will upgrade their OS hard disk in SSD,

If they are not possible, I will just ask install "Linux"!

I tried to build another logic flow in story board after the add button clicked.

This is easy. Please add them in the main view controller.

Code

Moreover, you need to fill in 'AddTipReccordView' in StoryBoardID.
However, at first, I used the storyBoardID as 'AddTipReccordViewController' . I got this error:
' Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Storyboard
(

) doesn't contain a view controller with identifier 'AddTipReccordViewController'''

That is because I have "Controller" in StoryBoardID. That note, I have a controller as AddTipReccordViewController.h and AddTipReccordViewController.m. After I removed "Controller", I found StoryBoardID cannot be same as the controller I have in the project.

I built an Ubuntu Kylin 13.10 laptop. That is because my friend's laptop got a virus, and it need to be re-build. I am not able to find a recovery disk and I aimed to find a way to fix that laptop without any charges. Thus, I got a linux reflash on the laptop. At first, I got a KUbuntu, because it has KDE which is very similar with Windows. But I cannot get the Chinese input method working in OS. So, I installed Ubuntu. That works very fine, all hardware drivers missing and Chinese input method is working fine too. Personally, I like that UI more. That is a side bar for all frequent use programs! I wish my friend like it!

My friend brought a ThinkPad SL500 to me. The login password are changed by somethings, that sounds some virus in there. I decided to rebuild the machine. So, I pressed F11 during the startup to enter the recovery center. Then I choose the option to recover the machine with factory setting, I got the message "Not found c:\preload\convert.cmd ". I phoned their helpdesk, I have been told that is because of recovery partition are missing. Thus, the only way to grab a recovery disk from Lenovo.
