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"!

When you buy a new server, please do not just consider their price tag. Please also take Warranty Cost and what kinds of support the hardware provider can support. For the server, you won't use it just for a year. You must need to extend the warranty. Moreover, the server need to be always on, we need to consider the support, whether they can come on-site as soon as possible. Actually, those terms are more important than purchase price of server.

A few days ago, I found a device calls "Leap Motion" which is a 3D motion and gestures controls. That is a kind of "3D" Mouse. For example, you can move your hand in the middle air to control a block in the screen left and right, up and down. That is very similar what Tom Cruise did in Minority Report. I listened a lot of report from some online gadget shows about this.
Now, you can find it in a local disk smith store for $129.98, but that is a quite expensive. $129.98 for doing some 3D gestures to my computer is a bit too much for me.

There is one advantage of aglie, we can get the clients to test the system when the parts built during the sprint, rather waiting the testing stage. If the bugs can be found as near as the time of its creation, that would be the best. The developer should be the best memory about the buggy parts. That is better to wait for the testing stage. Maybe a month, we need to understand the bug report and "search" our memory, how those parts works, how come the bug is created. That is not good!
Thus, getting bugs fixed should be carried as easily as possible!
