A lot of people prefer to build a web app. They think using ASP.Net MVC or PHP + jQuery will be the best option. jQuery can make a web interface as good as a windows UI. Nowadays, web page can do a lot of interactions. Moreover, the users only need a web browser to access the application, no installation of software are required. However, our Company, AdvGen, still has some projects in WPF or Winforms, such as AdvGen Contact Manager and Adv Timer Assistant. That is because jQuery UI is very hard to test and so easy to have bugs. Moreover, WPF and Winform are still able to provide more interactions and easy to build. Thus, we still love WPF and Winforms!

Recently, I traveled to Seoul from Hong Kong. I rented a mobile modem from Vison Data. That costed HKD$60 per day and HKD$1000 as the deposit. This is quite reasonable. Moreover, the process is convenient. I booked the modem online, and then you can pay the rent fee and deposit into their bank account or pay the money in their office. Finally, I picked the modem from their office the day before our trip. Of course you can pay $20 for express post. Then the modem will be delivered to your home.

For speed, that is our reasonable too. 0.97 Mbps for download and 0.43 Mbps for upload.

Lastly, I wish to talk the return process. That is simple, you need to pick back the modem to their office before the second day of your return. Of course you can pay $20 for express post too. Then they will give your a cash cheque to you.

During recent Years,"Social Media" is a popular term in the marketing world. A number of people have asked me what is "Social Media Marketing". Social Media is a good tool for marketing. It helps to spread out your name from your friends to their friends, then from their friends' to their friends' friends etc.
You need other good tools. You still need a website. There is a limited information in social media. You need a website to put the detailed information. Moreover, a number of people are still using search engine. You still need a website for search engines to do indexing. Lastly, you need a website to build your corporate image! Please do not forget the old good tool!

Recently, there are so many people asked me, "can you build an apps for me?" First of all, I wish to ask what is the purpose to your own app. Well, the most popular answer is "I wish the mobile users can access the information in my website!". So, I will recommend them to build a responsive website.
To build a responsive website is only adding a mobile css and maybe jquery tricks into your existing website. That is much lower cost. Moreover, the user is more prefer to enter url rather than installing an app.
Nowadays, mobile apps sounds a cool stuff which everyone wish to have, but we need to ask whether you really need that. There are plenty of choices out there!

Building a data layer in sqlite for android is a bit of time consuming. Recently, we have moved to the IOS world. I found that is a bit easier to build in data layer in there. It has Core data concept which is a kind of ORM. But that is completely OOP storage. Please do not think in sql way. I tried to find auto number key and foreign key in Core data. There is no such things ,please think in objects and relationship. That works and is easy too!
