I got an email from Microsoft about new SQL Server version ,"Denali" CTP3, is released. I read their documents it got more support features in cloud. Moreover, its express version is more focus on localDB. This sounds like a in-process DB. That is very similar with sqlite. I have a look on that to how much improvements they have.

I had built a new application using System.Data.Sqlite. When I run the application, I got an exception, System.BadImageFormatException.Well, I found I was using 64-bit version, because System.Data.Sqlite will call some unmanaged dlls. So, it still needs to be in 32-bit. After I changed to use 32-bit dll,then all goods. Or you can switch your build target to 64 bit and using 64 bit dlls.

I have upgraded my Skype in android this week. I found there is a big improvement. The uer interface is much much nicer. Finally, it got a home screen, rather than a simple contact list style window. Moreover, now, I can send sms in there too! That is so great!

I wish to an android application. Although that is a small personal project, it still requires some server operations. Thus, I need to find a web host. I already have a web host in PHP. That is possible to write some php scripts for the communications with my android application. But Programming in PHP is not very fun. Then my next option is C#. I am a C# programmer for a few years. Writing some server logic in C# is a easy task for me. Moreover, C# is a good programming language. .Net Environment needs a lot of resource. I think that needs a VPS with 2GB of RAM to install .net and MS SQL server. That kind of VPS needs around $40 or more per month. Then Java seems to be my best option. a Glassfish and MySQL only needs 1GB RAM VPS. I can find some VPS with that kind of configurations under $30 per month. Java is a good programming language too. This option is the most feasible.

I had a quick look of Google Plus. I found that is a mixture of Facebook and Google Wave. You can put your contacts into different circles.You can get the friends' update from the circle. That is very similar in Facebook, you can put friends into the group. Another main feature of Google Plus is chatting. You can form a circle (group) to chat. That sounds like Google Weave. Just now, they don't call it weave, calls it circle!

Those features are interesting, I may try it out in the future.
