cross platform mobile development comparison
There's a detailed comparison of all these toolkits in this article here: Modern Cross Platform Development.
There are a number of other solutions around like
Rhodes,
Titanium,
PhoneGap,
JUCE,
MoSync,
Corona and
Moai.
Each of these use a bunch different languages, including HTML5/JS/CSS, Lua, Ruby, Python and C++. All except Corona are open source and free.

reset sa password sql 2008
How to recover SA password on Microsoft SQL Server 2008 R2
When you are using MS SQL Server in mixed mode, it is very important that you know your SA password.
There can be different reasons you lost the password
- Person who installed the SQL Server knows the password but has left the building.
- You did not write down the password in your password file
- Password file is lost
- …
Steps to recover the SA password
-
Start SQL Server Configuration Manager
-
Stop the SQL services
-
Edit the properties of the SQL Service
-
Change the startup parameters of the SQL service by adding a –m; in front of the existing parameters
- Start the SQL services. These are now running in Single User Mode.
- Start CMD on tthe SQL server
-
Start the SQLCMD command. Now you will see following screen
-
Now we create a new user. Enter following commands
- CREATE LOGIN recovery WITH PASSWORD = ‘TopSecret 1′ (Remember SQL server has default strong password policy
-
Go
- Now this user is created
-
Now we grant the user a SYSADMIN roles using the same SQLCMD window.
- sp_addsrvrolemember ‘recovery’, ‘sysadmin’
- go
- Stop the SQL service again
-
Change the SQL service properties back to the default settings
- Start the SQL service again and use the new created login (recovery in my example)
-
Go via the security panel to the properties and change the password of the SA account.
- Now write down the new SA password.
