Step One.

Before installing anything please run the following command (actually 2 commands)

Install Java! You develop on android or not Java is a must on all my machines

You can now check your java installation by issuing two commands:

You should be able to see output stating that you have java 6 installed, huuraaayy!

Step Two.

Download and install Android SDK
You can download the latest android SDK from the android development website (developer.android.com), the link to the latest version is here
After your download completes, unzip the file to the directory of your choice. I copy the whole folder into my home directory but the doesn’t really matter.
Open up your favourite text editor (VIM of course) and add the following line at the very bottom of the .bashrc file:

Stepp Three

Download and Install Eclipse

I wish I could go for the easy one here and download the version using apt-get but unfortunately not as the version in repos is 3.2 and ADT plugin requires version 3.3 or higher. You have to download the eclipse for www.eclipse.org and unpack it. Once unpacked its ready to use!

Step Four

Download and install Eclipse plugin
This is instruction from the developer.android.com with one small modification, instead of https use http:

1. Start Eclipse, then select Help > Software Updates….
2. In the dialog that appears, click the Available Software tab.
3. Click Add Site…
4. Enter the Location:

http://dl-ssl.google.com/android/eclipse/

If you have trouble aqcuiring the plugin, try using “http” in the Location URL, instead of “https” (https is preferred for security reasons).

Click OK.
5. Back in the Available Software view, you should see the plugin listed by the URL, with “Developer Tools” nested within it. Select the checkbox next to Developer Tools and click Install…
6. On the subsequent Install window, “Android DDMS” and “Android Development Tools” should both be checked. Click Next.
7. Read and accept the license agreement, then click Finish.
8. Restart Eclipse.

After executing all the steps above you are ready for Android development. The last step in this tutorial is to run example android projects on your linux dev machine.
If you encounter an error saying :

An error occurred during provisioning.
Cannot connect to keystore.
JKS

Please check your java version. If its set to 1.5 than please run the following command:

Once you finish installing required plugins, restart your eclipse and go to Window->Preferences->Android and set up a path to your android SDK

Step Five

Check your configuration

If all went fine you can try to develop Hello World application in android. You can find the instruction on the android development site:
http://developer.android.com/guide/tutorials/hello-world.html

More android tutorials to come!
Enjoy!

Assuming we have some private fileds ready:

private Server sqlsrv; //initialized when connection succeedes

        private string dbName;

        private string backupFile;

        private string serverName;

        private string sqlUser;

        private string sqlPass;

Lets first create a connection to our database server and initialize our Server type object:

private bool connectToSQLServer()

        {

            try

            {

                ServerConnection serverConn = new ServerConnection(this.serverName);

                // Log in into sqlserver

                serverConn.LoginSecure = false;

                // Give the login username

                serverConn.Login = this.sqlUser;

                // Give the login password

                serverConn.Password = this.sqlPass;

                // create a new sql server object

                sqlsrv = new Server(serverConn);

            }

            catch (Exception ex)

            {

                Console.WriteLine(ex.StackTrace);

                return false;

            }

            return true;

        }

If all goes fine and we have our Server (sqlsrv) object ready we can start our backup operation:

public bool bakBackup()

        {

            //If the connection returns false return from this method too.

            if (!connectToSQLServer())

                return false;

            try

            {

                // Create a new backup object

                Backup bkpDatabase = new Backup();

                // Set the type to database

                bkpDatabase.Action = BackupActionType.Database;

                // set the database name we want to actually backup

                bkpDatabase.Database = dbName;

                // To get the file from me actual backup create BackupDeviceItem

                BackupDeviceItem bkpDevice = new BackupDeviceItem(this.backupFile, DeviceType.File);

                // add the backup file device to our backup

                bkpDatabase.Devices.Add(bkpDevice);

                // execute the actual backup using Smo

                bkpDatabase.SqlBackup(sqlsrv);

                //verify if the file exist

                if (File.Exists(this.backupFile))

                    return true;

                else

                    return false;

            }

            catch (Exception ex)

            {

                Console.WriteLine("Backup file couldn't be created" + ex.StackTrace);

                return false;

            }

        }

As a side note I would mention that the only two folders I have found on my system where I can actually perform the backup (store tha bak file) is “C:Program FilesMicrosoft SQL ServerMSSQL.3MSSQLBackup” or “C:Program FilesMicrosoft SQL ServerMSSQL.3MSSQLData” folders, this has something to do with permissions setup and I’ll will update this post once I find the solution. You can read my post on stackoverflow regarding this issue.

Assuming that all went ok, lets create a zip file which will compress our bak file to the size more than 2 times smaller than the original bak file.
For file comression I will use great C# library ‘SharpZipLib’ which you can find here.
Before using the snippet below you would have to add a reference to the library in your project.

public static void Zip(string sourceFile, string destinationFile, int BufferSize)

        {

            FileStream fileStreamIn = new FileStream(sourceFile, FileMode.Open, FileAccess.Read);

            FileStream fileStreamOut = new FileStream(destinationFile, FileMode.Create, FileAccess.Write);

            ZipOutputStream zipOutputStream = new ZipOutputStream(fileStreamOut);



            byte[] buffer = new byte[BufferSize];



            ZipEntry entry = new ZipEntry(Path.GetFileName(sourceFile));

            zipOutputStream.PutNextEntry(entry);



            int size;

            do

            {

                size = fileStreamIn.Read(buffer, 0, buffer.Length);

                zipOutputStream.Write(buffer, 0, size);

            } while (size > 0);



            zipOutputStream.Close();

            fileStreamOut.Close();

            fileStreamIn.Close();

        }

Looks pretty easy? Well, actually it is! As a source and destination file arguments provide full path to your file (.bak) as source and (.zip) as destination and you are done.
You can of course change one name to another using simple call:

string zipFileName = fileName.Replace(".bak", ".zip");

Happy coding!

1. remove any earlier backup dirs and create new empty one
2. create mysql dump for the applications you want to backup
3. create tar.gz of the entire home directory
4. create tar.gz of the apache director to preserve settings
5. create tar.gz of everything I’ve created earlier to place everything in a single file
6. ftp the file to a backup server

Lets start with the first task. Removing and creating dirs is pretty simple:

rm -Rf /root/temp_bckp

mkdir /root/temp_bckp

Creating mysql backup we can do the easiest using mysqldump utility. The command for this is:

mysqldump --user=your_db_user your_db_name > /root/temp_bckp/your_Db_name.sql --password=your_db_password

echo 'sql dump finished'

Once we got all dumps in place we can start compressing home and apache directories directory:

tar -zcvf /root/temp_bckp/home_bckp.tar.gz /home

echo 'tar of home finished'



tar -zcvf /root/temp_bckp/etcapache.tar.gz /etc/apache2/

echo 'tar of etc/apache finished'

Somwhere at the top of the script we store current date as a variable and we use it to name the final backup archive:

DATEX=`date +%d%m%y`

Final backup archive:

tar -zcvf /root/temp_bckp_$DATKA.tar.gz /root/temp_bckp

echo 'tar of all finished'

When we have all zipped together we are ready to send it over to the ftp backup server, I use ncftp utility which you can easily get on debian based distros using apt-get install ncftp or aptitude install ncftp.

ncftpput -u ftp_user -p ftp_password your-ftp-domain.com . temp_bckp_$DATKA.tar.gz

echo 'ftp finished'

For ftp server I personally use Linode services which are very cheap in the basic package, you can check their offers here

Complete shell script you can download from storage43 under this link
Happy backuping

1. Go to any page where you expect flash contant (e.g www.youtube.com)
2. Click the ‘install flash player’, unfortunatelly it’s not that easy (the reason I’m writing this post) but you can download it on you desktop. If this for some reason doesn’t work (I got some security errors, just use wget to get the file – wget already installed ).
3. Un-gzip it.
4. change to root on the console (su -)
5. copy the libflashplayer.so to the /usr/lib/firefox/plugins directory
6. restart the firefox
7. Enjoy flash movies!!

Good luck!

1. Install Java SDK and JRE 5, for some reason SS11 doesn’t work with version 6, you can however still keep the version 6 as the default one on the system.
2. Install GNU C/C++ compiler under Ubuntu:

sudo apt-get install build-essential

3. Download Sun Studio 11 software for Linux
4. Run the installer:
change to root (su -)
move the downloaded .bz2 file to the directory where you want to install the software (in my case /opt directory)
run:
tar -xjvvf studio11-lin-x86.tar.bz2v
./installer –nodisplay
5. Answer a few simple questions about installation
6. Don’t worry if sdk 1.4 was not installed.
7. Change one of the awk scripts:
go to /installdirectory/sun/sunstudio11/prod/scripts/ver.awk
and change the line:

FS=“”| |(|)|,|t”;
to:
FS=“”| |(|)|,|t”;

8. Add the studio’s bin directory to your PATH:
Edit .bashrc and add the following line:

PATH=/opt/sun/sunstudio11/bin:$PATH; export PATH

9. Run the newly installed Studio 11 with:
sunstudio
Note:
If you have more than one JDK available and e.g version 6 is your default one, run sunstudio command with the following flag:
sunstudio=’sunstudio –jdkhome ‘path-to-your-jdk5or4′ in my case alias sunstudio=’sunstudio –jdkhome /usr/lib/jvm/java-1.5.0-sun-1.5.0.11′
If that is the case add the alias to your .bashrc file:
alias sunstudio=’sunstudio –jdkhome /usr/lib/jvm/java-1.5.0-sun-1.5.0.11′
and run the command sunstudio as normal.
