Right after unpacking it, I inserted the DVD and was wondering “They ship a whole DVD with just 2 Files, not more than 3 MB of size?”

The thing is: The DVD has a file system called UDF which supports hidden files and directories. Unlike with normal filesystems in linux, even a ls -lah does not show these files.

1. Unmount the DVD

Make sure to unmount the DVD first.
Close every filemanager and console that has the DVD folder open.
In my Ubuntu installation, the DVD is mounted to /media/cdrom0

Do the following in a console

sudo umount -f /media/cdrom0

If it does not work, look which processes still have a lock on the directory using

sudo lsof /media/cdrom0

and kill those.

2. Mount the DVD correctly
First, get your own user Id. Most of the times its just 1000.

id

should return something like this

uid=1000(domdorn) gid=1000(domdorn) groups=4(adm),20(dialout),24(cdrom),46(plugdev),103(fuse),104(lpadmin),114(admin),118(sambashare),1000(domdorn)

Note the values of uid=… and gid=…. (here both are 1000)

Next, mount the DVD the following way:

mount /dev/cdrom /media/cdrom0 -o uid=1000,gid=1000,unhide,umask=0000

unhide makes linux show the hidden files on the dvd, uid/gid makes sure you’re allowed to read the files.

3. Start the Installer
Now try to start the installer: Open a console, change to /media/cdrom0 and start it.

cd /media/cdrom0
wine Installer.exe

If you’re lucky, it now works out of the box and you are finished.

If not (like me), it simply does nothing and we have to do the following.

4. Copy the DVD
If the Installer does not work out of the box, create a folder on your filesystem, e.g.
~/.wine/drive_c/sc2install
and copy the whole DVDs contents to this directory. After this is finished, try to start the Installer from there.

Log into your Battle.net Account.

http://www.battle.net

and Add your CD-Key to your Account. If you don’t have an Battle.net Account yet, create one, you’ll need it anyway.

After you’ve added the Game to your account, download the Windows Installer.
Start up the downloaded installer and select a folder in your wines Drive C. Let it download a few bytes and then quit the installer.
Now copy the files

Installer Tome 1.MPQE.part
Installer UI 1.MPQ.part
Installer UI 2.MPQE.part

from /media/cdrom0 to the created folder. In my case its ~/.wine/drive_c/sc2download/SC2-WingsOfLiberty-enGB-Installer

Now startup the downloaded installer again.
It should start checking the downloaded files (you might not see a difference in the progress bar, but the CPU goes up, watch with “top”).
After the file check is finished, the installer should start.

• Validating an Email Address in JSF

It shows, how this would have been done in the old JSF 1.1/1.2 ways… But we’re in 2010 and do it now the following way:

...
            


                    
                    
                        
                        
                    
                    
                

....

....

What does this code? It sets the email property of the bean loginRegisterBean after the user changed the value and clicked out of the field (through ajax). It automatically validates the email address through the f:validateRegex pattern and updates the message ( h:message ) if the validation failed.

The Bean looks like this:

@Named(value = "loginRegisterBean")
@SessionScoped
public class LoginRegisterBean implements Serializable {

....

     // also apply these restrictions on the property itself!
    @Pattern(regexp = ".+@.+\\.[a-z]+")
    @NotNull
    private String email;
....
    public void emailChanged(AjaxBehaviorEvent event) {
// do something
    }
...
    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }
}

when trying to inject the Mail-Session into your bean, try to do it the following way

@ManagedBean(name = "registrationController")
public class RegistrationController {

@EJB
RegistrationServiceImpl registrationService;

@Resource(type = Session.class, name = "mail/projectMailSession", mappedName = "mail/projectMail")
Session mailSession;

private Member member = new Member();

....

private void sendRegistrationEmail(String activationCode) {
try
{
Message msg = new MimeMessage(this.mailSession);
msg.setSubject("Project X: Activation needed! ");
msg.setSentDate(new Date());
msg.setFrom();
msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(member.getEmailAddress(), false));
msg.setText("Welcome at Project X! \n" +
"Aktivierungscode: "+ activationCode + "\n\n bis bald!");
Transport.send(msg);
}
catch (MessagingException e)
{   e.printStackTrace();  }
}

The important part is bold printed: You have to

1. inject the mail-session with the @Resource annotation,
2. specify the class you want (type = Session.class),
3. specify an alias for the jndi-name with this object ( here “mail/projectMailSession” )
4. and specify the jndi name you used to specify the mail-session in the administration backend (I used “mail/projectMail”).

JetBrains just announced, that upcomming IntelliJ Idea 9 will be made open source.

Eclipse and NetBeans now definitely have to fear “The most intelligent IDE” in the world!

Hooray at JetBrains!

So, I was wondering, if there is a way to migrate my stuff from the “Free Gmail” to the “Google Apps Gmail”, but my (initial) searches ended up with no result, so I did it my way:

1. Open two browser windows, one with your Gmail-Account, one with your new Google-Mail account
2. Migrate contacts first
   1. Export the contacts from your GMail account to google’s  csv format
   2. Import them into your Google-Apps account
3. Recreate your Labels in your new Account
4. Enable IMAP on both, your Gmail Account and your Google-Apps Gmail Account
5. Use this Migration Tool: http://www.thamtech.com/blog/2008/03/29/gmail-to-google-apps-email-migration/
   • Make sure you use the latest version of imapsync, >= 1.286 has special Gmail support
   • I had to rename my labels and remove square brackets ( [ ] ) from them
   • I removed the first two regex-lines in tylers script, because I want to preserve the original addresses inside the mails.
6. Recreate your filters: Unfortunately there is no import/export feature for filters, so you have to recreate them by hand
7. Setup forwarding of mails from Gmail to your Google-Apps Gmail.

This way, I converted nearly all (around 10 messages are missing, according to the “manage labels” view) my gmail-email to my google-apps gmail account. In case, I ever need those 10 mails, I still have my normal gmail account to look for them there.

Happily, I found a tool that does exactly what I wanted:
It’s called “X Do Tool” or short xdotool . A simple make did it for me and I had my script ready.

First I tried to do clicking by

./xdotool mousedown 1 ; ./xdotool mouseup 1

( 1 is left, 2 middle, 3 right mouse button, according to your xorg.conf ), but then I found that a simple ./xdotool click 1 would also do it;

So for “cheating” at this stupid “who can click the most times in 30 seconds” game on facebook, simply open a console next to your browser, type

while true; do xdotool click 1; done

and depending on the speed of your x-server you get far more than 1000 clicks / 30 seconds. sadly they have some manipulation detection or something like that so you would have to add some “sleep xx” calls to your loop

I’ve stopped playing around this while having reached around 480 clicks, being placed second after an aquaintance of mine.

Happy “cheating”
