Head on over to the Glassfish admin panel (should be at localhost:4848 for most of you), go to Resources > JNDI > Custom Resources and create a new entry which looks like the following:

It is important to note here that if the name isn’t “value” (exactly), you will not be able to read this value via a InitialContext lookup in your Java code. You will get an exception as follows:

javax.naming.CommunicationException: Communication exception for SerialContext[myEnv={java.naming.factory.initial=com.sun.enterprise.naming.impl.SerialInitContextFactory, java.naming.factory.state=com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl, java.naming.factory.url.pkgs=com.sun.enterprise.naming} [Root exception is java.lang.IllegalAccessException: value cannot be null]

...

Caused by: java.lang.IllegalAccessException: value cannot be null at org.glassfish.resources.custom.factory.PrimitivesAndStringFactory.getObjectInstance(PrimitivesAndStringFactory.java:99)

Essentially, the InitialContext code attempts to read a property named “value” by default.

Here is the code you can use to read the constant you’ve added:

new javax.naming.InitialContext().lookup("mailConfig");

If you want to use a JNDI entry in a not so direct way (not name it “value”), you can read it using the following code:

javax.naming.InitialContext c = new javax.naming.InitialContext();
javax.naming.NamingEnumeration neb = c.listBindings("");
while (neb.hasMore()) {
  javax.naming.Binding b = neb.next();
  if (b.getName().equals("mailConfig")) {
    javax.naming.Reference obj = (javax.naming.Reference) b.getObject();
    java.util.Enumeration en = obj.getAll();
    while (en.hasMoreElements()) {
      javax.naming.RefAddr ra = en.nextElement();
      System.out.println(ra.getType() + "=" + ra.getContent());
    }
  }
}

Took me a while to get these code samples working. Doesn’t seem to be clearly documented. Hope this helps someone else :)

• Cat Mode: IIIOOIII
• Space Mode: OOIOIOIO (doesn’t work on Android)
• Pong Mode: IOOOOOOI
• Bacon Mode: IOOIOOOO
• Simone Mode: IIOIOOII
• Eightbit Mode: OIOIOOII
• Synth Mode: IOOOIOOO
• Song Mode: IIOIIOII
• ASCII Mode: OIIIIIII
• Bowling Mode: OIIIOIOI
• Rocket Mode: OIOOOIOI
• Burger Mode: OOIIIOOI

So head on over to the Google I/O 2013 website and try these out :) Note that Synth Mode will work only if you have audio enabled and Space Mode will not work on Android devices.

Go check it out! I bet that you’ll love it so much that you wouldn’t mind paying $20 for it! ;)

convert L: /fs:NTFS

This converts L: to NTFS without removing any data from the drive. This process, all in all, requires less than 3 seconds.

Here are some sample scripts

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -command “& ‘C:\Users\Karun\My Scripts\filelist.ps1‘”
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -command “& ‘C:\Users\Karun\My Scripts\filelist.ps1‘” “.” “true”
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -command “& ‘C:\Users\Karun\My Scripts\filelist.ps1‘” “.” “true” “true“
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -command “& ‘C:\Users\Karun\My Scripts\filelist.ps1‘” “H:\Movies\HQ”
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -command “& ‘C:\Users\Karun\My Scripts\filelist.ps1‘” “H:\Movies” “true”
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -command “& ‘C:\Users\Karun\My Scripts\filelist.ps1‘” “H:\Movies” “true” “true“

Add a shortcut with any of those and it will get the job done! ;)

If you’re having trouble executing the script, you should consider signing your PowerShell scripts. Scott Hanselman has written a great post on how to do so. Go read it! You could simply Set-ExecutionPolicy to Unrestricted but then you’d be leaving your system open to attacks. Don’t blame anyone but yourself if you run someone else’s unsafe code and screw something up :) You have been warned :)

There are tons of things that need to be made configurable but first, I’d rather finish the SMS code that I had partly developed a while back along with the functional e-mail notification script. The only issue with the SMS functionality code is that it’s not stable since I scrape data onto the provider’s site (since they don’t provide a proper API :( oh well..). Once I get this working well, I’ll upload the SMS source code along with instructions on how I run it.

More posts, coming soon!

If you read the XBox help on how to remove a payment option, they ask you to go to “Payment & Billing” and this site won’t be accessible either.

Your best bet is to go to commerce.microsoft.com and then to their “payment options” page. Here, you will see your credit card. Click on it and click remove. Add a new payment option if you please. After this, you should be able to access xbox.com and buy things on your xbox

I ported over data and my database after cleaning up the infections. I have, however lost some of the uploaded images from my past posts so any issues there are regretted :( These images are gone from my Dreamhost server and hence can’t be ported over.. oh well :’(

Thanks once again to those who helped me with Dreamhost.. let’s welcome the movement to our very own server, Bumblebee! :)

1. Insert your UFD and make sure all your data is backed up because we’re going to format it.
2. Run command prompt
3. Open diskpart (will ask for elevation)
4. Type “list disk”
5. find what disk is your USB based on the size. Mine is number 3.
6. type “select disk 3″ (where 3 is the number that the system associates with my flash drive)
7. type “clean”
8. type “create partition primary”
9. type “select partition 1″
10. type “active”
11. type “format fs=ntfs”. Might take some time based on the size of your drive
12. type “assign”. This gives your drive a letter on the system.
13. type “exit”. Closes diskpart.
