Solved!: Someone liked my facebook page but I can't see him/her in the "likes" list

Problem: Someone liked my facebook page but I can't see him/her in the "likes" list. What is happening?

This happened to me many times and I went crazy. I even thought a friend was lying to me when she kept saying she "liked" my page, but I couldn't see her on the list when I clicked "See all likes".
She : "I unliked and liked again. Check now."
Me (after checking the likes list and not finding her there) : "Nice try! :/ I'm not forcing you to. If you dont like my page, dont "like" it. Simple. "
Then she sent me a screenshot that clearly showed that she had indeed liked my fb page.

If you are facing the same problem, here is what's happening. If the person who liked your page has not made his/her page likes public in their privacy settings, you won't be able to see him/her on your page "likes" list. i.e, If they have set their privacy level high for their page likes visibility, they will not show up on your list of people who have liked your facebook page.

This is rather stupid because, people might misunderstand each other, business page admins cannot send discounts to all their page followers, people can easily join a page and secretly monitor the activities without being noticed, etc etc.

Hadoop Error - WordCount : Unsupported major.minor version 51.0

Check out the error below. If you are getting a similar error while running a Java jar file on hadoop sandbox, the probable cause is that you compiled your code with a version of Java that's newer than the one running in the hadoop machine. So, recompile your code with a compatible jdk version and try again.

Comment below if this fixed your problem. Also let me know if it didn't or if you found a different solution. Thanks.

Sync Failed: Change the Evernote (Desktop) Password



So, you have changed your password for Evernote after the security issue. Now you are unable to sync the desktop Evernote application with the cloud servers. The error message displayed would be "Sync Failed". Here's how to start syncing again.


  1. Open Evernote desktop application (tested in Windows only, but Mac version should be similar). 
  2. Goto Tools>Account Info. In the dialog box, your current username will be highlighted in blue.
  3. Click the blue username (which is a link), and type in your new password in the dialog box that pops in.
  4. Click the Sync button to start syncing again.


That's it! Enjoy!
If this helped you, please leave comments or tips for others with the same problem.

Music Software Review : Vir2 Acoustic Legends vs Chris Hein Guitars vs Vienna Concert Guitar vs MusicLab RealGuitar

This is gonna be a short post (more like taking notes than an in-depth review!). Let's compare a few guitar VSTis!

First of all, Vienna Concert Guitar sounds bad and I think it's an old product as well. So, let's take that off the list.

Vir 2 Acoustic Legends HD
Pros:
Amazing Sound. Great attack and clarity. Good body to the tone.
Nice fret noise while playing.
Very realistic.
Cons:
Have to create different channels for different articulations (no mode switching with keys)
Chords - Mediocre

Chris Hein Guitars
Pros:
On the fly articulation switching with keys - muting, harmonics, hammer ons, etc.
Cons:
Relatively smudged sound
Tinny tone, lacks body. (Almost as if it was run through an EQ or amp)
Terrible chords

I compared both the instruments and their variations (nylon, steel, harmonics, banjo,...) side by side. These observations were consistent all over.

MusicLab's RealGuitar
Chord strumming is one area where both of the heavy weights abover are lacking. MusicLab's RealGuitar has high playability and shines in playing chords and strumming. Not as good as an actual guitar, but can get very close results through clever programming. Sound quality is good as well.

Final Thoughts:
For solos, I would use Acoustic Legends and for playing chords, RealGuitar.

Thanks for reading. Please leave your comments.

Update :
Ample Guitar blows everything else out of the competition. Check this out. It sounds crisp and has a high playability too. Sounds very realistic. They have produced libraries for other guitar models too, including electric guitars. Check them out. Great job, Ample Guitar!
