Compression Test

COMPRESSION TECHNIQUE TEST

Recently did a compressing test, had a folder with lot of text file.
The size of the folder was 10.0 MB

I made a TAR of it, it was 8.8MB and then i compressed it using GZip and it was compressed to 4.5MB, pretty impressive.

Then next i used bz2 and results were better 4.3 MB cool.

But then i tried compressing into 7z Format and can't resist myself writing this post here.
It was merely 2.3 MB wow! i mean too good. But directly converting the folder to 7z was making it around 4.6 MB but after TAR, 7Z won the race.

Short summary:
Real Folder Size 10.0MB
TAR 8.80MB
TAR.GZ 4.50MB
TAR.BZ2 4.30MB
7Z 2.30MB
(though it was done after TAR, extension was still 7z but it extracts to TAR).

Test done using 7Z open source software, on windows 7 ultimate 32BIT.
Setting of compression were ULTRA



( PS: zip stands no where)

Remove Facebook rotating image spam

Firstly i thought removing the cookies and cache will clear the stuff but it doesn't help. The attackers who made the JavaScript had actually utilized the email address given by Facebook which most of us don't have a idea exist even.

So we have to refresh that also after removing cookies and cache of browser. This came from the fact that when you see the status update it says via email, and thats the email they targeted.
Follow these simple steps to follow to remove the spam completely:-

1. Remove all the cookies and cache of browser + go to control panel -> network and internet ->delete browsing history and cookies. In the general tab click setting under browsing history as shown.
Click view files after the clicking settings tab. Delete all the files in there.
Now clear the cookies and cache that your browser stores from its settings.

2. After deleting all the files. Go to this link while you are logged in Facebook http://www.facebook.com/mobile/
Here you must see upload via Facebook. Click the picture above it. This is the email you can use to update status of your Facebook, post pics and much more.
Now, you have this.
Click on refresh your email, and it will ask for your permission that if you are sure to do it. Say reset and a final success message with a new email address will be given to you.

And you are done... no more rotating image spam to your Facebook wall.

Summarizing: 1. Delete all the cookies and clear browser cache.
2. Refresh the email of the Facebook.

Please comment if any problem in the steps or the spam persist.
