Hello Guys,

Idea just clicked to start a thread "Did You Know". Let us start sharing 1-liners stuff here which we come across everyday. What ever you think that others might not have come across, please do share.

Here goes mine....

Did You Know that SYM is for Security Advisories Relating to Symantec Products? (Just like MS is for Microsoft Products)
e.g. (SYM08-020)

Well since the name is Did you know...
I think no harm in telling something without thinking how many people would know it. :D
So lots of people might know this
any ways here it goes
Xming:Xming allows you to easily connect to remote *nix machines using the X protocol. It comes with clipboard integration and fullscreen support.
Here is the link

Every Java .class file starts with the string "cafe babe". This signature identifies the Java binary class format (and
incidentally serves as a lasting -- but largely unrecognized -- tribute to the hard working baristas who kept up the spirits of the developers building the Java platform). :rolleyes:

Unlike normal captcha, recaptcha has two words. Usually one of the word is a stranded computer generated one. while the other is some scanned word from book. Whats happening is that google and other big companies are scanning books. and converting them to digital form for their own good. BUT instead of spending money on it. they are getting millions of users to fill them for FREE.

So when one user enters one (computer generated) word correctly it accepts the other one from scan. So you can technically write anything in place of other and it will be still be accepted.

In some programming languages you get strange results when counting the number of characters in a non-ASCII string: they’re assuming the string is ASCII and counting the number of bytes it takes in memory. To count the characters accurately the language has to be told what encoding the string uses and it has to know how to parse that encoding.

The 3 time stamps *nix keeps are:
1. atime : The last time file was opened or executed
2. ctime : The time the inode information was updated (chmod, chown etc does that). ctime also gets updated when file is modified
3. mtime: The time file was closed after it was opened for write

So all the above stated time stamps change per the usage and hence *nix does not have file creation time

Command to see mtime #ls -l
Command to see atime #ls -lu
Command to see ctime # ls -lc

Please correct me if I am wrong.

I am not sure how many of you guys know.

Did you know:

Intel stands for 'Integrated Electronics'.
AMD stands for 'Advanced Micro Devices'.
Java was 'Project Oak'.
Microsoft stands for 'Microprocessing software'.
Word Processor (as in Microsoft Word) does not refer to 'word as in sentence' but, 'word as in size'.
The word 'Pentium' has its inspiration from hack-culture which used the word 'pentia' to refer number 5 and to imply x586 and trademark a name, they wanted something unique and must also refer to something 'strong', thus, Titanium. Finally, it was: Pentia+Titanium = Pentium. 486 were not pentium :)
Name 'Apple Inc' was decided over supper table while biting on apple thus, logo is bitten apple and not full apple.

Thats all I can think of right now...

TFS all :)

@b0nd:
Most of the *nix file-systems don't maintain any creation time of files, but however, ext4 filesystem does support all four timestamps: atime, ctime, mtime & crtime.
You can get the date of file creation time on ext4 filesystems with "debugfs" and "inode number".

http://img1.imagehousing.com/44/6ca867be8e3645407da418c5855f8437.png

The output of the command "sudo debugfs -R 'stat <2099350>' /dev/sda6 is truncated in the spited window below.

use the following command in the url box >>

chrome://browser/content/browser.xul


P.S: I think maybe we can make a fork bomb like DOS attack from this ..will try some time :cool:

fork bomb i am not sure if that would be coz all windows will be under same process....
only firefox could be crashed if we open firefox and its home page is set to
chrome://browser/content/browser.xul
i hope that should do the trick

yups .. sorry ... I meant to say that we can crash firefox in the same way as fork bomb does by creating new sessions recursively.

yups, a friend of mine showed it to me a long time ago .. we kids thought that hacking is done by only one tool --> Nmap :p

B/w I also found that Armitage was filmed in the television series Breaking In . There was one shot where it shows the guy using it. Guess, the director thought that Armitage's GUI was a great eye-candy :D

Already facebook is asking phone number for security what is the use of recaptcha in security. We can grab the complete information of the user by phone number details.

Usually the 'now' has been scanned by multiple OCR programs and they don't match. So just you entering ni**er will not alter the book/paper etc. The reCAPTCHA system will ask multiple humans to identify that word and accept it only if it matches.

Web Console in Firefox
Beginning with Firefox 4, the old Error Console has been deprecated in favor of the new, improved Web Console. The Web Console is something of a heads-up display for the web, letting you view error messages and other logged information. In addition, there are methods you can call to output information to the console, making it a useful debugging aid, and you can evaluate JavaScript on the fly.

Just Press Ctrl + Shift + K

https://developer.mozilla.org/en/Using_the_Web_Console

Thanks to cons0ul for pointing me to this.
