Newer Yahoo! Messenger Protocol on Pidgin on Debian Lenny 5.0

Yahoo! has changed authentication method of Yahoo! messenger protocol, which is not supported in Pidgin (Version <>= 2.5.7) supports newer Yahoo! Messenger Protocol. But Debian 5.0 Lenny repository has older pidgin (2.4.3). We can install newer pidgin, in the following steps:

## download latest pidgin from pidgin.im (at this time 2.6.3 is latest)
$ wget http://sourceforge.net/projects/pidgin/files/Pidgin/pidgin-2.6.3.tar.bz2

## extract files using tar
$ tar -zxvf pidgin-2.6.3.tar.bz2

$ cd pidgin-2.6.3

## Configure, Compile, and make
$ ./configure --disable-screensaver --disable-vv --disable-avahi --disable-tcl --disable-tk --prefix=/usr 
$ make
$ sudo make install

Now you can use newer pidgin with newer Yahoo! Messenger. :)
Enjoy Yahoo!

Find Files Created Between 2 Times

In order to find files created between two times (start hour and end hour). The required hours are hours from current time. For example,

Current time = 2 PM = 14:00

If you want file created between 9 AM and 12 PM today, the start hour and end hour are:

Start Hour = (14 - 9) = 5
End Hour = (14 - 12) = 2

Hence required command is:

$  ./find_files_between_times.pl /path/to/dir 5 2

The Perl script which does this is given below:-

#!/usr/bin/perl -w
