In other words, no two Ethernet adapters will have same MAC address.
In Linux (Fedora/Ubuntu/Other flavours)
[neo@techpulp ~]# ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:A3:B2:01:5E:4B inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.0 ...

How to verify the integrity of a large downloaded file
Jan 29th
There are some algorithms like MD5 and SHA1 which generate unique digest for any given input. Basic idea is to find the MD5 or SHA1 digest of the file which is going to be downloaded and cross check the same after calculating digest after downloading the file locally. There are command line utilities “md5sum” and “sha1sum” to compute digest using MD5 and SHA1 algorithms respectively.
Typically the servers place a special file “MD5SUM” or “md5sum.txt” or “SHA1SUM” (file name may vary) in the same directory from where you are trying to download the large file. This “MD5SUM” contains digests of all More >
How to disable Ads using HOSTS file in Microsoft Windows/Linux/UNIX
Jan 21st
One way of avoiding online advertisements is to redirect all requests to Ad sites to locahost so that bandwidth is well utilized. It also results in faster browsing as it eliminates Domain Name Service (DNS) requests.

Map a directory with long pathname to a virtual drive in Microsoft Windows
Sep 27th
It is often very inconvenient to type long path names to move to a directory. Also sometimes code compilation fails if your command is taking more than certain length. In such cases, the base directory can be mapped to a Windows virtual drive so that the length of path can be reduced. For example “c:\mywork\myproject\release-10\” can be mapped to an unused drive “z:\“. Since then all files and directories present in “c:\mywork\myproject\release-10\” can be accessed using “z:\” as prefix.
Some old GNU compilation tools complain that command is too long when you have long pathnames and lot of command-line options. In More >
