Using binary copy in Windows for hiding a rar file within a jpg image file.

A command as:

copy /b img.jpg + src.rar img.jpg
can be used to hide src with the image file. This command results in a binary copy of the image and the src. rar file (which can contain your data which is to be hidden) into the img.jpg.

While opening, you can just rename the  image file with winrar and things will work out fine.

Neat trick to bypass blocked websites

Is a particular website blocked at your school or workplace. Try this. Type the ip of that website in the browser and lo and behold it works. IP can be usually discovered by pinging the website. 

Now what if the command prompt is blocked?
First, to get a new command prompt, open Notepad and type: Then, save as “cmd.bat”. You now have a command prompt. Now, open the command prompt and type “ping” to find the IP address of that website. Enter the website into the browser and you will officially have impressed all your friends.
Now what if ping is blocked on your network? How do you get the IP then?
- Try nslookup. See the example below:
