Hacking

Hi, do you need very highskills like programming to hack some smaller sites for example?

I have no idea how to do it at all.

Are there some manuals for beginners? What tools do you need for?

Or better just demonstrating pages, where you can test you hacking skills (of course for very beginners;) ?

HOW TO HACK IN 5 EASY STEPS:

1. GREAT REALIZATION I: Realize that anything, ANYTHING that has to do with software, computers, or anything "digital" is reducible to lists of bytes, i.e. lists of numbers that can range from 0 to 255.  "Anything" means just that, programs, data, etc.
2. Learn about all the hardware and hardware systems you can, down to the schematic level if possible.  Nothing gets in and out of hardware without some sort of communication protocol. which is usually how software and hardware are connected.  So especially study hardware's communication protocols.  You aren't done with this step until you can build a multi-core superscalar CPU with built-in memory controller and video hardware from sand off the beach and wires scavenged from broken, old televisions.
3. Learn about all the data formats and programming languages you can.  Including assembly.  You aren't done with this step until you can write a 100% bug-free C compiler in assembly for ALL currently available CPUs.
4. GREAT REALIZATION II: Realize that writing programs and designing systems that do exactly what the programmer wants without intended side effects is generally an impossible feat, given the sheer complexity of 2 and 3. 
5. Once you have truly achieved the two Great Realizations, if the knowledge you've pursued in 2 and 3 are sufficient, then you can "hack."

IT'S THAT EASY!
