everyone knows the standard C99 provide a boolean implementation, anyway a lot of compilers does not implement a real standard C99, but provide their own boolean type. So, to keep the portability i use a my own implementation.
If you are pedantic and you wanna follow the Linux Kernel Coding Style probably you do not like to use a typedef with a enumeration:

typedef enum {false, true} bool;

With this simple declaration you define a type “bool” that accepts only two arguments (since enum does this) one named false, and another true. Enum define also false as 0, and true as 1. In std C 0 is false. So you can use this boolean type to define if a condition is true or not (eg. if(true) { printf(“true!”); })

Happy coding!

No, i’m not kidding!
If you are configuring your own ssh webserver (such as openssh) make sure to disallow the root login.
So your users to get root privileges must log in with their account (knowing the password) and then invoke the “su” command that will ask the root password.
You can configure your openssh adding this rule in its configuration:

PermitRootLogin no

Then remember to restart the ssh server!
Thus if someone tries to gain root privileges, it will have to know two passwords.

Bye bye.

I’m new with blogs, I just started few months ago another blog on Google’s blogger but never written on it. So i decided to close it.
I’m an Italian teenager (19 years old) and I love the computer science and art (in any expression). I like music (symphonic music, metal, rock, a bit of pop), drawing, digital graphic art, and so on.
I like to follow magazines that talks about videogame developing and I love to write stories. I like mart people that never give up in the face of challenges.

Anyway, i started to like wordpress because everytime that i chosen a nickname already used, the form doesn’t clear password fields (i hate when it happens).

I don’t like to bore you people, so i stop here.
You’ll learn more about me asking or just following the blog but take in mind that i won’t write about me but about my world!

C ya then!
