My sysinfo program updated with new code. Even better than before!

http://www.securitronlinux.com/files/sysinfo.kdevelop-1.0.tar.gz. This is the link to my newly updated sysinfo program. This has code added using the sysinfo struct. This means that the memory and uptime information that is output is actually readable now. This is what the output of the memory and uptime section looks like now. homer@deusvult:~/Documents/sysinfo.kdevelop-1.0$ ./sysinfo 2 Ram & swap information. […]

A nice sample of code that will render a spiral on your terminal screen. This could be useful indeed.

This code sample will render a spiral on your terminal when you compile and execute it. Very interesting indeed. #include <sstream> #include <iostream> #include <string> std::string rle = "32 2@14 1n16 11@9 2@10 1n13 3@13 3@8 1@7 1n10 2@21 2@7 1@5 1n7 2@27 1@6 1@4 " "1n6 1@10 10@10 2@5 2@2 1n4 2@7 4@9 4@9 […]

Very cool code that prints a tick sign in asterisks. This is awesome C++ code.

This code prints out a tick sign using asterisks. I tested this code on Fedora 19 and gcc 4.8 and it compiles without any problems. #include <iostream> #include <iomanip> using std::cout; int main() { cout<<std::setw(8)<<"*"<<"n"; cout<<std::setw(7)<<"*"<<"n"; cout<<std::setw(6)<<"*"<<"n"; cout<<"* *"<<"n"<<"* *"<<"n"<<"*"; cout<< "n"; return 0; } This is what you should get when you compile and […]

Wrapping the printf() statement onto multiple lines in C and some other useful samples.

This code sample shows how we are wrapping a printf() statement onto multiple lines using backslashes. #include “stdio.h” #define hello “Hello World.” int main(int argc, char* argv[]) { printf(“This is a very long sentence we are handing down\n”\ “Mr smith, do you have anything to say for yourself”\ “?”); printf(“%s\n”, hello); return 0; } This […]

Miscellaneous Perl programming information. How to use for loops and printing HTML properly.

Opening a folder and listing the contents, and not listing certain files. This is the Perl code I was using on my very old Tripod.com website. opendir(DNAME, “$folder”) || die “I cannot open the requested directory $folder \n $!”; @dirfiles2 = readdir (DNAME); @dirfiles2 = sort(@dirfiles2); foreach $x2 (@dirfiles2) { if ($x2 eq “.”) { […]

Miscellaneous programming tricks with C.

This is a very simple Hello World program in C. int main() { write(1, “Hello World\n”, 14); } Counting how long a text string is. #include #include #define MSG “Hello Doctor, let’s get back to the TARDIS!” int main() { int g; g = strlen(MSG); if (g < 1) { printf(“The string is not very […]

The Linux kernel 3.3 has been released and among other features that have been included, there is some code from Google Android included. This is an interesting development, this does not mean that you can run Angry Birds on a Debian or Linux Mint system, but this could lead to something cool in the future. […]

My PHP code for my Linux pages index.

This code is on my http://securitron.securitronlinux.com page. It shows a random image and a random webpage link. <?php $time = strftime(“%A %d %B %Y. %r – %Z”); srand(time(NULL)); $day = rand() % 6; $string = sprintf(“<font size=\”2pt\”><p>Welcome to my website.</p>\n”); $links = array(“BejArray” => array(“0″ => “perl_code.php”, “1″ => “psx_doom.php”, “2″ => “cgi_code.php”, “3″ => […]

Useful C++ snippet. A better way to read in a sentence with STDIN.

This is a very useful C++ code snippet for reading in a line of text into STDIN. Hopefully this will be useful to someone. #include <iostream> #include <string.h> #include <sstream> using namespace std; int goku(void) { cout << "Hello, Please enter your name.\n" << endl; return 1; } int main(int argc, char **argv) { goku(); […]
