First install golang, SDL and the golang SDL package. The following is for Ubuntu 12.04:
sudo apt-get install golang-go
Install SDL libraries:
sudo apt-get install libsdl1.2-dev
sudo apt-get install libsdl-mixer*
sudo apt-get install libsdl-image*
sudo apt-get install libsdl-ttf*
sudo go get -v github.com/0xe2-0x9a-0x9b/Go-SDL/...
Then create the following go program. This write random pixel data to the screen directly. If you save it to main.go you can execute it with:
go run main.go
Here’s the code (please note there’s probably a lot wrong with it, it’s my first go program):
package main
import (
"github.com/0xe2-0x9a-0x9b/Go-SDL/sdl"
"log"
"unsafe"
"math/rand"
)
func draw_point(x int32,y int32,value uint32,screen* sdl.Surface) {
var pix = uintptr(screen.Pixels);
pix += (uintptr)((y*screen.W)+x)*unsafe.Sizeof(value);
var pu = unsafe.Pointer(pix);
var pp *uint32;
pp = (*uint32)(pu);
*pp = value;
}
func main() {
var screen = sdl.SetVideoMode(640, 480, 32, sdl.RESIZABLE)
if screen == nil {
log.Fatal(sdl.GetError())
}
var n int32;
for n=0;n<1000000;n++ {
var y int32 =rand.Int31()%480;
var x int32 =rand.Int31()%640;
var value uint32 = rand.Uint32();
draw_point(x,y,value,screen);
screen.Flip();
}
}

apt-get install apache2
apt-get install libapache2-mod-perl2
apt-get install perl-debug
apt-get install libapache2-mod-perl2-dev
apt-get install libapache2-request-perl libdatetime-perl
Edit /etc/apache2/sites-available/default, add:
<Location /perl/>
SetHandler perl-script
PerlHandler ModPerl::PerlRun
Options ExecCGI
PerlSendHeader On
allow from all
</Location>
Install the CGI module:
cpan install CGI
Create a directory /var/www/perl. Add a script, for example:
#!/usr/bin/perl
use CGI; # load CGI routines
$q = CGI->new; # create new CGI object
print $q->header, # create the HTTP header
$q->start_html('hello world'), # start the HTML
$q->h1('hello world'), # level 1 header
$q->end_html; # end the HTML
Call it something like hello.pl. Try to access http://server/perl/hello.pl, everything should work correctly.
