Update on Xubuntu livecd: Internet Bugs 2013-07-20 22:27
After a quite time I tried to remake the Ubuntu Linux Live CD according to the guide I posted before. After some digging I finally noticed the file /etc/resolf.conf didn't get created after livecd booted up.
As in the picture above, /etc/resolv.conf gets recreated by typing sudo dhclient eth0 in the console but some problems may still be there.
Reference on similar bug here:
Edit: This can fixed removing the /etc/resolv.conf if it exists before making the cd, and making a sym-linking in the chroot environment to other file as shown below.
ln -nsf ../run/resolvconf/resolv.conf /etc/resolv.conf

Using this script you can get a file to server and send it to the browser.
//get the file (e.g. image) and output it to the browser
$ch = curl_init(); //open curl handle
curl_setopt($ch, CURLOPT_URL, $_GET['url']); //set an url
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //do not output directly, use variable
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1); //do a binary transfer
curl_setopt($ch, CURLOPT_FAILONERROR, 1); //stop if an error occurred
$file=curl_exec($ch); //store the content in variable
//send out headers and output
header ("Content-Type: ".curl_getinfo($ch, CURLINFO_CONTENT_TYPE)."");
header ("Content-Length: ".curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD)."");
} else echo
'Curl error: ' . curl_error($ch);
curl_close($ch); //close curl handle
Warm Days 2011-07-17 12:53
In recent days you'd probably seen a quite high temperatures outside the window. At least in the city where I'm living it was surely hot.
But that's not a problem. There're alot of ways to spend time at home, more even when internet is fast and capable enough.

Alot of things can be found on Youtube and DeviantArt, and using Google more stuff could be found.

More content I'll probably add later, so that blog and the site would not feel abandoned after a some time.
