All you need is libgcal (sudo apt-get install libgcal0 in Kubuntu). This library provides Akonadi access to your Google account. Once it is installed you just have to configure it in Akonadi, and then you can access your Google contacts and calendar in KMail, KAddressBook, Kontact and Korganizer.

Unfortunately there is no sync option for Akregator and Google Reader yet.

Installing Ubuntu/Kubuntu with full disk encryption is absolutely easy. Unfortunately, installing it on a netbook with full disk encryption is not (at least not without a CD-ROM drive).

First of all, the desktop Ubuntu and Kubuntu install images don’t support full disk encryption. So get the Alternate ISO from here (Kubuntu users this way, please). Then create a bootable USB drive using UNetbootin.

Ready? Then boot your netbook from the USB drive, and proceed with the installation using this guide. You will be able to select your country, keyboard and configure your network. Then the installation will fail, because the installer won’t find a CD-ROM drive. Yuck.

Okay, if there is no CD-ROM drive we just have to mount the installer ISO. For this we copy the alternate installer ISO to a second USB stick, plug it into the netbook and give the system a few seconds to recognize it. Then we use alt+F2 to switch to a command line and hit so we can enter commands. First, we should make sure that both USB drives are there:

ls -la /dev/sd*

should return something like this:

/dev/sda
/dev/sda1
/dev/sda2
/dev/sdb
/dev/sdc

/dev/sda is your hard disk, /dev/sdb is the USB drive you booted from, and /dev/sdc is the second USB drive containing the installer ISO file (unless you have a second hard drive). Now you can mount the second USB drive to /mnt and the ISO image to /cdrom:

mount -t vfat /dev/sdc /mnt
mount /mnt/ubuntu-10.04-alternate-i386.iso /cdrom/
exit

Next, hit alt+f1 to return to the install menu and select “Detect CD-ROM”. The installation will proceed as described in the blog post above.

Have fun with Ubuntu 10.04! :)

That’s pretty easy:

#include <stdio.h>
#include <unistd.h>
 
int main(void)
{
  char input[BUFSIZ];
  /* just read it ... */
  read(STDIN_FILENO, input, BUFSIZ);
  /* ... and use it */
  puts(input);
 
  return(0);
}
