Enable PHP in Apache userdir in Lucid Lynx (Ubuntu 10.04)

If you’re using php + apache in Lucid Lynx (Ubuntu 10.04), you’ll notice that the php is disabled when you’re using userdir module (http://localhost/~yourusername). To enable it, open /etc/apache2/mods-enabled/php5.conf (alt+F2, then type gksudo gedit /etc/apache2/mods-enabled/php5.conf) and comment this part (add ‘#’ character in every line):


    
        php_admin_value engine Off
    

The result should be like this:

#
#    
#        php_admin_value engine Off
#    
#

Save the file, then restart the apache by typing sudo /etc/init.d/apache2 restart in terminal.

Check Your System Compiz Capability

There is a great script created to check whether your system is compiz ready or not. It’s called Compiz-Check.

Gathering information about your system...

 Distribution:          Ubuntu 8.04
 Desktop environment:   GNOME
 Graphics chip:         nVidia Corporation G70 [GeForce 7300 GT] (rev a1)
 Driver in use:         nvidia
 Rendering method:      Nvidia

Checking if it's possible to run Compiz on your system...

 Checking for texture_from_pixmap...               [ OK ]
 Checking for non power of two support...          [ OK ]
 Checking for composite extension...               [ OK ]
 Checking for FBConfig...                          [ OK ]

Checking for hardware/setup problems...            [ OK ]

If you got [ OK ] in every check, like mine, then your system is ready to run compiz. If something fails, go check the forum 😀

How To Install Oracle XE in Ubuntu 64 Bit

While you’re thinking by installing 64 bit linux you’re standing in the edge of new technology era, it sucks knowing our 64 bit system is less supported than the old 32 bit system. We have to install 32 bit flash since Adobe didn’t have the 64 bit one. We have to install 32 bit oracle xe since Oracle also didn’t have 64 bit version.

And now I will try explain how to install oracle xe into the 64 bit system, ubuntu way. Of course we couldn’t follow the guide from oracle, since apt-get will detect our system architecture and we won’t get the 32 bit packages list.

Before we start, make sure you have the 32 bit library installed. It’s in reposity, all you have to do is

sudo apt-get install libc6-i386

The next thing to do is download the files needed. It’s libaio_0.3.104-1_i386.deb and oracle-xe-universal_10.2.0.1-1.1_i386.deb. You could use wget for this

wget -c http://oss.oracle.com/debian/dists/unstable/main/binary-i386/libaio_0.3.104-1_i386.deb http://oss.oracle.com/debian/dists/unstable/non-free/binary-i386/oracle-xe-universal_10.2.0.1-1.1_i386.deb

After your downloads are finished, we continue to the main issue, forcing the package to be installed. You could try to install with usual dpkg -i first to make sure your system is really 64 bit.

sudo dpkg -i libaio_0.3.104-1_i386.deb

You’ll get error,

dpkg: error processing libaio_0.3.104-1_i386.deb (--install):
package architecture (i386) does not match system (amd64)
Errors were encountered while processing:
libaio_0.3.104-1_i386.deb

Added guide from Venka A

sudo apt-get install bc

To force the installation, do these

dpkg -i --force-architecture libaio_0.3.104-1_i386.deb
dpkg -i --force-architecture oracle-xe-universal_10.2.0.1-1.1_i386.deb

And after the installation is finished, you need to configure it

sudo /etc/init.d/oracle-xe configure

and edit your ~/.bashrc

ORACLE_HOME=/usr/lib/oracle/xe/app/oracle/product/10.2.0/server
PATH=$PATH:$ORACLE_HOME/bin
export ORACLE_HOME
export ORACLE_SID=XE
export PATH

And, voila, the oracle xe is ready. You could go to http://127.0.0.1:8080/apex from your browser.

Is Ubuntu 8.04 Ready for Non-Tech Savvy?

Maybe it’s very suprising to know that very easy task could be very complicated when it comes to non-tech user. Apparently, what we think easy enough is actually hard to do when the information isn’t clear. Content Consumer had a great experiment on how regular non-tech user (in his case, his girlfriend) doing things in Ubuntu 8.04.

The main issue with the desktop experience is that the geeky programmers and designers assume too much from the average user. They assume the user knows about the way in which programs are installed, or how the file system is set out. The average user will not go out of their way to google for help or even read the associated documentation that comes with Ubuntu and its default software. The little information pop-ups and guided wizards are critical to explaining how the user can accomplish the basic tasks they most probably are trying to do.
The Great Ubuntu-Girlfriend Experiment

Great article, and definitely great input for ubuntu development team.

Unable To Mount NTFS External Drive

Have you ever wanted to mount your external drive, but your linux box refused it? Most likely it was caused by you forgot to unplug / disconnect your external drive while you were in windows. Apparently, windows didn’t unplug / disconnect your external drive when it was turned off.

The logic way is restarting to your windows box, then unplug / disconnect your external drive. But it sucks. Why would we need to go to windows? The right way is using ntfsfix.

ntfsfix 

So, if your external drive is in /dev/sdb1, it would be,

ntfsfix /dev/hdb1
