Here is a useful tip for web designers and developers who want to test their website with different versions of Internet Explorer.

As a web designer you’ll have to test your website with multiple browsers in order to check the correct behavior of your pages on different platforms.
Whether you like Internet Explorer or not, you’ll have to carefully test your new pages with this browser, which sucks doesn’t respect many international web standards, but unfortunately is still the most popular among internet surfers.

If you update your copy of Windows XP, IE 6 will be replaced with the new version 7. Anyway you may need also the previous version (which is currently the most wide spread) to test your web pages.

Now there is a simple way to install standalone copies of Internet Explorer!

Just download the multiple IE installer at this page: http://tredosoft.com/Multiple_IE

You’ll be able to easily install old Internet Explorer versions (3, 4.01, 5.01, 5.5 and 6) and run them side by side with IE 7.

The installer currently supports only Win XP and doesn’t work under Vista.

Xubuntu Linux on iMac G3

Today I decided to install Linux on my 500Mhz iMac G3 with 256 MB RAM. Although this mac is quite old, it can still be employed for internet surfing or as a local web/file server. Its design is terrific and the machine is compact, silent and easy to move.

I am oriented on debian-based distros, so I chose to install Xubuntu (7.04), a light linux distribution (Ubuntu-flavoured), which features Xfce desktop environment instead of Gnome or KDE (you can download Xubuntu freely from the official website: I downloaded the Alternate Install CD, which is easy to install as the Live CD version, but requires less ram).

The installation went smoothly and the only problem I encountered was the freezing of X server at startup; I googled for some information and found several posts which explained how to solve the issue changing various parameters such as monitor horizontal and vertical sync in xorg.conf, however I wasn’t able to start correctly the X server and have the graphical interface working (everything seemed extremely slow and Xfce was frozen) .

Eventually I found a solution and decided to post it here as Mac configurations are quite standard and someone else with this machine could run into the same problem:

  • If X or Xfce freeze (or crash) on the first restart after installation you’ll be able to access the terminal through the shortcut ctrl+alt+F1 (don’t wait too much time to access the terminal as the mac could freeze completely and you’ll have to restart it)
  • login into the system typing your user and password, then type:
    sudo su
    and repeat your password in order to obtain root access
  • now open xorg.conf with nano, a simple text editor:
    nano /etc/X11/xorg.conf
  • go to the section “Module” inside xorg.conf file and place a comment adding the # symbol before the line Load “dri”:
    # Load "dri"
  • Save the xorg.conf file with the shortcut ctrl+o and press Enter
  • Reboot the system typing
    reboot
    and everything magically will work :-)

Disabling DRI (Direct Rendering Infrastructure) couldn’t be a very elegant solution, however, if you don’t plan to use 3D games or OpenGL applications (don’t think this iMac model would run them adequately anyway), this solution makes your old iMac G3 work like a charm and you’ll be able to perform home and office tasks such as surfing the internet, playing music or writing a document with your new brand, free operating system.
