Sang Shin is offering a free ten-week course on Ajax, starting on the 4th of August, 2006.

It will cover fundamental technologies and some of the popular libraries and frameworks out there. Looking at the curriculum, there's a Java focus on the server-side -- DWR, Wicket, JMaki, JSF, and GWT...

Below is an abstract of what it involves:

o The Web is going through the second wave of its evolution and some people call it Web 2.0. Whether Web 2.0 is considered a hype or not, there are indeed a set of concrete technologies such as AJAX (Asynchronous JavaScript + XML) that make the Web of today a lot more interactive, responsive, exciting and useful than it used to be.

Nagios is a host and service monitor designed to inform you of network problems before your clients, end-users or managers do. It has been designed to run under the Linux operating system, but works fine under most *NIX variants as well. The monitoring daemon runs intermittent checks on hosts and services you specify using external "plugins" which return status information to Nagios. When problems are encountered, the daemon can send notifications out to administrative contacts in a variety of different ways (email, instant message, SMS, etc.).

I have an unused partition and want to install Ubuntu Dapper on it. On reading through the docs it seems possible to install it from an existing linux/unix box.

1. My current partition looks like below, of which "/dev/hda2" primary partition is unused:
   

   /dev/hda1               1        1044     8385898+   7  HPFS/NTFS
   /dev/hda2            1045        4699    29358787+  83  Linux LVM
   /dev/hda3            4700        4712      104422+  83  Linux
   /dev/hda4            4713        7296    20755980    5  Extended
   /dev/hda5            4713        7296    20755948+  8e  Linux LVM

If you are using Widows only to back-up your DVD videos... there is good news. You can install DVD Shrink on Linux using wine and do the same.

I have outlined the steps taken to do so on FC5:

1. Use yum to install wine if you don't have it installed already:
   

   # yum --enablerepo=extras install wine
   

2. Configure wine as a user:

   $ winecfg
   

   Select "Applications -> Windows Version -> Windows XP"

   This is the tricky part, as FC5 mounts the DVD automatically with the title of the DVD instead of using the same mount point, so you will need to map the drive manually each time for a different DVD.

   • Insert DVD Video.
     
   • Go to the Drives tab of the "Wine Configuration" window.
     
   • Click on the "Add" button and "Browse" to the mounted DVD in the "/media" path.
     
   • Click on "OK" button at the bottom once finished.
     
   • When listing the contents of the "dosdevices" you should see something like below:
     

       $ ls -l ~/.wine/dosdevices
       lrwxrwxrwx 1 sandip sandip 10 Jun  8 22:58 c: -> ../drive_c
       lrwxrwxrwx 1 sandip sandip 17 Jun  8 23:06 d: -> /media/DVD_VIDEO/
       lrwxrwxrwx 1 sandip sandip  1 Jun  8 22:58 z: -> /
       

     You could also manually create a symlink instead:

       $ ln -s /media/DVD_VIDEO ~/.wine/dosdevices/d:  
       

3. Download and install DVD Shrink.
   

   $ wget http://linuxweblog.com/downloads/packages/dvdshrink/dvdshrink32setup.zip
   $ unzip dvdshrink32setup.zip
   $ wine dvdshrink32setup.exe
   

4. Launch and configure DVD Shrink Preferences as below:

   $ wine 'C:\Program Files\DVD Shrink\DVD Shrink 3.2.exe'
   

   • Select "Edit -> Preferences..."
     
   • Disable audio and video preview.
     
   • Disable burining with nero.
     
   • Click on "OK" once finished.
5. Create ISO with DVDShrink and write the ISO to your DVD using cdrecord or Nautilus CD/DVD creator.
