The first time I touched Linux was during my graduate school days. In 1997 one of my colleagues, Dr. Venkatesh Raghvan visited us in Tokyo University and we discussed the possibilities of serving maps on Internet using GIS and Relational Databases. He told many good things about the funky operating system called Linux and we decided to give it a try! Venkatesh and I went to Akihabara and bought no less than ten different distros (In those days internet -- at least in Japan was too slow to download iso's though we had a cd-burner in the lab!) including Slackware, Redhat, Debian etc and a external SCSI hard drive. We spent the whole next day in a doomed attempt to get one of the distros going in my (primarily Windows NT 3.5) computer. Linux got installed alright, but it always gave up on us when we tried to get the X-server started. After a day we had to give up! That is how friendly the Linux OS those days was! Of course we were trying to get the OS and the X Windows running.

This story came to my mind when I was sitting in front of the home computer running the latest Ubuntu Linux incarnation -- Edubuntu. A week ago we had another very friendly linux distribution -- Linux Mint, but we decided that we need a different system and Chandani downloaded the Edubuntu ISO, burned to a DVD and installed within an hour! We don't give seconds thoughts to the way these operating systems recognize all the hardware of the computer (sound, printers, card readers, external storage, etc., etc.) and configure itself without ever bothering the person in front of the computer! Our daughters use Linux at home to play games and access children's web sites. Recently I received a laptop running Windows 7. I installed Linux Mint side by side. After using the computer for about six months, I realize that I boot Windows 7 for only one purpose -- to use a Dutch Language learning CD-Rom that uses an ancient version of macro-media (yes! that was before adobe bought them!) flash. Especially when I travel, my Linux installation is a big relief as I don't have to worry that much about getting my computer infected with viruses from various Flash Memory sticks.

A lengthy journey

Linux came here via a long and hard path. Almost every year since 1997, I used to try installing Linux hoping that it would run better. Of course it did, even in 1998 the basic system - the OS and the X-server could run on a sufficiently mainstream PC. But, many integrated devices (e.g. sound) and peripherals (e.g. printers) did not work very well. But each time, things improved over the previous. By the time I was running atmospheric models (MM5) on RedHat 7.3, in 2002, things have become sufficiently painless in the PC department. Laptops were still difficult due to their often exotic hardware.

I felt sad when Redhat Inc. in 2003, gave up RedHat Linux, the most popular Linux variant at that time, and restricted itself to serving its corporate customers with RedHat Enterprise Linux. I chose the upgrade path of Scientific Linux for my workstations running atmospheric models. Killing RedHat gave Fedora OS to the community -- but that particular `hat' never felt the same for me!

Then came Ubuntu in 2004. I stubbornly stuck with my Scientific Linux until 2006. I read somewhere (probably in distrowatch.com) that Ubuntu was not a bad system and gave it a try. Boy, that was easy! I never had to suffer though the dependency hell of RPM packages. The Debian-based apt-get system was a pleasure to use. Later I even converted my server machine to Ubuntu. Today all my Linux installations are Ubuntu variants (Mint, Edubuntu and Ubuntu).

Today I feel that Linux has finally arrived to the level that every one can use. In fact, in my opinion, it has become much easier, safer and fun system to use compared to Windows. It was not that even a few years ago -- but today it is!

I am not an expert on computers or operating systems. If reviews on Linux are needed there are better places to go. However, in these pages I will start what will be a log of personal experience with this beautiful product.

Software for free, at your fingertips

Installing software has never been easy. Say, you need a GIS system: Qgis is an excellent program. Just type qgis at the terminal. When I do that, my computer tells me:

The program 'qgis' can be found in the following packages:
 * qgis
 * qgis-plugin-grass
Try: sudo apt-get install <selected package>

So, I type the following on the terminal:

sudo apt-get install qgis

and go for a coffee. In a few minutes, a complete gis system is installed and ready for use!

There are thousands of common and not-so-common programs readily available in Ubuntu package sites around the world. Getting and installing a new software often involves only typing:

sudo apt-get install <name of the software>

Talk about user friendliness!
