Japanese White Eye on a Cherry Blossom Tree
Here is the first picture that I sold via a micro-stock company. Hopefully this is the first of many.

Getting Virtual with VirtualBox
Until recently all of my VM projects had been done in VMWare Server, as this version is available as a free download from VMWare. After upgrading my Linux Box to Ubuntu 8.10 I needed to reload my VM software but I was having some issues getting VMWare server to install correctly. Not wanting to spend a lot of time trying to get the software to work and aware that other options are available I started looking around and found VirtualBox.
VirtualBox is an open source VM software that is available free for download for Windows, Linux, Macintosh and OpenSolaris from Sun Microsystems. The current version is 2.1.0. The VirtualBox website has packages for the following Linux distributions and many packages are available for both i386 and AMD64 architectures.
As I am using Ubuntu 8.10 I downloaded the i368 deb package and installed it on my system. The install was very straightforward and did not require and special installation steps other than logging off and logging on again to get the program to appear in the Applications -> System Tools menu.
Coming from a VMWare background, getting started with VirtualBox was a snap. Setting up a new virtual machine is done very easily using the provided wizard and has all of the common configuration items. New VMs can be install directly from the ISO image without the need to burn a CD or DVD.
Virtualization is a great way to test out new Linux versions or to learn the internal workings of a Linux distro without reloading your primary machine. If you are interested in getting into virtualization at home and are looking for a good open source solution, VirtualBox may be the way to go.

Linux CLI for fun: du
One of the best things about Linux is the power of the Command Line Interface (CLI). Many new Linux users making the transition from either Windows or Mac to Linux may have difficulty getting away from the GUI method of doing things and into the CLI but there are times when the CLI is the only way to perform a particular task or just the fastest way. The only way to get proficient in the CLI is to open up a terminal and get some practice.
A good example of a CLI command that is very useful is the du command. I am always interested in how much disk space a particular file or folder is taking on my hard drive. This is especially important to know when writing data to removable media that is limited in size such as a CD or DVD. There is a GUI method which is to select the view that shows the details of files and folders but the only the size of the files is show and not the folders in a particular directory. What if I want to know the size of a bunch of folders in a directory and what if I want that information in a text file for later use.
The du command is a great tool for doing this and only takes a few seconds to use. Just cd to the directory that you want to get information on and type du. Actually it is not that easy as the display you get is the size of each and every file in the directory and every sub directory. Since this very is not very effective, lets break this down a little more.
First you can add a file or directory name to the du command to only find out the size a that particular file or directory. For example du thefile will give me the size of the file named thefile. The size is listed in KB but since there are no tags or legend this is not readily apparent. To fix this add the -h argument to the command so the line would look like du -h thefile.
Next when looking at folders, if you only want to so the total size of the parent folder and not have the sub directories listed, add the -s argument to the command so the line would look like du -hs thedirectory.
There are many more arguments for the du command that can be found in the man pages but -h and -s are the most commonly used. Listed below are some additional uses for the command
du -sh ./ - shows the size of the current directory in human readable format without listing any sub directories
du -sh * > outputfile - shows the size of the files and directories in the current directory in human readable format without listing any sub directories directory and sends the output to a file.
du -sh * | grep something - shows the size of the files and directories in the current directory in human readable format without listing any sub directories directory and only lists files or directories with something in the name

My Family Christmas Trip to Universal Studios Japan in Osaka
For Christmas this year, I decided to take my kids to Universal Studios Japan (USJ) in Osaka, Japan. We live in southern Japan and Osaka is only a 2 hour flight so it makes more sense for us to go to USJ vice flying all the way to Los Angeles.
I have never been to any Universal Studios park so I have no basis on which to judge the park in Japan against the parks in the US. I have read, however, that the Japan park is smaller than the parks in the US.
We arranged a package deal through a travel agent in our local city that included air fare, hotel, and park tickets, but not transportation from the airport to the park so we were on our own. There are two options for getting from the airport to the park, the first is the train and the second is a bus. My original idea was to take the bus but I am real fan of the Japanese train systems so I opted for the train once we arrive in Osaka. To get to the train just follow the signs for the train to the JR station that is right outside the entrance to the airport. Be sure to go to the JR station. There is another train that is a local train and will not get you to where you want to go. The cost to get from the airport to "Universal City", which is the train station at USJ is about 1200 yen per person and takes about 1 hour and 20 minutes. You will also have to change trains on the way. Even though I have lived in Japan for 15 years, speak the language, and am familiar with the Japanese train system I had a little trouble figuring out how to purchase the train tickets. There was a very nice station attendant that helped us purcahse our tickets and we were on our way. The first leg of the train trip takes about 1 hour to Nishikujoo where you will have to chnage trains. The announcements are in Japanese and English so figuring out which is the correct stop is not difficult. When you exit the train at Nishikujoo you do not have to go far to get the next train, only about 5-10 feet to the other side of the platform. If you look at the signs it will list Universal City as the destination. The next train is only about 5 minutes and Universal City is the second stop.
When you exit the train you will be in what is know as Univeral City, which is a not a city but a shopping, resturant, and hotel district setup to service customers going to Univeral Studios. We had reservations at one of the hotels in Universak City and it was only about 100 steps from the train station exit. In Univeral City there are numerous resturants such as McDonalds, Mos Burger, Hard Rock Cafe, as well as many Japanese resturants. There are also a number of shops to buy souviners as well as a convience store. Things such as water, food, and other items purcahsed in Univiersal City are much cheaper than items purcahsed in the park. for example a coke purchased at the convience store will run about 150 yen but the same coke in the park will run 250 yen. Univeral City is only 2 minutes walking distance away from the park so it is very wasy to go back to the hotel or to the store and avoid the higher prices in the park.
The hotel we stayed at was the Keihan Universal City. I am not a big fan of most Japanese hotels although I have stayed in some really nice ones. This hotel was clean and warm with just the basics necessary. The beds were too hard and the pillows to small but since our goal was not to spend too much time in the hotel I did not mind too much. The room came with a free buffet breakfast every morning which is exactly like the free buffet breakfast I have had at every other Japanese hotel I have ever stayed at. There must be a national buffet breakfast menu that ever hotel goes off of.
We had two options on our package deal. We could have done a 1.5 day ticket or a 2 days ticket. The 1.5 day ticket is good the day of arrival ater 3 PM and the second day only. The 2 day ticket is good for the second and third day. I opted for the 2 day ticket, which turned out to be a good thing as it rained the first night we arrived. Check the weather before you go and I would suggest buying some cheap over sized parkas that you can slip over your clothes when it starts to rain. A parka at the park will cost 1000 yen when you can get the same item at at 100 yen store.
USJ is a very clean and well organized park. I did not need a map to get around as everything is marked in Japanese and English with signs all over the place pointing you in the right direction. There is only 1 roller coster in the park but there are several other rides that the kids liked as well. Some of our favorites were Spider Man, Back to the Future, Jurasic Park, Jaws, and the roller coaster. ET was okay and back draft too forever to get to the main part which was too short in my opinion but worth seeing once. There are also a lot of shows to see as well. We liked Water World, Wicked, and the Rock and Roll Monster Show. There was also a Peter Pan show that was only played at night which was nice. There were a number of other shows that we did not have time to see or that the kids wanted to skip as the shows were geared toward the younger kids.
Overall we had a great trip. Like everything in Japan it was expensive but I have grown accustomed to that.
Once more word of advice. On the return train tip to the airport make sure you sit in one of the first four cars of the train. Just before the train gets to the airport the train will split in half with the first four cars going to the airport and the back four cars going somewhere else.

Is Linux really 'holding back the kids'?
When I read the article http://www.theregister.co.uk/2008/1215helios_linux_texas_teacher/ at theregister.co.uk about a teacher claiming that Linux is holding back kids and that Windows is a better alternative, I could not believe what I was reading.
It is obvious that the teacher quoted in the article is not up-to-speed with the current status of Linux in the computing world. A majority of super computers use Linux, most of the web servers on the Internet use Linux, and the list goes on.
There are many reasons why Linux is a good operating system to learn but here is my take on the subject. Linux should be a mandatory learning experience for kids, especially kids interested in the IT industry as a career. Much like the learning the basic building blocks for an good education by learning the 2+2=4 and that i comes before e accept after c, learning Linux can provide a life long skill set to an aspiring child that will serve them well throughout their IT life.
When I first learned about Linux it was because my company was sending me to a class to learn UNIX. We were about to get some UNIX workstations and my boss wanted me to have a basic understanding of UNIX. When I got to the class the instructor told us that he would be using Linux, RedHat to be exact, to teach us the basics as at the CLI level almost everything was the same.
Once my class was over I was sent back out into the IT world with my new skill set in UNIX/Linux commands. Little did I know that the basic building blocks I learned in the Linux class would serve me so well in the years to come.
The first thing I noticed when I returned to work was that I had a new fascination with the CLI, even in Windows. Being a Windows users from a very early age I had been infused with the thinking that if it was not in the GUI then it did not exist. I soon learned that even in Windows there are some very powerful tools available only in the CLI and many of the tools were "borrowed" from the UNIX side of the house. When I started getting into networking and was asked to learn how to use Cisco products I was again amazed to find that my UNIX/Linux training paid off as the Cisco IOS is UNIX based and best done through the CLI. When I purchased my daughter a MacBook so she could make video and music projects I was pleased to find that my UNIX/Linux training paid off again as the Mac is UNIX based and the CLI uses most of the same commands. At home I run a mixed environment of Windows, OS X, and Linux and the ability to make all three operating systems work together makes me a more marketable IT person, in my humble opinion. I tell all people that I meet aspiring to enter the IT field to learn Linux, at least the basics, as it will serve them well.
I submit that instead of holding kids back, Linux opens up a whole new world of opportunity. Here is a theoretically example. Let's say that company X is hiring new IT employees and has a limited budget. Company X runs a mixed environment of Windows desktops for the majority of the employees, OS X for the marketing, A/V, and public affairs department, and a mixture of Linux and Windows in the server room. Actually sounds like a lot of real companies. Company X gets a bunch of resumes and starts to weed them out. Do you think Company X wants to hire a Windows only employee, an OS X only employee, and a Linux only employee or an employee that can do all three?

Giving KDE a second chance
When I first started using Linux about 6 years ago, I did not even use any GUI. I preferred to run my Linux as a headless server providing web and other service and connecting from my Windows box via SSH. About 2 years ago, however, I started tying to use Linux as my main desktop. I started using Red Hat, then switched to Debian, tried several other versions along the way, and eventually ended up using Ubuntu. Somewhere along the way KDE fell out of favor with me and I became a Gnome user. It was not love at first site with Gnome, it was something that transpired over several different versions of Linux OS loads. I just kind of liked the simple feel of Gnome.
Now just I am definitely an adventurous person and I like to try new things. I regularly download several different versions of Linux and try each one in a VM just to see what the latest and greatest is in the Linux world. Along the way I have run into a few KDE desktops and usually load the Kubuntu desktop packages on my Ubuntu machines. But I never really got a good feeling for KDE, that is, until yesterday.
I have been reading alot on the Internet about the problems with KDE 4.0 and that 4.1 and now 4.2 made great improvements so I deciede to give KDE a second chance. Since I use Ubuntu I just loaded the kubuntu-desktop packages and switched sessions. I do a lot of photography and I have a saying that I can look at a picture I have taken for about 1-2 seconds and tell if it is a keeper or not. I just clear my mind, look at the picture, and see if it affects me in anyway or tells me a story. I used the same technique with the KDE 4.1 desktop and to my surprise is past the test. I really like the layout of the desktop and the feel of the whole setup from the icons to the color schemes. I have not had a chance to play with all of the customizable functions of the desktop yet but I find the choices available be very appealing.
The only problem that I found so far is that Firefox, my preferred browser, do not look to good in KDE. I did some research and found a couple of fixes that make the browser look a little better but it will do for now.
I think I am going to give KDE a go for a while and see what happens.
