//Hello class, my name is Yuji Shimojo and I'm 26. I am from Okinawa, Japan and live there now. I'm in charge of presales of cloud systems integration and application development at an IT company based in Okinawa. Actually, I used to study Information Engineering at University of the Ryukyus in Okinawa, but I dropped out of the college 4 years ago. While in the college, I had lived in San Jose, California for 6 months for an internship. I'm currently majoring in Computer Science with a minor in Business Administration. So, this class is required to obtain my B.S.. I took CMIS242, CMSC335, CMSC350, CMSC325, and CMSC330 as part of my major in the past.

** Week 1 Discussion - The World of Operating Systems [#w351d4e8]

- Question

Name (and post here as a reply to this topic) a few operating systems that you worked on (had contact with).

Describe your experience and answer comparative questions like:

-- Which one was the oldest?

-- What about the oddest?

-- Which one was more fun?

-- etc.

-- Answer
- Answer

My first operating system using was Windows 2000 on my father's PC when I was in elementary school. Since I became interested in it, he bought me a PC with Windows XP. After I entered college, I purchased an iBook with Mac OS 10.4 Tiger because Mac OS was designated by my department. Currently, I am privately using MacBook with Mac OS 10.6 Snow Leopard. In my work, I have used Windows XP/Vista/7 and Mac OS 10.5 Leopard. I also have some experience with CentOS 5.x and 6.x as server operations sytems.

I think Mac OS X is a great operating system. Not only its pre-installed applications are functional and sophisticated, but command-line interface is very strong because it is FreeBSD based. In addition, I can run Windows on my Mac with VMware Fusion if needed.

The oddest and worst operating system I have used before is Windows Vista. There are few good free apps for it, and that was extremely slow especially when it booted up.
