Who wrote the questions and study materials?

The questions and answers in the exams and quizzes were written by Sanuja Senanayake based on the lecture notes, discussions, textbook materials and other available resources.

Why do you make them?

Oh the most common question… for a simple reason. I can learn better by creating exam type questions before the exam and a lot of students do it. But the only difference is that I simply decided to post them on the net. In addition, I always like to help others whenever it is possible and enjoying others success. If a single student was able to obtain a high average by using this site as an additional study tool, that will be my greatest satisfaction. So if you find the site useful, please leave a comment so I know that I have helped someone!

No one and please read the disclaimers, warnings and notices posted in various areas of the site.

I do my best to reduce errors and issues. If you find any errors please use the Contact Form to let me know. I will take appropriate actions as soon as possible.

Isn’t that illegal for you to post these question on the public domain?

No, because I made the questions using my knowledge of the subject. Even though notes and materials may be provided by the University of Calgary, I am not breaking any laws. Legally I do not even have to give credits to anyone, but I decided to post credits to respective professors and individuals. If you feel that I have posted something without providing proper credits, please contact me with the details.

Can you post lecture notes and textbooks online?

There are several websites that post PDF version of textbooks and lecture notes online. Under the Copyright laws in Canada and the University of Calgary policies, it is illegal and unethical to post textbooks or lecture notes online (entirely or in parts). Unless a Professor or textbook Publisher and/or author specifically grant permission, this site will not be used as a hub for piracy. If you want access to lecture notes, please contact someone who is enrolled in the particular class.

What is Secure Access and how can I get access to it?

Why are you not accepting comments on this site?

For the public, comments are a great way to express their opinion on published work. For web developers and server administrators, it is an added burden. I used to have a comments section, but even with low visitors volume I ended up with large volumes of spam. At one time, the spam (including pings) have exhausted the server processor and memory and my hosting provider almost suspended the account. It is also sometimes used by hackers to take down or vandalize website. Additionally, I do not have time to moderate discussions. Therefore, the comments (including pings) are no longer accepted by this site.

I’m offended by something I saw on the site. What should I do about it?

A lot of people get offended for one reason or for another. It is just a perks of maintaining a website. If you find something really annoying due to your own personal beliefs sprung out of political, religious, or otherwise ideologies, please feel free to boycott this website. However, if you find errors such as language, factual or web coding errors, please report them here.

I recommend meditation and “walk in the park” techniques for improving tolerance for freedom of speech.

How can I report an illegal content on the site?

All illegal materials will be taken down within five business days after a proper violation request. If you are making a copyright claim, please provide some detail on your original work.

Can I hire you to build my site?

Yes and no. It depends on the time and my school workload. I did some volunteer work for few NGOs in Calgary. I cannot work as your web developer at this moment because I cannot commit to full time contract. If you need some free advice, please send me message and I will do my best to get back to you as soon as possible. If you have a project/job for me, please visit this page. I do NOT run a web business. This is my personal hobby.

What had happened to your old website that ran from 2004 to 2010?

It was taken down and replaced with the current one to improve the performance of the site. The original site was a web design project first created when I was 14 years old. Over the past few years my hobby has outgrown the old pure HTML site.

Why not use a CMS to load all your data from a database with all the flexibility?

I don’t like this method because of two reasons: First would be that there is no way to take full control over how databases and the associated materials. Two, I have to learn how to use whatever the CMS I choose and if I decided, I don’t like it, I have to remove it and learn a new one all over again. This is why I am working on the style sheets so that I can change the entire side with one style sheet similar how CMS operates. However on March 2012 I decided it will take too much time for me to maintain the site and the servers with custom databases. So I decided to use this Wordpess CMS system to run this site.

Why are you in Geology program in University if you like Computer Science so much?

I am aware of my talents in Computer Science. By studying Geology I can add another subject to my skill set. That’s why I am in Geology program. Once I complete my undergraduate degree, I may pursuit a second degree in Computer Science or I may take up on a Masters with specialization in both Geology and Computer Science. There is a growing need for Geoscientists who are also above average computer experts (GIS, well logs, tsunami predication software, etc). I am hoping I can capitalized on that niche market.

Where are your servers located?

In the basement of my parents house in Calgary, Alberta, Canada. I have physical access to the server and you can read about it at here. Update: The site was moved to a hosting service on 22-May-2012.

Why do you need a website?

I don’t need a website, rather I want a website. This is my hobby and I explained well why I love computer technology and software engineering here. I know there are millions of websites out there with similar or same type of materials. Since I love to help others, I believe having access to too much information never hurts.
