Every year around this time, thousands upon thousands of people vow to change their behavior. “I am going to walk every day!”; “I am going to eat healthier.”; or “I will read more!”, while these goals are great, they either set the expectation too high or do not give a means of measurement.

In order to obtain a goal, it helps to have milestones to achieve. This is good not only for the measurement of your progress but also for the motivation to move forward: “I can achieve this.” …


Arizona State University is a great school for computer science; ASU has been known as a pioneer in online education. Arizona State University offers over 200 online degree programs. The Master’s of Computer Science (MCS) degree is another feather in their cap. With so many feathers, they begin to look like Bartholomew Cubbins.

What makes this program special — and why I chose to attend it — is that you can earn your way into the program even if you don’t have an undergraduate degree in Computer Science, like me. So, how do you earn your way in? …


Week two covered various topics, such as: solving a system of linear equations using Gaussian elimination, LU decomposition of a matrix, as well as finding the inverse of a matrix.

The material is covered very well, though I recommend you speed up the video a bit. The professor covers all topics in an efficient and insightful manner. The problem sets you receive are challenging enough whilst also giving you the opportunity to learn the proofs, essentially the ‘why do these methods work’. I still, to this point, have not seen another course that provides proofs in the assignments along with…


I enrolled in a course from the Hong Kong University of Science and Technology through the Coursera platform. This course was titled Matrix Algebra for Engineers. This course is taught by Jeffrey R. Chasnov.

In the first week, this course covered the introductory concepts to Linear Algebra. We covered how to multiply matrices, how to add and subtract matrices, as well as how to transpose matrices. The material covered was well taught, though I think the teacher could speak quicker than he does. I just put the videos at 1.5x speed.

The homework assignments for the course weren’t too difficult…


This course, which is hosted by Coursera and designed by the University of Pennsylvania, is intended partially as an advertisement for the University of Pennsylvania’s Master of Computer Information Technology (MCIT) degree and partially as a course dedicated to the underpinnings of problem-solving.

This course is comprised of four weeks. A good number of the assignments are peer-reviewed, but the majority of the assignments are done through the use of an autograder. This has both its advantages and disadvantages.

Advantages of the Autograder:

The autograder allows you to complete assignments in a timely manner and receive immediate feedback.

The autograder allows you to see…


This week is dedicated to changing pseudo-code to actual python code. The coding assignment is not too difficult, though the auto-grader is frustrating at times. The week as a whole was quite well done. The information is presented in an efficient, easy to understand manner. The final assignment was challenging for a number of reasons.

The Final Assignment:

The final assignment was a coding project designed around the idea of how to count how many times a word, or its synonyms, appeared in a text. The code was moderately difficult, but nothing beyond the level of knowledge expected of you. The issue stems…


This course in its third week focused on how to write pseudo-code.

The great thing about this course is that it builds wonderfully on itself. In all of the courses I have taken so far, no course built on itself in such an efficient, effective manner. The first week is about how to tackle a problem. The second week is about how to represent that problem with a flowchart. The third week is how to write pseudo-code for the problem. …


What a week it was…

The University of Pennsylvania’s Computational Thinking for Problem Solving course had an interesting second week. As with the first, this week provides plenty of information that is useful on many levels, especially as it pertains to programming. This week focuses on algorithms, in particular, the various types of algorithms. It focuses on efficiency and to take the lessons for week 1 and apply them in an even more practical manner.

The topics it focuses on, in particular, include Linear Search, Logarithmic Search, Quadratic Search, Algorithmic Complexity, Binary Search, and Greedy Algorithms.

While I will not…


An Introduction to the four methods for problem-solving.

The University of Pennsylvania has a course dedicated to problem-solving and how to think about problems you face. This topic is quite interesting and embodies exactly what someone should learn. Learning how to think is, in my opinion, the most important thing that someone could learn. It is a powerful skill that is so frequently glossed over. The first week of this course tackles the skill of how to think by breaking it down to four different steps.

Step 1 — Decomposition

Decomposition is the act of taking a problem and breaking it down into simple…


The learning curve can be quite steep.

I’ve had a difficult time learning to write and am still a student of this wonderful art. Learning to write is hard. I get it and so does every other writer. We understand how much effort it takes to become a good writer. Writers find themselves at various stages throughout this learning process. While there is always room for improvement, there is also a path that has already been traveled. It is important to look at where you’ve been in order to appreciate how far you’ve come.

Before I speak to what I…

I write about programming and computer science as well as review Coursera courses I have taken related to the aforementioned topics.
