Programming is a problem solving activity. When you write a program, you are actually writing an instruction for a computer to solve some problem. Overtime,  there are several strategies that have been developed and applied to solve problems. Problem solving is the processing of transforming problem from initial state to a desired  state. Some techniques are more effective while others are less. Here I outline some of the common strategies Trial and Error – This is...

Don’t compete with anybody – set your standards September 26, 2020
As I was talking to a former a student, he asked me what kind of advice I can give him to advance his software engineering career. I quickly told him, do not compete with anybody set your standards! Many times, students tend to compare themselves with their friends in terms of what they are able to achieve including scores. Little do they factor in their own desires and what exactly they want to do with their...

Generating alternative Solutions to Problems August 28, 2018
In the article about problem solving in software engineering, i highlighted the major problem solving steps as:- Define the problem Analyse the problem List/Identify  alternative solutions Select the best solution List instructions that lead to the solution using the selected solution Evaluate the solution In this post, i will focus on how to generate alternative solutions.The first solution you are arrive at may not be best of all possible options. It is important that we generate...

Inspiring quotes on computing April 1, 2018
“It is not only the violin that shapes the violinist, we are all shaped by the tools we train ourselves to use, and in this respect programming languages have a devious influence: they shape our thinking habits.” ― Edsger W. Dijkstra “Program testing can be used to show the presence of bugs, but never to show their absence!” ― Edsger W. Dijkstra

Learning is hard but unlearning is harder July 1, 2016
During the week of  27 June - 29 June 2016 i attended the Summer School on Machine Learning and Data Science at the school at Makereree University dubbed “Data Science Africa 2016”. I happen to sit with a colleague who is an experienced and certified Java Programmer. As we paced through the examples on data cleaning using anaconda package, we relied both on new new knowledge and also tried to apply what we have learnt over...

Turning ‘software’ into a ‘software service’ October 4, 2015
This article looks at how to turn an  existing software that is not service oriented into a service that can be used in a service oriented architecture. We need to know  exactly-  what  is a service?  We are assuming the resulting service will provide  identical functionality. So the  only difference between a software service and other software components is at the interfaces. The interfaces define how the service can be used individually or as part of...

Problem Solving – Analyse/Understand the Problem September 14, 2015
The goal of problem analysis is to gain better understanding of the problem being solved before development begins. It is import to know why the problem is occurring, when and how often. Try to understand the first cause of the problem. Root cause analysis is a systematic way of uncovering the root, or underlying first cause of an identified problem or a symptom to the problem. Tools such as fishbone diagram or pareto chart can help...

Problem solving -Define the problem September 12, 2015
“Until the problem is well defined and articulated it is impossible to arrive at a solution” The first step to solving any software engineering problem is to define the problem. Articulate the problem and eliminate all unnecessary terminologies and jargons. Start by reading the problem completely at least twice. Read and establish the context of each key word. If time allows, research about the problem. Ensure that there is agreement on the problem to be solved....

Software programming and problem solving September 12, 2015
Programming is the process of planning a sequence of steps called instructions for the computer to follow. The fact that you are reading this post you already know that computers lack common sense and cannot make any judgment. So the computer will do as instructed by the programmer through the computer program. Programming is more about problem solving than coding. A problem is the difference between things as perceived and things as desired. A solution will...

To begin with there has been considerable attention to web services  in the last couple of years since early 2000. For starters  web service are no more that applications that are designed to be used across the web. Web services provide a program-to-program programming model where one service invokes another using web standards including the well known HTTP and XML. Here I outline the main benefits, some technical others business. Interoperability – when faced with a...
