Krish Narayanan

Krish Narayanan is a professor in the Department of Computer Science at Eastern Michigan University. She also serves as the undergraduate advisor in the department, a faculty fellow in the Honors College, and the faculty advisor for Women in CS club. She teaches both undergraduate and graduate courses, ranging from Intro to Programming to Advanced Database Systems. Her teaching and research interests are in the areas of databases and software engineering, with a focus on design. She has been actively involved in CS education over the past few years.

In her spare time, she teaches computer science to kids, especially middle and high school girls (Girls in Computing). She has been an avid Science Olympiad coach/supervisor for many years. She runs an event called iCompute for an elementary science olympiad. She has coached a few Girls in Computing teams to compete at the EMU High School Programming competition.

Intro to Wikis

1. How do people interact? Just like other IM interactions.

2. What is the pattern of communication? People in the chat room can communicate with all or with individual users. They can also issue IRC commands like /help.

3. Are there any terms that seem to have special meaning? Any text prefixed with # is a MeetBot command.

4. What advantages might IRC have over other real-time communication methods (like Google Chat or Facebook Messenger?) Are there potential disadvantages? Looks and feels techie! MeetBot and other services are a plus.

5. Can you make any other observations? The MeetBot summarizes the meeting pretty well. I understand that it is more work for the meeting chair but it is worth the trouble.

6. Bonus question: Why didn't Heidi and Darci's actions get picked up by the meetbot? A username is case-sensitive. The MeetBot looks for usernames in interactions for action assignments.

  • last commit was in August 2016

FOSS project hosting


A search for "Education" on the website and further refining the search to "Puzzle Games" resulted in 227 projects. There are 65 Java, 59 C++, 27 Python projects included and many more. Each project has a status associated with it, such as, stable, alpha, planning, etc. These indicate the stage of the development cycle they are in. For example, FindThatWord is in beta testing while FS.WordFinder is in production. The projects can be sorted using different criteria, such as, last updated, most popular, and rating. Brain workshop seems to be the most popular wheres Ohod Quiz Game seems to be the last updated.

I liked these projects:

  • Brain Workshop
  • IncrediBots
  • Sudokuki
  • Build your own jeopardy
  • Brain speed test

Brain Workshop is a Python project implementing a popular brain exercise. It is obvious from the reviews that anyone interested in mental exercises would like this app. There are 5 committers to the project. The last update was in August 2015. This is not a suitable project for contribution since it is well in production. There doesn't seem to be many maintenance/change requests.


OpenMRS is a moderately active project which was analyzed 26 days ago based on code collected 3 months ago. It is mostly written in Java. It is written in 15 languages, such as, JavaScript, XML, and Perl. It has 3.73 million LOC. The top three committers to the project have been active for the last 3-5 years. The average number of contributors in the last twelve months is around 10. The average number of commits in the past 12 months is around 30.

Mousetrap is another interesting project which provides a simple library for handling keyboard shortcuts in Javascript.
