Xueqing (Clare) Tang
Clare Tang is a Full Professor in Computer Science at Governors State University (GSU). The University is on south side of Chicago with diverse student body, which includes large number of non-traditional students transferred from community colleges. The computer science department offers BS and MS in computer science and BS in Information Technology.
Dr. Tang teaches Java Programming, Software Engineering, Data Structure, Algorithms, and Formal Languages and Automata. Dr. Tang participates research projects at Argonne National Lab using supercomputers for computer modeling and simulation on environmental studies. Dr. Tang is passionate on inclusiveness of computer science. She was a Principal Investigator for two NSF funded projects on broadening participation in computing.
Prior to coming to GSU, Dr. Tang spent twelve years working at IBM.
Exercises:
FOSS development life cycle:
Sugarlabs:
Use the software --- tried sugarizer online Report bug --- go to its github site, choose related component, report issue. Check out repository --- Last commit 10/10/2016
Sahana:
Use the software --- browse the web page, very nice Report bug --- go to its github site. At the moment there are 22 issues. Study them as they are good examples to report issue. Check out repository --- Last commit 3/21/2017
Field Trip:
Part 1 - Github:
Search "education" on GitHub. 12,270 repositories are shown.
The first project is "free programming books"
Graphs, then commits shows two charts:
first chart is the weekly total commits for the years;
second chart is the total commits each day of the current week.
Search "Humanitarian", 288 repositories are shown.
HTBox/crisischeckin - last commit August 7, 2016
Search "disaster management", 143 repositories are shown.
Part 2 - OpenHub
Search "education", 346 pages are returned, assuming 10 projects per page, 3460 total projects
Code locations are all on Git, not github.
4 similar projects are listed
OpenHub provides information on line of code, programming languages, activity, community
Search "Humanitarian" - 4 pages; 40 projects
Search "Disaster management" - 6 pages; 60 projects
Why do so many projects do not have activity information available? I need to find out.
Information from "Organizations" tab - lists most active, latest commit volume, newest org, stat by sector
OpenMRS Core App Module - Last commit 2/2017, (says 22 days before)
It seems like OpenHub analyzes it periodically not real time. (says analyzed 22 days ago)
GitHub vs OpenHub: GitHub is more popular, this is the first time I heard OpenHub

Intro to Bug Trackers
Part 1: Bug Reports
ID - number to identify the bug / new feature request
Sev - how severe the bug is
Pri - priority
OS - operating system
Product - the specific part of the software
Status - status of the report such as unconfirmed, confirmed, in-progress, etc.
Resolution - actions taken to fix the bug
Summary - short description of the bug
To find the information, clicked links from the Reports. Bug 777558 User Manual drop-down menu should have a TOC. This bug is fairly recent (January this year) and has been assigned to GIMP BUGS (not sure what this means since it is not a person!). There hasn't been much discussion after it was proposed. To fix it I would first need to install the software to see what it is doing now and then find out what they need to have added to the software. Bug 494314 - Awkward handling of non-existant paths. There's some error handling needed if an invalid path is typed in to make it less intrusive than the current dialog box. The bug was old but was modified recently - not sure what the modifications mean though. I would first make sure the bug was reproduceable to see if it is still an issue. I find it confusing that the assignments are so generic - shouldn't a bug eventually to to a person?
Part 2: Collective Reports Summary: 278 opened, 208 closed in the past week. More opened than closed. Top 3 closers: Reiter, Muktapavels, Chimento. These may be the people who did the most work (although there could be bugs that are taking a while). Top 3 reporters: Lei, Nocera, Plazas There was some overlap between the two lists but not all were on both. Those using the software and reporting problems are not all the same as those making fixes. Patch reviewers and patch contributers overlapped by half. Some of these folks were on the other lists. 19 normal and 10 enhancements for braille Lots of reports for other kinds of bug status
