Jiang (Leo) Li

Jiang Li (a.k.a. Leo) is an Associate Professor in the Department of Computer Science (soon to be a part of the Department of Electrical Engineering and Computer Science) at Howard University in Washington, DC.

Dr. Li has been teaching computer science at Howard University since 2003. His research interests include computer networking and network security. He has been teaching both undergraduate and graduate courses such as data communication, computer organization, computer architecture and programming languages.

The Sugar Labs Project Anatomy

Contributions

Students can be developers (as computer science students) and people persons (as an adult with the assumed social being characteristics), some could be designers or translators as well, depending on their background. All roles need commitment, although the specific tasks are different.

Tracker

There are two types of tickets: defect and enhancement. Each ticket has a number, a title, open time, modification time, owner, description and other miscellaneous items such as severity and milestone etc.

Repository

It's both web-based and local. Source code can be accessed on browsers. If git tools are used, they can be checked out in command line.

Release cycle

Each release cycle has a roadmap, which is updated at the beginning of each release cycle by the release team.

The Sahana Eden Project Anatomy

Contributions

Students can be developers, testers, sys. admin. Some could be documenters, designers or translators as well, depending on their background. The structure seems to be more detailed.

Tracker

Individual tickets are pretty much the same as the Sugar Labs Project, but it has a report system that sort tickets in a different in each report.

Repository

It looks like a local repo, as everything needs to be done in command line.

Release cycle

There is no release cycle, just a roadmap that consists of three milestones. Each milestone seems like a release cycle in the Sugar Labs Project.

Part 1 - Bug Reports

Define what each of the column names below indicate. Include the range of possible values for 2-7 below. Feel free to explore beyond the page to find more information.

ID

 A unique number for each bug.

Sev

 Severity: This indicates how severe the problem is - from blocker ("application unusable") to trivial ("minor cosmetic issue"). One can also use this field to indicate whether a bug is an enhancement request.
 Value range: blocker, critical, major, normal, minor, trivial, enhancement

Pri

 The bug assignee uses this field to prioritize his or her bugs. It's a good idea not to change this on other people's bugs.
 Value range: immediate, urgent, high, normal, low

OS

 The operating system the bug was observed on.

Value range: AIX, BSDI, Cygwin, GNU Hurd, HP-UX, IRIX, Linux, FreeBSD, NetBSD, OpenBSD, Open Solaris, OSF/1, Solaris, BeOS, Mac OS, Neutrino, OS/2, Windows, OpenVMS, other
