CVSAnalY_SF update - project unixname

Submitted by megan on June 26, 2006 - 1:17am
Today we got notice from the CVSAnalY folks that their data now maps to ours via unix projectname. (CVSAnalY_SF is a project that mines data from CVS repositories, such as those for projects hosted on Sourceforge.)

He writes:
You can find data, schema, explanation and known bugs at:

this data set may be more interesting to you as it includes now the

Social Network analysis over time using FLOSSmole data

Submitted by jhowison on March 10, 2006 - 5:56pm
Just sent off the camera ready version of a paper built using data available in the tracker tables of the FLOSSmole database.

Howison, J., Inoue, K., and Crowston, K. (2006). Social dynamics of free and open source team communications. In Proceedings of the IFIP 2nd International Conference on Open Source Software, Lake Como, Italy. Available from: http://floss.syr.edu/publications/howison_dynamic_sna_intoss_ifip_short.pdf

This paper furthers inquiry into the social structure of free and open source software (FLOSS) teams by undertaking social network analysis across time. Contrary to expectations, we confirmed earlier findings of a wide distribution of centralizations even when examining the networks over time. The paper also provides empirical evidence that while change at the center of FLOSS projects is relatively uncommon, participation across the project communities is highly skewed, with many participants appearing for only one period. Surprisingly, large project teams are not more likely to undergo change at their centers.

tips for using the query tool

Submitted by megan on March 7, 2006 - 12:30am
NOTE: This message describes an old query tool. The old query tool has been replaced with the new query tool. The new tool is located here: New Query Tool


Original message:
If you use the query tool, be aware that the amount of data in some of our tables is truly immense.

Tips:

1. do a "describe" on each table to see what's in there first:

"describe fm_projects"

This will tell you the structure of the table.

2. If you want to see a few sample rows, and you feel as though you simply MUST do a "select *", at least do your select with a mysql-style "limit" phrase like this:

"select * from fm_projects limit 25"

3. If you get an error describing something like a "timeout", this means your query was probably just too large. Email or chat with us on IRC or AIM to figure out what is wrong or a way to optimize the query.

4. Use the text files - many of the queries you want are the same queries that everyone wants! So we've taken the liberty of making text files of these items for your convenience.

tidbit: freshmeat and sourceforge

Submitted by megan on March 7, 2006 - 12:16am
Freshmeat (FM) describes itself thusly: "freshmeat maintains the Web's largest index of Unix and cross-platform software, themes and related 'eye-candy', and Palm OS software."

And Sourceforge (SF) is, of course, "the world's largest Open Source software development web site, hosting more than 100,000 projects and over 1,000,000 registered users with a centralized resource for managing projects, issues, communications, and code."

Here at FLOSSmole, we keep tabs on Freshmeat AND Sourceforge projects. Some of the projects listed on Freshmeat are also listed in Sourceforge, and some of them are not. One way to tell which SF projects are listed on FM is to query our Freshmeat tables and ask which Freshmeat projects resolve to a "sf.net" or "sourceforge" URL:

SELECT count(*)
FROM fm_project_homepages
WHERE datasource_id=18
AND real_url_homepage LIKE "%sourceforge%"
OR real_url_homepage LIKE "%sf.net"

For the March 5 data (datasource=18), this yields 10278 results.

Other things we track about Freshmeat projects are the authors, the dependencies (what other software is this software dependent upon?), and how the project is classified in the trove.

The tables you'll be interested in are:

fm_project_authors
fm_project_dependencies
fm_project_homepages

Some pretty pictures to amuse you...

...while we get February's data parsed and loaded.

These graphs showing December 2005 trends were made by FLOSSmole's newest developer.

Most connected developers - I really like this chart because it shows that the most connected developer on Sourceforge (i.e. member of the most projects) is a graphic designer! How cool is that? This makes perfect sense when you think about it for a second, but it wouldn't have been MY first guess.

Here are some older charts, similar to things we have run before - these graphs show the kinds of reports you can run using FLOSSmole data:

SF project descriptions

Submitted by megan on January 7, 2006 - 4:24am
We got a request for Sourceforge project descriptions. These are the little paragraphs that the project owners write to describe a given project. I've parsed out the descriptions and put them in this file release. Also, I created a new table called project_description to hold this information if you're using the query tool.
