Re: Can you help me to merge your avatars?
Hi! Have you a correspondency table such that using it I can say this person and this one are actually the same physical person? I'm focused on the committers, mailers and bug reporters. I am pretty sure gnome.org has this in the LDAP but I wouldn't like gnome.org to give this information because I consider that confident and private. Actually nearly all commits to git.gnome.org happen with the full name/email which means it is absolutely no problem to link nickname and name here for people that give their correct name. Anyway gnome.org doesn't check in any way that people give their real name so it perfectly possible that people don't use their real name for registration and nobody will ever find out.

Re: Can you help me to merge your avatars?
Hello, Thanks for your very precious and rapid feedback. I talked to my PhD supervisor, Professor Tom Mens about it (head of the software engineering group of the university, in CC of this mail), and he proposed to sign a non-disclosure agreement in which we promise not to make available the information about the physical persons involved (or the identities and logins they use). For our research purposes, the results we will produce will not contain any personal information.Essentially, our results will be primarily numerical and visual results that will be analysed statistically. We will ensure to respect any privacy policy that will be imposed. Concerning your second remark about git.gnome.org, we already use the guidelines you suggest, but they are not sufficient for our analysis purposes, since we still find quite a number of false positives and false negatives during our data analysis, and moreover this data does not contain information about identities used by the maillers and bug trackers. Our goal is to have a really unified view on the different data sources used during OSS development (committers, bug trackers, mailers), which is why the information contained in your LDAP will be very useful to us. Of course, we do not need *all* the information stored in the LDAP, only the information that will allow us to link identities to real persons. (Things like passwords and so on are entirely irrelevant for us, of course.) We therefore hope that we still will be able to obtain the information stored in LDAP (or a reduced version of it, or a similar data source), as it will really help us in understanding how open source software ecosystems evolve. If you wish, feel free to directly discuss with my supervisor about it. In fact, he is sitting next to me while I am writing this mail ;-) Mathieu Goeminne 2010/11/24 Johannes Schmid j...@jsschmid.de Hi!

You will have to ask the sysadmins about it. Anyway, I am pretty sure that git.gnome.org, blogs.gnome.org and bugzilla.gnome.org use different databases and as such don't connect people so you won't get the information you are looking for. irc.gimp.org doesn't use any registration at all. The LDAP is used for git, mail and shell accounts only AFAIK.

I send you a mail because I asked a question on the Brasero IRC chat which said to ask it to you. I'm Mathieu Goeminne, a phd student (at the UMONS, Belgium) and I'm studying the free software ecosystems. A part of my job consists in a merge of all persons involved in free software (including Brasero and Evince). I designed some new algorithms, and implemented others to try to detect real physical persons behind a mail adress, a svn login, a pseudo, etc. In order to validate my algorithms, I need a merge reference, ie, a list of correspondences between all evolved people. I firstly did it manually but there are still errors on my reference. Have you a correspondency table such that using it I can say this person and this one are actually the same physical person? I'm focused on the committers, mailers and bug reporters. I think that as Johannes said, there is no such list. You have a git account, and Bugzilla account, and a mail account, but you're not forced at all to use this e-mail address for the two other accounts. If not, have you an idea about a mean to build this kind of table? I'm afraid you cannot, at least if you mean to get an exact information. People that wanted this information just did like you, by using a few tricks to approach the reality, but we can't be sure their succeeded. See for example the GNOME Census, which has required some reflections about this problem: http://blogs.gnome.org/bolsh/2010/07/28/gnome-census/ The only solution I can see is to validate a part of your data by hand, and then get a measure of what your algorithm got wrong. Then, statistical tests will give you confidence intervals that you'll be able to apply to the broader survey. But I'm sure you thought about this already. ;-) Regards ___ desktop-devel-list mailing list desktop-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/desktop-devel-list

What do you mean for false positives and false negatives? (Not in the statistical definition, in the samples). You can always apply Pareto here: 80% of the code is written by 20% of the total of contributors. And for all of them, it is not hard to fix them (it is harder when you are not used to contributors in the project, but not that hard anyway). You will face bigger problems when mining GNOME git repositories, and you might double/triple count contributions in particular repositories (specially in the Subversion's era). You will find some huge commits with no new code at all (thousands of line of code), or the same history repeated across several repositories with different hashes, and so on. Our goal is to have a really unified view on the different data sources used during OSS development (committers, bug trackers, mailers), which is why the information contained in your LDAP will be very useful to us.

(Things like passwords and so on are entirely irrelevant for us, of course.) Peter Rigby has worked in unifying committers and mailing lists, and -as far as I know- he used some techniques proposed by Chris Bird (I do not have the reference at hand, but you will find them).

I am pretty sure gnome.org has this in the LDAP but I wouldn't like gnome.org to give this information because I consider that confident and private. It is not in LDAP. LDAP contains userids, names and email addresses for SSH accounts. We do not store peoples configured git identity setting, nor their Bugzilla id, nor the email address used on mailing lists. The LDAP email addresses might: * reflect what a user configured in Git, but it doesn't have to be the case * be the same as their Bugzilla email address, but might not (e.g. for me) * be the same as what is used on a mailing list, but not required But in every case: could be the same, could be different. Also, we update LDAP details when requested. History is not kept. -- Regards, Olav ___ desktop-devel-list mailing list desktop-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/desktop-devel-list
