I once designed and implemented most of the pardus package manager called pisi.
However, my “coworkers”, some of which were envious of my prowess, and no bullshit attitude, and who also wanted to hide the fact that they did not contribute anything significant, first removed the author comments in the files, and then removed my svn account, making it look as if I made only a meager contribution.
The fact, however, is that, I’ve implemented almost everything in pisi, except for the implementation of the build commands. All of the architecture, xml processing, database, commands, operations, dependency resolution, other algorithms (like graph algos etc.), CLI, API, and many other details that I forgot are entirely my coding. At any rate, most other coders did not really know how to design algorithms (Ismail definitely knew), or use advanced features like metaclasses, and even if they could they were mostly lazy people when it came to this project. However, they all wanted to take credit for the project, maybe that’s why they are listing authors in alphabetical order nowadays, because they obviously want to conceal my contribution. So, I’m telling you, I’ve written about 80% of the code, perhaps more. In some files I was written as the author. In every file that didn’t list the author, the author was most certainly me. And the remaining 20% was written by Baris, and Caglar, in that order. Baris wrote the build commands. And Caglar implemented actionsapi. That was the extent of their contributions, and Baris also did some bug fixes but I did most of the bug fixes (about 300 bugfixes including several wishlists!). Caglar was pretty hard working, he designed most of the packages. The other “authors” in the current pisi svn version, are more correctly called only contributors. If you’re curious to see the real AUTHORS file it goes something like this:
sirius:pisi malfunct$ cat AUTHORS
Authors and contributors
------------------------
Eray Özkural
Barış Metin
S. Çağlar Onur
A. Murat Eren
Faik Uygur
Gürer Özen
İsmail Dönmez
Görkem Çetin
Bahadır Kandemir
Ahmet Aygun
Onur Küçük
Furkan Duman
This was in order of contributions. Murat implemented about one python module, just some file operations and some progress thing. After that, the contributions are negligible, a function or two. Some fixes. Things like that. So only the first four are real authors, and I’ve written most of the code. This was how the pisi 1.0 release was made.
I am saying this, because I know for a fact that some people are taking credit for work they have not done themselves, which should speak for their professional integrity.
UPDATE: Here is also the TODO file, which I believe these plagiarists must have removed from svn to conceal what they have done. Here it is, basically I wrote everything except the build commands and actions API as I said. I thank the co-authors who did real work on that project, and I condemn those who pretend to have contributed to the original code. I resent that people can sink so low as to try to undermine the work of the lead author. There is also an svn graph that shows the commits etc. but I can’t seem to find it, maybe it was in my uludag homepage.
On every line the contributor is not listed, it was me, I used this file to track my progress on the project.

If you take a look at the README file which was also written by me of course, all of these features were designed and implemented by me. It was my idea to do everything in python anyway, and I ended up coding up 80-85% of PiSi. I implemented everything that’s non-trivial, that is!
PISI - Packages Installed Succesfully as Intended
PISI is a new package manager for the PARDUS
distribution. In Turkish PISI means "kitty", and
like a kitty, it is featureful and small.
Some of its distinctive features:
- Implemented in python
- Efficient and small
- Package sources are written in XML and python
- Fast database access implemented with berkeley DB
- Integrates low-level and high-level package operations (dependency resolution)
- Framework approach to build applications and tools upon
- Comprehensive CLI and a user-friendly qt GUI (distributed separately)
- Extremely simple package construction
The only thing I got when I started the project was the XML format idea basically and a generic design document that didn’t have any algorithms or any interesting design in it. Surprisingly, after the 1.0 release, the authors of that document we all collaborated on was changed as if it was written by only Baris, which was also plagiarism!
Pay attention to the little details!
