It's Friday - five days after the first HackFMI event was held. I have some interesting statistics derived from the source code of all projects. Read on!
How The Stats Were Calculated
I've used Ohloh to analyze the source code of all projects. A simple Ohloh project called HackFMI 2013 enlists and tracks 18 different repositories as if they were one big project. Not all teams had repositories and some didn't sent information back to me although I asked them. Two projects sent me tarballs with their code, which I've pushed to GitHub for the purpose of tracking stats.
Be aware however that Ohloh is known to produce inaccurate statistics for projects with lots of code and short development history. Furthermore its COCOMO calculations are wrong as well due to duplicate code, not written during the hackathon such as jQuery or PHP libraries.
The Stats
During the weekend sprint 759,453 lines of code were written by 56 contributors spread across 768 commits.
From the top 10 contributors 5 had Python as their primary language. Which is to say Python developers have good development practices with Git.
None of the contributors (excluding myself) were recognized by Ohloh, meaning either they have not contributed to any other open source project or their contributors were not under their name or they've used a different name/email combination. Whatever the case go claim your contributions and track your kudos rank across the open source community.
19 different programming languages were used.
The most popular ones are XML, JavaScript, HTML, PHP, CSS and ActionScript. This is nearly 97% of the source code. All the rest languages have been used under 1% per language. The languages used are pretty standard and expected.
Estimated Cost
The estimated development cost is 205 person-years valued at $ 11,251,680. This is too high because of all duplicated libraries and extra files tracked.
Ohloh allows files and directories to be excluded on per-repository basis. I'd appreciate your help if you preview the projects and create the exclusion rules. Thanks!
The stats and repositories are public. If you manage to extract other interesting details don't hesitate to share them in the comments.
