There is a site called Ohloh which can be seen as a portal that follows the progress of open source software. Usually every open source project is accompanied by interesting statistics and predictions.
These statistics shows how many lines a code is composed of, how many active developers there are, what language the software was written in and many more bits of information. Yet I find the prediction part most interesting. This prediction shows what the total cost would be if the project was re-made from scratch. This prediction is based on the COCOMO model. The predictions showed many compelling values. Moreover these predictions imply that developers should gain a yearly income of 55.000 dollars!
Here are some total costs of some of the most popular open source projects so far
- Mozilla Firefox: $830.000
- Apache HTTP Server: $2.983.791
- Linux Kernel (Seed Only): $177.004.094
- PHP: $25.023.881
- Open Office: $138.706.367
- GIMP: $19.527.651
- VLC Media Player: $7.163.299
- GNOME: $285.322.119
- KDE: $66.999.594
- MediaWiki (The software behind Wikipedia): $16.792.050
- Wordpress: $1.108.448
- Blender: $31.507. 688
- Debian GNU/Linux: $334.229.025
- Pardus: $19.195.422
We must not forget that these software are only a chosen few. Hence the tip of the iceberg. I think this is very profound situation. What do you think?
