More interesting than the stats above however, I downloaded all of the files that were ever uploaded to J2C, UJ, or J2O. I then removed all duplicates (same MD5 hash).

The result is 9257 j2l files.

Fun stats:







And if you are curious about other stats just ask and I can probably figure it out.

An Excel file with all of the data.

Code I used to get this data.
Notes: The code I used to get the data is very rough, I wrote it quickly, may have bugs and is very ugly. You will need to change variables in the main method to point to the directories that you want to search.
To run:
javac *.java
java JJ2LevelStats 1> results.csv 2> errors.txt

And if you have any questions about the code/need more info on how to run it I'd be happy to answer them, I doubt anyone other than Stijn will care though.
