This script creates fake commits. It can be used to e.g. confuse GitHub’s Contribution Calendar, which is a privacy issue and cannot be hidden (1, 2) or just impress your (rather naive) employer with your 10.000 commits a day.

I can imagine at least two strategies:

1. swamp your stats with ~100 commits per day for a number of years in a public repo to mask your real commits;
   • it looks like the GitHub calendar may not swallow this…
2. fill up your gaps (e.g. holidays that you don’t want to show to the whole world) with a ‘normal’ number of commits in a private repo and share anonymised commits with the world by:
   1. going to your profile page;
   2. selecting Contribution settings just above your Contributions calendar;
   3. ticking Private contributions.

In order to create fake commits we need some changes to commit, and for that we need (in this case) two files. Make them as small as possible and non-identical, call them file1 and file2 and add them to your fake repo:

mkdir fake-repo && cd fake-repo
git init

echo 1 > file1
echo 2 > file2
git add file1 file2

The changes between commits will consist of swapping the two files (which is why they shan’t be identical).

Then download fake-commits.py into your directory and make it executable.

# Get some help:
./fake-commits.py -h

# You went on holiday for a week and want to fill the gap with a moderate number of commits:
./fake-commits.py -v -f 2001-03-10 -l 2001-03-17 -n 0.2  -P   # See what would happen
./fake-commits.py -vv -f 2001-03-10 -l 2001-03-17 -n 0.2  -P  # See what would happen in more detail
./fake-commits.py -v -f 2001-03-10 -l 2001-03-17 -n 0.2       # Actually create the commits

# If you think you should have committed more:
./fake-commits.py -v -f 2001-03-10 -l 2001-03-17 -n 1  -P  # See what would happen

# If you're a maniac:
./fake-commits.py -v -f 2001-03-10 -l 2001-03-17 -n 100  -P  # See what would happen

# If you're a maniac, but more variably so:
./fake-commits.py -v -f 2001-03-10 -l 2001-03-17 -n 100 -r5 -P  # See what would happen
