Edit /etc/ssh/sshd_config and make sure to add the following at the end of the file:
Match group filetransfer
ChrootDirectory %h
I just had to set up Jenkins to use GitHub. My notes (to myself, mostly):
For setting up Jenkins to build GitHub projects. This assumes some ability to manage Jenkins, use the command line, set up a utility LDAP account, etc. Please share or improve this Gist as needed.

Standard for US Driver's Licenses defines 9 different barcode standards (AAMVA versions) with over 80 different fields encoded inside a barcode. Some fields exist on all barcode standards, other exist only on some. To standardize the API, we have structured the fields in the following sections:
| Mat src=imread("card.jpg"); | |
| Mat thr; | |
| cvtColor(src,thr,CV_BGR2GRAY); | |
| threshold( thr, thr, 70, 255,CV_THRESH_BINARY ); | |
| vector< vector <Point> > contours; // Vector for storing contour | |
| vector< Vec4i > hierarchy; | |
| int largest_contour_index=0; | |
| int largest_area=0; |
