Haven't you just wanted to work through a coding kata http://codekata.com or puzzle on your phone?
Python is a great language for getting stuff done, and while there are some mobile apps often they are limited by the platform (eg ios sans file system).
Using the link from a Dropbox text file and a linode server (could be openshift red hat cloud?)...
- start running the script on the remote server that waits for new code to execute
python myflaskapp.py & - I can edit using Nocs
- Nocs syncs from iOS to Dropbox
- hitting a URL in my browser
- the python script downloads the latest version of the code (using shell to curl as Dropbox use javascript to authorize and return a link to the latest version)
- executes using the remote python environment
- returns the output
Note! This may be dangerous as hackers could exploit to run arbitrary code, use at your own risk.
*Also, clearly, downloading from Dropbox using curl is a hack with no guarantee of future support =]

Flask Application on OpenShift
git clone https://github.com/openshift/flask-example.git
Use the OpenShift WebUI to create an application
On the right of your application the WebUI has a note on how to clone the default repo:
git clone ssh://12345random@appname-domain.rhcloud.com/~/git/appname.git/
cd appname
git remote add upstream -m master git://github.com/openshift/flask-example.git
git pull -s recursive -X theirs upstream master
git push
cd wsgi/
virtualenv venv
vi myflaskapp.py
from flask import Flask
import os
from subprocess import Popen, PIPE
import urllib2
app = Flask(__name__)
@app.route("/")
def hello():
return "Hello World!"
@app.route('/mysecreturl')
def update_and_run():
output=''
try:
path = '/var/lib/openshift/12345appid/app-root/data/exercises.py'
urlpath = 'https://www.dropbox.com/s/12345random/exercises.py?dl=0'
os.system('curl --silent --location --insecure --output ' + path + ' ' + urlpath)
output = Popen(["python",path], stdout=PIPE).communicate()[0]
# output = Popen(["touch",path], stdout=PIPE).communicate()[0]
except Exception as error:
return str(error)
return output
if __name__ == "__main__":
app.run()
