fla.gr grew out of my increasing hate for the interface on delicious and a need to always have bookmarks accessible from just about anywhere. I also was looking for a basic scratchpad, with some formating options, preferably markdown enabled. As a result of having just started working with gevent and having built my Seshat framework, I figured this was the perfect time to go about making a new bookmarking service that was what I wanted. And so, with many co rewrites, many revisions and lots of refactoring, I've been slowly building fla.gr from the ground up.
Early versions of fla.gr grew from Seshat, and were powered by a funky, worth nothing UI framework that was meant to be a bridge between Twitter's Bootstrap styled HTML, and Python. I didn't want to go the route of using something like Cheetah or serving a single page app and then making fla.gr an API, and it resulted in a lot of head banging, and pain. In the end, I've gone for Cheetah to render all the templates, and have stuck to writing just plan Python and HTML as mostly separate systems.

A web server, I personally use Lighttpd, fastCGI and support to use it with the webserver, ZeroMQ, Redis, CouchDB, Python 2.7, node.js, and all the node packages and the python packages. The simplest way to get the python and node.js packages and generate the templates is to do:

npm install
mkvirtualenv flagr
pip install -r requirements.txt
make flagr

After this you'll have to setup your static folder so the content in interface/resources/ is available at /static on your web server, along with fastCGI setup to send all results to the server, except for /static to localhost:8080 or whatever port you specify in config.json. For an example of how I do this with my personal dev server see the files included in serverConfig and take a look at seshat/framework.py To make sure your fla.gr server and your webserver are going to play nice with each other. Finally:

cd flagr_core ./firstTime.py ./app.py noDaemon

To test fla.gr out (you might have to chmod +x)

It's recommend by Me to run fla.gr in a Python virtualenv just to be safe and to make sure everything runs smoothly even if you have a more up to date system than I do.

If you have problems with fla.gr not starting due to a NULL result without error in PyObject_Call this is a known problem with GCC4.8, so please try:

pip uninstall greenlets CFLAGS="-O0" pip install greenlet==0.4.0

I won't be of much help if the problem persists, as it is, at the moment, a Greenlets problem. I will only help out if this is something that is directly related to code that I wrote in fla.gr. Aka: Send bug reports and crash dumps to the appropriate project.
