My new project involves both tornado (as frontend, using tornado-json) and celery (as backend). After googling too much I found two different ways to integrate celery with tornado: using an IOLoop to check for task completion (stackoverflow) using a unix socket (Cyberfart's Blog) I prefer the IOLoop Here is a simple email sender example And the celery task :)

This time we build rethinkdb on ODROID C1. Start with following the tutorial for Raspberry PI. Before start, remember to add swap space (tutorial here) or the compilation will fail. Unlike RPI tutorial, omit "--with-system-malloc" from make command, otherwise you'll get "undefined reference to symbol 'dlsym@@GLIBC_2.4'" error. Take a long break, on my C1 it gets about 5 hours to end ;)

I find crossbar a great gateway for IoT devices. That's how to install it on ODROID C1. I create a directory under /usr/local called crossbar, but you can create it everywhere.

You can add it in two way: use the microsd or emmc space, if you have enough or use an external usb storage. In this post we will use an external usb storage. A really good post to start if you want to use your microsd or eemc is this. Insert your usb key and use dmesg to find the device As you can see, it is recogn...
