Python is not a great programming language.

It's great for beginners. Then it turns into a mess.

It's still a work in progress...

Intro

As William Durand was recently explaining in his SOS, he "didn't see any other interesting blog post about REST with Symfony recently unfortunately". After spending some long hours to implement an API strongly secured with oAuth, I thought it was time for me to purpose my simple explanation of how to do it.

Ok, you know the bundles

You might have already seen some good explanation of how to easily create a REST API with Symfony2. There are famous really good bundles a.k.a. :

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

KML to GPX converter

Download GPS data from Google Latitude

Google Latitude location history KML export is very interesting. GPS track log is easy to handle geotagging photos than Google Latitude KML data file. I wrote a perl program to convert from KML to GPX track log.
