I'm in the iOS Team, YAY!, ;-)

What is m.elcolombiano.com?

• A mobile website made in PHP.
• Reads elcolombiano.com RSS feeds.
• Last month they had like 2.791.914 page views.

How it works?

• A background process run every X time.
• This program get feeds from elcolombiano.com and process each one, also, it saves that information into a DB.
• The program is made in PHP.

golang fits in here! 💪

Rewriting a PHP program into golang…

• The PHP program is OOP.
• All models and business logic is in PHP too.
• Project structure is totally different.

SHOW ME THA CODE!

And… voilà! 

sindyk-feeds-reader

Some stupid numbers…

PHP

✔ ~/Drive/Projects/elcolombiano-mobile-ng/bin [master|✚ 3…1]
08:14 $ APPLICATION_ENV=development time php worker.php

real    54.74

sys     0.19 

golang

✘-1 ~/Drive/Projects/GoLang/src/github.com/nebiros/sindyk-feeds-reader [master|…2]
08:33 $ time go run main/sindyk-feeds-reader.go -dbname elcolombiano-mobile_development

real	0m8.783s
user	0m2.597s
sys	0m0.838s

Simple is better…

• Dig into other golang projects at github.
• Start moving small chunks of code into golang.
• Stop thinking in OOP.
• Look first in the standard library.
• Avoid too much dependencies.

Thank you!
