I WANT TO BE A MORE EFFICIENT DEVELOPER TALK BY @WAXZCE – QUENTIN ADAMAT MIX IT 2014

MY DAY TO DAY WORK : CLEVER CLOUD, MAKE YOUR APP RUN ALL THE TIME

And learn a lot of things about your code, apps, and good/bad design…

KEEP YOUR APPS ONLINE. MADE WITH NODE.JS, SCALA, JAVA, RUBY, PHP, PYTHON, GO…

DEVELOPERS ARE MORE AND MORE CREATIVE

DEVS LEADS A LOT OF BUSINESS

SHIP QUICKLY WORKING APPS

VALUE IS ON PEOPLE MARKET KNOWLEDGE, TEAM MANAGEMENT, PRODUCT OWNERSHIP…

HOW MAKE THEM BE MORE EFFICIENT ?

DEVELOPER HAPPINESS IS KEY

HAPPY PEOPLE PRODUCE BETTER WORK

OPTIMIZE CODE AND PROCESS TO BE HAPPY OF WHAT YOU ARE DOING

OPEN SOURCES WORK PROCESSES ARE BETTER

PEOPLE WRITING CODE BECAUSE THEY JUST WANT TO DO IT

THINK ABOUT

BECAUSE THEY CAN SOLVE PROBLEM OF THE WORLD

BUILD A FRAMEWORK TO PRODUCE CODE EASILY AND SHOW IT EASILY

RELEASE EARLYRELEASE OFTEN

RELEASE EARLYDEPLOYOFTEN

FOCUS ON YOUR OWN ADDED VALUE

DEPLOYMENT HAS TO BE EASY !

BE FOCUS WHEN YOU CODE

GIT PUSH <YOUR_FAVORITE_HOSTING_PROVIDER> MASTER

GIT PUSH <YOUR_FAVORITE_CONTINUOUS_INTEGRATION_SYSTEM> MASTER

OR NOT ;-)

ALL THE TEAM HAVE TO BE READY TO DEPLOY

YOU HAVE TO DEPLOY YOUR APP SEVERAL TIMES A DAY

SPLIT YOUR APP

SPLIT THE CODE : MODULES

SMALLEST CODE BASE POSSIBLE FOR EACH PROGRAM

EACH MODULE IS VIEWED AS A SERVICE BY OTHERSHTTP OR AMQP COMUNICATION

OR AS A CLIENT

USE EVENT BROKER TO MODULARIZE YOUR APP• AMQP• Celery • 0MQ• Redis• JMS• Some case : hadoop, akka…• …

CRON is not an event queue

FOCUS ON THE BEST TOOL TO SOLVE YOUR PROBLEM

DON’T BE THAT GUY

DO NOT USE A TECHNOLOGY BECAUSE YOU <3 IT OR BECAUSE IT’S HYPE : USE IT BECAUSE IT FITS YOUR NEEDS BALANCE YOUR LEARNING CURVE WITH THE TIME SAVED

DO NOT CREATE MONSTERS

LEAR NEW THINGS & INNOVATE

{P, DB, S} aaS

USE OPS FREE SOLUTION TO LEARN AND START

USE ONLINE DATABASE / BE READY TO TEST IN JUST A FEW MINUTES NO NEED TO TRASH YOUR COMPUTER

MAKE ALL DEPLOYMENTS ASYNC MODULE BY MODULE

Statelessness everywhere

AVOID HOST SPECIFIC THINGS

DO NOT USE FILE SYSTEM TO STORE SOMETHING • It doesn’t scale• It’s hard to expose as a service• It’s a SPOF• There is ALWAYS a better option

SCALE YOUR TEAMMODULARIZE YOUR TEAM

SOA IS BACK

TIME WILL TRASH YOUR CODE

THE POWER OF REWRITE EVERYTHING

SMALL CODE BASE + MULTIPLE TECHNOLOGIES = LEGACY KILLER

REWRITE IS QUICK BECAUSE YOU KNOW ALL THE PROBLEMS BEFORE IT HAPPENS

HAPPY DEVELOPER WORKS BETTER : ARE YOU HAPPY WHEN YOU START YOUR IDE?

VERSION EVERYTHING !Data & API

NOSQL JSON DATA NEED VERSION

Get doc on DB

Version check : is there an update to

do ?

Use it at last code version

USE HTTPAND ALL THE GOODNESS IT BRING ON YOUR APP

200 OKBODY : { TYPE : ERROR, MESSAGE : I CAN’T FIND THE FILE }

REALLY ?

PUT SOME TOOLS IN YOUR CODE

USE BUILD MANAGER

LET PEOPLES FREE TO CHOOSE THEIR IDE

USE A CONFIGURATION MANAGER / LIBRARY

LEARN GIT “LIKE A BOSS”

I MEAN : USE GIT WITH CLI

FOCUS ON CODE READABILITY

AVOID EARLY PERFORMANCES OPTIMIZATION

YOU HAVE TO THINK IT’S YOUR FIRST DAY ON THE CODE BASE

AND SOMETHING WILL MAKE YOU HAPPY

A DOCUMENTATION SLIM AS POSSIBLE

WRITE EVERYTHING

DO YOU WORK LIKE THIS ?

EXAMPLE : HOW DOES CLEVER CLOUD WORK ?

SOME OF TECHNOLOGY WE USE

C

ALL TOGETHER USING HTTP & AMQP

THE FAST DEVELOPER WAY
