Ruby Meditation 12 - 19.11.2016 If refactoring a ruby code for you is associated with changing an architecture, applying time-proven patterns or updating 3rd party libraries, I can tell that you can get a better result by changing the outside world of your programming logic. #rubymeditation

1. REFACTOR RUBY WITHOUT RUBY
SERGEY PCHELINTSEV

2. QUICK INTRO
JALKOBY -> GITHUB ||TWITTER
E-MAIL -> LINZ.SERGEY@GMAIL.COM
BEER -> HTTPS://TELEGRAM.ME/BEERJSKYIV

3. LET’S STICK WITH THE TERMS
REFACTORING IS THE PROCESS OF RESTRUCTURING
EXISTING COMPUTER CODE WITHOUT CHANGING ITS
EXTERNAL BEHAVIOUR
EXTERNAL BEHAVIOUR IS THE BEHAVIOUR OF AN
ENTITY AS SEEN AT ITS INTERFACE, WITHOUT SEEING
INSIDE THE ENTITY OR ITS OTHER INTERFACES

4. WHAT’S MAKE ME PROUD
REFACTORING
IS A CORE PART OF
THE RUBY IDEOLOGY

5. WHAT’S MAKE ME SAD
FOR THE PAST THREE YEARS THERE WAS ANY NEW THING
▸ the tools ecosystem has been slowdown
▸ speakers talks about the same things over & over
▸ the language doesn’t bring anything awesome
(get ready for the built-in pry on 25.12.2016 🎉😒😒😒)

6. RUBY IN A COMA
John Doe
LONG STORY SHORT

7. HOLD ON, DON’T BE ANGRY
COMA IS NOT THE END
AFTER ALL THIS LEMON CAN GIVE US A MONEY FOR A FEW YEARS

8. JUST DON’T PUT ALL YOUR EFFORT ON IT. OTHERWISE…

9. WHEN YOU ACCEPT THIS, ONE THING WILL HAPPEN*
YOU WILL USE THE
LANGUAGE LESS OFTEN…

10. WHEN YOU ACCEPT THIS, ONE THING WILL HAPPEN*
…
BUT MUCH MORE EFFECTIVELY
*THE EFFECT DOES NOT REPRODUCES ON SHIT CODERS

11. YOU START DISCOVER ONE INTERESTING SIDE-EFFECT
YOUR RUBY CODE
REFACTORS WITHOUT RUBY

12. PHASE 0
YOU START NOTICING THAT
FRONTEND IS NOT A TOY
NOWADAYS

13. PHASE 1 - CSS

14. PHASE 1 - CSS

15. FIRST THEY IGNORE YOU,
THEN THEY LAUGH AT YOU,
THEN THEY FIGHT YOU,
THEN YOU WIN.
Mahatma Gandhi (a senior js developer)
PHASE 2 - JS

16. PHASE 2 - JS
IT WAS A RADICAL CHANGE IN A PAST FEW YEARS
2010 NOWADAYS

17. PHASE 2 - JS
IT STEALS:
▸ Views
▸ Presenters
▸ Helpers
▸ Controllers
▸ Routing
▸ Translation and localization

18. PHASE 2 - JS
ALL YOUR VIEWS IS:

19. PHASE 2 - JS
RUBY IS JUST A THIN LAYER OF
AUTHENTICATION + PERSISTENCE

20. PHASE 3 - AUTHENTICATION & PERSISTENCE
DATABASES ARE NOT MYSQL ANYMORE
▸ JSON is a part of any adequate database
▸ Row Level Security - your database itself manages an
authorisation logic
▸ Database validation functions

21. TO SUM UP
EVEN IF RUBY IS STACK IN 2012,
THE OUTSIDE WORLD
CAN MAKE IT BETTER

22. FOR THE LAST WORD
THANK YOU
