Step1. Prepare an OSS

Slide 17

Slide 17 text

Create a Repository - Well begun is half done. - If you don’t mind - on GitHub - MIT Licence - Naming is important - Googleability - cake prefix

Slide 18

Slide 18 text

The name and meta infomartion Lists packages required Autoload mapping

Slide 19

Slide 19 text

Step2. Write codes

Slide 20

Slide 20 text

The most fun process - Describe only bulkInsert() - Please check the repository for details

Decomposed the Entity array data into fields and data Query builder realizes processing of the bulk inser

Slide 23

Slide 23 text

Step3. Write test codes

Slide 24

Slide 24 text

Test codes are necessary for OSS - We can release OSS without test codes - But, OSS without test codes is not reliable for developers - TDD is a good choice

2. Make it better

Slide 40

Slide 40 text

I might as well - Making it useful for many people - not only for self-satisfaction - I researched some popular OSS - found some common points

Slide 41

Slide 41 text

Good OSS has “3Cs” 1. Convenience 2. Clarity 3. Continuity

Slide 42

Slide 42 text

Convenience - Big benefits required - The effort to solve a problem is often more bother than the pain that causes it... - Case: Easy Query - High performance of bulkInsert() - A CakePHP standard method, saveMany() doesn't have it - Inspection: insert 100 records to a tags table - saveMany() 2.93 sec - bulkInsert() 2.01 sec - Enviorment: CentOS6, MySQL5.6, CPU 2core, Memory 2GB (Docker for Mac)

Slide 43

Slide 43 text

Clarity - Anyway can use it quickly - mature documentation - “When in Rome, do as the Romans do” - intuitive and simplie - Case: Easy Query - bulkInsert() has same interface with saveMany()

Slide 44

Slide 45

Slide 45 text

Continuity - GitHub’s star is not all! - The change is drastic - Even a popular OSS is not remembered half a year later - It is also important to improve continuously - Case: Easy Query - I updated it last week - I declare today that I will upgrade Easy Query to CakePHP4 within half a year!

3. Accelerate your OSS activity!

Slide 48

Slide 48 text

Next Step - OSS activity is fun and good! - But, it is difficult to continue...

Slide 49

Slide 49 text

- Connehito has a company program for encouraging OSS activities - Smile Program! - To put it simply, it is an output support program - It started half a year ago Smile Program

Slide 50

Slide 50 text

What is a smile program? - Save up miles when our members contribute to the outside community - Members can then spend miles Engineer A Miles bank Engineer B Save Up! (by Output) - OSS Contribution - Presenting and Writing Spend! (for Input) - Getting certified - Attend Oversea Conferences

Slide 51

Slide 51 text

Concept - Money is not the motivation - When in need of support, a member can get it - Evaluating the value of output and input

Slide 52

Slide 52 text

Let me show you how it actually works

Slide 53

Slide 53 text

Smile Counter - CMS for Smile Program - Featutes - Request for output and input - Review for output and input - Mile management - Member management - Member Rankings - Made with CakePHP4!

Slide 54

Slide 54 text

Why did we start Smile Program?

Slide 55

Slide 55 text

We are raised by the engineer's community Engineer’s Community Connehito Inc Grow! - Using many OSS like CakePHP - Referring to other company’s case study

Slide 56

Slide 56 text

Simply, I want to give back to it.

Slide 57

Slide 57 text

Ecosystem Community Connehito Grow Take - Many OSS - Case Study - Conference Community Connehito Grow Take - Many OSS - Case Study - Conference Give - Contribution - Case Study - Sponsor

Slide 58

Slide 58 text

Win-Win Relationship!

Slide 59

Slide 59 text

Summary - If you have the will, you can create OSS now - Keep in mind the "3Cs" when creating OSS - “3Cs” are Convenience, Clarity and Continuity - Connehito will continue to use CakePHP - And we aim to be an indispensable company for CakePHP community!
