Building Facebook Application in five minutes

Yesterday (June 9th, 2012) I participated Heroku Junior Camp at Rakuten as a staff member. The workshop is designed for Junior Programmers to introduce software development using Heroku. We provided a large company meeting room and I was a beer bash master and drunk as usual ;-)


There were three groups, Java, PHP, and Ruby. I joined the PHP group led by Ando san, who is well known PHP hacker and the author of Candycane https://github.com/yandod/candycane

He introduce to make a Facebook application using Heroku. His presentation in Japanese can be found in his blog. http://blog.candycane.jp/archives/1496


I followed his explanation and click them. What you need is 1) github account, 2) heroku account, 3) Facebook account, that's it. You could make a Facebook application without any coding. very simple.

The application which I made in Five minutes is the following. It is a tutorial of Facebook application.

Using Apple product and Freedom


I am using Mac Book Air since last friday (April 13, 2012). Although I used Mac and Powerbook in early '90, it is the first Apple product in 21 century. I don't use iPod, iPhone, iTunes, iPad, nor any of Apple products.
Mac Book Air at Office

Last weekend I set up new Mac Book Air (mba, here after). By the way, it is a corporate computer so I don't pay it. I had wanted to make software development environment, so did google. I learned Xcode is popular tool. So I tried to download and install it.

You need Apple ID to download it. What is Apple ID? You need to register developer's site to install it. In order to register Apple ID, you have to provide your name, address, birth of date, telephone number and/or credit card number, and so on, to Apple, Inc. In order to register developer's site, you need to provide your Apple ID, affiliation, interests,  development OS, products information, many personal information to Apple, Inc.

I have a netbook which is built by Asus. When I started using it three years ago, I did not accept Microsoft agreement  which means that Windows were erased from my netbook and I didn't use Windows on it but I installed Ubuntu. So I have never provide my personal information to any companies, like Microsoft nor Asus.

I like free software. Because it is free. It means freedom like freedom of speech.

I was shocked that I have to provide my privacy to Apple, Inc. I just want to use this mba but if I want to use it, I have to pay my privacy. It is not free.

Now I understand Richard Stallman never uses Apple products.

Lean Software Development, Leaders Workshop at Rakuten












Today we have a workshop led by Tom and Mary Poppendieck who are well known lean software development experts.

The workshop is in English without translators. As I wrote the previous blog, our company's official language is changing from Japanese to English.

There are good things and bad things without translators.

Bad things; you may have some difficulties to understand what Tom and Mary said. You may misunderstand them. It is very difficult to ask in English.
Good things; You don't need translators. The translation are expensive and sometimes wrong. Communication speed are much faster than having translators.

Poor English is better than translator's translation . You may disagree with me. But my belief is a dialog with poor English makes you clear and concise understanding between each other. Because you have to think about subject very clearly to translate your idea from Japanese (or your native language) to English. If you don't understand what you are talking, you can not translate it to English.

Anyway, Englishnization gives a lot of opportunities for us. I'm really exciting about this company's transformation.

One more thing. "It is easier to ask forgiveness than to ask permission". This is well know agile style or hacker way. I wrote a blog in Japanese. http://d.hatena.ne.jp/hyoshiok/20110205#p1
I learned this quote from Kawaguchi san and he learned from Hiranabe san who attended Mary's keynote speech about lean software development.

This is very exciting moment for me.

Englishnization


Rakuten is known as a Giant EC company in Japan but it is not well known in the world. I am an employee of Rakuten.

Two years ago our CEO said "we will use English as a company's official language" when we had a weekly all company meeting on Monday morning.

Very few Japanese companies use English as an official language. Some of hardware manufactures such as Sony and Nissan are using English but their official language are still Japanese.

It is very radical decision. There is no other choice if a company wants to be a global company.

Two years ago many of us were not good at English and still struggled with it.

We have to pass an English examination. I had never took TOEIC (English examination) so I did not know if I had good enough skill. Fortunately I passed the examination.

Many meetings are running in English now and we get used to use English. Average score of TOEIC are increasing in this two years. We use English in our internal SNS. We can exchange our internal information not only Japanese employees but also non Japanese speaking employees in the world.

Last month we had an internal training by Jonathan Rasmusson at Rakuten. No translation was provided but many of us enjoyed it. Many questions was asked in English.

If we can use English, we can learn the leading edge technology.

Learning English is our great opportunities. English is the language of Internet and the global economy. We are learning the business of Internet services and it is very exciting thing.

Our experience of Englishnization will be a good role model of being a global. How do we change our language to English? I'm enjoying this experience.

Agile Do It!


Yesterday (March 19) I attended 'Agile Do It!'. The program is the following


  • Agile in Nutshell, Jonathan Rasmusson
  • Project Management of Game development, Yoshihisa Hashimoto (CTO, Square Enix)
  • Yahoo!, Rapid Software development, Onozawa (Yahoo!) and Takahashi (Yahoo!)
  • Scrum on DeNA, Kaise (DeNA), Oide (DeNA), Mori (DeNA)
  • Panel Discussion, Nishimura (Eiwa), Jonathan Rasmusson, Tachiki (Yahoo!), Takahashi (Yahoo!), Kaise (DeNA), Komai (DeNA), moderator Kakutani



All of the presentation except Jonathan are case study of each project. Many tacit knowledge were published and discussed. There were many scrum masters and we exchanged our experience.

I think this kind of meetup are very important and valuable. We can learn from each other and exchange our best practice, do/don't, good thing, bad thing and so on.

The after conference party was really good and I enjoyed so much. I would really appreciate DeNA who made the conference, speakers, and participants.
