Samenvatting

Go is an increasingly popular language for programming everything from web applications to distributed network services. This practical guide provides recipes to help you unravel common problems and perform useful tasks when working with Go. Each recipe includes self-contained code solutions that you can freely use, along with a discussion of how and why they work. Programmers new to Go can quickly ramp up their knowledge while accomplishing useful tasks, and experienced Go developers can save time by cutting and pasting proven code directly into their applications.

Recipes include:
- Creating a module
- Calling code from another module
- Converting strings to numbers (or converting numbers to strings)
- Modifying multiple characters in a string
- Creating substrings from a string
- Capturing string input
- And so much more

Over Sau Sheong Chang

I am currently the Director of the Applied Cloud Computing Lab in HP Labs Singapore, responsible for managing a team of engineers focusing on researching, developing and testing cloud computing solutions. Amongst research topics I'm investigating include the interactions between the cloud, social media and big data (primarily around Hadoop). Before joining HP Labs, I was the Chief Technology Officer for Garena, a gaming platform and publishing company. and I lead an engineering team to develop, deploy and maintain Garena's software products and games. Prior to Garena, I was Director of Engineering for Yahoo! Southeast Asia, where I led an engineering team in the continual development and maintenance of Yahoo's websites and services for customers in the region. I was also the Head of Yahoo's Developer Network for Southeast Asia, driving developer garages, interactions and forums in across the region. My other past experiences include managing a global software development centre for Welcome Real-time (a global card marketing software provider) as Software Development Director; and co-founding elipva (an e-business solutions specialist) as Chief Architect and VP of Product Engineering. I am an active and keen developer in Ruby and R, and an enthusiast in all things programming and open source. I am also active in various grassroot developer communities in Singapore, especially the Singapore Ruby Brigade. In 2011, I helped to organize the RedDotRubyConf 2011, the largest (and only) Ruby and Rails conference in Southeast Asia. I used to write extensively for various magazines and I have published 2 previous books on Ruby, "Ruby on Rails Web Mashup Projects" in 2008 and 'Cloning Internet Applications with Ruby' in 2010. I have a degree in Computer Engineering from Nanyang Technological University, a Masters in Commercial Law from the University of Derby, and a Graduate Certificate in International Arbitration from the National University of Singapore.
