Javascript
Javascript• Javascript and HTML
• HTML: Web Document Content
• Javascript: Client-side script to interact with the user, alter web content, control web browser, communicate asynchronously.
• Node.JS: Server-side network programming
Node.JS Case #1 - LinkedIn
• http://engineering.linkedin.com/nodejs/blazing-fast-nodejs-10-performance-tips-linkedin-mobile
• “In a previous post, we discussed how we test LinkedIn's mobile stack, including our Node.js mobile server. Today, we’ll tell you how we make this mobile server fast. Here are our top 10 performance takeaways for working with Node.js:….”
Node.JS Case #2 - Walmart• http://venturebeat.com/2012/01/24/why-walmart-
is-using-node-js/
• “… Now, on Walmart’s re-engineered Node-powered mobile app, all the front-end code gets executed on the back end…”
• “We’re really excited to have a viable back end for that,” he continued. “That’s why Node really excited us, and at Walmart, we’re doing a lot with that kind of architecture right now.”
Javascript Visualisation - Tokyo Wind Speed
• http://air.nullschool.net/
• Source Code: https://github.com/cambecc/air
• It is a Node.JS project.
• Render SVG with D3.js and 300KB Geographic data of Tokyo in a TopoJSON file.
Python
Python• Python can serve as a scripting language for web applications.
• via mod wsgi for the Apache web server.[
• Web application frameworks written in Python.
• Django, Pylons, Pyramid, TurboGears, web2py, Tornado, Flask and Zope
• support developers in the design and maintenance of complex applications.
• The Raspberry Pi single-board computer project has adopted Python as its principal user-programming language.
Python• Core philosophy of Python language syntax design.
• Beautiful is better than ugly
• Explicit is better than implicit
• Simple is better than complex
• Complex is better than complicated
• Readability counts
Python Case #1 - Dropbox• http://techcrunch.com/2013/07/11/how-did-
dropbox-scale-to-175m-users-a-former-engineer-details-the-early-days/
• “… Another great learning from the early days was this: They used Python for everything. And it worked…”
• By using Python for it all “we could get to 40m users without having to write thousands of lines of C code.” Even the client app was written in Python.
Python Case #1 - Dropbox• http://highscalability.com/blog/2011/3/14/6-
lessons-from-dropbox-one-million-files-saved-every-15-minu.html
• 99.9 % of their code is in Python. Used on the server backend; desktop client, website controller logic, API backend, and analytics.
• Release Early: Code something in a day and release it. Python makes that easy.
Python Case #2 - Google• Python is 1st programming language supported by
Google App Engine, which consumer can write python codes to run on Google datacenter infrastructure.
• “Python has been an important part of Google since the beginning, and remains so as the system grows and evolves. Today dozens of Google engineers use Python, and we're looking for more people with skills in this language." said Peter Norvig, director of search quality at Google, Inc.
Python Case #3 - Youtube
• "Python is fast enough for our site and allows us to produce maintainable features in record times, with a minimum of developers," said Cuong Do, Software Architect, YouTube.com.
Data Science
Data Science
• Big Data
• Open Data
• Others
Data Science
• Open Source Programming Languages for Data Science
• R
• Python with SciPy, NumPy
R
• R is a open source programming language and software environment for statistical computing and graphics.
• Widely used among statisticians and data miners for developing statistical software and data analysis.
Open Data• 3 Laws of Open Data.
• Searchable: Free to access and use.
• Structured Data: Machine-readable.
• Re-purpose: Legal Framework allows data to be re-purposed and re-distributed.
• Similar concept of Open Source.
Implementing your business ideas and solutions with Open Source related tools• Front-ends:
• Web (Standard): Javascript
• Mobile:
• Android, iOS apps connecting to your back-end services.
• Firefox OS (Open Source): Gecko including javascript.
• Back-ends:
• Implement APIs with Open Source Software: Python, PHP, Ruby, Java, Perl……
• Access Data
• Open Source Database Systems: MySQL, Postgesql, MongoDB……
• Open Data ?
• Open Source Operating Systems: Linux
Global Open Source Development - 2015 Forecast
